I am trying to insert values input from the user in a form into my database.
I have 2 drop down lists for a blood test and then category. E.g user first selects drop down 1 'Thyroid' (Category) and then drop down 2 displays 'FT4,FT3 TSH' (blood test) etc and the user makes their selection.
Then they input the date and the value.
In my insert I need to insert into my database the user_id(established after login with session variables, bloodtest_id(from drop down 2), date, value.
I can't get my SQL query right for the insert in general and need some help please. Drop down 2 (blood test) is in a seperate php file and I'm not sure how to tell the SQL query how to find that value to use either?
The addBlood.php is below. This is the page the form is on
<?php
session_start();
include('dbConnect.php');
$queryStr=("SELECT * FROM category");
$dbParams=array();
// now send the query
$results = $db->prepare($queryStr);
$results->execute($dbParams);
?>
<html>
<head>
<TITLE>Category and Test</TITLE>

<script src="https://code.jquery.com/jquery-2.1.1.min.js" type="text/javascript"></script>

function getTest(val) {
$.ajax({
type: "POST",
url: "get_test.php",
data:'category_id='+val,
success: function(data){
$("#test-list").html(data);
}
});
}
function selectCategory(val) {

<?php
if(isset($_POST['submit'])){
//$currentBloodTest=$test["bloodtest_id"];
$currentUser=$_SESSION["currentUserID"];
$value = $_POST['result'];
$date = $_POST['date'];
//$query = $db->prepare("INSERT INTO results (user_id, bloodtest_id,date,value)values ($currentUser,$currentBloodTest, $date , $value)");
$dbParams = array();
$query->execute($dbParams);
echo "<br><br><span>Data Inserted successfully...!!</span>";
}
?>
</body>

Below is the getTest.php which gets all the blood tests.
<?php
include('dbConnect.php');
if(!empty($_POST["category_id"])) {
$queryStr=("SELECT * FROM bloodtests WHERE category_id = '" . $_POST["category_id"] . "'");
$dbParams=array();
// now send the query
$results = $db->prepare($queryStr);
$results->execute($dbParams);
?>
<option value="">Select Test</option>
<?php
foreach($results as $test) {
?>
<option value="<?php echo $test["bloodtest_id"]; ?>"><?php echo $test["test_name"]; ?></option>
<?php
}
}
?>

Also, this part you have in the ajax lookup:
