WordPress: How to get plugin options from other plugin page

Question

I'm writing a WordPress plugin which has a widget, and that widget displays a link on the page like e.g.:

<a href="<?php echo plugins_url('/ext_page.php', __FILE__); ?>">Link</a>

Now in the /ext_page.php page, I need to get options from the plugin itself like e.g.:

$options = get_option('my_plugin_options');

But the function get_option seems not working in that page, is there any other way to get the options?

Please kindly advise, Thanks!

Answer 1

get_option() will always work on WordPress. Make sure you've written the option name well.

You can use a default value(empty array in this case) in case the option is not found:

$options = get_option('my_plugin_options', array() );

Go to your wp_options table and check if the value for my_plugin_options exists or is set.

Answer 2

Another consideration, maybe the option is serialized in the wp_options database table? In that case, you can retrieve the value as follows:

$options = get_option('my_option', 'default text');
$option = $options['field_one'];

Option data appears in the option_value field. If it's serialized, it will look something like this:

a:1:{s:11:"field_one";s:7:"foobar";}
