is it possible to embed this into html
if (empty($_POST['extras'])) {
$message .="<br /> No extras selected <br />";
} else {
foreach($_POST['extras'] as $extra)
{
$message .="<br />Extras: ".$extra."";
}
}
I would like to place the above php statement at the bottom of this html code.

If it's got php code in it then it's no more HTML.
You have to call it .php or .phtml.
PHP generates, or outputs html.
You can have pure html in .php scripts (outside the <?php ?> tags), but not the other way around (i.e. no php code in regular .html files).
If you want to add some logic (the PHP code) within it, you need to have it parsed by a webserver which will, in turn, generate html.

I think you're needing to create an empty variable $message before you could start appending "extras" to it. Then all you need to do is echo $message.
Yes you can, however that's not a good way to do it. You should go for the Model-View-Controller model. It separates the HTML code from the actual code that does processing. Many PHP Framework does this. (Though personally i find them too clunky and wrote my own)
Also, embedding HTML into PHP is bad, as again, code should be separated from the HTML by as much as possible.
Example of views and controllers (From my framework):
Controller:
class Controllers extends BaseController{
function index($args=array()){
// process data
$this->render('index', array('data1'=>$data));
}
}
View:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>My site</title>
</head>
<body>
<h1><?php echo $page->data1; // echos out $data from the view ?></h1>
</body>
</html>
This is much cleaner than your model of embedding php into the HTML and/or vice versa.
Take a look at frameworks, they are usually pretty helpful, although PHP frameworks are generally very restrictive as to what you can do.
Yes, you can do what you are asking. Make sure the extension is recognizable by the php interpreter (usually .php)
If you need to hack something up quick, this is ok. But for anything else than that, look into using some sort of templating language. This becomes an important point because you want to seperate your logic from your display for the sanity of yourself and other developers that will work on your code in the future.
edit: oh, also very important. Don't use $_POST this way without sanitizing the data. It's ripe for XSS injections.

I had a problem that I was struggling with a couple days ago, and the problem lies in my session id handling while using localhost (xampp local server).
What I now tried to do, is to create two separate pages, the first one randomizes a session id in such a way:
<?php
session_start();
$random_number = rand();
$_SESSION['random_number'] = $random_number;
?>
<!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" xml:lang="en"
lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=utf-8"/>
<link rel="stylesheet" href="style.css" />
<title>Understanding PHP sessions...Page 1</title>
</head>
<body>
<div id="contentarea">
<div id="innercontentarea">
<h2>Understanding PHP sessions...Page 1</h2>
<p>Random number generated
<span style="font-weight:bold;">
<?php echo $_SESSION['random_number']; ?>
</span>
</p>
<p>PHP session id
<span style="text-decoration:underline;">
<?php echo session_id(); ?>
</span>
</p>
Go to next page
</div>
</div>
</body>
</html>
So, this creates a random session number here, and should output the same number on the second page basic_session2, which basically the same, but the difference is in session initialization, which is only:
<?php
session_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

lang="en">
<head>

<title>Understanding PHP sessions...Page 2</title>
</head>
<body>
<div id="contentarea">
<div id="innercontentarea">
<h2>Understanding PHP sessions...Page 2</h2>
<p>My Favorite movie is
<span style="font-weight:bold;">
<?php echo $_SESSION['random_number']; ?>
</span>
</p>
<p>PHP session id
<span style="text-decoration:underline;">
<?php echo session_id(); ?>
</span>
</p>
</div>
</div>
</body>
</html>
But it echoes out a different random number! So, now, I am guessing there is a problem with my session cookie path, as this session number is not holding up.
The system I use is Ubuntu, and the localhost directory for xampp is a standard one. Do you know how to solve that issue, or maybe encountered such a problem?
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
<? $idne2=$_GET['idne']; ?>

header function will not work if there is any html output before header function.
use JS redirect.

it produces output when it is saved as filename.html
but when i try to change it to filename.php
then open the link in the brown using filename.php
it doesnt produce output anymore
NOTE: i removed some of the code too long

