Adding Facebook "Like" Button

[cozbaldwin2]

I can't seem to figure out how to get the Facebook "Like" button added to each article.
Please take a look at what they provide. We're looking for a way to include the current page's URL into the iframe source:

<iframe src="http://www.facebook.com/plugins/like.php?HTTP://CURRENT_PAGE_URL&layout=standard&show_faces=true&width=450&action=like&font=trebuchet+ms&colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:450px; height:100px"></iframe>

Is this possible? If so, how?

Thanks.

Hi,

you could add this in the template with an additional template variable for the URL in the iFrame. Here's how you can do this: http://faq.phpmyfaq.de/content/11/48/en ... ework.html

Ok. This is a little over my head, but I THINK I understand.
Let's see if I have this straight:

* In the test.php, would my content go between these single-quotes:

Code: Select all

$testContent = '';

?

* And what would my content be, exactly? Something like:

Code: Select all

<?php echo $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; ?>

?

* Then register the variable in config/constants.php maybe called "getUrl" ?

* And then, once I get those two things worked out, my Like Button iFrame code would then look like:

<iframe src="http://www.facebook.com/plugins/like.ph ... heme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:450px; height:100px"></iframe>

This all look right?

Hi,

looks okay.

Nope. The error when clicking the Like button says "The page at http://%7BgetUrl%7D could not be reached." so it's not even getting past that command and its rendering it as text, i guess.

[Thorsten]

Hi,

you forgot the processTemplate() stuff, that's why your template variable {getUrl} isn't rendered.

No, that's all in there. Let me show you what I have: (please note, Instead of "test" i have been using getUrl for everything.)

So when I tried looking at index.php?action=getUrl i saw the php echo $_SERVER thing was being printed and not rendered either. So I started using "<script>document.write(location.href);</script>" in the writeContent. This works when I view the new page.

Still, the Like button is not rendering {getUrl}.

Here's all I have:


getUrl.php (placed in FAQ root):

Code: Select all

<?php

$getUrlTitle = 'Get The URL!';
$getUrlContent = '<script>document.write(location.href);</script>';

for($i=0; $i<10; $i++) {
    $getUrlContent .= 'Line '.$i.'<br />';
}


$tpl->processTemplate ('writeContent', array(
                            'getUrlTitle'     => $getUrlTitle,
                            'getUrlContent'   => $getUrlContent
                            )
                        );
$tpl->includeTemplate('writeContent', 'index');
?>

getUrl.tpl (placed in faq/template/ directory):

Code: Select all

<!-- Start Test Content -->
  <h2>{getUrlTitle}</h2>
    <span>{getUrlContent}</span>
    <!-- End Test Content -->

And in inc/constants.php I now have:

Code: Select all

$allowedVariables = array(
    'add'               => 1,
    'artikel'           => 1,
    'ask'               => 1,
    'contact'           => 1,
    'help'              => 1,
    'instantresponse'   => 1,
    'mailsend2friend'   => 1,
    'news'              => 1,
    'open'              => 1,
    'register'          => 1,
    'save'              => 1,
    'savecomment'       => 1,
    'savequestion'      => 1,
    'savevoting'        => 1,
    'search'            => 1,
    'send2friend'       => 1,
    'sendmail'          => 1,
    'show'              => 1,
    'sitemap'           => 1,
    'thankyou'          => 1,
    'translate'         => 1,
    'writecomment'      => 1,
	'getUrl'      => 1,
);

Now, in your tutorial, you said this should go in "config/constants.php" -- but I'm guessing that was for an older version of phpMyFaq. I only see constants.php in INC directory. Should it be somewhere else?

[Thorsten]

HI,

the link was for the current stable 2.6 version, if your constants.php file is in inc/, then you're using 2.0 or 2.5.

I think you don't need a new file, just a new template variable.

[cozbaldwin2]

Argh, yes - I'm running 2.5.2, sorry.

Could you be a little more specific in what I need to do now, please?

[Thorsten]

Hi,

open template/artikel.tpl and add the following where you like to:

Code: Select all

<iframe src="http://www.facebook.com/plugins/like.php?href={getCurrentUrl}&layout=standard&show_faces=true&width=450&action=like&font=trebuchet+ms&colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:450px; height:100px"></iframe>

Then open artikel.tpl and change the template variable array, look for the line

Code: Select all

    'writeComments'                 => $comment->getComments($record_id, PMF_Comment::COMMENT_TYPE_FAQ)));

and change it to

Code: Select all

    'writeComments'                 => $comment->getComments($record_id, PMF_Comment::COMMENT_TYPE_FAQ),
    'getCurrentUrl'                 => urlencode($facebookUrl)));

Nothing else to do and it works.

This is really annoying, I know. But that did not work.
Facebook has not made this as easy as they could have, I don't believe.

Now when I click on the Like button, it tells me:
"You must specify an URL as part of this widget or API."

If it helps, I was able to get it working in Wordpress by putting "<?php the_permalink() ?>" in the iFrame's query string as the href=.
I tried <?php getCurrentUrl() ?> in hopes that would work... but it didnt.

[Thorsten]

Hi,

how does it look like now in your page? I tested it yesterday and it worked.

bye
Thorsten

[cozbaldwin2]

Well it LOOKS fine. It's always looked fine. But when you actually Click it, the word ERROR appears. Clicking the word Error will launch a pop-up and show you what it's having a problem with. First was the invalid URL. Now it's saying it's not seeing (I have not specified) a URL.

[Thorsten]

Hi,

can I check your code online?
