上传图片.php

  define ('MAX_FILE_SIZE', 1024 * 50); 

  if ((isset($_POST['MM_insert'])) && ($_POST['MM_insert'] =="uploadImg")) {

    // make sure it's a genuine file upload  
    if (is_uploaded_file($_FILES['image']['tmp_name'])) {
      // replace any spaces in original filename with underscores
      $filename = str_replace(' ', '_', $_FILES['image']['name']);
      // ...
    }
  }

HTML 模板:

<form action="UploadImage.php" method="post" 
      enctype="multipart/form-data"  name="uploadImg" id="uploadImg">
  <p>
    <input type="hidden" name="MAX_FILE_SIZE" value="MAX_FILE_SIZE" />
    <label for="image">Upload image:</label>
    <input type="file" name="image" id="image" /> 
  </p>

  <p>
    <input type="submit" name="upload" id="upload" value="Upload" />
  </p>

  <input type="hidden" name="MM_insert" value="uploadImg" />
</form>  

这给出了一个错误;undefined index: image in ....... UploadImage.php 我也给出了 enctype 表单属性...bt 它给出了一个未定义的索引错误:(

你能发布整个php吗?您的 php 代码中没有 session_start() 。

编辑:

define ('MAX_FILE_SIZE', 1024 * 50); 必须以 KB 为单位,而不是 MB...

尝试

define ('MAX_FILE_SIZE', 1024000 * 50);
