  29. * simply increments them.

  32. * moved, removed or split. parameter1 is the topicid, parameter2 is the new subject
  33. *
  34. * 'postgroups' case updates those members who match condition's
  35. * post-based membergroups in the database (restricted by parameter1).

  793. - unparsed_equals_content: [tag=...]unparsed content[/tag]
  794. parameters: an optional array of parameters, for the form
  795. [tag abc=123]content[/tag]. The array is an associative array
  796. where the keys are the parameter names, and the values are an
  797. array which may contain the following:
  798. - match: a regular expression to validate and match the value.
  799. - quoted: true if the value should be quoted.
  800. - validate: callback to evaluate on the data, which is $data.
  801. - value: a string in which to replace $1 with the data.
  802. either it or validate may be used, not both.
  803. - optional: true if the parameter is optional.
  804. test: a regular expression to test immediately after the tag's
  805. '=', ' ' or ']'. Typically, should have a \] at the end.
  806. Optional.
  807. content: only available for unparsed_content, closed,
  808. unparsed_commas_content, and unparsed_equals_content.
  809. $1 is replaced with the content of the tag. Parameters
  810. are replaced in the form {param}. For unparsed_commas_content,
  811. $2, $3, ..., $n are replaced.
  812. before: only when content is not used, to go before any
  813. content. For unparsed_equals, $1 is replaced with the value.
  814. For unparsed_commas, $1, $2, ..., $n are replaced.
  815. after: similar to before in every way, except that it is used
  816. when the tag is closed.
  817. disabled_content: used in place of content when the tag is
  818. disabled. For closed, default is '', otherwise it is '$1' if
  819. block_level is false, '<div>$1</div>' elsewise.
  820. disabled_before: used in place of before when disabled. Defaults
  821. to '<div>' if block_level, '' if not.
  822. disabled_after: used in place of after when disabled. Defaults
  823. to '</div>' if block_level, '' if not.
  824. block_level: set to true the tag is a "block level" tag, similar
  825. to HTML. Block level tags cannot be nested inside tags that are
  826. not block level, and will not be implicitly closed as easily.
  827. One break following a block level tag may also be removed.
  828. trim: if set, and 'inside' whitespace after the begin tag will be
  829. removed. If set to 'outside', whitespace after the end tag will
  830. meet the same fate.
  831. validate: except when type is missing or 'closed', a callback to
  832. validate the data as $data. Depending on the tag's type, $data
  833. may be a string or an array of strings (corresponding to the
  834. replacement.)
  835. quoted: when type is 'unparsed_equals' or 'parsed_equals' only,
  836. may be not set, 'optional', or 'required' corresponding to if
  837. the content may be quoted. This allows the parser to read
  838. [tag="abc]def[esdf]"] properly.
  839. require_parents: an array of tag names, or not set. If set, the
  840. enclosing tag *must* be one of the listed tags, or parsing won't
  841. occur.
  842. require_children: similar to require_parents, if set children
  843. won't be parsed if they are not in the list.
  844. disallow_children: similar to, but very different from,
  845. require_children, if it is set the listed tags will not be
  846. parsed inside the tag.
  847. parsed_tags_allowed: an array restricting what BBC can be in the
  848. parsed_equals parameter, if desired.
