WordPress Get Page ID Outside of Loop

I want to get the page id before starting the loop in WordPress. I use

$page = get_query_var('page_id');

Apparently, nothing returns.

I just want to check the page for its identifier and add a class to the <body> based on it.

If you use fairly permalinks, get_query_var('page_id') will not work.

Instead, get the id of the requested object from the global $wp_query :

 // Since 3.1 - recommended! $page_object = get_queried_object(); $page_id = get_queried_object_id(); // "Dirty" pre 3.1 global $wp_query; $page_object = $wp_query->get_queried_object(); $page_id = $wp_query->get_queried_object_id();

You can also create a general function to get the message identifier, regardless of whether it is located outside or inside the loop (handles both cases):

 <?php /** * @uses WP_Query * @uses get_queried_object() * @see get_the_ID() * @return int */ function get_the_post_id() { if (in_the_loop()) { $post_id = get_the_ID(); } else { global $wp_query; $post_id = $wp_query->get_queried_object_id(); } return $post_id; } ?>

And just do:

 $page_id = get_the_post_id();

Use this global $ post instead:

 global $post; echo $post->ID;

If you were looking for this topic in any way because of the message page (alternate page page when using a static first page), then the correct answer is:

 if (get_option('show_on_front') == 'page') { $page_id = get_option('page_for_posts'); echo get_the_title($page_id); }

You can use is_page($page_id) outside the loop to check.

This function gets the identifier from the current page.

 get_the_ID();

Use below two lines of code to get the current page or message

 global $post; echo $post->ID;

If you are on the page and this does not work:

 $page_object = get_queried_object(); $page_id = get_queried_object_id();

you can try creating a permalink manually using PHP so that you can find the post id:

 // get or make permalink $url = !empty(get_the_permalink()) ? get_the_permalink() : (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; $permalink = strtok($url, '?'); // get post_id using url/permalink $post_id = url_to_postid($url); // want the post or postmeta? use get_post() or get_post_meta() $post = get_post($post_id); $postmeta = get_post_meta($post_id);

It may not catch all possible permalinks (especially since I delete the query string), but you can change it according to your use case.

I did it as follows and it worked perfectly for me.

First, they declared a global variable in header.php, assigning the identifier of the message or page before changing it, since LOOP assigns the identifier of the last record shown:

$GLOBALS['pageid] = $wp_query->get_queried_object_id();

And use anywhere in the template, for example, in the footer.php file:

echo $GLOBALS['pageid];

This is the correct code.

 echo $post->ID;

If you are not using WordPress Loop, you cannot use any wordpress method, so you should use pure php.

You can use this code. And they will definitely help you :)

 $page_id = @$_GET['page_id']; if (!is_numeric($page_id)) { // Then the uri must be in friendly format aka /my_domain/category/onepage/ // Try this //$path = '/www/public_html/index.php/'; ///$path = '/my_domain/category/onepage/'; $path = $_SERVER['REQUEST_URI']; // Clean the uri //$path = str_replace('/', '', $page); $path = str_replace('.php', '', $path); //$path = str_replace('?s=', '', $path); $path = $path ? $path : 'default'; $path_len = strlen($path); $last_char = substr($path, $path_len -1); //echo $last_char; $has_slash = strpos($last_char, "/"); //echo $has_slash; if ($has_slash === 0) : $path = substr($path, 0, $path_len -1); elseif ($has_slash === null) : $path = substr($path, 0, $path_len); endif; //echo "path: ".$path; // '/www/public_html/index' $page = substr(strrchr($path, "/"), 1); echo "page: ".$page; // 'index' } $my_page_id = 31; $my_page = 'mypage'; //echo "page: ".$page; //echo "page_id ".$page_id; if($page_id == $my_page_id || $page == $my_page) { // your stuff.... }

Enjoy it!
