RE: RE: [Zope] How does DTML handle return variables from Python
Thank you, thank you, thank you... This works, I can stop banging my head against the wall now :^). -----Original Message----- From: David Burton [mailto:eloquence@eloquent-designs.f2s.com] Sent: Wednesday, June 19, 2002 8:29 AM To: McDonnell, Larry Subject: Re: RE: [Zope] How does DTML handle return variables from Python Nothing in the code that you've sent would directly change part_num. Therefore I'm assuming that part_num is supposed to be set by concat_sub_types_to_part_num(st,sub_type2). In that script are you setting part_num to the concatenated value, or using something like request.set('part_num',st+sub_type2)? If you're just assigning part_num, then that will be a variable local to the script, and will not affect the part_num variable in the calling page. If you've used request.set... and you're still having problems, try replacing the <dtml-var part_num> with <dtml-var "REQUEST.get('part_num')"> HTH, David Burton 19/06/2002 12:51:23, "McDonnell, Larry" <lmcdonnell@protonenergy.com> wrote:
Hi,
In my first dtml doc I have seven select statements to help the user generate a part number. So I stop getting the global undefined error message, I added the input statement for the part_num variable. I set the variable to "zz" so I can see it as a <dtml-var part_num> output on the next dtml doc gen_part_num. The goal is to take the seven select variables to create the part_num variable.
<form method="post" action="gen_part_num">
<body bgcolor="#FFFFFF" text="#000000"> <select name="st1" size="1"> <option value="01-">01</option> <option value="02-">02</option> <option value="03-">03</option> . . <select name="sub_type2" size="1"> <option value="01">01</option> <option value="02">02</option> . . <input name="part_num" type = "hidden" size="2" value="zz">
On the next form it will be a basic re-display of the part number and a submit to add part_num to the db.
<form name="form1" method="post" action="create_part_num"> <p>Your here!!<dtml-var st1><dtml-var sub_type2><dtml-var part_num> pn</p>
<dtml-if expr="part_num=='zz'"> <dtml-call "REQUEST.set('part_num',' ')"> <p><dtml-var part_num>part_num </dtml-if>
<dtml-var expr="concat_sub_types_to_part_num(st1,sub_type2)">
**<dtml-var part_num>pn <input type="submit" name="Submit" value="Submit">
I can see the dtml-vars but when I call the python script part_num is still set to blank. Sorry for the long email. Thanks in advance.

Yes, the Parameter List is set to st1,sub_type2.
Good. Python will return the concatenated parameters, so it must not be getting them. I can't tell where they come from, but you must not be doing something that you think you are doing.
BTW, if you are just concatenating them you won't even need a script:
<dtml-var "REQUEST.st1"><dtml-var "REQUEST.sub_type2">
or
<dtml-var st1><dtml-var sub_type2>
or
<dtml-var "st1 + sub_type2">
or
&dtml-st1;&dtml-sub_type2;
That's all you need (I'm assuming that these variables come from a previously-submitted form, so that they are contained in the REQUEST).
Of course, if you aren't getting these parameters correctly, these simpler forms won't work either.
Maybe you better explain in simple terms just how these two items are getting to your page.
Cheers,
Tom P

I sorted of asked this question before but I am still hitting a wall. I
am
using this python code:
context, container, script, traverse_subpath part_num = st1 + sub_type2 return part_num
But when "part_num" is returned it is blank. I test the script and "part_num" has a return value.
You have to include the two parameters in the script's parameter list, which you will find in the Edit tab for the script. Otherwise they don't get passed to the script.
