[Resolved] type of file

[mhalloran]

This isn't really a PHP question but It's part of a PHP script so here goes...

I have a script that uploads images and resizes them. I only want jpegs (no gifs) because I don't have 'gif create' in my GD library. Anyway, I have javascript alert when it's the wrong image type is selected and I have the PHP code check the type as well.

The thing I'd like to add is when the user hits the view button, the "type of file" is set to jpeg. I've seen programs do this but I don't know if it can be done through the browser. Anyone know?

What view button?
If you are asking: How does a PHP script set the content type, the answer is http://www.php.net/header

I'll try to explain better...

When you have the following tag..
<input type=file>
.. a browse button appears that prompts you to select a file from the local file system. The "type of file" field is set to "all files." I'm hoping that there is a way to set it to only show files with a certain extension. (eg .jpg, .jpeg)

NN2/3/4 and IE4/5 don't allow that currently.

The HTML 4 specs provide for an ACCEPT attribute to list the mime types
the server is going to process correctly and to allow the user
agent/browser to offer those mime types for selection
<INPUT TYPE="file"
ACCEPT="content-type-list"

thus
<INPUT TYPE="file"
ACCEPT="text/html, image/gif"

would specify html and gif files.
It seems however that current browsers don't support the ACCEPT
attribute.

Thanks for sharing your knowledge. I knew there had to be something like that.
