ANd the code line is this:

// Min Height
if ( $min_height ) {
    // Sanitize
    $min_height = esc_html( $min_height );
    if ( ! preg_match('/[A-z]/', $min_height ) && strpos( $min_height, '%' ) === false ) {
        $min_height = $min_height .'px;';
    }
    // Add inline style
    if ( $min_height ) {

Welp, where do you define `$min_height`? – j08691 Aug 11 '20 at 14:57
Simply, use `if(isset($min_height))` instead of `if($min_height)`. Older versions of PHP allowed that type of syntax, but newer versions do not. – aynber Aug 11 '20 at 14:58

For that opening if-statement condition, can you try using `if (isset($min_height))` instead of `if ($min_height)`? In PHP, checking the value of a variable that does not exist can produce errors like this. If you are trying to make sure the value is positive, then check isset first and then check that the value is positive using `intval()`. If you also need to make sure the value is a number, you can check the type using `gettype()`. – Brandon McConnell Aug 11 '20 at 15:06
Also, you're better off using `!empty($min_height)` than `isset($min_height)` because it ensures the value itself is not `=== false`, so you can rest assured there’s a truthy value contained. – Brandon McConnell Aug 11 '20 at 15:09
