Cyb - Check If Already Posted

Info:
User can check if the same/similar thread already exist when posting new one. Button is shown right after the thread title field in newthread form. When button is clicked then javascript code opens popup window with search results. Entered thread title is used as search query. Additionaly you can choose to search thread titles only or entire posts, to show results as threads or posts, to search current forum only or all. You can also exclude forums in ACP, set default pop-up window dimensions,...

All search permissions (by usergroups, forums) will be applied here too.

Installation:
1. Import XML file (as product): AdminCP > Plugin System > Manage Products > [Add/Import Product]

2. OPTIONAL (for very customized styles - if button not shown):
In newthread template find: <td><input type="text" class="bginput" name="subject" value="$subject" size="40" maxlength="85" tabindex="1" /></td>
Below it add: $cybcheckifposted

To set options go to: AdminCP > vBulletin Options > Cyb - Check If Already Posted
