I have one controller which need to output in one view file and $_GET param.
Controller code is:
public function action_register_final() {
//Detect view file
$block_center = View::factory('pages/v_register_final');
$block_center = $this->request->param('user_id');
//Detect block
$this->template->block_center = array($block_center);
}
But this code is output only $_GET param... if i remove $block_center = $this->request->param('user_id'); view is loading good and output. I know i replace $block_center but how I can to output both values.
Thx.
Watch. You overwrite your variable. I think you need this:
public function action_register_final()
{
// Detect view file
$this->template = View::factory('pages/v_register_final');
$this->template->block_center = array($this->request->param('user_id'));
}
Or.
public function action_register_final()
{
// Detect view file
$this->template = View::factory('pages/v_register_final');
$block_center = this->request->param('user_id');
$this->template->block_center = array($block_center);
}
Not tested. This is what you need? Where is your second array? Try merge.

I know that you can use extract() to achieve this however my circumstances are as followed:
I am building a very small basic MVC framework for personal projects and I have this in my controller:
public function index(){
$data = [
'title' => 'Welcome'
];
$this->view('pages/index', $data);
}
As you can see this passes the data array into the view and you can echo it like:
echo $data['title'];
But I want to echo it like echo $title; I know that extract() can do this but that means I have to manually put extract($data); at the top of every page which isnt the end of the world but I was just curious if there was a way it could be done automatically? I have tried to use extract by putting it inside the view function but that did not work. I have also tried to use extract by putting it in the header file that is required_once in index.php (thus making the header file a static header thats always required) but neither has worked so any advice would be great.
Here is the code for the view function as requested:
public function view($view, $data = []){
if(file_exists('../../views/'.$view.'.php')){
require_once '../../views/'.$view.'.php';
} else {
die('View does not exist');
}
}
Simple that is it ,use compact and extract function
index method
public function index(){
$title='Welcome';
$this->view('pages/index', compact('title'));
}
Wiew method
public function view($view, $data = []){
extract($data);
if(file_exists('../../views/'.$view.'.php')){
require_once '../../views/'.$view.'.php';
} else {
die('View does not exist');
}
}
In html
<h1> hello <?php echo $title; ?></h1>
Here is where I went wrong, I put extract in the view method before and it didn't work.
However the advice here was to put it in the view function and I now understand that I put the extract function after require_once '../../views/'.$view.'.php'; I just put extract before that line of code and it is now working!
I've been racking my brains over this one but I'll do my best to describe the problem as best as possible. I have a custom function written within template.php, with a bunch of conditionals. When a condition is true, I would like to assign a value to a variable, and then pass that variable intro a node preprocess function that allows that variables to be rendered on a node template.
The function containing the condition:
function _mytheme_date_repeat_string($vars) {
$exdate_pos = strpos($rrule['WKST'], 'EXDATE:');
if($exdate_pos > 0) {
$vars['testvar'] = 'abc123';
}
}
The preprocess function that I would like to render the variable in for node template use:
function mytheme_preprocess_node(&$vars, $hook) {
$vars['new_variable'] = $testvar;
}
Intended usage in node.tpl.php:
<?php print $new_variable; ?>
I'm not great with PHP, but I know enough about programming to know that variable scope might be an issue here. What would be the best way to implement this? Any guidance is greatly appreciated.
Thanks,
Mark.
If it is not called, your _mytheme_date_repeat_string() function will never be executed. Preprocess functions (ie. any function starting mytheme_preprocess_, are called automatically by Drupal's theme system.
What you need is either move the code of _mytheme_date_repeat_string() in mytheme_preprocess_node() or refactor it and call it.
function _mytheme_date_repeat_string($rrule) {
$exdate_pos = strpos($rrule['WKST'], 'EXDATE:');
if($exdate_pos > 0) {
return 'abc123';
}
else {
return NULL;
}
}
/**
* Prepares variables for node templates.
