Question

我有一个PHP代码，我想将表单数据保存到datatase中。我测试，我可以写＆＃34;插入表值（）＆＃34;直接在数据库中，它可以插入到数据库中。

但是在我的界面中，当我点击提交按钮时，我无法保存到db？

<?php
    include('connectWorkbench.php');
    $sql=mysql_query("SELECT * FROM Properties");
    $epr = '';
    $msg = '';
    if(isset($_GET['epr']))
        $epr=$_GET['epr'];
    //++++++++++++++++++++++++++++++save record++++++++++++++++++
    if($epr=='save')
    {
        $pid=$_POST['pid'];
        $aid=$_POST['aid'];
        $uid=$_POST['uid'];
        $code=$_POST['code'];
        $name=$_POST['name'];
        $description=$_POST['description'];
        $parking=$_POST['parking'];
        $sfeet=$_POST['sfeet'];
        $price=$_POST['price'];
        $distance=$_POST['distance'];
        $owner=$_POST['owner'];

        $a_sql=mysql_query("INSERT INTO Properties VALUES($pid,$aid,$uid,$code,'$name','$description','$parking',$sfeet,'$price','$distance','$owner')");
        if($a_sql)
            header("location:index.php");
        else
        {
            $msg='Error:'.mysql_error();
            echo '$msg';
        }


    }

?>
<!--$query = mysql_query("SELECT * FROM Contact");
    while($row = mysql_fetch_array($query))
    {
        $id = $row['contact_ID'];
        $fname = $row['first_name'];
        $midname = $row['middle_name'];
        $lname = $row['last_name'];
        echo '<br />' .$id. ':' . $fname . '<br />';
    }
$query2 = mysql_query("SELECT * FROM Properties");
    while($row = mysql_fetch_array($query2))
    {
        $id = $row['property_ID'];
        $addressID = $row['property_address_ID'];
        $ownerID = $row['owner_user_ID'];
        $propertyCode = $row['property_type_code'];
        echo '<br />' .$id. ':' . $addressID . ':' . $ownerID .':'. $propertyCode .'<br />';
    }

Answer 1

看起来你的SQL查询可能是错误的。您需要包括每个项目的提交位置：

您的代码：

INSERT INTO Properties VALUES（$ pid，$ aid，$ uid）

您需要将其更改为：

INSERT INTO属性（pidrow，aidrow，uidrow）VALUES（$ pid，$ aid，$ uid）

这会使$ pid输入到pidrow，$ aid输入到aidrow等等。

Answer 2

Ya，您还需要在查询中将列名称指定为：

INSERT INTO Properties(col1, col2, col3) 
VALUES(val1, val2, val3)

您还必须连接到数据库

使用：

mysqli($con, "query");

单击“提交”按钮时无法将表单数据保存到数据库中
