Development:Block formslib
(This is currently a proposal and isn't available for use see [https://tracker.moodle.org/browse/MDL-9641 MDL-9641]).
Overview
The block formslib functions are designed to allow developers easily create forms for their blocks. Please read Development:lib/formslib.php for full details about using formslib.
Creating a Global Configuration form
In order to create a global confuration form using formslib, you must create a file /blocks/BLOCKNAME/config_global_form.php
In this file a class needs to be created which follows the naming scheme: block_BLOCKNAME_config_global_form and extends block_config_global_form
In your form configuration class you need to implement the block_configuration() method. Elements added will automatically saved in $CFG.
require_once $CFG->dirroot .'/blocks/block_config_global_form.php'; class block_BLOCKNAME_config_global_form extends block_config_global_form { function block_configuration(&$mform){ // add a html editor text field named block_BLOCKNAME_text $mform->addElement('htmleditor', 'block_BLOCKNAME_text', get_string('text','BLOCKNAME')); // This will set the default value of the textfield to 'mydefaultstring'. (If $CFG->textfield // exsts, it will be set to that when the form is loaded) $mform->setDefault('mydefaultstring'); $mform->setType('block_BLOCKNAME_text', PARAM_RAW); $mform->addElement('text', 'block_BLOCKNAME_num', get_string('block_BLOCKNAME_num', 'BLOCKNAME')); $mform->setDefault('block_online_users_timetosee', '5'); // Add client side validation which forces the field as numeric $mform->addRule('block_BLOCKNAME_num', null, 'numeric', null, 'client'); $mform->setType('block_BLOCKNAME_num', PARAM_INT); } }
Creating a Instance Configuration form
In order to create a global confuration form using formslib, you must create a file /blocks/BLOCKNAME/config_instance_form.php
In this file a class needs to be created which follows the naming scheme: block_BLOCKNAME_config_instance_form and extends block_config_instance_form.
In your form configuration class you need to implement the instance_configuration() method. Elements added will automatically saved in $block->config
<?php require_once $CFG->dirroot .'/blocks/block_config_instance_form.php'; class block_BLOCKNAME_config_instance_form extends block_config_instance_form { function instance_configuration(&$mform){ // add a text field named title $mform->addElement('text','title',get_string('configtitle', 'BLOCKNAME')); // this will set the form field to 'my title' // (if a title string is already stored in the block instance // configuration, it will automatically be set it to that) $mform->setDefault('title', 'my title string'); $mform->setType('title', PARAM_NOTAGS); } }
