    Hello sytu,

    Thank you for posting your inquiry.

    Unfortunately, you cannot add PHP codes in the form. The best way to do this is get the source code of your form that you have created here and place it inside your webpage.

    To get the source:

    1. Edit your form, go to Setup & Embed tab and click Embed Form

    2. An embed form wizard will appear.  Under Display it on your site, click Source

    3. Copy the code on the next page

    4. Or you can click on the link to download the zipped file with the .css and .js files

    Let us know if you need more explanation regarding this matter.

    I just noticed now that you also have set a mailer on your code.

    On Jotform, you won't need that mailer code.  You only have to add an auto responder.

    To add an auto responder:

    1. Click on "Setup and Embed" tab on the form builder toolbar         
    2. Click on "Email Alerts"
    3. Click on "Add New Email"
    4. Select "Autoresponder" option, click "Next" and complete the wizard.

    Sorry, I got confused with the process that you wanted to use with your form.  Unfortunately, you cannot make a process validation via PHP with using Jotform.  What you can do is convert your code to Javascript.

    Hope this helps.
