Pre-selecting a value in a select box in an etemplate

patta 2012-03-28 22:25:53 UTC #1

Dear all!

I thought it was a quite simple question, but studying
class.custumfields_widget.inc.php (and most of the related files) didn’t
direct me towards the answer:

How can I pre-select a value in a select-field that is created via
etemplate::empty_cell. For example, assume a select box with the
following values:

$sel_options = array(‘key1’ => ‘val1’, ‘key2’ => ‘val2’);

$mycell =
etemplate::empty_cell(‘select’,‘foo’,array(‘sel_options’=>$sel_options));

How can I (pre-)select ‘key2’?

Furthermore, is there any documentation regarding the attributes-array
passed to empty_cell? Or any hint where to look it up? … well …
might be the file where all the single widgets are processed, I guess…

I’m quite new to this list, so it may have been asked before: Is there
any plan to rewrite the etemplate stuff to a more object oriented
approach instead of using an array and a bunch of referenced variables?

Thanks in advance,

Patrick

For normal application development, you use the etemplate editor to
make a template, then in your code you don’t do more than:
$tmpl = new etemplate(‘your_app.template_name’);
$content = array(“foo” => “key2”);
$sel_options[“foo”] = array(…);
$tmpl->exec(‘your_app.file.submit_callback’,$content, $sel_options,…);

See eTemplate intro:
http://community.egroupware.org/index.php?page_name=wiki&lang=&wikipage=CodeCorner3

Furthermore, is there any documentation regarding the attributes-array
passed to empty_cell? Or any hint where to look it up? … well …

The attributes array varies according to the type. They’re documented
in the etemplate reference.
etemplate/doc/reference.html

In progress.
Search for Ralf’s post with instructions to enable our development
work, if you’re really curious. It was some time in the last few
weeks.

Hi there!

For normal application development, you use the etemplate editor to
make a template, then in your code you don’t do more than:
$tmpl = new etemplate(‘your_app.template_name’);
$content = array(“foo” => “key2”);
$sel_options[“foo”] = array(…);
$tmpl->exec(‘your_app.file.submit_callback’,$content, $sel_options,…);

Maybe I’m not doing “normal application development”. I’m working on
custom fields (in calendar) that rely on the resources selected for a
certain event. Users can create resources that have certain additional
fields. Now I’m trying to write the related template, using customfields
as a guideline, and I want to insert a select with a pre-selected value.
I guess your approach won#t help me in that case, does it?

Yes, I know that.

Ah, great, Thank you!

Well now, that’s a little more involved, but the strategy is still the
same. $content has the id => value for everything.

I’m assuming here that you are creating (all 100+) the custom fields
in the calendar, and only want to show the ones that apply for the the
selected resource. That gets different values for each event, rather
than for each resource. If that’s the case, you might want to use the
’field-name’ option of custom fields. Just use a custom field widget
in your template, get it so it displays every single cf.
Then:

In the template, set the widget’s option to “,@resource_cf” (or
",$cont[resource_cf]", I can’t remember…)
In your code, set $content[ ‘resource_cf’] =
‘appropriate,custom,list,for,resource…’

Good morning!

Maybe that helps, thanks!

No, I don’t use custom fields for this. I extended the resources-app to
comprise a new table with the user-definitions for the RSFs (resource
specific fields) and a corresponding tab in the edit template. That is
very similar to the cf implementation (except for the storage in the
table) of the definition of app-wide cfs and thus worked quite fine. But
the interface for the calendar, where the user has to fill the rsfs with
values is a bit more complex.

Then:

In the template, set the widget’s option to “,@resource_cf” (or
",$cont[resource_cf]", I can’t remember…)

In your code, set $content[ ‘resource_cf’] =
‘appropriate,custom,list,for,resource…’

I’ll keep this in mind, thank you!
