Reply To: Applying Character Limits to Custom Fields in the Product Form

Hello,

You’re very close. When wanting to add validation rules you need to specify them as custom attributes in your field like this:

WCVendors_Pro_Form_Helper::input( array(  
				 'type'      => 'text',
				 'post_id'   => $object_id, 
				 'id'     => 'wcv_custom_product_includes_0', 
				 'placeholder'   => __( 'Included', 'wcvendors-pro' ), 
				 'desc_tip'    => 'true',
				 'custom_attributes' => array( 
		 			'data-rules' => 'max_length[120]', 

		 		)
			)
) );

cheers,

Jamie
