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?
CYA, Dave
