get_the_content() WP 0.71

Gets the content of the current post. Must be used inside the WordPress loop.

Does not filter content as the_content() does. Therefore, if you want to get the result by applying all the_content hooks to the content, use this construction:

apply_filters( 'the_content', get_the_content() );

Return

String. Post content.

Usage

$content = get_the_content( $more_link_text, $strip_teaser );

$more_link_text(string)

The text of the "read more" link. This link is added when the post content has html comment <!--more--> and when this function uses on any archive page (not single page).
Default: null

$strip_teaser(true/false)

Do we need strip content before the <!--more--> tag when the content is shown on singular page. The word "teaser" means attractive text before the <!--more--> tag.

By default this parameter is disabled. It can also be enabled by specifying anywhere in the post content <!--noteaser--> html comment (usually, it specified immediately after the <!--more-->).
Default: false

$post(WP_Post/object/int) (since 5.2)

Post, content of which we need to get.
Default: null

Examples

#1 Get the content of the post

Output the content of the post with the link "read more" where necessary:

<?php
$content = get_the_content('read more');
echo apply_filters( 'the_content', $content );
?>

Notes

• Global. Int. $page Page number of a single post/page.
• Global. Int. $more Boolean indicator for whether single post/page is being viewed.
• Global. true|false. $preview Whether post/page is in preview mode.
• Global. Array. $pages Array of all pages in post/page. Each array element contains part of the content separated by the <!--nextpage--> tag.
• Global. Int. $multipage Boolean indicator for whether multiple pages are in play.
