PHP文件上传不能在同一表单上发送POST数据

Answer 1

使用发布用户名和其他信息。

<form enctype="multipart/form-data" method="POST" action="uploader.php">
    <input type="hidden" name="uploader" value="avatar"/>
    <input type="hidden" name="username" value="<?php echo $_POST['username']; ?>" />
    ...
</form>

sample.php

<form enctype="multipart/form-data" method="POST" action="uploader.php">
  <br/>Username : <input type="text" name="username"/>
  <br/>Password : <input type="password" name="password"/>
    <input type="hidden" name="uploader" value="avatar"/>
   <br/>File : <input type="file" name="file"/>
   <br/><input type="submit"/>
</form>

uploader.php

<?php
  print_r($_POST)  // debug  $_POST
  print_r($_FILES) // file

  //OR
  echo $_POST["username"];
  $file=$_FILES["file"];
  print_r(file);
?>
