How do I send email with multiple form fields in php - php

Question

I want to send email from the contact form on my site that has multiple form fields. But I can't seem to get that right.
Here is my form HTML code:
<form class="form-horizontal" action="mail.php" method="post">
<h2>Quick Contact</h2>
<div class="form-group">
<label class="control-label col-sm-2" for="email">Full Name:</label>
<div class="col-sm-6">
<input type="text" class="form-control" id="fname" placeholder="Enter Full Name" name="fname">
</div>
</div><br>
<div class="form-group">
<label class="control-label col-sm-2" for="num">ID Number:</label>
<div class="col-sm-6">
<input type="text" class="form-control" id="num" placeholder="Enter ID Number" name="id">
</div>
</div><br>
<div class="form-group">
<label class="control-label col-sm-2" for="email">Email:</label>
<div class="col-sm-6">
<input type="email" class="form-control" id="email" placeholder="Enter Email Address" name="email">
</div>
</div><br>
<div class="form-group">
<label class="control-label col-sm-2" for="sal">Monthly Salary:</label>
<div class="col-sm-6">
<input type="number" class="form-control" id="sal" placeholder="Enter Salary" name="salary">
<div class="label label-warning" >Numbers only. Any other characters are not permitted.</div>
</div>
</div><br>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-danger">Submit</button>
</div>
</div>
</form>
This is my PHP code, I am using PHP mail() to send the email:
<?php
$to = 'mail#gmail.com';
$subject = 'Loan Request';
$from = $_POST['email']; // required
$name = $_POST['fname']; // required
$id = $_POST['id']; // required
$telephone = $_POST['mobile']; // not required
$salary = $_POST['salary']; // required
$message = $name." ".$telephone." ".$salary;
$headers = 'From: '.$from."\r\n".
'Reply-To: '.$from."\r\n" ;
// Sending email
if(mail($to, $subject, $from, $message)){
header('Location: http://example.com');
} else{
echo 'Unable to send email. Please try again.';
}
?>
The mail delivers quite alright, but does not display the entire form details when it enters my email. I will like to know how I can capture all the form fields cos I intend to add more form fields. It's a really long form.

Answer 1

If you are using PHP's mail function then the parameters should be in this order. In your example the $headers parameter was not passed at all.
if (mail($to, $subject, $message, $headers)) {
header('Location: http://example.com');
} else {
echo 'Unable to send email. Please try again.';
}

Answer 2

first ensure ur localhost/server is configured to send email
use the following function to send email (works for me)
public function email($to,$cc,$from,$subject,$message){
$config['protocol']='mail';
$config['smtp_host']='ssl://smtp.gmail.com';
$config['smtp_port']='465';
$config['smtp_timeout']='30';
$config['smtp_user']='urEmail#gmail.com';
$config['smtp_pass']='urPassword';
$config['charset']='utf-8';
$config['newline']="\r\n";
$config['wordwrap'] = TRUE;
$config['mailtype'] = 'html';
$this->load->library('email',$config);
// $this->email->initialize($config);
$this->email->from($from, 'Limecar.in');
$this->email->to($to);
$this->email->cc($cc);
$this->email->subject($subject);
$this->email->message($message);
if ($this->email->send()) {return true;}
else {return false;}
}
