Set Variable on href click?

[redgunner]

How can I set a variable when <a href="#">Link</a> is clicked?

 

for example to set $variableX as integer of 1?

You'd define it within the query string

<a href="file.php?somevar=1">Link</a>

You'll use the GET super global for getting the variables from the query string, for this example you'd use the variable $_GET['somevar'] within file.php

 

<?php

echo 'Variable is set to: ' . $_GET['somevar'];

echo '<p>Lets see what is in the $_GET superglobal: <pre>' . print_r($_GET, true) . '</pre>';

?>

How could I achieve this with using javascript?

In what way? You can redirect with JavaScript using window.location, eg

window.location = 'file.php?somevar=1';

 

If you don't want the page to reload, then you'll need to use AJAX.
