Question

我是网络开发的新手。尝试创建一个登录页面，该页面处理用户信息并在同一页面上抛出错误，而不是重定向到error.php。页面刷新但未提交任何消息。这是代码。

<?php
//check if form has been submitted
if(isset($_POST['submit'])) {

//check if the variables are null
if (empty($user) || empty($password) || empty($domain)) {
    $msg = "<p>Username, Password and Domain cannot be blank</p>";
} else {
    //sanitize the data
    $user = htmlspecialchars (stripslashes (trim ($_POST['user'])));
    $password = htmlspecialchars (stripslashes (trim ($_POST['password'])));
    $domain = htmlspecialchars (stripslashes (trim ($_POST['domain'])));

    //access group variables
    $sausers = "user accounts not member of below groups which need admin access";
    $sagroup = "user group which needs admin access";
    $agroup = "user group which needs user access";
    //$accesslevel = 0;

    //assign LDAP variables based on user domain
    if ($domain == "domain"){
        $ldap_host = "childdomain.domain.com";
        $ldap_user = $user."@childdomain.domain.com";
        $ldap_dn = "DC=childdomain,DC=domain,DC=com";
    }

    //Connect to LDAP Directory
    $ldap = ldap_connect($ldap_host);
    ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION,3);
    ldap_set_option($ldap, LDAP_OPT_REFERRALS,0);
    If ($bind = @ldap_bind($ldap,$ldap_user,$password)) {

        //authentication against AD successful
        $filter = "(sAMAccountName=".$user.")";
        $attr = array("memberof");
        if ($result = ldap_search($ldap, $ldap_dn, $filter, $attr)) {
            $groups = ldap_get_entries($ldap, $result);
            ldap_unbind($ldap);

            //check if user is listed in $sausers
            If(strops($sausers, $user) != false) {
                //access granted - ideally redirect to admin page
                $msg = "<p>Welcome Super Admin</p>";
            }
            //check if user is member of admin team
            foreach($groups[0]['memberof'] as $group) {

                // check if user is a member of admin team
                if(strpos($group, $sagroup) != false) {
                    //access granted - ideally redirect to admin page
                    $msg = "<p>Welcome Super Admin</p>";
                } elseif (strpos($group, $agroup) != false) {
                   //access granted - ideally redirect to admin page
                    $msg = "<p>Welcome user</p>";
                }
            }
        } else {
            //Unable to search LDAP server
            ldap_unbind($ldap);
            $msg = "<p>We are facing issues with LDAP search at this time. Please report this issue to us by emailing emailaddress</p>";
        }
    } else {
        //AD authentication failed
        $msg = "<p>Domain Authentication Failed!!! Please try again.</p>";
    }
}
   }
?>

</div>
<div class="error">

页面将刷新并重置表单，但不会显示任何消息。

Answer 1

你忘了在这里重新打开php标签：

<div class="error">
    <?print "<p>.$msg.</p>";?>
</div>

应该是：

<div class="error">
    <?php print "<p>.$msg.</p>";?>
</div>

同一页面上的表单处理不会显示结果
