Question

在处理目录写入时，我似乎遇到了很多问题。如果有人可以请查看这个剧本，并告诉我它为什么不起作用，我会非常感激。

从表单上传文件后，我什么都没得到。它没有输出任何错误，它只是刷新。

谢谢，Lea

<?php include ('config.php');
 if( isset($_POST['submit']) ) {

$target = ''.$_SERVER['DOCUMENT_ROOT'].'/images/';
$target = $target . basename( $_FILES['photo']['name']) ;
$url = basename( $_FILES['photo']['name']) ;

if(move_uploaded_file($_FILES['photo']['tmp_name'], $target)) {
$moved =  "File has been moved to location $target";

$name = mysql_real_escape_string($_POST['photoname']);
mysql_query("INSERT INTO photos (photo_name, photo_image) VALUES ('$name',  '$url' )") or die(mysql_error());
$success = "Photo has been added!";

  } else {

$moved = "File has not been moved to $target";
$success = "Failed to upload:(";

  }

} ?>

Answer 1

不检查PHP代码是否有错误，首先要注意的是：

isset($_POST['submit'])

始终返回false。 input type =“submit”必须具有name属性“submit”才能发送：

<input type="submit" value="submit" name="submit" />

Answer 2

这是错误，在这样的提交按钮使用中：

<input type="submit" value="submit" name="submit" />

Answer 3

好的

<?php 
if( isset($_POST['submit']) ) {
 $target = 'images/';
 echo $target = $target . basename( $_FILES['photo']['name']) ;

 if(move_uploaded_file($_FILES['photo']['tmp_name'], $target)) {
  $moved =  "File has been moved to location $target"; 
  $success = "Photo has been added!";
 } 
 else { 
 $moved = "File has not been moved to $target";
 $success = "Failed to upload:(";
  }
} 
?>

简单的PHP上传表单不起作用
