Generate title from database and show related post - php

Question

I have a DB name askadoc , where people can ask about their problem. I want to show all question(or you can say the titles) together in a page. And then when user click on a question, the question will show in a different page with it's comments/details. To do this i have tried the below code and its working perfectly. but how can i do it without using button ?
<?php
$comment = "SELECT * FROM `askadoc` ";
$result = mysqli_query($conn, $comment);
$question = "";
$id="";
if(mysqli_num_rows($result)>0){
while($row = mysqli_fetch_assoc($result)) {
$id = $row["id"];
$question = $row["question"];
?>
<form action="post.php" method="post">
<?php
echo $id;
echo "<input type='hidden' name = 'id' value = ".$id.">";
echo "<button>".$question."</button>";
echo "<br>";
?>
</form>
<?php
}
}
?>

Answer 1

I think you don't need form this. You can user anchor like this.
if (mysqli_num_rows($result) > 0) {
while ($row = mysqli_fetch_assoc($result)) {
$id = $row["id"];
$question = $row["question"];
?>
<?php echo $question ?>
<?php
}
}
Now when you click this anchor, you get question id inside post.php, so easily you can display a particular question comments.

Answer 2

You can use anchor tag then pass the question id to post.php
if(mysqli_num_rows($result)>0){
while($row = mysqli_fetch_assoc($result)) {
$id = $row["id"];
$question = $row["question"];
?>
<?php
echo "<a href='post.php?question_id=".$id."' target='_blank'>".$question."</a>";
echo "<br>";
?>
<?php
}
}
Then to get the value of question_id use $_GET['question_id'];
$questionId = $_GET['question_id']
and its better to check if question_id does exist.
$questionID = isset($_GET['question_id'])? $_GET['question_id'] : '';
if(!empty($questionID)){
//Use $questionID here to query some data from database
}
