Just a quick question about the actuall template,
(im going to use an example here)

say this is my template

<html>
<head>
<title>$title</title>
</head>
<body>
$content<br>
Todays Date: $date
</body>
</html>

now that would work, but what about this.

<html>
<head>
<title>$title</title>
</head>
<body>
$content<br>
Todays Date:
<?php
echo gmdate("d-m-Y");
?>
</body>
</html>

Would that work/is their any way to make it run any php inside the template?? I know this defeats the point of a template (seperating the php from the html) but it saves me declairing the date on every page

Thanks

if you used the eval() function then yes, it would.

PHP templates for web pages

I developed my own template-based PHP/MySQL default web site. Anyone is welcome to use it if they like. Be sure to read all the comments so you can follow my logic.

I use three files: "page.inc", "baseCalendar.inc" and "template.php".

I cannot attach the files since they are not valid file types for attachment, so I enclose them in their entirety in the main body of this post.

Here is page.inc:

<?php
// page.inc
// to create a new page, use template.php

class Page {

// default properties for all class members
var $title = "PHP Page";
var $host = "phpHost";
var $user = "phpUser";
var $pwd = "phpPwd";
var $db = "phpDb";
var $MYSQL_ERRNO = '';
var $MYSQL_ERROR = '';

// constructor function (to create a Page object)
function Page($newTitle=false, $newHost=false, $newUser=false, $newPwd=false, $newDb=false) {
$this->title = ($newTitle) ? $newTitle : $this->title;
$this->host = ($newHost) ? $newHost : $this->host;
$this->user = ($newUser) ? $newUser : $this->user;
$this->pwd = ($newPwd) ? $newPwd : $this->pwd;
$this->db = ($newDb) ? $newDb : $this->db;
}

// default methods
function displayTitle() {echo("<title>" .$this->title. "</title>");}

function displayHead() {
?>

return false;

$this->MYSQL_ERROR = mysql_error();

return

Not working with me!

Here is the code:

PHP Code:


		
			
<?

//Conect to the database

include("db.php"); 

dbConnect("test");



function gettemplate($templatename) 

{ 

global $templatecache; 



#check if template has already been loaded 

if ($templatecache[$templatename]!="") { 



#return cached version 

$template = $templatecache[$templatename]; 



} else { 



#retrieve from database 

$query = mysql_query("SELECT content FROM templates WHERE name='$templatename'"); 



if (mysql_num_rows($queryid)!=0) { 



#get the db field 

$template = mysql_result($query,"content"); 



#replace \" with \\" ... this will be needed later in the script 

$template = str_replace("\"","\\\"",$template); 



#cache the contents 

$templatecache[$name] = $template; 



} else { 

$template=""; 

} 

} 

return $template; 

} 



#set the page title and query 

$pagetitle = "Search Results"; 

$searchquery = "Dummy search"; 



#get the database information 

$query = mysql_query("SELECT title,hits FROM items ORDER BY hits DESC LIMIT 10") 



#loop through the results 

while ($data=mysql_fetch_array($query)) { 



#load the template for this instance, appending the data onto $resultbits 

eval("\$resultbits .= \"".gettemplate("ResultsBit")."\";"); 



} 



#now return the whole template 

eval("echo \"".gettemplate("ResultsPage")."\";"); 

?>

It gives me:

Parse error: parse error in /home/telefon/public_html/admin/test.php on line 47

I have both tables (items & templates) setup as said in the article

oops!

How didn't I notice it!
Any way this is how it is in the article, I also noticed anther error in the article, in page 3

Code:

CREATE TABLE items ( 
id int unsigned NOT NULL AUTO_INCREMENT PRIMARY KEY, 
title varchar(30) NOT NULL, 
hits int NOT NULL DEFAULT '',   
);

There is an extra ",".

Now after I added the missing ";" I'm getting anther error:
-START-

Warning: Supplied argument is not a valid MySQL result resource in /home/public_html/test.php on line 21

Warning: Supplied argument is not a valid MySQL result resource in /home/public_html/test.php on line 21

Warning: Supplied argument is not a valid MySQL result resource in /home/public_html/test.php on line 21

Warning: Supplied argument is not a valid MySQL result resource in /home/public_html/test.php on line 21

-END-

It would be nice if the author of this article check it and fix all the error.

Thanx alot

Any chance of getting the support material for this article posted? I am kind of lost, but I would probably be okay if I had the files in front of me to examine.

Thanks

eval() and functions

i was hoping someone would help me out with this...

i used the article's template design in my pages, and it's working quite well. however, i wanted to include a poll within the template HTML, but the poll code is grabbed as...

display_poll(n), where n is the poll id

when i place $poll in the template and use

$poll = display_poll(n);

and then the eval statement to parse $poll, "display_poll(n);" just comes up as plain text instead of the actual poll HTML. any help on this would be greatly appreciated!

Hi everyone. I've just paid another visit to devArticles and noticed all your comments. The two syntax errors you have pointed out have been corrected on the original article at URL There is also a support file available here.

I'd forgotten that this article had already been published here, so I'll have to send an email of to Mitchell.

m0h: The error 'Warning: Supplied argument is not a valid MySQL result resource' means that for some reason an error has occured on the MySQL statement. I suggest you get the actual error message by doing

echo mysql_error();

and see what's gone wrong.

I hope this helps you all

Cheers,

James

I get a syntax error on line 13 when I try to execute this script (came from the article). It is labeled with "(13)".

db.php has the connection details for MySQL. It also selects the database:

PHP Code:


		
			
<? // dummy.php



require_once("db.php");



#set the page title and query

$pagetitle = "Search Results";

$searchquery = "Dummy search";



#get the database information

$query = mysql_query("SELECT title,hits FROM items ORDER BY hits DESC LIMIT 10")



#loop through the results (line 13 follows)

while ($data=mysql_fetch_array($query)) {



#load the template for this instance, appending the data onto $resultbits

eval("\$resultbits .= \"".gettemplate("ResultsBit")."\";");



}



#now return the whole template

eval("echo \"".gettemplate("ResultsPage")."\";");



?>
