Meta Box Math CAPTCHA
A standalone WordPress plugin that adds a privacy-compliant Math CAPTCHA field type to the Meta Box ecosystem. This plugin provides a secure, AJAX-validated Math CAPTCHA that works seamlessly with both backend and frontend forms, including those created with the Meta Box Frontend Submission addon.

1. Install the plugin: https://github.com/baden03/mb-math-captcha
2. Add a math_captcha:

$meta_boxes[] = [
    'title'  => 'Contact Form',
    'id'     => 'contact_form',
    'fields' => [
        // ... your other form fields ...
        [
            'id'         => 'math_challenge',
            'name'       => 'Are you human?',
            'type'       => 'math_captcha',
            'save_field' => false, // Important: prevents saving the value
            'required'   => true,
        ],
    ],
    // Add the validation rule for the captcha
    'validation' => [
        'rules' => [
            'math_challenge' => [
                'math_captcha' => true,
            ],
        ],
    ],
];

wow..

The Text Domain needs to be added to the plugin header.

Maybe this helps?

yeah. no.

Hello Peter.
the real case is an advanced plugin that handles handles the uploading, storing and managing access for sensitive data. If you share your github handle, I would be happy to give you access to the repo that explains everything in detail, including a demo-plugin we created as a proof of concept.

We ended up creating a custom field type called secure_file_advanced that allows the passing of custom parameters to the $_REQUEST before the file is uploaded. To do this we needed to get very intimate with how metabox.io has implemented the WordPress AJAX Media Uploader on the back and frontend (three uploaders deep). Our case may be an edge case, but it dose extend the flexibility of existing file_advanced field.

Regarding field type file: no for all the reasons that we went with file_advanced in the first place.
Also, adding the upload_dir attribute to the field meta, visible on the frontend, is not desired.
Also, with thousands of members we needed more than just a single upload-directory.

No plugin, as there are not multiple languages. Just set WordPress to use a language other than EN, for example, DE_Formal. And yes the .po and .mo files are in wp-content/languages/plugins folder.

src/Forms/info.php:

protected function submit_button() {
		$submit_button = '<div class="rwmb-field rwmb-button-wrapper rwmb-form-submit">
			<div class="rwmb-input">
				<button type="submit" class="rwmb-button" id="'.esc_attr( $this->config['id_submit'] ).'" name="rwmb_profile_submit_info" value="1">'.esc_html( $this->config['label_submit'] ).'</button>
			</div>
		</div>';
		$submit_button = apply_filters( 'rwmb_profile_submit_button', $submit_button, $this->config );
		echo $submit_button;
	}

usage:

add_filter( 'rwmb_profile_submit_button', 'fix_frontend_submit_button', 20 , 2 );
function fix_frontend_submit_button( $submit_button, $config ) {
		$is_complete = get_user_meta( $config['user_id'], 'is_complete', true );
		if($is_complete){
			$submit_button = '';
		}
		return $submit_button;
	}

src/Forms/Base.php: function render()

...
do_action( 'rwmb_profile_before_form', $this->config );

		$form = '<form class="rwmb-form mbup-form" method="post" enctype="multipart/form-data" id="' . esc_html( $this->config['form_id'] ) . '">';
		$form = apply_filters( 'rwmb_profile_form', $form, $this->config );
		echo $form;
...

usage:

add_filter( 'rwmb_profile_form', 'fix_frontend_profile_form', 20 , 2 );
function fix_frontend_profile_form( $form, $config ) {
		$is_complete = get_user_meta( $config['user_id'], 'is_complete', true );
		if($is_complete){
			$form = str_replace('method="post"', 'disabled', $form);
		}
		return $form;
	}

update, nevermind, found rwmb_profile_after_process

This has been happening across all sites that is running the latest 5.7.5 version of MetaBox.
If it helps, we can provide step-by-step instructions to recreate the issue, but figured it was self explanatory
