HOW TO MAKE A STATUS BAR

shams

Dear PHP Forum!
I want to make a Progress bar that shows me the Progress of Uploading File, as i have made an uploader that does not show the progress that how much file is uploaded.

If any body knows pls tell me

Short answer; You can't.

However, a thought struck my mind.

If you use a javascript popup window, launched onClick from the submit button,. Now this window should contain a meta refresh (every 5 seconds or so, depends).. And now, the tricky part;

You need to pass on the temporary file name where PHP writes the file (wich will, to say the least, be tricky.). And you need the complete file-size, wich will also be a bit tricky.

I don't think this one is solvable without alot of work, sorry. :/ Unless I'm not thinking clearly?

PHP alone will never do that. You'd have to be able to know the size of the file before it is completely uploaded, which is impossible because PHP is server-side and has absolutely no idea of what is going on on the cient's side.

To give you an idea, if you want to restrict uploads to certain types of files, your server has to accept whatever file is sent, check the file type and then, if it's not acceptable, discard it.

Maybe it's possible to check the size of the file using Javascript, but I have no idea if even Javascript can do that. And if it does, passing that information from the client to the server would be quite a remarkable stunt. I've been trying to pass on screen resolution to PHP through links in a long time, but still haven't found out how to do that because I don't know Javascript syntax to build the links.

Good luck, you're gonna need it.

This would be a usable technique to pass the width / height to test.php;

<?
print '<script language="JavaScript">';
print 'document.writeln(\'<a href="test.php?width=\' + screen.width + \'&height=\' + screen.height + \'">test</a>\');';
print '</script>';
?>
