So, I have a template engine I made and I want to replace {pageBody} with contents from a PHP file, when I do it using the template engine it does not execute the PHP, rather it displays it in view source option.
TEMPLATE.PHP
<?php
class TemplateLibrary {
public $output;
public $file;
public $values = array();
public function __construct($file) {
$this->file = $file;
$this->file .= '.tpl';
$this->output = file_get_contents('templates/'.$this->file);
}
public function replace($key, $value)
{
$this->values[$key] = $value;
}
public function output() {
foreach($this->values as $key => $value)
{
$ttr = "{$key}";
$this->output = str_replace($ttr, $value, $this->output);
}
return $this->output;
}
}
index.tpl

HTML replace works fine, but PHP does not. Any ideas?
You are rather scattered with your files and the list is incomplete. I've listed all the files you've provided so far below.
#Jonathon above is correct, that you will need to use output buffering to capture the output of the PHP file and include() the file (so it gets executed) instead of using file_get_contents() (which does not execute the file).
[edit] I re-created all these files in my local environment and confirmed that #Jonathon's suggestion worked perfectly. I've updated dev/replacements.php to include the suggested code.
Additionally, I added two more functions to your TemplateLibrary class : replaceFile($key, $filename) that does the file_get_contents($filename) so that you don't have to repeat it so often, and replacePhp($key, $filename) that performs an include() while capturing the output, so you can encapsulate the complexities of including a PHP file.
Good Luck!

[edit] added loaders/pageBody.php from OP's comment.
[edit] Updated dev/replacements.php to capture output buffer and use include on .php
You're using file_get_contents in your pastebin code but you should be using your template processor or PHP's include() instead. If you do $template->replace('{page_header}', $pageHeader), $pageHeader is just the source of the tpl and your template processor does not know that so it will just replace the tag with that source. Fix:
$pageHeader = new TemplateLibrary('header');
// ...
$template->replace('{page_header}', $pageHeader->output());
For the PHP files, you should call include() on the file, wrapped in output buffering, so you can pass the output of the PHP execution as the template variable, instead of the PHP source itself:
ob_start();
include('loaders/pageBody.php');
$pageBody = ob_get_clean();
/// ...
$template->replace('{page_body}', $pageBody);

I am currently trying to create a small template engine for a project that I am working on, and I am using a system where I am replacing {$tag} with a preset tag. So say I put {username} in my template file, it will return a string which is the username. Now I want to go beyond just a simple string replacing a string. So using the same code I put
$tpl->replace('getID', '<?php echo "test"; ?>);
And it didn't work, so when I went to inspect element, I saw that it returned <!--? echo "test"; ?-->...
So now I am just trying to figure out why it returned commented code.
Here is my class file:
class template {
private $tags = [];
private $template;
public function getFile($file) {
if (file_exists($file)) {
$file = file_get_contents($file);
return $file;
} else {
return false;
}
}
public function __construct($templateFile) {
$this->template = $this->getFile($templateFile);
if (!$this->template) {
return "Error! Can't load the template file $templateFile";
}
}
public function set($tag, $value) {
$this->tags[$tag] = $value;
}
private function replaceTags() {
foreach ($this->tags as $tag => $value) {
$this->template = str_replace('{'.$tag.'}', $value, $this->template);
}
return true;
}
public function render() {
$this->replaceTags();
print($this->template);
}
}
And My index file is:
require_once 'system/class.template.php';
$tpl = new template('templates/default/main.php');
$tpl->set('username', 'Alexander');
$tpl->set('location', 'Toronto');
$tpl->set('day', 'Today');
$tpl->set('getID', '<?php echo "test"; ?>');
$tpl->render();
And my template file is:
<!DOCTYPE html>
<html>
<head></head>
<body>
{getID}
<div>
<span>User Name: {username}</span>
<span>Location: {location}</span>
<span>Day: {day}</span>
</div>
</body>
</html>
You're redeclaring PHP in a php file when there is no need to. i.e. you're trying to print <?php which is why it's messing up.
So, you can replace this:
$tpl->set('getID', '<?php echo "test"; ?>');
with this
$tpl->set('getID', 'test');
But, you obviously already know that, you're just trying to go further, the way to do this is by using php inside the set. So, as an idea, you could try this:
$tpl->set('getID', testfunction());
(You're calling testfunction here to define the 'getID' here btw)
So, now you want to write a little function to do something fancy, for the sake of this example:
function testfunction(){
$a = 'hello';
$b = 'world';
$c = $a . ' ' . $b;
return $c;
}
The above should then return hello world in place of {getID}
In reference to your comments - if you want to go one step further and start being more advanced with the return results, you can do the following:
function testfunction(){
$content = "";
foreach ($a as $b){
ob_start();
?>
<span><?php echo $b->something; ?></span>
Some link
<div>Some other html</div>
<?php
$content += ob_get_clean();
}
return $content
}
I just go to the point.
Nvm need to add more text to much code..
Trying to load a Template with php inside it but php prints in html instead.
Init.php
class Init {
public static $ROOT = '';
public static $TEMPLATE = '';
public static $SERVICE = '';
public static function start() {
// Init Paths
Init::$ROOT = str_replace("\\", "/", __DIR__);
Init::$TEMPLATE = Init::$ROOT . "/Template/";
Init::$SERVICE = Init::$ROOT . "/Service/";
// Init Template.php class
require_once(Init::$SERVICE . "Template.php");
// Load template Top.php
$top = new Template(Init::$TEMPLATE . "Layout/Top.php");
echo $top->load(); // Show Top.php
}
}
Top.php
<!DOCTYPE html>
<html>
<?
// Load template Head.php
$head = new Template(Init::$TEMPLATE . "Layout/Head.php");
$head->set("TITLE", "Dashboard"); //Set [#TITLE] to Dashboard
$head->load(); // Show Head.php
?>
</html>

