Question

我有一个自动填充表单，从表中拉出第一个名字。但是我想使用2个字段自动完成。这两个字段是NAME和LAST_NAME，它们是数据库中的2个单独字段。这是我的搜索代码：

<?php
include('db_connection.php');
if(isset($_POST['search_keyword']))
{
    $search_keyword = $dbConnection->real_escape_string($_POST['search_keyword']);
    $sqlUsers="SELECT ID, NAME, LAST_NAME FROM b_user WHERE NAME LIKE '%$search_keyword%'";
    $resUsers=$dbConnection->query($sqlUsers);

    if($resUsers === false) {
        trigger_error('Error: ' . $dbConnection->error, E_USER_ERROR);
    }else{
        $rows_returned = $resUsers->num_rows;
    }

$bold_search_keyword = '<strong>'.$search_keyword.'</strong>';
if($rows_returned > 0){
        while($rowUsers = $resUsers->fetch_assoc()) 
        { 
            echo '<div class="show" align="left"><span class="user_name">'.str_ireplace($search_keyword,$bold_search_keyword,$rowUsers['NAME']).'</span></div>'; 
        }
    }else{
        echo '<div class="show" align="left">No matching records.</div>'; 
    }
} 
?>

以上代码会在下拉列表中返回第一个名称，但我需要它来搜索NAME，然后继续访问LAST_NAME。有没有办法加入NAME和LAST_NAME。我试过这个：

 $sqlUsers="SELECT ID, CONCAT(NAME, ' ', LAST_NAME) AS FULLNAME FROM b_user WHERE FULLNAME LIKE '%$search_keyword%'";

然后显示：

 <span class="user_name">'.str_ireplace($search_keyword,$bold_search_keyword,$rowUsers['FULLNAME']).'</span>

但这似乎彻底打破了搜索。我觉得我与上述并不遥远，但还没有快乐。感谢您的帮助。

您可以在查询中将NAME和LAST_NAME分开，这样可以更好地控制如何输出自动填充的结果。您只需要更改查询的WHERE子句以查找姓氏上的匹配项。我认为自动完成通常非常松散匹配，这可能会有效。
