W3 Total Cache – ACF /PHP Variables

    Hi, I’ve managed to get the Page Fragment Cache block running okay, but noticed that I can’t seem to run any if/else logic against a php, or acf, field variable and I was wondering if this is perhaps just because of the life-cycle of how the page fragment caching works?

    For example I currently have this on my page:-

    <!– mfunc mysecuritystring –>

    if( get_field( ‘my_acf_field’ ) ){
    echo ‘hello world’;
    }

    <!– mfunc mysecuritystring –>

    But the get_field always return null…and the echo is never printed to the screen…

    However if I just var_dump the get_field value in normal php tags it will return true

    Many thanks

    Hello @leem321

    Thank you for your question and I am happy to help!
    “Page Fragment Cache” dynamically loads the content (in real-time) on your cached pages by parsing them for specific tags you manually embed. There is no reason the if/else logic would not work as you can see in the example in our FAQ.
    Make sure everything is correctly set up.
    Thanks!

    Hi Marko, thanks for you response. Yes it seems I did have everything setup correctly from the back-end/plugin settings (Page Cache / Disk: Basic,
    Late initialization)

    I solved my particular problem by attempting to determine the current post id using the url_to_postid function inside the non-cache block e.g.

    <!– mfunc mysecuritystring –>

    $tmpW3TCURL = $_SERVER[‘REQUEST_URI’];
    $setPagePostID = url_to_postid( $tmpW3TCURL );

    if( get_field( ‘my_acf_field’, $setPagePostID ){
    }

    <!– /mfunc mysecuritystring –>

    Not sure how robust this is, but it seems to do the job from my initial testing…thanks again for the response.

    Regards
