Remove specific shortcode from get_the_content()

Question

I have a variable like this:

$post_content = get_the_content();

Here I want to remove some specific shortcode from the $post_content variable e.g I want to remove only this [video height="300" width="300" mp4="localhost.com/video.mp4"] all other shortcodes and content formatting should be leaved intact.

How could this be done?

UPDATE:

I'm able to remove some specific shortcode by using code something like this ...

<?php 
    echo do_shortcode( 
        str_replace(
            '[video height="300" width="300" mp4="localhost.com/video.mp4"]', 
            '', 
            get_the_content()
        ) 
    ); 
?>

But it is also removing all html tags/formatting of get_the_content(). How to avoid it?

Answer 1

If you want exactly this shortcode:

[video height="300" width="300" mp4="localhost.com/video.mp4"]

to output nothing, then you can use the wp_video_shortcode_override filter or the wp_video_shortcode filter to achieve that.

Here are two such examples:

Example #1

/**
 * Let the [video] shortcode output "almost" nothing (just a single space) for specific attributes
 */
add_filter( 'wp_video_shortcode_override', function ( $output, $attr, $content, $instance )
{  
    // Match specific attributes and values
    if( 
          isset( $atts['height'] ) 
        && 300 == $atts['height'] 
        && isset( $atts['width'] ) 
        && 400 == $atts['width'] 
        && isset( $atts['mp4'] )
        && 'localhost.com/video.mp4' == $atts['mp4']   
    )
        $output = ' '; // Must not be empty to override the output

    return $output;
}, 10, 4 );

Example #2

/**
 * Let the [video] shortcode output nothing for specific attributes
 */
add_filter( 'wp_video_shortcode', function( $output, $atts, $video, $post_id, $library )
{
    // Match specific attributes and values
    if( 
          isset( $atts['height'] ) 
        && 300 == $atts['height'] 
        && isset( $atts['width'] ) 
        && 400 == $atts['width'] 
        && isset( $atts['mp4'] )
        && 'localhost.com/video.mp4' == $atts['mp4']   
    )
        $output = '';

    return $output;
}, 10, 5 );

Note

I would recommend the first example, because there we are intercepting it early on and don't need to run all the code within the shortcode callback.

Answer 2

You can use php preg_replace core function to search for your shortcode in content and remove it so your code may be :

$post_content_without_shortcodes = preg_replace ( '/\[video(.*?)\]/s' , '' , get_the_content() );

Answer 3

Wouldn't it be

$post_content_without_shortcodes = strip_shortcodes(get_the_content());

or there's also

$post_content_without_shortcodes = remove_all_shortcodes(get_the_content());
