Warning: sizeof(): Parameter must be an array or an object that implements Countable on event maker

Question

I have an event maker on Wordpress. I\'m having this error message, maybe is because I updated to PHP 7.2:

Warning: sizeof(): Parameter must be an array or an ob         


        

Answer 1

I understand specific you want. But you can resolve the following:

Update plugin new version. If plugin not support then you can fix code:

if( is_array($eventos[$day]) && sizeof($eventos[$day])>0) echo "</a>"; 

if(is_array($eventos[$day]) && sizeof($eventos[$day])>0) echo "<a href='#openModal$day' style='text-decoration:none;'>"

Or, replace by method count()

Answer 2

In PHP 7.2 sizeof Parameter must be an array or an object

Line 413:

if(is_array($eventos[$day]) && sizeof($eventos[$day]) > 0) echo "</a>";

Line 390:

if(is_array($eventos[$day]) && sizeof($eventos[$day])>0) echo "<a href='#openModal$day' style='text-decoration:none;'>";