You have to remove <?php and ?>. Between these two tags there must be php-code and no html.
Edit: Maybe no errors are reported, because your server is configured to suppress errors.
Put some space after the echo..And use single quote['] insted of double.And change all single quotes from your code to double quote.(")
eg: -
<?php echo '
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body> Bla bla bla
</body>
</html>';
?>
The problem in your code is, you just started the codes with double quote.So the PHP server consider the next double quote is the closing of the echo statement.So there is nothing to print inside the first two double quote.But if you take the page source, you can see
<!DOCTYPE html PUBLIC
This is because you open PHP tag at the beginning of file:
<?php
Close it before your HTML markup:
<?php
// your php code
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
You can not have html in your php tags, if you want to use html you have to end the close your php first so something like this:
<?php
// php code here
?>
html code here
<?php
// php here
?>
If You need to write html inside php code use the echo statement.
ex:
<?php echo"
<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Strict//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'>
<html xmlns='http://www.w3.org/1999/xhtml'>
<head></head>
<body>
//your code here
</body>
</html>";
?>
FUNCTIONS.PHP
<?php
function global_header($page)
{
echo "
<!doctype html>
<html lang='en'>
<head>
<meta charset='utf-8' />
<title>" . $page . "</title>
<meta name='description' content='BTI320 Assignment 2' />
</head>
<body>
";
}
?>
<?php
function global_footer()
{
echo "
</body>
</html>
";
}
?>
When I view my page source in chrome/FF I get the following source:
<!doctype html>
<html lang='en'>
<head>
<meta charset='utf-8' />
<title>Add</title>
<meta name='description' content='BTI320 Assignment 2' />
</head>
<body>
</body>
</html>
It's indented by about 3 tabs. Is there a PHP strip function or something that can align it properly? I don't like my entire pages HTML being messed up.
My expected output is to not be indented.
The reason you are getting indented outputs is that you are echoing them like that...
Simply remove the indentaions from the echo statements to get rid of them
<?php
function global_header($page)
{
echo "
<!doctype html>
<html lang='en'>
<head>
<meta charset='utf-8' />
<title>" . $page . "</title>
<meta name='description' content='BTI320 Assignment 2' />
</head>
<body>";
}
?>
<?php
function global_footer()
{
echo "
</body>
</html>";
}
?>
This makes your php harder to follow fut the output will be as you requested
Consider using a template engine. Direct output of HTML strings is considered bad practice.
If you don't want to use third-party template engines, you can anyway benefit from some simplified templating like this:
page.tpl template file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset='utf-8' />
<title>{{title}}</title>
</head>
<body>
{{body}}
</body>
</html>
PHP:
// Loading HTML code that does not contain any undesired whitespace.
$code = file_get_contents('page.tpl');
// Replacing template variables with their values.
$code = str_replace(
array(
'{{title}}',
'{{body}}'
),
array(
'Example title',
'Page body'
),
$code
);
// Outputting resulting HTML code.
echo $code;
I am on PHP 5.2.17 (and I am no PHP expert). I was hoping the following would display properly:
<?php
$title = "Jérôme";
echo $title."<br>";
?>
But it displays:
Jérôme
How can display my string properly? (The string is static)
Add to your HTML head:
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
Note that you should have a proper HTML doctype because browsers default to non utf8. You can do a simple test, like I did, this works:
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<?php
$title = "Jérôme";
echo $title."<br>";
But the place for the meta tag is in the head tag. The HTML document should look like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>An XHTML 1.0 Strict standard template</title>
<meta http-equiv="content-type"
content="text/html;charset=utf-8" />
</head>
<body>
<?php
$title = "Jérôme";
echo $title."<br>";
?>
</body>
</html>
That is standard.
<meta http-equiv="content-type" charset="utf-8" content="text/html;" />
<?php
$title = "Jérôme";
echo htmlspecialchars($title);
?>
Use php htmlentities function. see below example
$title = "Jérôme";
$title= htmlentities($title);
echo "<BR>Title :".$title."<br>";
