Markup RSS Enhanced

Recommended Posts

This Module didn't have it's real own thread, now it has :-)


Markup RSS Enhanced

This Module is the enhanced version of Ryan's Markup RSS Module and is completely compatible with it. In addition, this enhanced module supports the usage of enclosures a way of attaching multimedia content to RSS feeds. Give the RSS enhanced module a PageArray of pages and it will render a RSS feed from it. The Module should be used directly from your template file.

In the examples the $rss variable is used for as instance of the module.

$rss = $modules->get("MarkupRSSEnhanced");

Basic usage

In case you only need 1 feed for your site, you need to setup the defaults in the Modules config. then you can use the code below.

$items = $pages->find("limit=10, sort=-modified");  // $items, PageArray of Pages
$rss = $modules->get("MarkupRSSEnhanced");          // load the module
$rss->render($items);                               // render the feed 

Setup channel elements

The channel element describes the RSS feed. There are 3 required channel elements:

  1. title $rss->title
  2. link $rss->url
  3. description $rss->description
$rss->title = '';       // (string) Title of the feed.
$rss->url = '';         // (string) URL of the website this feed lives. Example: http://www.your-domain.com/
$rss->description = ''; // (string) Phrase or sentence describing the channel.
$rss->copyright = '';   // (string) Copyright notice for content in the channel.
$rss->ttl = '';         // (string/integer) Number of minutes that how long it can be cached.

Setup item elements

Every page from the PageArray use the item element.

$rss->itemTitleField = '';             // Fieldname to get value from
$rss->itemDescriptionField = '';       // Fieldname to get value from
$rss->itemDescriptionLength = '';      // Default 1024
$rss->itemEnclosureField = '';         // Fieldname to get file/image from
$rss->itemDateField = '';              // Fieldname to get data from
$rss->itemLinkField = '';              // Fieldname to get URL from or don't set to use $page->httpUrl
$rss->itemAuthorField = '';            // If email address is used, itemAuthorElement should be set to author
$rss->itemAuthorElement = 'dc:creator' // may be 'dc:creator' or 'author'

Item element enclosure

RSS enclosures are a way of attaching multimedia content to RSS feeds. All files with proper mime types are supported. If you asign an image field to the itemEnclosureField there are 3 extra options you could set.

  1. width The width of the image.
  2. height The height of the image.
  3. boundingbox Checking boundingbox will scale the image so that the whole image will fit in the specified width & height. This prevents cropping the image
$rss->boundingbox = 1 // (integer) 1 or 0, on or off
$rss->width = 400;    // (integer) Max width of the image, 0 for proportional
$rss->height = 300;   // (integer) Max height of the image, 0 for proportional 

Prettify the feed

Prettifying the feed is not supported by all clients.

$rss->xsl = ''; // path to xls file
$rss->css = ''; // path to css

Hi, I'm trying using this module with latest PW release but I got this error:

Error: Call to undefined function finfo_open() (line 253 of /home/ilpepe/public_html/site/modules/MarkupRSSEnhanced.module)

@Martijn: maybe a check on install of the module or in the config-screen?

if( !extension_loaded('fileinfo') && !@dl('fileinfo') ) {
    // missing PHP extension
    ...
}

@Sevarf2, would you mind to try the following ?

Add a new method somewhere in the module:

    /**
     * Return Mimetype
     *
     */
    protected function mimetype($filename) {

        if (function_exists('finfo_open')) {
            $info = finfo_open(FILEINFO_MIME_TYPE);
            $mime = finfo_file($info, $filename);
            finfo_close($info);
        } else if (function_exists('mime_content_type')) {
            $mime = mime_content_type($filename);
        } else {
            $mime = 'application/octet-stream';
        }

        return $mime;
    }
And then change the code for the mime type:
/* Disable this: */
// $info = finfo_open(FILEINFO_MIME_TYPE);
// $mime = finfo_file($info, $field->filename);
// finfo_close($info);

/* add this: */
$mime = $this->mimetype($field->filename);

The Module should be used directly from your template file.

What template file? I have rss.php in my templates directory. How is the feed accessed? I need to make a blank RSS template in PW?

Never mind that worked

Is there a way to append $rss->itemLinkField = ''; ? For use with campaign url or other tracking methods.