*/
function mytheme_preprocess_node(&$variables, $hook) {
// Get $rrule from somewhere
$rrule = ... ;
$testvar = _mytheme_date_repeat_string($rrule);
if ($testvar) {
$variables['new_variable'] = $testvar;
}
}
You code does not show where the $rrule calue comes from. I assume you would get it for $variables['node'].
I have created my own little PHP framework for fun, however, I am having trouble passing variables from bootstrap to the views....
if I put an echo,print_r,var_dump my target variable in the bootstrap, the output is displayed in the browser before the tag... yet the target var in bootstrap.php is not available in the view, it is coming up as "" even though at the top of the page it is being output correctly....
Somethings I noticed from similar questions:
- The target variable is not being over written
- The include target path is correct and the file exists
- The file is only being included one time (include_once is only fired once)
Any ideas are greatly appreciated, I am pulling my hair out over here lol...

If you just want to display your site name, I think you can use a constant like that :
define('SITE_NAME', "Jeff's Site");
And then display it in your index.tpl :
<?php echo SITE_NAME; ?>
Or, you can send your variables to the view by extending a little bit your JLR_Core_Views :
class JLR_Core_Views
{
private $data;
public function loadView($templatePath, $data = array())
{
$this->data = $data;
$templatePath = JLR_ROOT . '/webroot/' . $templateName . '.tpl';
if(file_exists($templatePath)) {
// Yes, I know about the vuln here, this is just an example;
ob_start();
include_once $templatePath;
return ob_get_clean();
}
}
function __get($name)
{
return (isset($this->data[$name]))
? $this->data[$name]
: null;
}
}
Then, you can call your template like that :
$view = new JLR_Core_Views();
$view->loadView("index", array("sitename" => "Jeff's Site"));
And here is your index.tpl :
<?php echo $this->siteName; ?>
Below is another example of what you can do.
First, you create this class in order to store all the variables you want :
<?php
class JLR_Repository {
private static $data = array();
public function set($name, $value) {
self::$data[$name] = $value;
}
public function get($name) {
return (isset(self::$data[$name]))
? self::$data[$name]
: null;
}
}
?>
Then, when you want to store something in it :
JLR_Repository::set("sitename", "Jeff's Site");
And in your index.tpl :
<?php echo JLR_Repository::get("sitename"); ?>
try using the 'global' keyword - http://php.net/manual/en/language.variables.scope.php
I am using Kohana 3.2 and I am having problems calling the ouput of a controller in another controller.
What I want...
In some pages I have got a menu, and in others I don't. I want to use make use of the flexability of the HMVC request system. In the controller of a page I want to call another controller which is responsible for the creation of the menu.
What I have a the moment:
file menu.php:
<?php defined('SYSPATH') or die('No direct script access.');
class Controller_Menu extends Controller
{
private $_model = null;
public function __construct(Request $request, Response $response)
{
parent::__construct($request, $response);
$this->_model = Model::factory('menu');
}
public function action_getMenu()
{
$content = array();
$content['menuItems'] = $this->_model->getMenuItems();
// Render and output.
$this->request->response = View::factory('blocks/menu', $content);
//echo '<pre>'; print_r($this->request->response->render()); echo '</pre>'; die();
}
}
somepage.php
public function action_index()
{
$this->template->title = 'someTitle';;
$contentData['pageTitle'] = 'someTitle';
$contentData['contentData'] = 'someData';
#include the menu
$menuBlock = Request::factory('menu/getMenu')->execute();
$menuData = array('menu' => $menuBlock);
$this->template->menu = View::factory('pages/menu')->set('menu',$menuData);
$this->template->content = View::factory('pages/somePage', $contentData);
$view = $this->response->body($this->template);
$this->response->body($view);
}
If I uncomment the following line in menu.php, I see the menu rendered:
//echo '<pre>'; print_r($this->request->response->render()); echo '</pre>'; die();
So I guess that part is alright. The problem is in the following line in somepage.php:
$menuBlock = Request::factory('menu/getMenu')->execute();
This gives me back a response object. Whatever I do, I do not get the output in $this->template->menu.
