Meta Box

Hi,

Sorry, as I said above, I've just assigned the field group Event to (default) Post to re-check the issue. Now, assign it back to Event and the relationships still works as well, screen record https://monosnap.com/file/1QNR2s5GewCEbnRHzXWam0oT5dSMaz
So we can confirm it's not the problem with the PHP setting max_input_vars, I see you increase this value to 500k.

You can try to deactivate all plugins then activate them one-by-one to find the conflicting plugin.

Regarding the issue with the code on this topic https://support.metabox.io/topic/query-advanced-select-field-by-relationship/, please check it after resolving this issue. Just to make sure MB Relationships works properly.

Hi,

It looks like there is a conflict between MB Relationships and another plugin or a snippet code on your site. What I've done:
- Deactivate all plugins except Meta Box and MB AIO
- Assign the field group from Event to Post to avoid the issue with the setting max_input_vars (too many inputs when submitting)
- Disable other snippets in the Advanced Script board.

Hi,

I've used the plugin Health Check to temporarily deactivate all plugins except Meta Box and Meta Box AIO then I can save more connection items as well. Can you please re-check it?
wp-admin/post.php?post=122&action=edit

Hi,

You can use the filter rwmb_{$field_id}_value to modify the value of a specific field.
Or the action rwmb_{$field_id}_after_save_field to do something after saving a specific field.

Read more on the documentation

Hi,

Thanks for your additional information.

Looking in your screen record, I see there are many custom fields assigned to that post so I think increasing the setting max_input_vars to 10000 (10k) is not enough. Can you please increase a larger value (4-500k)?

And use this code to save more connection items, currently, the option query_args in the builder is not working correctly.

add_action( 'mb_relationships_init', 'ec_block1' );
function ec_block1() {
    MB_Relationships_API::register( [
        'id'   => 'event-to-course-relationship',
        'from' => [
            'object_type'   => 'post',
            'post_type'     => 'events',
            'empty_message' => 'Choose an event',
            'field'         => [
                'name'       => 'From Events to Courses',
                'query_args' => [
                    'number' => 50 // This
                ],
            ],
        ],
        'to'   => [
            'object_type'   => 'post',
            'post_type'     => 'course',
            'empty_message' => 'Choose a course',
            'field'         => [
                'name' => 'To Course from Events',
            ],
        ],
    ] );
}

Hi Mike,

Did you try to use the example code to update the field value stored in the custom table?
https://docs.metabox.io/rwmb-set-meta/#examples

add_action( 'init', function() {
	$table_name = 'my_table';
	$post_id = 123;
	$field_id = 'my_field';
	$value = 'My custom value';
	rwmb_set_meta( $post_id, $field_id, $value, [
		'storage_type' => 'custom_table',
		'table'        => $table_name,
	] );
}, 99 );

You can also use the public API of MB Custom Table to update field value as well.
https://docs.metabox.io/extensions/mb-custom-table/#api

$data = [
	'field_1' => 'value 1',
	'field_2' => 'value 2',
	'field 3' => ['one', 'two', 'three'],
];
\MetaBox\CustomTable\API::update( $object_id, $table, $data );
