Developed a social network for MODx Revolution

MODx is developing rapidly, and I decided to try to make a social network on this wonderful engine. After all, it has long been have the ability work with users (registration, authorization, etc.), a built-in mechanism user messages he working with images and a lot more.

Let's start with the users, will give them the opportunity to write articles, for example, or to add your event.

user Registration


To sign up, we'll use the snippet Login.

the 
[[!Register? &postHooks=`addUser` &usergroups=`Users` &submittedResourceId=`9` &activationResourceId=`11` &activationEmailSubject=`Confirm registration` &validate=`email:email:required`]]

About the snippet written already a lot to show you what makes our hook addUser:

Snippet addUser
Snippet addUser

the 
<?php
$output = "";
$parent = 2;
$template = 3;

// Create the resource to the user (his personal page)

if ($id = $modx- > runSnippet('addresource method', array(
'pagetitle' => $hook->getValue('username'),
'parent' => $parent,
'template' = > $template,
'isfolder' = > 1,
'published' => 1,
'hidemenu' => 1
))) {

// Writable id of the page user in the box website
// (although you can use User Extended)

$userId = $hook->getValue('register.user')- > get('id');
$user = $modx- > getObject('modUserProfile', array('id' => $userId));
$user->set('website',$id);
$user->save();

// And for the resource to create a TV-parameter, where you specify the user id

$modx- > runSnippet('tv', array('id' => $id, 'tv' => 1, 'value' => $userId)); 

$modx- > cacheManager- > refresh();

$output = $id;

} else {

print '<h1>Can not to create the new user</h1><p>Please,  tell  us about this</p><h2>Contacts</h2><p>email: <a href="mailto:admin@site.ru">admin@site.ru</a></p>';
die();

}

return $output;


addresource method Snippet
Snippet addresource method

the 
<?php
//  Snippet  to get data from form POST method
if (!$pagetitle) $pagetitle = $_POST['title'];
if (!$longtitle) $longtitle = $_POST['longtitle'];
if (!$content) $content = $_POST['content'];
if (!$introtext) $introtext = $_POST['introtext'];
if (!$description) $description = $_POST['description'];
if (!$parent) $parent = $_POST['parent'];
if (!$isfolder) $isfolder = $_POST['isfolder'];
if (!$hidemenu) $hidemenu = $_POST['hidemenu'];
if (!$template) $template = $_POST['template'];
if (!$menutitle) $menutitle = $_POST['menutitle'];
if (!$published) $published = $_POST['published'];
if (!$publishedon) $publishedon = date('Y-m-d H:i:s');

// If some values are not specified,
// they will be installed by default
if (!$parent) $parent = 1;
if (!$template) $template = 1;

// Set the prefix for the alias
switch ($template) {
case 1: $prefix = "art"; break; // Article
case 2: $prefix = "id"; break; // User
case 3: $prefix = "id"; break; // User
case 4: $prefix = "event"; break; // Event
case 5: $prefix = "animal"; break; // pet
default: $prefix = "id"; break;
}

// Create the resource
$newResource = $modx- > newObject('modResource');

// Fill in the desired values
$newResource- > set('pagetitle',$pagetitle);
$newResource- > set('longtitle',$longtitle);
$newResource- > set('description',$description);
$newResource- > set('introtext',$introtext);
$newResource- > set('content',$content);
$newResource- > set('menutitle',$menutitle);
$newResource- > set('template',$template);
$newResource- > set('isfolder',$isfolder);
$newResource- > set('hidemenu',$hidemenu);
$newResource- > set('parent',$parent);
$newResource- > set('published',$published);
$newResource- > set('alias',$parent.date('YmdHis'));
if ($published) $newResource- > set('publishedon',$publishedon);


// Save the resource
if ($newResource- > save()) {
$id = $newResource- > get('id');
$newResource- > set('alias',$prefix.$id);
$newResource- > save();
// Clear cache so the changes were immediately visible
$modx- > cacheManager- > refresh();
return $id;
} 

return false;


Snippet tv
Snippet tv

the 
<?php
if ($input) {
// Either display the value of TV by id document
$q = $modx- > newQuery('modTemplateVarResource');
$q- > select(array('value',
'tmplvarid',
'contentid'))- > where(array('tmplvarid'= > $options,
'contentid'=>$input)); 
$r = $modx- > getObject('modTemplateVarResource', $q);

return $r->value;

} else {
// either  set  to TV
if (!$id) {$id = $_POST['id'];}
if (!$tv) $tv = $_POST['tv'];
if (!$value) $value = $_POST['value'];
if ($value == ' ') $value = ";

if ($modx- > getObject('modTemplateVarResource', array('contentid' => $id, 'tmplvarid' = > $tv))) {
$its shapes = $modx- > getObject('modTemplateVarResource', array('contentid' => $id, 'tmplvarid' = > $tv));
} else {
$its shapes = $modx- > newObject('modTemplateVarResource');
$its shapes->set('contentid', $id);

}

$its shapes->set('value', $value);

$its shapes->save();

}



After the user confirmed his e-mail, send it to the page to edit information about yourself:

the 
[[!FormIt? &hooks=`editUserPage` &successMessage=`saved Changes`]]
[[$editPage]]

