link generator script Options

[mrlk]

Not sure if this is the rightforum but...)

does anyone know of a link generator script for this:

i'm using google maps on joomla and am creating a number of maps - what i would like to do on one main page is have a set of checkboxs/radio buttons so that the user can pick say "towns" & beaches and it would generate the corresponding link on a form button

the variables are all numerical

eg towns is 1
beaches is 2
bars is 3 etc

the result would be
/index.php?option=com_google_maps&category=1,2

if the user wanted say towns (1) and bars (3)

then the result would be
/index.php?option=com_google_maps&category=1,3

basically i need to i think get the variable and add it to the predetermined url and check whether there is anoter var picked, if so add a comma before it, if not then just the variable itself

im sure this is far easier than i think but i cant get my head around it

That's fairly easy to do in PHP. Basically, you give all your checkbox the same name with brackets at the end, so for instance

HTML

<form action="submit.php" method="post">
<div>
<input type="checkbox name="category[]" id="bar"><label for="bar">bar</label><br>
<input type="checkbox name="category[]" id="beach"><label for="breach">beachl</label><br>
<input type="checkbox name="category[]" id="hotel"><label for="hotel">hotel</label><br>
<input type="submit">
</div>
</form>

CODE

<?php 
$categories = "";
if(!empty($_POST)) 
 for($i; sizeof($_POST["category"]); $i++)
  if($_POST["category"][$i] == true)
   $categories .= "$i,";
if(!empty($categories))
 header("Location: /index.php?option=com_google_maps&category=$categories");
else do something different if there are no categories.
?>

Something like that. Not sure how familiar you are with PHP so maybe that doesn't actually help at all though.
