Weaving Dream Dedecms website to customize the form plus Dede template to bring the verification code method.

Sometimes we prevent malicious filling out of form submissions because we need to add a verification code to a custom form for the Dede site.

We can use the following methods to achieve:

First, we're going to find/plus/diy.php this file.

Introduce files in the head:

Require_once (dedeinc. ' /membermodel.cls.php ');

And then find

ElseIf ($do = = 2)

{Add code blocks to this place

Verification Code Verification

$svali = Getckvdvalue ();

if (Preg_match ("/1/", $safe _gdopen)) {

if (Strtolower ($vdcode)! = $svali | | $svali = = ")

{

Resetvdvalue ();

ShowMsg (' Verification code Error! ', '-1 ');

Exit ();

}

}

Save the file after you have modified it.

Step two: Insert a code block in a custom form static page that uses a CAPTCHA

<input type= "text" class= "Intxt w200" style= "width:50px; text-transform:uppercase; "id=" Vdcode "name=" Vdcode "class=" code "/>

can't see clearly?

In this static page, you still have to quote jquery.

Add JS code block again

<script type= "Text/javascript" >
$ = jQuery;
function Changeauthcode () {
var num = new Date (). GetTime ();
var rand = Math.Round (math.random () * 10000);
num = num + rand;
$ (' #ver_code '). CSS (' visibility ', ' visible ');
if ($ ("#vdimgck") [0]) {
$ ("#vdimgck") [0].SRC =]: /include/vdimgck.php?tag= "+ num;
}
return false;
}
</script>

OK, now try, is it possible to implement the verification code submission? A simple dedecms custom form dede template comes with a verification code function.

Generally encounter a 172th line of error, because a "}" only need to add one on line 172 OK.
