# PHP Warning: Undefined array key “value” in lib-widget-fields.php

 * **Title:** PHP Warning: Undefined array key “value” in `lib-widget-fields.php`(
   checkbox widget field)
 * **Plugin version:** 8.8.7
 * **Environment:**
    - PHP 8.3 (CloudLinux Alt-PHP)
    - WordPress (latest)
 * **Description:**
 * The `checkbox()` method in `includes/widgets/lib-widget-fields.php` (line 85)
   reads `$field['value']` directly without checking whether the key exists:
 * php
 *     ```wp-block-code
       protected static function checkbox( $id, $name, $value, $label, $options, $field ) {
           ?>
           <input type="checkbox" ... value="<?php echo esc_attr( $field['value'] ); ?>" <?php checked( $value, $field['value'] ); ?> />
       ```
   
 * However, several built-in widgets define checkbox-type fields **without** setting
   a `'value'` key, e.g.:
    - `includes/widgets/popular-listings.php`
    - `includes/widgets/submit-listing.php`
    - `includes/widgets/login-form.php`
    - `includes/widgets/featured-listing.php`
    - `includes/widgets/all-locations.php`
 * Whenever one of these widgets is rendered in the WordPress admin (widget editor/
   Customizer), it throws:
 *     ```wp-block-code
       PHP Warning: Undefined array key "value" in .../includes/widgets/lib-widget-fields.php on line 85
       ```
   
 * This occurred 40 times in our error log over roughly a week of normal admin usage.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-warning-undefined-array-key-value-in-lib-widget-fields-php%2F%3Foutput_format%3Dmd&locale=en_US)
