Top drupal-7 frequently asked interview questions
Goal: To send a email with a list of URLs of nodes.
In my custom module I have managed to get the node id which the user wants and I now want to get the URL of each node to put into my email.
I searched the db and used google but I can't seem to find the right solution.
It seems we need to construct the URL something like this:
<?php
global $base_url;
$link=$base_url."// few more parameters

How can I modify or pre-process the <body> tag to add the class body? I don't want to create a whole html.tpl.php just to add a class.

Filter by user:current is missing however, where can it be found/enabled?
I must be missing something simple.

I would like to show a node inside another node. So I retrieve the node id of the second node and I would like to render/print/... it inside another node.
But I'm not sure how to do this. I've tried drupal_render, node_view, print,... but with no results. Any advice?
$nid = $node->field_linked_fiche['und'][0]['nid'];
$fullFiche = node_load($nid);
EDIT - the whole template

We were working with Drupal 7 and trying to rewrite the views output
We need the src of the image field , not the whole image tag.
Clicking on
Rewrite the output of this field
[field_first_image] : Gives the whole content ie with tag ,
We tried to display the below ones
[field_first_image-fid] == Raw fid
[field_first_image-alt] == Raw alt
[field_first_image-title] == Raw title
But the same ( [field_first_image-fid] ) thing is displayed in the view. Is there a way we can get the src from the views rewrite ?

In Drupal 6, it was easy to insert a block into a template with the following code:
$block = module_invoke('views', 'block', 'view', 'block_name');
print $block['content'];
However, using the same instructions in Drupal 7 does not seem to work. I have looked around and cannot find the new method.
Does Drupal 7 have a routine that can allow for pro grammatically inserting a block into a template or node?

Could someone provide a architectural overview of the Drupal 7 control flow? Perhaps in the sense of a flowchart about how a page gets generated. What additional resources would you suggest consulting with regards to how Drupal works?

OK, I finally figured out how to add (or edit) form controls through the form API in Drupal.
But now, I would like to add text to a form. Not a <textarea>, and not a <textfield>; both of which can be edited by the user. I would like to add <p>static text</p>, written by me, to be read by the user.
How would one do that?

After having just registered a new account and created a profile how would I log a user in?
I have tried :
global $user;
$user = user_load($account->uid);
or
global $user;
$user = user_load(array('mail' => $_POST['email'], 'pass' => trim($_POST['password'])));
but neither work and the second results in an error about array_flip.

Is there a way to export a content type from a site and import it to another? I haven't found any modules to do that yet.
How would you achieve that? It's a useful thing to be done otherwise it is very time consuming to create the same content type over and over again.
