I wont go into the details of my whole project. Simply present this code example and wonder aloud why it only counts to 1. I thought I had a good grasp on php. The initial design of a 3 table database, and a simple script to enter form data went great. I want to pass a paramater back to the initial form page from itself using get to increment the vaule of a variable. The variable is then used to dynamically add a text input form element for adding multiple childrens names per parent name.
This is the simplest example of the problem I am having without posting the whole script. I want to be able to click that link and watch the number add upon succesive clicks. I get undefined variable on line 7 and 10 and it does return the value 1 on first click but nothing on successive clicks. Any help would be awesome.
<?php
//check to see if variable was passed in query string
if (isset($_GET['increment']))
//if so, add 1 to the sum of $increment, unset$_get in prep for next add, //echo the variable for verification
{
$increment++;
unset($_GET);
}
echo $increment;
?>
<html>
<head>
<title>self.php</title>
</head>
<body>
<a href="self.php?increment=true">Count up</a>
</body>
</html>
