我正在开发一个项目，该项目有一个搜索字段，用于搜索和显示单个输入字段中的数据。但我想创建多个输入搜索字段，如：
名称： 地址： 联系： [搜索按钮]
如果用户只填写1个字段，则应显示匹配结果，但如果填充2字段同时包含名称和地址，则应显示与这两个字段匹配的结果，如果填充所有字段，则应显示。我当前的脚本可以正常搜索一个搜索框，但我遇到问题，使其成为一个多搜索框搜索脚本。
这是我搜索数据的index.php。

如何进行多输入字段搜索。
答案 0 :(得分：2)
//在你的SQL查询中
$ search_address = $ _ POST ['searchAddress'];
$ sql =“选择contact_id，CONCAT（first_name，''，last_name）为 联系人姓名， contact_no，residential_address， 公司，company_address来自tblcontact 其中CONCAT（first_name，''，Last_name）喜欢'％$ search％'和 residential_address = '％$ SEARCH_ADDRESS％'“;
答案 1 :(得分：0)
SELECT * FROM tableName WHERE (field1 = 'searchBox1Value' OR field1 = 'searchBox2Value');
答案 2 :(得分：0)
$where = "";
if($search1 != '')
{
$where = "CONCAT(first_name, ' ', Last_name) like '%$search1%'";
}
if($search2 != '')
{
$where += "or residential_address like '%$search2%'";
}
$sql = "select * from tblcontact where ".$where."";
