php loading modules query 2

[aa__live]

I'm learning php and the question is probably simple to many of you, what is the loading procedure of this url?

http://www.mysite.co.uk/index.php?module=members&controller=reputation&action=browse

there are many folders named like the above, I'm assuming its MODULE first or is the root index.php file ran first?

Thanks for patience

 

[vacunita]

Yes, very likely in the App folder or config folder. the XML file may also need to have an entry added to it so it can find all the appropriate pieces.

Yes i sussed the xml out and I copied the selling section then renamed the tab, but soon as a added a new file name (like ie: test.phtml) file not found, i will have a look in app folder and config

Ok why this section on tek-tips isn't busy thought I would ask the question, what is bootstrap doing in this function?

    public function bootstrap()
    {
        if (!empty($this->_options['modules'])) {
            $this->_moduleManager = ModuleManager::getInstance()
                    ->setModules($this->_options['modules']);

            $this->setOptions(
                    $this->_moduleManager->getConfig(
                            $this->_moduleManager->getActiveModule()));

            $this->_autoloader->addPaths(
                    $this->_moduleManager->getPaths());
        }
        else {
            throw new \InvalidArgumentException('At least one module needs to be created in order for the application to function.');
        }

        $this->getBootstrap()->bootstrap();

        return $this;
    }

I'm pretty rusty coming back to programming, finished in 2005 but I never know such an enigma trying to follow this code

If I remember is the variable $this used within the object? I get this message after declaring some libraries

Fatal error: Using $this when not in object context - $stmt = $this->_adapter->query($query);

At some point the front page items should be called calling index.php but I'm trying to find where, this is the full code page of cube/application.php

It's not "BootStrap" as in the javascript/CSS/HTML 'framework' usage, it is the 'bootstrapping' usage of being;

"Trying to pull yourself up by your boot straps (laces)" which is why 'booting' a computer is termed as such.

In your case "bootstrap()" is likely to be a method, the OOP term for a function, that 'kicks/boots' the application into an initial state then run() is the method that starts the main process(es)

I see, its very hard to follow, i have my own import code, all i need is the connection to db and execute methods but its ny on impossible to find. Even in the view folders wrapped in html with extension .phtml is the use of $this-> outside its class, there are no includes in any file so i'm baffled how this bloody project works, should i resort in pulling in my own PDo calls? that too me is reinventing the wheel if i already have it hidden somewhere, any particular searches i could use to find a connection?

 

[aa__live]

After this call... where does this go? and if someone clicked a link that didnt run index.php how would it run bootstrap?

ini_set('display_errors', 1);
error_reporting(E_ALL);

define('APPLICATION_PATH', realpath(__DIR__));

set_include_path(APPLICATION_PATH . DIRECTORY_SEPARATOR . 'library');

require_once 'Cube/Application.php';

$application = Cube\Application::init(include 'config/global.config.php');
$application->bootstrap()
        ->run();

 

[ChrisHirst]

where does this go?

That depends entirely on what run() tells it to do.

if someone clicked a link that didnt run index.php

index.php will ALWAYS run if the folder URI is requested, that's the reason for having a 'default document' for a folder so site.tld/folder/index.php does not have to be explicitly specified.

Looking at the above code i pasted "class Application" can you tell me off that?

Could you be a little less vague as to what you are asking????

[aa__live]

could i ask, "this" is used everywhere, is "this"

$this->getBootstrap()->run();

equivalent too

$Application->getBootstrap()->run();

in the above code?

 

[aa__live]

My problem is I have theme files extension .phtml using code within the file and no include classes at the top of the page and the use of the word $this in the file so I have no reference has to what object it is?

Fatal error: Using $this when not in object context

if ($this->userDetails($this->loggedInUser['id'])->getUser()->isVerified() === false) { 
	echo $this->partial('partials/user-verification-message.phtml', null); 
}

the file has no declaration to the object above this

 

[ChrisHirst]

so I have no reference has to what object it is?

Correct.

[aa__live]

In this circumstance, is "view" a class somewhere?

$view->loggedInUser = $this->_user;

 

[vacunita]

Its an object. It may or may not be an object instantiated from a defined class however.

The line is simply setting the loggedInUser Property of the $view object to whatever the current object's _user property is set to.

I thought so, trouble is, I cannot find "loggedInUser" anywhere declared other than like the above, its not a function, it looks like part of an array, how could I search for it to see how its contructed

 

[vacunita]

Probably because its not constructed anywhere else but there where its being set to _user.

Some class somewhere is setting or constructing _user however.

You could attempt to output _user using var_dump() function to see what else may be in there.

echo var_dump($this->_user);

I will add to existing see what i can find, is there anyway of finding the class associated to "$this" at that point? "$this" is used all over this project with no real clue to what object it actually is, is that bad practice?

 

[ChrisHirst]

$this" is used all over this project with no real clue to what object it actually is, is that bad practice?

No, because '$this' is ONLY a valid object reference inside the object it it is referring to. So $this may be used many, many times in the code of an application which accesses or instantiates several classes, but it only ever has scope within the 'present' object, 'past' references, or 'future' instantiations of objects MUST be referenced by name.

How can i follow for example this *.phtml file? there is no instantiation of a class but uses '$this' so how can i know what object this is? you can understand my conversion, when i used c++ years ago, the include to an object was added at the top of the page so you had some idea where to look

<!DOCTYPE html>

<html dir="<?php echo $htmlDir = $this->htmlDir(); ?>" lang="<?php echo $this->htmlLang(); ?>">
<head>
    <?php echo $this->headTitle(); ?>

    <?php
    $this->headMeta()
        ->appendName('viewport', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no')
        ->appendHttpEquiv('X-UA-Compatible', 'IE=edge');
    echo $this->headMeta();
