Build Upload File Fields On The Fly??

kpowning

I'm wondering if anyone knows how or even if it is possible to show a certain amount of file upload fields in a form pending the an amount I want to give a user to upload. I have a database where I want to save a cell called "amtupload" and here I want the form to check how many fields to give the user.

Example: User = Susie, amtupload = 3

So there would be 3 file upload fields on the form for this user and so on if the amtupload = 4, 5, 6, 7 & 8.

Also once I get this I need it to check how many files are already uploaded and if say for instance they only uploaded one file they should have 2 file upload fields in the form until they decide to upload the other 2 at anytime.

I'm Really stuck on this, so if anyone can help me thank you in advance. Also any examples would be greatly appreciated.

Hi,

To check the number of files:

Have a table with records for each upload, storing e.g., the userid and the file information (name, path, date upload ..). Query this table for the number of files present and match this against the permitted number of files.

To have multiple file uploads.. What it the problem you are facing here? You can just place as many file upload fields in your form as you'd like. If you name the formfields like: name="file[]" you wikll automatically create an array of uploaded files in your $_FILES array.

Use
echo "<pre>";
print_r($_FILES);
echo "</pre>";
in your processing script to view the structure of this array.

Thanks for the response. Yes, this is the route im going for, I have 8 file[] fields that are exactly that an array, but say the user uploads 2 images successfully and I'm only allowing them to upload a total of 8 images, then I only want 6 upload fields to remain for the user to select an image in. I hope this makes sense..

How can I integrate this?

As said before:
Have a table with records for each upload, storing e.g., the userid and the file information (name, path, date upload ..). Query this table for the number of files present and match this against the permitted number of files.

If you use a for() or a while() loop to echo out the file upload fields, this will give you the option to limit the loop to a specific number of fields.

$i = // Get current number from your database
while($i < $maxNumberOfFiles)
  {
  echo "<input type=...";
  $i++;
  }
