You can do it in a number of ways, the simplest (and probably least elegant) is to do something like this:
<select class="styled" name="state_trainer">
<?php
$myCity='london'; // assumed to be data from database...
echo '<option'.($myCity=='-select-') ? ' selected ' : ' ' .'-select-</option>';
echo '<option'.($myCity=='washington') ? ' selected ' : ' ' .'washington</option>';
?>
This is of course horrid.
I would rather suggest that you check the data as you are pulling your information out of the database and putting your initial dropdown list together.
If you are making an array of data to create the drop down list (for example) check it right there and then. If the city matches what you want, do it inside your loop right off the bat.
$usersCity="london";
$myCityList=array();
while( ... ) // Database loop that is pulling the data from the database.
{
$selected='';
if($userCity==$row['city'])
{
$selected=' selected ';
}
$myCityList[]='<option'.$selected.'>'.$row['city'].'</option>';
}
Then to display the drop down list, you can simply do this:
$cityCount=count($myCityList);
for($i=0;$i<$cityCount;$i++)
{
echo $myCityList[$i].'\n';
}
The users city will already be selected.
