Module: Video embed for YouTube/Vimeo (TextformatterVideoEmbed)

Recommended Posts

I had several clients request a version of this module that honors the aspect ratio of a video when using the responsive embed method. For now, the module is using a hard-coded 16/9 ratio.

I decided to give it a go myself and forked Ryan's repo. I added functionality to calculate a video's aspect ratio from the oEmbed return values for width and height and made a change to the module's custom db schema to save the aspect ratio. In the (improbable) case the aspect ratio can't be determined, I added a fallback aspect ratio to the module's config. After looking around for a bit, this post about db schema updates for modules with custom databases provided excellent examples on how to handle the schema updates for existing installations. 

The changes have been tested on several live sites (3.0) and the update went without hiccups.

If anyone's interested, here's the commit: https://github.com/[...]/commit/76e9a5e7bba79aef8fae35aaa7a1b7b79e970f90

I'd love to get some feedback on this! Especially from people running this on the 2.7 or 2.8 branch.

If all works well, it'd be great to integrate this into @ryan's official repo at some point.

Great module @ryan :) 

Our client wants support for another video site too, though. So I'm just trying to properly create/extend a module/use hooks for the first time, so as to add an extra embed function.

Supposing I wanted to create support for an additional platform, where would I hook this into (I don't see any hookable functions other than install and uninstall in it)? Is this module extendable?

It's such a small simple module that I think your best bet is just to edit it directly, and perhaps rename it (to avoid it potentially getting overwritten in the future). Remember to rename both the filename i.e. TextformatterMyVideoEmbed.module, and the class name to match. Then do a Modules > Refresh, and install it.

Okidoki, will do that instead :) Thank you.

This module sort of solves the video embed problem - thank you! - but...

1. It doesn't work in combination with HTML Entity Encoder?
2. You lose all YouTube embed customization options.

Normally I add the following to the iframe embed url:

... ?rel=0&showinfo=0&autohide=1&wmode=transparent&modestbranding=1&color=white

That removes unnecessary stuff and makes the video look less youtubey. Is there no way to do that in Processwire?

Is there really no way to force PW or the text editor to just leave iframe code alone? At least from a few trusted sources.

I have tried adding my customization to the module at return $embedCode. ..., but that doesn't work of course. It comes out like this:

Spoiler

<p><div class='TextformatterVideoEmbed' style='position:relative;padding:30px 0 56.25% 0;height:0;overflow:hidden;'><iframe style='position:absolute;top:0;left:0;width:100%;height:100%;' width="480" height="270" src="https://www.youtube.com/embed/Wl4XiYadV_k?feature=oembed" frameborder="0" allowfullscreen></iframe>?rel=0&showinfo=0&autohide=1&wmode=transparent&modestbranding=1&color=white</div></p>

I am not sure whether this is relevant in your case and it is from a while back but just thought to post to see if it helps:

I haven't tried it, but check out this module that allows you to customize the embedded video's settings: 

And regarding this: " It doesn't work in combination with HTML Entity Encoder" - try changing the order of the text formatters.

I would like to combine the module with lazysizes. Is there a way to replace "src" with "data-src" ?

I found a way how to apply lazysizes. Sharing it here in case anyone wants to do the same thing. With the below javascript code you are replacing iframe's "src" with "data-src" and of course adding the lazyload class and you are 100% ready :)

var iframeEl = document.getElementsByTagName('iframe');
for (var i=0; i<iframeEl.length; i++) {
    if(iframeEl[i].getAttribute('src')) {
       iframeEl[i].setAttribute('data-src',iframeEl[i].getAttribute('src'));
       iframeEl[i].removeAttribute('src');
    }
}

$('iframe').addClass('lazyload');

I don't think this is a good solution. By the time your Js runs the iframe may start to load so making it useless.

I think it would be better to edit the module itself, and maybe rename the module to avoid overwrite it later when updating. Or even better, submit a PR with a new setting for lazy load :)

@PWaddict

I also think you shouldn't use javascript, instead do the formatting on the server. I feel I wouldn't trust the JS solution because it might not work as expected under certain circumstances.

I put together a regular expression which might help you build another Textformatter which replaces "src" with "data-src" if thats the only thing to do:

Have a look at the demo here: http://www.phpliveregex.com/p/jkp (On the right, click on preg_replace to see the replacement.)

This is the code:

<?php
preg_replace("/(<iframe.*)src(.*)(youtube|vimeo)/", "$1data-src$2$3", $input_lines);

(During my research I learned from: http://stackoverflow.com/questions/4898192/preg-replace-how-to-replace-only-matching-xxx1yyy-pattern-inside-the-selector)

Hope that helps,
if you need more advice you can also DM me and we will post the result later -

cheers!

PS:

Or like @tpr mentioned you may put that modification directly into a copy of TextformatterVideoEmbed. That way you would have more control. (TextformatterVideoEmbed itself gets the embed code from an oembed url, so you can't easily intercept there ...)

