First, name contains the field name of the form element, what you need
to set is the value attribute.

Second, the value should be "CHECKED" not on.

I'm afraid I don't undestand what you're saying. [- $fdat{xxx} = ... -]
used to init form element named xxx last time I looked in the docs.

Yes I tried [- $fdat{xxx} = "checked" -], doesn't work either.

This will work.

<INPUT TYPE="checkbox" NAME="some_field_name" VALUE="true" [$ if defined $fdat{'some_field_name'} $] CHECKED [$ endif $]>

<input name=xxx type=checkbox value=on>

You need the value attribut. Embperl add the checked attribute when the
value in %fdat is the same as that one given in the value attribute of the
tag and will remove it if the values are different.

The example that Erich wrote works too, but is more complex

Thanks everybody who answered. Brief resume: I used to write

<input name=xxx type=text value=[+ $fdat{xxx} +]>

while now I prefer cleaner way using Embperl's feature of automatic form
fields initialization

[- $fdat{xxx} = "stuf" -]
... a lot of HTML ...
<input name=xxx type=text>

This works fine (at least) for text fields and selects, but it fails
badly for checkboxes, where one has to write something like

[- $fdat{xxx} = "some value" -]
... a lot of HTML
<input name=xxx type=checkbox value="some value">

and Embperl adds boolean attribute 'checked' when needed.

I think it would be more intuitive if Embperl allowed for some default
value, so one could write

[- $fdat{xxx} = "some value" -]
<input name=xxx type=checkbox>

and Embperl would understand that "some value" is perlish true/false and
added 'checked' accordingly.
At least it confused me enough so I spent most of this afternoon fooling
around with all options I could think of and even reinstaling Embperl
;-(.

The problem is that you could have multiple checkboxes (or more common
radiobuttons) with the same name:

<input name=xxx type=checkbox value=a>
<input name=xxx type=checkbox value=b>
<input name=xxx type=checkbox value=c>

How should Embperl decide what to do here? I think the current way is
correct, but I add a note to the docs/faq
