168 - Implement Avatar/Gravatars for Joomla! v 1.5

Postby depresz » Wed Jan 09, 2008 5:58 pm

Implement Avatar/Gravatar Support for Joomla! v 1.5 in these ways:

    * Install UserMeta extension and create additional user metadata for:
      +  Gravatar or Avatar preference;
      +  Gravatar URL;
      +  Avatar file;
      +  User-defined preference to display Avatar with articles;
      +  User-defined preference to display Gravatar with comments.
    * Display Gravatar or Avatar with author's article, if preferred.
    * Display Gravatar or Avatar with author's comments, if preferred.

Note: Do not include the UserMeta plugin in the extension package, but
rather provide instructions on how it should be configured for use with
this extension.

Resources:

    * Use Kevin Devine's UserMeta extension (simply provide instructions)
    * Gravatar implementor's guide http://site.gravatar.com/site/implement
    * Use yvComment extension for comments -
http://extensions.joomla.org/component/ ... Itemid,35/


Hmmm... Today I will create plan of project, and, I think tommorow, I'm going to start coding. Will a lot of fun  :laugh:

Tomasz -

Given this and other contributions made by your peers, Joomla! is going to have some seriously cool social networking, blogging and group blogging capabilities. I can't wait to start pulling it all together - then showing off what GHOP has made possible for the Joomla! community.

Thanks for your many contributions!
Amy :)

I am very busy now, because I have a lot of non-Joomla! work (Joomla! works too, but's not so prioritaire).
I know how to do this plugin (from A to Z). I won't need help, so you, Amy, you can feel free in this task ;)
A lot of things depend on calendar_icon plugin which I am developing (few improvements left). BTW: This plugin rlz! I wonder what have I done xD People love it  :)
I think that first version will be ready 15-16 Jan.

Right... after GHOP, Joomla! will be not this same project like before 8)

Thanks,

Here you have list of functions that will be added inside UserMeta & plugin configuration page.
I implemented simpler than in calendar_icon function (simpler = less work and more stable)

Everything is fine ;) Just no problem!

Thanks,

Today good and bad news.

Header avatar done...
Bottom avatar (yvcomment)...

... Houston, we have a problem...

I especially can not connect to the yvcomment. This component doesn't provide some back door, you know, like onPrepareContent function. How can I connect to this component and change some variable from view?
I am a little confused because I am seeking solution second day, without certain results.

What's now?
Need help

Today and dey before I talked with Yuri Volkov and we found solution of my problem. yvcomment will use this same like in com_content event function: onPrepareContent. It will provide more flexibility with writing a code.

I have just resumed work

PROGRESS: 60% 17 Jan

Hi guys!

I've got good news, especially screenshots say everything. Main view:

Image

Other (very important) screen shows overview of selected article (yvcomment avatars). My plugin won't work with yvcomment until new version of Yuri's extension will be released. I felt real spirit of Open Source by talk with Yuri. He's great developer and very open for propositions. It was impossible to create avatars in comments withoutthis  communication. Thanks Yuri for creating flexible platform for me and others programmers.

http://www.depresz.piotrkow.net.pl/ghop ... RTICLE.png

Main scelet of plugin has been just created. Now I'm gonna do following tasks:
*Internationalization (English, Polish and probably German)
*Documentation (very detailed in PDF; because after installation of plugin administrator will have to update User Meta System Plugin's file, I decided to create txt file from which he will just Ctrl+c and Ctrl-c to user meta file. Very simple solution and you'll not loose time by handly re-writing code to file from PDF [I hope you know what I mean xD]).

PROGRESS: 85% 18 Jan

I'll provide code next time.

Oh, maybe I don't know well English, and maybe I don't have great grades in school but I know what Joomla! means. You know, this is not only project. For me it became part of LIFE

You do *excellent* work. Excellent work. So far, you have translated the installation guide into Polish; then, you created a most amazing Twitter Plugin that updates on title post - after getting the URL  and converting it to a tiny url using Curl. Then, you created a blog entry date calendar - which is beautiful. There, you stopped to do THREE unit tests because you knew it was important, given where J! is at. Now, you are building an Avatar/Gravator extension.

Also - your extensions are providing for Kevin Devine's User Extension - and now for Yuri's commenting tool.

I would say you have found something that you are *excellent* at.

Now, school is important so get that done, too, and focus on your work. You are certainly a good match for this type of work and we are so very, very pleased you joined us at Joomla!.

That picture is fabulous. I cannot wait to try your newest extension.

Thanks to Yuri for his work with you and his contributions to Joomla!, as well.

Amy :)

Thank you so much.

Amy: I was starting with (without) nothing. I knew that exist something like Joomla!, but I didn't like (even hate) this CMS! I told bad things about Joomla! without trying this, before. Now, when I understand everything, I can say that I was completly fool. I didn't suppose that I will create so many lines of code, translate entire installation guide, etc. Everytime when I start new thing I feel more experienced. I remember, when I started task with Twitter. I didn't know what the hell is plugin for Joomla! but I took a risk. Many hours with underground coding (nobody knew, even my parents that my 366Mhz machine was running and servers were working xD). I feel proud, what I have done, but other side I feel really, really nasty when I think, that I couldn't help in Joomla! Doc Camp. I hadn't free time, but I declared I will... My honor fell.

