to install, produces this error:
Warning: Cannot modify header information - headers already sent by (output started at /home/mysite/public_html/plugins/_article_titles.plugin.php:2) in /home/mysite/public_html/skins_adm/_html_header.inc.php on line 405 yabba Jun 18, 2008 11:16
Delete the whitespace before the opening <?php tag ;)

hello ¥åßßå
these are the first lines of _html_header.inc.php.
Delete the whitespace before the second opening <? Php tag.

Don't access this file directly, but install it as a plugin. You can then add a widget to your template. Don't include this file in your template.

Check that file ;)

I removed the whitespace in that file just now.

hello nims
steps taken:
=> _article_titles.plugin.php placed inside the folder 'plugins'.
=> checked if it was in http://mysite/admin.php?blog=10&ctrl=plugins&action=list_available.
=> http://mysite/admin.php?ctrl=plugins&action=install&plugin=article_titles_plugin activated with installation.
and continues the error.
11 yabba Jun 18, 2008 13:05
Copy and paste your plugin code as it is now, from notepad into here ( between [php][/php] tags )
¥
12 nims Jun 18, 2008 13:45
Ok, i editted the first message with using PHP tags. Is it alright now?
13 yabba Jun 18, 2008 14:00
Sorry nims, that was directed at participation, if they still have the error then they still have whitespace in the file
¥
14 nims Jun 18, 2008 14:07
Then I don't understand if my plugin has an error, or that it is correct. I am using it myself, and have not got any problems at all.
15 afwas Jun 18, 2008 14:26
Hi nims & participation,
Participation made a copy/paste error, so he unintendedly entered whitespace (carriage return "Enter" or space) before the first <?php resulting in the error mentioned.
Probably you could make a downloadable zip of the plugin to avoid confusion.
Good luck

hi participation,
This shouldn't give an error. Do use a plain text editor when you save the file.
Good luck

I created the file _article_titles.plugin.php with notepad.
installing the plug, this new error occurs:

Delete any whitespace *after* the closing ?>
20 nims Jun 18, 2008 14:54
I think you shouldn't use notepad, but a texteditor that dashes the CR/LF chars and just uses the linux format.
Ultraedit for example has an option to convert the file to linux format. Also some ftp-clients have the option to upload the file as text. Maybe that can "fix" your problem.

Thanks for the plugin
22 emopoops Jan 27, 2009 19:01
isnt that the same as lates t posts?
23 nims Jan 27, 2009 22:01
Yes it is. But it's a little more simple: it only shows the title list, and the paging numbers.
24 martha Jan 30, 2009 05:16
Well, I tried this plugin--copy & paste into dreamweaver file, nothing but code in first posting this thread.
Got this on attempted installation into plugins:
Parse error: syntax error, unexpected '}' in /home/wordturn/public_html/healthygreenpaint/plugins/_article_titles.plugin.php on line 167Ideas????
25 edb Feb 07, 2009 17:34
This plugin is virtually unusable when someone tries to copy/paste it from these forums. I kinda know what I'm doing with grabbing someone else's code, and I keep getting whitespace that simply doesn't show up here.
nims you really need to make a downloadable .zip of this thing else it will always cause the troubles that both participation and martha have reported.
Also please add a readme.html file so users will know what it will do and what they can do with it. Adding a readme is the crappiest ugliest longest WORST part of writing a plugin, but it really does help your users.
BOTTOM LINE: anyone trying to copy/paste this out of one the forums will have to edit out a space before the very first <?php and after the very last ?>
26 joopsiroop Jul 16, 2011 22:50
I do not agree with that.
I copied he code and pasted it in nano (Linux editor).
My editor wrapped some comment lines, but after repairing the plugin worked at once.
Now I have this widget, I only do not understand how to put it above the content on the main page. In the blog setting I can add the widget to the menus or header etc. but how do I generate a main index page with this?
27 sam2kb Jul 16, 2011 23:21
@joopsiroop
This is a very old thread. You don't need this plugin if you are using b2evolution v3 or 4. Just go to Blog settings > Widgets and add a Post list widget
trying that right now
