[SOLVED] Foreach error

[Northern Flame]

I created a contact form, which I have created before in almost the exact way,

but this time I'm getting an error, the error reads:

 

Warning: Invalid argument supplied for foreach() in /path/to/my/website.com/contact.php on line 40

 

Heres the script (line 40 is the line that has "foreach()" and the function pageContent() is what is displayed on the page):

<?php
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];

if(empty($name)) $errors[1] = "You forgot to fill out your name!";
if(empty($email)) $errors[2] = "You forgot to fill out your email address!";
if(empty($subject)) $errors[3] = "You forgot to fill out the subject!";
if(empty($message)) $errors[4] = "You forgot to fill out the message!";

if(!empty($errors)){
function pageContent(){
?>
<div id=content1>
			<h2>You had the following errors!</h2>
<?php 
foreach($errors as $key => $val){
echo '				<i>-'.$val.'</i><br>'."\n";
}
?>
			<form action="/contact.php" method="POST">
				Name:<br>
				<input type="text" name="name" size="20" value="<?php echo $name; ?>"><br>
				Email:<br>
				<input type="text" name="email" size="20" value="<?php echo $email; ?>"><br>
				Subject:<br>
				<input type="subject" name="subject" size="20" value="<?php echo $subject; ?>"><br>
				Message:<br>
				<textarea name="message" rows="7" cols="30"><?php echo $message; ?></textarea><br>
				<input type="submit" name="submit" value="Send">
			</form>
		</div>
<?php
}
include 'template/index.php';
exit();
}
?>

Do something like:

 

$errors = array();

//for each error you have name it $errors[]

$errors[] = "first error";
$errors[] = "second error";
$errors[] = "third error";

foreach($errors AS $error){
echo $error . "<br>\n";
}

I added the

 

$errors = array();

 

part but im still getting the error

Ah, you're calling it inside a function.

 

after you open the function add this:

 

global $errors;

[Northern Flame]

so should it be

 

function pageContent(){

global $errors;

......

}

 

or

 

pageContent();

global $errors;

 

 

[pocobueno1388]

The first way you said

 

function pageContent(){
global $errors;
......
}
