Chris@76 17 /* This is perhaps the most important and probably most accessed files in all
Chris@76 18 of SMF. This file controls topic, message, and attachment display. It
Chris@76 19 does so with the following functions:
Chris@76 20
Chris@76 21 void Display()
Chris@76 22 - loads the posts in a topic up so they can be displayed.
Chris@76 23 - supports wireless, using wap/wap2/imode and the Wireless templates.
Chris@76 24 - uses the main sub template of the Display template.
Chris@76 25 - requires a topic, and can go to the previous or next topic from it.
Chris@76 26 - jumps to the correct post depending on a number/time/IS_MSG passed.
Chris@76 27 - depends on the messages_per_page, defaultMaxMessages and enableAllMessages settings.
Chris@76 28 - is accessed by ?topic=id_topic.START.
Chris@76 29
Chris@76 30 array prepareDisplayContext(bool reset = false)
Chris@76 31 - actually gets and prepares the message context.
Chris@76 32 - starts over from the beginning if reset is set to true, which is
Chris@76 33 useful for showing an index before or after the posts.
Chris@76 34
Chris@76 35 void Download()
Chris@76 36 - downloads an attachment or avatar, and increments the downloads.
Chris@76 37 - requires the view_attachments permission. (not for avatars!)
Chris@76 38 - disables the session parser, and clears any previous output.
Chris@76 39 - depends on the attachmentUploadDir setting being correct.
Chris@76 40 - is accessed via the query string ?action=dlattach.
Chris@76 41 - views to attachments and avatars do not increase hits and are not
Chris@76 42 logged in the "Who's Online" log.
Chris@76 43
Chris@76 44 array loadAttachmentContext(int id_msg)
Chris@76 45 - loads an attachment's contextual data including, most importantly,
Chris@76 46 its size if it is an image.
Chris@76 47 - expects the $attachments array to have been filled with the proper
Chris@76 48 attachment data, as Display() does.
Chris@76 49 - requires the view_attachments permission to calculate image size.
Chris@76 50 - attempts to keep the "aspect ratio" of the posted image in line,
Chris@76 51 even if it has to be resized by the max_image_width and
Chris@76 52 max_image_height settings.
Chris@76 53
Chris@76 54 int approved_attach_sort(array a, array b)
Chris@76 55 - a sort function for putting unapproved attachments first.
Chris@76 56
Chris@76 57 void QuickInTopicModeration()
Chris@76 58 - in-topic quick moderation.
