see the "name" of an input field

[aebstract]

Don't know how to topic this, but I have an input like this:

<input type=\"text\" name=\"$id$material\" value=\"{$array3['qty']}\" size=\"3\" maxlength=\"3\" />

 

Maybe I should say, several inputs. They each have a unique name as you can see. No two will be the same with this method. Now while I'm running another script after this has been submitted, I'm needing to do something if the name of this input field matches the id/material that I am currently at in my loop. So I need to compare the name before I grab the value. I have no problem grabbing the value of my inputs with a $_POST[$id$material] type of thing.

Use double $$ before the variable to get the actual variable name.

Would it be:

$postqty = $id2.$material2;

echo "$$_POST[$postqty]";

or

$postqty = $id2.$material2;

echo "$_POST[$$postqty]";

 

The first one doesn't echo anything and the second one produces a white page.

 

 

 

edit: the actual post should be  $_POST['4mild'] or $_POST['8stainless'] something like that, which I'm needing to do a certain task whenever I get to the spot in my loop where idmaterial is = the piece inside that post bracket. Hope this makes sense.

Here we go,

 

$a = array('help4'=>'657', 'blue1' => '999');
$first = 'help';
$last = '4';
echo $a[$first.$last];
//echos 657