You know, Google is power for newbies (me), but... Sure, if I will have some problems, just send PM to you, Johan ;) One more contact xD.

Oh, willebil and MiCCAS, I have something done... but it is not final product yet. You will have to wait for new version of yvcomment also. But now, you can see at this beautiful php signs ;) Plan of parametrs placed on top of this site is a little diffrent from real realization. Oh, I almost forget describe this plugin.


Avatar/Gravatar 1.02 is very flexible, and ready for most (ironic) exception:
* when user will not enter path in UserMeta System Plugin (will be insert default image)
* when user enter path of standar image (e.g. 573x362px, plugin change size to maximum 80x80px size)


Plugin automaticly carry out whether text entried into the Avatar/Gravatar Box is Avatar URL path or Gravatar Username. Now, I can say that user will not finish off installation WITHOUT additional instructions! I know, that's bad, but user has to know, how to enable yvcomment layer that provide avatar space, what enter in UserMeta config file, etc. Installation guide will be very IMPORTANT here.

One of the most important things here is that function getimagesize need more privilages: allow_url_fopen=1.
"Warning: getimagesize() [function.getimagesize]: URL file-access is disabled in the server configuration in".
Plugin is ready to work, even when that's impossible to turn On. I am very preciesly creating every step. I helped yvcomment (other plugins has free way to changing content of yvcomment, now) extension, and yvcomment helped me (special trigger event and generally avatar support).

Every day new version is released (me and Yuri testing it). Again, big thanks for Yuri. HE's doing great work for me. Oh, I just received new e-mail from him ;) Every day I implement brand new thing. Development of this extension is really huge. Only last Saturday and Sunday, totally I intended for Avatar/Gravatar about 20 hours. I have a lot of work with this extension but I love this. If you have any ideas, according code or 'user thinking' things. I think that I will use 200% power for complete this task until GHOP end  :laugh:

I think that I will make an awesome 18 birthday present, finishing this plugin (31 Jan)

PROGRESS: 92% 21 Jan

BTW: Amy, your help is INVALUABLE!

Thankz,
Tomasz

I've downloaded this plugin to test it since I really like the concept of Gravatars and I must say it works really great!

Kudos to you for creating this great plugin. However I have a humble suggestion: Give the avatar/gravatar-image a css-class so that it's easy to style only the (gr)avatar image.

I'm still trying to decide if I like the concept of having to write in your Gravatar-email but everything else is really great.

Great job!

CSS are good. Where have I heared that? ;) I changed type of plugin: Content => System. Now, even in back-end list of comments,avatars are available. Of coure I improved also "preview" method in comments of article (nov avatar available when you press Preview button)

Many things things left to do.

I am so glad that so many people are interested what's going on with my Avatar/Gravatar plugin. I have to represent higest quality of code. I discovered another developer's truth:

Doesn't matter how the code is constructed, and wthat type of function is using. User suppose working product. User don't care when something went wrong. He will just Uninstall plugin. That's why I want to create so high quality product.

I was joking that for my plugin you would carry out unit test  :laugh:

Hi Thomasz,

I just got your PM. I'll put my reply here for everyone to read.

Your question :
I am creating Avatar/Gravatar extension. As you said that you can help me, I'll use your power  ;)  I have following problem: I want to create support for avatars in this same server where is Joomla! I'll give you an example:

I have avatar in path:
http://someserver.com/joomla/images/avatar.png

I want to enter in User's config images/avatar.png, not full path http://someserver.com/joomla/images/avatar.png

Does Joomla! provide some variable that return path to the joomla server? I remember that something was, but didn't work in RC3/RC4 or something like that... can't remember.


There are a few ways to handle this problem :

1. Using JHTML::_('image', $url, $alt, $attribs)

This function adds the root path himself and would be the preferred way of outputting an img element in html. If you use this one it will be something like JHTML::_('image', 'images/avatar.png', 'my avatar', array('class' => 'avatar'));

2. Using JURI::root()

This function will output the root url for the joomla installation, root url being the base url of the site application. You can then use this url to access the images folder.

Hope this helps ?

Cheers,

Johan

Sure, Johan. You helped me  8)

I have created this kind of function manually in Twitter Plugin, but in this extension, implementation won't work. I still don't know what function use. I will have to test both, and check which is better.

Again, thank you Johan. You make that I will not wast precious minutes (or hours - who know?).
After party (school), I'll continue coding.

PROGRESS: 94% 23 Jan // 6:43 p.m. local time

Next time I'll attach new package with many improvements (especially code). Big tribute to Yuri.

Code with many, many (coding) improvements available. This is not final version. It's for testing only.

New development version 1.06 available.

