PHP - Automatic Upload

Hi everyone,

I have a page that i use to upload images to my website, i got a bit fed up of uploading one at a time so i decided to add multiple file fields to the form to upload multiple images at the same time.

Im having a few problems, iv read up he http://www.php.net/manual/en/features.file-upload.multiple.php and it seems all i have to do is add [] to the form names to turn them into arrays. However when i come to upload the images, i keep getting the "$error[] = "Incorrect format!...." error from the code below. I cant seem to figure out what the problem is.

Could anybody please point me in the right direction?

I have code written for image uploading, but it doesn't allow multiple images on a single upload, and doesn't re-size.

Anyone willing to share a good upload script that will do the following?:
-Allow multiple image uploads (10+ per submission),
-Re-size images on upload, and
-Rename images.

Thanks

Hi!

I have a question that I need help with.
I guess almost everyone of us have played a webgame where something happends automaticly.
Some examples:
Attacks, resources in Travian, Tribalwars, Khan Wars ...

How are these things done?
Now I'm talking about automatical things that happends every second.
Is there a Cron Job that every second connectes to a database and adds more resources to the player?

Regards

<?php
$files=glob('apk/*');
foreach( $files as $file)
{ echo '<img scr="'.$file.'">'.basename($file).'</img><br/>';

}

?>

I'm trying to create a table that looks like this:

25/11/2011 28/09/2012 02/08/2013 23/12/2011 26/10/2012 30/08/2013 20/01/2012 23/11/2012 27/09/2013 17/02/2012 21/12/2012 25/10/2013 16/03/2012 18/01/2013 22/11/2013 13/04/2012 15/02/2013 20/12/2013 11/05/2012 15/03/2013 17/01/2014 08/06/2012 12/04/2013 14/02/2014 06/07/2012 10/05/2013 14/03/2014 03/08/2012 07/06/2013 11/04/2014 31/08/2012 05/07/2013 09/05/2014
Basically it formats the dates automatically every 4 weeks into 3 columns. So far, I have the following code:

Code: [Select]
<?php
$startDate = '2011-11-25';
$columns = 3;
$number_of_dates = 33;

// calculate number of rows per column
$rows_per_column = ceil($number_of_dates / $columns);
// make your table
echo "<table>\n";

//here we changed the condition to $i < $rows
for($i = 0; $i < $rows_per_column; $i++) {

echo "<tr>\n";

//here will run another loop for the amount of columns
for($j = 0; $j < $columns; $j++) 
{
$weekOffset = $i * 4;
     $nextDate = strtotime("{$startDate} +{$weekOffset} weeks");
     echo "<td width = '100'>" . date('d/m/y', $nextDate) . "</td>\n";
    }
echo "</tr>\n";
}
echo "</table>\n";
?>

Which creates the first column fine, but then repeats the same column two more times...

25/11/2011 25/11/2011 25/11/2011 23/12/2011 23/12/2011 23/12/2011 20/01/2012 20/01/2012 20/01/2012 17/02/2012 17/02/2012 17/02/2012 16/03/2012 16/03/2012 16/03/2012 13/04/2012 13/04/2012 13/04/2012 11/05/2012 11/05/2012 11/05/2012 08/06/2012 08/06/2012 08/06/2012 06/07/2012 06/07/2012 06/07/2012 03/08/2012 03/08/2012 03/08/2012 31/08/2012 31/08/2012 31/08/2012
I know that this means there is a problem with my loop resetting itself rather than continuing, but I'm not sure how to fix it. Please could someone point out my stupid mistake?

Thanks
