标签： php database insert mysqli set

将值插入数据库时​​，我总是遇到错误。但是当我只使用mySQL时，它正在工作，我是SQLi的新手，所以请成为gentel。

insert.php 

    <?php
    include("dbinfo.inc.php");

    //connect to mysql server
    $mysqli = new mysqli("localhost", $username, $password, $database);

    //check if any connection error was encountered
    if(mysqli_connect_errno()) {
        echo "Error: Could not connect to database.";
        exit;
    }     

    //insert    
    $query = "insert into client_info set (
    id = '".$mysqli->real_escape_string('')."',
    first = '".$mysqli->real_escape_string($_POST['first'])."',
    last = '".$mysqli->real_escape_string($_POST['last'])."',
    phone = '".$mysqli->real_escape_string($_POST['phone'])."',
    mob = '".$mysqli->real_escape_string($_POST['mob'])."',

    ext_office = '".$mysqli->real_escape_string($_POST['ext_office'])."',
    srv = '".$mysqli->real_escape_string($_POST['srv'])."',
    stype = '".$mysqli->real_escape_string($_POST['stype'])."',
    voip = '".$mysqli->real_escape_string($_POST['voip'])."',

    agents = '".$mysqli->real_escape_string($_POST['agents'])."',
    password = '".$mysqli->real_escape_string($_POST['password'])."'
    )";

        //execute the query
        if( $mysqli->query($query) ) {
            //if saving success
            echo "User was created.";
        }else{
            //if unable to create new record
            echo "Database Error: Unable to create record.";
        }
        //close database connection
        $mysqli->close();

我得到的错误是脚本尝试将查询插入数据库

“数据库错误：无法创建记录。”

我试着看看我的表单上是否有任何输出，并且有，甚至试图只插入一个变量“first”仍然出错，不知道我在做错了什么

1 个答案:

答案 0 :(得分：3)

如果您在SET语句中使用INSERT语法，则不应在其周围使用括号。

-- One way to insert
INSERT INTO table SET col1 = 'val1', col2 = 'val2';

-- other way
INSERT INTO table(col1,col2) VALUES('val1','val2');

还可以使用原生errors provided by the driver查看您的查询有什么问题
