Fault in uninstalling a plugin didn't remove the code

[JesusChristIsGod]

Plugin: User CSS
Description: Simple plugin which sticks a Custom CSS textbox under UserCP -> Options.
Site: http://mybbhacks.zingaburga.com/showthread.php?tid=1300

I removed the plugin and the texbox remained in the usercp, and installed it again and it added another textbox, and when I uninstalled is again it removed it but not the original. So there is a stuck textbox there.

Is there is a simple modification to the PHP I could make so that when deactivating and uninstalling it it would remove the extra code?

Thanks.

Yes you could make the modification to the plugin but is removing it from your theme all you're wanting to do? If so just go in and manually delete the template code.

[JesusChristIsGod]

Yes, just wanting to remove it from theme. Thank you. I'll seek the code in the template. ... will you please give me a clue what to search and remove?

[Corey H]

It will be in your usercp_options template under UserCP Templates.

What you should be looking for and removing: it'll be some of the data in this.

find_replace_templatesets('usercp_options', '~(?:\<td colspan\="2"\>\{\$stylelist\}\</td\>|\{\$board_style\})~i', "$0\n</tr>\n<tr>\n<td colspan=\"2\" class=\"smalltext\"><label for=\"usercss\">Custom CSS:</label> [WARNING! save down <a href=\"usercp.php?action=options&amp;nousercss=1\">this link</a> in case you mess up your CSS]</td></tr><tr><td colspan=\"2\"><textarea name=\"usercss\" id=\"usercss\" style=\"width: 100%; height: 4em;\">{\$user['usercss']}</textarea></td>");

Thank you.

Thank you.

That's all it takes. Just a little looking around and you'll start to understand MyBB's templating system fairly quickly.
