[RESOLVED] File upload help (max file size)

turtleton09

Hope someone can help with this. Have a file upload script that all seemed to be working fine, using the PHP component that resizes images (forget it's name).

So it checks the file name is unique, checks it's a jpg, gif, bmp or photoshop file as requires, and has a max file size line to limit it's size.

However, it seems that with any file over around 2MB, it's not uploading, and we're getting the error about it not being a jpg or gif.

The line in the upload page is :

<input name="uploadFile" type="file" size="55">
<input type="hidden" name="MAX_FILE_SIZE" value="80000" />

It did have a default value of 25000 but I changed it to 80000, but still the same problem.

Some code from the validation page :

$ValidationFailed = false;

if (($_FILES["uploadFile"]["type"] == "image/gif") 
|| ($_FILES["uploadFile"]["type"] == "image/pjpeg")
|| ($_FILES["uploadFile"]["type"] == "image/tif")
|| ($_FILES["uploadFile"]["type"] == "image/png")
|| ($_FILES["uploadFile"]["type"] == "image/photoshop")
|| ($_FILES["uploadFile"]["type"] == "image/bmp")) 
  { 
  if ($_FILES["uploadFile"]["error"] > 0) 
    { 
     $ValidationFailed = true; 
     $FTGvalid_file_errmsg = "Error: " . $_FILES["file"]["error"]; 
     $ErrorList .= $FTGvalid_file_errmsg . '<br/>'; 
    } 
  } 
else 
  { 
  $ValidationFailed = true; 
  $FTGvalid_file_errmsg = "Please select a valid image file type. The library supports .jpg, .gif, and .png files."; 
  $ErrorList .= $FTGvalid_file_errmsg . '<br/>'; 
  }

if (!empty($_FILES['uploadFile']['name']) && file_exists("Photos/" . $_FILES["uploadFile"]["name"]) && is_file('Photos/' . $_FILES['uploadFile']['name'])) 
{ 
  $ValidationFailed = true; 
  $FTGvalid_file_errmsg = "This file has already been uploaded. If you are sure it's a new photo please rename it before uploading to the library."; 
  $ErrorList .= $FTGvalid_file_errmsg . '<br/>'; 
    }

Any ideas?

As you'll see on the manual page [man]features.file-upload[/man], the "MAX_FILE_SIZE" element must precede the file input field.

Also, this hidden element isn't what PHP actually limits the upload to; if you'll look in your php.ini file, you'll see a directive called "upload_max_filesize. Bump this value up from what is probably "2M" to whatever you wish the new max size to be. You should also increase the "post_max_size" directive to a value slightly over the upload_max_filesize (as this also accounts for all other data in the form).

No joy, I'm afraid - sussed out to change the max file upload size in the php.ini file, but didn't work, and have been trying

ini_set('upload_max_filesize', '8M');

in the file with the upload script, but that's not working either.

Added in :

print_r($_FILES["uploadFile"]["type"]);

to have a look, and it's drawing a blank with files > 2MB still, and correctly displaying image/pjpeg for images < 2MB.

If you'll look in the manual's description for the upload_max_filesize directive, you'll see that you can only change this setting in the php.ini file OR in a .htaccess file using the 'php_value' directive (assuming you're running Apache and PHP is loaded as a module, not a CGI binary).

If you get rid of the ini_set() command, and just do a phpinfo(), does the table reflect the change you've made in your .ini file (does it show the new value of 8M)?

Also, out of curiosity, have you tried files that are a bit under 8M (since your post_max_size is probably 8M as well)?

turtleton09

Cheers - I found it in the php.ini file and bumped it up there, but didn't work.

After another rummage, people had suggested adding in

ini_set('upload_max_filesize', '8M');

to the file with the upload script, which I presumed was a way of forcing the value directly.

I added in

print_r($_FILES["uploadFile"]["type"]);

And it's not displaying anything for the file type with images >2MB, but is correctly displaying

image/pjpeg

for images <2MB

So it's all the more confusing, as it's as tho' for some reason files over 2MB are the script isn't recognising the file type.

The test file I've been using is around 3.5MB, so figured 8 was OK as an upper limit.

I'm home now, so won't be able to have a play around until Tuesday, but php info() is a good shout as the next thing to check.

bradgrafelman

Though the default post_max_size is 8M, you might want to check that value in phpinfo() as well.

Also... have you tried looking in $_FILES['uploadFile']['error'] to see if PHP is generating any kind of error message?

turtleton09

Nope - I'll try these out next week to see what they throw up, and post back the results then.

Cheers for the replies and have a good Easter.

Just looking at this again this morning - phpinfo() is showing 8M as it should.

How do I look in $_FILES['uploadFile']['error']?

I've found a file : php_error.log, if that's it?

The same way you would any other variable.

There's a section in the File Uploads chapter of the manual that will explain what (if anything) you'll find in it.

turtleton09

D'oh - print_r?

Any road up, just spotted that the upload_max_filesize is still showing as 2M in phpinfo(), even tho' I've changed it to 8M in the php.ini file, and added

<?php
ini_set('upload_max_filesize', '8M'); 
?>

to the top of the page with the upload script.

I changed the post_max_size to 9M in the php.ini, but it's still showing as 8M in the phpinfo() too.

What could be stopping this from taking effect, if it's changed in the php.ini file, and forced using ini_set?

turtleton09

OK - stop the clock.

Stopping and restarting the Apache server did the trick.
