Until now I used in my website which is at the moment being ported to MODx a php contact form. This form is based on two php-files: formmailer.php with the form itself and global_vars with the variables. The form-script uses a xhtml-template and includes the form-template and after sucessfully submitting the contact message a thank-you-page via php-include. I would like to use this form rather than using eform or SPForm because this form has worked for many months without having let passed any single spam-mail and I think that the concept of the confirmation-step before sending the message to prevent automatic submitting is a simpler and better way to protect the form against spammers than a captcha.
I tried to put the php-form in a snippet, but was not able to get it to run.
My problem is that I have little to no knowledge of php and am not able to change the php-variables to MODx.
I would appreciate it if someone could tell me if it is possible to use this formmailer with MODx and if yes how to change this formmailer to be usable in MODx. Explanation in an easy-to-understand way would be great.
