Sorting data in a table and creating multiple pages possible?

[eluzion]

Right now I have a HTML table that is populated with data from my MySQL database. I have it setup where if you click one of the row titles, it sorts in ascending and descending order (if you click it again).

 

Now I'm trying to figure out how to go about limiting the amount of results that the table is populated with, such having only 10 entries from the MySQL database shown at a time.

 

Here is the code I have so far for just the ascending and descending deal:

 

if(isset($_GET['sortby'])) { 
	$sortby = $_GET['sortby']; 
		if(strcasecmp($sortby, "desc")==0) { 
			$newsort = "asc"; 
		} 
			else { 
			$newsort = "desc"; 
			} 
} 
	else { 
		$sortby = "asc"; 
		$newsort = "desc"; 	
		} 

if(isset($_GET['orderby'])) { 
	$orderby = $_GET['orderby']; 
	$query_sort = "SELECT * FROM servicelog ORDER BY ".mysql_real_escape_string($orderby);

		if(strcasecmp($sortby, "desc")==0) {  
		$query_sort.= " DESC"; 
		} 
			else { 
			$query_sort.= " ASC limit 0,10";
			} 

		// page numbering
		if(isset($_GET['page'])) {
			$query_sort.= " LIMIT 0, 10";
		}

} 
	else {
		$query_sort = 'SELECT * FROM servicelog ORDER BY date_checkedin DESC limit 0,10';
		}
$result = mysql_query($query_sort);

?>
<b>SERVICE LOG</b>
<br /><br />
<table width="100%" border="0" cellspacing="1" cellpadding="0">
  <tr bgcolor="#CCCCCC">
    <td width="80"><a href="<? echo $_SERVER['PHP_SELF']."?orderby=date_checkedin&sortby=$newsort";?>">Date</a></td>
    <td width="60"><a href="<? echo $_SERVER['PHP_SELF']."?orderby=invoice_number&sortby=$newsort";?>">Invoice</a></td>
    <td width="120"><a href="<? echo $_SERVER['php_SELF']."?orderby=name_first&sortby=$newsort";?>">First Name</a></td>
    <td width="120"><a href="<? echo $_SERVER['php_SELF']."?orderby=name_last&sortby=$newsort";?>">Last Name</a></td>
    <td width="100"><a href="<? echo $_SERVER['php_SELF']."?orderby=phone&sortby=$newsort";?>">Phone</a></td>
    <td width="140"><a href="<? echo $_SERVER['php_SELF']."?orderby=computer&sortby=$newsort";?>">Computer</a></td>
    <td width="80"><a href="<? echo $_SERVER['php_SELF']."?orderby=computer_type&sortby=$newsort";?>">Type</a></td>
    <td width="130"><a href="<? echo $_SERVER['php_SELF']."?orderby=store&sortby=$newsort";?>">Store</a></td>
    <td width="90"><a href="<? echo $_SERVER['php_SELF']."?orderby=computer_status&sortby=$newsort";?>">Status</a></td>
    <td> </td>
  </tr>

<?php
while ($row = mysql_fetch_assoc($result))
{
?>
  
  <tr <?php if($row['computer_status'] == "Complete") { echo 'bgcolor="#a6ff9d"'; }
   			if($row['computer_status'] == "Awaiting Info") { echo 'bgcolor="#fffc9d"'; }
		if($row['computer_status'] == "In Repair") { echo 'bgcolor="#ff9d9d"'; }
		if($row['computer_status'] == "Picked Up") { echo 'bgcolor="#ade7ff"'; }
    ?>>
    <td><?= $row['date_checkedin'] ?></td>
    <td><a href="<?= $_SERVER['PHP_SELF'].'?edit_id='.$row['id'] ?>"><?= $row['invoice_number'] ?></a></td>
    <td><?= $row['name_first'] ?></td>
    <td><?= $row['name_last'] ?></td>
    <td><?= $row['phone'] ?></td>
    <td><?= $row['computer'] ?></td>
    <td><?= $row['computer_type'] ?></td>
    <td><?= $row['store'] ?></td>
    <td><?= $row['computer_status'] ?></td>
    <td> </td>
  </tr>

 

Any ideas how I can limit it to only display a specified number of data (maybe by having options for 15, 30, 50, 100) and also have a list of page numbers at the bottom? All of this while still keeping the functionality of being able to sort in ascending and descending order.

