如何使用php上傳數據庫和文件夾中的照片

Question

---

你好，我是新的在這個論壇ande我是新的php。我正在創建一個項目，並且我想要將照片上傳到數據庫中，並將該照片存儲在另一個文件夾中。我找到了一個教程，但它只是爲了他輸入的用戶名，而不是在數據庫中的用戶名，例如在下面顯示的「member.php」中。有人可以通過更正我的PHP代碼並使其適用於我的數據庫來幫助我嗎？請讓別人幫我，我需要它immidiately ...

在這種風格我的數據庫中創建

---

ID |全名|用戶名|密碼| filelocation |

---

1 | noname | malitet | 3423 @！＃4 | |

---

我想在數據庫上存在的用戶，例如該用戶「malitet」被記錄在這個用戶上傳頭像...

這裏是我的PHP代碼

的文件名爲upload.php的

<?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> 

"; 

?> 

這裏是我的connect.php

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

這裏是我的view.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'>"; 

} 

?> 

這是到了我要上傳的文件會員頁面...或者，如果存在任何其他的方式，但我知道它很簡單，如果有人能幫助我請---- 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"); 

?> 

我希望你能幫助我......我在等待答案... :) :) :)

Answer 1

喜有一些錯誤。 總是使用前啓動會話它.Ok 使用此代碼：

這是upload.php的文件

<?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> 

"; 
?> 

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

這是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"; 
} 
?> 

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

所以你用

和connect.php文件是確定你的前一個

<?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.";
