Another TracFormsPlugin Tutorial

Begin

This is the bare minimum (wiki) markup required to produce a form with TracForms syntax:

{{{
#!TracForm
[tf:mycheck] checked
}}}

Hereby you define a form with

• default settings, i.e. no field change tracking, standard submit button label
• one field
  • of default field type checkbox
  • with a label 'checked'

Diversify

When you go on designing your forms, you may wish to arrange and more-or-less beautify them.

This is fairly easy using TracWiki markup. The following examples show only a small subset of the possibilities, but simple and advanced tables are certainly among the dominating design elements. Use common sense when deciding on parameters like table border width or background color.

More form fields

Most probably you'll want to have multiple form fields.

The single most important rule is: Make sure, that you have unique field names within a form.

{{{
#!TracForm
choose combinations
|| ||a||b||c||
||1||[tf:check1a]||[tf:check1b]||[tf:check1c]||
||2||[tf:check2a]||[tf:check2b]||[tf:check2c]||
||3||[tf:check3a]||[tf:check3b]||[tf:check3c]||
}}}

rendered result:

How well does it scale? It has been proven to work for fairly large quantities of form fields.

I do use tickets with more than 120 checkboxes in one TracForm. --hasienda

Other field types

{{{
#!TracForm
[tf:mycheck] checked

[tf.input:myinput]

Like it? [tf.radio:mychoice true] Yes [tf.radio:mychoice false] No

[tf.select:myselect val0//(default) val1//label1 val2//label2]

Tell me more:[[BR]]
[tf.textarea:comment '(default comment)' 20 5]
}}}

rendered result:

Manage

Track changes

Two independent options allow to keep track of changes up to a certain degree:

track_fields

track field changes in this form, keeping a record for the last change time and author per field,
effect: setting this option will mostly enable you to use the [tf.who] and [tf.when] operations in your form

keep_history

keep a full change history record, starting from the time of setting this option,
effect: setting this option is mandatory to enable full form revision support including incremental change reset/rollback

Submit button label

{{{
#!TracForm
submit_label 'Track it!'
}}}

required to change the default submit button (possibly localized) label to any (fixed) label, see tutorial for use cases

Form-related operations

{{{
#!TracForm
form ID: [tf.form_id:]

ToDo:[[BR]]
[tf.textarea:comment '(default comment)' 20 5][[BR]]
last comment:
by [tf.form_updater:]
on [tf.form_updated_on:]
}}}

rendered result:
