Set the value of a field ?

[duddy67]

Hi,

I'm desperatly trying to set the value of a backend component field but I can't make it.
I tried with the setValue function from the JForm class:

Code: Select all

$this->form->setValue('title', 'some value'); 

in the view.html.php file and in the default.php file but it doesn'nt work.
I checked my form file and all seems ok, so I don't understand what's wrong.

Is any specific way to use the setValue function ?


Thanks for your help.

Ok I've got it.

First the API documentation (http://docs.joomla.org/API16:JForm/setValue) is slightly wrong.
It says that the prototype of the function is :

Code: Select all

public function setValue($field, $value, $group = '_default')

BUT in the joomla/form/form.php file the prototype is:

Code: Select all

public function setValue($name, $group = null, $value = null)

The arguments order is different.
Next, I therefore modified my code as follow:

Code: Select all

$this->form->setValue('title', 'details', 'some value'); 

'details' is the name of the fieldset wich contains the title field, but setValue doesn't work either.
So, either I don't understand what $group means or there's a bug somewhere in the setValue function.

Finally I modified my code again :

Code: Select all

$this->form->setValue('title', null, 'some value'); 

and that's works ! (at last).

I don't know if the setValue gonna be modified in the next Joomla's updates but
it worth to keep an eye on it.

Hello,

so maybe you can help me with my issue?

I think the problem is similar?

I think the problem is similar?

Nope it doesn't.
First did you learned about the JForm class and the way to create a form
in a component ?
The form creation is totally different between Joomla1.5 and Joomla1.6

Once you'll be comfortable with that, you could get your calendar with some code looking like that:

Code: Select all

<field name="created" type="calendar"
		label="JGLOBAL_FIELD_CREATED_LABEL" description="JGLOBAL_FIELD_CREATED_DESC"
		class="inputbox" size="22" format="%Y-%m-%d %H:%M:%S"
		filter="user_utc" />

Hope it helps

Ok I've got it.

Hey duddy67... THANKS!

I spent hours trying to get the setvalue to work and your post saved me. Unfortunately, I still can't get the bind() function to work. I don't suppose that you have hand any related difficulty there?

Thanks!

I struggled with trying to get the setValue to work for the form fields but it works great just using:

$this->form->bind($associated_array)

I execute that before the $this->form->getFieldset() and it pre-filled the values.