PPS:

Oh, actually a simple str_replace("src=", "data-src=", $embedCode) in a copy of TextformatterVideoEmbed might actually be sufficient!

Thanks @tpr & @blynx for the help.

I replaced the 129 line of the module with this and it's working:

$out = preg_replace("/(<iframe.*)src(.*)(youtube|vimeo)/", "$1data-src$2$3", $out);
$out = str_ireplace('<iframe ', "<iframe class='lazyload' style='position:absolute;top:0;left:0;width:100%;height:100%;' ", $out);

BUT on some fields I'm using the TextformatterMakeLinks module and the videos on that fields aren't loading cause it adds the video links with href inside of data-src.

TextformatterMakeLinks thinks the iframe with the data-src attribute is a text to parse for links. (http://www.phpliveregex.com/p/jkU) It does not get caught by the first regular expression there ...

Either that bug has to be fixed (huh, thats a rather long reg-exp there -.-) - try to contact @interrobang there:

Or you could seperate this 

preg_replace("/(<iframe.*)src(.*)(youtube|vimeo)/", "$1data-src$2$3", $out)

into a new Textformatter and use the original VideoEmbed again.
Then, the order should be:

VideoEmbed
MakeLinks
ThatFormatterWhichMakesTheDataSrc

I think this should work, since MakeLinks detects "src" in an iframe correctly - but not "data-src"

Good luck :)

@blynx Actually I've unistalled TextformatterMakeLinks cause I don't really need it so problem solved. Thanks again for the help.

@ryan Can you update the module with a new option for lazy load? On the module config there must be 2 new fields. A checkbox field for the lazy loading option and a text field with the css class name from the lazy script used. Eg. I'm using lazysizes so the class name is lazyload.

Here is the replaced code on the 129 line of the module:

$out = preg_replace("/(<iframe.*)src(.*)(youtube|vimeo)/", "$1data-src$2$3", $out);
$out = str_ireplace('<iframe ', "<iframe class='lazyload' style='position:absolute;top:0;left:0;width:100%;height:100%;' ", $out);

Hi, i need youtube video id 

Is there any way to get this id from template file.?

I was looking into TextformatterVideoEmbed.module file

public function format(&$str) {
		$this->embedYoutube($str);
		$this->embedVimeo($str);
	}

	/**
	 * Check for Youtube URLS and embed when found
	 *
	 */
	protected function embedYoutube(&$str) {

		// perform a strpos fast check before performing regex check
		if(strpos($str, '://www.youtube.com/watch') === false && strpos($str, '://www.youtube.com/v/') === false && strpos($str, '://youtu.be/') === false) return;

		//               1: full URL                                                 2:video id    3: query string (optional)
		$regex = '#<p>\s*(https?://(?:www\.)?youtu(?:.be|be.com)+/(?:watch/?\?v=|v/)?([^\s&<\'"]+))(&[-_,.=&;a-zA-Z0-9]*)?.*?</p>#';
		if(!preg_match_all($regex, $str, $matches)) return;

		foreach($matches[0] as $key => $line) { 

			$oembedURL = 
				"$this->http://www.youtube.com/oembed?url=" . urlencode($matches[1][$key]) . 
				"&format=json&maxwidth={$this->maxWidth}&maxheight={$this->maxHeight}"; 

			$videoID = $matches[2][$key]; 
			$queryString = isset($matches[3][$key]) ? $matches[3][$key] : '';
			$embedCode = $this->getEmbedCode($oembedURL, $videoID); 

 

Can i use something like below  from my template file

$page->video->$videoID;

 

There are hundreds of youtube video fields  entered with TextformatterVideoEmbed module . And i can not get these url with 

Quote

echo $page->video;

because it embed iframe and shows youtube video not the url

If i can grab video url i can get the id from there.

I want to keep working this way but i need this url or video id for use on amp-youtube tag

Videos not showing up.:'(

PW Version: 3.0.57

TextformatterVideoEmbed Version: 1.1.1

The module is installed. I have added the "Video embed for YouTube/Vimeo" Text formatter to the body field. I put a link with the format "https://www.youtube.com/watch?v=xxxxxx" into the body surrounded by <p></p> tags. However, when I view the site, I just see the text for the link.

What am I missing?

Thanks!

Make sure your link added as plain text not as clickable link. Also try chaning the order of the text formatters. "Video embed for YouTube/Vimeo" should be on top.

@PWaddict: Thanks. The link is plain text and "Video embed..." is the first text formatter. I tried removing the Hanna Code textformatter to see if it was causing a conflict but it still did not work.

Is the field textarea? Is the Inputfield Type: CKEditor?

