我为我的表单上传了图片，但这会增加错误的时间

致命错误：未捕获的异常“PDOException”和消息“SQLSTATE [23000]：完整性约束违规：/www/data08/users/i/itsiim.planet.ee/htdocs/ 中的 1048 列“图像”不能为空” progemine/system/lisa.php:58 堆栈跟踪：#0 /www/data08/users/i/itsiim.planet.ee/htdocs/progemine/system/lisa.php(58): PDOStatement->execute(Array) # 1 {main} 在第 58 行的 /www/data08/users/i/itsiim.planet.ee/htdocs/progemine/system/lisa.php 中抛出

文件上传似乎出了点问题。 is_uploaded_file() 和 move_uploaded_file() 检查没有其他分支。

<?php 
require 'conf/db.php';
$errors = array();
if ( !isset($_POST['nimi'],$_POST['email'],$_POST['mobiil'],$_POST['sugu']) ) {
    $errors['parameter'] = 'missing POST parameter';
}
else {
    // keep track post values
    $nimi = $_POST['nimi'];
    $email = $_POST['email'];
    $mobiil = $_POST['mobiil'];
    $sugu = $_POST['sugu'];

    // validate input
    if (empty($nimi)) {
        $errors['nimi']  = 'Palun sisesta nimi';
    }

    if ( !filter_var($email,FILTER_VALIDATE_EMAIL) ) {
        $errors['email'] = 'Palun sisesta korrektne e-mail';
    }

    if (empty($mobiil)) {
        $errors['mobiil'] = 'Palun sisesta mobiili number';
    }

    if (empty($sugu)) {
        $errors['suguError'] = 'Palun vali sugu';
    }

    if ( empty($errors) ) {
        //Pilt
        if( !is_uploaded_file($_FILES['image']['tmp_name']) ) { 
            $errors['upload'] = 'no file uploaded';
        }
        else {
            $folder = "upload/"; 
            $file = basename( $_FILES['image']['name']); 
            $full_path = $folder.$file; 
            if( !move_uploaded_file($_FILES['image']['tmp_name'], $full_path) ) { 
                $errors['upload'] = 'cannot move file';
            }
            else {
                $image = $full_path;
            }
        }
    }
}

// insert data
if ( empty($errors) ) {
    $pdo = Database::connect();
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $sql = "INSERT INTO kliendid (nimi,email,mobiil,sugu,image) values(?, ?, ?, ?, ?)";
    $q = $pdo->prepare($sql);
    $q->execute( array($nimi,$email,$mobiil,$sugu,$image) );
    Database::disconnect();
    header("Location: index.php");
    die;
}
else {
    echo '<pre>', join("\r\n", $errors), '</pre>';
}

【解决方案2】：

问题是因为Undefined index: image，这意味着您的文件没有上传。那是因为您没有在 <form> 元素中设置 enctype="multipart/form-data"。应该是，

<form class="form-horizontal" action="lisa.php" method="post" enctype="multipart/form-data"> 

    // your HTML code

</form>
