Image Uploads/Display (Read 3018 times)

	Hi, I'm writing a program which includes a guestbook for which I would like to make it possible for posters to upolad an image. The problem: I need a snippet, subroutine or whatever for this as I have never worked with file uploading. The things I need control of are---file size limits, file types allowed, and file renaming using the same file extension. If it makes any difference I'm using the cgi-lib.pl. The reason for file renaming: each poster will have a unique code to be associated with ther name and email address so that a person can upload a pic at a later date or change their pic--the unique file name could simply be overwritten in the case of a new pic plus it would eliminate any chance of two images having the same name ALSO--I'm looking for something so that when the pics are displayed a control to limit the display sizes such as maximum width, height so as not to cause the images to appear out of proportion. Thanx much for any help possible.

Look into the Profile.pl and/or Post.pl there the avatar and attachments upload, size limit and renaming is done well.

For the display sizing use our resize_images JavaScript function in YaBB.js.

	Oh my, where do I start?? I looked through those files and got lost quick. At this point I only have the name for the file upload on the form and the name the file will be changed to. In profile.pl around line 630 I see where they begin talking about the images(couldn't find in post.pl). Can't find however, file types allowed or the errors for wrong types or about renaming them. Basically I only have the <input type="file"> so far. Also, I looked at the YaBB.js file under the image resizing and in that one possibly the variables for the sizing(but not positive on that one) I realize I'm asking alot here and apologize for that but uploads and image sizing are all new to me.

To begin you must use other <form tag:

Find in Post.pl

Code

		if (&AccessCheck($currentboard, 4) eq "granted" && $allowattach && ${$uid.$currentboard}{'attperms'} == 1) {
			$yymain .= qq~<form action="$scripturl?$thecurboard" method="post" name="postmodify" enctype="multipart/form-data" onsubmit="if(!checkForm(this)) {return false} else {return submitproc()}">~;
		} else {

the input tag must look like this:

Code

<input type="file" name="fileX" />

Then give a look into this loop in Post.pl
I assume you want to use this within YaBB because otherwise you must know more about CGI.pm

Code

		if ($numcount < 2) { &Preview("$post_polltxt{'38'}"); }
	}

	my ($file,$fixfile,@filelist,%filesizekb);
	for (my $y = 1; $y <= $allowattach; ++$y) {
		$file = $CGI_query->upload("file$y") if $CGI_query;
		if ($file) {
			$fixfile = $file;
			$fixfile =~ s/.+\\([^\\]+)$|.+\/([^\/]+)$/$1/;

................

	}
	#Create the list of files
	$fixfile = join(",", @filelist);

Now everything should be fine. You can store the name of the files in $fixfile and call them on your browser. Wink

Good luck!

	No, this isn't to be used in YaBB. Actually its part of a script for a Christian website. Anyway, I tried it to no avail. What a time to not know anything about CGI.PM. I really appreciate your time spent however--God Bless
