pass a jquery variable to php code - php

Question

this is my php code
require 'functions/connection.php';
$conn = Connect();
$result = mysqli_query($conn,"SELECT * FROM employee ORDER BY id asc");
echo "
<tr>
<th>Id</th>
<th>First name</th>
<th>Last name</th>
<th>Salary</th>
<th>Start Date</th>
<th>Department</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>" . $row['firstname'] . "</td>";
echo "<td>" . $row['lastname'] . "</td>";
echo "<td>" . $row['salary'] . "</td>";
echo "<td>" . $row['startdate'] . "</td>";
echo "<td>" . $row['department'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($conn);
?>
and this is my jquery code
<script>
$('.sort').click(function(){
var value = $(this).attr('data-val');
var field_name = $(this).attr('data-field');
$.post( "getEmployee.php", {value:value, field_name:field_name}, function( data ) {
$('.responstable').html(data);
});
if(value=="asc"){
$x="asc";
}
else{
$x="desc";
}
});
</script>
i would like to pass the variable x from the jquery code to the php so i can order my database asc or desc like this:
result = mysqli_query($conn,"SELECT * FROM employee ORDER BY id $x");

Answer 1

In your jquery code
$.post( "getEmployee.php", { sort: "asc" } );
In your php code using
$_POST['sort']
