Drupal 7.x

I have my site up and running great with Drupal 7 (pencilpapercomputer.com) but I'm having some trouble figuring out how to modify the page navigation links. The current page navigation has Previous/Next links that display like

pencilpapercomputer.com/blog?page=1,

but I want page navigation links to display like

pencilpapercomputer.com/blog/insert-title-here.

I am really stumped, if I make an entry for 100 litres I need need a way for it to be converted to US Gallons, and then appended along side the litre value, or vice versa. e.g. "100L | 26.42 Gal" should be the result.

Hi,
I've created a form and themed it as a table using D7 form API.
I want to add a 'delete' button to each row that will remove the row on which the button was clicked (via Ajax - w/o page refresh).

My problem is: how to determine inside the Ajax callback function which row was clicked?
Each row had a unique id, each button has a unique name and id, I can see in the $form_state that there is an entry called: "_triggering_element_name" which contains the name of the clicked button, but somehow it doesn't seem to be a the correct way to do it...

some code:

// form build
function form_build {
...
for ($i ... ) {
$form['items']["delete$i"] = array(
'#type' => 'submit',
'#name' => "remove$i",
'#value' => t('Delete'),
'#submit' => array('myform_del_item'),
'#ajax' => array(
'callback' => 'mymodule_form_callback_items',
'wrapper' => 'item-div',
'effect' => 'fade',
'progress' => array('type' => 'none'),
),
);
}
}

/**
* only select the portion of the form to be updated.
*/
function mymodule_form_callback_items($form, $form_state) {
return $form['items'];
}

/**
* Submit handler for the "delete" button.
*/
function myform_del_item($form, &$form_state) {
// 1. get row id / button id ???
// 2. delete row

Hi, I cannot find any tutorial how to use #theme and #theme_wrappers keys of Form API. I found only explanations how to use theme functions assigned to whole form. Can I send some additional arguments to theme functions? In particular,
I want to create table inside fieldset.
I tried this:

Hi all,
