Ordering Columns in DDBB Search Results - The Basic Code (
Page 3 of 6 )
Let's write the basic code: it will retrieve the products from the database and display them in a table.
<?
//Connect to the database
$conn=mysql_connect('localhost','root','') or die
('Sorry, no connection to database available :-(');
//Perform our query
$query='SELECT * FROM test.products';
if (!$res=mysql_query($query, $conn))
{
die ('Sorry, query error');
}
//We populate the $output variable with the HTML code
//to generate the results table
$output='<table><tr style="font-
weight:bold"><td>ID</td><td>NAME</td><td>PRICE</td><td>
CODE</td>
<td>WEIGHT</td></tr>';
while ($a=mysql_fetch_row($res))
{
//Append the table row to our $output variable
$output.="<tr id='line$a[0]'><td>$a[0]</td><td>$a[1]
</td><td>$a[2]</td><td>$a[3]</td><td>$a[4]</td></tr>";
}
$output.='</table>';
?>
<html>
<head>
</head>
<body>
<div id='content'>
<?=$output?>
</div>
</body>
</html>
Okay, this piece of code should produce this output, a table with all the products on it:
Make sure you check the while loop. We assign each TR element an id, being this id the ID number of the product (the ID number of each product is unique, so we are sure there won't be two TR with the same ID):
<tr id='line1'><td>1</td><td>Absolute
Delight</td><td>2.20</td><td>59</td><td>50</td></tr>
<tr id='line2'><td>2</td><td>Aqua
Mirabilis</td><td>2.35</td><td>114</td><td>15</td></tr>
This table is then echoed into a DIV element, which I've assigned the id "content".
I can hear you saying "Yes I know where you want to go!" Not really? Ok, flip the page and let's get our hands dirty with the sorting!
