Send PHP form via SMTP - php

Question

I've found some similar questions to my query, but none that fully match my situation.
I had a basic mail() PHP setup for use on the contact form on my website but, turns out this is blocked on my hosting server to avoid spam/abuse.
The web host recommends using SMTP as a workaround, but the tutorial they link to doesn't seem to provide a working solution for me!
This is my HTML:
<form action="php/mail.php" method="POST">
<p class="form-field-title">Name</p>
<input class="contact-field focus-hide" type="text" id="name" name="name" required autocomplete="off">
<p class="form-field-title">Email Address</p>
<input class="contact-field focus-hide" type="email" id="email" name="email" required autocomplete="off">
<p class="form-field-title">Phone</p>
<input class="contact-field focus-hide" type="text" id="number" name="number" autocomplete="off">
<p class="form-field-title">Message</p>
<textarea class="contact-field focus-hide" id="message" name="message" data-gramm_editor="false" required autocomplete="off"></textarea>
<input class="contact-button" type="submit" value="Send Message">
</form>
And this is my original (non-SMTP) mail.php code:
<?php
$name = $_POST['name'];
$email = $_POST['email'];
$number = $_POST['number'];
$message = $_POST['message'];
$formcontent="Name: $name \nEmail: $email \nPhone Number: $number \nMessage: $message";
$recipient = "email#email.com";
$subject = "Website Contact Form Enquiry";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
header('Location: ../thanks.html');
exit();
?>
I have the email server details for my web hosting, but none of the SMTP solutions I've found are working for me!
Is anyone able to help me? I've seen a few things about using PEAR, but their website doesn't seem to be working...?
Thanks!

Answer 1

If your form is in an email, I think you can't post data (maybe I'm wrong). But you can send it to your script with method get.
<form action="php/mail.php" method="GET">
</form>
Then update your php :
<?php
$name = $_GET['name'];
$email = $_GET['email'];
$number = $_GET['number'];
$message = $_GET['message'];
$formcontent="Name: $name \nEmail: $email \nPhone Number: $number \nMessage: $message";
$recipient = "email#email.com";
$subject = "Website Contact Form Enquiry";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
header('Location: ../thanks.html');
exit();
?>
It should do the job.
