programmatically change link URL in view

Question

I have a view that shows all of a particular user's content (content the user has created on the site). This works fine, but I need to link the results (title field) to the pages where the content is displayed - not to the original node of the created content.

Since the content types may be different, I guess I need to set the URL's programmatically.

For example one content type is "projects" projects are displayed at site.com/projects/!arg

Another content type is "photos" photos are displayed at site.com/photos/!arg.

How do I write a conditional that will set the URL's correctly?

Answer 1

I don't recommend to use views php module,

Menu item with callback:

The idea here is to override all the links of the titles in your view with one link which pass an argument to custom menu callback, then in the callback, you write your PHP code which does the routing.

to implement this solution you need to do the following:

1- Override the link in the view

2- Create callback using hook_menu():

/**
 * Implements hook_menu().
 */
function mymodule_menu() {

  $items['my-routing/%node'] = array(
    'title' => 'Custom callback',
    'page callback' => 'my_custom_callback',
    'page arguments' => array(1),
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );

  return $items;
}

3- Create your custom callback to do the routing:

function my_custom_callback($node) {
  switch ($node->type) {
    case 'product' :
      drupal_goto('project/' . $node->nid);
      break;
    case 'post' :
      drupal_goto('blog/' . $node->nid);
      break;
  }
}

Answer 2

You will need to add several fields to the view and then "exclude from display" so you can use them as tokens: Node type, node id, and node user id.

Then you can change the title field of the node to "output as link" and use the above tokens (views will tell you what they are but assuming they are [node_type] [nid] and [uid]) you would construct the link like: [node_type]/[nid]/[uid]

That works unless you need extra logic to determine the path (if tokens don't match up directly to url arguments). In that case you need the Views Php module, which will allow you to inject php code into the field.

Here is how I got this to work. The code may not be the most elegant due to inexperience, but it does work.

I added node type, node id and author user id fields to the view and set them to exclude from view. Then using a global php field (provided by the "views php" module) I used the following code:

if ($row->type == "single_house_room_photo") {
  print  '<a href="/rooms-houses/' . $row->title . '/' . $row->nid . '/' . $row->uid . '">  ' . $row->title . ' </a>';
} elseif ($row->type == "add_a_product") {
 print  '<a href="/products/' . $row->title . '/' . $row->nid . '">  ' . $row->title . ' </a>';
} else {
 print '<a href="/rooms-houses/' . $row->title . '/' . $row->nid . '/' . $row->uid . '">  ' . $row->title . ' </a>';
}
