PluginUI

The Wiki Plugin UI allows end users to insert and edit wiki plugins without having to deal with the syntax details. To be supported, the plugin must define the wikiplugin wikiplugin_*_info function (ex: wikiplugin_annotation_info). The function is a replacement to the _help function previously used. Instead of returning a string with documentation, it returns an array of information about the plug-in.

When the function is available, the plugin help description is also auto-generated.

The info function also provides preferences to be validated. The prefs property is an array of preferences that need to have the 'y' value. Failure on any of the preferences will cause the plugin to be disabled. A unique preference must be created for each plugin (in addition to feature checks). The preference must be created in lib/setup/prefs.php

The plugin will be manageable, along with all the other plugins, from the administration section. Go to "Plugins" tab under "Text area" administration page (tiki-admin.php?page=textarea).

Annotation sample
<?php

function wikiplugin_annotation_info() {
	return array(
		'name' => tra('Image Annotation'),
		// link to plugin documentation page on doc.tiki.org (in this case http://doc.tiki.org/PluginAnnotation)
		'documentation' => 'PluginAnnotation',
		'description' => tra("Displays an image and enables users to define zones to highlight information on the image."),
		// list of preferences that need to be enabled to use the plugin
		'prefs' => array('wikiplugin_annotation'),
		'body' => tra('Autogenerated content. Leave blank initially.'),
		'filter' => 'striptags',
		'params' => array(
			'src' => array(
				'required' => true,
				'name' => tra('Location'),
				'description' => tra('Absolute URL to the image or relative path from tiki root.'),
				'filter' => 'url',
			),
			'width' => array(
				'required' => true,
				'name' => tra('Width'),
				'description' => tra('Image width.'),
				'filter' => 'digits',
			),
			'height' => array(
				'required' => true,
				'name' => tra('Height'),
				'description' => tra('Image height.'),
				'filter' => 'digits',
			),
			'align' => array(
				// if true, this plugin field is mandatory
				'required' => false,
				// field name
				'name' => tra('Alignment'),
				'description' => tra('Image alignment'),
				'filter' => 'alpha',
				// if advanced equals true, this field is hidden by default and only visible inside "Advanced options" section
				'advanced' => true,
				// Field is a select box with the following options instead of a text field
				'options' => array(
					array('text' => tra('Left'), 'value' => 'left'), 
					array('text' => tra('Right'), 'value' => 'right'), 
					array('text' => tra('Center'), 'value' => 'center'), 
				),
			),
		)
	);
}

Plugin UI development

While the current plugin UI allows defining easily some plugins, some more advanced plugins could use new features.

For example, the FILE plugin is as of Tiki 5 complicated, having 7 parameters: name, desc, page, showdesc, image, fileId and date. If used for Wiki attachments, only the first 5 are used, while if used for files from the galleries, only the last 2 parameters are used. This plugin would ideally have 2 radio buttons to choose between a file from the galleries and an attachment. If it's from the galleries, only the first 5 parameters should show, name being required, otherwise only the last 2, fileId being required.

Desired features:

  • Parameters with radio buttons or checkboxes for boolean fields.
  • Dynamic display of parameters depending on the value of other parameters.
  • Parameters becoming required or not depending on the value of others parameters.


Below is a proposal of the interface to implement the new functionalities described above. Note that only properties relevant to this discussion were included.

Annotation sample
function wikiplugin_file_info()
{
	return array(
		'params' => array(
			/* This is a select box with two options 'Wiki page attachment' and 'File from file gallery'.
			 * Note that other params set values of this one as their parent meaning that they will only be
			 * displayed if this value is selected (they are hidden by default) */
			'type' => array(
				'required' => true,
				'name' => tra('Type'),
				'options' => array(
					array('text' => tra('Wiki page attachment'), 'value' => 'attachment'),
					array('text' => tra('File from file gallery'), 'value' => 'gallery'),
				),
			),
			/* Although this field is set as required, since it has a parent it will only be 
			 * considered as required if the value from 'type' field is selected.
			 * Otherwise the field is not even displayed and not considered as required.
			 * The 'parent' key is an array with two values. The 'name' value is the
			 * name of the parent parameter and 'value' is the value that must be selected on
			 * the parent param for this field to be displayed.*/
    			'name' => array(
				'required' => true,
				'name' => tra('Name'),
				'description' => tra('Wiki attachment:') . ' ' . tra("Gives the name of the attached file to link to"),
				'parent' => array('name' => 'type', 'value' => 'attachment'),
			),
	    		'page' => array(
				'required' => false,
				'name' => tra('Page'),
				'parent' => array('name' => 'type', 'value' => 'attachment'),
			),
			'showdesc' => array(
				'required' => false,
				'name' => tra('Show attachment description'),
				'parent' => array('name' => 'type', 'value' => 'attachment'),
				// New field type bool that automatically generates a checkbox
				'type' => 'bool',
			),
			'fileId' => array(
				'required' => true,
				'name' => tra('File identifier'),
				'filter' => 'digits',
				'parent' => array('name' => 'type', 'value' => 'gallery'),
			),
		)
	);
}

Keywords

The following is a list of keywords that should serve as hubs for navigation within the Tiki development and should correspond to documentation keywords.

Each feature in Tiki has a wiki page which regroups all the bugs, requests for enhancements, etc. It is somewhat a form of wiki-based project management. You can also express your interest in a feature by adding it to your profile. You can also try out the Dynamic filter.
