If you have a persistent object cache setup, then transients will not write to the database: they’ll be stored in memory. Reviewing the definition of set_transient() this can be seen: if ( wp_using_ext_object_cache() || wp_installing() ) { $result = wp_cache_set( $transient, $value, ‘transient’, $expiration ); } Only if no external cache is in place do … Read more
No: each transient will need a unique name. Per the documentation: If a transient exists, this function will update the transient’s expiration time.
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
Without object caching plugins transients are stored using options API and, if set to expire, they have auto-load disabled. Meaning: First request to transient needs to fetch it from database. Subsequent requests will get data from memory. However note that “memory” here is memory space of single specific page load. It’s not shared and not … Read more
Should be the transient(cache files) of the plugin wp-less that convert the css code in less through a compiler. After downloading wp-less check the compiler.class to see how the plugin cache the code. I don’t think this is hacking.
It looks you’re using different transient names in get_ and set_. Try the following: $transient_key = ‘apidata_json_cache’; $expiration = 2*60; // 2 Minutes if( false === ( $feed = get_transient( $transient_key ) ) ) { echo ‘<!–Fresh data–>’; /*data extraction process here, which is than stored in $feed*/ set_transient( $transient_key, $feed, $expiration ); }
I have managed to do the following. I made a clear cache button: function advanza_direct_plugin_delete_transients() { delete_transient( ‘advanza_direct_terms_of_service’ ); delete_transient( ‘advanza_direct_privacy_policy’ ); // at the end redirect to target page exit( wp_redirect( admin_url( ‘admin.php?page=advanza-direct-plugin-settings’ ) ) ); } add_action( ‘admin_post_advanza_direct_plugin_delete_transients’, ‘advanza_direct_plugin_delete_transients’ ); I put this where I have my admin logic: <form action=”<?php echo admin_url(‘admin-post.php’); … Read more
Transient is never set. Why?
Use sessions when they are appropriate. Our fellow mod @EAMann has written a useful session class for exactly these cases. There is a plugin described here that offers a different API. Just make sure to start the session only when you really need one. Google and other crawler don’t accept cookies, so you would end … Read more
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
