I'm trying to redirect to a .php page if the $validForm variable is TRUE.
Here's my code:
<?php session_start();
require("validationLibrary.php");
$validForm = true;
?>
<html>
<head>
<title>Registration Form - 1 of 2</title>
</head>
<body>
<h1>Registration - Part 1 of 2</h1>
<p>Please fill in all the required information before submitting the information.</p>
<form action="registerFormOne.php" method="post">
<dt>First Name:</dt>
<dd><input type="text" name="firstName" /></dd><br />
<dd>
<?php
if(isset($_POST['firstName'])){
if(!validateRequired($_POST['firstName'])){
$validForm = false;
}
}
?>
</dd><br />
<dt>Last Name:</dt>
<dd><input type="text" name="lastName" /></dd><br />
<dd>
<?php
if(isset($_POST['lastName'])){
if(!validateRequired($_POST['lastName'])){
$validForm = false;
}
}
?>
</dd><br />
<dt>EMail:</dt>
<dd><input type="text" name="email" /></dd><br />
<dd>
<?php
if(isset($_POST['email'])){
if(!validateEmail($_POST['email'])){
$validForm = false;
}
}
?>
</dd><br />
<dt>Age:</dt>
<dd><input type="text" name="age" /></dd><br />
<dd>
<?php
if(isset($_POST['age'])){
if(!validateNumber($_POST['age'])){
$validForm = false;
}
}
?>
</dd><br />
<dt>Date of Birth:</dt>
<dd><input type="text" name="dateOfBirth" /></dd><br />
<dd>
<?php
if(isset($_POST['dateOfBirth'])){
if(!validateRequired($_POST['dateOfBirth'])){
$validForm = false;
}
}
?>
</dd><br />
<dt>Gender:</dt>
<dd>Masculino <input type="radio" value="M" name="gender" checked/>
Femenino <input type="radio" value="F" name="gender" />
</dd>
<dt><input type="submit" /></dt>
<?php
if($validForm = true){
header("Location: registerFormTwo.php");
exit;
}
?>
</form>
</body>
</html>
I'm getting this error:
Warning: Cannot modify header information - headers already sent by (output started at C:\XAMPP\xampp\htdocs\registerFormOne.php:18) in C:\XAMPP\xampp\htdocs\registerFormOne.php on line 84
