strange problem with sessions

stefke

we've a form on several pages

two variables

locatie (location in English)
cursus (course in English)

we've the following session script

<?PHP
session_cache_limiter('nocache');
session_cache_expire ('1');
session_start();

if (isset($POST['cursus'])) {
$cursus = $POST['cursus'];
session_register('cursus');
}
if (isset($POST['locatie'])) {
$locatie = $POST['locatie'];
session_register('locatie');
}

At the rest of that page we've a normal php script with a sql query that returns a list of the courses that match the keyword for the chosen location

Nothing fancy, isn't it?

Now, when we go to www.syntra-ab.be/trainingenopleiding.html and use the search box, we get the results we want.

If we go back to that page and use a new search string, we also get the results we want.

BUT, when we go from teno_result.php to teno_indekijker.html for instance and we use the search box on teno_indekijker.html for some reason we always get the search result that we've done during the first search on the main page

Do you understand what I mean?

I'm desperately looking for an answer to solve this problem and any help will be greatly appreciated.

I think that you have to move from a php to a php page when you use sessions, if i am right

Consider these lines:
$cursus = $_POST['cursus'];
session_register('cursus');

The first sets $cursus to the POSTed form value.

The second registers $cursus as a sessioned variable. If there is already sessioned data called 'cursus', that sessioned data will overwrite the current value of $cursus.

So if $_POST['cursus']="foo" and cursus already has "bar" sessioned, then those two lines will first set $cursus="foo", and then immediately set $cursus="bar". Goodbye "foo".

Consider just saying
$SESSION['cursus']=$POST['cursus']; instead. It does what you mean, and avoids ambiguity about what variable is getting set to what value when. It's also a tick faster.
