If you’re using custom post types, i’d save those date entries as post_meta entries (http://codex.wordpress.org/Function_Reference/add_post_meta). So if your client clicks on a date, you start an ajax request to your plugin/theme file to add or remove a meta entry. you can create one meta_entry named _availability for example and save all dates there (you can … Read more
Don’t even start. Ignoring official API is a no go, at best it will just creat headache for you and nasty surprise for the users when the plugin will fail when pinterest changes something and since it forces you to….. store user and password in a very unsecure way. This might be ok if your … Read more
Transients should be used for short (for varying definition of it) time caching, and they are by design not reliable. From your description it sound like you are using them in a manner they were not designed to support and therefor probably the “best” for you is to not use transients at all.
Transients are not guaranteed to use database at all. They will use object cache if it is enabled. And since there is no bulk delete in object cache API, effectively there is no reliable way to clear out transients across all possible environments. There are some performance reasons to clear them out of database (which … Read more
Did you confirm it was the transient values causing the options to not update? Here’s the WordPress function to clear transient values: https://codex.wordpress.org/Function_Reference/delete_transient An example: <?php // Create a simple function to delete our transient function edit_term_delete_transient() { delete_transient( ‘the_transient_name_to_delete’ ); } // Add the function to the edit_term hook so it runs when categories/tags … Read more
Do you just want this lines ? $midnight_time = strtotime(‘tomorrow’) – time(); set_transient( ‘transient_name’, $transient_datas, $midnight_time); $midnight_time represent the seconds before midnight happens. You can ask your server to curl a page with a random parameter if you have cache to be sure your transient is consumed with a cronjob.
A. This is a good idea in general? I’m quite new to transients. No, not really. If your data is for display and search then it’s not really ‘transient’, is it? You should store the data properly in a more permanent place and periodically sync it. If the data from this API makes sense as … Read more
I assume the widget and the “Refresh now” button are shown on the front-end, yes? One option to delete a transient is to use ajax to do it. This is rather rough example, but I hope it gives you the idea what to do. You can read more about Ajax in WordPress from the codex. … Read more
For your use case, no. Using PHP sessions – will not work on most hosts, and will make that data available only to the browser and the current PHP request. This severely limits the usefulness Using Cookies – will work everywhere but have the same issue that you can’t persist server side or track things … Read more
I have set set_transient( ‘pgggo_acf_list_transient’, $pgggo_qry, 12 * 7000 ); is that too high? 12 * 7000 is just over 23 hours. Whether or not that’s too high (or low) depends entirely on your specific needs. The expiry time should be based on how often the data needs to be refreshed. What if there is … Read more
