Tweet this post

Following on from my "Tweet this topic" snippet, I thought I would carry on an release the "Tweet this post" snippet. I think you'll be able to guess what this does Uses almost the same code as the other snippet.

Again, for a demo check these forums. I have it here ^_^
demo removed for performance reasons

OPEN: viewtopic.php
FIND:

Code: Select all

        $s_first_unread = $first_unread = true;
    } 

Code: Select all


    // Tweet This Post
    $hashtag        = ' #phpBB #6StringMODs'; 

Comment:
Feel free to change your hashtags to whatever your feel like - your own sitename perhaps. It would also be nice to tweet this topic/post/page via your won account

Code: Select all

        'S_HAS_ATTACHMENTS'    => (!empty($attachments[$row['post_id']])) ? true : false, 

BEFORE ADD:

Code: Select all

        'TWEET_POST'        => urlencode('Read This: ') . generate_board_url() . "/viewtopic.$phpEx?f=$forum_id%26t=$topic_id%23p{$row['post_id']}" . htmlspecialchars(urlencode($hashtag)), 

OPEN: language/en/viewtopic.php

If you have already installed "Tweet this topic", then you can skip the next 2 steps and go straight to purging your cache

OPEN: styles/prosilver/theme/colours.css
FIND:

Code: Select all

a.right:hover {
   color: #5E7BAA;
}

AFTER ADD:

Code: Select all

.tweet-link a {
   float: left;
   background-image: url("{T_THEME_PATH}/images/twitter-logo.png");
   padding-left:18px;
   height: 18px;
   background-repeat: no-repeat;
   position: absolute;
}

ps. I'm still working on the CSS issues with IE

IE / other browser bugs fixed, thanks to Raimon's post here
Code in 1st post updated

Tweet this page
Using the same logic, you can add the TinyURL() function to this MOD

[kenny]

Had a little request for this addition, which you can easily modify to your needs.
Basically it allows you add some of the post itself to the tweet

Replace

Code: Select all

        'TWEET_POST'        => urlencode("{$row['post_subject']}: ") . truncate_string($row['post_text'], 60, 255, true, '...') . generate_board_url() . "/viewtopic.$phpEx?f=$forum_id%26t=$topic_id%23p{$row['post_id']}", 

I added the phpbb truncate_string() function.
A little info on the params for those who aren't sure:

Code: Select all

truncate_string($string, $max_length = 60, $max_store_length = 255, $allow_reply = true, $append = '') 

Truncates string while retaining special characters if going over the max length
The default max length is 60 at the moment
The maximum storage length is there to fit the string within the given length. The string may be further truncated due to html entities.
For example: string given is 'a "quote"' (length: 9), would be a stored as 'a "quote"' (length: 19)

param: string $string The text to truncate to the given length. String is specialchared.
param: int $max_length Maximum length of string (multibyte character count as 1 char / Html entity count as 1 char)
param: int $max_store_length Maximum character length of string (multibyte character count as 1 char / Html entity count as entity chars).
param: bool $allow_reply Allow Re: in front of string
param: string $append String to be appended[/code]

I have found a small bug in this snippet. I will attempt to fix it, but this might not come for a few days. Basically, if you have any kind of BBCode in the 1st few characters of the post, it will break the tweet. An example can be found in this post
The URL ends up as:

http://twitter.com/home?status=Last+Post+Subject+w%2F+Trim%3A+@[url=http
://twitter.com/13thoughts:182izk6j]13th...http://tinyurl.com/o9eyf9

Smilies would also break this. If anyone can post a fix before I can, please feel free to do so. It will be very much appreciated. I will do my best to try and resolve this though

[kenny]

Thanks to [phpbb]Erik Frèrejean[/phpbb] from the phpBB Support Team, I have managed to find a fix for the issue. I stripped out the bbcode from the text that was being sent to the tweet. phpBB has a built in function for stripping bbcode, but it doesn't return the text, so I duplicated it and made it return. Maybe not the best way to do it, but it works.

Here is the fix:

If you haven't already, definitely think about implementing the TinyURL function into this snippet. It will at least save you a few characters in your tweet

[kenny]

Fixed a small bug in the implementation of the hashtag.
You can find the fix here - bugs.php?p=1&t=11

[rdean]

It doesn't look like urlencode is being passed to the html body ...

The code results like this --

Code: Select all

span class="tweet-link"><a href="http://twitter.com/home?status=" class="tweet-link" title="Tweet this post"></a></span></h3>

I've attached a screen shot of what I'm talking about .. can you assist?

[kenny]

Hi, can you post me the code that you added into viewtopic.php. It's working fine on my site (although I have some custom modifications made to it). It may be a simple typo on your or even my own part

[rdean]

Sure -- here's what I have in viewtopic

Code: Select all

   $s_first_unread = false;
   if (!$first_unread && $post_unread)
   {
      $s_first_unread = $first_unread = true;
   }


    // Tweet This Post
    $clean_text     = stripr_bbcode($row['post_text'], $row['bbcode_uid']);
    $hashtag        = " #phpBB #SurvivalOnlineUS";

   //
   $postrow = array(
      'POST_AUTHOR_FULL'      => get_username_string('full', $poster_id, $row['username'], $row['user_colour'], $row['post_username']),
      'POST_AUTHOR_COLOUR'   => get_username_string('colour', $poster_id, $row['username'], $row['user_colour'], $row['post_username']),
      'POST_AUTHOR'         => get_username_string('username', $poster_id, $row['username'], $row['user_colour'], $row['post_username']),
      'U_POST_AUTHOR'         => get_username_string('profile', $poster_id, $row['username'], $row['user_colour'], $row['post_username']),

   

Code: Select all

      'TWEET_POST'      => urlencode("{$row['post_subject']}: ") . truncate_string($clean_text, 60, 255, true, ' ...') . TinyURL(generate_board_url() . "/viewtopic.$phpEx?f=$forum_id%26t=$topic_id%23p{$row['post_id']}") . htmlspecialchars(urlencode($hashtag)),
