Question

I want to show a template content if ad not available

i use this code but

both ad & template content are showing

<?php
    if(dt_show_ads('position=Header&before=<div>&after=</div>'))
    {
?>
    <!-- Some content here -->
<?php
    }
    else
    {
        include TEMPLATEPATH.'/templates/newsleft_col.tpl.php';
    }
?>

Answer 1

dt_show_ads('position=Header&before=<div>&after=</div>') seems to not return any value. This evaluates to false in PHP.

What dt_show_ads() does, though, is to insert ad html (if there is any).

Therefor, no matter if there are ads or not, your else part is always executed.

A quick google query didn’t turn up any sensible documentation on dt_show_ads for me, you might wanna try this though:

if (strlen($ads = dt_show_ads('position=Header&before=<div>&after=</div>&echo=false')) !== 0)
{
    echo $ads;
    // whatever other content you want to show
}
else
{
    include TEMPLATEPATH.'/templates/newsleft_col.tpl.php';
}

Edit:

Since, per your comment, dt_show_ads() doesn’t support the WP-semi-standard echo argument, you’ll need to buffer its output to be able to check it:

ob_start();
dt_show_ads('position=Header&before=<div>&after=</div>');
$ads = ob_get_contents();
ob_end_clean();

if (strlen($ads) !== 0)
{
    echo $ads;
    // whatever other content you want to show
}
else
{
    include TEMPLATEPATH.'/templates/newsleft_col.tpl.php';
}
