I am currently making a quiz system in php. Im currently designing the quiz interface and I am trying to display all the choices for a specific question. My question is how would I select all the choices
with module_id
= 2 and question_id
= 3?. This is my php code:
<?php
require_once 'includes/config.php';
include 'main.php';
$numberQuestions = $_GET['numberQuestions'];
$module = $_GET['module'];
$sqlQuestion = "SELECT * FROM questions WHERE module_id = $module";
$questionResult = mysqli_query($connect, $sqlQuestion);
$question = mysqli_fetch_assoc($questionResult);
$sqlChoices = "SELECT * FROM choice AS C
INNER JOIN questions AS Q ON C.question_id=Q.question_id
WHERE Q.module_id = $module AND C.question_id = $question['question_id']";
$choicesResult = mysqli_query($connect, $sqlChoices);
?>
?>
<div class="wrapper">
<div class="quizContainer">
<div class="current">Question 1 of 5</div>
<p class="question"><?php echo $question['question'];?></p>
<form method="POST" action="process.php">
<div class="choiceContainer">
<ul>
<?php while($row = mysqli_fetch_assoc($choicesResult)): ?>
<li><input name="choice" type="radio" value="<?php echo $row[choice_id];?>"/><?php echo $row['choice'];?></li>
<?php endwhile; ?>
</ul>
</div>
<button type="submit" name="submit">Submit</button>
<input type="hidden" name="numberQuestions" value="<?php echo $numberQuestions; ?>"/>
</form>
</div>
</div>
EDIT: I am getting this error
Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting '-' or identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in C:\xampp\htdocs\Project\quiz.php on line 11
