我想知道是否有人可以帮助我。
我正在尝试整合功能，允许管理员使用电子邮件地址作为搜索条件在mySQL数据库中搜索用户详细信息。搜索完成后，我希望我的表单中的“第一个”和“姓氏”字段可以在检索到的记录中完成。
我认为搜索在表单刷新时有效，但它不会检索任何可见信息。
我只是想知道是否有可能请有人可以查看下面的代码，让我知道我哪里出错了。
非常感谢

答案 0 :(得分：1)
您是否错过了针对查询实际运行mysql_fetch_assoc函数的步骤？仅将mysql_query的结果分配给变量$result是不够的！
在致电mysql_query后添加以下内容：
if($result)
{
$row = mysql_fetch_assoc($result));
}
答案 1 :(得分：1)
要获得查询产生的所有行，您需要使用mysql fetch函数（有几个）。
preffered方法绝对是mysql_fetch_assoc
代码的相关部分如下所示：
$email = mysql_real_escape_string($_POST['email']); // make the value safe for in the query
$result = mysql_query("SELECT * FROM userdetails WHERE emailaddress like '%$email%'");
$rows = array();
while ($row = mysql_fetch_assoc($result)) {
$rows[] = $row;
}
// $rows is now a multi dimensional array with values found by the query
答案 2 :(得分：-2)
简单地回顾一下你的代码，我认为你没有正确地在你的sql查询中传递电子邮件的价值。尝试使用它。
$result = mysql_query("SELECT * FROM userdetails WHERE emailaddress like '%" . $email . "%'");
