How do i skip a $_FILES in a form post?

[JJohnsenDK]

Hey

 

Im wondering how i skip the $_FILES part in a form post. I need this because its not every time i need to submit with a picture in my form.

 

Here is the code im using:

 

<?php
foreach($_FILES['image']['error'] as $k => $error){

					//Tjekker for fejl, hvis igen gå videre
					if($_FILES['image'][$k][$error] == 0){

						//Tjekker om billedet er et gyldigt billede. JPEG eller GIF billede.
						if($_FILES['image']['error'][$k] == "image/jpeg" || $_FILES['image']['error'][$k] == "image/pjpeg" || $_FILES['image']['error'][$k] == "image/gif"){

							if(!empty($_FILES['image']['name'][$k])){
								if(empty($_POST['order'])){
									echo "Du skal vælge hvilket nr. billedet skal være. 1, 2 eller 3.";
								}else{
									//Kopier billedet over i den angivne mappe
									copy($_FILES['image']['tmp_name'][$k], "images/products/".strtolower(get_type_name($_POST['type']))."/".strtolower(get_cat_name($_POST['cat']))."/".$_FILES['image']['name'][$k]."");
									echo $lan['007'].$_FILES['image']['name'][$k];
}
							}
						}else{
							echo "Billedet skal være et JPEG billede.";
						}
					}else{
						echo "Der skete en fejl da billedet skulle uploades. Prøv igen.";
					}
?>

 

I thougth i could do this:

if(empty($_FILES['image']['name'])){

  then skip the hole foreach part

}

 

but this didnt help.

 

What to do??

What type of form is it?

 

If it's like a post where there is a box to post the image URL, then you can just set up an if statement.

 

<form action='$_SERVER['PHP_SELF']' method='post'>
  <input type='text' size='20' name='picURL' />
</form>
<?php

$picURL = $_POST['picURL'];
if ($picURL)
   // code to upload pic
else
   // exit

?>

 

Something like that?

<?php


if($_FILES['image']==NULL)
{
foreach($_FILES['image']['error'] as $k => $error){

					//Tjekker for fejl, hvis igen gå videre
					if($_FILES['image'][$k][$error] == 0){

						//Tjekker om billedet er et gyldigt billede. JPEG eller GIF billede.
						if($_FILES['image']['error'][$k] == "image/jpeg" || $_FILES['image']['error'][$k] == "image/pjpeg" || $_FILES['image']['error'][$k] == "image/gif"){

							if(!empty($_FILES['image']['name'][$k])){
								if(empty($_POST['order'])){
									echo "Du skal vælge hvilket nr. billedet skal være. 1, 2 eller 3.";
								}else{
									//Kopier billedet over i den angivne mappe
									copy($_FILES['image']['tmp_name'][$k], "images/products/".strtolower(get_type_name($_POST['type']))."/".strtolower(get_cat_name($_POST['cat']))."/".$_FILES['image']['name'][$k]."");
									echo $lan['007'].$_FILES['image']['name'][$k];
}
							}
						}else{
							echo "Billedet skal være et JPEG billede.";
						}
					}else{
						echo "Der skete en fejl da billedet skulle uploades. Prøv igen.";
					}

}
?>

 

 

This should work, but with no real way to test (and my poor german skills, lol), I can't be entirley sure...no reason why it won't though.
