I guess in the meantime you figured in out already. Though I want to share my experience since I faced the same problem and it might be useful for others. In my case I just got the reference to the options wrong when creating the HTML code for the input-elements. So since WordPress suggests to … Read more
Correct way of modifying a variable using hooks If you want to modify a variable or any value using hooks, it’s best to do that using filter hooks (instead of action hooks). Although internally the implementation is almost the same for actions and filters, the convention is: With action hooks, you do something, echo output … Read more
You can set slug of a subpage to be the same as slug of parent page. For example: public function onixion_admin_menu_option() { add_menu_page(‘onixion’, ‘Onixion’, ‘manage_options’, ‘onixion-admin-menu’, array(&$this, ‘onixion_main_page’ ), ‘dashicons-chart-area’, ‘200’ ); add_submenu_page( ‘onixion-admin-menu’, ‘scripts’, ‘Scripts’, ‘manage_options’, ‘onixion-admin-menu’, // <– here we set the same slug as for parent page array(&$this, ‘onixion_scripts_page’ ) ); add_submenu_page( … Read more
As we can see from the registerFormatType function source code, only letters, numbers, “_” and “-” are allowed in the class name. if ( ! /^[_a-zA-Z]+[a-zA-Z0-9-]*$/.test( settings.className ) ) { window.console.error( ‘A class name must begin with a letter, followed by any number of hyphens, letters, or numbers.’ ); return; } So you cannot separate … Read more
There’s nothing technically wrong with this. It will work, but it’s very important to make sure the usage of the filter is consistent everywhere it’s used, otherwise you could experience issues. My suggestion would be to abstract the powers check into a separate function, and use the filter there. For example, the filter could be … Read more
Do I need to sanitize the data before putting the text back in a text box for edit. You “sanitize” data that you are receiving. Then “escape” it when outputting. Depending on your exact code (which you did not provide any examples of), you may want to do more than stripslashes() (or replace that altogether). … Read more
From your comment: Those htaccess changes don’t happen as a result of an add_action. Perhaps they should? Yes, they should. And here’s why insert_with_markers() calls switch_to_locale() which uses $GLOBALS[‘wp_locale_switcher’] (or $wp_locale_switcher) which is initialized in wp-settings.php, but only after WordPress runs the setup_theme hook. And looking at the error in question and line #1582 in … Read more
I have seen many plugins do it this way. But it definitely seems like a very tedious step to follow for the user in order to use the plugin… Is it the right method? Yes. Should I somehow, store my Consumer API key & secret details on my server? And any of my distributed plugins … Read more
I’m not 100% certain this is your problem, but… I believe your “no_items” function should return the value, not echo it. If there are no items, that would lead to a “headers already sent” when the redirect is fired. Try it like this: /** Text displayed when no customer data is available */ public function … Read more
It’s not a good idea to modify plugins if you can help it, as the plugin may be upated and you will lose your changes and need to redo them. Fortunately, that is not necessary in this case anyway, as you can the filter active plugins option instead. You will need the plugin slug for … Read more
