get

i added some image to my wordpress library. now i need to retrieve one of them by name and get it's URL. note that i didn't attach them in any post. thanks for your attention. A straightforward approach - using a direct SQL SELECT statement with the WordPress database abstraction API: $wpdb->get_var( $wpdb->prepare(" SELECT ID FROM $wpdb->posts WHERE post_title = %s AND post_type = '%s' ", $title, $type) ); You can incorporate this into a function (you can place in your functions.php file): function get_post_by_title($title, $type = 'post') { global $wpdb; $post_id = $wpdb->get_var( $wpdb-

It's a well covered topic, but I'd like to get some confirmation on methods of using data from user variables, in a few different situations. The variable is never used in a database, never stored, only displayed on screen for the user. Which function to use to make sure no html or javascript can screw things up? The variable is taken into the database, and used in SQL queries. The variable does both. At the moment I xss_clean, and strip_tags. I've always done this, just by autopilot. Is there a better technique? Apologies if there's an identical question out there. I kinda assume there is,

I have a piece of code that's supposed to do a http get request. The program exited successfully without error, but I didn't see any response and it didn't even go inside the callback function! At first I thought it's because http is asynchronous and put a large loop in the end but that didn't work either. Does anyone know this issue? Only the first console log sendHttpRequest and 444 gets printed. I also tried the http.get but it didn't work either. function sendHttpRequest (url, callBack) { console.log("sendHttpRequest"); //constrct options var options = { host: 'www.google.com', path: '

My problem can be easily created by the scenario below: //create a gregorian calendar object that set the date and time as 4th June 2012 at 10:30PM Calendar calendar = new GregorianCalendar(2012, 6, 4, 22, 30); //when I print out these: System.out.println(calendar.get(Calendar.DAY_OF_WEEK)); System.out.println(calendar.get(Calendar.MINUTE)); System.out.println(calendar.get(Calendar.HOUR)); System.out.println(calendar.get(Calendar.DATE)); System.out.println(calendar.get(Calendar.MONTH)); System.out.println(calendar.get(Calendar.YEAR)); //output reads as: 4 30 10 4 6 2012 //so does calendar.get
