Render All visible Chapters from a specific Book.

Uses "listChapter" template key. ie. $CHAPTER_TEMPLATE[---TEMPLATE --]['listChapters']

{BOOK_CHAPTERS: name=book-sef-url}

{BOOK_CHAPTERS: name=book-sef-url&template=xxxxx&limit=3}

$parm['name']

$parm['template'] - $tmplKey = varset($parm['template'],'panel');

$parm['class']

Render All visible Menus from a specific chapter. Very often used for portfolio on homepage.

{CHAPTER_MENUS: name=chapter-sef-url}

{CHAPTER_MENUS: name=chapter-sef-url&template=xxxxx}

$parm['name']

$parm['template'] - overrides value ['menu_template']

$parm['class']

$parm['active']

$parm['limit']

Example for 2 cycles:

{CHAPTER_MENUS: name=portfolio&template=portfolio}
{CHAPTER_MENUS: name=portfolio&template=portfolio-modal}

 {CMENU=feature-1}

Renders a menu called 'feature-1' as found in the e107_page table

 Templating:  template key "nav" +  'showPage' in chapter_template.php

 Using:

- in Menu Manager: the only caption can be set, it always displayed all chapters + pages  (template nav is used), but shortcode is used for rendering (good)

- as a shortcode: - 

{PAGE_NAVIGATION: template=navdoc&auto=1}
{PAGE_NAVIGATION: chapter=4}
{PAGE_NAVIGATION: book=3&pages=true}

this shortcode uses e_sitelinks addon 

 Templating:  template key "panel" in chapter_template.php

 Using:

- in Menu Manager: the only caption can be set, it always displayed all chapters with template panel

- as a shortcode: - parameter book is available, so you can display only chapters/pages from one book, but again, chapters have to have template "panel" 

It has no logic...  not mention you need to know book ID . And there is hardcoded 24 items limit.

Example:

{MENU: path=page/chapter&book=7}

You can display only chapter shortcodes. No page/menus list. 

Next notice: as soon as you use panel template for book, this menu will fail.

 The menu is not working, see the issue

Retrieve all plugin's preferences:

$plugPrefs = e107::getPlugConfig('your_plugin')->getPref();

for using in class:

private $plugPrefs = array();
$this->plugPrefs = $plugPrefs; 

Another way:

$plugPrefs= e107::pref('your_plugin');

Retrieve single plugin preference:

$perPage = e107::pref('your_plugin', 'your_preference');

Update one preference:

To save new value:

e107::getPlugConfig('your_plugin')->set('your_preference', $addonsList)->save(true);

save(true) - value will be replaced
save(false) - value will be added

empty array:

e107::getPlugConfig('visualbuilder')->set('visualbuilder', array())->save(true);

 Just some

Example (from shortcode):

$e107cache = e107::getCache();

if($cacheData = $e107cache->retrieve('your_code'))
{
return $cacheData;
}

$cache_data = '';

$cache_data = $text;

$e107cache->set('your_code', $cache_data);
return $cache_data;

define('LW_CACHE_ENABLE', FALSE);

define('LW_CACHE_TAG', 'nomd5_linkwords');

if(LW_CACHE_ENABLE && ($temp = e107::getCache()->retrieve_sys(LW_CACHE_TAG))) {}

if(!vartrue($temp)) // Either cache disabled, or no info in cache (or error reading/processing cache)
{

}

Example:

public function afterUpdate($new_data, $old_data, $id)
{
e107::getCache()->clear("your_code");
}

Example:

define('LW_CACHE_TAG', 'nomd5_linkwords');

e107::getCache()->clear_sys(LW_CACHE_TAG);

public function afterCreate($new_data, $old_data, $id)
{
e107::getCache()->clear_sys(LW_CACHE_TAG);
// do something
}

public function afterUpdate($new_data, $old_data, $id)
{
e107::getCache()->clear_sys(LW_CACHE_TAG);
// do something
}


public function afterDelete($deleted_data, $id, $deleted_check)
{
e107::getCache()->clear_sys(LW_CACHE_TAG);

}

 $frm = e107::getForm();

 $text = $frm->hidden('name','value');

$ret = e107::getForm()->hidden('questionId',$field['questionId']);

