I'm a beginner and I have a problem with a part of the script that I found in a post. Practically when printing the checkboxes it does it outside the table. I can't bring the content of the foreach into the variable $input.
is there anyone who can help me and tell me how to change the foreach part of the checkboxes?
Thanks a lot
here is the screenshot

foreachforcheckbox_groupyou should append to$inputvariable and you use,instead of.(twice) to concatenate strings. Before and after$meta_value && in_array($option['value'], $meta_value).
