使用会话将数据发布到输入中使用if

Question

I'm trying to create my first if else statement using a 2 page form. At the end of page 1 it uses sessions to save all the post data and automatically insert it into page2 form.

I'm trying to get it were if someone leaves the field blank it will insert Add a Driver into the input.

If the user places info in page 1 however I want it to echo whatever the user typed in page1.

I can successfully get it to echo from page 1 by just using the echo command and I can get it to echo add a driver if the field is left blank. However if a user types into the field its still echoing add a driver and not what he typed via the echo ($_POST['test1']); field. what am i doing wrong? here is the page the php is in the 2nd input field http://test.solidinsurance.com/page1.php

<?php        
if (isset($_POST["test1"])) {
echo "Add a Driver";
} else {
echo ($_POST['test1']);
}
?>

Answer 1

changed isset to empty if (empty($_POST["test1"])) { echo "Add a Driver"; } else { echo ($_POST['test1']); } ?> so if the post is empty it echos add a driver. if the post is not empty it echos whatever the user types in page 1 test1 post.