E.g. such as this:

$rss->itemLinkField = 'httpUrl' . '?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication';

Except that this wont work … I have also tried:

$rss->itemLinkField = 'httpUrl';
$rss->itemLinkField .= '?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication';

Just to show what is not working, and what I am trying to achieve.

Hey, I sent a pull request to fix parsing error with message 'unicode entity not defined' when using author field that contains unicode (Turkish) characters. I also added atom namespace and atom:link property under channel to pass W3C validation.

I was just using this module "MarkupRSSEnhanced" to generate my rss feed.
My RSS feed specifically pulls data from 2 different templates.

Though both these templates have the same title field called 'Title', their description field varies (one has r_desc and the other has e_desc)

Is there a way where I can configure the model in such a way to pick up either of r_desc or e_desc (whichever is present on the template)
I also have the same problem with adding the image to rss also since one has field name r_pic and the other has e_pic.
PS-I cannot change the field names since I recently took over the project I am working on and it has been implemented by many others before me.

@Alex CA you can change those fields when you instantiate the module:

$rss = $modules->get("MarkupRSSEnhanced");
$rss->title = 'Title for this feed';
$rss->description = 'Description for this feed';
$rss->itemDescriptionField = 'r_desc'; // set your specific field here, e.g. r_desc or e_desc
$rss->itemEnclosureField = 'r_pic'; // or e_pic

$limit = 8;
$items = $page->children("limit={$limit}, sort=-publish_start");
$rss->render($items);

I did see how to instantiate the module. But how do I make module pick up r_desc and r_pic when it's generating the RSS feed when I select pages with template='Template1'  and then make it pick e_desc and e_pic when the template is='Template2'.
My condition for the page selector for my RSS feed is $pages->find("template=". $template1 ."|". $template2.", sort=-modified,limit=20");

I think if i was faced with your situation, the first thing i would do (after cursing out the developer who setup that field structure) would be to add a runtime field and see if the module is able to pick up that: (in ready.php for example):

wire()->addHookProperty('Page(template=Template1)::rss_desc', function($event) {
    $page = $event->object;
    $event->return =  $page->r_desc;
});

wire()->addHookProperty('Page(template=Template2)::rss_desc', function($event) {
    $page = $event->object;
    $event->return =  $page->e_desc;
});

wire()->addHookProperty('Page(template=Template1)::rss_pic', function($event) {
    $page = $event->object;
    $event->return =  $page->r_pic;
});

wire()->addHookProperty('Page(template=Template2)::rss_pic', function($event) {
    $page = $event->object;
    $event->return =  $page->e_pic;
});

Or I would just roll my own RSS feed using a class..

@Macrura
Thanks for all the help. The addHookProperty() did not work. Another simple solution (I should've tried it earlier ) is to directly use 

$rss->itemDescriptionField='e_desc|r_desc'

I do have another task what I am trying to solve with the help of RSS module.

Suppose my rss feed is based on a page which uses template A and it is pulling data from all templates on the website which has template B (which is say b_title and b_description). Now, I have another field in template B which has a filed type Page(lets called this field b_page) which essentially is for pages of another template (let's call it template C).This template C consists of a field called c_img. Now I want my rss feed template(A.php) to pull the title and description from template B and the image for the rss feed from template C. How do I achieve the retrieval of the image? 
I have tried representing my problem with a picture below.
 

My current code looks similar to this:

<?php

// rss-feed.php template file
// retrieve the RSS module
$rss = $modules->get("MarkupRSSEnhanced");
// configure the feed. see the actual module file for more optional config options.
$rss->title = "Latest updates";
$rss->description = "The most recent pages ";



$items = $pages->find("tempalte=". $templateB .", sort=-modified,limit=20");
$rss->itemDescriptionField = 'b_Desc';
$rss->itemEnclosureField = 'b_page[0]->c_img'; // we take the first one since this field can consist an array of pages         
// send the output of the RSS feed, and you are done
$rss->render($items); 

?>

      Wire Mail SMTP

      An extension to the new WireMail base class that uses SMTP-transport

      This module integrates EmailMessage, SMTP and SASL php-libraries from Manuel Lemos into ProcessWire. I use this continously evolved libraries for about 10 years now and there was never a reason or occasion not to do so. I use it nearly every day in my office for automated composing and sending personalized messages with attachments, requests for Disposition Notifications, etc. Also I have used it for sending personalized Bulkmails many times.

