mysql - PHP with SQL Server - 500 Internal Server Error -


i working on project written in php , connecting mysql database part of masters class project, seemed have missed in scope using mssql database in our system.

i in process of going through files , adjusting queries etc in order work our database. in couple of places hitting wall 500 internal server error. in both cases, it's queries have variables in them, ie. search terms.

two examples of functions giving me error: 

function callstores(){         $conn= databaseconnection();                 $list=  json_decode(stripslashes($_post['list']));         $storeslist="<br>";         if(count($list)==0)         {             echo "<br> no stores display x<br><br>";             //echo "calling no stores!";         }          else         {             //echo "calling stores!";              foreach($list $d){                              $sql = "select  customerstoreid, customerid, storename, address1, town                              tblcustomerstores                          customerid= $d;";                  $result = sqlsrv_query($conn,$sql, array(), array( "scrollable" => 'static' ));                  //if sql succeed                 if (sqlsrv_num_rows($result) > 0)                  {                     while($row = sqlsrv_fetch_array( $result, sqlsrv_fetch_numeric))                      {                          $storeslist .=  '<p id="">                                                 <input type="checkbox" name="stores[]"                                                           value="'. $row["0"].'"> '                                                 . $row["2"].' '. $row["3"].', '.$row["4"]                                                 .'</p>';                     }                 }                 else                 {                     $storeslist .= "0 results";                 }                }//close loop               echo $storeslist.'<br>';         }     }

and second example 

function searchcustomer(){         $conn= databaseconnection();         if(isset($_post['hint']) && ($_post['hint']!=""))         {             $hint =$_post['hint'];             $sql = "select                               customerid,                     customername1,                     customername2                             tblcustomers customername1 '".$hint."%' order customername1;";          } else {             $sql = "select                                       customerid,                             customername1,                             customername2                             tblcustomers order customername1;";         }          $result = sqlsrv_query($conn,$sql, array(), array( "scrollable" => 'static' ));  ;         //if sql succeed         if (sqlsrv_num_rows($result) > 0)          {             while($row = sqlsrv_fetch_array( $result, sqlsrv_fetch_numeric))              {                 echo                     '<input type="checkbox" name="customers[]"                              onchange="changestoreslist()"                              value="'. $row["0"].'"> '                             . $row["1"].' '                             . $row["2"]                             .'<br>';              }         }         else         {             echo "0 results";         }         sqlsrv_close( $conn);       }

am correct in assumption in both cases it's search term causing problem, , if - correct approach it?

when check console, following: post http://localhost/includes/functions.php

500 internal server error 47ms

the "post" tabs shows: action showstores list ["4441"]

any suggestions appreciated!

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
