Hello, I'm having trouble with an ad module I've created. I have a table of ads in which I have start and end dates and a checkbox selector for the different ad zones. I've set a limit of one image ad to appear in each of the zones, and that works fine, but sometimes NO image appears, which I don't want; I always need at least one ad to show in the zone. What can I add to my code to always have an image appear?
Thanks!
Here's my ad function:
========== start code ============
function ad_content ($zone) {
list($banner_adsRecords, $banner_adsMetaData) = getRecords(array(
'tableName' => 'banner_ads',
'limit' => '1',
'orderBy' => 'RAND()',
'loadUploads' => true,
'allowSearch' => false,
));
list($ad_zonesRecords, $ad_zonesMetaData) = getRecords(array(
'tableName' => 'ad_zones',
));
foreach ($ad_zonesRecords as $zoneRecord) {
if($zoneRecord['num']==$zone) {
foreach ($banner_adsRecords as $record) {
$start_date = strtotime($record['start_date']);
$end_date = strtotime($record['end_date']);
if (time() < $end_date && time() > $start_date) {
if(in_array($zone, $record['zones:values'])) {
foreach ($record['banner'] as $index => $upload) {
echo "<a href='$record[destination_url]'><img src='$upload[urlPath]' width='$upload[width]' height='$upload[height]' target='_blank' /></a>";
}
}
}
}
}
}
}
========== end code ============
