How to compare value of a dynamically created radio button - php

Question

I am dynamically generating a set of radio buttons from MySQL. The buttons are creating and the variables assigned to them are populating as I did an echo print_r and it shows the array for the variable. I now want to compare the values generated from this and if the vale is "0" I want to insert a score and present a green check graphic and the word correct. If the value is "1" I want it to input different values for the score and present Incorrect and a red X graphic. Here is what I have so far (Everything populates dynamically both the question and the answers as radio buttons):
<?php
echo '<form id="frmQuestion" name="frmQuestion" method="post" action="QuizQuestion1.php">';
// Connect to the Database
require_once('mysqli_connect.php');
//create the query for the question
$q = "SELECT `Question` FROM tbl_Question WHERE QuestionID = 1";
//Create the query for the Answers
$q2 = "SELECT `Answer`,`AnswerStatusID`,`AnswerResponse` FROM tbl_Answer WHERE QuestionID = 1";
//Run the query
$r = mysqli_query($conn,$q);
//run the answer query
$r2 = mysqli_query($conn,$q2);
while($row = mysqli_fetch_array($r,MYSQLI_ASSOC)){
echo '<div id="Question1"><p> ' . $row['Question'] . '</div></p>';
}
//Declare the variables as a array
$AnswerResponse = array();
$AnswerStatusID = array();
while($row2 = mysqli_fetch_array($r2,MYSQLI_ASSOC)){
echo '<div id="Question1"><input name="q1" type="radio" value="'.$AnswerStatusID.'"/>' . $row2['Answer'] . '</div><br/>';
//Assign the AnswerStatusID to a var
$AnswerStatusID[] = $row2['AnswerStatusID'];
//Assign the AnswerResponse to a var
$AnswerResponse[] = $row2['AnswerResponse'];
}
//Create the submit button
echo '<input type="submit" value="Submit Answer" name="submit"/>';
echo '</form>';
//Logic for correct or incorrect answers
if (isset($_POST['q1']) && ($_POST['q1'] == '0'))
{
//create the query for the score
$q3 = "INSERT INTO tbl_Score (`Score`,`QuestionID`) VALUES ('100%','1')";
//Run the query
$r = #mysqli_query ($conn,$q3);
if($r){
//Confirm message data was entered with a correct response and a graphic
echo '<h1>Correct!!</h1><img src="/images/green_Check_Low.jpg" alt="Green Check"/>';
echo 'Click here for the next question';
}
else
{
//there was an error
echo'<h1>System error</h1>';
//Debugging message
echo'<p>' . mysqli_error($conn) . '<br/><br/>Query:' . $q3 . '</p>';
}//End of nested IF
}
else{
//create the query for the score
$q4 = "INSERT INTO tbl_Score (`Score`,`QuestionID`) VALUES ('0%','1')";
//Run the query
$r2 = #mysqli_query ($conn,$q3);
if($r2){
//Confirm message data was entered with a correct response and a graphic
echo '<h1>Incorrect!!</h1><img src="/images/red_X_Low.jpg" alt="Red X"/>';
echo 'Click here for the next question';
}
else
{
//there was an error
echo'<h1>System error</h1>';
//Debugging message
echo'<p>' . mysqli_error($conn) . '<br/><br/>Query:' . $q3 . '</p>';
}//End of nested IF
}
//Free up the results for the Question query
mysqli_free_result($r);
//Free up the results from the Answer query
mysqli_free_result($r2);
//close the DB connection
mysqli_close($conn);
?>

Answer 1

This is the answer and work as intended. Thanks for everyones input.
//Declare the variables as a array
$AnswerResponse = array();
$AnswerStatusID = array();
while($row2 = mysqli_fetch_array($r2,MYSQLI_ASSOC)){
echo '<div id="Question1"><input name="q1" type="radio" value="'.$row2['AnswerStatusID'].'"/>' . $row2['Answer'] . '</div><br/>';
//Assign the AnswerStatusID to a var
$AnswerStatusID[] = $row2['AnswerStatusID'];
//Assign the AnswerResponse to a var
$AnswerResponse[] = $row2['AnswerResponse'];
}
//Create the submit button
echo '<input type="submit" value="Submit Answer" name="submit"/>';
echo '<input type="hidden"name="submitted"value="TRUE"/>';
echo '</form>';
if($_POST['submitted']) {
//Logic for correct or incorrect answers
if (isset($_POST['q1']) && ($_POST['q1'] == '0'))
{
//create the query for the score
$q3 = "INSERT INTO tbl_Score (`Score`,`QuestionID`) VALUES ('100%','1')";
//Run the query
$r3 = #mysqli_query ($conn,$q3);
//Confirm message data was entered with a correct response and a graphic
echo '<h1>Correct!!</h1><img src="/images/green_Check_Low.jpg" alt="Green Check"/>';
echo 'Click here for the next question';
}
else{
//create the query for the score
$q4 = "INSERT INTO tbl_Score (`Score`,`QuestionID`) VALUES ('0%','1')";
//Run the query
$r4 = #mysqli_query ($conn,$q4);
//Confirm message data was entered with a correct response and a graphic
echo '<h1>Incorrect!!</h1><img src="/images/red_X_Low.jpg" alt="Red X"/><br/>';
echo 'Click here to try again';
}
}
