Module development and code questions

Does anybody know if there is a module for foreix exchanges management?
Need to be able to 'change' money between different currencies on-the-fly.
Something like www.xrates.com
I've seen the contributed currency module but it looks as if it can only convert
from only two configured costant currencies. How could I have a multi-currency converter?

Cheers

Hi

I've scoured the site looking for a module which will help me manage a simple webcatalog providing listings and links for suppliers of information for the services I'm interested in (business planing) and haven't found anything.

I would like my users to add their own links in a catalog so that the resources offered on my site can grow organically. Link exchange would also be nice between users.

Is there anything there already that I've overlooked? Are there plans to develop something in this line?

As a non-programmer, I'm glad of any help I can get!

How can I get the album description to appear within the album itself? I don't want it appearing on the list of albums, at the top of the album, with the contents of the album displayed below.

Many thanks

I've created a module to generate my own front page by a straight SQL select from several tables - the idea being partly because I wanted a completely different presentation, partly because I want a large number of articles actually visible on the front page, partly to avoid going through calls to hook_nodeapi etc. So far it has worked very well, and has seriously speeded up my front page presentation.

There is only one drawback: as it stands, it doesn't provide the URL alias links, only node links. So I want to modify the SQL to include the url_alias table. Here is the code (the "titles_settings" table belongs to my front-page module by the way):

select t.uid, f.filepath, f.filemime, t.display_name, t.which_column, t.weight, n.nid, n.title, n.created, n.body, n.teaser, n.sticky, u.dst AS path_alias from {titles_settings} t join {node} n on t.uid=n.uid left outer join {files} f on n.nid=f.nid LEFT JOIN {url_alias} u ON CONCAT('node/', n.nid) = u.src where ( n.status=1 and n.moderate=0 and n.promote=1) order by n.sticky desc, t.which_column, t.weight, t.uid, n.created DESC

This executes fine and produces the result I want. Only problem - it seemed to me that it would be better to have an index on url_alias.src in order to optimise the join, so I created one. But looking at the SQL statement with EXPLAIN I can see that the index is not being used.

Can anyone tell me the reason for this, and the reason for not indexing this field in the first place?

Hello,

I'm currently bugfixing my conversion of the Quotes modules to 4.7. One issue I had was with creating a form to use a GET request.

Essentially the form allows nodes to be sorted on a pages, so I considered that POST functionality -- and indeed the Forms API -- was inappropriate. Instead I'm using theme_select, theme_button etc directly, to allow themability rather than just spitting out HTML.

Hello,

I am about to finish my first module, which turned out to be nearly as big as system.module!

Unfortunately, I have very poor SQL skills. I haven't dealt with SQL directly in years.
So... well, I need some quick help with a query.
I have two tables. One is the normal "node" one:


+----------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+----------+------------------+------+-----+---------+----------------+
| nid | int(10) unsigned | | PRI | NULL | auto_increment |
| vid | int(10) unsigned | | MUL | 0 | |
| type | varchar(32) | | MUL | | |
| title | varchar(128) | | MUL | | |
| uid | int(10) | | MUL | 0 | |
| status | int(4) | | MUL | 1 | |
| created | int(11) | | MUL | 0 | |
| changed | int(11) | | MUL | 0 | |
| comment | int(2) | | | 0 | |
| promote | int(2) | | MUL | 0 | |
| moderate | int(2) | | MUL | 0 | |
| sticky | int(2) | | | 0 | |
