hook_form_alter

From what I understand, the proper place to put code to alter a form is in hook_form_alter. So I created a function mytheme_alpha_form_alter() and put it in template.php. Everything works fine, however the comments in template.php suggest that I should keep that file "as clean as possible" and to use the preprocess and process subfolders instead. So in trying to do things the proper alpha/omega way, I created a file preprocess/preprocess-page.inc and did the form modification code inside mytheme_alpha_preprocess_page(). This also works, but sure seems ugly.

Hej

Har skrivit en liten modul som med hjälp av hook_form_alter tar Taxanomiernas olika vokabulär och lägger dessa i två olika fieldsets istället för Taxanomiernas default fieldset, detta för att dela upp vokabulären i node_form-formuläret. Jag har tagit scroll-listorna som ligger i $form['taxonomy'], flyttat dessa till nya fieldsets och sedan dolt $form['taxonomy']. Detta fungerar lokalt och på en testserver men när modulen läggs upp på produktionsserver så fungerar det inte.

I need to give a seamless implementation of a site, where users can edit a number of bits of information about themselves. The Default form in content_profile is to add tabs (primary or secondary) to the /user/%uid pages. The content_profile_registration module does it right, it allows you to tick a box, and so add the fields to the registration form, using hook_form_alter, to add fields to the 'user_register' form.

Is there a module which does the same for the user_profile_form? or hook_user($op=form, $category=account);

I'm trying to add AHAH functionality inside a hook_form_alter() to be able to add an icon next to the block titles.

Here is how all this procedure works:

I am using Drupal's blog module to provide a lightweight electronic portfolio tool to students and teachers. I could use your feedback on the approach I've taken using content_access and hook_form_alter. Is this the best/safest way to do this? I still feel like a relative newbie to making these modifications.

For a fuller example of the reason for using blog as a portfolio, please see http://www.kassblog.com/item/1030

I added a checkbox field to the blog content type.

Only local images are allowed.

I'm replacing a single page from a contributed module. The page is currently rendered with a call to drupal_get_form() from a path like foo/%node/bar

My first thought was to replace the page with hook_form_alter, unset the form elements, and replace with my own content. But I thought that would require a whole lot of preprocessing on the form that I would just discard.

So, my next thought was to just redirect the path to my own function with hook_menu_alter. But, is this less efficient because of the dynamic nature of the path?

I'm just curious if anyone has experience with this.

hook_form_alter là một công cụ cực kỳ mạnh mà Drupal cung cấp. Chúng ta có thể sử dụng nó để thực hiện được nhiều việc, tưởng chừng như không thể: Thay đổi cấu trúc một form mà không cần sửa mã nguồn, định dạng form, thêm kịch bản xử lý cá nhân vào form hệ thống, ...
