paulund / wordpress-always-checked-remember-me.php
Created April 2, 2013 20:39
There is a login box on the Wordpress admin area login page to make sure this is always checked use the following snippet. Only use this if you know the only time admin users access the admin area is going to be on a private computer. Example of using it is http://www.paulund.co.uk/set-remember-me-to-be-always-checked
<?php
function login_checked_remember_me() {
add_filter( 'login_footer', 'rememberme_checked' );
}
add_action( 'init', 'login_checked_remember_me' );
function rememberme_checked() {
echo "document.getElementById('rememberme').checked = true;";
}

paulund / update-row-with-highest-id.sql
Created June 3, 2013 19:58
When you need to update a database row with the highest ID in the table. You can get the highest id by using the MAX() function but this function doesn't work in a nested select so you can't do this. UPDATE table SET name='test_name' WHERE id = (SELECT max(id) FROM table) Therefore you need to use a different way of getting the highest ID. This …
UPDATE table SET name='test_name' ORDER BY id DESC LIMIT 1;

Instead of sending debug data to a log file, just display it in the browser console with the following PHP snippet.
<?php
/**
* Send debug code to the Javascript console
*/
function debug_to_console($data) {
if(is_array($data) || is_object($data))
{
echo("<script>console.log('PHP: ".json_encode($data)."');</script>");
} else {
echo("<script>console.log('PHP: ".$data."');</script>");

paulund / cache-pages-with-php.php
Created June 25, 2013 18:27
Here is a quick code snippet which will allow you to easily cache pages in PHP.
<?php
//cache file
$cachefile = 'cached/'.date('M-d-Y').'.php';
//Total time the file will be cached in seconds set to 10 hours
$cachetime = 36000;
//If the cache file already exists and the cache file is over 10hours old then display the cache file
if (file_exists($cachefile) && time() - $cachetime < filemtime($cachefile)) {
include($cachefile);
