[SOLVED] security image

[fazzfarrell]

Hi I have found some code for a php form, with a sectrity image which works fine as this:

 

</code>

<?php

      // check for posted form

      if (isset($_POST['login'])) {

        // see if the code the user typed matched the generated code

        if (strtoupper($_POST['code']) == $_SESSION['code']) {

            echo 'Congratulations, you entered the correct code.';

        } else {

            echo 'You have entered the wrong code. Please <a href="contact2.php">try again</a>.';

        }

      } else {

  ?>

  <form method="post" action="contact2.php">

      <fieldset>

        <legend></legend>

        <label for="Name">

Send to:

<select name="Email" id="Email">

  <?php

do { 

?>

  <option value="<?php echo $row_rsContact['EMail']?>"><?php echo $row_rsContact['Manager']?></option>

  <?php

} while ($row_rsContact = mysql_fetch_assoc($rsContact));

  $rows = mysql_num_rows($rsContact);

  if($rows > 0) {

      mysql_data_seek($rsContact, 0);

  $row_rsContact = mysql_fetch_assoc($rsContact);

  }

?>

</select>

<br />

        <br />

        Name:</label>

        <input type="text" name="Name" id="Name" value="" />

        <label for="Email">Email:</label>

        <input type="text" name="EMail" id="EMail" value="" />

        <label for="Subject">

        Subject:</label><input type="text" name="Subject" id="Subject" value="" />

        <label for="Subject">

        Message:</label>

        <textarea name="Message" rows="10" id="Message"></textarea>

        <div id="security"><img src="../security-image.php?width=144" width="144" height="30" alt="Security Image" /></div>

        <label for="code">Security Image:</label>

        <input type="text" name="code" id="code" value="" />

      <input type="submit" name="login" id="login" value="Login" />

      </fieldset>

  </form>

  <?php

      }

  ?><code>

Here is my contact form

<?
// Change to your own email address
$your_email = "[email protected]";

// This is what is displayed in the email subject line
// Change it if you want
$subject = "Message via your contact form";

// This is displayed when the email has been sent
$thankyou_message = "<p>Thankyou. Your message has been sent.</p>";

$self = $_SERVER['REQUEST_URI'];

$name = $_POST['txtName'];
$email = $_POST['txtEmail'];
$message = $_POST['txtMessage'];
$send = $_POST['send'];

$msg="<p>Please fill in this form if you have any queries or suggestions.</p>";

echo ($msg);

$form = "
    <form method=\"post\" action=\"$self\">

    <p><label for=\"txtName\">Name:</label>
    <input type=\"text\" title=\"Please enter your name\" id=\"txtName\" name=\"txtName\" size=\"40\" value=\"$name\" /></p>

    <p><label for=\"txtEmail\">Email:</label>
    <input type=\"text\" title=\"Please enter your email address\" id=\"txtEmail\" name=\"txtEmail\" size=\"40\" value=\"$email\"/></p>

    <p><label for=\"txtMessage\">Comments:</label>
    <textarea title=\"Please enter your message\" id=\"txtMessage\" name=\"txtMessage\" rows=\"20\" cols=\"45\">$message</textarea></p>

</form>";

if($send)
{
    $valid=true;

if( !$name )
{ 
    $errmsg.="Please enter your name:<br />";
    $valid=false;
}

if( !$email )
{
    $errmsg.="Please enter your email address:<br />";

}

if (empty($_POST['verify']) && $_POST['verify'] == $_SESSION['captchstr'])
{
    $errmsg.="Please enter security image:<br />";
    $valid=false;
}
}

if( $valid !=true )
    {
echo( "<span style=\"font-weight: bold; color:red;\">".$errmsg."</span>" . $form );
    }

else {

    // Stop the form being used from an external URL
    // Get the referring URL
    $referer = $_SERVER['HTTP_REFERER'];
    // Get the URL of this page
    $this_url = "http://".$_SERVER['HTTP_HOST'].$_SERVER["REQUEST_URI"];
    // If the referring URL and the URL of this page don't match then
    // display a message and don't send the email.
    if ($referer != $this_url) {
        echo "You do not have permission to use this script from another URL.<br />";
echo "If you are behind a firewall please check your referrer settings.";
        exit;
    }

    // The URLs matched so send the email
    if( mail($your_email, $subject, $message, "From: $name <$email>"));
    {
    	// Display the thankyou message
    	echo $thankyou_message;
    }
}
?>

 

You need session_start() at the top of the page as always and you need to upload the arial.ttf to the same directory as this next bit that creates the securty image

 

 

save this as captcha.php (i store this in a folder called includes with the arial.ttf)

<?php
session_start();
$strlength = rand(4,7);
$captchastr = "";
for($i=1;$i<=$strlength;$i++)
{
$textornumber = rand(1,3);
if($textornumber == 1)
{
$captchastr .= chr(rand(49,57));
}
if($textornumber == 2)
{
$captchastr .= chr(rand(65,78));
}
if($textornumber == 3)
{
$captchastr .= chr(rand(80,90));
}
}
$randcolR = rand(100,230);
$randcolG = rand(100,230);
$randcolB = rand(100,230);

//initialize image $captcha is handle dimensions 200,50
$captcha = imageCreate(190,50);
$backcolor = imageColorAllocate($captcha, $randcolR, $randcolG, $randcolB);

$txtcolor = imageColorAllocate($captcha, ($randcolR - 60), ($randcolG - 60), ($randcolB - 60));
for($i=1;$i<=$strlength;$i++)
{

$clockorcounter = rand(1,2);
if ($clockorcounter == 1)
{
$rotangle = rand(0,45);
}
if ($clockorcounter == 2)
{
$rotangle = rand(315,360);
}

//$i*25 spaces the characters 25 pixels apart
imagettftext($captcha,rand(14,20),$rotangle,($i*25),30,$txtcolor,"/arial.ttf",substr($captchastr,($i-1),1));
}
for($i=1; $i<=4;$i++)
{
imageellipse($captcha,rand(1,200),rand(1,50),rand(50,100),rand(12,25),$txtcolor);
}
for($i=1; $i<=4;$i++)
{
imageellipse($captcha,rand(1,200),rand(1,50),rand(50,100),rand(12,25),$backcolor);
}
//Send the headers (at last possible time)
header('Content-type: image/png');

//Output the image as a PNG
imagePNG($captcha);

//Delete the image from memory
imageDestroy($captcha);

$_SESSION["captchastr"] = $captchastr
?>
