I have this is WordPress Post editing Url:
https://example.com/wp-admin/post.php?post=ID&action=edit
and I want to change it to Slug Not the ID Like This:
https://example.com/wp-admin/post.php?post=Slug&action=edit
I was trying to edit the post with this Url but is not working:
https://example.com/wp-admin/post.php?post=MyPostSlug&action=edit
In order to change the edit post link structure, you can use the get_edit_post_link filter like so:
add_filter( 'get_edit_post_link', 'so_73914075_get_edit_post_link', 10, 3);
function so_73914075_get_edit_post_link($link, $post_id, $context) {
$post = get_post( $post_id );
if ( ! in_array( $post->post_type, array( 'post', 'page' ) ) ) {
return $link;
}
$post_type_object = get_post_type_object( $post->post_type );
if ( 'revision' === $post->post_type ) {
$action = '';
} elseif ( 'display' === $context ) {
$action = '&action=edit';
} else {
$action = '&action=edit';
}
if ( 'display' === $context ) {
$post_type = '&post-type=' . $post->post_type;
} else {
$post_type = '&post-type=' . $post->post_type;
}
$custom_edit_link = str_replace( '?post=%d', '?post-name=%s', $post_type_object->_edit_link );
return admin_url( sprintf( $custom_edit_link . $action . $post_type, $post->post_name ) );
}
This will change the edit links for regular posts and pages to something like this:
https://example.com/wp-admin/post.php?post-name=the-post-slug&action=edit&post-type=post
WARNING: make sure you limit this to only the post types you need to change the URL for. Making this change global will almost surely
have unintended effects over other plugins
However, making the admin panel actually load the edit screen is not that easy.
Looking at the source code of the wp-admin/post.php file, you will see that there is no way to hook into the flow and populate the $post_id variable with the post id matching the slug you are sending through.
That means you have 2 options:
RECOMMENDED Update the edit link to whatever format you want and then create an admin redirect function that pulls the slug from the initial URL and redirects to the actual edit page with the ?post=%d in it.
NOT RECOMMENDED Create a new admin edit page that will understand your URL structure and include the wp-admin/post.php after the code that pulls the $post_id based on the slug.
The 2nd method might come with lots of extra code you need to write to cover all the cases and all the instances a post reaches the post.php in the admin panel
I need to output a certain product page on the homepage. add_rewrite_rule doesn't work for homepage for any reason (
there are actually no rewrite rules for the homepage in the database, WordPress seems to use some other functions to
query the homepage):
//works fine
add_rewrite_rule( 'certainproductpage/?$',
'index.php?post_type=product&name=certainproduct',
'top'
);
//does not work
add_rewrite_rule( '', //tried everything like "/", "/?$" etc
'index.php?post_type=product&name=certainproduct',
'top'
);
After spending way too much time looking through wp / wc core code and stackoverflow I came across an alternative. I can
simply add a shortcode in the content of the page I need to be the homepage and a product page at the same
time: [product_page id=815]. Indeed it works great, but only if the shortcode is added in the admin editor or is
stored in the database (post_content). If I try to call the shortcode manually on the page template (
page-certainproductpage.php) then it outputs the product page without some necessary stuff (PayPal, PhotoSwipe and
Gallery js). Weirdly enough, if I keep the shortcode in the content (via Gutenberg / Code Editor) but don't
call the_content and only echo the shortcode then everything works fine:
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
get_header( 'shop' );
//works fine only if the same shortcode is within the certainproductpage's content
echo do_shortcode("[product_page id='815']");
//the_content();
get_footer( 'shop' );
Also when I try to add the shortcode via the_content filter hook before the do_shortcode function is applied in core's
default-filters.php ($priority < 11), then I get only the error:
NOTICE: PHP message: PHP Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/html/wp-includes/functions.php on line 5106
Unfortunately there is no stack trace logged. And the function around line 5107 is wp_ob_end_flush_all which is called on shutdown from default-filters.php
echo do_shortcode(apply_filters('the_content', "[product_page id=815]")); did not help either (same incomplete output as
with echo do_shortcode("[product_page id=815]");)
Also totally weird:
When I compare the string of the content from the editor and the string of the shortcode added programmatically it is
equal!:
add_filter( "the_content", function ( $content ){
$wtf = "<!-- wp:paragraph -->
<p>[product_page id=815]</p>
<!-- /wp:paragraph -->";
$result = $wtf === $content;
?><pre><?php var_dump($result)?></pre><?php
return $content;
}, 1 );
But if I replace return $content with return $wtf - I get the maximimum exucution time exceeded error.
