Hi,

 

We have a simple directory app that shows records in alphabetical order.

 

There are two types of record though - a 'premium' record and a 'standard' record.

 

We'd like all the premium records to be showed first then the standard records after.

 

The code we're using at the moment is work ok but is showing the 2 premium records at the top of each page followed by 5 standard records - this is kind of ok for now as there are only 2 premium records, but when their are more the standard records will never display.

 

Any tips to work round this?!

 

directory.php has:

 

showdirectory($category);
showdirectoryfree($category);

 

which calls:

 

	$result = mysql_query("SELECT * FROM accounts WHERE category='$category' AND featured='1' ORDER BY companyname");

print "<table width=\"100%\" bgcolor=\"#000000\">";
print "<td bgcolor=\"#000000\"> <span class=\"greenlinkFont\">> </span><span class=\"boxheadingsFont\">Marketplace - " . $category . "</span></td>";
print "</table><br>";

    while($row = mysql_fetch_array($result))
    {
	echo "<table width=\"100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"2\" bgcolor=\"#FFF78A\" class=\"bodyFont\">";
	echo "<tr>";
	echo "<td width=\"80%\" height=\"25\" bgcolor=\"#9DA373\"><b><span class=\"companyNameFont2\"><a href=\"/" . $row['username'] . "\">" . $row['companyname'] .  "</a></span></b></td>";
	echo "<td width=\"20%\" bgcolor=\"#9DA373\" class=\"bodyFontwhite\" valign=\"middle\"><table><td width=\"80%\" align=\"right\"><img src=\"/images/globe.gif\" width=\"29\" height=\"17\" /></td><td><a href=\"/" . $row['username'] . "\">webpage</a></td></table></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" bgcolor=\"#FFFFFF\">" . $row['address'] . ", " . $row['postcode'] . "</td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" bgcolor=\"#FFFFFF\">Tel: <b>" . $row['telephone'] . "</b></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" bgcolor=\"#FFFFFF\"><a href=\"http://www.multimap.com/map/browse.cgi?client=public&search_result=&db=pc&lang=&keepicon=true&pc=". $row['postcode'] ."&advanced=&client=public&addr2=&quicksearch=" . $row['postcode'] .

if($page > 1){

Get rid of the first half of your page and change the second query to sort by featured instead of making it a WHERE requirement.

 

FYI: Your IF/ELSE to determine the page needs some validation to ensure it is a number. ALWAYS validate user input whether it is coming from GET or POST.

 

<?php

function showdirectoryfree($category)
{
if(!isset($_GET['page'])){
$page = 1;
} else {
  $page = $_GET['page'];
  }

$max_results = 5;
$from = (($page * $max_results) - $max_results); 

$query = "SELECT * FROM accounts
          WHERE category='$category'
          ORDER BY featured, companyname
          LIMIT $from, $max_results";

$result = mysql_query($query) or die (mysql_error());

    while($row = mysql_fetch_array($result))
{
	echo "<table width=\"100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"2\" class=\"bodyFont\">";	
	echo "<tr>";
	echo "<td><b><span class=\"companyNameFont\">" . $row['companyname'] . "</span></b></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td>" . $row['address'] . ", " . $row['postcode'] . "</td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td>Tel: <b>" . $row['telephone'] . "</b></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" bgcolor=\"#FFFFFF\"><a href=\"http://www.multimap.com/map/browse.cgi?client=public&search_result=&db=pc&lang=&keepicon=true&pc=". $row['postcode'] ."&advanced=&client=public&addr2=&quicksearch=" . $row['postcode'] . "&addr3=&addr1=\" target=\"blank\">Map/Directions</a> - <a href=\"/marketplace/sendemail/sendemail.php?emailto=" . $row['username'] . "\" onClick=\"return popup(this, 'notes')\">Send E-Mail</a></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td align=\"left\"><hr width=\"100%\" size=\"1\" noshade=\"noshade\"/></td>";
	echo "</tr>";

	echo "</table>";
}

    
    $total_results = mysql_result(mysql_query("SELECT COUNT(*) as Num FROM accounts WHERE category='$category'"),0);
$total_pages = ceil($total_results / $max_results);

