Pages2JSON

Recommended Posts

Where do i get?

From here: https://github.com/IDT-media/Pages2JSON (thanks to LostKobrakai for "bug" report)

What does this do?

Simply adds method toJSON() to Page and PageArray elements, is capable to converting image and file arrays to URL containers, travels recursively all objects before outputs actual JSON.

How to use?

Simply install this module, configure data you want it to export in JSON result (similar to Ryan's ServicePages, thanks btw used some of ur code here). in templates or anywhere you need JSON output, call: $page->toJSON(); or $pages->toJSON();

Live example with template: search.php

/*****************************************************************
 Do search
*****************************************************************/

$term = $sanitizer->text($input->term);
$results = array();

if($term) {

    $input->whitelist('term', $term);

    $term = $sanitizer->selectorValue($term);
    
    $limit = (int)$input->limit;
    $limit = $limit ? $limit : 50;
    $limit = $sanitizer->selectorValue($limit);     
    
    $selector = "title|categories|content*=$term, limit=$limit, template=default|product";

    // Prevent admin pages.
    if($user->isLoggedin()) $selector .= ", has_parent!=2";

    // Find pages that match the selector
    $results = $pages->find($selector);
}

/*****************************************************************
 Output
*****************************************************************/

header("Content-type: application/json");
echo $results->toJSON();
exit();

Customizing values:

if(wire('config')->ajax) {
    wire()->addHookAfter('Pages2JSON::getValue', function($event) {

        $value = $event->arguments(0);
    
        if(!is_object($value))
            return;
        
        $page = wire('page');
        if($page->template == 'thumbs' && $value->className == 'Pageimage')
            $event->return = $value->size(28,28)->url;
        
    });
}

Here i swap URL of all Pageimage objects in JSON response to match thumbs. Simple hu?

A link to your module would make it easier for people to use it :)

Heyyy, awesome IDEA!

Hi. thx for a module :), i wonder is there a way to include translation fields as well. Textarea (default) + other languages, and so on.

Hi. thx for a module :), i wonder is there a way to include translation fields as well. Textarea (default) + other languages, and so on.

Well, it just reads attached fields and outputs data as fields provide it in that context, i didn't test with MLE fields, but i would assume output is in language that is currently in use as this is purely just JSON parser, it doesn't change data anyhow by default. If this behavior ain't correct in your opinion, please open ticket to Github and i'll take a look.

Hello Stikki.

   Is there a way to get the title of images or files?

By the way, thank you for the fantastic module.

You can try override default behavior:

wire()->addHookAfter('Pages2JSON::getValue', function($event) {

	$value = $event->arguments(0);

	if(!is_object($value))
		return;
	
	if($value->className == 'Pageimage') {
	
		$obj = new stdClass;
		$obj->url 		= $value->url;
		$obj->description 	= $value->description;

		$event->return = $obj;		
	}	
});

Didn't test this btw, you could let ppl know if it works, thanks.

I added in line 138 of the module those lines to get lat, lng, zoom, address and descriptions of images and files

protected function ___getValue($value)
{
if(!is_object($value))
return $value;

switch($value->className) {

case 'Page':
return $this->toPage($value);

case 'Pageimage':
case 'Pagefile':
return array("url"=>$value->url, "description"=>$value->description);

case 'Pagefiles':
case 'Pageimages':
case 'PageArray':
case 'WireArray':
return $this->toArray($value);
case 'MapMarker':
return array("lat"=>$value->lat, "lng"=>$value->lng, "zoom"=>$value->zoom, "address"=>$value->address);
}

return null;
}

Was MapMarker currently core module? If so i'll add it then.

Okey, i'll consider it but since it's not currently core module use own custom version of this or alter it by hooking, if more people vote for MapMarker it gets in more likely, thanks for awesome documentation tho.

However i'll change file and image files to support description by default just like you suggested.

Those who already use this module, notice that this will break your JSON streams when it comes to files and images.

I just installed your module in the latest 3.0.7 dev. It works as expected when accessing a page as guest, but when I'm logged in as admin, I get JSON output from richtext-fields like this:

summary: "<div id=pw-edit-2 class='pw-edit pw-edit-InputfieldTextarea' data-name=summary data-page=1001 style='position:relative'><div class=pw-edit-orig>This is a placeholder page with two child pages to serve as an example. </div><div class=pw-edit-copy id=pw-editor-summary-1001 style='display:none;-webkit-user-select:text;user-select:text;' contenteditable>This is a placeholder page with two child pages to serve as an example. </div></div>",

I don't remember this module doing this in 2.x versions... if you get the chance, could you find out what's causing this?

