html+php提交表单插入mysql失败

Question

这是我第一次尝试 PHP，但运气不佳。

数据库是在 phpmyadmin 中创建的，需要的表以相同的顺序 我正在运行 Ubuntu 14.04.1 LTS 5.5.49-MariaDB-1ubuntu0.14.04.1 (Ubuntu) PHP 5.5.9-1ubuntu4.19 (cli)

试试这个：

 $servername = "localhost";  //host name

 $username = "username"; //username

 $password = "password"; //password

 $database = "dbname"; //database name

//mysqli prepared statement 

$conn = mysqli_connect($servername, $username, $password) or die("Connection failed: " . mysqli_connect_error());

mysqli_select_db($conn,$database) or die("Opps some thing went wrong");
$Wn8overall = mysqli_real_escape_string($_POST['wn8overall']);
$Wn8recent = mysqli_real_escape_string($_POST['wn8recent']);
$Email = mysqli_real_escape_string($_POST['email']);
$Zileonline = mysqli_real_escape_string($_POST['zileonline']);
$Tara = mysqli_real_escape_string($_POST['tara']);
$Tank10 = mysqli_real_escape_string($_POST['tank10']);
$Tank8 = mysqli_real_escape_string($_POST['tank8]);
$Careclan = mysqli_real_escape_string($_POST['careclan']);
$Numecont = mysqli_real_escape_string($_POST['numecont']);

$stmt = $conn->prepare("INSERT INTO aplicatii1 (wn8overall,wn8recent,email,zileonline,tara,tank10,tank8,careclan,numecont)  VALUES (?,?,?,?,?,?,?,?,?)");

$stmt->bind_param('sssssssss',$Wn8overall,$Wn8recent,$Email,$Zileonline,$Tara,$Tank10,$Tank8,$Careclan$Numecont);
            /*
                The argument may be one of four types:

                            i - integer
                            d - double
                            s - string
                            b - BLOB
                            change it by respectively
            */ 
$stmt->execute();

$row_count= $stmt->affected_rows;

$stmt->close();
$conn->close();

 if($row_count>0){
    echo "New record created successfully";
 }
else{

}

Answer 2

根据您的编码标准，错误在于以下语句，即当您提交变量时，提交按钮应具有相应的名称以及插入语句，并使用引号和反引号。 You have not closed the form as per the Question you have provided

aplicatie.php

<?php

$username = "root";
$password = "pass";
$db = "aplicatii";
$con = new mysqli($host,$username,$password,$db);
if (mysqli_connect_errno())
{
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
echo "Connected successfully";
if(isset($_POST['save_form']))// Here the form method will executed if it is Submitted
{
$prepare="INSERT INTO `aplicatii1` (`wn8overall`,`wn8recent`,`email`,`zileonline`,`tara`,`tank10`,`tank8`,`careclan`,`numecont`) VALUES ('".$_POST['wn8overall']."','".$_POST['wn8recent']."','".$_POST['email']."','".$_POST['zileonline']."','".$_POST['tara']."','".$_POST['tank10']."','".$_POST['tank8']."','".$_POST['careclan']."','".$_POST['numecont']."'')";
$results = $con->prepare($prepare);// Prepare the Statements Here
$results->execute();// Execute the Statement Here
$results->close();// Close the Executed Statement Here
}
?>

根据mysqli.* 的新标准，单独使用参数化语句更好也更可取。但是根据您不打算在线运行的建议，您可以使用此方法并希望它能破解您的错误。分享一下这段代码执行后的想法。
