What is wrong with this code

[Anon]

<?

	   session_unregister ($ses_name[$position]);
	   session_unregister ($ses_amount[$position]);
	   session_unregister ($ses_price[$position]);
	   session_unregister ($ses_id[$position]);
	   session_unregister ($ses_des[$position]);
	   session_unregister ($ses_ship[$position]);
	   session_unregister ($ses_items[$position]);

?>

The code above is what I am trying to use to delete a sessions var. for some reason it will not work worth a lick.

I have two pages one page loads the item into the session with a link to keep on searching or view what they have in the carte. I also have a link in the view carte page that says delete/remove. The link would look like this
http://www.someting.com/delete.php?position=0

of course I will get the positon value from when I loop through the session. So on the delete page I have the code above. Once it runs, I get no errors at all, I go back to the view page to make sure that the item was indeed moved. I find it is not 🙁

So any ideas about what I am doing wrong?

Thanks for you help in advance!!

Cheers!

Hi Stephen,

the function session_unregister() takes a string as a parameter. What probably goes wrong is that you want to unregister the variable $ses_name[$position]).
To do this, use the following line:
session unregister("ses_name $position]");

This should work. I hope it helps you.

Good luck,

$ses_name[$position]

that's not a var, it's an element in an array.

Thus you can't unregister it, but you can unset it.

unset($ses_name[$position])

then $ses_name will continue to exist, but element $position is erased.

ok but I want to get rid of all the values in that position as well as the spot in the array. For this I need to use the session unregister function right?

The above post has this code
session unregister("ses_name $position]");
Is that right?

Could you maybe show me some line of code to do this. Maybe just load two things into a session and then show me how to unregister one?

Sorry for not gabbing this info. faster guys

How can I stop the $ses_name from existing or... what could I use to display what is in the session with out showing the ones that are empty.

Here is some code that I got to work but it wipes all the informatoin out ;( any ideas why?

for ($ses_basket_items=0;$position==$ses_basket_items;$ses_basket_items++){

	   session_unregister($ses_basket_name [$ses_basket_items]); 
	   session_unregister ($ses_basket_amount[$ses_basket_items]);
	   session_unregister ($ses_basket_price [$ses_basket_items]);
	   session_unregister ($ses_basket_id [$ses_basket_items]);
	   session_unregister ($ses_basket_des [$ses_basket_items]);
	   session_unregister ($ses_basket_ship [$ses_basket_items]);
	  // session_unregister ($ses_basket_items [$ses_basket_items]);

}

If you want to erase the entire $ses_name, then you should use
session_unregister('ses_name');
that will destroy the entire array.

Just use session_unregister('name_of_var');

the point is: You can only unregister COMPLETE vars, not elements of an array, not properties of an object, only complete vars.

How many times do I have to tell you that this is not allowed?

session_unregister ($ses_basket_des [$ses_basket_items]);
