[RESOLVED] Uploading zip files

[matman]

I found two articles in the search on this topic, but neither had a answer I could see.

I have a form I'm building. I upload a file. My form works on all files except a .zip file. I can upload imgages, text files, pdfs, ect, but it does not work with a zip.

I've reduced the code to bare minimums but still the same results. It won't work with a zip. In fact, I can't event get the code to recognize any $_REQUEST variables.

Any thoughts on how to resolve this.

My code:

<?php

test unziping a zip file.

if( $submit ){

pre_var_dump($_FILES);

if( $_FILES[$filename]['tmp_name'] ) {
	print "<p>I see the file</p>";
}else{
	print "<p>Could not see the files array</p>";
}

}else{
print "<p>I see nothing</p>";
}
?>
<form action="tw-zip-upload.html" method="post" enctype="multipart/form-data" />
<input type="hidden" name="max_file_size" value="300000" />
<input type="File" name="filename" size="40" />
Folder Name: <input type="text" name="foldername" size='20' /><br />
<p>
<input name="submit" type="Submit" value="Upload" />
</form>

In my code above, pre_var_dump() is a custom function in our shop for wrapping <pre> (pre) tags around a var_dump().

Why is your form action a .html page? Shouldn't it be a .php script that process the file upload?

Try this

<?php
# test unziping a zip file.
if( $_POST['submit'] ){
var_dump($_FILES);

if( $_FILES[$filename]['tmp_name'] ) {
print "<p>I see the file</p>";
}else{
print "<p>Could not see the files array</p>";
}
}else{
print "<p>I see nothing</p>";
}
?>
<form action="" method="post" enctype="multipart/form-data" />
<input type="hidden" name="max_file_size" value="300000" />
<input type="File" name="filename" size="40" />
Folder Name: <input type="text" name="foldername" size='20' /><br />
<p>
<input name="submit" type="Submit" value="Upload" />
</form>

Thanks for the tips, but nothing I've tried seems to work. This is a bit aggravating.

It seems that when I upload a .zip file, for some reason, the $POST and $FILES arrays are being blanked out or not set. The $_REQUEST array is now showing some wierd entries (see below).

If I upload an image, or text, or pdf, I can var_dump() all the arays all and they are filled as I would expect them to be, but a .zip is not.

I've done the following before any test on my submit button value:

<?php
var_dump($FILES);
var_dump($POST);
var_dump($_REQUEST);

test unziping a zip file.

if( $submit ){
print "<p>I see the file</p>";

}else{
print "<p>I see nothing</p>";
}
?>

Out put:

Files:
array(0) {
}

Post:
array(0) {
}

Request:
array(3) {
["shawtm"]=>
string(2) "11"
["utma"]=>
string(54) "23486248.1505127648.1193171054.1200412022.1202139289.3"
["utmz"]=>
string(96) "23486248.1202139289.3.3.utmccn=(referral)|utmcsr=launch.sha.cornell.edu|utmcct=/|utmcmd=referral"
}

I see nothing

Any thoughts? Back to Googling... 🙂

Thanks again. I appreciate the input.

I found that the file size of my zip seems to be the problem. It is 9.58 MB (10,055,680 bytes)

I tested with a smaller zip file 9,000 bytes and the form works. The $FILES, $REQUEST, and $_POST array all see the zip file. It is the 9.58 mb zip that cannot be seen.

php.ini:
; Maximum size of POST data that PHP will accept.
post_max_size = 32M
; Maximum allowed size for uploaded files.
upload_max_filesize = 32M

My file size is 9.58M

On my form:
<input type="hidden" name="MAX_FILE_SIZE" value="32000000" />

But still the zip file is not seen in any of the arrays mentioned.

Grrrr...

Okay, I found what appears to be my problem - or a co-worker found it.

I was using the same script (page) to upload the form and to process it. I added a second processing script to send the POST data to and everything works.

I still do not know why using the same page doesn't work, but I am now back to work.

Thanks to everyone for the help.
