VarMETA < TWiki

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 * "
