# [BUG Report] ‘reference’ shortcode

* [2 years, 6 months ago](https://wordpress.org/support/topic/bug-report-reference-shortcode/)
* ```wp-block-code
easydocs/shortcodes/reference.php
```
* I’m using EasyDocs Pro version, and had some issues after installing the plugin
* Finally found the code from above file
* ‘the_content’ filter applied to all posts on site without ‘reference’ shortcode
🙁
* And the filter applied with closure function and even developer cannot exclude
that filter
* The code should applied ONLY when the ‘reference’ code is included and the filter
function must have function name not closure!!
* ```wp-block-code
if( !has_shortcode( $ezd_content, 'reference' ) ) {
return $ezd_content;
}
```

* This issue still not fixed after 5 months 🙁
* The code below is having a huge impact on the site’s performance!
* It filters all content of all post types and do all shortcodes to that contents(`
easydocs/shortcodes/reference.php`)
* ```wp-block-code
add_filter( 'the_content', function ( $ezd_content ) {
$ezd_options = get_option( 'eazydocs_settings' );
$is_notes_title = $ezd_options['is_footnotes_heading'] ?? '1';
$notes_title_text = $ezd_options['footnotes_heading_text'] ?? __( 'Footnotes', 'eazydocs' );
$footnotes_column = $ezd_options['footnotes_column'] ?? '1';
$all_shortcodes = ezd_all_shortcodes( $ezd_content );
$all_shortcoded = '';
foreach ( $all_shortcodes as $all_shortcode ) {
$all_shortcoded .= '' . do_shortcode( $all_shortcode[0] ) . '';
}
$ezd_footnote_title = '';
if ( ! empty( $notes_title_text ) && $is_notes_title == '1' && has_shortcode( $ezd_content, 'reference' ) ) {
$ezd_footnote_title = sprintf( '', $notes_title_text );
}
$footnotes_contents = '';
if ( has_shortcode( $ezd_content, 'reference' ) ) {
$footnotes_contents = $ezd_footnote_title . "";
}
return $ezd_content . $footnotes_contents;
} );
```
* You should apply this filter to certain post types ONLY
* And ONLY when the content has ‘reference’ shortcode
* Or at least provide a function name so we can remove the filter.
* ```wp-block-code
function ezd_reference_content_filter($content) {
$types = apply_filters('ezd_xxxx', ['doc']);
if ( !in_array( get_post_type(), $types ) || !has_shortcode( $content, 'reference' ) ) {
return $content;
}
xxxxxx
xxxxxx
return $content;
}
add_filter( 'the_content', 'ezd_reference_content_filter' );
```
* Thanks in advance
