Hide Broken Shortcodes

Description

By default in WordPress, if the plugin that provides the functionality to handle any given shortcode is disabled, or if a shortcode is improperly defined in the content (such as with a typo), then the shortcode in question will appear on the site in its entirety, unprocessed by WordPress. At best this reveals unsightly code-like text to visitors and at worst can potentially expose information not intended to be seen by visitors.

This plugin prevents unhandled shortcodes from appearing in the content of a post or page. If the shortcode is of the self-closing variety, then the shortcode tag and its attributes are not displayed and nothing is shown in their place. If the shortcode is of the enclosing variety (an opening and closing tag bookend some text or markup), then the text that is being enclosed will be shown, but the shortcode tag and attributes that surround the text will not be displayed.

See the Filters section for more customization tips.

Developer Documentation

Developer documentation can be found in DEVELOPER-DOCS.md. That documentation covers the hooks provided by the plugin.

As an overview, these are the hooks provided by the plugin:

• hide_broken_shortcode : Customizes what, if anything, gets displayed when a broken shortcode is encountered.
• hide_broken_shortcodes_filters : Customizes what filters to hook to find text with potential broken shortcodes.

Installation

1. Install via the built-in WordPress plugin installer. Or install the plugin code inside the plugins directory for your site (typically /wp-content/plugins/).
2. Activate the plugin through the ‘Plugins’ admin menu in WordPress
3. Optionally filter ‘hide_broken_shortcode’ or ‘hide_broken_shortcodes_filters’ if you want to customize the behavior of the plugin

FAQ

Why am I still seeing a broken shortcode even with this plugin activated?

By default, the plugin only tries to hide broken shortcodes appearing in post/page content, post/page excerpts, and widgets. It does not hide broken shortcodes that may appear in post/page titles, custom fields, menus, comments, etc.

How can I type out a shortcode in a post so that it doesn’t get processed by WordPress or hidden by this plugin?

If you want want a shortcode to appear as-is in a post (for example, you are trying to provide an example of how to use a shortcode), can use the shortcode escaping syntax, which is built into WordPress, by using two opening brackets to start the shortcode, and two closing brackets to close the shortcode:

• [[some_shortcode]]
• [[an_example style="yes"]some text[/an_example]]

The shortcodes will appear in your post (but without the double brackets).

How can I prevent certain broken shortcodes from being hidden?

Assuming you want to allow the broken shortcodes ‘abc’ and ‘gallery’ to be ignored by this plugin (and therefore not hidden if broken), you can include the following in your theme’s functions.php file or in a site-specific plugin:

/**
 * Permit certain shortcodes to appear as broken without being hidden.
 *
 * @param string $display        The text to display in place of the broken shortcode.
 * @param string $shortcode_name The name of the shortcode.
 * @param array  $m              The regex match array for the shortcode.
 * @return string
 */
function allowed_broken_shortcodes( $display, $shortcode_name, $m ) {
    $shortcodes_not_to_hide = array( 'abc', 'gallery' );
    if ( in_array( $shortcode_name, $shortcodes_not_to_hide ) ) {
        $display = $m[0];
    }
    return $display;
}
add_filter( 'hide_broken_shortcode', 'allowed_broken_shortcodes', 10, 3 );

Does this plugin include unit tests?

Yes.

zakisp March 3, 2018

I installed the plugin but shortcode is still appearing The shortcode is a qtranslate language string documentation can be improved and maybe you can add troubleshooting section in the documentation or the reason why it might not work

Nice

Not flashy. Does one thing and does it right. If shortcode isn’t working, readers can’t see it.
