Module development and code questions

I'm creating a module that dynamically generates webpages. It uses hook_menu to generate MENU_CALLBACKs which point to the function that creates the page. I've got two 'problems':

- I need to check if a path already exists. There is drupal_lookup_path() for aliases, but how do I check if another MENU_CALLBACK item hasn't already used this path?
- If I register a path with hook_menu, a node can still be placed at that same path. The dynamically generated page is not accessible more when that happens.

Hello. I hope this post is in the right area. My problem is I've succesfully embedded a flash/swf file into my page, but when I go to view it, I don't see the controls or the skin I uploaded. The video plays fine. All the files required are uploaded to my server in the appropriate directory. I've tried various ways of exporting the file from Flash 8 and I've searched for similar posts, none of these seem to have an answer either.

Please help! Thanks in Advance

Alright... I got this module originally from Brad Landis, so he deserve the credits.

His module was developed for 4.7, and he has no plan on making it 5.x compatible.

I am having problem with the serializing.. it seems like when the module tries to cache the Bible verse on the SQL, it gives error.

Anyways, you can see the errors if you visit my site.

I need to show a different taxonomy/term/id page depending on what term/id is being loaded. In my example, I want the taxonomy/term/id page to only show the node thumbnail if the term/id is from a certain content type. In order to accomplish this, I have manually hard coded the taxonomy_render_nodes function located in taxonomy.module.

Is there a better way to do this? Perhaps overriding somehow within the template.php or creating a module?

if you look at my site http://www.fansportsunion.com/fan/ you can see that I put the menu in the header I know how to move it around with in the header. But my problem is this - you can see that I have a banner in the header as well is there any way that I can Position the menu to the lower left and the banner in middle right of the header?

here is the code that I change to move it around

(1) I have a custom module that implements a node called 'odclass'.
(2) I create a form in odclass_form
(3) When presented, the form includes a taxonomy fieldset titled "Categories"
(4) I investigate and find this fieldset is created and added to the odclass menu in taxonomy_form_alter
(5) I try to remove the field in odclass_menu_alter, but taxonomy_form_alter is called AFTER odclass_form_alter.

Is there some way to signal that taxonomy_form_alter should not add to the form once odclass_form_alter has run?

THanks!
