etp::check_write_access (public)
etp::check_write_access
- Author:
- Luke Pond
- Created:
- 2001-08-29 Designed to be used at the top of every ETP admin page. Returns an HTTP 403 Access Denied and aborts page processing if the user doesn't have "write" permission for the current package.
- Partial Call Graph (max 5 caller/called nodes):
- Testcases:
- No testcase defined.
etp::define_application (public)
etp::define_application name params
TODO: Need documentation TODO: Check the parameters passed in
- Parameters:
- name (required)
- params (required)
- Partial Call Graph (max 5 caller/called nodes):
- Testcases:
- No testcase defined.
etp::define_content_type (public)
etp::define_content_type content_type pretty_name pretty_plural \
attribute_metadataCall this at server startup time to register the extended page attributes for a particular content type. It ensures that there is a corresponding entry in acs_object_types for the content type, and that for each of the extended page attributes given there is an appropriate entry in acs_attributes. Also, a namespace variable stores all extended page attributes in memory data structure for quick retrieval.
Extended page attribute values are stored in the acs_attribute_values table (so-called "generic" storage) to prevent the necessity of creating a table for each content type. This is the reason we're not using the attribute procs defined in the acs-subsite package, as they only support type-specific storage.
NOTE: get the attribute metadata right the first time. If you decide to add a new attribute to an existing object type, the procedure will create it for you. But it won't process updates to existing attributes or remove them. You'll have to do that by hand.
- Parameters:
- content_type (required)
- The content type you're registering. This name must be unique across all pages that must store extended page attributes.
- pretty_name (required)
- The display name for the content type
- pretty_plural (required)
- The plural form of the display name
- attribute_metadata (required)
- A list of records describing each extended page attribute. Each record is a list containing the following values (in sequence):
# TODO: other features are needed such as making an attribute optional # and also specifying options for select lists.
- attribute_name
- pretty_name
- pretty_plural
- datatype (must be one of the entries in acs_datatypes: string, boolean, number, integer, date, etc.)
- html (a string containing html attributes for the input control. useful attributes are "size=X" to specify the size of standard input controls, and "rows=X cols=X" to specify the size of a textarea. Textareas will be used only if the datatype is string and html specifies rows or cols.)
- default_value (can either be a string denoting a single default value, or the name of a callback function you've defined in the etp namespace which is used to provide values for select lists).

- Author:
- Luke Pond
- Created:
- 2001-05-31 If the current package is an instance of Edit This Page, and the user has write access, returns the html "Edit This Page" link which should be displayed at the bottom of the page.
This may be called either from your master template, or from individual pages that are used within an ETP package instance. It incurs 1 database hit to do the permissions check. The package type is acquired via the in-memory copy of the site-nodes layout.

etp::get_page_attributes (public)
etp::get_page_attributes [ -package_id package_id ]
- Switches:
- -package_id (optional)
- Returns:
- Creates the pa variable in the caller's context. Creates an array variable called pa in the caller's stack frame, containing all attributes necessary to render the current page. These attributes include the standard elements from the cr_revisions table such as title, description, and content. If the content_type parameter is provided, any extended page attributes that correspond to it will be included. See docs for etp::make_content_type to learn how this works.
Two database accesses are required to create the array variable. Once created, subsequent calls to this method will find the variable in a cache, unless a) any of the page attributes are changed, or b) the page has been flushed from the cache. (flush details TBD).
The complete list of standard attributes in the pa array is as follows:
- item_id
- name
- revision_id
- title
- context_bar
- context
- description
- publish_date
- content
- extended attributes, if any, defined by etp::make_content_type
