Hey everyone, I posted a topic earlier that helped my previous problem by using $_SESSION instead of $_COOKIE But when I enter the correct verification number it's still saying that I entered the wrong one. I went to a website and generated a random MD5 hash with random text, is this what I'm supposed to do?

Ben burada ne yanlış var ama ne var hiçbir ipucu var:

HTML Form:

<form id="ajax-contact-form" action="javascript:alert('success!');">
<label>Name:*</label><INPUT class="textbox" type="text" name="name" value=""><br />

<label>E-Mail:*</label><INPUT class="textbox" type="text" name="email" value=""><br />

<label>Telephone:</label><INPUT class="textbox" type="text" name=telephone" value="" /><br />

<INPUT class="textbox" type="hidden" name="subject" value="Contact Form" >

<label>Message:*</label><TEXTAREA class="textbox" NAME="message" ROWS="5" COLS="25"></TEXTAREA><br />
<tr>
<label>Image  Verification:*</label>
        <input type="text"  name="verify" style="width:200px;" /><img src="verification.php?<?php echo rand(0,9999);?>" width="50"  height="24" align="absbottom" />


<label>&nbsp;</label><INPUT class="button" type="submit" name="submit" value="Send Message">
