php - How to use two isset condition in single page -


how use 2 isset() conditions in same page?

this how code looks:

    if (isset($_post["location_from"]) && !empty($_post["location_from"]))     {          .........         .........         echo json_encode($returnvalues);             }     if (isset($_post["location_to"]) && !empty($_post["location_to"]))     {             .........            .........             echo $value;     }   if (isset($_get["id"]) && !empty($_get["id"]))     {             .........            .........             echo $value_id;     }

so in above code when pass value in ajax $_post['location_from'] works perfectly, , when pass value in ajax $_get['id'] works perfectly, when pass value in ajax $_post['location_to'] function inside $_post['location_from '] working , echoing. appreciated.

if want write max 1 value (the first condition met), use elseifs instead of ifs.

if (!empty($_post['location_to'])) {     echo ...; } elseif (!empty($_post['location_from'])) {     echo ...; } elseif (!empty($_get['id'])) {     echo ...; }
