How to display one banner ad every third row in php? - php

Question

Sorry for my English,
I need to display a banner ad from a database every third row in php. Banner ads and rows with the classified are selecting from database. To this moment I create something like this:
Rows with the classifieds from database:
while(#$row_select_kat = mysql_fetch_assoc($results_select_kat))
{
... //classifieds from database
if(($row_select_kat['id_ogloszenia']%3)==0)
{
$lim = 1;
echo"<div id=\"rek_poz_a\">";
modAddsDisplayHelper::wyswietlReklamyPozA();
echo"</div>";
}
}
Selecting banner ads from databes:
public static function wyswietlReklamyPozA()
{
$baza_danych = &JFactory::getDbo();
$query_sel_all_banners = "SELECT * FROM juxhv_banners";
$baza_danych->setQuery($query_sel_all_banners);
$baza_danych->query();
$banner_ads = $baza_danych->loadObjectList();
echo$query_sel_all_banners;
echo"Liczba x= ".$l_ogloszen;
foreach($banner_ads as $banner_ad)
{
if($banner_ad->state==1)
{
echo"$banner_ad->name<br/><img src=\"images/$banner_ad->username/bannerwerbung/$banner_ad->zdjecie\" width=\"434px\" height=\"94px\" />";
}
else
{
echo"No banner";
}
}
}
When I doing this in that way at every three rows displaying all three banner ads. How can I display only one banner ad every three rows?

Answer 1

You need to use external counter variable which will be incremented on each iteration and depending on its condition you can check modulo condition: Please see the following updated code.
[code]
$recordCount = 0;
while(#$row_select_kat = mysql_fetch_assoc($results_select_kat))
{
if(($recordCount%3)==0)
{
echo"<div id=\"rek_poz_a\">";
modAddsDisplayHelper::wyswietlReklamyPozA();
echo"</div>";
}
$recordCount++;
}

if($banner_ad->state == 1) {
echo"$banner_ad->name<br/><img src=\"images/$banner_ad->username/bannerwerbung/$banner_ad->zdjecie\" width=\"434px\" height=\"94px\" />";
break;
}
In this way you only print one banner, but always will be the first with state == 1 in the database.
Maybe is better improve the query:
$query_sel_all_banners = "SELECT * FROM juxhv_banners WHERE state = 1 LIMIT 1";
That will give you the same result, I think.
I hope it helps