$this->template->menu = View::factory('pages/menu')->set('menu',$menuData);
What must I do to have $this->template->menu contain the view, so I can use it correctly?
I hope this all makes sense. This is the way I would like to do it, but maybe I am completely on the wrong track.
I would do it this way:
class Controller_Menu extends Controller
{
public function action_build()
{
// Load the menu view.
$view = View::factory('navigation/menu');
// Return view as response-
$this->response->body($view->render());
}
}
In your controller get the menu as follows:
// Make request and get response body.
$menu = Request::factory('menu/build')->execute()->body();
// e.g. assign menu to template sidebar.
$this->template->sidebar = Request:.factory('menu/build')->execute()->body();
I would not use the __construct method in your controllers. Use before() instead, this is sufficient for most of the problems (for example auth):
public function before()
{
// Call aprent before, must be done here.
parent::before();
// e.g. heck whether user is logged in.
if ( !Auth::instance()->logged_in() )
{
//Redirect if not logged in or something like this.
}
}
I found the answer to my problem in less than an hour after asking.
I just forgot to put it here.
In somePage.php change :
$menuBlock = Request::factory('menu/getMenu')->execute();
$menuData = array('menu' => $menuBlock);
$this->template->menu = View::factory('pages/menu')->set('menu',$menuData);
To:
$this->template->menu = Request::factory('menu/getMenuBlock')->execute()->body();
And in menu.php change:
$this->request->response = View::factory('blocks/menu', $content);
To:
$request = View::factory('blocks/menu', $content);
$this->response->body($request);
I hope this will help someone else.
So I'm setting up a system that has a lot of emails, and variable replacement within it, so I'm writing a class to manage some variable replacement for templates stored in the database.
Here's a brief example:
// template is stored in db, so that's how this would get loaded in
$template = "Hello, %customer_name%, thank you for contacting %website_name%";
// The array of replacements is built manually and passed to the class
// with actual values being called from db
$replacements = array('%customer_name%'=>'Bob', '%website_name%'=>'Acme');
$rendered = str_replace(array_keys($replacements), $replacements, $template);
Now, that works well and good for single var replacements, basic stuff. However, there are some places where there should be a for loop, and I'm lost how to implement it.
The idea is there'd be a template like this:
"hello, %customer_name%, thank you for
requesting information on {products}"
Where, {products} would be an array passed to the template, which the is looped over for products requested, with a format like:
Our product %product_name% has a cost
of %product_price%. Learn more at
%product_url%.
So an example rendered version of this would be:
"hello, bob, thank you for requesting
information on:
Our product WidgetA has a cost of $1.
Learn more at example/A
Our product WidgetB has a cost of $2.
Learn more at example/B
Our product WidgetC has a cost of $3.
Learn more at example/C.
What's the best way to accomplish this?
Well, I really dont see the point in a template engine that uses repalcements/regex
PHP Is already a template engine, when you write <?php echo $var?> its just like doing <{$var}> or {$var}
Think of it this way, PHP Already translates <?php echo '<b>hello</b>'?> into <b>hello</b> by its engine, so why make it do everything 2 times over.
The way i would implement a template engine is like so
Firstly create a template class
class Template
{
var $vars = array();
function __set($key,$val)
{
$this->vars[$key] = $val;
}
function __get($key)
{
return isset($this->vars[$key]) ? $this->vars[$key] : false;
}
function output($tpl = false)
{
if($tpl === false)
{
die('No template file selected in Template::output(...)');
}
if(!file_exists(($dir = 'templates/' . $tpl . '.php')))
{
die(sprintf('Tpl file does not exists (%s)',$dir));
}
new TemplateLoader($dir,$this->vars);
return true;
}
}
This is what you use in your login such as index.php, you will set data just like an stdClass just google it if your unsure. and when you run the output command it sends the data and tpl to the next class below.
