I'm creating a simple registration page:

Solution 1:

At the top:

$birthdayMonth = $_POST['birthdayMonth']

In the select:

<selectname="birthdayMonth"><optionvalue="-1">Month:</option><optionvalue="01"<?phpecho$birthdayMonth == '01' ? 'selected="selected"' : ''; ?>>Jan</option><optionvalue="02"<?phpecho$birthdayMonth == '02' ? 'selected="selected"' : ''; ?>>Feb</option><optionvalue="03"<?phpecho$birthdayMonth == '03' ? 'selected="selected"' : ''; ?>>Mar</option><optionvalue="04"<?phpecho$birthdayMonth == '04' ? 'selected="selected"' : ''; ?>>Apr</option><optionvalue="05"<?phpecho$birthdayMonth == '05' ? 'selected="selected"' : ''; ?>>May</option><optionvalue="06"<?phpecho$birthdayMonth == '06' ? 'selected="selected"' : ''; ?>>Jun</option><optionvalue="07"<?phpecho$birthdayMonth == '07' ?

This is a really dirty of what doing what you want, but it will work:

It would be better to use loop to build the dropdown and then add the selected="selected" value to the correct option.

Solution 3:

<optionvalue="03"<?phpecho$_POST['birthdayMonth'] == '03' ?
'selected="selected"' : ''?>>Mar</option>
