Help! Serialized data.

Hi,
When saving post data, there are cases where MF sends arrays even if only one value is allowed (like a dropdown menu with only one option allowed).
The result is the data is saved as a serialized array containing one item (WordPress serializes passed arrays).
This makes custom queries uselessly complicated and breaks functionnalities for plugins which doesn’t handle serialized data.

I successfully modified mf_post.php to save the value of a specific field as string, but it would be more efficient to filter out fields by type.
However I’m only able to use the $field_name variable, I can’t get the $field_type variable.

I wonder what happened with the function mf_process_value_by_type($field_name,$value) in mf_post.php -> mf_save_post_data( $post_id ).
It seems it never got implemented.

If a developer could chime in, please.
Any help would be greatly appreciated.

Well that was rather simple actually.
The modifications bellow allows for writing and reading string data in place of serialized array if the array contains only one child (dropdown)

mf_post.php, line 278:

// Adding field value meta data
add_post_meta($post_id, "{$field_name}", $value);

becomes:

// Adding field value meta data
if(is_array($value) && count($value) == 1){
  add_post_meta($post_id, "{$field_name}", implode('',$value));
}else{
  add_post_meta($post_id, "{$field_name}", $value);
}

mf_front_end.php, line 481:

case 'dropdown':
  $result = ($options['multiple'])? $value[0] : $value ;
  break;

becomes:

case 'dropdown':
$result = ($options['multiple'] == '0' && is_array($value))? $value[0] : $value ;
break;

This doesn’t break previously entered data and update new/modified to the new format.
