^ Coordinator plugins
Switch to language: FR

History is a coordinator plugin, it brings some features related with user browsing history.

Plugin declaration

To activate History plugin, set indicate it into the [coordplugins] section.

history = 1

If you use several coordinator plugins, the order of the plugins declaration in the config file matters. See the documentation of coordinator plugins. Keep that in mind when declaring the History plugin.


History plugin records couples of actions/parameters.

To have 'myapp~default:index' taken into account and registered by the History plugin, you must ask it specifically with the help of $pluginParams into the controller.

By default no record is performed if you don't request it that way.

public $pluginParams = array(
    '*'     => array('history.add'=>false),
    'index' => array('history.add'=>true,
    'history.label'=>'Home', 'history.title'=>'Go to Homepage')
  • history.add (Boolean): If true allows to add a couple to the history
  • history.label (String): A name for this couple
  • history.title (String): A description for this couple


All the configuration parameters should be set into a [coordplugin_history] section of the configuration file (mainconfig.ini.php).

Size limit

The size of the History is limited to a certain number of couples (default is 10), this limit is customizable in the plugin parameters.

; max size of the history
maxsize = 20

Avoid duplicates

By default, History records couples one after another keeping the duplicates. If you wish the duplicates to be deleted from the History, you must set it in the parameters.

; if single = true then each page will be registered only once in history
; the latter will be retained.
single = true

Keep record of reloads

When you execute twice the same couple it is added only once. If you want the reloads to be visible in the History you must modify the 'double' parameter.

; If double = false pages will not appear twice a follow time in history.
double = false

Change attributes of a couple when executing

If you use only $pluginParams to declare the couples, you are soon limited for instance to modify the label according to the parameters.


We want to have the 'Page Hello' label for the value "foo" of a var parameter (myapp.com/index.php/myapp/default/index?var=foo) and we want to have the 'Page Bye' label for the value var. (myapp.com/index.php/myapp/default/index?var=bar).

If we use the basic declaration:

public $pluginParams = array(
        '*'     => array('history.add'=>false),
        'index' => array('history.add'=>true, 'history.label'=>'Page Hello')

we will have the same label 'Page Hello' for both URL.

To get what we want, we must write:

public $pluginParams = array(
        '*'     => array('history.add'=>false),
        'index' => array('history.add'=>true)

function index() {
    $rep = $this->getResponse('html');
    if( $this->param('var') !== null ) {
        $values = array('foo'=>'Hello', 'bar'=>'Bye');
        jApp::coord()->getPlugin('history')->change('label', 'Page '.$values[$this->param('var')]));
    $rep->body->assign('MAIN', $rep->body->fetch('myapp~page'));
    return $rep;

Use History to reload the page

One frequent case is: you want to execute an action (after a keystroke for example) and come back to the same page.

To perform this, History plugin provides a simple command.

$history = jApp::coord()->getPlugin('history');
return $history->reload( $this->getResponse('redirect') );

If you would like to reload the page modifying one or two parameters, you have just to do this:

$history = jApp::coord()->getPlugin('history');
$ret = $history->reload( $this->getResponse('redirect') );

$ret->params['foo'] = 'bar';

return $ret;

Use History to come back to previous page

Another frequent case is: get the link to come back to previous page.

$history = jApp::coord()->getPlugin('history');
return $history->back( $this->getResponse('redirect') );

Use History to know how long the internet user has been visiting the site

To get this, you must give parameters to the time and session_time_name variables, so that the entrance time on the site is recorded.

; if time = true a variable record time spent on site
time = true
; the name of this variable
session_time_name = "HISTORYTIME"

Then to catch the time spent on the site, you have just to do

$history = jApp::coord()->getPlugin('history');
$delais = $history->time();
