I edit the file "register.php" and put the Security Code Check In it just look like the file I  uploaded.
The file saved the Security Code into $_SESSION['SafeCode'],need I destroy it when it invalid?

I put

Code: [Select]

array('safecode'),after

Code: [Select]

array('input', 'email', $lang_register_php['email'], 255),
and put this to display Security Code

Code: [Select]

case 'safecode':
    echo <<<EOT
    <tr><td width="40%" class="tableb"  height="25">
        <script language="javascript">
function startRequest(){
$("#re").load("ajaxcheckcode.php?safecode="+$("#safeccc").val());
}
</script>
            Security Code:<span style="font-size:10px">(click to refresh)</span><img src=ajaxcode.php onclick="this.src='ajaxcode.php?nocache='+Math.random()" style="cursor:hand"/></td>
        <td width="60%" class="tableb" valign="top">
        <input type=text name=safecode id=safeccc style="width:80px" onBlur="startRequest()"><span id=re style="padding-left:30px;font-size:12px"></span>
        </td></tr>
EOT;
    break;after

Code: [Select]

foreach ($form_data as $element) switch ($element[0]) {
put thw code to check the Security Code

Code: [Select]

session_start();
if ((get_post_var('safecode') != $_SESSION['SafeCode']) or ($_SESSION['CodeTime']<time())){
$error = '<li>' . 'Security Code Wrong';
return false;
}after

Code: [Select]

$result = cpg_db_query($sql);
The file I used has uploaded.

Ask the person you got your "securitycode" hack from. It's not part of Coppermine, so how are we suppossed to know what that hack does and what it takes to make it work.
What is that piece of code suppossed to do? Is it some sort of captcha hack? If yes, use the captcha mod or plugin that is being discussed here on our site. If you insist on using a third-party hack that doesn't come from this site, you're on your own.
