db var chage

I have a script pulling data from mysql db. I have a date field that automatically inserts 0000-00-00 by default. So my code goes

if ($row['trained'] == "0000-00-00") {
$row['trained'] ="<img src='/track/images/icon_x.gif'>";
} else {
$row['trained'] ="<img src='/track/images/icon_check.gif'>";
}

If the date in the db is 0000-00-00 then it will display icon_x.gif if it has any other date it will display icon_check.gif.

I want to know how i can make it show the image like it is and display the alt text with the date on the icon_check.gif

Thanks,
Brian

else {
$row['trained'] ='<img src="/track/images/icon_check.gif" alt="' . $row['trained'] .'">';


Is this what you want?
