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.
