Split database: 20 rows a page

[GetAWeapon]

Hello everyone,

 

I new to the php world and I'm only working with it for 5 days now. So I'm a noob

 

But I've got a good start atm, I already could connect a database with my webpage and show all my coloms I need.

 

Now I got a problem with the fact, my database is way to big to display on 1 page. To much load-time, so that's the reason why I want to split up all my products.

20 for each page, like in this tutorial: http://www.phpjabbers.com/php--mysql-select-data-and-split-on-pages-php25.html?err=1

 

I think I'm almost there, my problem is that when I click on the number from the next page (like nr 5), it doesn't show my next 20 products.

But when I look to the url, that seems ok, because I get something like this; index.php?page=1

 

Can someone help me to find out, what I did wrong? And plz, remember, if you give me an answer, plz keep it short and simple. I'm a noob at this.

 

This is my code:

<?php
include('connect-mysql.php');
if (!empty($_GET["page"])) {
    $page  = $_GET["page"];
} else {
    $page=1;
}; 
$start_from = ($page-1) * 20; 
$sqlget = "SELECT *
FROM artikel, images
LIMIT 0, 20
";

$sqldata = mysqli_query($dbcon, $sqlget) or die('error getting');

echo "<table>";
echo "<tr><th>A_ARTCODE</th><th>A_NUMMER</th><th>A_OMSCHRN</th><th>A_REFLEV</th><th>A_WINKEL</th><th>I_ARTCODE</th><th>I_FILE</th></tr>";

while($row = mysqli_fetch_array($sqldata)){
	echo "<tr><td align='right'>";
	echo $row['A_ARTCODE'];
	echo "</td><td align='left'>";
	echo $row['A_NUMMER'];
	echo "</td><td align='left'>";
	echo $row['A_OMSCHRN'];
	echo "</td><td align='left'>";
	echo $row['A_REFLEV'];
	echo "</td><td align='right'>";
	echo $row['A_WINKEL'];
	echo "</td><td align='right'>";
	echo $row['I_ARTCODE'];
	echo "</td><td align='right'>";
	echo $row['I_FILE'];
	//echo "<img src='000000-001000".$row['I_ID']."' />";
	echo "</td></tr>";
	}
	
echo "</table>";

$sql = "SELECT COUNT(A_ARTCODE) FROM artikel";
$rs_result = mysqli_query($dbcon, $sql) or die ("mysqli query dies");
$row = mysqli_fetch_row($rs_result) or die ("mysqli fetch row dies");
$total_records = $row[0];

$total_pages = ceil($total_records / 20);

for ($i=1; $i<=$total_pages; $i++) { 
            echo "<a href='index.php?page=".$i."'>".$i."</a> "; 
};
?>

I hope someone can help me.

Have you tried using the offset created here in the query?

 

$start_from = ($page-1) * 20;

 

The query is currently hard coded to always get the first 20 entries:

 

LIMIT 0, 20

Oooooh yes, ofcourse, why didn't I think of that xD I just needed to replace this:

 

$sqlget = "SELECT *

FROM artikel, images

LIMIT 0, 20

";

 

 

to 

 

 

 

$sqlget = "SELECT *

FROM artikel, images

LIMIT $start_from, 20

";

 

 

Thanks for the fast support, I'm really greatfull, but I also got another question, but I'll guess I better make another topic for it or not?

No problem. 

 

Side note: MySQL doesn't always return results in the same order. If you haven't done so already, you should look into specifying a sort order. More information can be found here:
