How to make a field required in WC Vendors Pro

functions.php

To require, or not to require, that is the question......  In the future, we'll make these into checkboxes to require/not require,
but for now you use filters.  Add this code to your themes functions.php file.  Here's the process:

1.) Find the filter for the field you want to adjust the requirements.  This file is in /plugins/wc-vendors-pro/public/forms/class-wcvendors-pro-product-form.php

2.) Create a filter for each field you'd like to make required (or not required).  The code below will make the description required:

/* WC Vendors Pro - Make Description Required */
function wcv_product_description_required( $args ) { 
    $args[ 'custom_attributes' ] = array( 
	'data-rules' => 'required', // Change 'required' to '' to make it not required (just remove the word required but keep the single quotes)
	'data-error' => __( 'This field is required.', 'wcvendors-pro' )
	); 
    return $args; 
} 
add_filter( 'wcv_product_description', 'wcv_product_description_required' ); 

3.) That's it!  Have fun.

Some fields are REQUIRED already, such as title and description.  To change this:

/* WC Vendors Pro - Make Description NOT Required */
function wcv_product_description_required( $args ) { 
    $args[ 'custom_attributes' ] = array(); 
    return $args; 
} 
add_filter( 'wcv_product_description', 'wcv_product_description_required' );
