Question

我正在使用自定义表单帖子，并根据以下代码将数据发送到电子邮件。但是我对DB的insert语句似乎不起作用。而且，我的数据库中名为“lead”的表仍然是空的。我几乎遵循了以下示例：http://www.w3schools.com/php/php_mysql_insert.asp 任何指针都会受到赞赏，以使这个sql插件工作，

<?php
error_reporting(E_ALL);
if($_POST){

$to = 'myemailaddres@example.com';

$subject = 'Website Enquiry';
$now = new DateTime();
$datesent=$now->format('Y-m-d H:i:s'); 

$name = $_POST['name'];
$telephone = $_POST['telephone'];
$email = $_POST['email'];
$comments =  $_POST['comments'];    
$fname =  $_POST['fname'];  

$username = "usertest";
$password = "pwdtest";
$dbname = "dbtest";
$servername = "localhost";


//spam checks

if ( isset($fname) && !isset($fname) ) {
    echo 'spam';
    exit();
} elseif ( preg_match("/http/i","$comments")  ){ 
    echo '<h1>Spam detected</h1><p>Sorry, no urls allowed in comment box.</p>';
    exit(); 
}

$data = clean($_POST);

if(validate($data) == 0){

    $email = $data['email'];
    $headers = "From: ".$data['name']." <".$email.">\r\n".
    "Bcc: <".$bcc.">\r\n".
    "X-Mailer: PHP/" . phpversion();


    if($data['form'] == 'quote') {
        $subject = 'Quick quote - '.$subject; 
    }else if($data['form'] == 'enquiry') {
        $subject = 'Enquiry Form - '.$subject; 
    }else{
        $subject = 'Enquiry Form - '.$subject; 
    }

    foreach ($data as $k => $v) { 
        if($k != "Submit" && $k != "form" && $k != "fname" && $k != "quiz" && $k != "captcha_code"){
            $k = str_replace ( "_" , " " , $k );
            $message .= $k.": ".$v."\n\r"; 
        }
    }

    if(mail($to, $subject, $message, $headers)){

        /****** TEST SEND TO DB ***********/


// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO leads (name, telephone, email, date)
VALUES ($name, $telephone, $email, $datesent)";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();



/********* END TEST SEND TO DB *****/

        header("Location: /thank-you"); 
    } else {
        //echo 'Mail Error';
        header("Location: /error");

    }

}else{
    //echo 'Validate Error';
    header("Location: /error"); 
}

}else{
    //echo 'Post Error';
    header("Location: /error");
}

function clean($post){
    $remove = array('vin');
    $data = array();

    foreach($post as $key => $value){

        if(in_array($value,$remove)){
            $data[$key] = '';
        }else{
            $data[$key] = $value;
        }
    }

    return array_filter($data);
}

function validate($data){
    $error = array();

    if (!preg_match('/^[^\@]+@.*\.[a-z]{2,6}$/i', $data['email'])) {
      //    $error[] = '1';
    }

    if ((strlen($data['name']) < 1) || (strlen($data['name']) > 32)) {
        //$error[] = '1';
    }

    if ((strlen($data['telephone']) < 10)) {
        $error[] = '1';
        echo 'Please enter 10 digit numbers for telephone number';
    }



    if(isset($data['form'])){
        if($data['form'] == 'quote'){
            if ((strlen($data['address']) < 1)) {
                // $error[] = '1';
            }
        }
    }

    return count($error);
}

?>

Answer 1

我假设姓名，电话，电子邮件和日期都是字符串类型，如果是字符串

则加上引号

$sql = "INSERT INTO leads (name, telephone, email, date)
VALUES ('$name', '$telephone', '$email', '$datesent')";

Answer 2

用户在连接php变量和字符串时纠正字符串连接的方法。

$sql = "INSERT INTO leads (name, telephone, email, date)
VALUES ('".$name."', '".$telephone."', '".$email."', '".$datesent."')";

将表单字段插入DB
