I have created a small wordpress plugin that displays a list of people in a page via shortcode.
When the user clicks on one of the names from the list, a query_var gets set and my plugin catches the $_GET with the specific id of the person the user just clicked. All very well until now.
My problem is that now I want to display a page with the details (for the clicked element) but I dont seem to be able to edit the content or post that gets to the page and it returns me to the page with the list of people.
My question is how do I edit the post? I have tried adding a add_filter('the_content','my_func') to this, but this does not work since this hook is probably already passed.
I can access the post directly via get_content() or get_post(), but I dont seem to be able to make the page populated new data.
In other words... this does nore seem to work
$fid = $_GET['fid'];
global $wpdb;
$sql = "select * from fighters where fighter_id = {$fid} limit 1";
$fighter = $wpdb->get_row($sql);
$html = $this->_getFighterPageLayout($fighter);
$post = get_post();
$post->post_content = $html;
$post->title = 'test';
$post->private = false;
// or even just global $content = $html;
What am I doing wrong and what ways do I have to edit/update the content/post?
You have to use the hooks of Wordpress to update the content. This works with the add_filter function
Try something like this, it should works
function mytheme_content_filter( $content ) {
// Do stuff to $content, which contains the_content()
// Then return it
return $content;
}
add_filter( 'the_content', 'mytheme_content_filter' );

I must to add new options and functions in post pages in admin panel. I call a new function in edit-form-advanced.php and edded this function in template.php file. The question is this wrong? Becouse my function is in one file with functions on wordpress. Or maybe must be in other file? but where i must call it?
For wp-content part i know and i make a child theme of parent theme, but i do not know what to do when i must add code in wp-admin part.
example:
edit-form-advanced.php
do_custom_boxes( null, $post );
and in template.php
function do_custom_boxes( $screen, $object ) {
global $wpdb;
$appTable = $wpdb->prefix . "post_panel";
$query = $wpdb->prepare("SELECT * FROM $appTable WHERE post_id = ".$_GET['post']." ", $screen);
$applications = $wpdb->get_results($query);
......
}
Short answer: Yes, it's wrong to do so. Whenever you update your WordPress you'll loose all your changes.
WordPress allows you to hook into its code, modify its behavior and many things.
Please read about actions and filters.
Basically, Actions allow you to fire a function when something happens in WordPress.
For example:
<?php
function do_something_when_admin_pages_init() {
// Do something here
}
add_action('admin_init', 'do_something_when_admin_pages_init')
Filters allow you to modify data/output of another function. It's like it let you step in the middle, do something with the data and then continue.
Example from the WordPress page:
<?php
function wporg_filter_title($title) {
return 'The ' . $title . ' was filtered';
}
add_filter('the_title', 'wporg_filter_title');
This modifies the title before it's printed.
So with those two ways of 'hooking' into the WordPress code, you can write your code in your theme's functions.php file, or write a Plugin (it's up to you).
I am currently creating a widget to display the registration form on a WordPress website that uses WooCommerce. For now, I only have 3 basic fields which are email, password, repeat password. I'm looking forward to add more WooCommerce fields, but want to solve that problem before jumping to the next step.
I'm having some problems with the messages output (wrong password, account already exists, etc).
I searched on the web and there was no shortcode already built for WooCommerce registration, beside their registration page. So I went ahead and created a shortcode, with a template part.
function custom_register_shortcode( $atts, $content ){
global $woocommerce;
$form = load_template_part('framework/views/register-form');
return $form;
}
add_shortcode( 'register', 'custom_register_shortcode' );
This is a snippet I use to get the template part inside a variable, since the default function would "echo" the content instead of "returning" it.
function load_template_part($template_name, $part_name=null) {
ob_start();
get_template_part($template_name, $part_name);
$var = ob_get_contents();
ob_end_clean();
return $var;
}
So, the problem is, when I call woocommerce_show_messages or $woocommerce->show_messages(); from my template part, nothing is showing, or if it is, it shows at the top of the page.
I did try to put the calls inside my shortcode function:
function custom_register_shortcode( $atts, $content ){
global $woocommerce;
$woocommerce->show_messages();
$form = load_template_part('framework/views/register-form');
return $form;
}
add_shortcode( 'register', 'custom_register_shortcode' );
Doing so, the message output inside the <head> tag, which is not what I want.
I tried to do the same trick with ob_start(), ob_get_contents() and ob_clean() but nothing would show. The variable would be empty.
I also did try to hook the woocommerce_show_messages to an action as saw in the core:
add_action( 'woocommerce_before_shop_loop', 'woocommerce_show_messages', 10 );
For something like:
add_action( 'before_registration_form', 'woocommerce_show_messages');
And I added this in my template-part:
<?php do_action('before_registration_form'); ?>
But I still can't manage to get the error messages show inside the box. It would always be inserted in the <head>
I will share final solution when everything is done.
Thanks for your time,
Julien
I finally got this working by hooking a custom function to an action which is called in my header.php
I guess hooking functions inside template part does not work as intended.
