Php and links

[kan29]

Hi,

 

I am very new to php, and working on a personal project to learn it at the moment, i am having trouble with links and php. Here is what i want to do, I have an image map, which is set up and working, now i got a mysql database too, what i want to do is when you click on a particular area, i want it to generate the results from the database using a query, where the name of the clicked area will be used in the query, question is how do i pass the value of the name to php. i know how to do that in a form, but can you do this for <a> tags or anything else. any help will be appriciated.

 

thank you.

<a href="whatever.php?name=wombat">wombats</a>

 

and then in whatever.php

 

<?php
$name = $_GET['name']; // sets $name = wombat in the example
?>

An area of your image map should link to something like query.php?name=downtown, and then your script would look like this:

 

query.php

<?php
// check if the name exists/is allowed (important when used in a MySQL query. Else use mysql_real_escape_string)
if (in_array($_GET['name'], array('downtown', 'center'))) {
// use the name stored in $_GET['name'] for your query
} else {
echo 'This area does not exist!';
}
?>
