node_delete not working - php

I am trying to delete some CCK nodes in Drupal using a standalone PHP script while logged in as anonymous user
if(empty($total_deals_for_this_pl)){
$node_nid = $single_result['nid'];
global $user;
$original_user = $user;
$user = user_load(1);
print $node_nid."<br>";
node_delete($node_nid);
$user = $original_user;
}
I am able to retrieve all the nid's successfully but the nodes are not getting deleted. I am loading Drupal as follows
chdir('C:\wamp\www\mysite\platform'); //my drupal resides here
require_once './includes/bootstrap.inc';
include_once './includes/common.inc';

Node_delete() has an access check for delete permissions inside it.
Test again with anonymous users given permission to delete nodes.
Also try adding
drupal_bootstrap(DRUPAL_BOOTSTRAP_DATABASE);
If that doesn't work you could try up to the session phase:
drupal_bootstrap(DRUPAL_BOOTSTRAP_SESSION);
and finally the full dealio:
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

Three options:
Generally, I would recommend using VBO for this kind of thing. Its a more robust solution than a custom script. It's pretty easy to set up and once you've used it you'll probably think of a dozen other ways to use it.
Failing that, make your own module and stick your custom script inside a proper hook. Your custom script on its own might not be playing along with what other modules are expecting.
If you still want to have your own separate script I suspect it's the bootstrap code that's failing. Check out drupal_bootstrap for the options available to you.

Use of undefined constant ABSPATH

I am using WP for the first time. I'm just trying to create a very basic script to echo the user's id and am having all sorts of issues.
The code is this and is currently located in wp-content/plugins (i'm not really sure where these things should be):
<?php
require_once ABSPATH . '/wp-includes/pluggable.php';
$user = wp_get_current_user();
echo $user->get_site_id();
I'd had it without the require initially but I was getting a function not defined error for wp_get_current_user. Now I'm getting Warning: Use of undefined constant ABSPATH - assumed 'ABSPATH'...
Is there some sort of predefined set of files that I need to include or some specific directory I need to be putting my scripts so that these variables and functions are in scope? My understanding was that these things are supposed to be global.
Did you try code like that:
add_action('init', 'some_function_name');
function some_function_name() {
$user = wp_get_current_user();
echo $user->get_site_id();
}
The WordPress comes with hooks (actions and filters) to let other developers modify either core parts of the WordPress or code from other plugins / themes.
The code I describe in my answer, it is running your code when the whole WordPress , all the Plugins and the theme are loaded, thus you should have by default the wp_get_current_user() function and you should not need to include manually the pluggable.php.
This seems like is going to solve your problem.
Read more on hooks here: https://developer.wordpress.org/plugins/hooks/.
Side note. Keep in mind that in order to run your custom code you should register a proper WordPress plugin and activate it. If you have made a php file in the plugins folder, and you loaded using PHP functions like require/include the plugin probably will not operate as you expect although the source code it could be perfect. To get more details on how to write your own plugin, you could read here: https://developer.wordpress.org/plugins/

include typoscript with php

Is it possible to include a typoscript file via php?
Normally I would include typoscript with this:
<INCLUDE_TYPOSCRIPT: source="FILE:fileadmin/templates/typoscript/setup/1.ts">
But I want to do this just with php and not typoscript. Is that possible?
My Purpose: I want to dynamically load typoscript in my page
This can be achieved by invoking accordant functions at an early stage, e.g. in calling or delegating it in ext_localconf.php. For example, the bookstrap package is loading TypoScript in PHP like this:
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPageTSConfig(
'<INCLUDE_TYPOSCRIPT: source="FILE:EXT:' . $_EXTKEY
. '/Configuration/PageTS/Mod/Wizards/newContentElement.txt">'
);
Please consider, that TypoScript is cached before the actual front-end rendering starts. This means, that you should not modify TypoScript if you're plugin class or controller logic has been called already.
May be you need to return a value from the php function and use typoscript conditions for choosing the typoscript file.
You might try the following (if I get you right):
$typoscriptFile .= file_get_contents($someFile);
$parser = t3lib_div::makeInstance('t3lib_TSparser');
$parser->parse($typoscriptFile);
$tsArray = $parser->setup;
I really don't know how well that will play with anything related to global typoscript though.
If you wanted a complete correct parse, you might be able to pull something like this off if you populated a fresh t3lib_TStemplate instance from $GLOBALS['TSFE']->tmpl and than ran the code above. Might work, never tried.

