PHP File Uploading - No File Uploaded Error
提问by acme
I've created an image uploading form , using twitter bootstrap and the jansy extention, using the next code section:
我创建了一个图像上传表单，使用 twitter bootstrap 和 jansy 扩展，使用下一个代码部分：
<form action="fileName.php" method="post" enctype="multipart/form-data">
<div class="fileupload fileupload-new" data-provides="fileupload">
<div class="fileupload-preview thumbnail" style="width: 200px; height: 150px;"></div>
<div>
<span class="btn btn-file"><span class="fileupload-new">Select image</span><span class="fileupload-exists">Change</span><input type="file" name="pic" id="pic"/></span>
<a href="#" class="btn fileupload-exists" data-dismiss="fileupload">Remove</a>
<button type="submit" class="btn">Upload</button>
</div>
</form>
on the fileName.php the following code is executed:
在 fileName.php 上执行以下代码：
print_r($_FILES);
if($_FILES["pic"]["error"] > 0){ /*image uploading has failed*/
echo "Error occured ".$_FILES["pic"]["error"];
}
else {
echo "image was uploaded successfully";
}
and returns the next message :
并返回下一条消息：
Array ( [pic] => Array ( [name] => [type] => [tmp_name] => [error] => 4 [size] => 0 ) ) Error occured 4
How come the file is not uploaded ? How could I solve this?
文件怎么没有上传？我怎么能解决这个问题？
Thanks.
谢谢。

Error 4 means UPLOAD_ERR_NO_FILE, so no file has been posted. I'd say the problem is somewhere in your javascript code or the components you used. Is any JavaScript error thrown?
错误 4 表示UPLOAD_ERR_NO_FILE，因此尚未发布任何文件。我会说问题出在您的 javascript 代码或您使用的组件中。是否抛出任何 JavaScript 错误？
Try a simple
尝试一个简单的
<form action="fileName.php" method="post" enctype="multipart/form-data">
<input type="file" name="pic">
</form>
to see if it works without any JavaScript plugins.
看看它是否在没有任何 JavaScript 插件的情况下工作。
