You need to wrap your code in a select statement!
An option statement wont work without the select tag around it:
<html> <body> <select> <!-- Start the select statement --> <!-- Your Code --> <?php $num = 4; for ($i=1; $i < 10; $i++) { ?> <option value="<?php echo $i; ?>" <?php if($num === $i){ echo "selected"; }; ?>><?php echo $i; ?></option> <?php } ?> <!-- End your code --> </select> <!-- End the select statement --> </body> </html>讨论(0) -
After your edit, it looks like this is your main problem:
$date = 2015-02-30;This is not what you think it is. It should be quoted like this:
$date = '2015-02-30';Otherwise,
$dateis a not a string, it's a math expression that evaluates to(int) 1983, sosubstr($date, 8, 2);will evaluate tofalse, not30, and then obviously your option won't be selected.讨论(0)
