Question

我收到此错误：

警告：mysql_fetch_array（）要求参数1为资源，第9行的？/config.php中给出布尔值

代码：

<!-- Config.php Code -->
    <?php session_start();

    //mysql connection
    $con = mysql_connect("localhost","digmoorc","community20");
    mysql_select_db("digmoorc_EHUB",$con);

    function getUserData($userID) {
        $query=mysql_query("select 'userID' from tbl_users where userID=$userID limit 1");
    while($row = mysql_fetch_array($query))
    if ($query === false) mysql_error();
    {
    }
    }
    ?>

Answer 1

在这种情况下，您必须在行尾找到缺少的分号，并且缺少右括号。

在这种情况下，你的第一个if子句

if(isset($_POST['Submit'])) {

未关闭。所以没有关闭}。

Answer 2

试试这个

<?php

    require("config.php");
$error = '';
    if(isset($_POST['Submit'])) {

        $userName=$_POST['userName'];
        $passWord=$_POST['passWord'];

        $query=mysql_query("select user ID from tbl_users where userName='$userName' and passWord='$passWord' limit 1");
    if(mysql_num_rows($query)==1) {
    //login success
    $data=mysql_fetch_array($query,1);
    $_SESSION['userID']=$data['userID'];
    header("location:dashboard.php");
    exit();

    }else{
    //login failed
    $error="Invalid Login";
    }
}

    ?>
