I assume you get categories from database.

you should try:

<?php

$categories = $rows; //array from database
foreach($rows as $row){
     if($row['name'] == $_POST['category']){
          $isSelected = ' selected="selected"'; // if the option submited in form is as same as this row we add the selected tag
     } else {
          $isSelected = ''; // else we remove any tag
     }
     echo "<option value='".$row['id']."'".$isSelected.">".$row['name']."</option>";
}
?>
