I am working on an online newspaper/blogging application with CodeIgniter 3.1.8 and Twig.
I have added a contact form to the application:
{% if errors %}
<div class="alert-box alert-box--error">{{errors | raw}}</div>
{% endif %}
<form name="contactForm" id="ajaxForm" class="s-content__form"
action="{{base_url}}contact"
method="post"
data-successmsg="Your message was sent. We will reply as soon as possible."
data-failmsg="Sorry, we could not deliver your message"
novalidate>
<fieldset>
<div class="form-field">
<input type="text" class="h-full-width" placeholder="Name" name="name" id="name" data-rule-required="true" value="{{set_value('name') | striptags}}">
</div>
<div class="form-field">
<input type="email" class="h-full-width" placeholder="Email" name="email" id="email" data-rule-required="true" value="{{set_value('email') | striptags}}">
</div>
<div class="form-field">
<input type="text" class="h-full-width" placeholder="Subject" name="subject" id="subject" data-rule-required="true" value="{{set_value('subject') | striptags}}">
</div>
<div class="form-field">
<textarea rows="5" class="h-full-width" placeholder="Message" name="message" id="message" data-rule-required="true">{{set_value('message') | striptags}}</textarea>
</div>
<button type="submit" class="submit btn btn--primary h-full-width" id="sendMessageButton">Send</button>
</fieldset>
</form>
{% if message_success == true %}
<div class="alert-box alert-box--success text-center">
<span class="alert-box__close"></span>
Your message was sent. We will reply as soon as possible.
</div>
{% endif %}
{% if message_fail == true %}
<div class="alert-box alert-box--error">
<span class="alert-box__close"></span>
Sorry, we could not deliver your message
</div>
{% endif %}
<div id="msgContainer" class="is-hidden alert-box alert-box--{{ message_success ? 'success' : 'error' }} text-center"></div>
The form works unless I add (extra) headers to it.
Here is the controller:
class Contact extends CI_Controller {
public function __construct() {
parent::__construct();
}
private $headers = '';
private $from = '[email protected]';
private $to = '[email protected]';
private $email_address = '';
private $name = '';
private $subject = '';
private $message = '';
private $body = '';
private $message_success = false;
private $message_fail = false;
public function index(){
$this->form_validation->set_rules('name', 'Name', 'required');
$this->form_validation->set_rules('email', 'Email', 'required|trim|valid_email');
$this->form_validation->set_rules('subject', 'Subject', 'required');
$this->form_validation->set_rules('message', 'Message', 'required');
$this->form_validation->set_error_delimiters('<p class="form-error">', '</p>');
$this->displayForm();
if($this->form_validation->run() === FALSE) {
$data['errors'] = validation_errors();
} else {
//Prepare mail
$this->subject = "Website Contact Form: " . $this->input->post('subject');
$this->name = $this->input->post('name');
$this->email_address = $this->input->post('email');
$this->message = $this->input->post('message');
$this->body = "You have received a new message from your website contact form. Here are the details:\n\nName: $this->name\n\nEmail: $this->email_address\n\nMessage:\n$this->message";
$this->headers = "From: . $this->from\n";
$this->headers .= "Reply-To: $this->email_address";
//Send mail
$this->send_mail();
}
}
public function displayForm() {
$data = $this->Static_model->get_static_data();
$data['base_url'] = base_url("/");
$data['pages'] = $this->Pages_model->get_pages();
$data['categories'] = $this->Categories_model->get_categories();
$data['tagline'] = "Contact us";
$data['errors'] = validation_errors();
$data['message_success'] = $this->message_success;
$data['message_fail'] = $this->message_fail;
$this->twig->addGlobal('contactForm',"themes/{$data['theme_directory']}/templates/contact.twig");
$this->twig->display("themes/{$data['theme_directory']}/layout", $data);
}
//mail sender method
public function send_mail() {
$config['protocol'] = 'sendmail';
$config['charset'] = 'utf-8';
$config['mailtype'] = 'html';
if(!$this->load->is_loaded('email')){
$this->load->library('email', $config);
} else {
$this->email->initialize($config);
}
$this->email->from($this->from);
$this->email->to($this->to);
//this line makes it fail
$this->email->set_header($this->headers);
$this->email->subject($this->subject);
$this->email->message($this->body);
if ($this->email->send()) {
$this->message_success = true;
} else {
$this->message_fail = true;
}
}
}
If I remove $this->email->set_header($this->headers) from the above code, the email is sent successfully. But I would rather keep it.
How do I keep the headers and make it work?
You need to put headers separately into an array and add these by a loop to the Email library:
private $headers = array();
public function index(){
...
$this->headers["From"] = " $this->from\n";
$this->headers["Reply-To"] = ": $this->email_address";
...
}
// In send_mail function:
...
foreach($this->headers as $key => $value){
$this->email->set_header($key, $value);
}
...
