PHP

<?php

    $servername = 'mysql.hostinger.in';
    $username = '';
    $password = '';
    $dbname = 'u424351292_icrcm';

    if(isset($_POST['submit']))
    {
        $phone_no = $_POST['phno'];
        $full_name = $_POST['fullname'];
        $location = $_POST['address'];
        $department = $_POST['dept'];
        $description = $_POST['desc'];
    }

        $conn = new mysqli($servername,$username,$password,$dbname);

        if($conn->connect_error)
        {
            die("Connection Failed" . $conn->connect_error);
        }

        $sql = "INSERT INTO new_comp_reg (phno , fullname , address , dept , desc)  VALUES ('$phone_no' , '$full_name' , '$location' , '$department' , '$description')";

        if($conn->query($sql) === TRUE)
        {
            echo "Complaint Registered";
        }
        else
        {
            echo "ERROR".$sql."<br>".$conn->error;
        }

    $conn->close();
    ?>

推荐答案

desc 是一个 MySQL 中的保留关键字，需要用反引号转义.

desc is a reserved keyword in MySQL and needs to be escaped by backticks.

INSERT INTO new_comp_reg (..., `desc`)  VALUES (...)

例如，或者将您的列名更改为 description.

or change your column name to description for instance.

顺便说一句，您没有转义您的用户输入，这可能导致语法错误和 SQL 注入.使用准备好的语句.

BTW you are not escaping your user input which could lead to syntax errors and SQL injections. Use Prepared Statements.
