Get selected value from one dropdown list to another? HELP!!!

Hello guys and PHP Developers. I'm new to programming and have a small problem but i cant find solution. So the problem is that i have one page index.php and dropdown list, when i click the button ,,edit,, with method="post" and action="edit.php" im redirected to edit.php. On the edit.php i like to have the same dropdown list with selected value that i before selected on index.php.

Please guys can anyone help me !?

 

send value of dropdown list using POST then grab it $_POST['var'] then echo it out in values

 

Don't forget the SELECTED property.

 

<?php
  echo "<P>".$_POST['dropdown']."</p>";
?>
<form action="change this to something.php" method="POST">
<select name="dropdown">
  <option value="1">First</option>
  <option value="2">Second</option>
  <option value="3">Third</option>
</select>
<input type="Submit" name="Submit">
</form>

Code (markup):

This is what you can use to get the values of select value, but the principles can be applied to other similar forms as well
