How do I pass variables to associative arrays?

[danielrc15]

Hi,

I need help passing variables from the URL to associative arrays.

I currently have:

$params = array(
'keyword' => $t1,
'mode' => $t2
);

My 2 variables are in my URL namely:

test.php?t1=this&t2=that

BUT I get an error, can you tell me how to pass variables from the URL into an Array.

Thanks

Daniel

Read the FAQ of this forum on register_globals and using the superglobal arrays.

Hi read those notes, but I'm none the wiser, they do discuss getting values out of arrays, but not how to put variables into associative arrays.

Do I need to use the $$t1 sort of syntax?

Thanks

You would use:

$params = array(
	'keyword' => $_GET['t1'],
	'mode' => $_GET['t2']
);

$_GET[] is the superglobal array that you need to access.

Thanks for your help.

That sorted it!

Note you can also build a form like so:

<FORM>
<INPUT TYPE="TEXT" NAME="lname[]">
<INPUT TYPE="TEXT" NAME="fname[]">
..
..
<INPUT TYPE="TEXT" NAME="lname[]">
<INPUT TYPE="TEXT" NAME="fname[]">
..
..
</FORM>

and that will result in the vars being brought in with $_POST['lname'] being an array you can extract:

$lname = $_POST['lname']

so that you now have $lname[0] being the first one, $lname[1] being the second and so on.
