I have tried getting my contact form to work trying to update the php – with no success. I now think I should be able to get this to work by updating the JS, but of course I know about as much JS as I do PHP!
So here we go again…
I have a contact form I am using in a Bootstrap responsive single-page site. The form works just fine and sends the emails just fine. My site does not get a whole lot of traffic and I dislike the Captcha fields, so I wanted to insert a simple field for users to enter to ensure they are human. I added a simple math question. Now, I need to know how to validate that the user entered the correct math answer before the email is processed.
My form uses a contact_me.js file in combination with the jqBootstrapBalidation.js file to validate and send the form to the contact_me.php to process the email. I tried updating the PHP (with some suggestions from here) but I could not get it to work. It will always send the email through even if the math answer was entered incorrectly.
It is important to note that I did not write the code for this, I am very new to js. The form and code was supplied by startbootstrap.com templates.
Looking at the contact_me.js field, I can see that it starts off validating the fields with the jqBootstrapBalidation.js. I see it then moves down to a preventDefault and has a comment stating “prevent spam click and default submit behaviour. Is this code already preventing SPAM emails here?
If it is not, I want to force the user to input the correct answer to the math question. I added this field myself. I added the variable for the human field to the contact_me.js file (I assume I needed to do this) to get the value from the form.
Further down on the .js file it then uses ajax to post to the contact_me.php to process the email. Below this is where it looks like it further validates the fields and displays the success/error messages. Is there someplace here I can verify if the user entered the correct math equation (answer should be =5) and if it is correct, then to process the email via the contact_me.php and if the answer is incorrect then to display an error message without sending to the php and ask to try again? Below is the html, contact_me.js and the contact_me.php. Thank you so much for your help with this!
