Save image metadata (id, url ..) in a custom meta data field after post creation

  1. Hello,

    I'd like to save image metadata (id, url, title, description) into a custom metadata fields after a form has been submitted and a post has been created.

    I figured out that I have to use gform_after_submission hook, so I can see the value per image with all the required data that looks like|:|FF S4 Image 1|:||:|FF S4 Image 1 Descr|:|117

    Is there a GF function I should use to extract that data (in case there is one, so it will be compatible with any future changes).

    OR do I have to do it myself something like:
    list($url, $title, $caption, $description) = explode("|:|", $value);

    Just wanted to make sure to use native way, to make sure it's more robust for future changes if any.

    Many thanks, Dasha

  2. From the code in entry_list.php:

    [php]case "post_image" :
        list($url, $title, $caption, $description) = rgexplode("|:|", $value, 4);

    You have it exactly right. I would use rgexplode as shown there, with the 3rd parameter, but otherwise I don't see any other native functions to handle this.

  3. Hello Chris,

    Thanks very much for letting me know to use rgexplode. Works well for extracting img meta data to store it in custom meta fields.
