I am using get_the_content() to load other pages content on the current page, and I noticed some block CSS classes are missing in the HTML I get.

For example, is-layout-flex layout CSS class is missing for the Columns block, which is causing block to look different from how it looks when the page is open normally, in a browser tab.

When I open page normally, in a browser tab I get this:
<div class="is-layout-flex wp-container-7 wp-block-columns">

But, when I get the content of the page with the get_the_content(), I get this:
<div class="wp-block-columns">

Is there a way to make get_the_content() provide exactly the same content as it is provided when the page is open normally, in a browser tab?

  • Actually, why don't you just use the_content()? Why must get_the_content()? Because it will return the raw block HTML with the block comment delimiters like <!-- wp:columns -->.

  • Sorry for delayed answer Sally, Honestly I was not quite sure about the difference between them. I could use the_content() as well.

    In that case, then you should probably just use the_content(), unless if you don't want the filters like mentioned here (and many other filters) to be applied, which also means you'd need to manually apply the do_blocks() to ensure blocks are parsed properly (e.g. specific CSS classes are added).

    It should also be noted that get_the_content() returns the content, whereas the_content() displays (i.e. echo) the content. But the_content() is not simply a shorthand/wrapper for echo get_the_content().

You can achieve that by applying the the_content filters, just like what the_content() does:

$content = get_the_content();
$content = apply_filters( 'the_content', $content );
$content = str_replace( ']]>', ']]&gt;', $content );

echo $content;

Or the other way is by applying do_blocks() on the content:

$content = get_the_content();
$content = do_blocks( $content );

echo $content;

    Thank you! do_blocks() is what I need.
