Write a PHP program to accept name, address, pincode, gender information. If any
field is blank display error messages “all fields are required”.
<?php
$error = "";
$name = $address = $pincode = $gender = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$name = trim($_POST["name"]);
$address = trim($_POST["address"]);
$pincode = trim($_POST["pincode"]);
$gender = isset($_POST["gender"]) ? $_POST["gender"] : "";
// Check if any field is empty
if (empty($name) || empty($address) || empty($pincode) || empty($gender)) {
$error = "All fields are required";
} else {
echo "<h3>Submitted Information</h3>";
echo "Name: $name <br>";
echo "Address: $address <br>";
echo "Pincode: $pincode <br>";
echo "Gender: $gender <br>";
exit();
}
}
?>
