<form id="form" action="<?php echo $_server['php_self']; ?>" method="post">         <fieldset>             <label for="number">ticket count </label>             <input type="number" name="number" />             <input id="submit" type="submit" value="set ages" class="submit"/>              <?php                 $numberoftickets = $_post['number'];                 for($i=1;$i <=$numberoftickets;$i++){                     echo "<select class='ages' name='ages'>";                     echo "<option value='adult'>18 år och uppåt</option>";                     echo "<option value='youth'>13 – 18 år</option>";                     echo "<option value='child'>7 – 12 år</option>";                     echo "<option value='baby'>under 7  år</option>";                     echo "</select>";                 }             ?>          <input class="submit" type="submit" name="submit" value="beställ biljett" />         </fieldset>     </form>     </div><!--content-->     <?php         class ticket         {                      public function price($age)           {             return $price;           }           public function ages($ages)           {                 foreach($ages $f)                 {                     echo "$f</br>";                 }           }          }     ?> 

as <select> inside loop, assume there more 1 select named "ages". if case, this:

echo "<select class='ages' name='ages[]'>"; 

and values in php, use this:

$_post['ages'] 

that array. use for, foreach, implode or whatever need convert arrays text.

please explain more if not meant.