Accordingly, the snippet editUserPage
Snippet editUserPage
Snippet editUserPage

the 
<?php
// Get the id of the resource from the user profile
$id = $modx->user->getOne('Profile')->get('website');
$name = $_POST['name'];
if ($name == ") $name = ' ';

// And changes made on the page
if ($modx- > runSnippet('editResource',array('resId' => $id, 'pagetitle' => $name, 'longtitle' => $name, 'menutitle' => $name, 'hidemenu' => 'show'))) {
foreach ($_POST as $key => $value) {
switch ($key) {
case 'com_address': $tv = 2; break;
case 'com_egrul': $tv = 5; break;
case 'com_email': $tv = 9; break;
case 'com_federate': $tv = 4; break;
case 'com_head': $tv = 10; break;
case 'com_inn': $tv = 6; break;
case 'com_kpp': $tv = 7; break;
case 'com_phone': $tv = 3; break;
case 'com_regon': $tv = 8; break;
default: $tv = 0; break;
}
if (!$value) $value = ' ';
if ($tv) $modx- > runSnippet('tv', array('id' => $id, 'tv' => $tv, 'value' => $value));
}
// Clear cache so the changes were immediately visible
$modx- > cacheManager- > refresh();
return true;
}



Creating the article or user events


Let us users can add to your page of upcoming and past events:

the 
[[!FormIt? &hooks=`addEvent` &successMessage=`saved Changes` &submitVar=`addEvent`]]
[[$addEventForm]]


Snippet addEvent
Snippet addEvent

the 
<?php
// Events will be child resources of the user's page
$parent = $modx->user->getOne('Profile')->get('website');
$name = $_POST['name'];
$date = explode('.',$_POST['event_date']);
$publishedon = $date[2]."-".$date[1]."-".$date[0]." 10:00:00";
$introtext = $_POST['description'];
if ($id = $modx- > runSnippet('addresource method',array('pagetitle' => $name, 'longtitle' => $name, 'introtext' = > $introtext, 'menutitle' => $name, 'published' = > 1, 'publishedon' => $publishedon, 'parent' => $parent, 'template' => 4, 'isfolder' = > 1))) {

// Fill in any parameters of the event that we need
foreach ($_POST as $key => $value) {
switch ($key) {
case 'event_address': $tv = 14; break;
case 'event_type': $tv = 12; break;
case 'event_org': $tv = 34; break;
case 'event_peoples': $tv = 24; break;
default: $tv = 0; break;
}
if (!$value) $value = ' ';
if ($tv) $modx- > runSnippet('tv', array('id' => $id, 'tv' => $tv, 'value' => $value));
}

$modx- > cacheManager- > refresh();

// Redirect to view events
$url = "/companies/id".$parent."/event".$id;
header('location: '.$url); exit;
return true;
}



eventually

On our website users can register, post information about yourself, create events or write articles.

What I plan to do with it

Next I plan to make the ability for users to upload photos, add functionality for sending and reading private messages, as wrote about Goobs, as well as the ability for users to register for any events.

Approval of WSUS updates: import, export, copy

Изображение
the Backstory Until recently, I worked as edikasyon a major Russian company that has many offices throughout the country. In my jurisdiction there were eleven sites, located in different cities of the Far East (this is important). In each of these offices had its own, not connected with other network infrastructure — your domain AD own subnet, etc. Once the leadership gave me the task to organize the automatic updating of the OS and programs from MS and allowed to expand on accountable sites WSUS . Problem After WSUS was deployed, binding policy, computers to WSUS groups are configured, the directory synchronization content server MS held, etc., the question arose: who and how will approve the update? Imagine 11 cities that are so "fast" and "stable", that rare moment when latency of ICMP replies are only 800 MS, are perceived as unheard of luck. And in each you test all updates before deploying. The access to the servers at the sites was only v

The Hilbert curve vs. Z-order

Repeatedly heard the opinion that of all swept curves . it the Hilbert curve the most promising for spatial indexing. The explanation given is that it does not contain discontinuities and therefore in some sense “well-arranged”. Whether so it actually and what is the spatial indexing, we will understand under the cut. The concluding article of the series: the the Why doesn't the straightforward approach to spatial indexing swept curves the Presentation the 3D and obvious optimization the 8D and perspectives OLAP the 3D field as it looks the 3D field benchmarks the How about indexing non-point objects? The Hilbert curve has the remarkable property — the distance between two successive points is always equal to one (step current of detail, to be precise). Therefore, data is not much different Hilbert curve values are close to each other (the inverse, incidentally, is wrong — adjacent points may be very different in meaning). For this property it is us

Kaspersky Security Center — the fight for automation

oddly enough, I found habré only one article on the subject — the sandbox much unfinished actually contains a piece of the slightly redesigned the product help. Yes, and Google query klakaut silent. I'm not going to tell you how to administer the hierarchy of Kaspersky Security Center (hereinafter KSC) from the command line — I do not yet need never. Just want to share some thoughts about automation tools to those who need it and disassemble one case with which I had to face. If you, %habrauser%, this topic will be interesting — welcome under kat. Historically, the anti-virus protection on the job, I prefer products of Kaspersky Lab (hereafter LK). Causes and other Holy war of personal opinions, I'll leave behind the scenes. Naturally, I would like to centrally deploy, protect, to protect and to enforce the law to draw beautiful graphics to integrate into existing monitoring systems and to do other work shifting the blame to a healthy server. And if you deplo
