Foreach $_POST

Hi,

I have several fields in my form which i want to loop through. I want to add them all to a variable separated by a : but there is one field i do not want to be added which is called red.

So need something like this but how would i stop it adding the field called red?

$new .= $_GET['id'];
							
				foreach($_POST as $post) {
                	$new .= .":".$_POST[$post];
				}
				
				$new .= .',';

PHP:

Also do you notice anything incorrect with the above as this does not work and just goes to a blank page.

Cheers,
Adam

 

I'm not sure what your sending through your post (if it's an array or what have you) but try this:

$new .= $_GET['id'];
                            
                foreach($_POST as $post => $val) {
                    $new .= ":".$val.",";
                }

To exclude a field called red:

$new .= $_GET['id'];
                          
foreach ($_POST as $post => $val) {
  if ($post != 'red') {
    $new .= ':' . $val;
  }
}

$new .= ',';

PHP:

 

It would be better to simply do this before entering the foreach:-

unset($_POST['red']);

PHP:

This is more efficient and saves a test/comparison for each element. Removing the 'red' field is now of O(1) rather than O(n).

 

True. Admitted that he won't need it later on.
Of course, if that's the case, he might just save it in a variable, and then delete it from the $_POST array.