      WHY?
      This module was built to fill the gap between simple $pages->find() operations and complex SQL queries.
      The problem with $pages->find() is that it loads all pages into memory and that can be a problem when querying multiple thousands of pages. Even $pages->findMany() loads all pages into memory and therefore is a lot slower than regular SQL.
      The problem with SQL on the other hand is, that the queries are quite complex to build. All fields are separate tables, some repeatable fields use multiple rows for their content that belong to only one single page, you always need to check for the page status (which is not necessary on regular find() operations and therefore nobody is used to that).
      In short: It is far too much work to efficiently and easily get an array of data based on PW pages and fields and I need that a lot for my RockGrid module to build all kinds of tabular data.

      Basic Usage

      Hello for all,
      ConfigurationForm fieldtype module is one my experiment from 2016.
      Main target to build this module was to store multiple setup and configuration values in just 1 field and avoid to use 1 db table to store just single "number of items on page", or another db table to store "layout type" etc. Thanks to JSON formatted storage this module can help you to reduce number of PW native fields in project, save DB space, and reduce number of queries at front-end.
      Install and setup:
      Download (at the bottom ), unzip and install like any other PW module (site/modules/...). Create some filed using this type of field (ConfigurationForm Fieldtype) Go to field setup Input tab and drag some subfields to container area (demo). Set "Name" and other params for subfields Save and place field to templates ("Action tab") How to use it:
      In my case, I use it to store setup and configurations values, but also for contact details, small content blocks... (eg. "widgets").
      Basic usage example:
      ConfigForm fieldtype "setup" has subfields:
      "limit", type select, option values: 5, 10, 15, 20
      "sort", type select, option values: "-date", "date",  "-sort", "sort"
      // get page children (items) $limit = isset($page->setup->limit) ? $page->setup->limit : 10; $sort = isset($page->setup->sort) ? $page->setup->sort : '-sort'; $items = $page->children("limit=$limit, sort=$sort");  
      Screenshots:


       
      Notes:
      Provide option to search inside subfields Provide multilanguage inputs for text and textarea field types Provide option for different field layout per-template basis Do not place/use field type "Button" or "File input" because it won't works. Please read README file for more details and examples Module use JSON format to store values. Text and textarea field types are multilanguage compatible, but please note that main target for this module was to store setup values and small content blocks and save DB space. Search part inside JSON is still a relatively new in MySQL (>=5.77) and that's on you how and for what to use this module.
      Thanks:
      Initial point for this fieldtype was jQuery plugin FormBuiled and thanks to Kevin Chappel for this plugin.
      In field type "link" I use javascript part from @marcostoll module and thanks to him for that part.

      Hi guys I'm relatively new to PW and just finished developing a page for a client. I was able to include all necessary functionality using the core fieldtypes but now I it seems that I need to extend them with a custom one. What I need is a simple button, that copies the absolute url (frontend not PW-backend) of the page which is currently edited to the clipboard. As this feature is only needed inside a specific template, I tend to use a custom fieldtype which provides this feature. I've been looking inside the core modules code (eg. FieldtypeCheckbox.module) but I don't really get the structure of it and how its rendered to the admin page. I also didn't find a lot of tutorials covering custom fieldtypes.
      Maybe some of you could give me some tips on how to write a basic custom fieldtype that renders a button which copies the value of
      page->httpUrl() to the clipboard using JS. Thanks!

      Some of you might have followed the development of this module here: https://processwire.com/talk/topic/15524-previewdiscussion-rockdatatables/ . It is the successor of "RockDataTables" and requires RockFinder to get the data for the grid easily and efficiently. It uses the open source part of agGrid for grid rendering.
       
      WHY?
      ProcessWire is awesome for creating all kinds of custom backend applications, but where it is not so awesome in my opinion is when it comes to listing this data. Of course we have the built in page lister and we have ListerPro, but none of that solutions is capable of properly displaying large amounts of data, for example lists of revenues, aggregations, quick and easy sorts by the user, instant filter and those kind of features. RockGrid to the rescue 😉 
       
      Features/Highlights:
      100k+ rows Instant (client side) filter, search, sort (different sort based on data type, eg "lower/greater than" for numbers, "contains" for strings) extendable via plugins (available plugins at the moment: fullscreen, csv export, reload, batch-processing of data, column sum/statistics, row selection) all the agGrid features (cell renderers, cell styling, pagination, column grouping etc) vanilla javascript, backend and frontend support (though not all plugins are working on the frontend yet and I don't plan to support it as long as I don't need it myself)  
      Limitations:
      While there is an option to retrieve data via AJAX the actual processing of the grid (displaying, filtering, sorting) is done on the client side, meaning that you can get into troubles when handling really large datasets of several thousands of rows. agGrid should be one of the most performant grid options in the world (see the official example page with a 100k row example) and does a lot to prevent problems (such as virtual row rendering), but you should always have this limitation in mind as this is a major difference to the available lister options that do not have this limitation.
      Currently it only supports AdminThemeUikit and I don't plan to support any other admin theme.