echo "<table width=\"100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\" id=\"pagenumberBox\" class=\"bodyFont\">\n";
echo "<tr>\n";
echo "<td align=\"center\">\n";

if($page > 1){
$prev = ($page - 1);
echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$prev&category=$category\">Previous</a>\n";
}

for($i = 1; $i <= $total_pages; $i++){
if(($page) == $i){
  echo "$i \n";
  } else {
   echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$i&category=$category\">$i</a>\n";
   }
}

if($page < $total_pages){
  $next = ($page + 1);
  echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$next&category=$category\">Next</a>\n";
  }

echo "</td>\n";
echo "</tr>\n";

echo "<tr><td align=\"center\"><a href=\"/marketplace/index.php\">Return to Marketplace</a></td></tr>\n";

echo "</table>\n";

}

?>

Hi mjdamato,

 

Thanks for that - never thought about doing it that way.

 

I'm hitting a stumbling block. I need the featured and non featured to be displayed differently and am using:

 

    while($row = mysql_fetch_array($result))
{

if ($row['featured']='1') {

	echo "<table width=\"100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"2\" bgcolor=\"#FFF78A\" class=\"bodyFont\">";
	echo "<tr>";
	echo "<td width=\"80%\" height=\"25\" bgcolor=\"#9DA373\"><b><span class=\"companyNameFont2\"><a href=\"/" . $row['username'] . "\">" . $row['companyname'] . $row['featured'] . "</a></span></b></td>";
	echo "<td width=\"20%\" bgcolor=\"#9DA373\" class=\"bodyFontwhite\" valign=\"middle\"><table><td width=\"80%\" align=\"right\"><img src=\"/images/globe.gif\" width=\"29\" height=\"17\" /></td><td><a href=\"/" . $row['username'] . "\">webpage</a></td></table></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" bgcolor=\"#FFFFFF\">" . $row['address'] . ", " . $row['postcode'] . "</td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" bgcolor=\"#FFFFFF\">Tel: <b>" . $row['telephone'] . "</b></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" bgcolor=\"#FFFFFF\"><a href=\"http://www.multimap.com/map/browse.cgi?client=public&search_result=&db=pc&lang=&keepicon=true&pc=". $row['postcode'] ."&advanced=&client=public&addr2=&quicksearch=" . $row['postcode'] . "&addr3=&addr1=\" target=\"blank\">Map/Directions</a> - <a href=\"/marketplace/sendemail/sendemail.php?emailto=" . $row['email'] . "&companyname=" . $row['companyname'] . "\" onClick=\"return popup(this, 'notes')\">Send E-Mail</a> - <a href=\"/". $row['username'] . "\">View Webpage</a> </td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" align=\"left\" bgcolor=\"#FFFFFF\"><hr width=\"100%\" size=\"1\" noshade=\"noshade\"/></td>";
	echo "</tr>";
	echo "</table>";

} else {

	echo "<table width=\"100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"2\" class=\"bodyFont\">";
	echo "<tr>";
	echo "<td><b><span class=\"companyNameFont\">" . $row['companyname'] . "</span></b></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td>" . $row['address'] . ", " . $row['postcode'] . "</td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td>Tel: <b>" . $row['telephone'] . "</b></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td colspan=\"2\" bgcolor=\"#FFFFFF\"><a href=\"http://www.multimap.com/map/browse.cgi?client=public&search_result=&db=pc&lang=&keepicon=true&pc=". $row['postcode'] ."&advanced=&client=public&addr2=&quicksearch=" . $row['postcode'] . "&addr3=&addr1=\" target=\"blank\">Map/Directions</a> - <a href=\"/marketplace/sendemail/sendemail.php?emailto=" . $row['username'] . "\" onClick=\"return popup(this, 'notes')\">Send E-Mail</a></td>";
	echo "</tr>";
	echo "<tr>";
	echo "<td align=\"left\"><hr width=\"100%\" size=\"1\" noshade=\"noshade\"/></td>";
	echo "</tr>";
	echo "</table>";
	}


}

 

. . . but it seems to think every record is featured (1) - what might I be doing wrong?

 

Cheers

 

Simon