Yii: Creating a Demo Site Without Replicating the Code Base

I need to set up a demo site for users to try a web app before signing up. The demo would be based on production code, however, it would require minor code changes: connection to a demo database, automatic creation/login of a new guest account for each user, etc.
The obvious solution is to replicate my code base as a second demo website and edit as necessary. Keeping the demo code in sync with production code is easy enough by adding a branch in subversion. I'm less than thrilled, however, at the prospect of having to do two updates on my server (production and then demo) every time I push code from development to production.
Initially I thought I might be able to replicate the website through a module. It's unclear if this is possible, however.
Is there a mechanic in Yii to execute an altered version of a website (config file and selected controllers)?
Never do before, so just an idea
solution with few files in other dir
create a separate a demo dir and map it on your demo URL
In this dir put this index.php (may be your .htaccess too)
<?php
$yii=_PRODUCTION_PATH_.'/framework/yii.php';
$config_prod=_PRODUCTION_PATH_.'/protected/config/main.php';
$config_demo=dirname(__FILE__).'/demo_main.php';
require_once($yii);
$config = CMap::mergeArray($config_prod,$config_demo);
Yii::createWebApplication($config)->run();
the demo_main.php override the classes (user, db) to manage a better demo experience:
<?php
return array(
'basePath'=>_PRODUCTION_DIR_.DIRECTORY_SEPARATOR.'..',
'components'=>array(
'user' => array(
// here you override the user class with a DEMO only user
'class'=>'DemoUser',
)
),
solution with all files of prduction site in a different dir
Here follows the index.php in root dir
<?php
$yii='../framework/yii.php';
$configMain = include dirname(__FILE__).'/protected/config/main.php';
$configProd = include dirname(__FILE__).'/protected/config/production.php';
$configDemo = include dirname(__FILE__) . '/protected/config/demo.php';
require_once($yii);
// for the demo version
// instead of the comment can be an *if* or any solution to manage 2 configs
//$config = CMap::mergeArray($configMain,$configProd);
$config = CMap::mergeArray($configMain,$configDemo);
Yii::createWebApplication($config)->run();
demo.php is analogue to "demo_main.php" overridig classes and configs for the demo version of the site.
The testdrive demo app is configured for this - after you install, note the separate index-test.php, and protected/config/test.php.
Unlike #IvanButtinoni's suggestion, you'll need to access index-test.php, instead of index.php, so you may need to modify your .htaccess if you're using clean URLs to allow access to index-test.php.
When I do this, I usually write a custom init in the base controller.php:
public function init() {
// use test layout if using test config
if (isset(Yii::app()->params['test'])) {
$this->layout='//layouts/test';
}
parent::init();
}
Obviously, I have a test parameter in my test.php . . .
The only difference in my two layouts is that one sets the background color to be a bright yellow, just so it's very clear you're on a test site.
If I have understood well (according to the comment answers to original post) then There are several ways. Here is a link that I think can help great deal. It helped me set up and may be will help you!
In Yii 2 it will be inherently supported

Context-aware AJAX call in a modular site

Edit: I thought about a possible solution, but I made another question as it is very specific: see AJAX proxy with PHP, is it possible?
A couple of times I've encountered this problem...
I create sites that have a certain degree of modularity. So, it is possible that there are "components" (think of a rough CMS) which carry their own PHP code, CSS, and JavaScript, all dynamically included. Think about a structure like:
{siteroot}/component/datagrid/datagrid.php
{siteroot}/component/datagrid/js/datagrid.js
{siteroot}/component/datagrid/css/datagrid.css
{siteroot}/component/datagrid/ajax/getsomedata.php
Now, the question is: for JavaScript files, and expecially AJAX calls, how do I make them context-aware with the URLs?
For example, if in datagrid.js I want to call siteroot/component/datagrid/ajax/getsomedata.php with AJAX I should write (with JQuery):
$("#ajax").load("siteroot/component/datagrid/ajax/getsomedata.php");
First problem: siteroot changes on different installations. I've managed that by including a general
var codeBase = <? echo json_encode(Config::$siteRoot); ?>
with PHP on every page, from a Config file that can be easily edited for every installation, so I can do with whatever JavaScript something like:
$("#ajax").load(codeBase + "/component/Datagrid/ajax/getsomedata.php");
What do you think of this approach?
Second problem: but I have PHP functions that return to me also the components folder, or the folder of other components. It would be nice to make the whole URL dynamic. This would account also for changes in the structure of the component if I want.
The only solution I've found is to use a .js.php dynamic Javascript. This is very unelegant, and I have to include all the framework in the JavaScript file, like:
<?php
include "../../libs/framework.php"; // get my functions...
$myUrl = Config::$siteRoot . Framework::getComponentAjaxDir("datagrid") . "/getsomedata.php";
?>
$("#ajax").load(<?=json_encode($myUrl)?>);
Another side effect is that I have to know exactly the include the path for framework.php... I don't want this so hard-codedin my ".js.php" file.
Any smart solutions about that?
As nobody answered in a suitable way, I answer to myself to provide a solution I've found out that can be useful.
The key to my solution is simple:
I create an AJAX proxy at a fixed location in my site structure, so I can use codeBase to reference the proxy from JavaScript
I call this proxy with two parameters: plugin and action, which identify a) the plugin folder in which the "real" ajax is and b) the ajax file to use, along with the other params:
$("#...").load( codeBase + "/main/ajax.php?plugin=Datagrid&action=gettable&otherparams"...)
In ajax.php I sanitize the parameters, and use plugin and action to obtain the "real" ajax file:
{serverRoot}/components/{plugin}/ajax/{action}.php
Then i simply include that file in ajax.php
To be honest your problems are realistic options and aren't that bad practice in general quite frankly.
But let's explore this a little further.
What would be the best approach is for you to have 1 main config.php file which you can then specify modules, i.e. your datagrid etc.
You could store all modules in an array variable like so:
$_SITE_PATH = "/var/www/html/";
$_HTTP_PATH = "http://example.com/";
$_MODULES_PATH = $_SITE_PATH."modules/"
$_MODULES = array(
"datagrid"=>$_MODULES_PATH."datagrid/init.php",
"something_else"=>$_MODULES_PATH."something_else/init.php"
);
Each module would have it's own directory with instantiation init.php so that it would load all it required to get going.
This way you could code as you liked and when you needed something (preferably in the header state) do something like this.
global $_MODULES;
require_once($_MODULES["datagrid"]);
Everything will be easily available as and when required without any variable path issues later down the line.

