具有多个文件的Zend_File_Transfer不会同等上传 [英] Zend_File_Transfer w/multiple files does not upload equally
问题描述
< input name =image type =file/>
< input name =filetype =file/>
以下是处理上传的控制器中的代码块。其实还有一点，但是这是相关的一块：
$ $ p $ $ data $'image'] =（isset（$ _ FILES [image]）&& $ _FILES [image] [name]？$ _FILES [image] [name]：NULL）;
$ data ['file'] =（isset（$ _ FILES [file]）&& $ _FILES [file] [name]？$ _FILES [file] [ ] ： 空值）;
$ options = array（'ignoreNoFile'=> TRUE）;
$ upload = new Zend_File_Transfer（）;
$ upload-> setOptions（$ options）
- > addFilter（'Rename'，array（'target'=&> RESOURCES_IMG。$ data ['image']， （'overame'=> TRUE），'image'）
- > addFilter（'Rename'，array（'target'=> RESOURCES_FILES。$ data ['file']，'overwrite'=> TRUE ），'file'）
- > addValidator（'ImageSize'，false，array（'minwidth'=> 100，
'maxwidth'=> 100，
'minheight' ='100，
'maxheight'=> 100），'image'）
- > addValidator（'Extension'，false，'jpg'，'image'）;
if（！$ upload-> isValid（））
{
echo'< h1> Oops< / h1>< p>请更正以下错误： < hr />< / p>';
foreach（$ upload-> getMessages（）as $ key => $ val）
{
echo'< p>< strong>'。 $键。 '< / strong>< br />'。 $ val。 < / p为H.;
}
die;
}
else
{
$ upload-> receive（）;
} // if（！$ upload-> isValid（））
直截了当。 $数据的东西只是我抓住文件名，如果它存在或设置变量为NULL。我有我的addFilter（）和addValidator（）分割出来，只影响其相关的文件在这种情况下，图像或文件 - 表单字段的名称。
文件上传始终有效！然而，图像上传不是，更重要的是它将临时文件放到RESOURCES_FILES目录中，这根本没有任何意义。所以这个目录有PDF文件，除了像php8TJT13，phpXmOzQM等文件以外的任何其他文件。
我一直盯着这段代码，通过Stack Overflow搜索，出现，我找不到有这个问题的人。帮助！
好的，所以我做了更多的挖掘，结果可能是我的链接方式有问题 我使用 addFilter（）所以我决定向不同的方向移动，试图隔离每个文件并单独处理它。到目前为止，它似乎工作。这里是修改的代码：
$ p $ $ data ['image'] =（isset（$ _ FILES [image]）& ;& $ _FILES [image] [name]？$ _FILES [image] [name]：NULL）; 所以我告诉循环跳过那个和
$ data ['file'] =（isset（$ _ FILES [file]）&& $ _FILES [file] [name]？$ _FILES [file] [ ] ： 空值）;
$ upload = new Zend_File_Transfer（）;
$ files = $ upload-> getFileInfo（）;
$ options = array（'ignoreNoFile'=> TRUE）;
$ upload-> setOptions（$ options）;
$ b foreach（$ files as $ field => $ contents）
{
if（！strlen（$ contents [name]））
{
继续;
$
$ b $ //上传图片的指令
if（$ field =='image'）
{
$ upload-> addFilter（'重命名'，array（'target'=> RESOURCES_IMG。$ data ['image']，'overwrite'=> TRUE），'image'）
- > addValidator（'ImageSize'，false，array （'minwidth'=> 100，
'maxwidth'=> 100，
'minheight'=> 100，
'maxheight'=> 100），'image'）
- > addValidator（'Extension'，false，'jpg'，'image'）;
上传文件
if（$ field =='file'）
{
$ upload-> addFilter（'重命名'，数组（'target'=> RESOURCES_FILES。$ data ['file']，'overwrite'=> TRUE），'file'）;
$ b $ if（！$ upload-> receive（$ field））{
echo'< h1> Oops< / h1>< p>请更正以下错误：< hr />< / p>';
foreach（$ upload-> getMessages（）as $ key => $ val）
{
echo'< p>< strong>'。 $键。 '< / strong>< br />'。 $ val。 < / p为H.;
}
die;
// return;
$ foreach
code $
$ h $伪$解释
getFileInfo（）获取可用的文件数组，然后循环遍历每个文件。在我的第一个 for 循环的开头，我检查这个文件是否有名字，如果没有名字，我假设这个字段是空的， code> NULL 继续。
一旦我在循环中，我只是使用一个简单的条件匹配我的上传指令与适当的表单字段。其余的应该是相当自明的，如果你是Zend的东西。
希望这有助于其他人在我的困境。如果你是一个Zend大师，也许你可以评论我的解决方案或修复造成这个问题的错误。可能会有更多的Zend的方法，但它现在正在工作，这感觉很好。

