Do your results need to be returned as columns/rows like that? It is much easier to return the details as rows and columns instead (also, more legible in my experience.)

[U][B]id | data[/U][/B]
10 | k
 9 | a
 8 | s

If you are looking to do something like this, use the following code.

<?php 
include "db.php";

//Rows
$qtyRow = '<tr>';
$priceRow = '<tr>';
  
$nn=3; //Number of items

$s=mysql_query("SELECT * FROM `test1`");

$c=mysql_num_rows($s);

if($c%$nn==0){
	$cc=$c/$nn;	
}else{
	$cc=$c/$nn+1;	
}

//$cc : Number of pages

$ss=@$_REQUEST['ss']; //Start position (eg: 3)
$other_tables = "";

if($ss=="" || $ss==null){  //First page
	$sql=mysql_query("SELECT * FROM `test1` ORDER BY `id` DESC LIMIT 3");
	while($r=mysql_fetch_array($sql)){
		$id=$r['id'];  
		$name=$r['name'];
		$qtyRow .= "<td>$id</td>";
		$priceRow .= "<td>$name</td>";
	}
}else{ //Other pages
	$sql=mysql_query("SELECT * FROM `test1` ORDER BY `id` DESC LIMIT $ss,3");
	while($r=mysql_fetch_array($sql)){
		$id=$r['id'];  
		$name=$r['name'];
		$qtyRow .= "<td>$id</td>";
		$priceRow .= "<td>$name</td>";
	}
	
	//Get other results
	$ss = $ss - 3;
	while($ss >= 0){
		$other_tables .= "<br><table border='1' align='center'>";
		$other_qty = "<tr>";
		$other_price = "<tr>";
		$sql=mysql_query("SELECT * FROM `test1` ORDER BY `id` DESC LIMIT $ss,3");
		while($r=mysql_fetch_array($sql)){
			$id=$r['id'];  
			$name=$r['name'];
			$other_qty .= "<td>$id</td>";
			$other_price .= "<td>$name</td>";
		}
		$other_qty .= "</tr>";
		$other_price .= "</tr>";
		$other_tables .= $other_qty . $other_price;
		$other_tables .= "</table>";
		$ss = $ss - 3;
	}
} 
// end of the rows
$qtyRow .= '</tr>';
$priceRow .= '</tr>';
// echo the table
echo "<table border=\"1\" align=\"center\">";
echo $qtyRow;
echo $priceRow;
echo "</table>";
echo $other_tables;
echo "</p>";  //No idea why this is here
$j=0;
echo"page : ";
for($i=1;$i<=$cc;$i++){
	echo"<a href=\"select.php?ss=$j\">$i</a>";
	echo"|";
	$j=$j+$nn; 
}
?>

The change on the sample page I showed you is reflected to match this code:

(Which I think is what you want)

<?php 
include "db.php";

//Rows
$qtyRow = '<tr>';
$priceRow = '<tr>';
  
$nn=3; //Number of items

$s=mysql_query("SELECT * FROM `test1`");

$c=mysql_num_rows($s);

if($c%$nn==0){
	$cc=$c/$nn;	
}else{
	$cc=$c/$nn+1;	
}

//$cc : Number of pages

$ss=@$_REQUEST['ss']; //Start position (eg: 3)
$other_tables = "";

if($ss=="" || $ss==null || $ss==0){  //First page
	$sql=mysql_query("SELECT * FROM `test1` ORDER BY `id` DESC LIMIT 3");
	while($r=mysql_fetch_array($sql)){
		$id=$r['id'];  
		$name=$r['name'];
		$qtyRow .= "<td>$id</td>";
		$priceRow .= "<td>$name</td>";
	}
}else{ //Other pages
	$sql=mysql_query("SELECT * FROM `test1` ORDER BY `id` DESC LIMIT $ss,3");
	while($r=mysql_fetch_array($sql)){
		$id=$r['id'];  
		$name=$r['name'];
		$qtyRow .= "<td>$id</td>";
		$priceRow .= "<td>$name</td>";
	}
	
	//Get other results
	$ss = $ss - 3;
	$other_tables .= "<br><table border='1' align='center'>";
	$other_qty = "<tr>";
	$other_price = "<tr>";
	$sql=mysql_query("SELECT * FROM `test1` ORDER BY `id` DESC LIMIT $ss,3");
	while($r=mysql_fetch_array($sql)){
		$id=$r['id'];  
		$name=$r['name'];
		$other_qty .= "<td>$id</td>";
		$other_price .= "<td>$name</td>";
	}
	$other_qty .= "</tr>";
	$other_price .= "</tr>";
	$other_tables .= $other_qty . $other_price;
	$other_tables .= "</table>";
} 
// end of the rows
$qtyRow .= '</tr>';
$priceRow .= '</tr>';
// echo the table
echo "<table border=\"1\" align=\"center\">";
echo $qtyRow;
echo $priceRow;
echo "</table>";
echo $other_tables;
echo "</p>";  //No idea why this is here
$j=0;
echo"page : ";
for($i=1;$i<=$cc;$i++){

	echo"|";
	$j=$j+$nn; 
}
?>

All right, I think I got it.

