using wp_footer hook in a plugin

Question

I'm using the wp_footer hook into the plugin and it doesn't work, but when I copy the code to the "functions.php" file of the active theme it does work, what is the possible problem in this situation ?

    function mixpanel_footer(){

echo '<a style="margin-left:45%;" href="https://mixpanel.com/f/partner"><img src="//cdn.mxpnl.com/site_media/images/partner/badge_white.png" alt="Mobile Analytics" /></a>';

     } 
    add_action( 'wp_footer', 'mixpanel_footer' );

Answer 1

Firstly, remove the margin-left CSS property from your html and then try if it works. May be your html is being hidden behind any other html.

Or better try this first -

Remove the current code from your function and just write any non html thing. Then put a die() or exit() and see if it's being rendered properly. Then you can do further debugging.

Answer 2

Try adding priority to hook as following:

function mixpanel_footer(){

echo '<a style="margin-left:45%;" href="https://mixpanel.com/f/partner"><img src="//cdn.mxpnl.com/site_media/images/partner/badge_white.png" alt="Mobile Analytics" /></a>';

 } 
add_action( 'wp_footer', 'mixpanel_footer', 5 );

Can you please use this code? I think it will work properly.

function your_function(){
    do_action( 'your_action' );
}
add_action( 'wp_footer', 'your_function' );
