2006/8/7, [EMAIL PROTECTED] <[EMAIL PROTECTED]>:
Hi to all!
I have a form with 6 text fields where visitor has to enter product serial
number (same type data). he has to enter AT LEAST ONE.
for ($i=0; $i<6; $i++)
{
echo '<input type="text" name="PSN['.$i.']" value="'.$PSN[$i].'"
size="25">';
}
After the form is submitted I'm getting an array
Array
(
[0] => abc123
[1] => ddd111
[2] => poi987
[3] =>
[4] =>
[5] =>
)
Now, I need to get rid off empty elements of the array, to get this:
Array
(
[0] => abc123
[1] => ddd111
[2] => poi987
)
To do that I tried:
foreach ($PSN as $value)
{
if (!empty($value)) $PSN_New[] = $value;
}
but every time I'm getting one additional element of the array:
I tried
foreach ($PSN as $value)
{
if ($value != '') $PSN_New[] = $value;
}
too - same result.
Array
(
[0] => abc123
[1] => ddd111
[2] => poi987
[3] =>
)
No space or anything else is "entered" in 4th field.
What I'm doing wrong?
Thanks for any help.

There are probably some whitespaces in the elements which refuse to be
deleted.
Also consider using array_filter() instead of looping through the array
(used without a callback function filter all elements which evaluate to
boolean false).
