如何用php上传数据库和文件夹中的照片

How to upload photo in database and in folder with php

本文关键字：文件夹照片数据库何用 php 更新时间：2023-09-26

你好，我是这个论坛的新手，也是php的新手。我正在创建一个项目，我想将照片上传到数据库中，并将该照片存储在另一个文件夹中。我找到了一个教程，但它只针对他输入的用户名，而不是数据库中的用户名，例如下面显示的"member.php"。有人能帮我纠正我的PHP代码并让它为我的数据库工作吗？请有人帮我，我马上就需要。。。

在这种风格下，我的数据库被创建为

id |全名|用户名|密码|文件位置|

1|noname|malitet|3423@#4||

我想为数据库中存在的用户，例如，这个用户"malitet"已经登录，并且这个用户上传了头像。。。

这是我的php代码

文件名为upload.php

<?php
include ("connect.php");
$_SESSION['username']=malitet   ;
$username = $_SESSION['username'];

if (isset($_POST['submit']))
{
//get file attributes
$name = $_FILES['myfile']['name'];
$tmp_name = $_FILES['myfile']['tmp_name'];
if ($name)
{
//start upload process
$location = "avatars/$name";
move_uploaded_file($tmp_name,$location);
$query = mysql_query("UPDATE users1 SET imagelocation='$location' WHERE username='$username'");
die ("Your avatar has been uploaded!<a href='view.php'>Home</a>");

}
else
die ("Please select a file!");

}

echo "Welcome, ".$username."!<p>";
echo "Upload your image
<form action='upload.php' method='POST' enctype='multipart/form-data'>
File: <input type='file' name='myfile'><input type='submit' name='submit' value='Upload'>
</form>
";
?>

这是我的connect.php

<?php
$error = "Unable to connect";
$connect = mysql_connect("localhost","root","") or die($error);
mysql_select_db('phplogin') or die ($error);
?>

这是我的看法.php

<?php
include ("connect.php");
$username = $_SESSION['username'];
$query = mysql_query("SELECT * FROM users1 WHERE username='$username'");
if (mysql_num_rows('$query')==1)
die ("User not found!");
else
{
$row = mysql_fetch_assoc($query);
$location = $row['imagelocation'];
echo "<img src='$location' width='100' height='100'>";
}   
?>

这是我想上传文件的会员页面。。。或者，如果有其他方式，但我知道它很简单，如果有人能帮助我，请----member.php

<?php
session_start();
if (isset($_SESSION['username']))
echo "Welcome, ".$_SESSION['username']."!<br><a href='logout.php'>Log out</a><br><a href='changepassword.php'>Change password</a>";
else
die ("You must be logged in! <a href='index.php'>Click here</a> to return to login page");
?>

我希望你能帮助我…我在等待答案……：）：）：

hi有一些错误。总是在使用之前启动会话。好的使用此代码：

这是upload.php文件

<?php
session_start();
include ("connect.php");
$_SESSION['username'] = 'malitet';
$username = $_SESSION['username'];

if (isset($_POST['submit']))
{
//get file attributes
    $name = $_FILES['myfile']['name'];
    $tmp_name = $_FILES['myfile']['tmp_name'];
    if ($name)
    {
        //start upload process
        $location = "avatars/" . $name;
        move_uploaded_file($tmp_name, $location);
        $sql = "UPDATE users1 SET imagelocation='$location' WHERE username='$username'";
        $query = mysql_query($sql);
        echo "Your avatar has been uploaded!<a href='view.php'>Home</a>";
    }
    else die("Please select a file!");
}
echo "Welcome, " . $username . "!<p>";
echo "Upload your image
<form action='upload.php' method='POST' enctype='multipart/form-data'>
File: <input type='file' name='myfile'><input type='submit' name='submit' value='Upload'>
</form>
";
?>

========================================

这是view.php文件

<?php
include ("connect.php");
session_start();
$username = $_SESSION['username'];

$sql = "SELECT * FROM users1 WHERE username='$username'";
$query = mysql_query($sql);
if (mysql_num_rows($query) == 1)
{
    $row = mysql_fetch_assoc($query);
    $location = $row['imagelocation'];
    echo "<h1>Welcome</h1><br/>";
    echo "<img src='$location' width='100' height='100'>";
}
else
{
    echo "User Not found";
}
?>

==============================================

并且connect.php文件是可以的，所以您使用以前的

  <?php
  $images_arr = array();
            //This is the directory where images will be saved
        $target_dir = "uploads/";
        $target = $target_dir.$_FILES['photo']['name'];
            //$target = $target . basename( $_FILES['photo']['name']);
            //This gets all the other information from the form
        $name=$_POST['nameMember'];
        $bandMember=$_POST['bandMember'];
        $pic=($_FILES['photo']['name']);
        $about=$_POST['aboutMember'];
        $bands=$_POST['otherBands'];

            // Connects to your Database
        mysql_connect("Localhost", "remote", "remote123") or die(mysql_error()) ;
        mysql_select_db("test") or die(mysql_error()) ;
            //Writes the information to the database
        mysql_query("INSERT INTO dbProfiles (nameMember,bandMember,photo,aboutMember,otherBands)
        VALUES ('$name', '$bandMember', '$pic', '$about', '$bands')") ;
        //Writes the photo to the server
        if(move_uploaded_file($_FILES['photo']['tmp_name'], $target)){
                //Tells you if its all ok
            echo "The file ". $target_dir.$_FILES['photo']['name']. " has been uploaded, and your information has been added to the directory";
            $images_arr[] = $target;
        }
        else {
            //Gives and error if its not
            echo "Sorry, there was a problem uploading your file.";
        }
?>
