Hello there, I’m getting a non-numeric value encountered warning on the line with the + in PHP 7.4. By changing the following from:

PHP:
// Color picker
                case "color":
                    $default_color = '';
                    if ( isset($value['std']) ) {
                        if ( $smof_data[$value['id']] !=  $value['std'] )
 +                            $default_color = ' data-default-color="' .$value['std'] . '" ';
                    }
                    $output .= '<input name="' . $value['id'] . '" id="' . $value['id'] . '" class="of-color"  type="text" value="' . $smof_data[$value['id']] . '"' . $default_color .' />';
            
                break;

and add an (int) to:

PHP:
// Color picker
                case "color":
                    $default_color = '';
                    if ( isset($value['std']) ) {
                        if ( (int)$smof_data[$value['id']] !=  $value['std'] )
 +                            $default_color = ' data-default-color="' .$value['std'] . '" ';
                    }
                    $output .= '<input name="' . $value['id'] . '" id="' . $value['id'] . '" class="of-color"  type="text" value="' . $smof_data[$value['id']] . '"' . $default_color .' />';
            
                break;

The error goes away but shouldn’t I also be adding an (int) in front of $default_color too? Basing this on this link https://stackoverflow.com/questions/42044127/warning-a-non-numeric-value-encountered

hello !

(int) is a Cast function, which convert 'symbols' to an (int) value,

if the 'comparing test' fails, maybe the \left or /right value ($smof_data[$value['id']] !||||= $value['std']) are untyped or from another type.

the function gettype($value) can help you to debug.
the two operators '===' or '!==' can help you too, because they check 'values' and the 'type' too.


I have a question : about $value['std'], what is the value in ?

This is the entire page of code. Around line 38 is first mention of $value.
