[SOLVED] concatenate <select> values ONLY if they've been selected??

[pikemsu28]

i have a form that has four select dropdowns that i want to implode it into an array but ONLY if the dropdown has a value other than SELECT.  I can get it to work as long as i populate all the menus but if i dont populate one 'SELECT' is posted to my array and i dont want that.  Can someone please help?!  point me in the right direction!!!!

 

<form id="search" name="search" method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<select class="small" name="dropdown[]">
  <option selected="selected">Select</option>
  <option value="option">option</option>
  <option value="option1">option1</option>
  <option value="option2">option2</option>
</select><br />
<select class="small" name="dropdown[]">
  <option selected="selected">Select</option>
  <option value="option">option</option>
  <option value="option1">option1</option>
  <option value="option2">option2</option>
</select><br />
<select class="small" name="dropdown[]">
  <option selected="selected">Select</option>
  <option value="option">option</option>
  <option value="option1">option1</option>
  <option value="option2">option2</option>
</select><br />
<select class="small" name="dropdown[]">
  <option selected="selected">Select</option>
  <option value="option">option</option>
  <option value="option1">option1</option>
  <option value="option2">option2</option>
</select><br />
<input id="search" name="search" type="submit" value="Search" />
</form>
<?php
if(isset($_POST['search']))
{

if(isset($_POST['dropdown'])){$dropdown = implode(', ', (isset($_POST['dropdown']) ? ($_POST['dropdown']) : 'Select'));}
echo $dropdown;
}
?>