      The WireMailSmtp module extends the new email-related WireMail base class introduced in ProcessWire 2.4.1 (while this writing, the dev-branch only).
       
      Here are Ryans announcement.



      Current Version 0.3.0
      get it from the Modules Directory Install and Configure

      Download the module into your site/modules/ directory and install it.

      In the config page you fill in settings for the SMTP server and optionaly the (default) sender, like email address, name and signature.
      You can test the smtp settings directly there. If it says "SUCCESS! SMTP settings appear to work correctly." you are ready to start using it in templates, modules or bootstrap scripts.


      Usage Examples
      The simplest way to use it:
      $numSent = wireMail($to, $from, $subject, $textBody); $numSent = wireMail($to, '', $subject, $textBody); // or with a default sender emailaddress on config page This will send a plain text message to each recipient.
       
      You may also use the object oriented style:
      $mail = wireMail(); // calling an empty wireMail() returns a wireMail object $mail->to($toEmail, $toName); $mail->from = $yourEmailaddress; // if you don't have set a default sender in config // or if you want to override that $mail->subject($subject); $mail->body($textBody); $numSent = $mail->send(); Or chained, like everywhere in ProcessWire:
      $mail = wireMail(); $numSent = $mail->to($toEmail)->subject($subject)->body($textBody)->send(); Additionaly to the basics there are more options available with WireMailSmtp. The main difference compared to the WireMail BaseClass is the sendSingle option. With it you can set only one To-Recipient but additional CC-Recipients.
      $mail = wireMail(); $mail->sendSingle(true)->to($toEmail, $toName)->cc(array('person1@example.com', 'person2@example.com', 'person3@example.com')); $numSent = $mail->subject($subject)->body($textBody)->send(); The same as function call with options array:
      $options = array( 'sendSingle' => true, 'cc' => array('person1@example.com', 'person2@example.com', 'person3@example.com') ); $numSent = wireMail($to, '', $subject, $textBody, $options); There are methods to your disposal to check if you have the right WireMail-Class and if the SMTP-settings are working:
      $mail = wireMail(); if($mail->className != 'WireMailSmtp') { // Uups, wrong WireMail-Class: do something to inform the user and quit echo "<p>Couldn't get the right WireMail-Module (WireMailSmtp). found: {$mail->className}</p>"; return; } if(!$mail->testConnection()) { // Connection not working: echo "<p>Couldn't connect to the SMTP server. Please check the {$mail->className} modules config settings!</p>"; return; } Following are a ...


      List of all options and features


      testConnection () - returns true on success, false on failures


      sendSingle ( true | false ) - default is false

      sendBulk ( true | false ) - default is false, Set this to true if you have lots of recipients (50+)


      to ($recipients) - one emailaddress or array with multiple emailaddresses

      cc ($recipients) - only available with mode sendSingle, one emailaddress or array with multiple emailaddresses

      bcc ($recipients) - one emailaddress or array with multiple emailaddresses

       
      from = 'person@example.com' - emailaddress, can be set in module config (called Sender Emailaddress) but it can be overwritten here

      fromName = 'Name Surname' - optional, can be set in module config (called Sender Name) but it can be overwritten here


      priority (3) - 1 = Highest | 2 = High | 3 = Normal | 4 = Low | 5 = Lowest

      dispositionNotification () or notification () - request a Disposition Notification


      subject ($subject) - subject of the message

      body ($textBody) - use this one alone to create and send plainText emailmessages

      bodyHTML ($htmlBody) - use this to create a Multipart Alternative Emailmessage (containing a HTML-Part and a Plaintext-Part as fallback)

      addSignature ( true | false ) - the default-behave is selectable in config screen, this can be overridden here
      (only available if a signature is defined in the config screen)

      attachment ($filename, $alternativeBasename = "") - add attachment file, optionally alternative basename


      send () - send the message(s) and return number of successful sent messages


      getResult () - returns a dump (array) with all recipients (to, cc, bcc) and settings you have selected with the message, the message subject and body, and lists of successfull addresses and failed addresses,


