根据URL中的变量添加到页面标题标记

Question

I have seen the following thread but it's a bit beyond me...

How can I change the <title> tag dynamically in php based on the URL values

Basically, I have a page index.php (no php in it just named to future proof - maybe now!). It contains numerous lightbox style galleries which can be triggered from an external link by a variable in the URL - e.g. index.php?open=true2, index.php?open=true3, etc.

I would like the index.php title tag - to include existing static data + append additional words based on the URL variable - e.g. if URL open=true2 add "car gallery", if URL open=true3 add "cat gallery", if URL has no variable append nothing to title.

Can anyone assist? I have been searching but either missed the point of posts or it hasn't been covered (to my amateaur level).

Many thanks. Paul.

Answer 1

At the top of your php script put this:

<?php

# define your titles
$titles = array('true2' => 'Car Gallery', 'true3' => 'Cat Gallery');

# if the 'open' var is set then get the appropriate title from the $titles array
# otherwise set to empty string.
$title = (isset($_GET['open']) ? ' - '.$titles[$_GET['open']] : '');

?>

And then use this to include your custom title:

<title>Pauls Great Site<?php echo htmlentities($title); ?></title>
