Hi. Hoping someone can explain this to me please.
$quantity = $_POST['quantity'];
echo "<pre> -- quantity -- ";
print_r($quantity);
echo "</pre>";
This returns:
-- quantity --Array
(
[0] =>
[1] =>
[2] =>
[3] => 2
[4] =>
[5] =>
[6] =>
)
$selectitem = $_POST['selectitem'];
echo "<pre> -- selectitem -- ";
print_r($selectitem);
echo "</pre>";
This returns:
-- selectitem --Array
(
[0] =>
[1] =>
[2] =>
[3] => ABC123 - Plain wood
[4] =>
[5] =>
[6] =>
)
$linedetail=array_combine($quantity, $selectitem);
echo "<pre> -- linedetail -- ";
print_r($linedetail);
echo "</pre>";
This returns:
-- linedetail --Array
(
[] =>
[2] => ABC123 - Plain wood
)
Which then in turn causes a warning notice in the following:
foreach ($linedetail as $key => $keyvalue){
$detail = explode(' - ',$keyvalue);
echo "<pre> -- detail -- ";
print_r($detail);
echo "</pre>";
$code = trim($detail[0]);
$item = $detail[1];
}
This returns:
-- detail --Array
(
[0] =>
)
Warning: Undefined array key 1 in ... etc.
-- detail --Array
(
[0] => ABC123
[1] => Plain wood
)
So my question is why is a blank element being created in
-- linedetail --Array
(
[] =>
[2] => ABC123 - Plain wood
)
and how can I avoid it from happening?
