I am calling in content in Wordpress via the below code. Eseentially, I am dividing the content of the post into three sections; 1. Before the tag, 2. After the tag and 3. Post gallery. The code I have so far works perfectly to get the content, however I am having an issue as all formatting tags (p in particular) are being stripped. Is there a way to retain these?
Thanks
<?php
// Fetch post content
$content = get_post_field( 'post_content', get_the_ID() );
// Get content parts
$content_parts = get_extended( $content );
?>
<p>
<?php echo $content_parts['main']; // Output content before <!--more--> ?>
</p>
<p class="read-more">
<?php echo strip_shortcodes($content_parts['extended']); // Output content after <!--more--> ?>
</p>
<button>Read More</button>
<?php $gallery = get_post_gallery_images( $post ); ?>
When you pull the post content using get_post_field, the autop filter is not applied:

You can apply all of the content filters yourself by adding this line after you set $content:
$content = apply_filters('the_content', $content);

I have an array of posts from an WPQuery by doing
$query = new WPQuery(.....)
$array_of_posts = $query->post_content
However this is returning the content as HTML as with some other stuff too
<!-- wp:paragraph -->
<p>the text</p>
<!-- /wp:paragraph -->
And then i want to display this as content for each post in the array
foreach($array_of_posts as $post){
<h1> echo $post->post_content </h1>
But of course this just gives me a h1 with the html and other stuff. How can i just get the string?
Also this code is just pseudo code i know the syntax is wrong
You're looking wp_strip_all_tags()
Source # https://developer.wordpress.org/reference/functions/wp_strip_all_tags/
Properly strip all HTML tags including script and style. This differs from strip_tags() because it removes the contents of the <script> and <style> tags. E.g. strip_tags( '<script>something</script>' ) will return ‘something’. wp_strip_all_tags will return ‘’
echo wp_strip_all_tags( the_content() );
Alternatively , you could use remove_filter('term_description','wpautop'); in your function.php to remove the <p> tags.
I'm trying to make a custom RSS feed with some alteration to the HTML content of each post.
Inside the template file rss-custom.php I have this:
<?php while (have_posts()) : the_post(); ?>
<?php echo processPostContent(); ?>
<?php endwhile; ?>
in functions.php, there are three replacements as follows :
function processPostContent() {
$post = get_post(get_the_ID());
$post_content = strval($post->post_content);
// replace h3 and h4 tags with h2
$post_content = preg_replace('/<(\/?)h((?![12])\d)/im', "<$1h2", $post_content);
// strip every attribute of <img> other than src
$post_content = preg_replace('/<img[^>]*(src="[^"]*")[^>]*>/im', "<img $1 />", $post_content);
// insert text after some closing tags
$post_content = preg_replace('/<\/(h2|p|figure)>/im', "</$1><p>Inserted</p>", $post_content);
return $post_content;
}
Then I get a strange result: out of 20 posts, only 7-8 of them will have been fully replaced. The remaining get the first two replacements but not the third one. Does anyone know why that is?
The solution, turns out, doesn't have anything to do with the loop nor preg_replace. Some posts' contents do not include any HTML tag, only plain text. That's why preg_replace didn't have any effect on them. When those contents are rendered in the RSS feed, however, <p> tags are automatically inserted. That's what led me to believe the third replacement was skipped.
First paragraph.
Second paragraph.
is turned to
<p>First paragraph.</p>
<p>Second paragraph.</p>
I want to remove a div added by a plugin to the content of WordPress posts. So the post has this structure:
<div class="post">
<div class="some-class">
<p>content</p>
</div>
</div>
I want to remove <div class="some-class"> and its closing </div> but leave the content. So it would be:
<div class="post">
<p>content</p>
</div>
using this filter:
add_filter( 'the_content', 'remove_class' , 100 );
function remove_class( $content ) {
$content = preg_replace('#<div[^>]*class="some-class"[^>]*>.*?</div>#is', '', $content);
return $content;
}
the content is also deleted, I just want the div and the closing div to be deleted. Any idea how?
this question is not duplicate of the other question because I want to remove a specific div not just all divs
You could just try to remove class attribute, so that only <div> is left, using code like this:
add_filter( 'the_content', 'remove_class' , 100 );
function remove_class( $content ) {
$content = preg_replace('/class=".*?"/', '', $content);
return $content;
}
#user7592255 you can try with jQuery like this:
$('p').unwrap();
If you can set an id or class on the p element you can target it more accurately
The content is removed because you replace the entire matched string with an empty string. Use a subpattern to capture the content of the <div> element and use it as replacement:
$content = preg_replace(
'#<div[^>]*class="some-class"[^>]*>(.*?)</div>#is',
'$1',
$content
);
However, be aware that it won't work properly if the content of <div class="some-class"> contains a <div> element.
There is no way to parse HTML using regex. The correct solution is to use an HTML parser (DOMDocument f.e.) to parse the HTML fragment and create its DOM, then operate the changes on the DOM and render it back to HTML.
I wanted to remove the images from a WordPress post to give me more control of how I could layout the design for the front page of a website. After doing some messing around and failing, I finally found a great post which had an amazing little piece of code that solved my problem.
<?php
$content = get_the_content();
$postOutput = preg_replace('/<img[^>]+./','', $post->post_content);
echo $postOutput;
?>
But some time i have link above images like:
<img src="PATH_IMAGES">
So, How can remove it?
Change above code by following code which remove link if exist into your content.
$content = get_the_content();
$postOutput = preg_replace('/<img[^>]+./','', $post->post_content);
$postContent = preg_replace("/<a[^>]+\>/i", "", $postOutput);
echo $postContent;
I am printing out the content of a specific post (103 in this case) with the following code:
<?php $post_id = 103; $queried_post = get_post($post_id); echo apply_filters('the_content',$queried_post->post_content); ?>
How can I make it exclude all the html tags like <p> and <br>s, and just show the text?
Thanks!
Use strip_tag(string) function to remove all html tags from string
echo strip_tags(apply_filters('the_content',$queried_post->post_content));
