Call a PHP function after onClick HTML event

Question

Purpose: Call a PHP function to read data from a file and rewrite it. I used PHP only for this purpose - FileIO - and I\'m new to PHP.

You don't need javascript for doing so. Just delete the onClick and write the php Admin.php file like this:

alert('Data not existed!')";
        } 
    else{
        $contact_list = $contact_list . addNewContact();
        file_put_contents("data/data.json", $contact_list);
        }
    fclose($datafile);
    }

// Call the function saveContact()
saveContact();
echo "Thank you for joining us";
}
else //If the form is not submited or not all the required fields are filled

{ ?>


    

        
Add New Contact
         

         

         

        
        
    

Thought I don't like the PHP bit. Do you REALLY want to create a file for contacts? It'd be MUCH better to use a mysql database. Also, adding some breaks to that file would be nice too...

Other thought, IE doesn't support placeholder.
