MYSQL没有从PHP接收数据 [英] MYSQL not receiving data from PHP

问题描述

我试图从输入发送数据到我的sqldata基地。这里是它试图发送信息到数据库的编码。它不会出现在数据库中;

I am trying to send data from input to a my sqldata base. Here is the coding for it trying to send the information to the database. It doesn't appear in the database; what is wrong with the coding?

    <?php
$con=mysqli_connect(/*hostname*/"localhost",
                    /*username*/"user",
                    /*password*/"pass",
                    /*database name*/"dbase");

// Check connection
if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$a =  mysqli_real_escape_string($con, $_POST['a']);
$b =  mysqli_real_escape_string($con, $_POST['b']);
$c =  mysqli_real_escape_string($con, $_POST['b']);
$d =  mysqli_real_escape_string($con, $_POST['d']);
$e =  mysqli_real_escape_string($con, $_POST['e']);
$f =  mysqli_real_escape_string($con, $_POST['f']);
$g = 10 + ($e - $f);

mysql_query("INSERT INTO 'mensscore', (Name, Club, Level, App, Score);
    VALUES ('".$a."',
            '".$b."',
            '".$c."',
            '".$d."'
            '".$g."')");
    ?>

推荐答案

您正在混合mysql和mysqli。更改：

You are mixing mysql and mysqli. Change:

mysql_query("INSERT INTO 'mensscore', (Name, Club, Level, App, Score);
    VALUES ('".$a."',
            '".$b."',
            '".$c."',
            '".$d."'
            '".$g."')");

To：

mysqli_query($con, "INSERT INTO `mensscore` (Name, Club, Level, App, Score)
    VALUES ('$a',
            '$b',
            '$c',
            '$d',
            '$g'
    );");

另请参阅和 PHP：mysqli_stmt - 手动，因为使用POST并不总是安全的，因为人们可以做SQL注入。
