I pass that two array data from jquery to php, i need check if the field is empty by php and exit when find one of them is empty.
But i dont want do it one by one, can it done by php function like foreach or other?
This is what i tried but fail.
$data_one = $_POST['one'];
$data_two = $_POST['two'];
if (empty( $_POST['one'] )) { // i only need check `$data_one` in this example
exit('some field are empty');
} else {
echo('field are filled');
// continue other function
}
Above code keep return field are filled message, whether i fill the input field or not.
Thanks so much.

$allFilled = true;
foreach($_POST['one'] as $key=>$value){
if(empty($value)){
$allFilled = false;
exit('some fields are empty');
}
}
if($allFilled){
exit('all fields are filled');
}

Making use of array_filter and count functions
<?php
$data_one = $_POST['one'];
$data_one_filter = array_filter($_POST['one']); //Remove indexes of null or 0 - certainly name and email can't be 0
$data_one_count = count($_POST['one']); //count actual number of POST variables
$data_two = $_POST['two'];
if (count($data_one_filter) === $data_one_count) {
exit('fields are filled');
} else {
echo('some fields are empty');
// continue other function
}

You are sending data as array. So you seed to check this data as array like this:
$data_one = $_POST['one']['name'];
$data_two = $_POST['two']['message'];
if (empty( $_POST['one']['name'] )) { // i only need check `$data_one` in this example
exit('some field are empty');
} else {
echo('field are filled');
// continue other function
}

Try this
foreach($_POST['one'] as $key=>$value){
if(empty($value)){
exit('some field are empty');
}
}
echo "All fields are filled";
