<?php
echo $name= basename($_FILES['photoimg']['name']);
echo $size= basename($_FILES['photoimg']['size']);
?>
when I run the codes jquery display the following error: 当我运行代码jquery时,显示以下错误:
Uncaught TypeError: Illegal invocation
jQuery.extend.param.addjquery-1.7.1.js:7601
buildParamsjquery-1.7.1.js:7658
jQuery.extend.paramjquery-1.7.1.js:7621

jQuery.event.add.elemData.handle.eventHandlejquery-1.7.1.js:2875
It's hard to tell what the error message means exactly without seeing what comes back in your Ajax exchange. 在看不到Ajax交换返回的内容的情况下,很难说出错误消息的确切含义。 Your PHP code should not read 您的PHP代码不应该阅读
echo $var_name = ...
because that is an assignment. 因为那是一项任务。 Try the following... 尝试以下...
<?php
echo basename($_FILES['photoimg']['name']);
echo basename($_FILES['photoimg']['size']);
?>
Or just 要不就
print_r($_FILES);
