Grouping Data under Headers - php

Question

Hi guys i currently have a address book that displays the information like this:
Extension Name Department Email Cellphone
1 jurgen home 1# 1
2 dawn work 2# 2
3 mike away 3# 33
Is there a way to display the information by Department? such as this: Where it shows the users under each department that they fall under, basically grouping them? be gentle :) im new to coding :D
Extension Name Email Cellphone
ALPINE DEALER PRINCIPAL
7813 Garth 123#alpinemotors.co.za 2
7898 Sam 3653#alpinemotors.co.za 4
AFTER-SALES DIRECTOR
7709 Bruce 6342#alpinemotors.co.za 3
Heres my code for the view.php page (on a side note i made a search bar but dont know how to code it to search the names field actively, so as they type in the search bar, the tables filter without having to press enter)
default:
$sql ="SELECT * FROM address ORDER BY name ASC";
$data = mysql_query($sql);
?>
<h2>Alpine VW Extension List</h2>
<table class="tableStyleClass">

<th width="100">Extension</th>
<th width="100">Name</th>
<th width="200">Department</th>
<th width="200">Email</th>
<th width="200">Cellphone</th>

(THE ABOVE CODE WAS FIXED FROM ANSWERS BELOW)
Ok now that i have that sorted my edit button doesnt seem to work. it supposed to display the current info and then once edited, you click the edit button and it changes the information for that user.
Here is the code i was using previously:
case 'edit':
?>
<h2>Editing: <?=$_GET['name'];?></h2>
<form name="form1" action="<?=$_SERVER['PHP_SELF'];?>?mode=edited" method="post">
<table width="399" class="tableStyleClassTwo">
<tr><td width="87">Name:</td>
<td width="551"><div align="left">
<input type="text" value="<?=$_GET['name'];?>" name="name" />
</div></td></tr>
<tr><td>Phone:</td><td><div align="left">
<input type="text" value="<?=$_GET['phone'];?>" name="phone" />
</div></td></tr>
<tr><td>Email:</td><td><div align="left">
<input type="text" value="<?=$_GET['email'];?>" name="email" />
</div></td></tr>
<tr><td>Extension:</td><td><div align="left">
<input type="text" value="<?=$_GET['Ext'];?>" name="Ext" />
</div></td></tr>
<tr><td colspan="2" align="center">Back |<input name="Submit" type="submit" value="Save Changes" /></td></tr>
<input type="hidden" name="mode" value="edited">
<input type="hidden" name="id" value="<?=$_GET['id'];?>">
</table>
</form>
<?php
break;
case 'edited':
$name = $_POST['name'];
$phone = $_POST['phone'];
$department = $_POST['department'];
$email = $_POST['email'];
$Ext = $_POST ['Ext'];
$id = $_POST['id'];
$sql = "UPDATE address SET name = '" . $name ."', phone = '" . $phone . "', email = '" . $email . "', Ext = '" . $Ext . "' WHERE id = '" . $id . "'";
mysql_query($sql);
header('location: ' . $_SERVER['PHP_SELF']);
break;

Answer 1

Try this query -
$sql = "SELECT t1.Ext, t1.name, t1.email, t1.cellphone FROM address t1 join address t2 on t1.id=t2.id ORDER BY t2.department";
EDIT:
<?php
$sql = "SELECT t1.Ext, t1.name, t1.email, t1.cellphone FROM address t1 join address t2 on t1.id=t2.id ORDER BY t2.department";
$data = mysql_query($sql);
?>

Answer 2

Here's another way:
$depts = [];
$res = mysql_query("SELECT * FROM address ORDER BY department, name");
// build the appropriate data structure that organizes contacts into different departments
// by looping through each contact, check if department exist (if not create the department) and add contact to the department
while ($row = mysql_fetch_assoc($res)) {
if (!isset($depts[$row['department']])) {
$depts[$row['department']] = [];
}
$depts[$row['department']][] = $row;
}
?>

<table class="tableStyleClass">

<th width="100">Extension</th>
<th width="100">Name</th>
<th width="200">Email</th>
<th width="200">Cellphone</th>
<th width="200" colspan="2">Admin</th>
</tr>
<tr>
<td colspan="6">
<?php if ($disable != 1) : ?>
Add Contact
<?php else : ?>
<span>Contact Book is Full</span>
<?php endif ?>
</td>
</tr>
<?php foreach ($depts as $dname => $contacts) : ?>
<tr>
<td colspan="6"><?= $dname ?></td>
</tr>
<?php foreach ($contacts as $contact) : ?>
<tr>
<td><?= $contact['ext'] ?></td>

<?php endforeach ?>
<?php endforeach ?>

On another note, stop using mysql_* functions. There's a big red warning that says it is deprecated for good reasons. Use mysqli or better PDO instead!
And make better use of CSS (and use less attributes such as align="right"). You can use :nth-child selector (particularly with :even and :odd)to do your alternating styles for your table.
