ACF wysiwyg editor not rendering correctly

The ACF (Advanced Custom Fields) plugin is a popular tool for adding custom fields to your WordPress website. One of the field types provided by ACF is the WYSIWYG editor, which allows you to create rich text content with formatting options. However, sometimes the ACF WYSIWYG editor may not render correctly due to various reasons, such as conflicts with other plugins or themes.

To troubleshoot and fix the issue of the ACF WYSIWYG editor not rendering correctly, you can try the following steps:

1. Check for JavaScript errors: Open your browser’s developer console (usually accessed by right-clicking on the page and selecting “Inspect” or “Inspect Element”), and look for any JavaScript errors. These errors can sometimes interfere with the proper functioning of the editor. Resolve any JavaScript errors that you find.

2. Disable conflicting plugins or themes: Temporarily deactivate other plugins or switch to a default WordPress theme (e.g., Twenty Twenty-One) to see if the issue is caused by a conflict. If the editor works correctly after deactivating a specific plugin or theme, you can narrow down the conflict by reactivating them one by one until the issue reoccurs.

3. Increase PHP memory limit: In some cases, the ACF WYSIWYG editor may not render correctly due to insufficient PHP memory limit. You can try increasing the memory limit by adding the following code to your theme’s functions.php file:

define( 'WP_MEMORY_LIMIT', '256M' );

4. Check for ACF compatibility: Ensure that you are using the latest version of the ACF plugin and that it is compatible with your WordPress version. Check the ACF documentation or support forums for any known issues or compatibility problems.

5. Inspect ACF field settings: Double-check the settings of your ACF WYSIWYG field. Make sure you have configured it correctly, including any allowed formatting options, toolbar settings, or restrictions.

If none of the above steps resolve the issue, you may need to seek further assistance from the ACF support team or consider reaching out to a WordPress developer for more advanced troubleshooting.

Remember to always backup your website before making any changes to plugins, themes, or code.

Examples

Example 1: Fixing ACF WYSIWYG Editor Rendering Issue

This example demonstrates how to fix the issue of the Advanced Custom Fields (ACF) WYSIWYG editor not rendering correctly on the front-end of a WordPress website.

function wpsnippets_fix_acf_wysiwyg_editor() {
    add_filter('acf/format_value/type=wysiwyg', 'wpsnippets_fix_acf_wysiwyg_editor_output', 10, 3);
}

function wpsnippets_fix_acf_wysiwyg_editor_output($value, $post_id, $field) {
    return apply_filters('the_content', $value);
}

wpsnippets_fix_acf_wysiwyg_editor();

The code above fixes the issue by adding a filter to the acf/format_value/type=wysiwyg hook. It then applies the the_content filter to the value of the WYSIWYG field, ensuring that the content is rendered correctly on the front-end.

Example 2: Customizing ACF WYSIWYG Editor Toolbar

This example demonstrates how to customize the toolbar options of the ACF WYSIWYG editor.

function wpsnippets_customize_acf_wysiwyg_toolbar($toolbars) {
    $toolbars['Custom Toolbar'] = array();
    $toolbars['Custom Toolbar'][1] = array('bold', 'italic', 'underline');
    $toolbars['Custom Toolbar'][2] = array('link', 'unlink');
    $toolbars['Custom Toolbar'][3] = array('formatselect', 'styleselect', 'removeformat');
    return $toolbars;
}

add_filter('acf/fields/wysiwyg/toolbars', 'wpsnippets_customize_acf_wysiwyg_toolbar');

The code above adds a filter to the acf/fields/wysiwyg/toolbars hook and defines a custom toolbar named “Custom Toolbar”. It then specifies the buttons to be displayed in each row of the toolbar. In this example, the first row contains the bold, italic, and underline buttons, the second row contains the link and unlink buttons, and the third row contains the formatselect, styleselect, and removeformat buttons.

Example 3: Limiting ACF WYSIWYG Editor Word Count

This example demonstrates how to limit the word count of the ACF WYSIWYG editor to a specific number.

function wpsnippets_limit_acf_wysiwyg_word_count($value, $post_id, $field) {
    $word_limit = 100;
    $word_count = str_word_count(strip_tags($value));

    if ($word_count > $word_limit) {
        $value = wp_trim_words($value, $word_limit);
    }

    return $value;
}

add_filter('acf/format_value/type=wysiwyg', 'wpsnippets_limit_acf_wysiwyg_word_count', 10, 3);

The code above adds a filter to the acf/format_value/type=wysiwyg hook and defines a word limit of 100. It then counts the number of words in the WYSIWYG field value and uses wp_trim_words to trim the content if it exceeds the word limit. The trimmed content is then returned.
