Pass multiple dynamic arrays to php some hidden - php

Question

I received help already with a previous question about posting an array.
Now I'm trying to add more arrays to the loop
Here's the html
<input class="input stickyinput" type="number" name="pestcount[]">
<input type="hidden" name="cardtype[]" value="<?= htmlspecialchars($obj['cardtype']) ?>" />
<input type="hidden" name="cardid[]" value="<?= htmlspecialchars($obj['card_id']) ?>" />
<input type="hidden" name="pestname[]" value="<?= htmlspecialchars($pestname['scoutlogpestname']) ?>" />
Here's the php
for ($i=0; $i < count($_POST['cardid']); $i++ ) {
$card_id = $_POST['cardid'][$i];
$card_type = $_POST['cardtype'][$i];
$pest_count = $_POST['pestcount'][$i];
$pest_name = $_POST['pestname'][$i];
$sql ="INSERT INTO scout_logpestnum (pest_name,pest_count,card_id,card_type)
VALUES (:pest_name,:pest_count,:card_id,:card_type)";
$q = $pdo->prepare($sql);
$q->execute(array(':pest_name'=>$pest_name,':pest_count'=>$pest_count,':card_id'=>$card_id,':card_type'=>$card_type));
}
So what is the proper format for adding addition arrays from the form?. Thanks;)
Here's what my array looks like.
Array (
[pestcount] => Array (
[0] => 1
[1] => 2
[2] => 3
)
[cardtype] => Array (
[yellcard] =>
)
[cardid] => Array (
[1] =>
)
[pestname] => Array (
[Aphids] =>
[Thrips] =>
[White-Fly] =>
)

Assuming that pests and cards are separate collections, you can simply use a prefix to identify them in $_POST data. For example...
<input name="pests[<?= htmlspecialchars($pestname['scoutlogpestname']) ?>][<?= $obj['card_id'] ?>]" ...
and
<input name="cards[<?= htmlspecialchars($obj['cardtype']) ?>][<?= $obj['card_id'] ?>]" ...
This would produce HTML like
<input name="pests[Aphids][1]" ...
<input name="cards[yellcard][1]" ...
Then, in your form handler...
$pests = $_POST['pests'];
foreach ($pests as $pest_name => $values) {
foreach ($values as $card_id => $pest_count) {
echo $pest_name, $card_id, $pest_count;
}
}
$cards = $_POST['cards'];
foreach ($cards as $card_type => $values) {
foreach ($values as $card_id => $value) {
echo $card_type, $card_id, $value;
}
}