So how can I properly output a product page on the homepage ("/") or how can I get the same result with the shortcode
when applied within the the_content filter as when just adding the shortcode in the (Gutenberg) editor?
Update
Tested it with a simple custom shortcode outputting only a heading tag and it works fine with the_content filter. Also tried it on an absolutely clean site with only WooCommerce and PayPal installed - with the same results. Seems to be a bug on the WooCommerce side. Gonna run it through xDebug some day this week.
Ok, found a bit of a hacky solution. I just check on every page load whether the homepage is currently queried or not. Then I get the page content and check if it already contains the shortcode. If not then the page content gets updated in the database with the shortcode appended.
//it has to be a hook which loads everything needed for the wp_update_post function
//but at the same time has not global $post set yet
//if global $post is already set, the "certainproductpage" will load content not modified by the following code
add_action( "wp_loaded", function () {
//check if homepage
//there seems to be no other simple method to check which page is currently queried at this point
if ( $_SERVER["REQUEST_URI"] === "/" ) {
$page = get_post(get_option('page_on_front'));
$product = get_page_by_path( "certainproduct", OBJECT, "product" );
if ( $page && $product ) {
$page_content = $page->post_content;
$product_id = $product->ID;
$shortcode = "[product_page id=$product_id]";
//add shortcode to the database's post_content if not already done
$contains_shortcode = strpos( $page_content, $shortcode ) > - 1;
if ( ! $contains_shortcode ) {
$shortcode_block = <<<EOT
<!-- wp:shortcode -->
{$shortcode}
<!-- /wp:shortcode -->
EOT;
$new_content = $page_content . $shortcode_block;
wp_update_post( array(
'ID' => $page->ID,
'post_content' => $new_content,
'post_status' => "publish"
) );
}
}
}
} );
I'd recommend one step at a time. First of all, does this work?
add_filter( "the_content", function ( $content ) {
$content .= do_shortcode( '[product_page id=815]' );
return $content;
}, 1 );
This should append a product page to every WordPress page/post.
If it works, then you need to limit it to the homepage only, by using is_front_page() conditional in case it's a static page:
add_filter( "the_content", function ( $content ) {
if ( is_front_page() ) {
$content .= do_shortcode( '[product_page id=815]' );
}
return $content;
}, 1 );
If this works too, then we'll see how to return a Gutenberg paragraph block, but not sure why you'd need that, so maybe give us more context
I'm trying to show some calculated information after each comment, which are planned to be displayed only in 'product' post type. I have no problem with making the function work, it is showing what I want, but it also causes fatal errors on my website, for example the Comments section in admin panel. How can I make sure that these information are only shown in post type of 'product' and doesn't cause any errors anywhere else? My attempt is as follows:
function comment_significance_indicator ($content, $comment) {
global $wpdb;
global $current_user;
global $post;
$post_type = get_post_type( $post->ID );
if ($post_type === 'product') {
//some stuff happens here
return $content . $blabla;
else {
return $content;
}
}
add_filter("comment_text","comment_significance_indicator",50,2);
Thanks for any help.
write the code when the post_type == product like below:
if ($post_type === 'product') {
function your_func(){
return ;
}
add_filter("comment_text","comment_significance_indicator",50,2);
}
I have a website with some custom post type created with Ultimate CMS plugin.
In admin area, when I make a new search, the result is ok, but after that, when I'm try to make a second search, It give me an error "Invalid post type".
