The simplest thing to do is simply delete the transient when the username is updated. Then the next time get_json() is run it will see that the transient is not set, just as if it had expired, and retrieve the data and save the transient again. So inside the update() method of your widget class … Read more
I think I’d build that upon and already existing plugin that does the counting for me. I have made quite good experience with Post Views Counter as it also lets you use it in WP_Query. But WP-PostViews looks promising as well. Choose one. Next I’d query posts by view count from a WordPress cron event … Read more
I mean in shortly your code is wrong in the first line, the comparing is wrong. The variable $post should store = the data of the request via get_transient() and not compare ===. So you should switch to: if ( false === ( $posts = get_transient(‘posts_array’) ) ) { // this code runs when there … Read more
How does one go about locking down transient API requests for multiple threading? Has anything done some benchmarking, just how much can the transient API handle for multiple concurrent requests? Under normal circumstances Transients API is essentially thin wrapper on top of Options API. The difference is that (unlike plain options) transients might make use … Read more
The first problem is that your parentheses are incorrect in your IF statement. if ( ( $get_post_categories = get_transient( ‘this_blog_categories’ ) === FALSE ) ) Should be: if ( ( $get_post_categories = get_transient( ‘this_blog_categories’ ) ) === false ) You’re wanting to assign the value, and then test that value against false. Because of your … Read more
Try something like this, which would save in transient for 12 hours. Let me know if anything does not make sense. <?php $value = get_transient( ‘value’ ); if ( false === $value ) { $output = “”; $html = file_get_contents(‘http://www.example.com’); $doc = new DOMDocument(); libxml_use_internal_errors(TRUE); // disable libxml errors if(!empty($html)) { $doc->loadHTML($html); libxml_clear_errors(); $xpath = … Read more
Although both of your options (that is, using transients or using a cron job) are viable, I’m a fan of using transients unless the dataset is exceptionally large or if there is some need to automate the process. Without seeing much of your current code, it’s difficult to give a working example. Nonetheless, if you … Read more
Yes, WordPress uses cookie to keep track of who is logged in in cookies. But you don’t have to rely on it. If you want to check if user is logged in, you can just use is_user_logged_in function and you can identify a user by his/her ID which you can get by calling get_current_user_id function.
Take a look at the relevant bits of the database description for that table. Field Type option_name varchar(64) option_value longtext The key is 64 characters max. The value is longtext which should be more than you need. To have you caching work, you need a unique value for the key, but it doesn’t have to … Read more
Some caching plugins that cache entire pages or sites in .html files so obviously anything generated on a page will be “cached” in that file. Other kinds of caching stores information in memory (RAM). The answer differs some according to which kind of caching you are talking about, but… If I use transient api is … Read more
