Templates in a folder
We shall now take a quick look at an equivilant function for reading the template
from a directory.
function gettemplate($templatename) {
global $templatecache;
#check if template has already been loaded
if ($templatecache[$templatename]!="") {
#return cached version
$template = $templatecache[$templatename];
} else {
#retrieve from file
$handle = fopen("./templates/".$name,"r");
$template = fread($handle,filesize("./templates/".$name);
#close the file
fclose($handle);
$template = str_replace("\"","\\\"",$template);
#cache the contents
$templatecache[$name] = $template;
}
return $template;
}
This function does exactly the same as the last, but instead loads the template
from a /templates/ directory (with no file extension).
Now we have our function for reading the template, we can get about using one.
First, however, insert the following 2 templates into the database table, or
into 2 files, depending on the method you wish to use:
Template Name: ResultsPage
<html>
<head>
<title>$pagetitle</title>
</head>
<body>
<h1>$pagetitle</h1>
<p>Below are the results of the search for '$searchquery'</p>
<table border="0">
<tr>
<td><b>Title</b></td>
<td><b>Hits</b></td>
</tr>
$resultbits
</table>
</body>
</html>
Template Name: ResultsBit
<tr>
<td><b><a href="view.php?id=$data[id]">$data[title]</a></td>
<td><b>$data[hits]</b></td>
</tr>
