我想将我的PhpMyAdmin记录添加到自动完成函数中，当有人键入名称或其他内容时，它将在数据库中显示要选择的值。必须在“我的输入”字段中的值来自表地址\u状态

我的代码：

<?php
if(isset($_POST['search']))
{
$valueToSearch = $_POST['valueToSearch'];
// search in all table columns
// using concat mysql function
$query = "SELECT person_id, person_firstname, person_lastname, 
             person_email, person_phonenumber,  
             address_street,address_housenumber, 
             address_city,address_state,address_zipcode,cv_path
      FROM person 
        inner join address on address.address_id = person.person_address 
        inner join cv on cv.cv_id = person.person_cv 
          WHERE CONCAT(`person_firstname`, `person_lastname`, `address_street`, `address_housenumber`, `address_zipcode`, `address_city`, `address_state`, `person_email`, `person_phonenumber` ) 
          LIKE '%".$valueToSearch."%'";

$search_result = filterTable($query);

}
else {
$query = "SELECT person_id, person_firstname, person_lastname,

您是否显示了getuser.php
code？首先，您将不受信任的数据放入SQL查询中，这样在尝试之前我就可以担心您的结构了it@RiggsFolly我将getuser.php添加到同一页面中。当我填写任何信息时，排序是有效的，它只会显示具有该信息的人。但是我只想有一个下拉列表或自动完成，它只显示我可以搜索的信息。。。就像现在我键入示例：Ro时，它将按我的姓名和城市进行检查，因为这也以Ro开头。。。一个包含地址表中的值的下拉列表将是完美的。。。但是自动完成就足够了
