Free Contact Form for PW?

[welski]

Is there a free way for me to add a contact form in my PW site?

As far as I know I should buy the form builder module for that? 

[horst]

There is a module in the directory, called "Simple Contact Form".

You can also keep an eye on https://processwire.com/talk/topic/10929-developer-centric-form-processor/ (still in Alpha)

I haven't had a chance to use it but it seems very promising.

Or a custom Hanna Code approach ...

If you are into coding - Things surely need to be changed to fit your needs, I hope one gets the idea.

Hanna Code of one contact form:

<?php
$form = $modules->get("InputfieldForm");
$form->action = "{$page->url}"."#contact-form";
$form->method = "post";
$form->attr("id+name",'contact-form');

// create name field
$field = $modules->get("InputfieldText");
$field->label = "Name:";
$field->attr('placeholder', 'Enter name here please');
$field->attr('id+name','cf_name');
$field->required = 1;
$form->append($field);

// create email field
$field = $modules->get("InputfieldEmail");
$field->label = "E-Mail:";
$field->attr('placeholder', 'Enter E-Mail address here please');
$field->attr('id+name','cf_email');
$field->required = 1;
$form->append($field);

// create HONEYPOT email field
$field = $modules->get("InputfieldEmail");
$field->label = "Anti-Spam field! Dear screenreader user. Please leave this field out since it serves as spam detection. Otherwise your message will get lost!";
$field->attr('placeholder', 'Leave this field empty! Spam-protection!');
$field->attr('id+name','email');
$field->required = 0;
$form->append($field);

// create textarea field
$field = $modules->get("InputfieldTextarea");
$field->label = "Your Message:";
$field->attr('placeholder', '');
$field->attr('id+name','cf_text');
$field->required = 1;
$form->append($field);

// oh a submit button!
$submit = $modules->get("InputfieldSubmit");
$submit->attr("value","Senden");
$submit->attr("id+name","cf_submit");
$form->append($submit);

if ($input->post->cf_submit) {
    $form->processInput($input->post);
    // honeytrap
    if($form->get("email")->value != "") {
        echo "spam!spam!spam!";
        die();
    }
    if($form->getErrors()){
        echo $form->render();
    } else {
        $add_header = 'From: '.$form->get("cf_email")->value."\r\n".'Reply-To:'.$form->get("cf_email")->value."\r\n".'X-Mailer: PHP/'.phpversion();

        $mailmessage = "A message from: \n\n";
        $mailmessage .= $form->get("cf_name")->value."\n";
        $mailmessage .= $form->get("cf_email")->value."\n\n";
        $mailmessage .= $form->get("cf_text")->value;

        $mail_goes_to = "whereitgoes@somewhere.com";

        mail($mail_goes_to, "enter subject here", $mailmessage, $add_header);
        echo "<p id='contact-form'><span style='background:yellow;'>Message successfully sent!</span></p>";
    }
} else {
    echo $form->render();
}

Interesting approach @blynx

[benbyf]

I just have a custom php form in the pw templates

The only thing I would add to blynx's approach would be to add a CSRF token to the form so it can only be submitted once rather than someone spamming the Submit button - more on that here: https://processwire.com/talk/topic/3633-prevent-form-resubmission/?p=35585

Other than that I use almost the exact same approach in some of my own forms.

EDIT: Oh, and so you don't get stuck with the default form styles/classes/markup: https://processwire.com/talk/topic/2089-create-simple-forms-using-api/?p=39436

To partly contradict Pete's suggestion. Following to this post are arguments on why one shouldn't necessarily use the csrf field to prevent multiple submissions: https://processwire.com/talk/topic/3779-use-csrf-in-your-own-forms/?p=103334 But you should still use the field to prevent csrf attacks.

Also usage of wireMail() class instead of mail() function.

Yup - you're right. There are methods on the one I linked to (further up I think) to stop multiple submissions with JS: https://processwire.com/talk/topic/3633-prevent-form-resubmission/?p=35551 so not sure why I confused the issue with CSRF.

The main thing is to play it safe you should use CSRF to make sure the form is submitted securely as well as some code to stop multiple submissions (ideally client side and server side, but at the very least server side as obviously JS can be disabled in the browser).
