Comment from Steven: It does this by redirecting the submission of the form to a hidden <iframe> when you click "Attach" (we cannot submit data through Ajax directly because you cannot read file contents from JS for security reasons). Once the file is submitted, the upload-section of the form is updated. Things to note:
* The feature degrades back to the current behaviour without JS.
* If there are errors with the uploaded file (disallowed type, too big, ...), they are displayed at the top of the file attachments fieldset.
* Though the hidden-iframe method sounds dirty, it's quite compact and is 100% implemented in .js files. The drupal.js api makes it a snap to use.
* I included some minor improvements to the Drupal JS API and code.
* I added an API drupal_call_js() to bridge the PHP/JS gap: it takes a function name and arguments, and outputs a <script> tag. The kicker is that it preserves the structure and type of arguments, so e.g. PHP associative arrays end up as objects in JS.
* I also included a progressbar widget that I wrote for drumm's ongoing update.php work. It includes Ajax status updating/monitoring, but it is only used as a pure throbber in this patch. But as the code was already written and is going to be used in the near future, I left that part in. It's pretty small ;). If PHP supports ad-hoc upload info in the future like Ruby on Rails, we can implement that in 5 minutes.
part of the node system! If you have a module that implements node
types, you'll have to udpate its CVS HEAD version.
We replaced _node_name() and _node_types() by _node(). The new _node()
hook let's you define one or more node types, including their names.
The implementation of the _node() hook needs to:
return array($type1 => array('name' => $name1, 'base' => $base1),
$type2 => array('name' => $name2, 'base' => $base2));
where $type is the node type, $name is the human readable name of the type
and $base is used instead of <hook> for <hook>_load, <hook>_view, etc.
For example, the story module's node hook looks like this:
function story_node() {
return array('story' => array('name' => t('story'), 'base' => 'story'));
}
The page module's node hook module like:
function page_node() {
return array('page' => array('name' => t('page'), 'base' => 'page'));
}
However, more complex node modules like the project module and the
flexinode module can use the 'base' parameter to specify a different base.
The project module implements two node types, proejcts and issues, so it
can do:
function project_node() {
return array(
array('project_project' => array('name' => t('project'), 'base' => 'project'),
array('project_issue' => array('name' => t('issue'), 'base' => 'project_issue'));
}
In the flexinode module's case there can only one base ...
This hook will simplify the CCK, and will make it easy (or easier) to merge
the story and page module.
In addition, node_list() became node_get_types(). In addition, we created
the following functions: node_get_name($type) and node_get_base($type).
list_themes() sorts the results by name. This uses filesort in MySQL since there aren't any indexes. Sorting is not used except in system_user(). This one use can be handled with ksort since it is not often executed (only on the user edit screen when multiple themes are enabled).
And a one line fix to remove a variable in system_user() is in here too.
Note: I also (mostly) unified the tags to use the "// ID" form instead of "/* ID */", but that's more of a cosmetic issue. I'm not sure whether *.txt files and the stuff in themes/ need tags(?).
"This function is called in one place, so it can be rolled into the calling function. The return value isn't used so we can remove handling of it. This is executed for every non-cached page view, so the smaller code should save a smallish ammount of memory and time."
