Quick question... how do we assign the new image URL (from the media gallery) to the custom field. Currently, the upload works great, but the custom field is still pointing to the gravity forms upload directory and not the Media Gallery upload directory. See screenshot here: http://b3.ms/P5Z9ZD6gKnlb
Would like to update it to the URL of the uploaded photo after this function has placed it into the WP Media Gallery: http://idahoforests.local/wp-content/uploads/forest-photo-driggs5.jpg
Hello! A noob question. Where do i put this php file in order for this to work :)?. Or just copy this into theme's functions.php?
Many thanks for your help.
Hi, I'm getting this error
Catchable fatal error: Object of class WP_Error could not be converted to string in C:\wamp64\www\Intranet\wp-content\themes\woffice\functions.php on line 152
Line 152 is the $query assignment
$query = "SELECT ID FROM '{$wpdb->posts}' WHERE guid='$image_src'";
any idea on why I'm getting this error?
Thank you @saltnpixels!
I copied the code to my functions.php file and changed the "postCustomFieldName" to my custom field name "test_image_upload".
but it is not working. when I upload an image to the field, there is no image uploaded to the media library. Any one knows why?
Worked Beautifully! Thank you, thank you, thank you!
