Meta Box

Maybe you're right. I need to check that again. Can you tell me which field type are you using?

Hi,

Thanks for asking this. There are 2 internal helper functions rwmb_get_value() and rwmb_the_value() which are used in rwmb_meta() function. They're not 100% stable since v4.8.0 so I haven't put them in the docs yet.

Briefly, rwmb_get_value returns the raw value stored in the post meta, while rwmb_the_value returns (or outputs) the *meaningful* value in the frontend. Meaningful = option label for select box, post title for post field, a colorful dot for color field, etc.

Both functions accept the same parameters as rwmb_meta. Parameters also share the same meaning.

rwmb_get_value( $field_id, $args = array(), $post_id = null )
rwmb_the_value( $field_id, $args = array(), $post_id = null, $echo = true )

They also use $post_id if you want to get meta value from a specific post.

In your case if the result goes unexpected, please try setting up the $post_id. Anyway, there was also a topic reporting the same problem happened because of wrong post ID. But I couldn't find out why

Hi,

I think you're doing correctly. However, I will think more about a better way to suppress the error. For now, all fields' classes are loaded by autoload and it makes us impossible to use class_exists.

Unfortunately, it's not supported. The plugin is made for working with custom fields and should handle custom columns for custom field only. For the default WP columns, I made it support replacing them only.

However, you can do that with a simple code like this:

add_filter('manage_edit-POST_TYPE_columns', 'prefix_custom_columns');
function prefix_custom_columns( $columns ) {
    $columns['title'] = __( 'Lecture Name', 'textdomain' );
    return $columns;
}

For more details, you can check this tutorial.

Dear Yumiko,

It's me again, I've tried to login your website but got 404 error message.

Actually, I've exported your last meta box and imported successfully in your website before. I'll try one more time when your website is up again.

Best regards,

I highly recommend to include the main plugin and extensions using the TGM Activation Class. The TGM Activation Class is being proposed to be included in WordPress core. So, we have good reasons to use it.

But, if you want to include the tab extension in your theme anyway, then you have to do 2 things:
- Include the plugin main file
- Enqueue correct CSS/JS files

Your code above only did the 1st thing. To enqueue CSS/JS file, you can do this:

add_action( 'rwmb_enqueue_scripts', 'prefix_meta_box_tabs_enqueue' );
function prefix_meta_box_tabs_enqueue()
{
    wp_enqueue_style( 'tabs-ext', get_template_directory_uri() . '/inc/meta-box-tabs/tabs.css' );
    wp_enqueue_script( 'tabs-ext', get_template_directory_uri() . '/inc/meta-box-tabs/tabs.js', array( 'jquery' ), '', true );
}

Please double check the URL to files tabs.css and tabs.js.

Actually, I have tried with your production website and it works. I cannot replicate your bug on my PC because different environment. Can you please send me a screenshot or better video about how can you meet the bug?
