Double Serialization

    I understand you removed the double serialization of the meta information in version 3.1.10, with both a base64 and a WordPress serialization.

    I’m working on an old site that was left unmaintained for a number of years. URIS was crashing it, and the double serialization was the reason. The meta data is still stored in the database with the double serialization intact. I was able to restore the page functionality by modifying the plugin code to perform the double de-serialization.

    My question for you is: is there any simple way to convert the old, double-serialized format to the current, non-serialized format? For example, would simply re-saving the form have that effect, or would it erase all the existing metadata because it didn’t understand it?

    I could also modify the information directly in the database, if you can give me an idea of what parameter names I should look for.

    I changed the metadata database entries for “ris_all_photos_details” to use the WordPress serialized information instead of the double-serialized information that had been there. This now prevents the slider from crashing the page.

    However, the sliders image placeholders are gray and don’t show the images themselves. Is there something else I need to modify?

    I suggest putting in some error-handling code to see if the result of each get_post_meta() call in layout.php is a string or an array. That way you could exit gracefully instead of crashing the page with a message that WordPress is broken. Here’s something like what I’m thinking:

    
$URIS_All_Slide_Ids = get_post_meta( get_the_ID(), 'ris_all_photos_details', true);
if (!is_array($URIS_All_Slide_Ids))
  $URIS_All_Slide_Ids = [];
$TotalSlideIds = count($URIS_All_Slide_Ids);

    I’m making the assumption that the rest of the script would work with no metadata and a count of zero, but this is just an example off the top of my head. You get the idea. It’s the count() call that crashes the script, because it’s expecting an array and is getting a string.

    Okay, I found the “Recover Old Sliders” menu option. It didn’t work and erased all the slides, but I found it. So I guess that answers all my questions. Marking as resolved.
