storing javascript in text area

I looked at the documentation but I'm still having disabling sanitize for textarea field using the following code, can you point out what I'm doing wrong?

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = [
        'title' => 'Team Field Group',
        'fields' => [
            [
                'type'              => 'textarea',
                'id'                => 'embed_code',
                'name'              => 'Widget Embed Code',
                'sanitize_callback' => 'none',
            ]
        ],
    ];
    return $meta_boxes;
} ); 

another example that doesn't work:

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = [
        'title' => 'Story Field Group',
        'fields' => [
            [
                'type'              => 'textarea',
                'id'                => 'textarea_6dgymvsrfq5',
                'name'              => 'Full code snippet',
                'sanitize_callback' => 'none',
            ]
        ],
    ];
    return $meta_boxes;
} );

Wow! That was so simple!!

In reviewing the documentation regarding sanitization it was not clear that you can override the sanitization on any custom field you create by simply adding a "sanitize_callback" Attribute with the value= "none" in the Advanced tab on that field.

No coding necessary, nothing to add to the functions.php file, etc.

Could you somehow make this solution more visible in the documentation?

Thank you very much for staying with me on this and showing me how to solve my problem.

Hope you and everyone close are healthy and continue to stay healthy.

That’s a little more clear, but what’s missing is the screenshot showing how you can apply the sanitize_callback none so easily in a custom field advanced tab UI.

You say this:

Bypass The Sanitization

If you don’t want to sanitize the input value for a specific field (we don’t encourage this, obviously), then simply set the sanitize_callback to none:

And then you show the resulting code, but you never show where or how you set the sanitize_callback to none!

For me at least, I had no idea you could do that, and nowhere in the docs that I could find was a suggestion to use the advance tab attributes to do this. Maybe this is obvious to you, but I participate in a weekly WordPress support group that has PHP and JavaScript engineers, WordPress experts, and nobody could figure out how to do it. One of the reasons I use metabox and beaver builder and beaver Thiemer is to avoid hand coding. The actual solution is so simple and elegant, but it is not intuitive.

Thanks again for making such a great product.

That’s perfect +1

I made a blog post about it on my website too