Test it out here, the code is below:

<?php 
include "db.php";

//Rows
$qtyRow = '<tr>';
$priceRow = '<tr>';
  
$nn=6; //Number of items, we split this later

$s=mysql_query("SELECT * FROM `test1`");

$c=mysql_num_rows($s);

if($c%$nn==0){
	$cc=$c/$nn;	
}else{
	$cc=$c/$nn+1;	
}

//$cc : Number of pages

$ss=@$_REQUEST['ss']; //Start position (eg: 6)
$other_tables = "";

if($ss=="" || $ss==null){
	$ss = 0; //Set to zero because it is incremented later
}

//Pages
echo "<table border=\"1\" align=\"center\">";
$sql=mysql_query("SELECT * FROM `test1` ORDER BY `id` DESC LIMIT $ss,$nn");
$inc = 0;
while($r=mysql_fetch_array($sql)){
	$id=$r['id'];  
	$name=$r['name'];
	if($inc == 0){
		$qtyRow .= "<tr>";
		$priceRow .= "<tr>";
	}
	$qtyRow .= "<td>$id</td>";
	$priceRow .= "<td>$name</td>";
	++$inc;
	if($inc == 3 || $inc == 6){
		//Display Table
		echo $qtyRow."</tr>";
		echo $priceRow."</tr>";
		echo "</table>";
		
		//To remove extra table
		if(mysql_num_rows($sql) < 6){
			$inc = 7;
		}
		
		//Reset
		if($inc == 3){
			echo "<br><table border='1' align='center'>";
			$qtyRow = "<tr>";
			$priceRow = "<tr>";
		}
	}
}
echo "</table>";
echo "</p>";  //No idea why this is here
$j=0;
echo"page : ";
for($i=1;$i<=$cc;$i++){
	echo"<a href=\"select.php?ss=$j\">$i</a>";
	echo"|";
	$j=$j+$nn; 
}
?>

There. Sorry about that, I missed a check to see if it hit the max value or not.

<?php 
include "db.php";

//Rows
$qtyRow = '<tr>';
$priceRow = '<tr>';
  
$nn=6; //Number of items, we split this later

$s=mysql_query("SELECT * FROM `test1`");

$c=mysql_num_rows($s);

if($c%$nn==0){
	$cc=$c/$nn;	
}else{
	$cc=$c/$nn+1;	
}

//$cc : Number of pages

$ss=@$_REQUEST['ss']; //Start position (eg: 6)
$other_tables = "";

if($ss=="" || $ss==null){
	$ss = 0; //Set to zero because it is incremented later
}

//Pages
echo "<table border=\"1\" align=\"center\">";
$sql=mysql_query("SELECT * FROM `test1` ORDER BY `id` DESC LIMIT $ss,$nn");
$inc = 0;
while($r=mysql_fetch_array($sql)){
	$id=$r['id'];  
	$name=$r['name'];
	if($inc == 0){
		$qtyRow .= "<tr>";
		$priceRow .= "<tr>";
	}
	$qtyRow .= "<td>$id</td>";
	$priceRow .= "<td>$name</td>";
	++$inc;
	if($inc == 3 || $inc == 6 || $inc == mysql_num_rows($sql)){
		//Display Table
		echo $qtyRow."</tr>";
		echo $priceRow."</tr>";
		echo "</table>";
		
		//To remove extra table
		if(mysql_num_rows($sql) <= 3){
			$inc = 7;
		}
		
		//Reset
		if($inc == 3){
			echo "<br><table border='1' align='center'>";
			$qtyRow = "<tr>";
			$priceRow = "<tr>";
		}
	}
}
echo "</table>";
echo "</p>";  //No idea why this is here
$j=0;
echo"page : ";
for($i=1;$i<=$cc;$i++){
	echo"<a href=\"select.php?ss=$j\">$i</a>";
	echo"|";

Are you just copy and pasting random bits of code together? You have bad syntax all over the place, so first things first you need to clean up your code (closing PHP and then the following line re-opening it...)