In header.php, I got this:
do_action('theme_after_header');
And here's the hooked function. Works perfectly.
function theme_show_messages(){
woocommerce_show_messages();
}
add_action('theme_after_header', 'theme_show_messages');
However, I will look into 'unhooking' the original show message function since it might show twice. Need to test some more ;)
You can also just use the [woocommerce_messages] shortcode in your template where you want it displayed
Replying to a bit of an old question, but you can also try the following:
$message = apply_filters( 'woocommerce_my_account_message', '' );
if ( ! empty( $message ) ) {
wc_add_notice( $message );
}
i'm working on a plugin that adds another parameter to feeds, i want to add a numberOfItems on the url and the feed returns that number of articles. I dont want to use the builtin option from WP Admin because the feed will be added on other websites with different number of items, it's a little bit complicated, the point is i need this implementation. i've added something like
function _my_custom_option( $option )
{
global $wp_query, $wp_rewrite;;
remove_filter( 'pre_option_posts_per_rss', '_my_custom_option' );
//$number = get_query_var('number');
$number = $wp_query->query_vars['numberOfItems'];
if(isset($number))
$option = $number;
else
$option = 10;
//$wp_rewrite->flush_rules();
add_filter( 'pre_option_posts_per_rss', '_my_custom_option' );
return $option;
}
add_filter( 'pre_option_posts_per_rss', '_my_custom_option' );
It seems that the feed is cached somehow and doesnt generate with the number of items, because when i add paged=2, it works. But if i change on page=2 numberOfItems with another number, it doesnt change. Plus, i added some junk text in wp-includes >feed-rss2.php just to verify if it cached or not. And it doesnt show after the first 2-3 page refreshes.
To be honest, i'm stuck, i don't know how to approach this, i've looked on the wordpress code and i dont see where the caching is done.
What about this?
function do_not_cache_feeds(&$feed) {
$feed->enable_cache(false);
}
add_action( 'wp_feed_options', 'do_not_cache_feeds' );
I'm trying to run a do_shortcode in functions.php with no luck
I'm using Types plugin http://wp-types.com/ for creating custom post types and custom fields.
What I'm trying do is adding a custom column in admin for view all custom posts that displays a thumbnail from a custom field.
This is what I got so far, but it seems that the shortcode doesn't work inside functions.php
// add a column for custom post type (products)
add_filter('manage_product_posts_columns', 'add_thumbnail_column');
add_action('manage_product_posts_custom_column', 'add_thumbnail_content', 10, 2);
function add_thumbnail_column($defaults)
{
$newSlice = array('thumbnail' => 'Image preview');
$counter = 2;
$array_head = array_slice($defaults,0,$counter);
$array_tail = array_slice($defaults,$counter);
$defaults = array_merge($array_head, $newSlice);
$defaults = array_merge($defaults, $array_tail);
return $defaults;
}
function add_thumbnail_content($column_name, $post_ID)
{
// this one works when putting into post content
echo do_shortcode('[types field="square-picture" id="' . $post_ID . '" size="thumbnail"]' . '[/types]');
}
Can anyone help please?
In the Wordpress notes for the function it says
"If there are no shortcode tags defined, then the content will be
returned without any filtering. This might cause issues if a plugin is
disabled as its shortcode will still show up in the post or content."
Types may be conditionally declaring their short code only when you are on the frontend. What may be happening is that, in the admin, the short code is not defined and you are simply getting a false return. While on the frontend, the shortcode is defined and you get the results you intended.
I am trying to run the following function anytime a wordpress "Jobs" custom post is published. The code works (lines 2-7) when it is placed in my theme template, but it only runs when the post is viewed. I want the code to run when the post is published, and so I have tried adding the code in a function inside my functions.php, but nothing is happening when each custom post is published. Any suggestions?
function indeedgeo(){
$indeedgeo = get_post_meta($post>ID, indeedgeo, true);
$indeedgeos=explode(' ',$indeedgeo);
$_jr_geo_latitude = $indeedgeos[0];
$_jr_geo_longitude = $indeedgeos[1];
update_post_meta($post->ID, _jr_geo_latitude, $_jr_geo_latitude);
update_post_meta($post->ID, _jr_geo_longitude, $_jr_geo_longitude);
}
add_action('publish_Jobs', 'indeedgeo');
You should hook into one of the three actions;
do_action('edit_post', $post_id, $post);
do_action('save_post', $post_id, $post);
do_action('wp_insert_post', $post_id, $post);
that are run when a post is either saved, or has its status updated. Something like the following should do the trick.
function se_10441543_save_post($post_id, $post){
//determine post type
if(get_post_type( $post_id ) == 'your_post_type'){
//run your code
$indeedgeo = get_post_meta($post_id, indeedgeo, true);
$indeedgeos=explode(' ',$indeedgeo);
$_jr_geo_latitude = $indeedgeos[0];
$_jr_geo_longitude = $indeedgeos[1];
update_post_meta($post_id, _jr_geo_latitude, $_jr_geo_latitude);
update_post_meta($post_id, _jr_geo_longitude, $_jr_geo_longitude);
}
}
add_action('save_post', 'se_10441543_save_post', 10, 2);

Not exactly sure how your "publish_jobs" hook is working but right off the bat, if you are placing this function in your functions.php, you will need to give it context. Replace $post>ID with the post number (an integer). If this applies to many post you will probably want to use another method of querying post data: http://codex.wordpress.org/Class_Reference/WP_Query. Let me know if this helps.
