php 404 isset help

[mrooks1984]

Hello all, i am hoping someone can help me.

 

i have some code i have been working on and i am trying to add a 404 page if it cant find the page, i know it will be some sort of if statment, but with me been pretty much a noob at php i am stuck.

 

heres the code that the page calls.

 

function get_content() {

	//Get page name from browser if none call it home
	$page = (isset($_GET['page'])) ? $_GET['page'] : 'home';

	//Get The Page Content
	$sql = "SELECT * FROM content WHERE page = '$page'";
	$res = mysql_query($sql) or die (mysql_error());
	while($row = mysql_fetch_assoc($res)){

		//Show The Page Content
		echo '<h1>' . $row['title'] . '</h1>';
		echo $row['body'];
	}
}

 

thanks all.

hi,

 

heres an example:

 

$sql = "SELECT * FROM content WHERE page = '$page'";
$res = mysql_query($sql) or die (mysql_error());

if (0 === mysql_num_rows($res))
{
// page not found
// send a header and exit
}

while($row = mysql_fetch_assoc($res)){
