Module development and code questions

Hi !
I'm really a newb in module development. I tried and developped a little module with a simple node.
It was working quite nicely in 4.6, but not in 4.7 anymore.
I checked the documentation, but can't find what I've forgotten :(
In fact, the node appears in the block 'create content', but not in the main page when clicking on 'create content' (?q=node/add).
And if I click on my node in the menu, I go back to the general create content page (instead of my form).....
If someone has an idea what I am stupidly forgetting, it would be really great :p !

For those forced to use postgresql, the sql file translated to PostGreSQL

-- start table, dashboard.pgsql
CREATE TABLE dashboard (
nid integer NOT NULL default '0',
name varchar(255),
db_top text,
db_left text,
db_right text,
db_bottom text,
PRIMARY KEY (nid)
);
-- end table

longtext does not exist in pgsql, and integer used as uid in table node is defined as SERIAL.

Hello,

I've installed the event module in my 4.7 b5 version. The problem is when I click on the next month arrows beside the actual month it jumps for example at the moment to May. After this I can click back and reach April. Anybody else had this problem before?

Thanks 4 your help

Greetings

I'm writing a script to read a xml file from the last.fm website. I wrote a module to parse the xml into a block.
This is a part of the code:

Is there a way to check and then drop one of two identical values called from a db using php? For example, when calling up the breadcrumbs when multiple parents is enabled, the top level term is called twice into the breadcrumb, once for each parent term. How could I write an addition to the php to check and then drop the second identical value?

Any suggestions or work arounds welcome.

Mark
