I have a PHP function that displays an error message as part of form validation, I have mixed in some HTML to create a page for it;
function displayMessage($msg)
{
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=EDGE"/>
<meta http-equiv="Content-Type" content="text/html; charset=Windows-1252"/>
<title>Error sending message</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<div style="box-sizing: border-box; width:100%;font-family:arial;font-size:16px;color:#333333;background:#ffe6e3;padding:10px;background:#ffe6e3;border:1px solid #fb8d8d;">
<?php return $msg; ?>
</div>
</body>
</html>
<?php
}
When the code is run everything looks right in the browser, however, looking at the source code it stops right after the message is displayed so the closing div, body, and html tags are not shown.
How do I get them to show, I have tried echo instead of return but that displays the error message but still processes the form.
You are using functions incorrectly, (similar to a require_once). Functions are meant to be called and return a value, not used to include dynamic code in this manner. The reason why it stops after return $msg is because you are telling the function to return a variable called $msg and end further execution of the function block.
I'd suggest using something like this
function displayMessage($msg)
{
$html = <<<EOD
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=EDGE"/>
<meta http-equiv="Content-Type" content="text/html; charset=Windows-1252"/>
<title>Error sending message</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<div style="box-sizing: border-box; width:100%;font-family:arial;font-size:16px;color:#333333;background:#ffe6e3;padding:10px;background:#ffe6e3;border:1px solid #fb8d8d;">
$msg;
</div>
</body>
</html>
EOD;
return $html;
}
echo displayMessage($msg);
return from a function means instantly going back to whoever called it. Means none of the lines below return will be executed.
Change the below:
<?php return $msg; ?>
To:
<?php echo $msg; ?>
The return keyword should be used only inside a function call.
return means "return this value from the function, and stop executing the function". The keyword that you're actually looking for is echo:
function displayMessage($msg)
{
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=EDGE"/>
<meta http-equiv="Content-Type" content="text/html; charset=Windows-1252"/>
<title>Error sending message</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<div style="box-sizing: border-box; width:100%;font-family:arial;font-size:16px;color:#333333;background:#ffe6e3;padding:10px;background:#ffe6e3;border:1px solid #fb8d8d;">
<?php echo $msg; ?>
</div>
</body>
</html>
<?php
}
Instead of use a return, change to echo. return means that you want return something to outside of the function. One way of use a return would be:
function displayMessage($msg)
{
return '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=EDGE"/>
<meta http-equiv="Content-Type" content="text/html; charset=Windows-1252"/>
<title>Error sending message</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<div style="box-sizing: border-box; width:100%;font-family:arial;font-size:16px;color:#333333;background:#ffe6e3;padding:10px;background:#ffe6e3;border:1px solid #fb8d8d;">
'.$msg.'
</div>
</body>
</html>';
}
And when you call the function you just do:
<?php echo displayMessage(); ?>
Or you can change to echo:
function displayMessage($msg)
{
echo '
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=EDGE"/>
<meta http-equiv="Content-Type" content="text/html; charset=Windows-1252"/>
<title>Error sending message</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<div style="box-sizing: border-box; width:100%;font-family:arial;font-size:16px;color:#333333;background:#ffe6e3;padding:10px;background:#ffe6e3;border:1px solid #fb8d8d;">
'.$msg.'
</div>
</body>
</html>'
}
And call the function:
<?php displayMessage(); ?>

So the idea was this, if i use example.php?u=8, UTF-8 will be used.
I thought this would do the trick.
<?php
$u=($_GET["u"]); // 8 is utf8
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<?php if ($u=8): ?>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php else: ?>
<?php endif ?>
<title>just any title</title>
</head>
<body>
</body>
</html>
Obviously I am doing something completely, wrong, since it doesnt even give me the variable.
Where did i go wrong?

change your php code to this -
<!DOCTYPE html PUBLIC "-//W3C//DTD
➝ XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/
➝ DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/

➝ content="text/html;
➝ charset=utf-8"/>
<title>Greetings!</title>
</head>
<body>
<?php // Script 3.7 - hello.php
error_reporting (E_ALL | E_STRICT);
$name = $_GET['name'];
print '<p>Hello, <span style="font-weight:bold;">'.$name.'</span>!</p>';
?>
</body>
</html>
your link to the php page is working fine, your problem is where u define the name variable, you have a typo, instead of $name = $_GET['name']; you put $name - $_GET['name'];, dont worry this happens to the best of us, fix that and it should run smoothly, btw if you are testing your php code on an online server dont, because it is slower than on your pc, unless you are contacting an api, it doesnt work unless its executing online
EDIT :
change your code to this :
<?php // Script 3.7 - hello.php
error_reporting (E_ALL | E_STRICT);
$name = $_GET['name'];
?>
<p>Hello, <span
style=\font-weight:
bold;\"><?php echo $name; ?></span>!</p>
I need to use "header Refresh" (PHP) + "meta refresh" (HTML) together, the PHP refresh is working, but the meta one is ignored, please help me, thanks

I am using a php script that has a file header.php with the normal web page header info. However, when I add the viewport tag it throws an error.
header.php:

echo "

?>
Error returned:

Thanks for any help on this!
You are not escaping double quotes here
<?php
echo "
<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>
<html xmlns='http://www.w3.org/1999/xhtml'>
<head>
<meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\"/>
<meta http-equiv='Content-Type' content='text/html; charset=utf-8' />
<title>".$websiteName."</title>
<link href='".$template."' rel='stylesheet' type='text/css' />
<script src='models/funcs.js' type='text/javascript'>
</script>
</head>";
?>
OR use single quotes
<?php
echo "

<html xmlns='http://www.w3.org/1999/xhtml'>
