我是php编程的新手，在尝试创建一个登录php脚本以将其与我的mysql数据库连接时遇到了很多麻烦（我已经创建了一个数据库）
我收到错误：
我的数据库内容是：
Id_Enseignant
Nom_Enseignant
Prenom_Enseignant
mail_enseignant
Mot_de_passe 14 hh hhs hhss
这是我的php脚本：
警告：mysql_num_rows（）要求参数1为resource，布尔值在第16行的C:''examplep''htdocs''University''login.php 中给定
第16行是这一行：
if(mysql_num_rows($sql) == 1){
再加上它在提交按钮旁边显示的内容："; } ?>
<?php
require_once('init.php');
include_once("scripts/connect.php");
$login_error = "";
$email = "";
$password= "";
if(isset($_GET['login'])){
$email = strip_tags(mysql_real_escape_string($_POST['email']));
$password = strip_tags(mysql_real_escape_string($_POST['password']));
$sql = mysql_query("SELECT mail_enseignant,Nom_Enseignant,Mot_de_passe FROM enseignant WHERE email='".$email."' AND password='".$password."' LIMIT 1");
if(mysql_num_rows($sql) == 1){
$row = mysql_fetch_asooc($sql);
$_SESSION['mail_enseignant'] = $row['mail_enseignant'];
$_SESSION['Nom_Enseignant'] = $row['Nom_Enseignant'];
$_SESSION['Mot_de_passe'] = $row['Mot_de_passe'];
header("Location: index.php");
exit();
} else {
$login_error="invalid Information...";
}
}
?>

对于初学者来说，重写这一行（您漏掉了一个括号）：
<?phpif (isset($login_error) && ($login_error != ""){
作为：
<?php if (isset($login_error) && ($login_error != "")) {
此外，更改：
$row = mysql_fetch_asooc($sql);
至：
$row = mysql_fetch_assoc($sql);
此外，字体已弃用。。。尝试p或h1等。
