META -- displays meta-data

  • Provided mainly for use in templates, this variable generates the parts of the topic view that relate to meta-data (attachments, forms etc.) The formfield item is the most likely to be useful to casual users.
  • Syntax: %META{ "item" ...}%
  • Parameters:
    Item Options Description
    "formfield" name="...": name of the field. The field value can be shortened as described in FormattedSearch for $formfield.
    newline="...": by default, each newline character will be rewritten to <br /> to allow metadata that contains newlines to be used in tables, etc. $n indicates a newline character.
    bar="...": by default, each vertical bar is rewritten to an HTML entity so as to not be mistaken for a table separator.
    encode="type": have the value encoded in the specified type. Possible types are the same as ENCODE's. If this is specified, newline and bar options are ignored.
    topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%".
    Show a single form field
    "form" topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%". Generates the table showing the form fields. See Form Templates
    "attachments" all="on" to show hidden attachments.
    title="..." to show a title - only if attachments are displayed.
    template="..." to use a custom template for the rendering of attachments; default attachtables is used.
    topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%".
    Generates the list of attachments
    "moved" topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%". Details of any topic moves
    "parent" dontrecurse="on": By default recurses up tree, this has some cost.
    nowebhome="on": Suppress WebHome.
    prefix="...": Prefix that goes before parents, but only if there are parents, default "".
    format="...": Format string used to display each parent topic where $web expands to the web name, and $topic expands to the topic name; default: "[[$web.$topic][$topic]]"
    suffix="...": Suffix, only appears if there are parents; default "".
    separator="...": Separator between parents; default " > ".
    topic="...": Get meta info of "Topic" or "Web.Topic"; default "%BASEWEB%.%BASETOPIC%".
    Generates the parent link
  • Attention: The base topic, not the current topic, is used if %META{}% is placed in an included topic. Add a topic="%WEB%.%TOPIC%" parameter if you need meta info of the current topic.
  • Note: Formatting tokens can be used for newline, prefix, format, suffix and separator options, such as separator="$n   * "