Fixed many bug, especially:
  • preview event check on guest click
  • advanced css styling enable/disable
  • new line on frontpage
  • better behavior on front-end and back-end
  • added default values to variables from system & user config
  • new default size of avatar (after installation without configuration) [better look]
  • some PHP4 improvement
  • ...and many little programming things.

Would be great if this plugin will be worked in PHP4 without any warning. Unfortunetly, I don't have access to PHP4 (localhost, and inet server). I am working with PHP5. It's not so important but would be great.

PROGRESS of plugin: 98%
PROGRESS of doc: 0%

First of all, I'd like to thank you for your effort. This is a great plugin.

I got a little problem tho (it might be my setup)

When I click on the PDF icon, i get this error:

Code: Select all

TCPDF error: Unsupported image type: php?gravatar_id=9505423dda2c2797ee05425a47b0258d&size=55


Could you tell me whether its my setup, or a code error?

Thanks in advance,

Umit.

I have similiar problem. I don't know yet, but I think it's my fault.

I have another big problem. I talked with Yuri about CSS styles, and...

Everything would be OK with styles, but there is problem with rendering site, when my plugin is ative. On first sight, looks OK, but go inside source of page. There is no flexibility in my code (look: "
" doesn't have closing
in right place!!!!!. I could't fix this bug but fortunetly, somehow it works. There are only problems with Firefox, when you first time open site with my plugin enabled (Seems like content page is fragmented: on left side: news, on right side: blank). Every next time while you refresh site, everything is OK: it's something like just: "Oh, I understand that I did something wrong, and I have to render site in diffrent way." (words of web browser). Look at the attachment to this message. I can't support such a big flexibilty with CSS because my plugin is very static. Reason of this problem is small flexibilty of onPrepareContent parameters. I mean, not every element of code is ready to write: (for example I can attach datas to following var:
$row->text = ''.$row->text;


but I can't attach this same code to title variable:
$row->title = ''.$row->title;)


Designing my code I knew that in the future will be problems like CSS, but I had to keep on going. There was no other soultion to working this code. I wanted to avoid solution from "Calendar Icon Plugin" because there, every var, was controlled partial by me and system (I can see that was very, very bad, and I'm trying to use Avatar/Gravatar method, but without results).
Look at core of Joomla component. There is no "block code" (every parameter begin or end HTML code in diffrent place). That's why I don't want to give users excessive access. OK, I understand templates, etc, but look at code of plugin.

Code: Select all

<table style="width:100%; float:right;" cols=1><tr width="100%"><td colspan=2 ><img src="'.$url;

float is right. I wanted to fight with rendering problems, so I thinked out bla, bla, bla: cols=1, colspan=2, but without any success.

Now I am at exit point: Problem is very BIG because I am depend on table, which is float:right. If not: is problem in Internet Explorer. I have to delete somehow and
from my plugin, and insert only . This case is very important because make me stop thinking about everything.

I think that somebody understand me and help with creating my extension. I just want to delete
from my code of plugin. I tried with HTML style tricks, but without effects. I need very flexible trick to work with Firefox, Internet Explorer, Safari and Opera.

Please, people with experience, help me


Tags , ... seems OK in my code. So what's going on with Firefox? If someone had this same situation like from attachment, please write circumstance of situation. (did you first time open site?, server type, version of Fox, etc...).

Tomasz aka depresz already knows my view, but I still want to put it here, and in more detail, for others to discuss.

I think, that content plugin shouldn't try to do more, than it is devised to do (by Joomla! core team): It may change content, but it may not change design of the page (design is done by template AFTER content plugin have executed).
I mean, that this is template work to put avatar to the right place of the page.

So, let's turn to avatar-gravatar plugin: 'original' templates of Joomla! are part of Joomla! core and (preferably) shouldn't be changed. So, maybe we should take this for granted and write some instruction for user: "How you should change your template to see avatars in your articles".

We already have a good example, how this may be done: see the code, that integrates avatar-gravatar plugin with yvComment:
1. yvComment fires the same "onPrepareContent" event
2. avatar-gravatar builds img tag and puts it in the new, special attribute of the $article object: $article->avatar - this attribute is not persisted in database, but it is used for information exchange between components only.
3. Template of yvComment's MVC code (
  components/com_yvcomment/views/comment/tmpl/default.php or
  components/com_yvcomment/views/list/tmpl/default.php,
  -depending on current view of yvComment (that is not the same, as article's view...))
sees this new attribute and inserts it in the right place of the page. Moreover, if some user of yvComment would decide to customize yvComment's template (and will create custom template, e.g. 'templates/mytemplatename/html/com_yvcomment/comment/default.php'), he (or she) may decide to put that avatar of comment to other place,
without patching anything (not Joomla! core, not yvComment, not avatar-gravatar).

So, my proposal is to use for Articles (i.e. for com_content component) the same approach, as is successfully implemented for yvComment: return avatar's img tag to the 'avatar's aware' template though $article->avatar attribute  ???
