[Zope] Form-Through-Script

Mon Aug 13 17:40:35 EDT 2007

I would LOVE to do that. I don't know how :( Can you point me to a good tutorial or explain this a bit and give me some KW to chase down in google?

TIA,

Tony

Sounds like the script should check to see if the user is removing something like:

<input type="checkbox" name="remove" value="item-374623746">

if remove

remove the item

redirect back to the udpated form page

else

send to PP

this way once the item is removed and the same script is called, since there's no remove this time, it'll go to PP.

I'm trying to make a silk purse out of a pig's ear :)

I have a form where purchasers can deselect items they've added to their shopping cart. All the hidden fields have been numbered according to the items they *originally* selected. If they deselect an item, then it will probably necessitate a renumbering of all those hidden fields, since PayPal doesn't tolerate misnumbering: everything must be numbered "1" for all the hidden fields of the first product, "2" for the second, etc. If the customer selects 5 products and deletes the 3rd, then I need to renumber. I wrote a script that can do that. Now, I have to send the form to that script, with all its lovely hidden fields, then reproduce it somewhere so I can send it off to PP. That is, the form must return from the called script to a new page and deliver all the renumbered hidden fields. 

TIA,

Tony

can you describe what you're trying to do a little more clearly?

Well it didn't like that, either:

?

Invalid request
The parameter, doc, was omitted from the request. 

again. But look here:

<td tal:define="docs here/CheckOutAfterEditStuff">

<form action="renumberTheCart(docs)" method="post" enctype="multipart/form-data">
<p metal:use-macro="here/CheckOutAfterEditStuff/macros/main" />

See, I have a definition of "docs", but it's not pointing to a "use-macro" widget. Must be the problem, but how do I do that?
TIA,
Tony

I think you want:

<form action="renumberTheCart(here/CheckOutAfterEditStuff)" method="post" enctype="multipart/form-data">

<td>

<form action=http://example.com/s/renumberTheCart" method="post">

<input type="hidden" name="doc" value="" tal:attributes="value here/CheckOutAfterEditStuff" />?

<p metal:use-macro="here/CheckOutAfterEditStuff/macros/main" />?

</td>

(my tal may be a bit off)

No, it should work the way it is...that is a URL I passed. I changed it to an absolute URL just to double-check, and got basically the same error:

Invalid request
The parameter, doc, was omitted from the request. 

How do I pass the parameter, which in my case is quite long and stashed neatly away in a PT macro?

TIA,
Tony

You might check out the basics about HTML forms first. The 'action' parameter is an URL and *not* some Python-like function call. You specify the destination URL inside the action attribute and pass the parameters as *hidden* form parameters to the URL - either using method GET or POST.?

You'll find more on forms in any HTML tutorial. Start from here:?
