help w/ $_POST in PHP

Outer · 02-23-2005, 06:56 PM

Heres my problem, I have a bunch of variables sent from a form that takes on the look:

planet1
planet2
planet3
planet4
planet5
ect.
ect.
ect.

heres the IF statement that it is sent to:

PHP Code:

  IF ($_POST[Submit] == "Submit") {

????: NamePros.com http://www.namepros.com/programming/71755-help-w-_post-in-php.html
   for ($a = "1"; $a <= "380"; $a++) {

     $planet = $_POST[planet$a];

 
   }

}

I get the error: Parse error: parse error, unexpected T_VARIABLE, expecting ']' in www\hyps\allocation_map.php on line 24

so, my question to you is, how do I have the variable $a inside of the _POST variable?

Put single quotes around the post variable:

PHP Code:

  $_POST['planet$a'];

To be honest the best way going about doing this would be to set the names to planet[] rather than planet1, ect. This will create an array of all the input and would make everything much easier to maintain.