If you are trying to use multiple pages, Google "php pagination", that'll help you display the correct number of results per page.

Try this...

<?php

$ss = intval($_GET['ss']);  // Intval converts ss into a number and returns 0 if ss is 0 or NOT a number.

$sql=mysql_query("select * from test1 order by id desc limit $ss,3 ");

$sets = 2;
$currentSet = 1;
$count = 0;
$rowCount = 0;
do {
	$idRow = '<tr><th>ID:</th>'; 
	$nameRow = '<tr><th>Name:</th>';
	while($r=mysql_fetch_array($sql) && $rowCount++ < 3)
	{
	 
		$id=$r['id'];  $name=$r['name'];
	 
		$idRow .= "<td>$id</td>";
	 
		$nameRow .= "<td>$name</td>";
	 
		$count++;
	 
	}
	
	$idRow = '</tr>'; 
	$nameRow = '</tr>';
	echo '<table class="ProductTable">'.$idRow.$nameRow.'</table>';
	$rowCount = 0;
	
} while (mysql_num_rows($sql) > $count && ++$currentSet <= $sets)

?>

I cleaned up your code for you, but I can't help you any further if you don't describe with comments what $ss, $nn, and such actually mean.

<?php 
include "db.php";
  
//Rows
$qtyRow = '<tr>';
$priceRow = '<tr>';
  
$nn=3;

$s=mysql_query("select * from test1");

$c=mysql_num_rows($s);

if($c%$nn==0){
	$cc=$c/$nn;	
}else{
	$cc=$c/$nn+1;	
}

$ss=@$_REQUEST['ss'];

if($ss=="" || $ss==null){ 
	$sql=mysql_query("select * from test1 order by id desc limit 3");
	while($r=mysql_fetch_array($sql)){
		$id=$r['id'];  $name=$r['name'];
		$qtyRow .= "<td>$id</td>";
		$priceRow .= "<td>$name</td>";
	}
	// end of the rows
	$qtyRow .= '</tr>';
	$priceRow .= '</tr>';
}else{
	$sql=mysql_query("select * from test1 order by id desc limit $ss,3 ");
	while($r=mysql_fetch_array($sql)){
		$id=$r['id'];  $name=$r['name'];
		$qtyRow .= "<td>$id</td>";
		$priceRow .= "<td>$name</td>";
	}
	// end of the rows
	$qtyRow .= '</tr>';
	$priceRow .= '</tr>';
} 

// echo the table
echo "<table border=\"1\" align=\"center\">";
echo $qtyRow;
echo $priceRow;
echo "</table>";
echo "</p>";  //No idea why this is here
$j=0;
echo"page : ";
for($i=1;$i<=$cc;$i++){
	echo"<a href=\"select.php?ss=$j\">$i</a>";
	echo"|";
	$j=$j+$nn; 
}
?>

i used $nn as what number of things i want to show for example 3 of them in each page and then i used % for both of the conditions if $c%%nn==0 it means the result equally shows 0 pages but in the else situation we have 1 or more objects to show in other pages such as 2 or 3 or... so is it clear ???

excuse me sir but once again i m gonna repeat the question :

this is my result in each page :

10 9 8
k a s

i wanna add another table after this that it remain the information until it is going to next page :

10 9 8
k a s

7 6 5
q z w

the second table continuing info's in each page .

Is there still any things wrong here ?

I don't see where you are seeing that error, when I run the script I see 2 possible pages I can go to. When I first go there I am presented with page 1, which has IDs 9, 8, 7, and 6, 5, 4, then I click page 2 and see the remaining 3 IDs, 3, 2, and 1.

turt2live 5 Junior Poster in Training · Answer 15 · 2011-10-18T05:11:53+00:00

Unless you mean you don't see the first column (being 10)

dr.4030 0 Light Poster · Answer 16 · 2011-10-18T05:13:57+00:00

when I run the script I see 2 possible pages I can go to. When I first go there I am presented with page 1, which has IDs 9, 8, 7, and 6, 5, 4, then I click page 2 and see the remaining 3 IDs, 3, 2, and 1.

so where is 10 ?

if you dont saw the 10 because of the code that i cant see the 1 !

dr.4030 0 Light Poster · Answer 17 · 2011-10-18T05:15:59+00:00

if you add some data like number 11 or 12 or .... you will be see the page still in 2 pages that it is gonna miss numbers from the beginning of them ...

dr.4030 0 Light Poster · Answer 18 · 2011-10-18T05:18:14+00:00

I increased the data to number 13 and now it is ok

but still I don't have number 1 !

probably missed
