Meta Box

Hi,

It's an interesting and rare case. Checking the internet connection while clicking the Publish/Update button maybe avoid this issue.

I'm going to create a feature request for the developer team to cover this case. Thank you.

Hi,

Because only the field group has the key fields in the settings array. So it will display the warning notice like Invalid argument supplied for foreach(). To solve this issue, you should check if the key exists in the array before using the loop.

foreach ( $group1_settings['fields'] as $group1_field_settings ) {
    if( array_key_exists( 'fields', $group1_field_settings ) ) {
        foreach ( $group1_field_settings['fields'] as $field_settings ) {
            ...
        }
    }
}

Hi,

Yes, the field post just supports selecting post (post types) and save the post ID as the post meta so it does not have the feature reciprocal like the Relationships extension.

Hi,

The extension MB Group can be installed via Composer. You can get the sample file composer.json here https://github.com/wpmetabox/library/blob/master/composer/composer.json.

Check if the plugin MB Group is loaded before requiring the file vendor.php

if( ! class_exists( 'RWMB_Group' ) ) {
    require 'meta-box/vendor/autoload.php';
    // code goes here
}

Hi Jens,

I've received your staging site information via Freshdesk, there are too many issues in your case to not display the field value with the Oxygen Builder while it should be.

• The custom fields are assigned to the post type Square, not the Page. See https://share.getcloudapp.com/p9urnLy5. Using the helper function rwmb_meta() without the third parameter $post_id means the code will take the current post ID. The Page does not have the custom field => the helper function cannot get the field value.
• I do not see the code which creates the custom table in the file functions.php of the theme or a snippet of Code Snippets => the helper function cannot get the field value from the custom table.
• If you create the custom table with other code as well but the code does not create the parameter to pass the value table name.

function acf_picture($mb_field) {
    $output_array = rwmb_meta($mb_field, ['storage_type' => 'custom_table', 'table' => $wp_square] );
    echo $output_array['full_url'];
    return;
}

Oxygen does not know what the variable $wp_square is when you pass only the field id to the function <?php acf_picture('sq_image_standard'); ?>

The snippet should be (fixed table name):

function acf_picture($mb_field) {
    $output_array = rwmb_meta($mb_field, ['storage_type' => 'custom_table', 'table' => 'wp_square_content'] );
    echo $output_array['full_url'];
    return;
}

Or dynamic table name:

function acf_picture($mb_field, $wp_square) {
    $output_array = rwmb_meta($mb_field, ['storage_type' => 'custom_table', 'table' => $wp_square] );
    echo $output_array['full_url'];
    return;
}

then pass the argument when calling the function <?php acf_picture('sq_image_standard', 'wp_square_content'); ?>

I've removed the setting custom table in the builder to save the field value in the default table of WordPress then the code works as well. You can check the page https://staging.wiconsult.eu/index.php/t02_single-image_php-block/.

Remember the note when creating the custom table https://docs.metabox.io/extensions/mb-custom-table/#notes.

Hi Cinza,

It looks like the select field, not select_advanced (default). Please deactivate all plugins except Meta Box, MB extensions and switch to the default theme of WordPress Twenty Twenty to check the issue again. If it does not solve, I recommend checking your code, it might use the field type select.

You can also get connections with posts that have other statuses (draft, pending, private...) by using the setting query_args.

The code would be:

'from' => 'CPT',
'to' => array(
    'post_type'    => 'CPT',
    'field' => array(
        'field_type' => 'select' //Check the field type here
    ),
    'query_args' => array(
        'post_status' => array( 'pending', 'draft', 'private' )
    ),
),

See more in the documentation:

Hi,

The plugin MB Relationships has not supported to link to the post selected on the backend yet. I'm going to create a feature request for the developer team to support this case.

Thank you.