How to load non-standard file names

 e107::lan('pcontent', "lan_content"); 

It is impossible (and useless) to rewrite old lang files, mainly if they are used for both areas (admin and front too). It would mean to rewrite each mention in other code too. I am not able to remember what way to use when, so I started to use this way (second parameter is file name inside languages/LANGUAGE/ folders)

How to get user Data

Example from old plugin

$sql5 = new db;
  $sql5->mySQLresult = @mysql_query("select * from ".MPREFIX."user where user_id='".intval($row4['news_com_author'])."';");
  $row5 = $sql5->db_fetch();
  $newscomauthor = $row5['user_name'];

Now:

$row5 = e107::user(intval($row4['news_com_author']));
  $newscomauthor = $row5['user_name'];

e107::user($user_id);
$userData = e107::user(); // Example - currently logged in user. 
$userData = e107::user(5); // Example  User ID #5.

TEXT FIELD

function form_text($form_name, $form_size, $form_value, $form_maxlength = FALSE, $form_class = "tbox form-control", $form_readonly = "", $form_tooltip = "", $form_js = "") {
...
	return "\n<input class='".$form_class."' type="text">";
}

function text($name, $value = '', $maxlength = 80, $options= array()) 
{
...
	return "<input type='".$type."' name="{$name}" value="{$value}">get_attributes($options, $name)." />";
}

$f->form_text($pname."_title", "40", $tp->toHTML($fi["title"]), "200", "form-control")

$frm->text($pname."_title", $tp->toHTML($fi["title"]),  "200", 'size=40&class=form-control')

$frm->text($pname."_googlemap",  $tp->toHTML($fi["googlemap"]), "200", "size=40&class=form-control&placeholder=".CUP_INFO_ADDRESS)

Textarea

function form_textarea($form_name, $form_columns, $form_rows, $form_value, $form_js = "", $form_style = "", $form_wrap = "", $form_readonly = "", $form_tooltip = "") {
...
		return "\n<textarea class="tbox form-control">".$form_value."</textarea>";

function textarea($name, $value, $rows = 10, $cols = 80, $options = array(), $counter = false) {
...
		return "<textarea>get_attributes($options, $name).">{$value}</textarea>".(false !== $counter ? $this->hidden('__'.$name.'autoheight_opt', $counter) : '');

$frm->form_textarea($pname."_info", "10", "20", $tp->toHTML($fi["info"]), "200", "form-control")

$frm->text($pname."_googlemap",  $tp->toHTML($fi["googlemap"]), "200", "size=40&class=form-control&placeholder=".CUP_INFO_ADDRESS)

Open form

$frm->form-open("post", e_SELF, $pname."_form", "", " class='form-horizontal'")

$frm->open($pname."_form",'post', null, array('class'=>'form-horizontal'))

form_open($form_method, $form_action, $form_name = "", $form_target = "", $form_enctype = "", $form_js = "")

Checkbox

function form_checkbox($form_name, $form_value, $form_checked = 0, $form_tooltip = "", $form_js = "") {
function checkbox($name, $value, $checked = false, $options = array())

Select

function form_option($form_option, $form_selected = "", $form_value = "", $form_js = "") {
...
return "\n";
}

function option($option_title, $value, $selected = false, $options = '')
return "";

How to get the value of one needed preference?

Example for the list of installed plugins:

$builder_pluglist = e107::getPref('plug_installed');

Where to find used core pref name?

In admin area: Tools / Database / Preferences Editor

How to manage core prefs from custom plugins

This is the way I have confirmed as working... 

$pref = e107::getPref();
$core_pref = e107::getConfig();

the form works with $pref

$core_pref->setPref($pref)->save(false, true);

if pref is multilanguage, it's a bit complicated according to admin/meta.php file 

How to change only one core pref

e107::getConfig('core')->setPref('prefnamet', $new_value);

/**
* Save object data to DB
*
* @param boolean $from_post merge post data
* @param boolean $force
* @param mixed $session_messages null: normal messages displayed, true: session messages used, false: no messages displayed. 
* @return boolean|integer 0 - no change, true - saved, false - error
*/

e107::getConfig('core')->save(true,false,false);

Not clear what $from_post means. With one pref true, with full $pref false?
