Hi,
I would like to implement some simple file upload / download
functionality.
I tried the following approach:
When uploading a file via the <input type="file" ...> tag the value
of $_FILES['file']['type'] is retrieved (application/octet-stream in
the case of a simple text file), stored in the database and later
reused when somebody tries to download the file to set the
'content-type' header :
$request = $this->getRequest();
$response = $this->getResponse();
[...]
$this->_helper->viewRenderer->setNoRender();
[...]
>>> $response->setHeader('content-type', $contentType);
$response->setHeader('content-length', $contentLength);
echo file_get_contents($filepath);
This seems to be the wrong approach: when trying to download the file
only an empty page is shown.
When uncommenting the line "$response->setHeader('content-type',
$mimetype);" and downloading a text file the content is shown
correctly.
The up/download of binary files on the other side (for example a
simple hello-world program) doesn't work.
Here my question:
- should I use
$response->setHeader('content-type', $type);
$response->setHeader('content-length', $size);
echo file_get_contents($filepath);
at all?
Or should I simply skip the first two lines and just use
echo file_get_contents($filepath);
?
- If the header has to be used, how can I determine the correct
'content-type' to use for some uploaded file?
Any kind of file - Images, binary files, text files etc. -
might be up- and downloaded by the user.
Thanks for your help, Dietrich
