Warning: Variable passed to each()

garfx

I am getting this error - it was work fine but i have just swapped server and now the following error message is appearing:

Warning: Variable passed to each() is not an array or object in /content/DesignerPlus/p/r/promo-direct.co.uk/web/admin/order/add.php on line 54

line 54:

while (list($key, $val) = each($_POST[remove])) {

$query = "	DELETE FROM promo_items 
			WHERE id = '$val'
			";
$result = mysql_query($query) or die ("Error in query: $query. " . mysql_error());

}

html:
<input type="checkbox" name="remove[]" value="<?php echo $rowBasket->iid ; ?>" />

please help thank you

you can do all of your deletes in a single query rather than looping through the array:

$result = mysql_query('DELETE FROM promo_items WHERE id IN(' . implode(',', $_POST['remove']) . ')') or exit(mysql_error());

And if you get any more warnings about $_POST['remove'] not being an array, try doing a [man]var_dump/man on it to see what type of variable it is.

apparently the installation on the new server is configured to warn if you try to do something with the wrong datatype. (I suppose in this case $_POST['remove'] is empty, ie. NULL.)

a quick fix:

if(is_array($_POST['remove']))
{
 while (list($key, $val) = each($_POST[remove]))
 ...
}

thank you I've got it working. but now I'm having a similar problem with all my unlink() the error message telling me...

Warning: unlink() [function.unlink]: No such file or directory in.....

code:

unlink($imgfile);

where $imgfile is passed from file field.

please help.

you need to pass the full path to [man]unlink[/man], not just the filename
