当放置require而不是代码时结果不同

问题描述 投票:-2回答:1

我有两个文件:signupcontroller和signupmodel:

signupcontroller.php

<?php 
        require "../Models/conn.php";
        $points=0;
        $password=$_POST['password'];
        $password2=$_POST['password2'];
        $phonenb=$_POST["phonenb"];
        require "../Models/signupmodel.php";
?>

signupmodel.php

if ($stmt = $conn->prepare('SELECT  password FROM clients WHERE username = ?'))
 {
    $stmt->bind_param('s', $_POST['username']);
    $stmt->execute();
    $stmt->store_result();
    if ($stmt->num_rows > 0) 
    {
        echo "<script>alert('Username exists');location='../View/signupview.php';</script>";

    } 

    else 
    {
        if ($stmt = $conn->prepare('INSERT INTO clients (username, password, phonenb, nbpoints,  address, name) VALUES (?, ?, ?, ?, ?, ?)')) {

    $stmt->bind_param('sssiss', $_POST['username'], $_POST['password'], $_POST['phonenb'], $points, $_POST['address'],$_POST['fullname']);
    $stmt->execute();
    echo "<script>alert('Signup Successfull!'); location='../View/index.html';</script>";
    }

    }
    $stmt->close();
}
else 
    {
    // Something is wrong with the sql statement, check to make sure accounts table exists with all 3 fields.
    echo 'Could not prepare statement!';
    } 
$conn->close();

[当我将代码从signupmodel复制并粘贴到signupcontroller时,它工作得很好,并且用户注册到了数据库,但是当我将require "../Models/signupmodel.php"并在signupview中输入相同的输入时,它的行为就像是找到并回显该用户名存在,但是没有要求,并且没有将signupmodel中的代码复制到signupcontroller中,它并没有告诉我用户名存在,而是表示用户名成功(这意味着未找到任何行)。我使用的要求是否错误?

php model-view-controller require

[我知道了,我在signupmodel代码之间放置了<?php?>标签,并且它起作用了,现在我不知道为什么,但是如果有人遇到我的问题,请尝试一下。
