[Resolved] passing variables without form

kf6kmx

This probably has been covered someplace in the docs/forums, but I didnt find it.. wasnt sure what the search term would be.. didnt see it under "variables", or "parseing variables".

Heres what I'm trying to do:

I'm working on a site that will be a listing for classic cars.. there WILL be page feeding the listing generator from a form, and it is working (using the $_POST[]).
BUT, what I want to do is setup a way to pass the stock number direct to the page, so a link can be placed in another site (ebay auction, for example) and bring it up..
example:
http://mysite.com/showcar.php?CON-0044

where CON-0044 would be the stock number, and would be different on each call. This is pretty common in other CGI programming, but havent figured out how to parse the calling URL in PHP..

Thanks for the help!

URL variables are added to the $_GET global. Note if you use a POSTed form you cannot use the GET method at the same time.

I'm not opposed to changing to $_GET method. I just need to be able to call specific items directly. 🙂

Presumably you will use the passed GET variable to extract some data from a database and then lay up a form, so you would do something like

$sql = "select * from table where id = ".$_GET['CON'];

Only part I'm a little unsure of is how to parse the data from the calling header. Is there a system/environment cariable that gets set showing the URL that called the page?
The address on this reply is actually doing exactly what I'm after, has:
newreply.php?s=&action=newreply&postid=10452343

I need to parse the part after the first "?"

Thanks

Yep all query string data is put into the $_GET global. HTML forms submitted with a get method are actually just appended onto the query string.

newreply.php?s=&action=newreply&postid=10452343

$_GET['s'] == '';
$_GET['action'] == 'newreply';
$_GET['postid'] == 10452343;

Just shoot me now... :rolleyes:

That was too easy, thats why I wasnt seeing it. I was looking for some long drawn out process (can we say "Micro$oft Visual* programming background??")
