Get the 'running' page in hooked property.

Recommended Posts

I'm trying to modify the property 'path' for a specific Page (User, actually) using the following code: 

$this->addHookAfter("Page::path",$this,"modifyUserPagePath");

AND

public function modifyUserPagePath(HookEvent $event){

	$p = $event->object;

	if($p->template == "user" && $p->hasRole("ambassador")){

		die("MODIFY THE PATH HERE WITH PREFIX FOR THE CURRENT VIEWING PAGE");
	}

}

But i'm not able to retrieve the page that is currently running (as in, the page in the browser url).

Please note I'm also using the render() method to render subpages content. I don't need the subpages url but only the original $page requested.

Is there a pretty way to do this (besides looking it up via $_SERVER['REQUEST_URI'] )?

If you need to add a hook only to the current page, you don't need to add it on all Page instances. Instead, you can attach it only to the current page instance:

$page = wire('page');
$page->addHookAfter('path', 'modifyUserPagePath');

Then you don't need your check for the template.

Where are you defining this hook? In an autoload module in the init() method?

If you need to add a hook only to the current page, you don't need to add it on all Page instances. Instead, you can attach it only to the current page instance.

While this is most of the time right it's not working in this case. You can only hook the path function for all pages, but not for single instances.

Reading your question again, I think I didn't fully understand it before ;) You can grab the actual page with

$page = wire('page');

Hmm, sorry. That doesn't work. This still returns the User. To be clear:

I'm echoing $someUser->url on a 'normal' page/template. I want the hook to return the url from the 'normal' page appended with the name field for the user. I'm using urlSegments on the 'normal' template to receive the users name.

There are multiple 'normal' pages that can have the same user as a urlSegment (having them in a Page selecting field on the 'normal' template)

These are the some example values that I would like to return in the hook.

/just-a-page/john-doe/ (when the calling Page is "just-a-page")
/just-a-page/jane-doe/ (when the calling Page is "just-a-page")
/another-page/jane-doe/ (when the calling Page is "another-page")
/yet-another-page/lorem-subpage/john-doe/ (when the calling Page is "yet-another-page/lorem-subpage/")

Of course I could just use this in my 'normal' template:

echo $page->url.$theUser->name;

but I'm always trying to learn, so would like to use the Hook :)

I'm not sure if this is such a good idea in this case, as hooking the path can be quite a performance hit, but maybe you could do it this way, so normal pages aren't hooked:

$this->addHookAfter("User::path", $this, "modifyUserPagePath");

AND

public function modifyUserPagePath(HookEvent $event){

	$user = $event->object;
        $page = wire('page');

	if($p->hasRole("ambassador")){

		$event->return = $page->url.$user->name."/";

	}

}

Thanks. I ended up just manually constructing the needed url in the template. Wasn't used as much as I thought so it beats the performance impact the Hook would have.

      This is a new module that provides a simple solution to clearing all your cache layers at once, and an extensible interface to perform various cache-related actions.
      The simple motivation behind this module was that I was tired of manually clearing caches in several places after deploying a change on a live site. The basic purpose of this module is a simple Clear all caches link in the Setup menu which clears out all caches, no matter where they hide. You can customize what exactly the module does through it's configuration menu:
      Expire or delete all cache entries in the database, or selectively clear caches by namespace ($cache API) Clear the the template render cache. Clear out specific folders inside your site's cache directory (/site/assets/cache) Refresh version strings for static assets to bust client-side browser caches (this requires some setup, see the full documentation for details). This is the basic function of the module. However, you can also add different cache management action through the API and execute them through the module's interface. For this advanced usage, the module provides:
      An interface to see all available cache actions and execute them. A system log and logging output on the module page to see verify what the module is doing. A CacheControlTools class with utility functions to clear out different caches. An API to add cache actions, execute them programmatically and even modify the default action. Permission management, allowing you granular control over which user roles can execute which actions. The complete documentation can be found in the module's README.
      Beta release
      Note that I consider this a Beta release. Since the module is relatively aggressive in deleting some caches, I would advise you to install in on a test environment before using it on a live site.
      Let me know if you're getting any errors, have trouble using the module or if you have suggestions for improvement!
      In particular, can someone let me know if this module causes any problems with the ProCache module? I don't own or use it, so I can't check. As far as I can tell, ProCache uses a folder inside the cache directory to cache static pages, so my module should be able to clear the ProCache site cache as well, I'd appreciate it if someone can test that for me.
      Future plans
      If there is some interest in this, I plan to expand this to a more general cache management solution. I particular, I would like to add additional cache actions. Some ideas that came to mind:
      Warming up the template render cache for publicly accessible pages. Removing all active user sessions. Let me know if you have more suggestions!