I also realize that the url it's not ok:
In the first search, the url is something like this:
http://www.site.com/wp-admin/edit.php?s=SearchTerm1&post_status=all&post_type=post&action=-1&m=0&cat=0&paged=1&mode=list&action2=-1
In the second search, the url is something like:
http://www.site.com/wp-admin/edit.php?s=SearchTerm2&post_status=all&post_type=Array&_wpnonce=4d88f268e4&_wp_http_referer=%2Fwp-admin%2Fedit.php%3Fs%3DSearchTerm1%26post_status%3Dall%26post_type%3Dpost%26action%3D-1%26m%3D0%26cat%3D0%26paged%3D1%26mode%3Dlist%26action2%3D-1&action=-1&m=0&cat=0&paged=1&mode=list&action2=-1
And the error message: "Invalid post type".
I deactived all of my plugins, I upgraded wordpress to the latest version 3.5.1, I reset permalinks to default, but this error still remain.
Any help would be much appreciated!
Thank you
I also came across this issue and found that it was a result of one of my functions in my functions.php file that was modifying the global wordpress query parameters.
It sounds like you edited the global $query object. If you used a hook such as 'pre_get_posts' and manipulated the $query object and you do not exclude the admin area, then any changes you make to the query parameters will also apply to the admin panel and it will display that error when trying to add in parameters that don't fit your search.
For example:
Let's say you have a search feature on your site, and when the user enters a search and goes to the search results page, you only want to display posts of a custom post type called $searchable_posts, then you would add a hook to your functions.php file like this:
function searchfilter($query) {
if ($query->is_search && $query->is_main_query() ) {
$query->set('post_type', $searchable_posts);
}
return $query;
}
add_filter('pre_get_posts', 'searchfilter');
This will make it so that any global default $query will only search for results that have a matching post type of $searchable_posts. However, the way it is written above means this will also apply to any global $query in the admin panel also.
The way around this is to structure your query like this:
function searchfilter($query) {
if ($query->is_search && $query->is_main_query() && !is_admin() ) {
$query->set('post_type', $searchable_posts);
}
return $query;
}
add_filter('pre_get_posts', 'searchfilter');
Adding in that !is_admin() means that your function will exclude anything in the backend administration panel (see is_admin ).
Alternatively, a safer way if you can, instead of using the global default $query is to create your own new WP_Query and searching using that instead - the codex has good examples of how to set that up.
I am also get the issue same as you and finally I got the solution.
We have to add $query->is_main_query() in IF CONDITION.
Below is the full code.
function acf_meta_value_filter() {
global $typenow;
global $wp_query;
if ( $typenow == 'your_custom_post_type_name' ) { // Your custom post type meta_key_name
$plugins = array( 'value1', 'value2', 'value3' ); // Options for the filter select field
$current_plugin = '';
if( isset( $_GET['meta_key_name'] ) ) {
$current_plugin = $_GET['meta_key_name']; // Check if option has been selected
} ?>
<select name="meta_key_name" id="meta_key_name">
<option value="all" <?php selected( 'all', $current_plugin ); ?>><?php _e( 'All', '' ); ?></option>
<?php foreach( $plugins as $key=>$value ) { ?>
<option value="<?php echo esc_attr( $value ); ?>" <?php selected( $value, $current_plugin ); ?>><?php echo esc_attr( $value ); ?></option>
<?php } ?>
</select>
<?php }
}
add_action( 'restrict_manage_posts', 'acf_meta_value_filter' );
function acf_meta_value_filter_by_slug( $query ) {
global $pagenow;
// Get the post type
$post_type = isset( $_GET['post_type'] ) ? $_GET['post_type'] : '';
if ( is_admin() && $pagenow=='edit.php' && $post_type == 'your_custom_post_type_name' && isset( $_GET['meta_key_name'] ) && $_GET['meta_key_name'] !='all' && $query->is_main_query()) {
$query->query_vars['meta_key'] = 'meta_key_name';
$query->query_vars['meta_value'] = $_GET['meta_key_name'];
$query->query_vars['meta_compare'] = '=';
}
}
add_filter( 'parse_query', 'acf_meta_value_filter_by_slug' );
I had a similar problem with a site a took over from other dev.
function anty_search_form( $query ) {
if ( $query->is_search ) {
$query->set( 'post_type', array('post', 'product') );
}
return $query;
}
add_filter( 'pre_get_posts', 'anty_search_form' );
Someone forgot to exclude this function from wp-admin page. So changing to this helped Invalid post type.
