用php上传图片

我想用我的表单数据上传图片，但是出现错误。用php上传图片

在我的形式，该文件的线路有：

<li id="li_6" > 
    <label class="description" for="file">Filename:</label> 
    <div> 
     <input type="file" name="file" id="file"><br> 
    </div><p class="guidelines" id="guide_5"><small>Select the image to upload.</small></p> 
    </li>

这里是上传脚本：

if(isset($_POST['title'])) { 

      $allowedExts = array("gif", "jpeg", "jpg", "png"); 
      $temp = explode(".", $_FILES["file"]["name"]); 
      $extension = end($temp); 

      if ((($_FILES["file"]["type"] == "image/gif") 
      || ($_FILES["file"]["type"] == "image/jpeg") 
      || ($_FILES["file"]["type"] == "image/jpg") 
      || ($_FILES["file"]["type"] == "image/pjpeg") 
      || ($_FILES["file"]["type"] == "image/x-png") 
      || ($_FILES["file"]["type"] == "image/png")) 
      && ($_FILES["file"]["size"] < 60000) 
      && in_array($extension, $allowedExts)) { 
       if ($_FILES["file"]["error"] > 0) { 
       echo "Return Code: " . $_FILES["file"]["error"] . "<br>"; 
       } else { 
       echo "Upload: " . $_FILES["file"]["name"] . "<br>"; 
       echo "Type: " . $_FILES["file"]["type"] . "<br>"; 
       echo "Size: " . ($_FILES["file"]["size"]/1024) . " kB<br>"; 
       echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>"; 
       if (file_exists("upload/" . $_FILES["file"]["name"])) { 
        echo $_FILES["file"]["name"] . " already exists. "; 
       } else { 
        move_uploaded_file($_FILES["file"]["tmp_name"], 
        "media/uploads/" . $_FILES["file"]["name"]); 
        echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; 
       } 
       } 
      } else { 
       echo "Invalid file"; 
      } 
      $img_url = '/media/uploads/'.$_FILES["file"]["name"]; 
      $title = $_POST['title']; 
      $description = $_POST['description']; 
      $type = $_POST['description']; 
      $startPrice = $_POST['startPrice']; 
      $reservePrice = $_POST['reservePrice']; 
      $buyPrice = $_POST['buyPrice'];

也不太清楚怎么回事错了。我已经看过了。我的意思是代码直接来自手册..它应该工作！

不过，我得到这个错误：

> 
A PHP Error was encountered

哪条线是＃76？ – 2014-09-13 19:35:22

$ temp = explode（“。”，$ _FILES [“file”] [“name”]）; – user3175451 2014-09-13 19:36:50

您是否已将'enctype =“multipart/form-data”'添加到您的表单中？ – 2014-09-13 19:37:37

此错误最常见的原因是忘记设置enctype参数<form>的：

<form method="post" action="..." enctype="multipart/form-data">