      This module is (yet another) way for implementing a cookie management solution.
      Of course there are several other possibilities:
      - https://processwire.com/talk/topic/22920-klaro-cookie-consent-manager/
      - https://github.com/webmanufaktur/CookieManagementBanner
      - https://github.com/johannesdachsel/cookiemonster
      - https://www.oiljs.org/
      - ... and so on ...
      In this module you can configure which kind of cookie categories you want to manage:

      You can also enable the support for respecting the Do-Not-Track (DNT) header to don't annoy users, who already decided for all their browsing experience.
      Currently there are four possible cookie groups:
      - Necessary (always enabled)
      - Statistics
      - Marketing
      - External Media
      All groups can be renamed, so feel free to use other cookie group names. I just haven't found a way to implement a "repeater like" field as configurable module field ...
      When you want to load specific scripts ( like Google Analytics, Google Maps, ...) only after the user's content to this specific category of cookies, just use the following script syntax:
      <script type="optin" data-type="text/javascript" data-category="statistics" data-src="/path/to/your/statistic/script.js"></script> <script type="optin" data-type="text/javascript" data-category="marketing" data-src="/path/to/your/mareketing/script.js"></script> <script type="optin" data-type="text/javascript" data-category="external_media" data-src="/path/to/your/external-media/script.js"></script> <script type="optin" data-type="text/javascript" data-category="marketing">console.log("Inline scripts are also working!");</script> The type has to be "optin" to get recognized by PrivacyWire, the data-attributes are giving hints, how the script shall be loaded, if the data-category is within the cookie consents of the user. These scripts are loaded asynchronously after the user made the decision.
      If you want to give the users the possibility to change their consent, you can use the following Textformatter:
      [[privacywire-choose-cookies]] It's planned to add also other Textformatters to opt-out of specific cookie groups or delete the whole consent cookie.
      You can also add a custom link to output the banner again with a link / button with following class:
      <a href="#" class="privacywire-show-options">Show Cookie Options</a> <button class="privacywire-show-options">Show Cookie Options</button> This module is still in development, but we already use it on several production websites.
      You find it here: https://github.com/blaueQuelle/privacywire/tree/master

      I would love to hear your feedback 🙂

      Admin Page Tree Multiple Sorting
      ClassName: ProcessPageListMultipleSorting
      Extend the ordinary sort of children of a template in the admin page tree with multiple properties. For each template, you can define your own rule. Write each template (template-name) in a row, followed by a colon and then the additional field names for sorting.
      Example: All children of the template "blog" to be sorted in descending order according to the date of creation, then descending by modification date, and then by title. Type:
      blog: -created, -modified, title  Installation
      Copy the files for this module to /site/modules/ProcessPageListMultipleSorting/ In admin: Modules > Check for new modules. Install Module "Admin Page Tree Multible Sorting". Alternative in ProcessWire 2.4+
      Login to ProcessWire backend and go to Modules Click tab "New" and enter Module Class Name: "ProcessPageListMultipleSorting" Click "Download and Install"   Compatibility   I have currently tested the module only under PW 2.6+, but think that it works on older versions too. Maybe someone can give a feedback.     Download   PW-Repo: http://modules.processwire.com/modules/process-page-list-multiple-sorting/ GitHub: https://github.com/FlipZoomMedia/Processwire-ProcessPageListMultipleSorting     I hope someone can use the module. Have fun and best regards, David

      Hello,
      this module can publish content of a Processwire page on a Facebook page, triggered by saving the Processwire page.
      To set it up, configure the module with a Facebook app ID, secret and a Page ID. Following is additional configuration on Facebook for developers:
      Minimum Required Facebook App configuration:
      on Settings -> Basics, provide the App Domains, provide the Site URL, on Settings -> Advanced, set the API version (has been tested up to v3.3), add Product: Facebook Login, on Facebook Login -> Settings, set Client OAuth Login: Yes, set Web OAuth Login: Yes, set Enforce HTTPS: Yes, add "https://www.example.com/processwire/page/" to field Valid OAuth Redirect URIs. This module is configurable as follows:
      Templates: posts can take place only for pages with the defined templates. On/Off switch: specify a checkbox field that will not allow the post if checked. Specify a message and/or an image for the post.
      Usage
      edit the desired PW page and save; it will post right after the initial Facebook log in and permission granting. After that, an access token is kept.
       
      Download
      PW module directory: http://modules.processwire.com/modules/auto-fb-post/ Github: https://github.com/kastrind/AutoFbPost   Note: Facebook SDK for PHP is utilized.
