Hi!

Can you explain how to use this Class? I want to set an option with name = 'demo' as value = jSON in wp_options table...

Thank you!

Hi there,

You would obviously need to require that file in your code. You could then do something like this:

$options = new My_Plugin_Options('my_option_name_in_db');
$this->options->my_setting1 = 'my_value';
$this->options->my_setting2 = 'my_second_value';
$this->options->save();

To pull the value back, you'd simply call:

$this->options->my_setting1

$this->options->my_setting1

Thank you! Now I can make new options/value and change value of those options.

I want to understand how can I do something more:

  • Delete a key (like 'my_setting1')
  • Check if a key exist or not
  • Can we make a nested jSON with this?

Many thanks! :D

My another question :D! I can set nested jSON like this:

  • $this->options->my_setting3 = array('a3'=>'A3','b3'=>'B3');

My question is how I can modify value 'A3' of 'a3' key only...

Thanks!
