Foreach loop through Gravity Forms entries

Not sure how relevant the answer is now, but it might help someone in future.

1. It would be advisable to switch $entries and $entry. It’s quite confusing that you use $entries for singular entry and $entry for an array of entries.

2. Define what output you are looking for. You are looking to get an array, but you’re rewriting your values with each loop – that’s why the last one stands- like you’re repainting a house and wondering why only the top color can be seen…

3. I’d say you want to do this to the $calendar_data array and an $outputx output:

   $calendar_data = array();
   
   $outputx = "";
   
   $entries = GFAPI::get_entries($form_id, $search_criteria, $sorting, $paging, $total_count);
   
   foreach ($entries as $entry) {
       $idx = rgar($entry, 'id');
       $calendar_data[$idx]["fname"] = rgar($entry, '13.3');
       $calendar_data[$idx]["lname"] = rgar($entry, '13.6');
       $calendar_data[$idx]["pto_start"] = rgar($entry, '1');
       $calendar_data[$idx]["pto_end"] = rgar($entry, '3');
       $calendar_data[$idx]["e_location"] = rgar($entry, '16');
       $calendar_data[$idx]["pto_approval"] = rgar($entry, '15');
   
       $supervisor_location = um_user('employee_location');
   
       if (($supervisor_location === 'Elk City, OK') && ($e_location === 'Elk City, OK' )) {
           if ($pto_start != $this->currentDate) {
               $outputx .= '<div id="' . $this->currentDate . '" class="day ' . ($cellNumber % 7 == 1 ? ' start ' : ($cellNumber % 7 == 0 ? ' end ' : ' ')) .
               ($cellContent == null ? 'mask' : '') . '">' . $cellContent . '</div>';
           } elseif ($pto_start == $this->currentDate) {
               $outputx .= '<div id="' . $this->currentDate . '" class="day has-pto ' . ($cellNumber % 7 == 1 ? ' start ' : ($cellNumber % 7 == 0 ? ' end ' : ' ')) .
               ($cellContent == null ? 'mask' : '') . '">' . $cellContent . '<div class="inner-pto-cal ' . lcfirst($pto_approval) . '">' . $fname . ' ' . $lname . '</div></div>';
           }
       }
   }