Hello:

 

Try this website for some info: http://www.designplace.org/scripts.php?page=1&c_id=25

 

Here's the code:

 

test.php

<form name="form" action="search.php" method="get">
  <input type="text" name="q" />
  <input type="submit" name="Submit" value="Search" />
</form>

 

 

search.php

<?php

  // Get the search variable from URL

  $var = @$_GET['q'] ;
  $trimmed = trim($var); //trim whitespace from the stored variable

// rows to return
$limit=10; 

// check for an empty string and display a message.
if ($trimmed == "")
  {
  echo "<p>Please enter a search...</p>";
  exit;
  }

// check for a search parameter
if (!isset($var))
  {
  echo "<p>We dont seem to have a search parameter!</p>";
  exit;
  }

//connect to your database ** EDIT REQUIRED HERE **
mysql_connect("localhost","username","password"); //(host, username, password)

//specify database ** EDIT REQUIRED HERE **
mysql_select_db("database") or die("Unable to select database"); //select which database we're using

// Build SQL Query  
$query = "select * from the_table where 1st_field like \"%$trimmed%\"  
  order by 1st_field"; // EDIT HERE and specify your table and field names for the SQL query

$numresults=mysql_query($query);
$numrows=mysql_num_rows($numresults);

// If we have no results, offer a google search as an alternative

if ($numrows == 0)
  {
  echo "<h4>Results</h4>";
  echo "<p>Sorry, your search: "" . $trimmed . "" returned zero results</p>";

// google
echo "<p><a href=\"http://www.google.com/search?q=" 
  . $trimmed . "\" target=\"_blank\" title=\"Look up 
  " . $trimmed . " on Google\">Click here</a> to try the 
  search on google</p>";
  }

// next determine if s has been passed to script, if not use 0
  if (empty($s)) {
  $s=0;
  }

// get results
  $query .= " limit $s,$limit";
  $result = mysql_query($query) or die("Couldn't execute query");

// display what the person searched for
echo "<p>You searched for: "" . $var . ""</p>";

// begin to show results set
echo "Results";
$count = 1 + $s ;

// now you can display the results returned
  while ($row= mysql_fetch_array($result)) {
  $title = $row["1st_field"];

  echo "$count.) $title" ;
  $count++ ;
  }

$currPage = (($s/$limit) + 1);

//break before paging
  echo "<br />";

  // next we need to do the links to other results
  if ($s>=1) { // bypass PREV link if s is 0
  $prevs=($s-$limit);
  print " <a href=\"$PHP_SELF?s=$prevs&q=$var\"><< 
  Prev 10</a>&nbsp ";
  }

// calculate number of pages needing links
  $pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division

  if ($numrows%$limit) {
  // has remainder so add one page
  $pages++;
  }

// check to see if last page
  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

  // not last page so give NEXT link
  $news=$s+$limit;

  echo " <a href=\"$PHP_SELF?s=$news&q=$var\">Next 10 >></a>";
  }

$a = $s + ($limit) ;
  if ($a > $numrows) { $a = $numrows ; }
  $b = $s + 1 ;
  echo "<p>Showing results $b to $a of $numrows</p>";
  
?>

 

Hope it helps.

Here's a few other sites I've looked at:

 

1) http://www.joedolson.com/search-engine/?q=california&o=vintner&d=DESC

i have same thing but all i did was used this code:

 

$query = $db->execute("select `Value name`, from `table name` order by `ID` desc limit 50");
