I'm learning some more PHP and after PHP itself to work, I can't seem to get it to validate any form field correctly. My goal is to check if the firstname field is empty, and if it is, it will give a message in a red color. The message in the red works, but only because the echo script is being called by the form submission, not because it has detected any empty field, because when I made an else statement to say "wassup" if its not empty, I got the same message for when the field is empty. Also, is there a way to check off multiple input fields at once like you could with JavaScript? For example if input1 == '' || input2 == '' and so on. Here is my HTML:
<html>
<head>
<title>Welcome</title>
</head>
<body>
<form action="welcome.php" method="post">
<fieldset>
<legend>Personal Info</legend>
First name <input name="name" type="text">
Middle name <input name="middlename" type="text">
Surname <input name="lastname" type="text">
Age <input name="age" type="number">
Date of birth <input name="dob" type="date">
</fieldset>
<fieldset>
<legend>Regional & location info</legend>

<select>
<option value="europe">Europe</option>
<option value="americas">America</option>
<option value="africa">Africa</option>
<option value="asia">Asia</option>
<option value="australia">Australia</option>
<option value="eurasia">Eurasia</option>
</select>
Country <input name="country" type="text"> State <input type="text">
City <input name="city" type="text">
Street number <input name="streetno" type="number">

<input name='signiture' type="text">

<input type="submit" name="submit" value="Submit">

</html>
Here is my PHP code:
<?php
$firstname = $_POST['name'];
$lastname = $_POST['lastname'];
$age = $_POST['age'];
$dob = $_POST['dob'];
$country = $_POST['country'];
$city = $_POST['city'];
$suburb = $_POST['suburb'];
$postcode = $_POST['postcode'];
$streetno = $_POST['streetno'];
$streetname = $_POST['streetname'];
$suburb = $_POST['suburb'];
$job = $_POST['job'];
$school = $_POST['school'];
$reason = $_POST['reason'];
$arrival = $_POST['arrival'];
$signiture = $_POST['signiture'];
if (isset($_POST['submit'])) {
if (empty($_POST[$firstname])) {
echo '<p style="color: red; text-align: center">Your first name is required</p>';
} else {
echo "wassaup";
}
}
?>
