After the * entry was successfuly created, bolink::link($app,$new_id,$arr) has to be called to create the links! * - link-list: Widget to show the links to an entry in a table with an unlink icon for each link. Needs the same * pair of variables as link-to widget and needs to have the same id, as the data is shared with link-to. * - link-string: comma-separated list of link-titles with a link to its view method, value is like get_links() * or array with keys to_app and to_id (widget calls then get_links itself) * - link-add: Add a new entry of the select app, which is already linked to a given entry * - link-entry: Allow to select an entry of a selectable or in options specified app * - link-apps: Select an app registered in the link system, options: '' or 'add' * *<code> * $content[$name] = array( * 'to_app' => // I string appname of the entry to link to * 'to_id' => // IO int id of the entry to link to, for new entries 0, returns the array with new links * // the following params apply only for the link-to widget! * 'no_files' => // I boolean suppress attach-files, default no * 'show_deleted' => // I Show links that are marked as deleted, being held for purge * 'search_label' => // I string label to use instead of search * 'link_label' => // I string label for the link button, default 'Link' * // optional only for the link-add widget and link-entry widget * 'extra' => // I array with extra parameters, eg. array('cat_id' => 15), or string to add in onclick search for link-entry * //eg. ",values2url(this.form,'start,end,duration,participants,recur_type,whole_day')" * 'query' => // I preset for the query * 'current' => // I currently select id * // optional for link-string: * 'only_app' => // I string with appname, eg. 'projectmananager' to list only linked projects * 'link_type' => // I string with sub-type key to list only entries of that type * ); *</code> * * This widget is independent of the UI as it only uses etemplate-widgets and has therefore no render-function. */ class link_widget { /** * @var array exported methods of this class */ var $public_functions = array( 'pre_process' => True, 'post_process' => True, ); /** * @var array availible extensions and there names for the editor */ var $human_name = array( 'link' => 'Link', 'link-to' => 'LinkTo', 'link-list' => 'LinkList', 'link-string' => 'LinkString', 'link-add' => 'LinkEntry', 'link-entry' => 'Select entry', 'link-apps' => 'LinkApps', ); /** * @var boolean $debug switches debug-messages on and off */ var $debug = False; /** * Flag that ajax_search needs to add onchange line * */ const AJAX_NEED_ONCHANGE = 987; /** * Limit display of links to given number to not run into memory_limit for huge number of links */ const LIMIT_LINKS = 1000; /** * Constructor of the extension * * @param string $ui '' for html */ function link_widget($ui='') { } /** * pre-processing of the extension * * This function is called before the extension gets rendered * * @param string $name form-name of the control * @param mixed &$value value / existing content, can be modified * @param array &$cell array with the widget, can be modified for ui-independent widgets * @param array &$readonlys names of widgets as key, to be made readonly * @param mixed &$extension_data data the extension can store persisten between pre- and post-process * @param object &$tmpl reference to the template we belong too * @return boolean true if extra label is allowed, false otherwise */ function pre_process($name,&$value,&$cell,&$readonlys,&$extension_data,&$tmpl) { $extension_data['type'] = $type = $cell['type']; $extension_data['needed'] = $cell['needed']; $help = $cell['help'] ?