为什么我认为这是 addFilter（）方法的链接，请参阅示例＃3（下面）中的注释：
注意：即使允许多次设置相同的过滤器，在同一个过滤器中使用不同的选项时，这样做也会导致问题。

随机的博客文章激励我尝试隔离每一个，我打电话给它，上传指令，虽然我不知道这是所谓的：
$ b
Weird title, yes, but the problem is simple; simply aggrevating. I have a form, that I built without using Zend_Form, and it has two file uploads:
<input name="image" type="file" />
<input name="file" type="file" />
Here is the chunk of code from my controller that is handling the upload. There's actually a little more, but this is the relevant piece:
$data['image'] = (isset($_FILES["image"]) && $_FILES["image"]["name"] ? $_FILES["image"]["name"] : NULL);
$data['file'] = (isset($_FILES["file"]) && $_FILES["file"]["name"] ? $_FILES["file"]["name"] : NULL);
$options = array('ignoreNoFile' => TRUE);
$upload = new Zend_File_Transfer();
$upload->setOptions($options)
->addFilter('Rename', array('target' => RESOURCES_IMG . $data['image'], 'overwrite' => TRUE), 'image')
->addFilter('Rename', array('target' => RESOURCES_FILES . $data['file'], 'overwrite' => TRUE), 'file')
->addValidator('ImageSize', false, array('minwidth' => 100,
'maxwidth' => 100,
'minheight' => 100,
'maxheight' => 100), 'image')
->addValidator('Extension', false, 'jpg', 'image');
if (!$upload->isValid())
{
echo '<h1>Oops</h1><p>Please correct the following errors: <hr /></p>';
foreach ($upload->getMessages() as $key => $val)
{
echo '<p><strong>' . $key . '</strong><br />' . $val . '</p>';
}
die;
}
else
{
$upload->receive();
} // if (!$upload->isValid())
It's pretty straight forward. The $data stuff is just me grabbing the filename if it's there or setting the variable to NULL. I have my addFilter() and addValidator() segmented out to only affect their relevant files in this case "image" or "file" - the names of the form fields.
The "file" upload always works! However, the "image" upload doesn't and what's more it puts the temporary file into the RESOURCES_FILES directory which makes no sense at all. So that directory has PDFs and whatever else in addition to files like php8TJT13, phpXmOzQM, etc.
I have been staring at this code and searching through Stack Overflow and whatever Google will turn up and I can't find anyone having this problem. Help!
Alright, so I did more digging and it turns out there may be an issue with the way I was chaining addFilter() so I decided to move in a different direction, trying to isolate each file and handle it's upload individually. So far it appears to be working. Here is the revised code:
$data['image'] = (isset($_FILES["image"]) && $_FILES["image"]["name"] ? $_FILES["image"]["name"] : NULL);
$data['file'] = (isset($_FILES["file"]) && $_FILES["file"]["name"] ? $_FILES["file"]["name"] : NULL);
$upload = new Zend_File_Transfer();
$files = $upload->getFileInfo();
$options = array('ignoreNoFile' => TRUE);
$upload->setOptions($options);
foreach ($files as $field => $contents)
{
if(!strlen($contents["name"]))
{
continue;
}
// upload instructions for image
if ($field == 'image')
{
$upload->addFilter('Rename', array('target' => RESOURCES_IMG . $data['image'], 'overwrite' => TRUE), 'image')
->addValidator('ImageSize', false, array('minwidth' => 100,
'maxwidth' => 100,
'minheight' => 100,
'maxheight' => 100), 'image')
->addValidator('Extension', false, 'jpg', 'image');
}
// upload instructions for file
if ($field == 'file')
{
$upload->addFilter('Rename', array('target' => RESOURCES_FILES . $data['file'], 'overwrite' => TRUE), 'file');
}
if(!$upload->receive($field)) {
echo '<h1>Oops</h1><p>Please correct the following errors: <hr /></p>';
foreach ($upload->getMessages() as $key => $val)
{
echo '<p><strong>' . $key . '</strong><br />' . $val . '</p>';
}
die;
//return;
}
} // foreach
Pseudo Explanation
I use the getFileInfo() to grab an array of the files available to me then I loop over each. At the beginning of my first for loop I check to see if this file has a name, if it doesn't have a name I assume that field was left blank and is NULL so I tell the loop to skip over that and continue.
Once I'm in the loop I'm just matching my upload directives with the appropriate form field using a simple conditional. The rest should be fairly self-explanatory if you're into Zend stuff.
Hopefully this helps someone else that was in my predicament. If you are a Zend guru maybe you can comment on my solution or fix the bug that's causing the issue. There may be a more "Zend" way of doing it, but it's working now and that feels damn good.

Why I thought it was the chaining of the addFilter() method, see the note under Example #3 (below):
Note: Note that even though setting the same filter multiple times is allowed, doing so can lead to issues when using different options for the same filter.

A random blog article that inspired me to try isolating each, I'm calling it, "upload directive" although I'm not sure if that's what it's called:
