The problem is that you are using separate <script>
tags and calling the function before it is defined. These two together do not work well. Also, I'm pretty sure that <script type="text/x-javascript">
does not work anyway since it's outdated and that you want <script type="text/javascript">
You can do the following:
Move function up and fix x-javascript
:
<?php
$username = 'joeblow';
require_once ("/mypath/include/connnect_db.php");
?>
<p>Please only submit this after above form is completely signed.</p>
<form id="item_complete" method="post">
<input name="submit" type="submit" form="item_complete" value="Submit After Signing">
</form>
<script type="text/javascript">
function confirmFunction(){
var r=confirm("Confirm that you have signed the form!");
if (r==true){
window.open("http://smartpathrealty.com/smart-path-member-page/");
}
else {
}
}
</script>
<?php
if(isset($_POST['submit'])) { //if the submit button is clicked
$complete = 'c';
$query = "UPDATE mytbale SET mycolumn='c' WHERE username='$username'";
mysqli_query($con,$query) or die("Cannot Update");
echo "<script> confirmFunction(); </script>";
}
require_once ("/mypath/include/disconnect_db.php");
?>
