JVís Power Tips for PHP (2) - Method 1
(Page 3 of 7 )

Anyway, back to the main point. We are in the middle of writing a script to test if the user has selected bold, italic etc. Here is the first (most basic) way of doing this:

<?php

  if ( $_POST['bold'] )
  {
    $_POST['chat'] = "<b>{$_POST['chat']} </b>";
  }

  if ( $_POST['italic'] )
  {
    $_POST['chat'] = "<i>{$_POST['chat']}</i>";
  }

  if ( $_POST['underline'] )
  {
    $_POST['chat'] = "<u>{$_POST["chat']}</u>";
  }

  if ( $_POST['strike'] )
  {
    $_POST['chat'] = "<s>{$_POST['chat']}</s>";
  }

  echo $_POST['chat'];

?>


It's easy to see what is going on here. So I wonít say too much about it. Except that it is worth noting the variable $_POST['chat'] is within {}'s. This means you donít have to break the "'s with .s!
