Getting form values

Hello,

I am looking for the best way to get the values entered into a form
(without using Formula).

For example, I have a text input field, I want to get the value on
that field and execute some Smalltalk code using that value whenever
the user presses the submit button. Is there a similar way to get the
values like we do using $_POST global variable in PHP or some other
way?

Hi Canol,

In Iliad, we only think in action blocks.

For example, the counter (using GET requests) looks like:

e a
action: [self increase];
text: '++'

But it could be written with a form using POST requests:

e form button
action: [self increase];
text: '++'

As you can see, you don't have to deal with low level details, Iliad
handle them for you.

A typical form in Iliad would look like:

e form build: [:form |
form input
action: [:string | self doSomethingWith: string];
value: 'default value'.
form button
text: 'Ok']

HTH,
Nico

Re: Getting form values

I have some trouble processing more than one form value. Say, I have
two fields like title and body for writing a blog entry, I created two
instance variables called title and body for the ILWidget (which
creates the form to post the entry). I try a code like below in the
contents message of the widget:

e form
build: [:form |
"this is the title field"
form input
action: [:string | "here is a message to self to
assign the value to title instance variable"];
value: 'default value'.

"this is the body field"
form input
action: [:string | "here is a message to self to
assign the value to body instance variable"];
value: 'default value'.

form input
type: 'submit'];

onSubmitDo: ["here is the message to add the entry"].

It appears that the onSubmitDo: block is executed before field values
are assigned. How can I solve this problem?

P.S. Sorry for asking too much -basic- questions :)

Re: Getting form values

I found a input#beSubmitOnChange message which appears to solve my
problem since, I guess, it executes the action blocks every time I
type something. Is this the supposed solution to my problem or is
there another preferred way?

I have some trouble processing more than one form value. Say, I have
two fields like title and body for writing a blog entry, I created two
instance variables called title and body for the ILWidget (which
creates the form to post the entry). I try a code like below in the
contents message of the widget:

e form
build: [:form |
"this is the title field"
form input
action: [:string | "here is a message to self to
assign the value to title instance variable"];
value: 'default value'.

"this is the body field"
form input
action: [:string | "here is a message to self to
assign the value to body instance variable"];
value: 'default value'.

form input
type: 'submit'];

onSubmitDo: ["here is the message to add the entry"].

You can associate actions to the submit buttons too:

e form build: [:form |
    form input action: [:string | ...].
    form textarea action: [:string | ...].
    form ckeckbox action: [:boolean | ...].
    form button "clicking on it will submit the form"
        action: [...] "this action block doesn''t take any parameter"]

Button are submit buttons by default. You don't need to associate an action to send the form, like onSubmitDo: ...
Actions will be executed in the creation order, ie, the input action first, then the textarea action ,then the checkbox action, and finally the button action.

Cheers,
Seb

It appears that the onSubmitDo: block is executed before field values
are assigned. How can I solve this problem?

P.S. Sorry for asking too much -basic- questions :)