function anty_search_form( $query ) {
if (!is_admin()){
if ( $query->is_search ) {
$query->set( 'post_type', array('post', 'product') );
}
return $query;
}
}
add_filter( 'pre_get_posts', 'anty_search_form' );
At wp-admin when submitted the second search for a custom post type, I was getting the same error, "Invalid post type." The URL seemed long and incorrect. Anyway, the following code worked perfectly:
add_filter( 'pre_get_posts', 'tgm_io_cpt_search' );
function tgm_io_cpt_search( $query ) {
if ( $query->is_search ) {
$query->set( 'post_type', 'your_custom_post_type' );
}
return $query;
}
What PHP code can be used to retrieve the current page name in a WordPress theme?
All the solutions I have seen so far:
the_title()
get_page()->post_name
get_post()
etc.
But these don't work for a page that contains post entries. They will all return the name of the latest blog entry.
Stated another way, assume that you have a page created in WordPress with the name "My News". This page is set as the "post page". Add a couple of posts to the page.
Now, what API can be used to retrieve the string "my-news" instead of the name of the latest post?
I've found the following variable which seems to work.
$wp_query->queried_object->post_name
This is actually the URL friendly version of the page name (slug), which is what I was looking for too. This was tested with the default template (Twenty Ten). I'm really not sure why the two variables given below do not work on my site. Thanks to keatch for the print_r() tip.
Now, why is this information hidden so deep down?
The WordPress global variable $pagename should be available for you. I have just tried with the same setup you specified.
$pagename is defined in the file wp-includes/theme.php, inside the function get_page_template(), which is of course is called before your page theme files are parsed, so it is available at any point inside your templates for pages.
Although it doesn't appear to be documented, the $pagename var is only set if you use permalinks. I guess this is because if you don't use them, WordPress doesn't need the page slug, so it doesn't set it up.
$pagename is not set if you use the page as a static front page.
This is the code inside /wp-includes/theme.php, which uses the solution you pointed out when $pagename can't be set:
--
if ( !$pagename && $id > 0 ) {
// If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
$post = $wp_query->get_queried_object();
$pagename = $post->post_name;
}
My approach to get the slug name of the page:
$slug = basename(get_permalink());
<?php wp_title(''); ?>
This worked for me.
If I understand correctly, you want to get the page name on a page that has post entries.
Ok, you must grab the page title before the loop.
$page_title = $wp_query->post->post_title;
Check for the reference: http://codex.wordpress.org/Function_Reference/WP_Query#Properties.
Do a
print_r($wp_query)
before the loop to see all the values of the $wp_query object.
You can get the current page, post, or custom post type with the global variable $post:
echo $post->post_title
Note: In a function or class you'll need to specify global $post; prior to trying to use $post.
If you have loops on your page, make sure you end each loop with wp_reset_postdata(); to set $post back to the default item being displayed (the page).
Note, the 'post_title' variable is also available for any custom loop / query... including menu items and media attachments... everything in WordPress is a 'post'.
We just need to use the "post" global variable:
global $post;
echo $post->post_title;
This will echo the current page/post title.
If you're looking to access the current page from within your functions.php file (so, before the loop, before $post is populated, before $wp_query is initialized, etc...) you really have no choice but to access the server variables themselves and extract the requested page from the query string.
$page_slug = trim( $_SERVER["REQUEST_URI"] , '/' )
Note that this is a "dumb" solution. It doesn't know, for instance that the page with the slug 'coming-soon' is also p=6. And it assumes that your permalink settings are set to pagename (which they should be anyway!).
Still, can be a useful little trick if you have a controlled scenario. I'm using this in a situation where I wish to redirect non-logged in visitors to a "coming soon" page; but I have to make sure that I'm not throwing them into the dreaded "redirect loop", so I need to exclude the "coming soon" page from this rule:
global $pagenow;
if (
! is_admin() &&
'wp-login.php' != $pagenow &&
'coming-soon' != trim( $_SERVER["REQUEST_URI"] , '/' ) &&
! is_user_logged_in()
){
wp_safe_redirect( 'coming-soon' );
}
I believe that the Roots starter theme has a fantastic function to get the current page title. It is very hackable, covers all bases, and can be easily used with the wp_title hook.
