Why can’t I save encrypted data in a transient?

by

So the answer was to use base64_encode and base64_decode. So basically doing something like this to set the transient: $json_contact_info = json_encode( $contact_info ); $transient_data = encrypt_text( $json_contact_info ); $transient_array = base64_encode( $transient_data ); $transient_set = set_transient( $transient_name, $transient_array, 60 * 60 * 24 * 7 ); And then to get the transient: $decrypted_transient_data = … Read more

Ajax call to transients

Clear Transients

Unfortunately, expired entries will only be deleted if you attempt to access the transient again. If you don’t access the transient then, even though it’s expired, WordPress will not remove it. This is a known “issue” and is due to be corrected at some point in the WordPress core code. -Copied from: Artiss Transient Cleaner … Read more

Set transient with get posts error

by

If what you want is for this function to run once a day and loop through all matching posts (removing img tags), I think this should do the trick: <?php function remove_images_form_past_posts() { if ( get_transient(‘images_removed_from_past’) ) return; $args = array( ‘post_type’ => ‘post’, ‘year’ => 2013, ‘monthnum’ => 1, ‘day’ =>28, ‘post_status’ =>’publish’, ‘category’ … Read more
