[英]WordPress - Fatal error: Call to a member function when calling class
I have created a php class in my theme function.php 我在主题函数function.php中创建了一个php类
class myWidgetSetting {
function get_title(){
//some blah blah code
}
}
$setting = new myWidgetSetting();
but when I call this class $setting->get_title()
inside: 但是当我在内部调用此类$setting->get_title()
:
class myWidget extends WP_Widget {
function renderLayout(){
global $setting;
$setting->get_title();
}
}
Then I get this error: 然后我得到这个错误:
Fatal error: Call to a member function get_title() on a non-object in D:\\wamp\\www\\wp-content\\themes\\twentyten\\widgets\\myWidget.php on line 3 致命错误:在第3行的D:\\ wamp \\ www \\ wp-content \\ themes \\ twentyten \\ widgets \\ myWidget.php中的非对象上调用成员函数get_title()
Do i need to register class to wordpress ?? 我是否需要注册课程以使用wordpress?
I'm not expert on PHP but to use $setting
variable as global you need to declare it as such. 我不是PHP方面的专家,但是要使用$setting
变量作为全局变量,您需要这样声明它。
Like this: 像这样:
global $setting;
$setting = new myWidgetSetting();
