如何从block_view调用模块中的函数

Question

I am writing a Drupal 7 module that queries my db and prints out a view_block with a list of projects belonging to the current logged user:

ID ClientName ProjectName ProjectDescription
 1     mickey       toon1        bla bla bla
 2      mouse       toon2        bla bla bla

At this point, I need the user to select one of his projects to proceed to visualization.

EDIT:

what I need to do is to call another function in my module and pass it the ID for the project selected by the current user.

I know how to add a link to every row in the table and bring the ID value with me to the next page, using GET['id'] to retrieve it, but I really don't want to change the url for security reasons - namely, I don't want users to change the ID in the url and see other people's projects, nor prevent it to happen. I prefer to keep url clean as much as possible.

What is in Drupal 7 the right logic to allow the user select one project and then call another function in my module to load data according to the selected ID?

Answer 1

I would implement an hook_menu. With this solution you need to pass the Id of the project in the url, but an hook menu allow you to define 2 functions. The access function will check if the user has access to the project, the callback function will retrieve the project and show the project details.

This is a simple example of how I would implement it:

/**
 * Implements hook_menu().
 */
function my_module_menu() {
    $items['my_module/show_project_detail/%'] = array(
        'title' => 'Show Task Detail',
        'access callback' => 'show_project_access',
        'access arguments' => array(1),
        'title callback' => false,
        'page callback' => 'show_project',
        'page arguments' => array(1),
    );
    return $items;
}

function show_project_access( $sProjectId ){
    // checks if the user has access to $sProjectId.
    // returns true if he has access, otherwise returns false
}

function show_project( $sProjectId ){
    //returns the html of the task's detail view
}

Then to call the hook_menu you will call this url https://my_drupal/my_module/show_project_detail/123 where 123 is the project Id.
