1) You missed name attribute into your automatically generated dropdown list so without name attribute you will not get data into php script.
2) Your newly generated text box name = testparameters[] which array so you can't get value just using $_POST['testparameters']. TO get value, you have to loop through array.
foreach($_POST['testparameters'] as $value) {
// here , you get dynamically added texbox values.
}

Again try loop also but still value cant be stored into cant not count drop down list value & & testparameters textbox save Array keyword what i Try Here is My code:
<?php
include_once "dTestCreation.php";
if(isset($_POST['submit'])) //when clikc on submit button
{
$Testcode = $_POST['testcode'];
$TestName = $_POST['testname'];
$Testparameter = $_POST['testparameters'];
$Instrumentcode = $_POST['instrument_code'];
$InsertQuery = "INSERT INTO demo_test(testcode,testname) VALUES('$Testcode','$TestName')"; //query for insert data into table
$oMysqli=getConnection(); //establish connection
$oMysqli->query($InsertQuery);
//print_r($InsertQuery);exit();
$length = count($_POST['testparameters']);
for($i=0;$i<$length;$i++)
{
//echo $_POST['testparameters'][$i];
$a = $_POST['testparameters'][$i];
$na = array('testparameters' => $a['testparameters']);
foreach($na as $k => $v)
{
$na[$k] = mysql_real_escape_string($v);
}
$TestParameters = $na['testparameters'];
//$TestParameters = $_POST['testparameters'][$i];
$InsertQuery1 = "INSERT INTO test_table(testcode,testparameters,instrument_code) VALUES('$Testcode','$Testparameter','$Instrumentcode')"; //query for insert data into table
$oMysqli=getConnection(); //establish connection
$oMysqli->query($InsertQuery1);
}
}
?>