public function __construct($file) {

}
public function set($key, $value) {
$this->values[$key] = $value;
}
// This code works but it will not load php inside
public function load() {
if (!file_exists($this->file)) return "Error loading template file ($this->file).";
ob_start();
include_once($this->file);
$data = ob_get_clean();
foreach ($this->values as $key => $value) {
echo str_replace("[#$key]", $value, $data);
}
if(count($this->values) == 0) echo $data;
}
}
?>
Ive played with allot of functions to make it but it does not work...
It just prints the php in html.
Tried with
ob_start();
include_once(FILE);
$data = ob_get_clean();
Don't use short tags like <? or <?=, use <?php instead. You probably have your short_open_tag set to false in php.ini. If you are using PHP 7 then you should know short tags were removed completely and wont work anymore.
In head.php use the full tag. Change
to
<?php echo "hello"; ?>
I'm new to the Kohana Framework. I have a problem - How can I pass the variable $title from Layout.php to Head.php?
In controller:
<?php defined('SYSPATH') or die('No direct script access.');
class Controller_Admin_Quanly extends Controller_Template {
public $template='admin/layout';
function _showWithTemplate($subview,$title)
{
$admin_path = 'admin/';
$this->template->head = View::Factory(''.$admin_path.'head');
$this->template->subview = View::Factory(''.$admin_path.''.$subview.'');
$this->template->title = $title;
}
public function action_index()
{
$this->_showWithTemplate('subview/home','Trang quản trị hệ thống');
}
}
In view Layout.php:
<!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>
<?php echo $head?>
</head>
<body>
</body>
</html>
In view Head.php:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title><?=$title?></title>
<base href="<?=URL::base()?>">
<link rel="stylesheet" type="text/css" href="style.css" />
<script type="text/javascript" src="javascript/jquery.min.js"></script>
<script type="text/javascript" src="javascript/ddaccordion.js"></script>
You could do something like this:
$admin_path = 'admin/';
$this->template->head = View::Factory(''.$admin_path.'head');
$this->template->head->title = $title;
$this->template->subview = View::Factory(''.$admin_path.''.$subview.'');
$this->template->title = $title;
Note the $this->template->head->title = $title; you need to pass it along manually to the head view.
You can use set() or bind(). See example:
$view = View::factory('user/roadtrip')
->set('places', array('Rome', 'Paris', 'London', 'New York', 'Tokyo'));
->bind('user', $this->user);
Ref: http://kohanaframework.org/3.3/guide/kohana/mvc/views
What you are looking for is set_global
http://docs.kohanaphp.com/core/view#set_global
It will allow you to set a variable for all your views to be able to use. You won't be passing it per say but it will still do what you want.
Example fix
function _showWithTemplate($subview,$title)
{
$admin_path = 'admin/';
$this->template->head = View::Factory(''.$admin_path.'head');
$this->template->subview = View::Factory(''.$admin_path.''.$subview.'');
$this->template->set_global('title', $title);
}
I'm using php class to write data to CSV. Link to class: http://www.jongales.com/blog/2009/09/24/php-class-to-write-csv-files/
Class code:
<?php
/**
* Simple class to properly output CSV data to clients. PHP 5 has a built
* in method to do the same for writing to files (fputcsv()), but many times
* going right to the client is beneficial.
*
* #author Jon Gales
*/
class CSV_Writer {
public $data = array();
public $deliminator;
/**
* Loads data and optionally a deliminator. Data is assumed to be an array
* of associative arrays.
*
* #param array $data
* #param string $deliminator
*/
function __construct($data, $deliminator = ",")
{
if (!is_array($data))
{
throw new Exception('CSV_Writer only accepts data as arrays');
}
$this->data = $data;
$this->deliminator = $deliminator;
}
private function wrap_with_quotes($data)
{
$data = preg_replace('/"(.+)"/', '""$1""', $data);
return sprintf('"%s"', $data);
}
/**
* Echos the escaped CSV file with chosen delimeter
*
* #return void
*/
public function output()
{
foreach ($this->data as $row)
{
$quoted_data = array_map(array('CSV_Writer', 'wrap_with_quotes'), $row);
echo sprintf("%s\n", implode($this->deliminator, $quoted_data));
}
}
/**
* Sets proper Content-Type header and attachment for the CSV outpu
*
* #param string $name
* #return void
*/
public function headers($name)
{
header('Content-Type: application/csv');
header("Content-disposition: attachment; filename={$name}.csv");
}
}
?>
and php code:
if($_GET['action']=="csv") {
$data = array(array("one","two","three"), array(4,5,6));
$csv = new CSV_Writer($data);
$csv->headers('test');
$csv->output();
}
The problem is the resulting file. I have a CSV file instead of the array is only the HTML content page. Why is this happening?
The content of the CSV file:
<!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">

Thx for help.
You have two issues:
You're reinventing the wheel, as PHP already has fputcsv. Don't do that!
From what I can see, you didn't stop executing the script, so PHP is going to go ahead and render the rest of the HTML document. I can't tell exactly why you're not seeing the HTML preceded by CSV info, but maybe the output cache is being flushed somehow. The fix for this is to add an exit(); line at the end of that block:
if($_GET['action']=="csv") {
$data = array(array("one","two","three"), array(4,5,6));
$csv = new CSV_Writer($data);
$csv->headers('test');
$csv->output();
exit();
}
Hi I created two file to switch my forum (Language Chinese and English)

bar();
} // foo()
function bar() {
global $_COOKIES;

There are some files including include template('logon');,include template('regist'); etc, I write some code to get the Cookie value and control the flow to load different template files.
$lang = $_COOKIE["ForumLangCookie"];
// for Debug
// echo '$lang is '.$lang;
// echo '<br/>';
if ($lang == "cn"){
include template('logon');
}
else if ($lang == "en"){
include en_template('logon');
}
But sometime the SetCookie() not working. Do I need add Sleep(someSeconds); for my code?
Cookies can be accessed with $_COOKIE,not $_COOKIES.
EDIT:Sorry for misunderstanding. I suggest you to change the variable $_COOKIES as another common one so people can understand your question correctly.
PHP array name is $_COOKIE, not $_COOKIES
