如何使用空占位符文本

Question

Well the question is pretty clear. How could i use text from a placeholder e.g from the below text. I've been searching a lot for this and haven't found a solution. Your help would be appreciated.

<input type="text" placeholder="YYYY, MM - 1, DD" name="director_date"
 value="<?php print get_option('director_date');
 ?>" />

For a non javascript solution, you'll have to test for an empty field on form submittal.

<?php
if(empty($_REQUEST['director_date']))
{
    $dir_date = "YYYY, MM - 1, DD"; //Set desired date here.
} else {
    $dir_date = $_REQUEST['director_date'];
}
