Module development and code questions

I've created a new feature for flexinode tables. When you define a drop-down select menu, you can specify whether that menu should "filter in table". If this option is set, the table view for that flexinode type will have a filter widget above it which can be used to reduce the selection in the table accordingly. Multiple filter widgets are possible.

There is a demonstration here:

Hi , i am working on a module to provide redirection of a user on login to the page he was at or perhaps the page he was going to . Which hook should i use to set a variable holding the value of the current page?

I am looking to do something similar to what is done with this forum module. I have written (with the help of this forum) a small module for use on my site. I need to show a larger table than my theme allows. I would like to "turn off" the right side blocks when this module is called and allow the center block to use that area so that essentially while in that module the template changes from a 3 column to a two column display.

I hope this makes sense. Any help as always is appreciated.

I am having a trouble developing a module. In my hook_init() function, I call both the function drupal_get_path, and theme_add_style. Whenever I am logged into the admin user account, everything works fine, but when I am anonymous, it comes up with a fatal error because it can't find either function. In drupal 4.6, I can call require_once("includes/common.inc"), but in 4.7, theme_add_style is not found still.

Hello,

Well, this has been brought up a few times before, but I think my case is a little different.
I developed node_article.module. Now, I need to make it work with our own magazine!

At Free Software Magazine, we use our own article format for a number of reasons (the main one being automatic composition). An example of an article is at the bottom of this message.

Now, here is what I need to do:

1) Create a new filter which transforms the XML below into HTML

2) Create a new input format which uses the above filter

3) Make this filter available ONLY for node_article nodes

4) Make this filter the ONLY option for node_article nodes

Why 3)? Well, because in the site I will also have blogs, and probably won't want people to input their blogs using the article format.
Why 4)? Because I definitely won't want authors to hand in articles in any other format

For what I see, the input format is set by role, rather than node type. Is this _always_ the case? If the answer is "yes", then I'll need to hack node_article so that it only accepts a specific input type. But this won't solve 3) (that is, a person who is a blogger AND an author will be able to hand in blogs using the article format).

Any ideas about this one?

Thanks a million!

Example of an article:

<article>

<contents>

<p>This is the article's introduction. This paragraph will display as a blurb on the home page or wherever else the article will display. It's crucial to make this section interesting, so that your readers won't stop reading the article.</p>

Hello,

I wrote node_article.module, a complete module that manages an article's workflow with author, editor, editor in chief and copyeditor. Everybody a part from chief and author are optional.

It's been created to work well while creating Free Software Magazine.
