+= Custom Ticket Fields =
+Trac supports adding custom, user-defined fields to the ticket module. Using custom fields, you can add typed, site-specific properties to tickets.
+
+== Configuration ==
+Configuring custom ticket fields is done in the [wiki:TracIni trac.ini] file. All field definitions should be under a section named `[ticket-custom]`.
+
+The syntax of each field definition is:
+{{{
+ FIELD_NAME = TYPE
+ (FIELD_NAME.OPTION = VALUE)
+ ...
+}}}
+The example below should help to explain the syntax.
+
+=== Available Field Types and Options ===
+ * '''text''': A simple (one line) text field.
+   * label: Descriptive label.
+   * value: Default value.
+   * order: Sort order placement. (Determines relative placement in forms.)
+ * '''checkbox''': A boolean value check box.
+   * label: Descriptive label.
+   * value: Default value (0 or 1).
+   * order: Sort order placement.
+ * '''select''': Drop-down select box. Uses a list of values.
+   * label: Descriptive label.
+   * options: List of values, separated by '''|''' (vertical pipe).
+   * value: Default value (Item #, starting at 0).
+   * order: Sort order placement.
+ * '''radio''': Radio buttons. Essentially the same as '''select'''.
+   * label: Descriptive label.
+   * options: List of values, separated by '''|''' (vertical pipe).
+   * value: Default value (Item #, starting at 0).
+   * order: Sort order placement.
+ * '''textarea''': Multi-line text area.
+   * label: Descriptive label.
+   * value: Default text.
+   * cols: Width in columns.
+   * rows: Height in lines.
+   * order: Sort order placement.
+
+=== Sample Config ===
+{{{
+[ticket-custom]
+
+test_one = text
+test_one.label = Just a text box
+
+test_two = text
+test_two.label = Another text-box
+test_two.value = Just a default value
+
+test_three = checkbox
+test_three.label = Some checkbox
+test_three.value = 1
+
+test_four = select
+test_four.label = My selectbox
+test_four.options = one|two|third option|four
+test_four.value = 2
+
+test_five = radio
+test_five.label = Radio buttons are fun
+test_five.options = uno|dos|tres|cuatro|cinco
+test_five.value = 1
+
+test_six = textarea
+test_six.label = This is a large textarea
+test_six.value = Default text
+test_six.cols = 60
+test_six.rows = 30
+}}}
+
+''Note: To make entering an option for a `select` type field optional, specify a leading `|` in the `fieldname.options` option.''
+
+=== Reports Involving Custom Fields ===
+
+The SQL required for TracReports to include custom ticket fields is relatively hard to get right. You need a `JOIN` with the `ticket_custom` field for every custom field that should be involved.
+
+The following example includes a custom ticket field named `progress` in the report:
+{{{
+#!sql
+SELECT p.value AS __color__,
+   id AS ticket, summary, component, version, milestone, severity,
+   (CASE status WHEN 'assigned' THEN owner||' *' ELSE owner END) AS owner,
+   time AS created,
+   changetime AS _changetime, description AS _description,
+   reporter AS _reporter,
+  (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
+  FROM ticket t
+     LEFT OUTER JOIN ticket_custom c ON (t.id = c.ticket AND c.name = 'progress')
+     JOIN enum p ON p.name = t.priority AND p.type='priority'
+  WHERE status IN ('new', 'assigned', 'reopened')
+  ORDER BY p.value, milestone, severity, time
+}}}
+
+Note in particular the `LEFT OUTER JOIN` statement here.
