Getting two session varibles into one hidden form field

Question

In a hypothetical exaple, if my first session variable is kt_user_name and it's value is bestperson, and my second variable session is kt_exerreference and it's value is ex1a, I'd like have the value submitted in the hidden form field to be bestpersonex1a (without any spaces if possible). This is the code that I have for the hidden form field that submits the server variables:
<br />
<br />
<form>
<input type="hidden" name="exerreference" id="exerreference" value="<?php echo $_SESSION['kt_user_name'].$_SESSION['kt_login_user']; ?>" />
<br />
<br />But the form also has a php section above the head that seems to add the values to the databse. Here is the beginning of the code with the the first 4 values:
<br />
<br />// Add columns
<br />$ins_exer1-&gt;setTable("exer1");
<br />$ins_exer1-&gt;addColumn("user_name", "STRING_TYPE", "SESSION", "kt_user_name"."kt_login_user");
<br />$ins_exer1-&gt;addColumn("exerreference", "STRING_TYPE", "SESSION", "kt_user_name");
<br />$ins_exer1-&gt;addColumn("Shapes_present_with_target", "STRING_TYPE", "POST", "Shapes_present_with_target");
<br />
<br />My question is how do I also configure the code in the 2nd string of this "Add Columns" code to insert both server variables? When I put one server variable as the value in this code (0n line 2), it only inserted the one session varialbe value (not 2 as are in the form field). As you can see, I currently have "kt_user_name"."kt_login_user" which is givig me server errors.
<br />
<br />Here's another idea that didn't work yet:
<br />
<br />// Add columns
<br />$user = $_SESSION['kt_user_name'].$_SESSION['kt_login_user'];
<br />$ins_exer1-&gt;setTable("exer1");
<br />$ins_exer1-&gt;addColumn("user_name", "STRING_TYPE", "SESSION", "$user");
<br />$ins_exer1-&gt;addColumn("exerreference", "STRING_TYPE", "SESSION", "kt_user_name");
<br />$ins_exer1-&gt;addColumn("Shapes_present_with_target", "STRING_TYPE", "POST", "Shapes_present_with_target");
<br />
<br />Any ideas on the correct syntax?
<br />
<br />Thanks for any help.</form>

Answer 1

Günter,
<br />
<br />I think I did as you suggested. I put this as the form field:
<br />
<br />
<form>
<input type="hidden" name="exerreference" id="exerreference" value="<?php echo $_SESSION['kt_user_name']; ?><?php echo $_SESSION['kt_login_user']; ?> <br />" />
<br />
<br />and changed back the Add columns section to this:
<br />
<br />// Add columns
<br />$ins_exer1-&gt;setTable("exer1");
<br />$ins_exer1-&gt;addColumn("user_name", "STRING_TYPE", "SESSION", "kt_user_name");
<br />$ins_exer1-&gt;addColumn("exerreference", "STRING_TYPE", "SESSION", "kt_user_name");
<br />
<br />The form does submit now, but only the kt_user_name server varible is showing up in the exerreference field of the databaswe, not also the kt_login_user server variable.
<br />
<br />Any ideas on what to do to get it working right? Do I need to modify the exerreference string in the Add columns section?
<br />
