我有一个注册表单，我在项目中使用了securimage验证码。当我希望在session_start(); print_r($_post)结果为array()之后回复某事时，但当我评论所有if条件时，为什么？当我将表单提交到此页面时，但是对于这种情况，请不要仅提交页面刷新：
if ($_server request_method == post )//stop here don't go inside if condition
这是我的register.php页码：
<?PHP
session_start();
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
include_once dirname(__FILE__).'/process/dbconfig.php';
$flag=true;
echo"Asb";
if(isset($_POST['captcha_code'])){
include_once dirname(__FILE__) . '/captcha/securimage.php';
$captcha = $_POST['captcha_code'];
$image = new Securimage();
echo $_POST['captcha_code'];
if ($image->check($_POST['captcha_code'] ) == false) {
$flag=false;
$_SESSION['caperr']='Invalid captcha code';
//$err='Invalid captcha code';
header('Location: '.'reister.php');
}
//print_r($_SESSION['caperr']);
if(isset($_POST['firstname']) && isset($_POST['lastname']) && isset($_POST['username']) && isset($_POST['password1'])
&& isset($_POST['password2']) && isset($_POST['day']) && isset($_POST['year']) && isset($_POST['month'])
&& isset($_POST['cell']) && isset($_POST['agree']) && isset($_POST['gen']) && ($_POST['password1']==$_POST['password2']) && $flag && isset($_POST['agree'])){
$conn = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
$sql = $conn->prepare('Insert into users(firstname,lastname,username,password,birthday,gender,phone)values(:firstname,:lastname,:user,:pass,:birth,:gen,:phone)');
$user=$_POST['username'];
$firstname=$_POST['firstname'];
$lastname=$_POST['lastname'];
$pass=md5($_POST['password1']);
$birth=$_POST['day'].'-'.$_POST['month'].'-'.$_POST['year'];
$gen=$_POST['gen'];
$phone=$_POST['cell'];
$sql->bindParam(':user',$user,PDO::PARAM_STR,60);

$sql->bindParam(':phone',$phone,PDO::PARAM_STR,11);
if($sql->execute()){
$_SESSION['success']='Your register is successful! ';
}
}
else{
if(!($_POST['password1']==$_POST['password2'])){
$_SESSION['errsubmitp']='Your passwords must same!';
}
else
$_SESSION['errsubmit']='Please fill all inputs!';
$_SESSION['caperr']='Invalid captcha code';

}
}

}

我看到同样的问题，但任何主题都有我的问题答案。请帮我处理这个问题。
我在var_dump($_SERVER)之前回复if ($_SERVER['REQUEST_METHOD'] == 'post')，这是我的结果：

也许在IF
之前尝试回复你$_SERVER['REQUEST_METHOD']变量
或var_dump($_SERVER)并查看此阵列中的错误 - 也许您的服务器未设置REQUEST_METHOD键
或尝试：
if( count($_POST) ){/*....*/};
答案 1 :(得分：0)
PHP字符串比较区分大小写。由于您有method="post"，因此post中的$_SERVER['REQUEST_METHOD']和POST == post false为php > var_dump('POST' == 'post');
bool(false)
