Linking from Applet to Module

trevornt

Hi! I need to be able to create a link from a module's applet to the body of the module, and to send a parameter to the body so that it displays information. What I'm currently doing to make the link is this:

$COMPLICATED_HREF = $this->create_callback_href(array('Base_BoxCommon', 'push_module'), array('ModGroup_ModName', 'body'), array('parameter'=>'value'));

And then on the page, I use $_REQUEST['parameter'] to try to catch the value I'm passing. However, while the page itself loads, the parameter appears to be missing (IE, print($_REQUEST['parameter']); prints nothing.)

So my question is this: is there a better/more correct way of doing this? Or am I just doing something wrong?

Thanks!

Hi,

To create an applet you need to include the following code in your main module file:

public function applet($conf, & $opts) {

        // Read applet settings - if you use them

        $status = $conf['status'];

        $title = $conf['title'];

        $rs = here you initialize your recordset;

        $this->rb = $rs->create_rb_module($this);

        $crits = array();

        $columns = array(

            array('field'=>'field_1', 'width'=>6),

            array('field'=>'filed_2', 'width'=>15),

            array('field' => 'status', 'width' => 10));

        // Set options:

        $opts['go'] = true;

        $opts['title'] = $title;

        $conds = array();

        // fields selection

        $conds[] = $columns;

        // Filters = $crits

        $conds[] = $crits;

        // Sorting order

        $conds[] = array();

        // Applet info callback

        $conds[] = array('Path_to_your_Common', 'applet_info_format');

        // Display limit = number of records

        $conds[] = 15;

        // User applet config settings

        $conds[] = $conf;

        // Applet options

        $conds[] = & $opts;

        $this->display_module($this->rb, $conds, 'mini_view');

    }

Please note, that:

 // Set options:

        $opts['go'] = true;

does exactly what you need - it creates a button to take you to the body of your module:

That's pretty cool and a good tip, thanks. However, it's not exactly what I'm looking for.

What I have is a table with a whole bunch of data. In each row, I want to render a link that drills down into the data presented on that row. So, each row has to have a customized link which presents only that row's data in greater detail.

In the module, I have code that can read passed parameters (currently via $_REQUEST, though I can change that if need be) to figure out which row of data was selected to be drilled into by a particular ID number. So, I need some way of passing that one parameter (the ID number) to the module in order to present the data in greater detail.

Thanks!

[/quote:1u3a6ma6]Hi,

However I think that's a proper solution and I would do something like that,
but yes - you're doing something wrong 🙂

to pass regular parameter to the body method use such code



$COMPLICATED_HREF = $this->create_callback_href(

    array('Base_BoxCommon', 'push_module'),

    array('ModGroup_ModName', 'body', array('first_param_value'))

);

I've splitted code into lines to show you what are parameters to the create_callback_href method. Your code was wrong because you were passing $indicator parameter.



	public final function create_callback_href($func,$args=array(),$indicator=null,$mode=null) { ... }

and push_module method



	public static function push_module($module = null, $func = null, $args = null, $constr_args = null, $name = null) { ... }

so args to the push_module are [module, func, args], but those args are also array.
Now your body method signature



public function body($first_param = null) { ... }

It's important to set default param, because menu or button indicated by Jasiek may not pass any parameter.

Ahh, looking at it now, that makes a lot of sense. So my construction of the array was incorrect (no key, just the value, in a non-associative array) and I also put it as a parameter to the wrong function. I see now.

Thanks for your help!
