PHP Querystring Functions
05 December 2006 | 53 comments | links, code, development, url, querystring, reference, php, functions, programming, tips, variable
Adding and removing variables to and from URLs using PHP can be a relatively simple process admittedly, but I have a couple of functions I use often to make the process even less time-consuming.
Add Querystring Variable
A PHP function that will add the querystring variable $key with a value $value to $url. If $key is already specified within $url, it will replace it.
function add_querystring_var($url, $key, $value) {
$url = preg_replace('/(.*)(?|&)' . $key . '=[^&]+?(&)(.*)/i', '$1$2$4', $url . '&');
$url = substr($url, 0, -1);
if (strpos($url, '?') === false) {
return ($url . '?' . $key . '=' . $value);
} else {
return ($url . '&' . $key . '=' . $value);
}
}
Remove Querystring Variable
A PHP function that will remove the variable $key and its value from the given $url.
function remove_querystring_var($url, $key) {
$url = preg_replace('/(.*)(?|&)' . $key . '=[^&]+?(&)(.*)/i', '$1$2$4', $url . '&');
$url = substr($url, 0, -1);
return ($url);
}
Numbered Google Results User Script

A user script for Opera and Firefox that automatically numbers Google search results. Updated 16 Nov 2006 following changes to Google results page code.
The Search Jump user script provides a quick way to compare searches on various engines (or just to jump to another engine when the one you are using has poor results). It provides a small box at the bottom right of a search window, with links to the same search at other major search engines.

"Select All" JavaScript for Forms Posting to an Array
28 July 2005 | 55 comments | select, html, php, array, forms, javascript, checkboxes, form, all
The problem that led to this snippet of code was that when posting from a form to a PHP script, you may sometimes want to have several fields with the same name and different values. For example, you might want people to be able to tick boxes to indicate which cities they have been to from a list. You would normally add "[]" to the name of the field inputs, like so:
<input type="checkbox" name="cities[]" value="London"> London
<input type="checkbox" name="cities[]" value="Paris"> Paris
<input type="checkbox" name="cities[]" value="Berlin"> Berlin
<input type="checkbox" name="cities[]" value="Madrid"> Madrid
<input type="checkbox" name="cities[]" value="Rome"> Rome
When the form is received by PHP, whichever items are ticked in the cities list above are accessible in the array $_POST['cities']. This is very handy.
Unfortunately, the addition of square brackets causes trouble with JavaScript, especially with a "Select All" function - which allows you to check all boxes at once by clicking a single one. This script works around that using regular expressions.