And then create a standalone class to compile the tpl file within.
class TemplateLoader
{
private $vars = array();
private $_vars = array(); //hold vars set within the tpl file
function __construct($file,$variables)
{
$this->vars = $variables;
//Start the capture;
ob_start();
include $file;
$contents = ob_get_contents();
ob_end_clean(); //Clean it
//Return here if you wish
echo $contents;
}
function __get($key)
{
return isset($this->vars[$key]) ? $this->vars[$key] : (isset($this->_vars[$key]) ? $this->_vars[$key] : false) : false;
}
function __set($key,$val)
{
$this->_vars[$key] = $val;
return true;
}
function bold($key)
{
return '<strong>' . $this->$key . '</string>';
}
}
The reason we keep this seperate is so it has its own space to run in, you just load your tpl file as an include in your constructor so it only can be loaded once, then when the file is included it has access to all the data and methods within TemplateLoader.
Index.php
<?php
require_once 'includes/Template.php';
require_once 'includes/TemplateLoader.php';
$Template = new Template();
$Template->foo = 'somestring';
$Template->bar = array('some' => 'array');
$Template->zed = new stdClass(); // Showing Objects
$Template->output('index'); // loads templates/index.php
?>
Now here we dont really want to mix html with this page because by seperating the php and the view / templates you making sure all your php has completed because when you send html or use html it stops certain aspects of your script from running.
templates/index.php
header
<h1><?php $this->foo;?></h1>
<ul>
<?php foreach($this->bar as $this->_foo):?>
<li><?php echo $this->_foo; ?></li>
<?php endforeach; ?>
</ul>
<p>Testing Objects</p>
<?php $this->sidebar = $this->foo->show_sidebar ? $this->foo->show_sidebar : false;?>
<?php if($this->sidebar):?>
Showing my sidebar.
<?php endif;?>
footer
Now here we can see that were mixing html with php but this is ok because in ehre you should only use basic stuff such as Foreach,For etc. and Variables.
NOTE: IN the TemplateLoader Class you can add a function like..
function bold($key)
{
return '<strong>' . $this->$key . '</string>';
}
This will allow you to increase your actions in your templates so bold,italic,atuoloop,css_secure,stripslashs..
You still have all the normal tools such as stripslashes/htmlentites etc.
Heres a small example of the bold.
$this->bold('foo'); //Returns <strong>somestring</string>
You can add lots of tools into the TempalteLoader class such as inc() to load other tpl files, you can develop a helper system so you can go $this->helpers->jquery->googleSource
If you have any more questions feel free to ask me.

An example of storing in your database.
<?php
if(false != ($data = mysql_query('SELECT * FROM tpl_catch where item_name = \'index\' AND item_save_time > '.time() - 3600 .' LIMIT 1 ORDER BY item_save_time DESC')))
{
if(myslq_num_rows($data) > 0)
{
$row = mysql_fetch_assc($data);
die($row[0]['item_content']);
}else
{
//Compile it with the sample code in first section (index.php)
//Followed by inserting it into the database
then print out the content.
}
}
?>
If you wish to store your tpl files including PHP then that's not a problem, within Template where you passing in the tpl file name just search db instead of the filesystem
$products = array('...');
function parse_products($matches)
{
global $products;
$str = '';
foreach($products as $product) {
$str .= str_replace('%product_name%', $product, $matches[1]); // $matches[1] is whatever is between {products} and {/products}
}
return $str;
}
$str = preg_replace_callback('#\{products}(.*)\{/products}#s', 'parse_products', $str);
The idea is to find string between {products} and {products}, pass it to some function, do whatever you need to do with it, iterating over $products array.
Whatever the function returns replaces whole "{products}[anything here]{/products}".
The input string would look like that:
Requested products: {products}%product_name%{/products}
