Courses Plus Student 11,182 Pointswordpress plugin using class functions problem
So this is my first time making a plugin using basic OOP principles. My plugin basically looks something like this at the moment:
/*
plugin info
*/
class plugin_name {
public function __construct() {
//this is repeated for a whole mess of other functions and I'm not sure what hooks to put them on (they are made up of api calls and basically functions with markup in them)
add_action('wp_enqueue_scripts', array($this, 'scripts')
}
public function mark_up_function1() {
..........................
..........................
}
}
$mm_stock_info = new mm_stock_info();
Then on a template page I call the markup functions like so
$mm_stock_info->mark_up_function();
when I try to load the page that is utilizing this plugin the most I get a mostly blank screen (but my css and js is loading onto the page). Does anyone have any suggestions to what my problem may be?

Courses Plus Student 11,182 PointsThis worked...
/*
plugin info
*/
class plugin_name {
public function __construct() {
//this is repeated for a whole mess of other functions and I'm not sure what hooks to put them on (they are made up of api calls and basically functions with markup in them)
$this->register_callbacks()
}
protected function register_callbacks() {
add_action('mark_up_function1', array($this, 'mark_up_function1'));
}
public function mark_up_function1() {
..........................
..........................
}
}
$mm_stock_info = new mm_stock_info();
Then in the theme something call the function with the hook you called in the plugin
do_action('mark_up_function1');

Courses Plus Student 11,182 PointsThat was a typo on my part (was trying to write up a quick example) but in the actual code the function is the correct name.

Courses Plus Student 11,182 PointsWhat hooks do you recommend I use for these functions that make an API call and present it in HTML form?
