$_GET with unknown string

[pea]

Hello. How would you get a variable from a url using $_GET. umm.. for example:

http://www.sitepoint.com/forums/newt...newthread&f=34 ... 34 could be anything, so i couldn't just do $number = 34, i'd have to do something like $number = <name of submision>.

Sorry i explained that badly....

my code:

for each line of a file it had this form:

<form action='' method='post'><input name='' type='submit' value='X'>
<input name='' type='hidden' value='$line_num'></form> 

When i come to the delete line function, on this line:

unset($file[$_GET['???']]); 

..yeh. Thanks. Pete

You are using POST method in a form, and you also haven't set up name for input field.

<form action='' method='post'><input name='' type='submit' value='X'>
<input name='line' type='hidden' value='$line_num'></form> 

$line = $_POST["line"];
