ExpressionEngine用户组模块的搜索功能

Posted 2021-02-26

This is a simple search function for the [User Groups](http://www.dabbledoo.com/design/docs/User-Groups-Module/) module for ExpressionEngine. It searches groups (names and descriptions) as well as topics and topic replies. It respects group types as well - results from private groups will not show up in the topic or topic replies search results.

"groups/search.php" is below - it relies on the search form at the very top.

<form id="group_search" method="post" action="{homepage}/groups/search/">
<input type="text" id="group_search_box" name="group_search_box" />
<input type="hidden" id="member_id" name="member_id" value="{member_id}" />
 
<input type="radio" name="search" value="search_discussions" id="search_discussions" checked>Discussions
<input type="radio" name="search" value="search_groups" id="search_groups"> Groups<br>
<input type="submit" value="Submit"/>
</form>
