[SOLVED] Pagination problem

[JPark]

Let's say that I have a script which queries the db and returns 10 items at a time and then sets up a link to see the next page, etc.

 

Here's the problem... if I have 43 items in the db, I will get 4 pages (items 0-9, 10-19, 20-29 and 30-39),  I lose the last 4 items because there in less than 10 left.

 

How do I fix that??

 

 

//number of records to be displayed per page
$records_per_page = 5;

//look for starting marker
//if not available, assume 0
if (!$_GET['start'])
  $start=0;
else
  $start = $_GET['start'];



//open connection to MySQL server
$connection= mysql_connect('host', 'password', 'user') 
or die ('Unable to Connect');

//select database
mysql_select_db('db') or die ('Unable to select database');

// create and execute query to count available records
$query= "SELECT COUNT(shirtType) FROM shirts WHERE sex='MEN' && shirtType='Ringer T-Shirt'";
$result= mysql_query($query) or die ('Error in query: $query.'.mysql_error());


//get the total number of rows
$row= mysql_fetch_row($result);
$total_records= $row[0];

$total_pages = ceil($total_entries / $entries_per_page);
$offset = ($page_number - 1) * $entries_per_page;

//if records exist
if (($total_records > 0) && ($start < $total_records)) {
// Retrieve all the men's shirt data from the "shirts" table
$result = mysql_query("SELECT * FROM shirts WHERE sex='MEN' 
&& shirtType='Ringer T-Shirt' LIMIT $start,$records_per_page")
or die(mysql_error());  

	// store the record of the "shirts" table into $row
	$row = mysql_fetch_array($result) or die(mysql_error());

	// Print out the contents of the entry 

	while($row = mysql_fetch_array( $result )) {
		// Print out the contents of each row into a table
		echo "<a href ='". $row['url']."'><img src='". $row['imageUrl']. "' border='0'></a>";
		echo "<br>";
	} 

// set up the previous page link
// this should appear on all pages except the first page
// the start point for the preious page will be
// the start point for this page
// less the number of records per page

//yes -- first page
if ($start == 0) {
echo "Previous Page     <a href=" . $_SERVER['PHP_SELF'] . "?start=" . ($start+$records_per_page) .
">Next Page</a>";
}
//

// set up the "next page" link
// this should appear on all pages except the last page
// the start point for the next page
// will be the end point for this page

//yes -- middle pages
if ((($start+$records_per_page) < $total_records) && ($start > 0)) {
echo "<a href=" . $_SERVER['PHP_SELF'] . "?start=" . ($start-$records_per_page) . ">Previous
Page</a>     <a href=" . $_SERVER['PHP_SELF'] . "?start=" . ($start+$records_per_page) .
">Next Page</a>";
}
//

// yes -- last page	
if ((($start+$records_per_page) >= $total_records) && ($start > 0)){
echo "<a href=" . $_SERVER['PHP_SELF'] . "?start=" . ($start-$records_per_page) . ">Previous
Page</a>     Next Page";
}

//$srpg= ($start+$records_per_page);
//echo "<br>Start + Records per page= ".$srpg;
//echo "<br />Total records= ".$total_records;
// at ?start=15, $srpg = 20 and $total_records =21.  I am missing the 
//last shirt (because there are less than 5 left?)

}

 

Thanks,

Both these are easy to implement. One easier than the other:

There's a pagination tutorial here that you should look at. Pay attention to the main logic of it.

Thanks waynewex and jpratt! 

 

While both links are quite informative, I like the Crayon Violet tutorial better.  Just my personal opinion...

 

Thank you both for your help.  It works like a charm.