Is it possible to dynamically reload PHP code while script is running?

I'm having a multiplayer server that's using PHPSockets, and thus is written entirely in PHP.
Currently, whenever I'm making any changes to the PHP server-script I have to kill the script and then start it over again. This means that any users online is disconnected (normally not a problem because there aren't so many at the moment).
Now I am rewriting the server-script to use custom PHP classes and sorten things up a little bit (you don't want to know how nasty it looks today). Today I was thinking: "Shouldn't it be possible to make changes to the php source without having to restart the whole script?".
For example, I'm planning on having a main.php file that is including user.php which contains the class MyUser and game.php which contains the class MyGame. Now let's say that I would like to make a change to user.php and "reload" the server so that the changes to user.php goes into effect, without disconnecting any online users?
I tried to find other questions that answered this, the closest I got is this question: Modifying a running script and having it reload without killing it (php) , which however doesn't seem to solve the disconnection of online users.
UPDATE
My own solutions to this were:
At special occations, include the file external.php, which can access a few variables and use them however it'd like. When doing this, I had to make sure that there were no errors in the code as the whole server would crash if I tried accessing a method that did not exist.
Rewrite the whole thing to Java, which gave me the possibility of adding a plugin system using dynamic class reloading. Works like a charm. Bye bye PHP.
Shouldn't it be possible to make changes to the php source without having to restart the whole script?
[...]
I'm planning on having a main.php file that is including user.php
which contains the class MyUser
In your case, you can't. Classes can only be defined once within a running script. You would need to restart the script to have those classes redefined.
I am not too familiar with PHP but I would assume that a process is created to run the script, in doing so it copies the instructions needed to run the program and begins execution on the CPU, during this, if you were to "update" the instructions, you'd need to kill the process ultimate and restart it. Includes are a fancy way of linking your classes and files together but ultimately the processor will have that information separate from where the file of them are stored and it is ultimately different until you restart the process.
I do not know of any system in which you can create code and actively edit it and see the changes while that code is being run. Most active programs require restart to reload new source code.
Runkit will allow you to add, remove, and redefine methods (among other things) at runtime. While you cannot change the defined properties of a class or its existing instances, it would allow you to change the behavior of those objects.
I don't recommend this as a permanent solution, but it might be useful during development. Eventually you'll want to store the game state to files, a database, Memcache, etc.
How about storing your User object into APC cache while your main script loads from the cache and checks every so often for new opcode.
To include a function in the cache, you must include the SuperClosure Class. An example would be:
if (!apc_exists('area')) {
// simple closure
// calculates area given length and width
$area = new SuperClosure(
function($length, $width) {
return $length * $width;
}
);
apc_store('area', $area);
echo 'Added closure to cache.';
} else {
$func = apc_fetch('area');
echo 'Retrieved closure from cache. ';
echo 'The area of a 6x5 polygon is: ' . $func(6,5);
}
See here for a tutorial on APC.
Simple solution use $MyUser instead of MyUser
require MyUserV1.php;
$MyUser = 'MyUserV1';
$oldUser = new $MyUser('your name');
//Some time after
require MyUserV2.php;
$MyUser = 'MyUserV2';
$newUser = new $MyUser('your name');
Every declared class stay in memory but become unused when the last MyUserV1 logout
you can make them inherit from an abstract class MyUser for using is_a
You cannot include again a file with the same class, but you can do so with an array. You can also convert from array to class, if you really need to do so. This only applies to data, though, not to behavior (methods).
I don't know much about these things with the games on PC but you can try to get all the variables from your database for the user and then update the text fields or buttons using those variables
In web is using AJAX (change data without refreshing the page).Isn't one for programming?