Oh, and also: fieldtype Matrix Repeater is completely ignored. Is that fieldtype too complex to render as JSON?

Howdy dragan,

Will look into this matter when i start testing with 3.x series, haven't touched that yet.

And what comes to Matrix repeater, it only works with standard fields currently, special fields would require own checkpoint, and since haven't used Matrix repeater myself yet, there is no check for that. You can always hook to getValue() method and implement you own check without hacking module.

The markup seems to be by the frontend editing feature, which explains why it's only for logged in users. The internals of matrix repeaters are quite complex and will probably need a special implementation, because it's using a single template for all the different types of data (which doesn't make sense in my mind, but so be it).

OK, turns out the Front-End Page Editor module is injecting PW-backend specific stuff (all over the place) - in the HTML source too, not just when doing echo $page->body etc.

For now (for 3.x tests) I'll use something like this, when I need JSON output:

if($input->urlSegment1 === 'json') {
	header("Content-type: application/json");

	$ar['title'] 		= $page->title;
	$ar['body'] 		= $page->body;
	$ar['summary'] 		= $page->summary;
	$ar['created'] 		= $page->created;
	$ar['modified'] 	= $page->modified;

        // new way how to render fields (optional) - with "baby" templates for each field
	$ar['matrix_test'] 	= $page->render('matrix_test');

	$output = json_encode($ar);
	echo $output;
	exit();
}

So this is turning another Drupal? Shame.

https://processwire.com/blog/posts/front-end-editing-now-in-processwire-3.0-alpha-4/

"All of the front-end editing features are provided by a module included with the ProcessWire 3.0 core called PageFrontEdit. Once this module is installed, you can use any of the above options. The module is not installed by default."

So it is not turning Drupal.

Great module! It came in handy and saved me a lot of work from building my own JSON. Thanks!

I do need to modify the output and I am struggling to understand how to do so.  By default, the http host is not appended to any url and I need that for this particular project. I figured this would be a simple fix, but can't find where to alter that particular value. If you reference the json below, you will see the file node with the url displayed. There are two other nodes that I need to alter the same. Images and video. Any tips are appreciated.

//original code
$items = $pages->findMany("template=item"); 
echo $items->toJSON();
{
        "pages": [
            {
                "id": 1033,
                "title": "Page 1"
            },
            {
                "id": 1116,
                "title": "Page 2"
            }
        ],
        "categories": [
            {
                "id": 1031,
                "title": "Brochures"
            },
            {
                "id": 1036,
                "title": "Photos"
            }
        ],
        "file": {
            "description": "File 1",
            "url": "/site/assets/files/1039/file1.pdf"
        },
        "id": 1039,

So I figured it out and here is my complete code if it would help anyone else. 

//get the pages you want
$items = $pages->findMany("template=item"); 

wire()->addHookAfter('Pages2JSON::getValue', function($event) {
	//get the host
   	$host = wire('config')->httpHost;
    $value = $event->arguments(0);
    if(!is_object($value))
        return;
	//check if field is an image, images or file type
    if($value->className == 'Pageimage' || $value->className == 'Pagefile') {
		//append the host to those values
       $urls = array("url" => $host . $value->url, "description" => $value->description);
       $event->return = $urls;
    }
        
});

header('Access-Control-Allow-Origin: *');
header('Content-Type: application/json');
echo $items->toJSON();
exit();

Thanks again for the great plugin.

I am trying to get this to work with Kongondo's Media Manager Module. Unfortunately I can't get the url/description to return. I have modified the plugin with no luck, It still returns null.  Anyone had any luck with these two?

I'm trying out this module as well. I was able to add support for SelectableOption and SelectableOptionArray.

Then I ran into an infinite loop. 

I'm using @Robin S's ConnectPages to connect some of my templates, and it would go on until it reaches max exec time. For example:

Jane (Page)
	- Progenitors (Page Multiple)
		- John (Page)

John (Page)
	- Progeny (Page Multiple)
		- Jane (Page)

 

So when it's iterating over Jane's fields, it would come into it's progenitor field which is a multi page field, and would start listing John's fields. In there it would come into John's progeny field and would start listing Jane's data again, and would find John... and so on..

Would anyone have an idea on how to stop the loop from going over and over, or a way to stop the recursion from going too deep? I'd appreciate any help. Thanks.

