Description:
------------
just one example:
class test {
private static $_domain;
static member() {
add_settings_section(
self::$_namespace . '_location_options',
__('Location of your opensearch.xml file', self::$_domain),
function () { ?>
<p><?php _e('You can select location of your opensearch.xml file and his url, or leave automatic detection.', self::$_domain); ?></p>
<?php },
self::$_namespace . '_options_page'
);
}
}
and, this sample - not working.
I honestly do not understand, and therefore the PHP developers do not consider the closure, created by the code of methods of class, as a class method. But it is implicitly "import" $this.
Test script:
---------------
class test {
private static $_domain;
static test_member() {
add_settings_section( // wordpress API
self::$_namespace . '_location_options',
__('Location of your opensearch.xml file', self::$_domain),
function () { ?>
<p><?php _e('You can select location of your opensearch.xml file and his url, or leave automatic detection.', self::$_domain); ?></p>
<?php },
self::$_namespace . '_options_page'
);
}
}
