displaying records across a number of pages

[almystersv]

Hi Guys,

 

I am displaying a large number of records onto one of my webpages. At the moment I am limiting the number i display to the page to 10 and have created a number of pages displaying a group of 10 at a time.

 

Is there anyway of doing it so that a page is automatically created when more records are added or something along those lines?!

 

Thanks

You're creating these pages manually?! Ouch. I suggest you look into pagination. There's a tutorial here on the subject.

You can just do "SELECT * FROM table ORDER BY field DESC LIMIT 10", and fetch that onto a query. The data is looped whenever you refresh the page with a while statement.

 

Also this would be called a pagination.

Hi,

 

I went through that tutorial and it explained a lot of things well but I am having problems with the code.

 

this is what i have...

 

<?php 
session_start();
if (isset($_SESSION['username']) == false){
	header("Location: login.php");
	exit();
}
require "connect.php";

    $limit          = 10;                
    $query_count    = "SELECT count(*) FROM product";     
    $result_count   = mysql_query($query_count);     
    $totalrows      = mysql_num_rows($result_count);  

    if(empty($page)){ 
        $page = 1; 
    } 
         

    $limitvalue = $page * $limit - ($limit);  
    $query  = "SELECT * FROM product LIMIT $limitvalue, $limit";         
    $result = mysql_query($query) or die("Error: " . mysql_error());  

    if(mysql_num_rows($result) == 0){ 
        echo("Nothing to Display!"); 
    } 

    $bgcolor = "#E0E0E0"; // light gray 

?>
<table width ="100%" border="1">
<?php 
     
    while($row = mysql_fetch_array($result)){ 
        if ($bgcolor == "#E0E0E0"){ 
            $bgcolor = "#FFFFFF"; 
        }else{ 
            $bgcolor = "#E0E0E0"; 
        } 

    echo("<tr bgcolor=".$bgcolor.">n<td>"); 
    echo($row["URN"]); 
    echo("</td>n<td>"); 
    echo($row["productName"]); 
    echo("</td>n</tr>"); 
    } 

    echo("</table>"); 

    if($page != 1){  
        $pageprev = $page--; 
         
        ?>
	<a href=\"StationaryOrdersTEST.php&page=$pageprev\">PREV".$limit."</a>
	<?php  
    }else{ 
        echo("PREV".$limit." "); 
    } 

    $numofpages = $totalrows / $limit;  
     
    for($i = 1; $i <= $numofpages; $i++){ 
        if($i == $page){ 
            echo($i." "); 
        }else{ 
         ?><a href=\"StationaryOrdersTEST.php?page=$i\">$i</a>
	 <?php 
        } 
    } 


    if(($totalrows % $limit) != 0){ 
        if($i == $page)
	{ 
            echo($i." "); 
        }
	else{ 
	?>
	 <a href="StationaryOrdersTEST.php?page=$i">$i</a>
	 <?php
        } 
    } 

    if(($totalrows - ($limit * $page)) > 0){ 
        $pagenext = $page++; 
          
        ?>
	<a href="StationaryOrdersTEST.php?page=$pagenext\">NEXT".$limit."</a>
	<?php
    }else{ 
        echo("NEXT".$limit);  
    } 
     
    mysql_free_result($result); 

?> 

 

But it is displaying 20 odd rows of the letter 'n' before outputting the data from the database and also the links are not working for the 'PREV', 'NEXT' or the page numbers.

 

Thanks
