我的网站成员(member)区域的“index.php”中出现错误，我遇到了这些错误
Warning: mysql_connect() [function.mysql-connect]: Host 'srv9.000webhost.com' is not allowed to connect to this MySQL server in /home/a8479867/public_html/pages/index.php on line 6
Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in /home/a8479867/public_html/pages/index.php on line 7

Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /home/a8479867/public_html/pages/index.php on line 11
SQL 错误!
SELECT count(*) FROM membre WHERE login="momo1o4" AND pass_md5="b83287a789719ce4a412b0b9da582cee"
Access denied for user 'a8479867'@'localhost' (using password: NO)
这是我的代码
<?php
// on teste si le visiteur a soumis le formulaire de connexion
if (isset($_POST['connexion']) && $_POST['connexion'] == 'Connexion') {
if ((isset($_POST['login']) && !empty($_POST['login'])) && (isset($_POST['pass']) && !empty($_POST['pass']))) {
$base = mysql_connect ('server', 'login', 'password');
mysql_select_db ('nom_base', $base);
// it tests whether a database entry contains the couple login / pass
$sql = 'SELECT count(*) FROM membre WHERE login="'.mysql_escape_string($_POST['login']).'" AND pass_md5="'.mysql_escape_string(md5($_POST['pass'])).'"';
$req = mysql_query($sql) or die('Erreur SQL !<br />'.$sql.'<br />'.mysql_error());
$data = mysql_fetch_array($req);
mysql_free_result($req);
mysql_close();
// if a response is obtained, then the user is a member
if ($data[0] == 1) {
session_start();
$_SESSION['login'] = $_POST['login'];
header('Location: membre.php');
exit();
}
// if there is no response, the visitor was wrong either in his login or password in
elseif ($data[0] == 0) {
$erreur = 'Compte non reconnu.';
}
// if not, then there is a big problem :)
else {
$erreur = 'Probème dans la base de données : plusieurs membres ont les mêmes identifiants de connexion.';
}
}
else {
$erreur = 'Au moins un des champs est vide.';
}
}

最佳答案
您似乎正在尝试使用 ftp 用户名 (a8479867) 连接到 mysql，但我很确定您仍然需要手动将该用户(使用正确的密码)添加到 mysql。
您的虚拟主机面板中应该有一个选项来创建 mysql 用户并更新其密码。
