PHP文件上传脚本未上传

Question

一页上有一个小表格，其中包含以下代码，

<div class="postcomment">
<form id="comments" action="insertcomment.php" method="POST" enctype="multipart/form-data">
Comment: <input type="text" name="comment" id="commentfield">
<input type="submit" name="submit" value="Post comment" class="button">
<br>
<input type="hidden" name="MAX_FILE_SIZE" value="1048576" />
Image: <input type="file" name="image" />
<br>
</div>

一旦用户通过浏览添加图片，表单便转到下面的insertcomment.php代码

$target_path = "images/";

$file_path = $target_path . basename( $_FILES['uploadedfile']['name']); 

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $file_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}

并且由于某种原因它显示了错误并且没有显示在图像目录中，该错误是：分析错误：语法错误，/homepages/21/d417005970/htdocs/rk8479/htdocs/insertcomment.php中第18行的意外T_IF

试试这个HTML

<div class="postcomment">
<form id="comments" action="insertcomment.php" method="POST" enctype="multipart/form-data">
Comment: <input type="text" name="comment" id="commentfield">
<br>
Image: <input type="file" name="image" />
<br>
<input type="submit" name="submit" value="Post comment" class="button">
</form>
</div>

PHP代码（您正在尝试在同一页上使用它，您可以检查if（isset（$ _ POST ['submit']））

if($_FILES['image']['size'] > 0){
        $allowedExts = array("jpg", "jpeg", "gif", "png");
        $extension = end(explode(".", $_FILES["image"]["name"]));
        if ((($_FILES["image"]["type"] == "image/gif")
        || ($_FILES["image"]["type"] == "image/jpeg")
        || ($_FILES["new_image"]["type"] == "image/png")
        || ($_FILES["image"]["type"] == "image/pjpeg"))
        && ($_FILES["image"]["size"] < 1048576)
        && in_array($extension, $allowedExts))
          {
          if ($_FILES["image"]["error"] > 0)
            {
            $error_message = $_FILES["image"]["error"];
            }
          else
            {

            if (file_exists("images/" . $_FILES["image"]["name"]))
              {
              $error_message = $_FILES["image"]["name"] . " " . $LANG['image_exist'];
              }
            else
              {
              if(move_uploaded_file($_FILES["image"]["tmp_name"],
              "images/" . $_FILES["image"]["name"])) {  
              // success
              $image_name = $_FILES["image"]["name"];
              } else {
              $error_message = "Upload Failed!";
              }
              }
            }
          }
        else
          {
          $error_message = "Error: May be different ext or size";
          }
    }
