我想根据复选框选择进行带有或不带有多个类别的 mysqli 全文搜索。

搜索基于同一列中的四个类别。

搜索类别是 Windows、游戏、平板电脑、移动设备。

当通过复选框选择搜索选择类别/多个类别时，应仅对选定类别进行。

表结构

id  category   title                date ...
1   windows    windows7             d1  ...
2   games      windows games        d2  ...
3   tablet     windows tablet       d3  ...
4   mobile     windows mobile       d4  ...
5   windows    windows8             d5  ...
6   windows    windows vista        d6  ...

搜索复选框是

搜索

  <li><label><input name="all" type="checkbox" checked="checked" />All</label></li>
  <li><label><input name="windows" type="checkbox" />Windows OS</label></li>
  <li><label><input name="mobile" type="checkbox" />Windows Mobile</label></li>
  <li><label><input name="games" type="checkbox" />Windows Games</label></li>
  <li><label><input name="tablet" type="checkbox" />Windows Tablet</label></li>

示例 1：

Search for 'windows' should return result as

windows7
windows8 
windows vista

When only checkbox windows is checked

示例 2：

Search for 'windows' should return result as

windows7
windows8 
windows vista
windows games

When checkbox windows and games are checked.

我已经进行了查询，但它根本不起作用。

$query = "SELECT * FROM $table WHERE ";
$query .= "category='' ";
$query .= "OR category='windows' ";
$query .= "OR category='games' ";
$query .= "OR category='mobile' ";
$query .= "OR category='tablet' ";

$query .= " AND MATCH (title) AGAINST ('+$keyword*' IN BOOLEAN MODE) ORDER by id desc, title desc LIMIT 10";

我也尝试过这样但没有工作。

$query = "SELECT * FROM $table WHERE ";
$query .= "MATCH (category) AGAINST ('' IN BOOLEAN MODE) ";
$query .= "OR MATCH (category) AGAINST ('windows' IN BOOLEAN MODE) ";
$query .= "OR MATCH (category) AGAINST ('games' IN BOOLEAN MODE) ";
$query .= "OR MATCH (category) AGAINST ('mobile' IN BOOLEAN MODE) ";
$query .= "OR MATCH (category) AGAINST ('tablet' IN BOOLEAN MODE) ";

$query .= " AND MATCH (title) AGAINST ('+$keyword*' IN BOOLEAN MODE) ORDER by id desc, title desc LIMIT 10";

请查看为什么它不起作用并建议如何针对未选择的字段进行搜索查询。

谢谢。

1 
SELECT * FROM table WHERE MATCH (field1, field2, field3, field4) 
                          AGAINST ('keyword' IN BOOLEAN MODE)

似乎你需要什么。

但是您的查询对 SQL 注入是开放的。

现在可以回答了。所以，这里有一个基于safeMysql的解决方案（因为原始 mysqli 会占用太多代码）

$sql  = "SELECT * FROM ?n WHERE category IN(?a) 
          AND MATCH (title) AGAINST (?s IN BOOLEAN MODE) ORDER by id desc LIMIT 10";
$data = $db->($sql,$table,$_GET['category'], $_GET['keyword']);

请注意，您必须将您的复选框字段称为

<input name="category[]" value="windows" type="checkbox" />