When looping over the pages in a Page field, set some property to the Page object to serve as an indicator that the page has been processed. Then put your code that processes the pages inside an if() condition that checks that the property has not already been set. So something like:

if(!$page->processed) {
    // do your processing here
    // ...
    $page->processed = true;
}

Thanks Robin. I was able to make it work with some modifications by just returning the ids (instead of the whole page) for pagefields.

Another concern I have is that the json response that I get has [] brackets at the end.

Sample:

{
  "id":1058,
  "firstname":"Julie Ann Mae",
  "sex":[1],
  "birthdate":768931200,
  "nationality":[93],
  "guardians":[1059,1060]
}[]

Is this normal behavior? I can't figure out where it gets inserted. It's been returning that from the beginning.

 

EDIT: I got it. It was totally my fault. :) Thanks

I am trying to make this module work, but I am stuck with this message:

Uncaught ArgumentCountError: Too few arguments to function Pages2JSON::___getFields(), 0 passed in …/site/modules/Pages2JSON/Pages2JSON.module on line 182

What did I make wrong?

  $term = "update";
  $results = array();
  $limit = 3;
  $selector = "title*=$term, limit=$limit, template=entry";
  $results = $pages->find($selector);

  header("Content-type: application/json");
  echo $results->toJSON();
  exit();

      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)
      - Functional
      - 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="text/plain" data-type="text/javascript" data-category="statistics" data-src="/path/to/your/statistic/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing" data-src="/path/to/your/mareketing/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="external_media" data-src="/path/to/your/external-media/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing">console.log("Inline scripts are also working!");</script> The data-attributes (data-type and data-category) are required 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>  
      I would love to hear your feedback 🙂
      CHANGELOG

      As we often use Matomo (former known as Piwik) instead of Google Analytics we wanted to embed Matomo not only in the template code but also via the ProcessWire backend.
      That's why I developed a tiny module for the implementation.
      The module provides the possibility to connect to an existing Matomo installation with the classical site tracking and also via the Matomo Tag Manager.
      If you have also PrivacyWire installed, you can tell MatomoWire to only load the script, if the user has accepted cookies via PrivacyWire.
      To offer an Opt-Out solution you can choose between the simple Opt-Out iFrame, delivered by your Matomo installation, or a button to choose cookies via PrivacyWire.
      You'll find the module both in the module directory and via github:
      ProcessWire Module Directory MatomoWire @ GitHub MatomoWire @ Packagist ->installable via composer require blauequelle/matomowire I'm looking forward to hear your feedback!

      If your module has a lot of config fields you might want to divide them into groups inside a tabbed interface. Here is a demonstration module showing how this can be done.

      Hello community!

      I want to share a new module I've been working on that I think could be a big boost for multi-language ProcessWire sites.

      Some background, I was looking for a way for our company website to be efficiently translated as working with human translators was pretty laborious and a lack of updating content created a divergence between languages. I, and several other devs here, have talked about translation integrations and have recognized the power that DeepL has. DeepL is an AI deep learning powered service that delivers translation quality beyond any automated service available. After access to the API was opened up to the US, I built Fluency, a DeepL translation integration for ProcessWire.
      Fluency brings automated translation to every multi-language field in the admin, and also provides a translation tool allowing the user to translate their text to any language without it being inside a template's field. With Fluency you can:
      Translate any plain textarea or text input Translate any CKEditor content (yes, with markup) Translate page names for fully localized URLs on every page Translate your in-template translation function wrapped strings Translate modules DeepL offers translations to the following languages: English (US), English (UK), German, French, Spanish, Portuguese (EU), Portuguese (Brazil, Italian, Dutch, Polish, Russian, Japanese, Chinese (Simplified)
      Installation and usage is completely plug and play. Whether you're building a new multi-language site, need to update a site to multi-language, or simply want to stop manually translating a site and make any language a one-click deal, it could not be easier to do it. Fluency works by having you match the languages configured in ProcessWIre to DeepL's. You can have your site translating to any or all of the languages DeepL translates to in minutes (quite literally).
      Let's break out the screenshots...
      When the default language tab is shown, a message is displayed to let users know that translation is available. Clicking on each tab shows a link that says "Translate from English". Clicking it shows an animated overlay with the word "Translating..." cycling through each language and a light gradient shift. Have a CKEditor field? All good. Fluency will translated it and use DeepL's ability to translate text within HTML tags. CKEditor fields can be translated as easily and accurately as text/textarea fields.

      Repeaters and AJAX created fields also have translation enabled thanks to a JavaScript MutationObserver that searches for multi-language fields and adds translation as they're inserted into the DOM. If there's a multi-language field on the page, it will have translation added.

