Warning: A non-numeric value encountered in /templates/section-home.php on Line 34

Question

I have changed my php version from 5.6 to 7.2.

Warning: A non-numeric value encountered in /templates/section-home.php on Line 34

This is the line

 for ($j = 1; $j <= 10; $j++) { if ( px_opt('home-gallery-'.$j) ) { $slideCount+=1;  $slideNumber=$j;} }

In this code

    <?php
            $slideCount = "";
            $slideNumber= "";
            if ( px_opt('home-type-switch') == 'home-slider' ) {
              for ($j = 1; $j <= 10; $j++) { if ( px_opt('home-gallery-'.$j) ) { $slideCount+=1;  $slideNumber=$j;} }
                if ( $slideCount > 1 ) { ?>

What do I have to change? Thank you

For future reference, it is always usful to identify the LINE with the error. Specially if its line 34 and you only show us 8 lines of code — RiggsFolly, Nov 12 '18 at 14:07

try to initialize your $slideCount and $slideNumber variables as 0 instead of ""
