php - How to update 3 tables columns while only one column is visible to the page -


this table column display message depends on user preferred language choice in db. eg if preferred language eng eng message show ps: in database, there's 3 column storing 3 types of message of different languages

 <?php  $possiblelang = ["繁體","简体","eng"];  $testareafield = ["traditionalmessage","simplifiedmessage","engmessage"];  $treatmentname = ["vaccinename1","vaccinename2","vaccinename3"];  $treatmentnamesuffix = ["\n下一個注射期為:","\n下一个注射期为:","\nnext   injection period be:"];   $index = array_search($row['language'],$possiblelang);  ?> <td> <textarea  rows="3" cols="18" class="url" name="<?php echo   $testareafield[$index]; ?>[]" data-value="<?php echo   $row[$treatmentname[$index]] . $treatmentnamesuffix[$index]; ?>"><?php echo   $row[$testareafield[$index]]; ?>  </textarea>  </td>

this table @ edit page displays data db , updates data db. 

 if (isset($_post['submit'])){   foreach ($_post['patientid'] $index => $patientid) {     $id = mysql_real_escape_string($_post['id'][$index]);     $data1 = mysql_real_escape_string($patientid);     $data17 = mysql_real_escape_string($_post['patienthkid'][$index]);      $data2 = mysql_real_escape_string($_post['vaccineid'][$index]);     $data5 = mysql_real_escape_string($_post['vaccinename3'][$index]);     $data6 = mysql_real_escape_string($_post['totalnoofinjection'][$index]);     $data7 = mysql_real_escape_string($_post['nthinjection'][$index]);     $data8 = mysql_real_escape_string($_post['date'][$index]);     $data9 = mysql_real_escape_string($_post['nextdate'][$index]);     $data10 = mysql_real_escape_string($_post['skip'][$index]);     $data11 = mysql_real_escape_string($_post['language'][$index]);     $data12 = mysql_real_escape_string($_post['traditionalmessage'][$index]);     $data13 = mysql_real_escape_string($_post['simplifiedmessage'][$index]);     $data14 = mysql_real_escape_string($_post['engmessage'][$index]);     $data15 = mysql_real_escape_string($_post['status'][$index]);     $data16 = mysql_real_escape_string($_post['nurse'][$index]);      if ($data12 != null) {     mysql_query("update patientvaccinedetail set patientid     ='$data1',patienthkid     ='$data17',vaccineid='$data2',vaccinename3='$data5',      totalnoofinjection='$data6',nthinjection='$data7',     date='$data8',nextdate='$data9',skip='$data10',language='$data11',     traditionalmessage='$data12',status='$data15',nurse='$data16'      id=$id")   or die(mysql_error());      }     else if ($data13 != null) {    mysql_query("update patientvaccinedetail set patientid      ='$data1',patienthkid     ='$data17',vaccineid='$data2',vaccinename3='$data5',    totalnoofinjection='$data6',     nthinjection='$data7',date='$data8',nextdate='$data9',    skip='$data10',language='$data11',    simplifiedmessage='$data13',status='$data15',nurse='$data16'      id=$id")   or die(mysql_error());     }   else if ($data14 != null) {   mysql_query("update patientvaccinedetail set patientid    ='$data1',patienthkid ='$data17',vaccineid='$data2',   vaccinename3='$data5', totalnoofinjection='$data6',     nthinjection='$data7',date='$data8',nextdate='$data9',    skip='$data10',language='$data11',    engmessage='$data14',status='$data15',nurse='$data16' id=$id")    or die(mysql_error());     }      }     }

the issues whenever click save , only one column of message saved, other 2 column updated null in database. desired outcome update both 3 columns while 1 column visible page. idea. in advance

do not update columns not being targeted update. example, if traditional message selected, update column. use separate queries here.

foreach ($_post['patientid'] $index => $patientid) {     $id = mysql_real_escape_string($_post['id'][$index]);     $data1 = mysql_real_escape_string($patientid);     $data2 = mysql_real_escape_string($_post['traditionalmessage'][$index]);     $data3 = mysql_real_escape_string($_post['simplifiedmessage'][$index]);     $data4 = mysql_real_escape_string($_post['engmessage'][$index]);      if ($data2 != null && $data2 != '') {         mysql_query("update table set patientid ='$data1',           traditionalmessage='$data2' id=$id")   or die(mysql_error());     }     else if ($data3 != null && $data3 != '') {         mysql_query("update table set patientid ='$data1',           simplifiedmessage='$data3' id=$id")   or die(mysql_error());     }     else if ($data4 != null && $data4 != '') {         mysql_query("update table set patientid ='$data1',           engmessage='$data4' id=$id")   or die(mysql_error());     } }

note believe using old , deprecated php api mysql. starters, benefit lot using prepared statements.
