Simple form to email example
Inspired by http://drupal.org/node/197092 I decided to write a short snippet to demo how to take a simple form field, validate it and send the field to an email address on submission.
Like the above post, this snippet just asks for an email address with a submit button. Validation just checks the email address syntax.
This is really meant as a "starting point", it's up to you, the reader, to add bells and whistles as required.
To use this snippet, create a new block. Cut'n'paste the code below and set the blocks input filter to "PHP". Then place the block somewhere to use it.
<?php
$send_form_to = 'jdow@example.com'; // Change this!
function my_sign_up_form() {
$form['email'] = array(
'#type' => 'textfield',
'#title' => '',
'#size' => '20',
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => 'Subscribe',
);
return $form;
}
function my_sign_up_form_validate($form_id, $form) {
if (!valid_email_address($form['email'])) {
form_set_error('email', 'Your email address appears malformed');
}
}
function my_sign_up_form_submit($form_id, $form) {
$message = 'New signup email address: '. $form['email']; // Body of your email here.
drupal_mail('my_sign_up_form', $send_form_to, 'New signup', $message, variable_get('site_mail', 'an@example.com'));
drupal_set_message('Thank you for signing up to our email alerts'); // Your thank you message here
}
return drupal_get_form('my_sign_up_form');
?>btw, the above is a basic starting point and does not include any filtering so you are advised to see the handbook section on writing secure code
Thank you for writing this
Thank you for writing this snippet.
I could not get it to function in a block on my 5.9 installation as written. I simplified it by removing variables the following way and it works like a charm:
<?php
function my_sign_up_form() {
$form['email'] = array(
'#type' => 'textfield',
'#title' => '',
'#size' => '20',
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => 'Subscribe',
);
return $form;
}
function my_sign_up_form_validate($form_id, $form) {
if (!valid_email_address($form['email'])) {
form_set_error('email', 'Your email address appears malformed');
}
}
function my_sign_up_form_submit($form_id, $form) {
$message = 'New Email List address: '. $form['email'];
drupal_mail('my_sign_up_form', 'an@example.com', 'New Email List Signup', $message, 'email_list@example.com');
drupal_set_message('Thank you for signing up to our email list!');
}
return drupal_get_form('my_sign_up_form');
?>
Not sure why the variables were giving me troubles....
