10 Very Useful WordPress Hacks

WordPress is a great platform but it’s not perfect, so that’s why many users want to optimize it a little. A friend of mine sent me a document with a bunch of wordpress scripts,  so I wanted to share some of them with you. Please note that I’m not the one who wrote them; these scripts are so popular that I couldn’t find the authors for them. So, let’s thanks the unknown coders who make our life easier with their work. :)

How to open links in new window by default

First, open quicktags.js in the wp-admin folder.


if (!edCheckOpenTags(i)) {
var URL = prompt('Enter the URL' ,defaultValue);
if (URL) {
edButtons[i].tagStart = '<a href="' + URL + '">';
edInsertTag(myField, i);

Replace with:

if (!edCheckOpenTags(i)) {
var URL = prompt('Enter the URL' ,defaultValue);
if (URL) {
edButtons[i].tagStart = '<a href="' + URL + '"';
if (URL!='http://')
var defaultTarget = prompt('Enter the Target' ,'_blank');
if (defaultTarget) edButtons[i].tagStart += ' target="' + defaultTarget + '"';
} edButtons[i].tagStart +='>';
edInsertTag(myField, i);

Create and add the script above in “db-error.php” directly inside your /wp-content/ folder and WordPress will automatically use that when there is a database connection problem.

<?php // custom WordPress database error page
  header('HTTP/1.1 503 Service Temporarily Unavailable');
  header('Status: 503 Service Temporarily Unavailable');
  header('Retry-After: 600'); // 1 hour = 3600 seconds
  // If you wish to email yourself upon an error
  // mail("", "Database Error", "There is a problem with the database!", "From: Db Error Watching");
<title>Database Error</title>
body { padding: 20px; background: red; color: white; font-size: 60px; }
