26 Jul Captcha php coding question Posted by Liesl van Dalen | 6 Comments
I need to add a capthca to our online forms and I did the things as mentioned on the following site page: http://www.phpjabbers.com/captcha-image-verification-php19-5.html#comments

But i do not know where in my php code section to add the capthca php code section. When this form is working I will implement the changes to the Admissions contact us page. The relevant page I am currently working on is: http://www.aisj-jhb.com/Winter%20School/WinterSchoolContactUs.html

I also want to make the capthca a required field in the form as currently it actually send the form even if I did not add/inserted the capthca.

Thank you for your assistance in this matter I really do appreciate it.

Here is the relevant php code:

The IF statement which checks if the captcha is correctly entered or not should be placed before

$success = mail($EmailTo, $Subject, $Body, $headers);

So that line will only execute if the captcha is correct.

Hi Mark,

I did what you said in your comment and I testing the form by deliberately entering the incorrect captcha. Yet the form still submitted the information. So there is obviously still a problem with my code somewhere.

This is the new php code after incorporating your comment:
<?php

.....



$headers = $emailFromToUse."rn";



// send email 

//$success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>");

session_start();

if ($_POST["vercode"] != $_SESSION["vercode"] OR $_SESSION["vercode"]=='')  {

     echo  '<strong>Incorrect verification code.</strong>';

} else {

     // add form data processing code here

     echo  '<strong>Verification successful.</strong>';

}; 



$success = mail($EmailTo, $Subject, $Body, $headers);



// redirect to success page 

if ($success){

  //print("OK");

 	print "<meta http-equiv="refresh" content="0;URL=WinterSchool_ok.html">";

}

else{

  //print("FAIL");

  	print "<meta http-equiv="refresh" content="0;URL=WinterSchool_error.html">";

}

/**/

//This sends a confirmation to your visitor

mail ("$Email","Thank You for visiting $sitename", 

"Hi $First_Name,n

Kind Regards,

$sitename

$siteaddress","From:$sitename") ;

Thank you Mark, my form works now :)
Just one more question: how can I make my captcha be a mixture of numbers and alphabet letters?

I know that in order to change that I need to work in the captcha php file.

Thank you for your assistance in this.
