如何将上传图片的位置路径插入数据库中用户的pic_location？

所以我设法通过php上传图片到一个文件夹但是我的问题现在就是那个，如果我想实现那个，我不知道查询会是什么样的......

会员在上传图片时登录，以便SESSION正在运行。

我会给你我的代码看看，如果你能发现该怎么做......

由于

我的picUpload.php （我在哪里上传图片以及我想将位置路径插入到用户的pic_loaction列中的用户）

    <?php
         include 'connect.php';
         include 'header.php';

         if(isset($_SESSION['signed_in']) && $_SESSION['signed_in'] == true)
        {
             //This is the directory where images will be saved 
             $target=$_SERVER['DOCUMENT_ROOT'] . "/avatars/" . basename( $_FILES['file']['name']); 

             //This gets all the other information from the form 
             $pic_location=($_FILES['file']['name']); 

             //Writes the information to the database
             $sql = "UPDATE users SET pic_location='$target' WHERE user_id=" . $_SESSION['user_id'];

             //Writes the photo to the server 
             if(move_uploaded_file($_FILES['file']['tmp_name'], $target)) 
             { 

             //Tells you if its all ok 
             echo "The file ". basename( $_FILES['file']['name']). " has been uploaded, and your information has been added to the directory"; 
             } 
             else { 

             //Gives and error if its not 
             echo "Sorry, there was a problem uploading your file."; 
             }

        }
        else
        {
            //nothing
        }
?>

我的connect.php

<?php 
    session_start();
    //connect.php

    $server = 'localhost';
    $username = 'root';
    $password = '';
    $database = 'mydatabase';

    if(!mysql_connect('localhost', 'root', ''))
    {
        exit('Error: could not establish database connection');
    }
    if(!mysql_select_db($database))
    {
        exit('Error: could not select the database');
    }
?>

，这是我的database.sql文件中的用户表

CREATE TABLE users (  
user_id     INT(8) NOT NULL AUTO_INCREMENT,  
user_name   VARCHAR(30) NOT NULL,  
user_pass   VARCHAR(255) NOT NULL,

user_level  INT(8) NOT NULL,  
pic_location  VARCHAR(255) NOT NULL,  
UNIQUE INDEX user_name_unique (user_name),  
PRIMARY KEY (user_id)  
);

Answer 1

将变量$target存储为pic_location，查询不插入，应该是更新查询。

Answer 2

正如punit所写，使用变量$ target来更新用户的记录。在查询中，使用UPDATE而不是INSERT，确保定义用户的ID（您现在拥有的INSERT只是添加一个新行，但是您想要修改现有行，因此您需要一个WHERE子句并且你应该在查询中使用它之前清理$ target，否则你会盲目地注入SQL。
