Fix for Validation Error when using multiple forms

I previously posted here about generic errors which prevented form submission when using multiple form/lists throughout a site.

I’ve created a patch. These edits are all to the mailigen-widget.php file:

around line 104 remove this line:

$errors = $this->validate($fields);

and add this line below the $listId declaration at about line 114:

$errors = $this->validate($fields, $listId);

Next around line 157 change the validate function declaration to:

function validate($fields = array(), $selected_list = '') {

Finally change this around line 160:

$allFieldsParams = $this->getOption('mg_fields');

to this:

if( isset( $selected_list ) ) {
  $allFieldsParams = $this->getOption('mg_fields_'.$selected_list);
}else{
  $allFieldsParams = $this->getOption('mg_fields');
}

This will effectively validate the fields that relate to the specific OptIn vs the generic list OptIn.

Hope this helps.
