用php和SQL上傳圖片

Question

我想讓用戶上傳個人資料圖片！

我想上傳文件（圖片），將字符串/路徑和文件名存儲在我的數據庫中，並將文件移動到我的圖像文件夾！但我沒有分類如何做到這一點！

我有幾個文件，你可以看看，看看有什麼我試圖做...

picUpload.php（代碼上傳圖片）

<?php 
    if(($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg") && ($_FILES["file"]["size"] < 50000)) 
    { 
     if ($_FILES["file"]["error"] > 0) 
     { 
      echo "Return code: " . $_FILES["file"]["error"] . "<br/>"; 
     } 
     else 
     { 
      echo "Upload: " . $_FILES["file"]["name"] . "<br/>"; 
      echo "Size: " . $_FILES["file"]["size"]/1024 . " Kb<br/>"; 

      if(file_exists("upload/" . $_FILES["file"]["name"])) 
      { 
       echo $_FILES["file"]["name"] . " already exists!"; 
      } 
      else 
      { 
       move_uploaded_file($_FILES["file"]["tmp_name"], 
       "upload/" . $_FILES["file"]["name"]); 
       echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; 
      } 
     } 
    } 
    else 
    { 
     echo "Invalid file!"; 
    } 
?> 

然後profile.php（其中用戶上載的知情同意並存儲在DB ???）

<?php 

     //create_cat.php 
     include 'connect.php'; 
     include 'header.php'; 

     if(isset($_SESSION['signed_in']) == false || isset($_SESSION['user_level']) != 1) 
      { 
       //the user is not an admin 
       echo '<br/>'; 
       echo 'Sorry! You have to be <a href="/signin.php"><b>logged in</b></a> to view your profile.'; 
       echo '<br/><br/>'; 
      } 
      else 
      { 
       $sql = mysql_query("SELECT * FROM users"); 

       if ($users = mysql_fetch_array($sql)){ 
        echo 'Profile of '.$_SESSION['user_name']; 
        echo '<br/><br/>'; 
        echo '<h2>Info about you:</h2>'; 
        echo '<br/>'; 
        echo 'Logged in as '.$_SESSION['user_name']; 
        echo '<br/><br/>'; 
        echo 'Your email address: '.$_SESSION['user_email'].' (1 = admin || 0 = user)'; 
        echo '<br/><br/>'; 
        echo 'Your user level: '.$_SESSION['user_level'].' (1 = admin || 0 = user)'; 
        echo '<br/><br/>'; 
        echo 'Your friends: //friends come here'; 
        echo '<br/><br/>'; 
       } 

       ////////////////////////////////////////////////////////////////////////////// 
       ////////////////////  STORE STRING IN DATABASE?????  ////////////////// 
       ////////////////////////////////////////////////////////////////////////////// 

       echo 'Do you want a profile picture? Uplaod image!'; 
       echo '<form action="picUpload.php" method="post" enctype="multipart/form-data"> 
         <label for="file">Filename: </label> 
         <input type="file" name="file" id="file"/> 
         <br /> 
         <input type="submit" name="submit" value="Submit" /> 
        </form>'; 

       /////////////////////////////////////////////////////////////      
       //HOW DO I INSERT/store the string/path in my database now???    
       ///////////////////////////////////////////////////////////// 

       $sql = "INSERT INTO users('pic_location') 
         VALUES('" . mysql_real_escape_string($_POST['pic_location']) . "',NOW(),0)"; 

      /*$result = mysql_query($sql); 
      if(!$result) 
      { 
       //something went wrong, display the error 
       echo 'Something went wrong while registering. Please try again later.'; 
       //echo mysql_error(); //debugging purposes, uncomment when needed 
      } 
      else 
      { 
       echo 'Succesfully registered. You can now <a href="signin.php">sign in</a> and start sharing links.'; 
      }*/ 

       //echo 'Welcome, ' . $_SESSION['user_name'] . '! <br /><br/><br/><a href="index.php"><b>Proceed to the link sharing</b></a>.'; 
       /////////////////////////////// 
       /// adding users as friends /// 
       /////////////////////////////// 

       //while($user = mysql_fetch_array($result)) 
       //echo $user['user_name'].' 
        //<a href="addfriend.php?user='.$user['id'].'">ADD TO FRIENDS</a><br/>'; 


       //NOW I WANT TO MAKE A SPECIFIC "ADD AS FRIEND" LINK NEXT TO EACH USER 


      } 
      include 'footer.php'; 
?> 

AN D如何將文件移動到我的圖像文件夾？ 請幫助我這個！

謝謝！

如果你有這種錯誤，它可能是文件權限問題或文件夾「upload /」不存在。檢查路徑。