      logActivity ($logmessage) - you may log success if you want

      logError ($logmessage) - you may log warnings, too. - Errors are logged automaticaly
       
       
      useSentLog (true | false) - intended for usage with e.g. third party newsletter modules - tells the send() method to make usage of the sentLog-methods - the following three sentLog methods are hookable, e.g. if you don't want log into files you may provide your own storage, or add additional functionality here

      sentLogReset ()  - starts a new LogSession - Best usage would be interactively once when setting up a new Newsletter

      sentLogGet ()  - is called automaticly within the send() method - returns an array containing all previously used emailaddresses

      sentLogAdd ($emailaddress)  - is called automaticly within the send() method

      This module provides a very simple interface to a set of named counters. You simply call a single function, next('name'), to pull the next value out of a counter - or to set it up if it does not yet exist. Next() takes a few extra parameters to allow you to increment by values other than 1 or to start at a certain number.
      This provides some similar functionality to the built-in page naming feature of PW, and to this module recently posted by Stikki but I think it offers a little more flexibility than either. Having said that, I do like the simplicity of Stikki's new auto-increment module.
      Module Availability
      Here is my module on Github.
      Here it is in the module repository.
      Example Usage
      Here's how this module can be used to title and name a new page by adding a couple of simple hooks to site/ready.php. This example applies to new pages using a template called 'invoice' that can be quick-added to the page tree. In order to get the following to work, you must edit the template that will be the parent of the 'invoice' template and setup the template for children to "invoice" and set the "Name Format for Children" field to something other than the default blank value (I use  title  as my value.)
      <?php /** * Function to recognise our special template. */ function isInvoiceTemplate($template) { return ($template == 'invoice'); } /** * Pre-load the page title for invoice pages with a unique value * which includes a counter component. */ $pages->addHookBefore("Pages::setupNew", function($event) { $page = $event->arguments(0); $is_invoice = isInvoiceTemplate($page->template); $no_inv_num = $page->title == ''; if ($is_invoice && $no_inv_num) { $counter_name = 'WR-' . date('Y'); $number = $this->modules->get('DatabaseCounters')->next($counter_name, 10, 5000); $page->title = $counter_name . '-' . sprintf("%06u", $number); } }); /** * Prevent ProcessPageEdit from forcing an edit of the name if we got here * through a quickAdd from ProcessPageAdd. We can do this because we * preset the title field in the Pages::setupNew hook. */ $pages->addHookAfter("ProcessPageEdit::loadPage", function($event) { $page = $event->return; $is_invoice = isInvoiceTemplate($page->template); $is_temp = $page->hasStatus(Page::statusTemp); if ($is_invoice && $is_temp) { $page->removeStatus(Page::statusTemp); $event->return = $page; } }); Note, the above code + module is one direct solution to the problem posted here by RyanJ.

      PulsewayPush
      Send "push" from ProcessWire to Pulseway.
       
      Description
      PulsewayPush simply send a push to a Pulseway instance. If you are using this module, you probably installed Pulseway on your mobile device: you will receive notification on your mobile.
      To get more information about Pulseway, please visit their website.
      Note
      They have a free plan which include 10 notifications (push) each day.
       
      Usage
      Install the PulsewayPush module.
      Then call the module where you like in your module/template code :
      <?php $modules->get("PulsewayPush")->push("The title", "The notification message.", "elevated"); ?>  
      Hookable function
      ___push() ___notify() (the two function do the same thing)
       
      Download
      Github:  https://github.com/flydev-fr/PulsewayPush Modules Directory: https://modules.processwire.com/modules/pulseway-push/  
      Examples of use case
      I needed for our work a system which send notification to mobile device in case of a client request immediate support. Pulseway was choosen because it is already used to monitor our infrastructure.
      An idea, you could use the free plan to monitor your blog or website regarding the number of failed logins attempts (hooking Login/Register?), the automated tool then block the attacker's IP with firewall rules and send you a notification.

      2017-11-22: added the module to the modules directory
       
    • By cosmicsafari
      Hi all,
      Just wondering if its possible to just add some basic output to my modules config page.
      I was wanting to output a bulleted list of some information which I will be pulling from a third party.
      Retrieving the data is fine i'm just not sure how to output it to the config page?
      From what I can see in the link below, it only seems like you can append form items to the page.
