can you do $_POST['$My_Variable']??

[john_6767]

ok i'm trying to get the value of a posted field that has the name stored in my variable.. is this possible??

 

$_POST['$My_Variable']

 

i have some fields named quantity_1, quantity_2, quantity_3 etc so i have also tried

$_POST['quantity_'.$My_Variable]

..

 

but no luck, any tips?

Try this:

$phpcode=eval('$myvar=$_POST[\'$My_Variable\'];');

nope no luck, i changed it to this so i can tell if it works.. any more ideas?

 

if (eval('$_POST[\'$qtyField\'];') > 0)   {
    echo "It is bigger than 0";
}

 

i tried it without the semicolon but no luck there either

$_POST['quantity_'.$My_Variable]

 

That is perfectly valid, as long as $My_Variable is 1, 2, 3, etc.

You're the one who posted that, and you said it didn't work...

..worked now..

 

i know, must have been something else that was wrong, half my code is commented out so i'm going through it now trying to work out where my error is, thanks for your help though i didn't know it was that easy, i was just taking a stab in the dark.
