Showing fields from a query in php - php

Question

I'm new in PHP and i'm having a trouble in showing the retrived data from a query. There area four area_name and many type_name, type_desc and type_price under that area_name
I wanted to display those data in a format like this:
area_name1
type_name1_1
type_desc1_1
type_price1_1
type_name1_2
type_desc1_2
type_price1_2
then
area_name2
type_name2_1
type_desc2_1
type_price2_1
type_name2_2
type_desc2_2
type_price2_2
But in my code, it is displayed like this:
area_name1
type_name1_1
type_desc1_1
type_price1_1
area_name1
type_name1_2
type_desc1_2
type_price1_2
then
area_name2
type_name2_1
type_desc2_1
type_price2_1
area_name2
type_name2_2
type_desc2_2
type_price2_2
Can anyone help me on how to show the area_name once then show the type_names under that specific area_name? any help/assistance will be greatly appreciated.
<?php
include 'config.php';
$query = "select a.area_name,t.type_no,t.type_name,t.type_desc,t.type_price,t.area_no, a.area_no from area as a INNER JOIN type as t where a.area_no=t.area_no";
$stmt= dbConnect()->prepare($query);
$stmt -> execute();
$text_num = $stmt -> rowCount();
?>
<div id="prices_content">
<div>
<?php if ($text_num>0) {?>
<?php while ($row=$stmt->fetch(PDO::FETCH_ASSOC)) {?>
<div id="content">
<br><br><br><center>
<b><h1><?php echo $row['area_name']; ?></h1></b><br>
<p><?php echo $row['type_name']; ?></p><br>
<p><?php echo $row['type_desc']; ?></p><br>
<p><?php echo $row['type_price']; ?></p></center><br>
</div>
<?php }?>
<?php }?>
</div>
</div>

Answer 1

In your while loop you're echoing $row['area_name'] every time. You need to declare a variable outside the loop to hold the area name and check it in each loop to see if it changed.
Like this:
$area_name = '';
<?php while ($row=$stmt->fetch(PDO::FETCH_ASSOC)) {?>
<div id="content">
<br><br><br><center>
<?php if($area_name != $row['area_name']){ ?>
<?php $area_name = $row['area_name']; ?>
<b><h1><?php echo $row['area_name']; ?></h1></b><br>
<?php } ?>
<p><?php echo $row['type_name']; ?></p><br>
<p><?php echo $row['type_desc']; ?></p><br>
<p><?php echo $row['type_price']; ?></p></center><br>
</div>
<?php } ?>

Try this Code,
<?php
include 'config.php';
$query = "select a.area_name,t.type_no,t.type_name,t.type_desc,t.type_price,t.area_no, a.area_no from area as a INNER JOIN type as t where a.area_no=t.area_no";
$stmt= dbConnect()->prepare($query);
$stmt -> execute();
$text_num = $stmt -> rowCount();
?>
<div id="prices_content">
<div>
<?php if ($text_num>0) {?>
<?php while ($row=$stmt->fetch(PDO::FETCH_ASSOC)) {?>
<div id="content">
<br><br><br><center>
<?if($area_name !== $row['area_name']){?>
<b><h1><?php echo $row['area_name']; ?></h1></b><br>
<?php }?>
<p><?php echo $row['type_name']; ?></p><br>
<p><?php echo $row['type_desc']; ?></p><br>
<p><?php echo $row['type_price']; ?></p></center><br>
</div>
<?php $area_name = $row['area_name'];}?>
<?php }?>
</div>
</div>

Answer 3

You are adding the area_name into the loop so it will be displayed
you should try this
<div id="prices_content">
<div>
<?php if ($text_num>0) {?>
<b><h1><?php echo $row['area_name']; ?></h1></b><br><!-- this outside of the loop-->
<?php while ($row=$stmt->fetch(PDO::FETCH_ASSOC)) {?>
<div id="content">
<br><br><br><center>
<p><?php echo $row['type_name']; ?></p><br>
<p><?php echo $row['type_desc']; ?></p><br>
<p><?php echo $row['type_price']; ?></p></center><br>
</div>
<?php }?>
<?php }?>
</div>
