Question

index.php:

<form action="post.php" method="POST">
  <input type="text" name="option_<?php echo $i ?>" value="" />
  <input type="submit" name="btnSubmit" value="submit">
</form>

The $i variable is a sequence running from 1 to $n.

post.php:

if(isset($_POST['btnSubmit']))
{
  $option_name = ???;
}

How do I get the text that was posted for each option?

Answer 1

Why not use PHP arrays for this?

<form action="" method="POST">
 <input type="text" name="option[]" value="" />
 <input type="submit" name="btnSubmit" value="submit">
</form>

In the file it is posted to:

if(isset($_POST['btnSubmit']))
{
   foreach ($_POST['option'] as $i => $value)
   {
       echo "Option $i is $value\n";
   }
}
