resizing/uploading doesnt work with large-dimensioned images

First of wanted to say that you have created a great  product.

I am having some problems with the image resizing feature (foto_upload.php). Evevry time i upload a file it says that uploaded and processed. But i dont see the file(s) in my directory. Interesting thing is when i upload really small images like 150x100 it uploads. But as soon as i use bigger images nothing happens. Can you please help me?

Thanks!!

I am not familliar with Olaf's classes, but this could be a problem of your php.ini (max_post_size)

Nikolas,

The max size in my php.ini is upto 4MB. And in any case, it should still throw me an error of "The uploaded file exceeds the max. upload filesize directive in the server configuration."

My files ar all around 1MB.

hello,

do you have a link to the upload form you're using? and place a phpinfo file on the host where the upload doesn't work.

Hi Olaf,

I am not entirely sure what you mean but I am just using this to repost to the same page.

<form enctype="multipart/form-data" method="post" action='.$_SERVER["PHP_SELF"];echo '?id='.$id; ...................

Let me know if you wanted to know something else.

I need to see the whole form and your php cofiguration...

Ok..heres the code...the top portion is all your code...except where i change the file paths. let me know if any Q's:


<?php //require_once ('../includes/config.inc') ?>
<?php require_once ("../../mysql_connect.php") ?>
<?php include ("../includes/customer_header.html") ?>
<?php include ("../includes/upload_class.php") ?>

<?php if(isset($_SESSION["username"]))
{
// Check for a valid user ID, through GET or POST.
if ( (isset($_GET['id'])) && (is_numeric($_GET['id'])) ) { // Accessed through view_users.php
     $id = $_GET['id'];
} elseif ( (isset($_POST['id'])) && (is_numeric($_POST['id'])) ) { // Form has been submitted.
     $id = $_POST['id'];
} else { // No valid ID, kill the script.
     echo '<h1 id="mainhead">Page Error</h1>

that was too much...

The max filesize value in your form is 1MB (1024*1024)

I am actually having the same problem.  This script will only upload an image if it is within the specified file dimensions.  For example, I set my max to:
   var $x_max_size = 600;
   var $y_max_size = 500;
This script only successfully uploads images smaller than that (regardless of MB size)
My understanding is that the script should resize the file and put it in the appropriate folder.

It does say that it uploaded successfully, but the file is nowhere to be found on my server.

The upload and the resize are two diff. things (maybe the messages are not clear)
I will check the message, try to upload a file from 800KB and tell if the work fine.

Just checked the messages and the upload functions: everything is fine

maybe there are problems with the chmod values? it's a shared host?

It's a dedicated host, and all upload folders are chmod 777.

I just removed the dimension checking.  I just want to relay on actual filesize anyway.

Thanks

I just want to relay on actual filesize anyway.

what do you mean with that? having max 1MB after Resize?

Yeah, I want it to check for file size in MB, the height and width is not as important, so in "process_image" I changed:

      $this->check_dimensions($filename); // check which size is longer then the max value
      if ($this->larger_curr_value > $this->larger_dim_value) {
         $this->thumbs($filename, $foto, $this->larger_dim_value, $compression);
      } else {
         copy($filename, $foto);
      }

to

      copy($filename, $foto);

you need only an upload functtion? check the regular example...

And don't change the source files otherwise you can't handle the updates later

ok.  Thanks for being so insistant on helping me :-)

Hi, i'm having the exact same problem as one of your notice board users Olaf but the issue was never answered -

I am having some problems with the image resizing feature (foto_upload.php). Evevry time i upload a file it says that uploaded and processed. But i dont see the file(s) in my directory. Interesting thing is when i upload really small images like 150x100 it uploads. But as soon as i use bigger images nothing happens. I've increased the the 1Mb limit on the script upload file and the above issue seems to be resolved but i never get any errors!!!! - lke i thought too that with the foto script, that the images are resized for you aswell?


PLEASEEEEEEEEEEEEEEEE Can you please help me?

Thanks!!
