Conditionally display featured image on singular posts and pages

Description

Important notice

If your theme does a customized call to load the featured image (like the Twenty Seventeen theme), this plugin might not work! Use get_the_post_thumbnail(), wp_get_attachment_image() or the Post Featured Image block to be sure it will work.
By default, the plugin also only hides the featured image, if it is loaded within the loop. See the FAQ on how to use the plugin if you theme loads the featured image outside the loop.

Description

This plugin lets you choose for each post or page, if the featured image should be shown in the single view. This can get handy, if you use the featured image to show a thumbnail on the archives or front page but you don’t want the featured image to be shown on every posts view itself.

The plugin adds a simple checkbox to the featured image panel (or meta box if you are using the classic editor), that lets you choose, if the featured image will be shown in the singular view or not.

Screenshots

Installation

1. Upload the plugin files to the /wp-content/plugins/conditional-featured-image directory, or install the plugin through the WordPress plugins screen directly.
2. Activate the plugin through the Plugins screen in WordPress

FAQ

The plugin doesn’t work with my theme. What can I do?

Typically there are two possibilities why the plugin is not compatible with your theme:

1) The theme loads the featured image before the loop (e.g. in the header).
2) The theme makes a custom call to load the featured image.

In case 1 you can initialize the plugin early and disable the in_the_loop check. To do so, add the following snippet to your functions.php:

function cybocfi_set_startup_hook() {
    return 'get_header';
}

add_filter( 'cybocfi_startup_hook', 'cybocfi_set_startup_hook' );
add_filter( 'cybocfi_only_hide_in_the_loop', '__return_false' );

Be aware, that this might have some side effects: e.g. it might also hide the featured image from plugins that would normally see it, like SEO plugins or the ‘latest posts’ plugin.

In case 2 either

• kindly ask the theme developer to use one of the dedicated WordPress functions (wp_get_attachment_image(), get_the_post_thumbnail(), the_post_thumbnail()) to load the featured image in the singular views.
• or create a child theme that replaces the call, that loads the featured image, with one of the methods listed above.

Is this plugin GDPR compliant?

This plugin does not process or store any personal information. Hence, it is fully GDPR compliant without any further ado.

Can I hide featured images by default?

Yes. Just add the following line to your functions.php:

add_filter('cybocfi_hide_by_default', '__return_true');

All new posts and pages will now hide the featured image by default (checkbox is checked by default). Existing posts and pages won’t be changed.

You may also set different default values depending on the post type:

function cybocfi_set_default_hiding_state( $default, $post_type ) {
    if ( 'post' === $post_type ) {
        $default = true; // set the default state for posts
    } else if ( 'page' === $post_type ) {
        $default = false; // set the default state for pages
    }

    return $default;
}
add_filter( 'cybocfi_hide_by_default', 'cybocfi_set_default_hiding_state', 10, 2 );

Can I limit this plugin to posts (and exclude other post types)?

Yes. By default, the plugin is available on any post type, that has a featured image. But there is a filter, that lets you control, for which post types the plugin should be available. The following example disables it for anything except for posts:

function cybocfi_limit_to_posts( $enabled, $post_type ) {
    if ( 'post' === $post_type ) {
        return $enabled;
    }

    return false;
}
add_filter( 'cybocfi_enabled_for_post_type', 'cybocfi_limit_to_posts', 10, 2 );

The filter provides you the current post type and you can decide if you want to use the plugin for this post type by returning true to enable and false to disable it. Add the following snippet to your functions.php to enable the plugin for posts and pages, but disable it for any other post type:

function cybocfi_limit_to_posts_and_pages( $enabled, $post_type ) {
    $allowed_post_types = array( 'post', 'page' ); // add any post type you want to use the plugin with
    return in_array( $post_type, $allowed_post_types );
}
add_filter( 'cybocfi_enabled_for_post_type', 'cybocfi_limit_to_posts_and_pages', 10, 2 );

Is it possible to get the plugin in my language?

Absolutely. You’re invited to contribute a translation in your language. Please keep in mind, that the translation needs to be reviewed by the community, so it will take a little while until it gets accepted.

How can I change the text of the checkbox?

There is a filter hook for this. Add the following snippet to your functions.php:

function cybocfi_set_featured_image_label( $label ) {
    return 'Hide featured image in post'; // change this string
}
add_filter( 'cibocfi_checkbox_label', 'cybocfi_set_featured_image_label' );

I can’t save posts in WordPress 5.7.0

A bug in WordPress core #52787 may render this plugin unusable if a second plugin uses post meta values in a certain way. People who are affected by this problem see the following error message “Updating failed. Could not delete meta value from database.”. As the issue is related to WordPress core the workaround is to downgrade to WordPress 5.6.2 or to upgrade to WordPress 5.7.1. To our current knowledge, only very few users are affected by this defect. The Conditionally display featured image on singular posts and pages plugin itself works as expected for WordPress 5.7.0 and the issue may only appear if a second plugin triggers the bug in WordPress core.

I’m getting a deprecation notice, what must I do?

The cybocfi_post_type filter was deprecated in favor of cybocfi_enabled_for_post_type, as the filter arguments were used in an unusual way. Transitioning from the former to the latter is easy. Here an example:

// Using the deprecated filter - REMOVE THIS CALL
function cybocfi_limit_to_posts( $post_type, $enabled ) {
    if ( 'post' === $post_type ) {
        return $enabled;
    }

    return false;
}
add_filter( 'cybocfi_post_type', 'cybocfi_limit_to_posts', 10, 2 );

// Using the new filter - THIS IS HOW IT SHOULD BE DONE NOW
function cybocfi_limit_to_posts( $enabled, $post_type ) {
    if ( 'post' === $post_type ) {
        return $enabled;
    }

    return false;
}
add_filter( 'cybocfi_enabled_for_post_type', 'cybocfi_limit_to_posts', 10, 2 );

All you’ve got to do is:

1) Change the filter hook from cybocfi_post_type to cybocfi_enabled_for_post_type.
2) Swap the filter functions arguments. $enabled is now the first argument $post_type the second.

In case you’ve only used one argument ($post_type), you must not only adapt the function signature, but also add the priority and number of arguments to your add_filter() function call. Just as it is shown in the example above.

Worked when CSS didn’t

MBV August 20, 2024 1 reply

For some reason, CSS to hide featured image wasn’t working, this plugin did the trick… Thanks so much!

Works fine on WordPress 6.6

stephunique July 23, 2024 1 reply

Plug and play, straight forward, just works. Works on Wordpress 6.6, maybe it doesn’t need to be updated that often. Thank you for such a simple fix to a niche request!

So relieved

kjc1900 April 6, 2024

Finally. A plug-in that just works. Thank you for making my headache go away.

Не везде работает

В некоторых темах просто не работает совсем. Галочку ставишь — эффекта нуль.

Doesn’t work any more – no updates in 4 months

Doesn’t work any more. Too bad – this is a needed function, but I’m uninstalling and looking for a different way.

Doesn’t Work If You Want Featured Image Hidden On Page, But Appearing in Social

marshallajonesjr September 19, 2023

Doesn’t Work If You Want Featured Image Hidden On Page, But Appearing in Social. I downloaded “Conditionally display featured image on singular posts and pages” because I need featured images to show up in Facebook posts but not on the page when it’s viewed in its own window. This plugin does NOT accomplish this. Maybe it does something else, but the description led me to believe it would do this Waste of time! The search for a solution continues …
