Form Checking

Egri

Ok I'm totally lost. And I'm probably doing this totally wrong, but I guess thats why learning is so good. If anyone can help me out with this I would be very Thankful

Page 1

<html>
  <head>
    <title>PHP Test</title>
  </head>
  <body>

<form action="action.php" method="post">
 <p>Pick a number 1 -5 : <input type="text" name="expression" /></p>
 <p><input type="submit" /></p>
</form>


  </body>
</html>

Page 2

<html>
  <head>
    <title>PHP results</title>
  </head>
  <body>

<?php
$express = "5"

if (strpos($_POST['$expression'], $express) != false) { 
   ?>
    <strong>This is true.</strong>
   <?php 
} else { 
   ?>
    <strong>This is false.</strong>
   <?php 
}
?>

  </body>
</html>

I have a feeling that my lack of knowledge is why I can't figure this out, and there is probably a large ammount of code that would be needed to do this. But if its something simple could you please point out what I'm doing wrong. If its some complex code then just let me know and disregard. I am tring the small stuff first, but its kicking my butt, so I don't want to get to far ahead of myself. Thanks in advance.

Edit : On a side note I don't think strpos() is the correct command to do this in the first place, but I could be wrong.

Can i ask what the script is actually doing?? 😕

Page 1 is letting the user input a number 1-5

Page 2 is suppose to be calling the $expressions and matching it with $express

if they match it print "thats true" if they don't it prints thats false.

I guess is the easiest way to explain it.

can't you just have

if($_POST['expression'] ==$express)
{
stuff iff true;
}
else
{
stuff if false;
}

also on your first page would it not be better to let the user pick from a menu the options between 1-5 rather than enter them?

Egri

that didn't work. So unless I haven't learned to copy and paste then. 🙁

I know that it is probably simple, but I can't figure it out. Thanks for the attempt.

What I posted wouldn't work on its own.

Try

<html>
<head>
<title>PHP results</title>
</head>
<body>

<?php
$express = 5;
$expression = $_POST['expression'];

if ($express == $expression) {
{
echo'That's true';
}
else
{
echo'That's false';
}
?>

</body>
</html>