      Same goes for image description fields. Multi-language SEO friendly images are good to go.

      Creating a new page from one of your templates? Translate your title, and also translate your page name for native language URLs. (Not available for Russian, Chinese, or Japanese languages due to URL limitations). These can be changed in the "Settings" tab for any page as well so whether you're translating new pages or existing pages, you control the URLs everywhere.

      Language configuration pages are no different. Translate the names of your languages and search for both Site Translation Files (including all of your modules)

      Translate all of the static text in your templates as well. Notice that the placeholders are retained. DeepL is pretty good at recognizing and keeping non-translatable strings like that. If it is changed, it's easy to fix manually.

      Fluency adds a "Translate" item to the CMS header. When clicked this opens up a modal with a full translation tool that lets the user translate any language to any language. No need to leave the admin if you need to translate content from a secondary language back to the default ProcessWire language. There is also a button to get the current API usage statistics. DeepL account owners can set billing limitations via character count to control costs. This may help larger sites or sites being retrofitted keep an eye on their usage. Fluency can be used by users having roles given the fluency-translate permission.

      It couldn't be easier to add Fluency to your new or existing website. Simply add your API key and you're shown what languages are currently available for translation from/to as provided by DeepL. This list and all configuration options are taken live from the API so when DeepL releases new languages you can add them to your site without any work. No module updates, just an easy configuration. Just match the language you configured in ProcessWire to the DeepL language you want it to be associated with and you're done. Fluency also allows you to create a list of words/phrases that will not be translated which can prevent items such as brands and company names from being translated when they shouldn't

       
      Limitations:
      No "translate page" - Translating multiple fields can be done by clicking multiple translation links on multiple fields at once but engineering a "one click page translate" is not feasible from a user experience standpoint. The time it takes to translate one field can be a second or two, but cumulatively that may take much longer (CKEditor fields are slower than plain text fields). There may be a workaround in the future but it isn't currently on the roadmap. No "translate site" - Same thing goes for translating an entire website at once. It would be great, but it would be a very intense process and take a very (very) long time. There may be a workaround in the future but it isn't on the roadmap. No current support for Inline CKEditor fields - Handling for CKEditor on-demand hasn't been implemented yet, this is planned for a future release though and can be done. I just forgot about it because I've never really used that feature personally.. Alpha release - This module is in alpha. Releases should be stable and usable, but there may be edge case issues. Test the module thoroughly and please report any bugs via a Gitlab issue on the repository or respond here. Please note that the browser plugin for Grammarly conflicts with Fluency (as it does with many web applications). To address this issue it is recommended that you disable Grammarly when using Fluency, or open the admin to edit pages in a private window where Grammarly may not be loaded. This is an issue that may not have a resolution as creating a workaround may not be possible. If you have insight as to how this may be solved please visit the Gitlab page and file a bugfix ticket.
      Requirements:
      ProcessWire  3.0+ UIKit Admin Theme That's Fluency in a nutshell. A core effort in this module is to create it so that there is nothing DeepL related hard-coded in that would require updating it when DeepL offers new languages. I would like this to be a future-friendly module that doesn't require developer work to keep it up-to-date.
      It's Free
      This is my first real module and I want to give it back to the community as thanks. This is the best CMS I've worked with (thank you Ryan & contributors) and a great community (thank you dear reader). The only cost to use this is a subscription fee for the DeepL Pro API.

      An inputfield module that brings EasyMDE Markdown editor to ProcessWire.
      EasyMDE is a fork of SimpleMDE, for which there is an existing PW module. Inputfield EasyMDE has a few advantages though:
      EasyMDE seems to be more actively developed than SimpleMDE, which hasn't seen any updates for several years. You can define options for Inputfield EasyMDE. Inputfield EasyMDE can be used in Repeater fields and in custom fields for File/Image fields.  
      Inputfield EasyMDE
      EasyMDE (Easy Markdown Editor) as an inputfield for ProcessWire.
      EasyMDE is a Markdown editor with some nice features, allowing users who may be less experienced with Markdown to use familiar toolbar buttons and shortcuts. More information is at the EasyMDE website.

      Installation
      Install the Inputfield EasyMDE module.
      Usage
      Create a new textarea field, and in the "Inputfield Type" dropdown choose "EasyMDE". Save the field and if you like you can then configure the EasyMDE options for the field as described below.
      To convert Markdown to HTML you can install the core TextformatterMarkdownExtra module and apply the textformatter to the field. Alternatively you can use $sanitizer->entitiesMarkdown() on the field value, e.g.
