Meta Box

Hi peter,

It could be obtained with get_options().
Thank you for sharing this information.

It would be helpful if you could also mention in the document that rwmb_meta() is not available in callback.

Thanks again.

Hi Peter,

The test code is as follows

What we want to achieve
* Generate the contents of the checkbox list in the callback of test_B depending on the status of the checkbox in test_A.

Defects
* When the value of test_A is retrieved in the callback of test_B, it is always false as well.

<?php
add_filter( 'rwmb_meta_boxes', 'example' );

function example( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'          => __( 'test field group', 'example-domain' ),
        'id'             => 'test1',
        'settings_pages' => ['custom-options'],
        'fields'         => [
            [
                'name'              => __( 'test A', 'example-domain' ),
                'id'                => $prefix . 'test_a',
                'type'              => 'checkbox',
                'std'               => false,
                'required'          => false,
                'clone'             => false,
                'clone_empty_start' => false,
            ],
            [
                'name'              => __( 'test B', 'example-domain' ),
                'id'                => $prefix . 'test_b',
                'type'              => 'checkbox_list',
                'options'           => test_function(),
                'inline'            => false,
                'select_all_none'   => false,
                'required'          => false,
                'clone'             => false,
                'clone_empty_start' => false,
            ],
        ],
    ];

    return $meta_boxes;
}

function test_function() {
	$value_a = rwmb_meta( 'test_A', array( 'object_type' => 'setting' ), 'custom-options' );

	$optionsA = array(
		'1' => 'Apple',
		'2' => 'Orange'
	);

	$optionsB = array(
		'3' => 'Cat',
		'4' => 'Dog'
	);

	return $value_a ? $optionsA : $optionsB;
}

Hi Peter,

I would like to use the standard WordPress functionality of controlling automatic plugin updates.
It is costly for an administrator to go to the trouble of putting in third party management plugins and setting up auto-updates for lots of plugins on many websites.

I think the auto-update feature in the WordPress plugin list is very easy to use....

Hi,

One correction.
Metabox itself is operating with automatic updates stopped.

Hi,

I looked up the compatibility behavior in PHP7 and found Symphony's polyfill.
https://github.com/symfony/polyfill

I was able to load this in wp-config and get it to work successfully.
WordPress core also uses str_contains() etc., but polyfill is provided.

It would be helpful if the plugin could be complemented with polyfill when using PHP8 functions.
Is it possible that the problem is that the Metabox itself is still out of date and only the MB extension has been upgraded?

Hi Peter,

Now that I understand your detailed advice, I will try with the enqueue function for the metabox field.

Thanks and regards,
Yumikom
