External Popup Onclick To Open Only Once Per Session

I was able to duplicate the functional popup (coding is hell for me). The problem is that every time you click on the page. What's annoying. Is there a possibility for me as a beg

Solution 1:

yes, you can do that using cookies .

php has functions for dealing with cookies , mainly setcookie() and companions

**/ Set a Cookie /* 

    add_action( 'init', 'set_mycookie' );
    functionset_mycookie() {
    setcookie( 'cookiename', 'cookievalue', time() + 3600, COOKIEPATH, COOKIE_DOMAIN   );
    }

**/ Get a Cookie /*

    add_action( 'wp_head', 'get_mycookie' );
    functionget_mycookie() {
    $myvar= isset( $_COOKIE['cookiename'] ) ? $_COOKIE['cookiename'] : 'cookie not set';

    }

**/ Delete or Unset /* 

    add_action( 'init', 'unset_mycookie' );
    functionunset_mycookie() {
    setcookie( 'cookiename', '', time() - 3600, COOKIEPATH, COOKIE_DOMAIN );
    }

now, of course these are the most basic general examples, but you could use it with any set of conditions, ( like @Bibberty comment/question ) for example by session, by user, by day, by page, etc . whatever you want .

Sidenote - wp has dedicated functions for using cookies, mainly for auth and session management ( which wp does not do by default ). see wp_set_auth_cookie() to learn more

sidenote 2 Also, regarding your code ... embading php inside JS ( or viceversa...) is a bad practice. wp has actually a very cool and elegant function to deal with that, and if you really want to learn php/wp - you better start using it now

Solution 2:

Its done , I did a popup with a css class with a z-index, and I inserted a transparent image as a external link with _blank and onclick into body. Maybe unprofessional but functional

Solution 3:

you can do with partial javascript partial php,

1) Php Based Cookie - Session session check

2) Javascript : Cookie - LocalStorage based session check
