extract 2 parameters from a ulr string

[LuckyBoy]

I need extract 2 parameters from a ulr string http://www.mydomainname.com/?aid=CD1&0=<memberid> and append them to a couple of hidden fields on my form.

I am ok with PHP form scrips and the basic stuff but have now idea how to do this and have been searching the forums for a couple of days now without success, can anyone assist me with this any help welcome.

Thanks

<form action="" method="POST">

<?php
foreach ($_GET as $key => $value)
{
	echo '<input type="hidden" name="' . $key . '" value="' . $value . '">';
}
?>

<input type="submit" name="submit" value="submit">
</form>

You'd probably be better off going straight for the indexes rather than using a foreach (to avoid the potential for malicious injection of code).

If you know the indexes, the grab them like so:
$index1 = $GET['index1'];
$index2 = $GET['index2']; (or whatever they are named)

Then use those values to fill in your hidden fields instead.

Either way, you should read up on the usage of predefined variables in the manual (including the use of other type of global and superglobal arrays such as $POST, $SERVER, etc.)

Firstly Devinemke, TheDefender thanks for your help with this I really appreciate it.

I have one point that am still not sure of, how, where does the ulr get a mention it is only for these to hidden fields. The page ulr is just http://www.mydomainname.com and does not contain these “aid” and “&0” parameters.

So I suppose my question is in the below there is no reference to http://www.mydomainname.com or the “aid” and “&0” parameters.

<form action="" method="POST">

<?php
foreach ($_GET as $key => $value)
{
echo '<input type="hidden" name="' . $key . '" value="' . $value . '">';
}
?>

<input type="submit" name="submit" value="submit">
</form>

the code i posted simply takes whatever variables that on the URL query string and sticks them into hidden form fields. TheDefender's point is that rather than take them all, you should only takes the specific variables you are interested in. either way you should properly validate the variables before using them in your script.

If it is in the URL then you use $GET and if it is a form then you use $POST. You fgirst posted a URL with the params in so they used GET, now you show a form so I say $_POST['varname'].

And given the way your form is generated then devinemke's foreach is the answer.
