Question

I am new to OOP and have a class, inside this class I am trying to run

foreach($categories as $category) { 
                public function beam_channels_setting.$category->name()
                {
                    echo "<input name='beam_plugin_options[beam_channels".$category->name"]' type='text' value='{$this->options['beam_channels.$category->name']}'/>";

                        } 
        }

However I keep getting this error: unexpected T_FOREACH

I understand that this is because it is looking for a function, but I do not know how to overcome this, would I put it all within another function?

class

Class BEAM_Options {

    public $options;
    public $categorielist;

    public function __construct()
    {
        $args = array(
            'type'                     => 'post',
            'orderby'                  => 'name',
            'order'                    => 'ASC',
            'hide_empty'               => 0, //<--IMPORTANT!!
            'hierarchical'             => 1,
            'taxonomy'                 => 'category',
            'pad_counts'               => false );
        $categories = get_categories($args);
        $this->options = get_option('beam_plugin_options');
        $this->register_settings_and_fields();
    }

    public function add_menu_page()
    {
        add_options_page('Ad Management', 'Ad Management', 'administrator', __FILE__, array('BEAM_Options', 'display_options_page'));
    }

    public function display_options_page()
    {
        ?>

        }
    }


          foreach($categories as $category) { 
                public function beam_channels_setting.$category->name()
                {
                    echo "<input name='beam_plugin_options[beam_channels".$category->name"]' type='text' value='{$this->options['beam_channels.$category->name']}'/>";

                        } 
        }
}

Answer 1

public function beam_channels_setting.$category->name() {..}

will not works. If you want to declare your function, it must be outter of your loop.

public function functionName(){
     ...
}

and then use it in your loop:

foreach(...){
  $this->functionName();
}

in your class.
