In recent years, it has been so popular to exploit website forms for spamming purposes. It is time to take necessary measures in order not to give opportunity to the net spammers. Here, this is a patch for the default Joomla Contact component to prevent automatic form submission. It uses PHP GD library to create human-readable images and validate user whether it is an automation software or just a visitor that wants to send a feedback for you.

             Download the zip file below and unpack it to your local drive. Before upload files to your server, we are strongly recommend to back up your components/com_contact directory. After backing up, open your favourite FTP proram and connect to your Joomla root directory. Upload and overwrite all files.

            

             FAQs:

       

- Q1: I have overwritten all files successfully but it seems there are some errors displaying verification image and contact form.
- A1: Make sure your verification image (images/verify_image.php) and verification class (includes/human_verify.class.php) files are readable by public, try to change file permission chmod 644 or higher.

 

-Q2: I have already uploaded patch and  set file permissions correctly but I still can't see any image.

-A2: Make sure GD library has been enabled on your server since the image verification patch relies on PHP GD library (either 1.0 or 2.0 version). You can check this from Joomla Administration panel following System-> Sytem Info -> PHPInfo tab.
