Hi All, I've been trying to figure this out based on stuff on php.net but can't seem to get a result I need. I have an array: $formarray = array ("form1" => "var1", "form2" => "var2"); And now I'm using that array to create a form (fairly abbreviated): while (list($key, $val) = each($formarray)) { echo "$val:"; echo "<input name=\"$key\"> } What I'm looking to do is set a value in my input tag if a value has been set. That is, if this form has been submitted then the variable $form1 will contain a value (well, $POST[$form1] will but you get the idea). I want to test if $form1 has a value and if it does then I can add a value= arg in my input tag. I've got as far as working out that $$key will give me the equivalent of $form1 but how do I then work out if $form1 has a value?
