I can't explain in title ...

[Pazza]

Basically, I am looking for a code where say...

There is an input box, and you must enter a certain code to proceed to the next page. So say the code was 123, if u typed 29475 it would say something like 'unfortunately, your code is incorrect'.

I'm needing it for a competition at school

+rep for help

[Protege]

image verification basically?

[Kieran]

But number verification

Basically a code could be:

Randomly generate number
Check if number entered = number displayed
If yes, proceed
If no, dont proceed

In a nutshell.

[Pazza]

Yeah, basically. But the code wouldn't be shown ...

And I don't know PHP

Im seriously tired I've coded 13 hours straight =/ but I'll give it ago. You need like a small jpeg and call it image.jpg - we'll use this to put the numbers on.

Call that, whatever.html

<form method="post" action="page.php">
<img src="image.php"><br>
<b>Image text:</b> <input type="text" name="image"><br>
<input type="submit" value="SUBMIT">
</form>

Call this image.php (same directory as wwhatever.html)

<?php
session_start();
$numbers = "1234567890";
$random = substr(str_shuffle($numbers), 0, 10);
$_SESSION["image"] = $random;
$image = imagecreatefromjpeg("image.jpg");
$textColor = imagecolorallocate ($image, 255,000,000);
imagestring ($image, 3, 15, 1, $random, $textColor);
imagejpeg($image);
imagedestroy($image);
?>

Call this page.php

<?php
session_start();
// cheap and nasty php you get theidea
if($_POST["image"] == $_SESSION["image"]) {
 echo("yay you got it right");
} else {
 echo("you got it wrong, you fail.");
}
session_destroy();
?>

you can use my image btw

Should work

<?php

if($_GET["act"] == "submit")
    {    
        $entry = ($_POST["entry"]);
        $answer = ($_POST["rand"]);
        
        if($entry == $answer)
        {
        echo("Well Done! You got it right. The answer was $answer.. you can replace this with the form or what ever.");
        } else {
        echo("Ohh Noes! You got it wrong.. lol");
    }
    }
    else 
    {
        $rand = rand();
        echo("Please enter the following number in the box below:<br>$rand<br>
        <form method=\"post\" action=\"?act=submit\">
        <input readonly type=\"hidden\" name=\"rand\" value=\"$rand\">
        <input type=\"text\" name=\"entry\"><br><br>
        <input type=\"submit\" value=\"Submit\">
        </form>");
    }
?>

I kinda cheated by making a textbox store the code.

Its only a competition at school..

[Pazza]

Yeah, for this enterprise evening.

So in Jacks code,

Do I specify a code, and that code is the only one accepted. So, basically the page will just be a box to type the code in, and a submit button. If I say the code is 123, if 123 is entered it will redirect to another page saying congrats you won bla bla bla. If it is the wrong one it will say sorry, you have lost. I don't mean there is a code shown, but 123 would be the only code that could be accepted ??