/**
* Page titles
*/
function roots_title() {
if (is_home()) {
if (get_option('page_for_posts', true)) {
echo get_the_title(get_option('page_for_posts', true));
} else {
_e('Latest Posts', 'roots');
}
} elseif (is_archive()) {
$term = get_term_by('slug', get_query_var('term'), get_query_var('taxonomy'));
if ($term) {
echo $term->name;
} elseif (is_post_type_archive()) {
echo get_queried_object()->labels->name;
} elseif (is_day()) {
printf(__('Daily Archives: %s', 'roots'), get_the_date());
} elseif (is_month()) {
printf(__('Monthly Archives: %s', 'roots'), get_the_date('F Y'));
} elseif (is_year()) {
printf(__('Yearly Archives: %s', 'roots'), get_the_date('Y'));
} elseif (is_author()) {
$author = get_queried_object();
printf(__('Author Archives: %s', 'roots'), $author->display_name);
} else {
single_cat_title();
}
} elseif (is_search()) {
printf(__('Search Results for %s', 'roots'), get_search_query());
} elseif (is_404()) {
_e('Not Found', 'roots');
} else {
the_title();
}
}
Try this:
$pagename = get_query_var('pagename');
I have come up with a simpler solution.
Get the returned value of the page name from wp_title(). If empty, print homepage name, otherwise echo the wp_title() value.
<?php $title = wp_title('', false); ?>
Remember to remove the separation with the first argument and then set display to false to use as an input to the variable. Then just bung the code between your heading, etc. tags.
<?php if ( $title == "" ) : echo "Home"; else : echo $title; endif; ?>
It worked a treat for me and ensuring that the first is declared in the section where you wish to extract the $title, this can be tuned to return different variables.
Use:
$title = get_the_title($post);
$parent_title = get_the_title($post->post_parent);
echo $title;
echo $parent_title;
This seems to be the easiest to use:
<?php single_post_title(); ?>
One option, if you're looking for the actual queried page, rather than the page ID or slug is to intercept the query:
add_action('parse_request', 'show_query', 10, 1);
Within your function, you have access to the $wp object and you can get either the pagename or the post name with:
function show_query($wp){
if ( ! is_admin() ){ // heck we don't need the admin pages
echo $wp->query_vars['pagename'];
echo $wp->query_vars['name'];
}
}
If, on the other hand, you really need the post data, the first place to get it (and arguably in this context, the best) is:
add_action('wp', 'show_page_name', 10, 1);
function show_page_name($wp){
if ( ! is_admin() ){
global $post;
echo $post->ID, " : ", $post->post_name;
}
}
Finally, I realize this probably wasn't the OP's question, but if you're looking for the Admin page name, use the global $pagenow.
Within the WordPress Loop:
if ( have_posts() ) : while ( have_posts() ) : the_post();
/******************************************/
echo get_the_title();
/******************************************/
endwhile; endif;
This will show you the current page title.
For reference: get_the_title()
Here's my version:
$title = ucwords(str_replace('-', ' ', get_query_var('pagename')));
get_query_var('pagename') was just giving me the page slug. So the above replaces all the dashes, and makes the first letter of each word uppercase - so it can actually be used as a title.
Show the title before the loop starts:
$page_title = $wp_query->post->post_title;
This is what I ended up using, as of 2018:
<section id="top-<?=(is_front_page() ? 'home' : basename(get_permalink()));?>">
I've now found this function on WordPress Codec,
get queried
which is a wrapper for $wp_query->get_queried_object.
This post put me in the right direction, but it seems that it needs this update.
This also works if you are in the functions.php. It is not the best approach since you have to use the global array, but it works.
First, we need to add a filter. There must exist a better filter to use than the template_include, but I don't know all of them. Please point me to the right one.
add_filter( 'template_include', 'var_template_include', 1000 );
function var_template_include( $template ){
global $wp_query;
$GLOBALS['current_page'] = $wp_query->get_queried_object()->post_name;
return $template;
}
Avoid using the variable directly
function get_current_page( $echo = false ) {
if( !isset( $GLOBALS['current_page'] ) )
return false;
return $GLOBALS['current_page'];
}
Now you can use the function get_current_page() in any other part of the functions.php.
