/* This is perhaps the most important and probably most accessed files in all
|
|
of SMF. This file controls topic, message, and attachment display. It
|
|
does so with the following functions:
|
|
|
|
void Display()
|
|
- loads the posts in a topic up so they can be displayed.
|
|
- supports wireless, using wap/wap2/imode and the Wireless templates.
|
|
- uses the main sub template of the Display template.
|
|
- requires a topic, and can go to the previous or next topic from it.
|
|
- jumps to the correct post depending on a number/time/IS_MSG passed.
|
|
- depends on the messages_per_page, defaultMaxMessages and enableAllMessages settings.
|
|
- is accessed by ?topic=id_topic.START.
|
|
|
|
array prepareDisplayContext(bool reset = false)
|
|
- actually gets and prepares the message context.
|
|
- starts over from the beginning if reset is set to true, which is
|
|
useful for showing an index before or after the posts.
|
|
|
|
void Download()
|
|
- downloads an attachment or avatar, and increments the downloads.
|
|
- requires the view_attachments permission. (not for avatars!)
|
|
- disables the session parser, and clears any previous output.
|
|
- depends on the attachmentUploadDir setting being correct.
|
|
- is accessed via the query string ?action=dlattach.
|
|
- views to attachments and avatars do not increase hits and are not
|
|
logged in the "Who's Online" log.
|
|
|
|
array loadAttachmentContext(int id_msg)
|
|
- loads an attachment's contextual data including, most importantly,
|
|
its size if it is an image.
|
|
- expects the $attachments array to have been filled with the proper
|
|
attachment data, as Display() does.
|
|
- requires the view_attachments permission to calculate image size.
|
|
- attempts to keep the "aspect ratio" of the posted image in line,
|
|
even if it has to be resized by the max_image_width and
|
|
max_image_height settings.
|
|
|
|
int approved_attach_sort(array a, array b)
|
|
- a sort function for putting unapproved attachments first.
|
|
|
|
void QuickInTopicModeration()
|
|
- in-topic quick moderation.
|
