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.

I'm using DIVI theme and have created a custom category layout. However, I can't seem to find a way to add the category description to the layout. DIVI doesn't provide any answers, and I've searched here as well. Can I use some tags to get it?
The code below almost works - I do get the text, but not linebreaks, even though they are present if I do a echo '<pre>'; print_r($cat); echo '</pre>';
add_shortcode('cat_desc', 'cat_desc_shortcode');
function cat_desc_shortcode() {
global $wp_query;
$cat = $wp_query->get_queried_object();
if( $cat == null ) return;
$output = '<div class="page-description"> '.$cat->description.' </div> ';
return $output;
}
Thanks
Got it working now. For others in the same situation, add this code to your functions.php file in your (child) theme.
add_shortcode('cat_desc', 'cat_desc_shortcode');
function cat_desc_shortcode() {
global $wp_query;
$cat = $wp_query->get_queried_object();
if( $cat == null ) return;
$output = nl2br($cat->description);
return $output;
}
Then use the shortcode [cat_desc] in your layout, where you would like the category description to appear. This at least works for me.
I am trying to relocate the position of the output generated by a review plugin for wordpress. The plugin hooks into the end of "the_content". I have found the filter which works to remove the output:
remove_filter('the_content', array( EDD_Reviews::get_instance(), 'load_frontend'));
Now I am going crazy trying to relocate the output to a new location. I have created a custom hook in my theme file:
function reviews() {
do_action('reviews');
}
The above hook outputs just fine to custom location in the theme files when passed a simple function. However the tricky part is getting the reviews and review form to display. I tried adding it back with this:
add_action('reviews', array( EDD_Reviews::get_instance(), 'load_frontend'));
This did not work. The full function I am trying to call is below. Any body have any ideas how I may call this via my new hook? I am rather stuck.
public function load_frontend( $content ) {
global $post;
if ( $post && $post->post_type == 'download' && is_singular( 'download' ) && is_main_query() && ! post_password_required() ) {
ob_start();
edd_get_template_part( 'reviews' );
if ( get_option( 'thread_comments' ) ) {
edd_get_template_part( 'reviews-reply' );
}
$content .= ob_get_contents();
ob_end_clean();
}
return $content;
}
Many thanks in advance.
Ok mostly figured this out after studying classes. If anyone else is looking to do this then remove the hook as below:
remove_filter('the_content', array( EDD_Reviews::get_instance(), 'load_frontend'));
The following line will then render the reviews and form anywhere you like:
<?php echo EDD_Reviews()->load_frontend( '' ); ?>
Is there a Wordpress function for grabbing the page attributes? I need to be able to check which templates are being used on which pages.
I have tried the get_post and get_pages but neither one outputs the page attributes.
Thanks in advance!
solution:
$ids= get_all_page_ids();
foreach ($ids as $id){
$meta = get_metadata('post', $id);
//var_dump($meta);
$template = $meta['_wp_page_template'][0];
echo $template;
echo "<br>";
}
Try using get_all_metadata. That will fetch all the meta records for a given object.
<?php
$post_id = 123;
$meta = get_metadata('post', $post_id);
echo $meta['my_custom_field_key'];
The docs are a good place to look: Function Reference « WordPress Codex
i.e.: Function Reference/get page template which
Displays the filename of the page template used to render a Page
(printed within an HTML comment, in this example) :
<?php echo '<!-- ' . basename( get_page_template() ) . ' -->'; ?>
And,
global $wp_query;
$template_name = get_post_meta( $wp_query->post->ID, '_wp_page_template', true );
will give you the template file name. Use str_replace() to strip the .php from the end.

Trying to get my post meta from posts using shrotcodes and then displaying it on the content.This is the code that's trying to do this:
$string = '';
$custom_content = get_post_custom($post->ID);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post();
$content = get_the_content();
$bonus = $custom_content["bonus"];
$string .= $content . $bonus . '<br>';
endwhile;
}
return $string;
It's not working as the custom content returns empty. Whats wrong? Thanks in advance
I don't think you got the shortcode idea, you should read some info about add_shortcode() also you can use get_post_meta() to retriev the metadata from the database.
Here is an example on how you can achieve this but this will only work with the main loop (as default):
<?php
//you can put this code in functions.php or you can build a plugin for it
function metadata_in_content($attr) {
//this is the function that will be triggerd when the code finds the proper shortcode in the content; $attr is the parameter passed throw the shortcode (leave null for now)
global $wpdb, $wp_query;
//we need global $wpdb to query the database and to get the curent post info
if (is_object($wp_query->post)) {
$post_id = $wp_query->post->post_id;// here we save the post id
$metadata = get_post_meta( $post_id, $key, $single ); // here we get the needed meta, make sure you place the correct $key here, also if you don't want to get an array as response pass $single as "true"
return $metadata; // this finally replaces the shortcode with it's value
}
}
add_shortcode('insert_metadata', 'metadata_in_content');
//the above code hooks the metadata_in_content function to the [insert_metadata] shortcode
?>
Now all it's left to do is to place [insert_metadata] in the post content and things should work.
I create category image thumbnails, here i want to which post have no images the post is exit(); .Here is my code for found post image, but how can exit the particular post that have dont image. plz specify me.
<?php //found the images from the post content
global $post, $posts;
$postContent = $post->post_content;
$searchimages = '~<img [^>]* />~';
preg_match_all( $searchimages, $postContent, $post_imgs );
// Check to see if we have at least 1 image
$findImages = count( $post_imgs[0] );
if ( $findImages > 0 ) {
echo "found"."<br />";
} else {
echo "not found"."<br />";
}
?>
Here i define the not found, but i want to this not found post is exit;
If by exit, you mean exiting out the braces (of an if/else statement), use a simple break; function.
