php - Ajax request returns POST <<url>> 500 (Internal Server Error) -


i've been doing module website using wamp server , works, when upladed website server returns error 500.

error 500 1

error 500 2

when main page index.php loads (using javascript .ready function) send ajax request 'obtenermunicipio.php'.

<script type="text/javascript">     $( document ).ready(function() {         $.ajax({           type: 'post',           url: '../obtenermunicipio.php',           data : {'valor':'paz'},           datatype: 'json',           success: function(data) {             if(data.length <= 0) {               return;             }             for(var i=0; < data.length; i++) {                 var opcion = document.createelement('option');                 opcion.innerhtml+=data[i];                 document.getelementbyid('unidadmedica').appendchild(opcion);             }           },           error: function(e) {             console.log(e.message);           }         });      }); </script>

the page 'obtenermunicipio.php' receive value 'valor' , made mysql query obtain array data it's return.

<?php     include($_server['document_root'].'/noticias/conexion.php');     header('content-type: text/html; charset=iso-8859-15');     header("application/json");     $conexion=conectar();     $municipio = utf8_decode($_post['valor']);     if($municipio != "loret")         $sql = "select distinct unidadmedica `unidadesmedicas` municipio '%".$municipio."%' , localidad not '%loret%'";     else         $sql = "select distinct unidadmedica `unidadesmedicas` localidad '%".$municipio."%'";     $rs = mysql_query($sql) or die(mysql_error($conexion));      $fila = mysql_fetch_all($rs);     print json_encode($fila); ?>

any ideas of how solve it? works fine on wamp.

i'm putting inside reply instead of comment because feel getting hard keep track of since there multiple things say.

error 500 means there's wrong php script not handled correctly web server. it's undeclared (or deprecated) function or issue paths or extensions.

the first step follow in order investigate issue either finding error_log file on web server, or pasting these 2 lines @ top of php script:

<?php error_reporting(-1); // highest error reporting level ini_set("display_errors", true); // print errors directly output /* rest here */

that said, there 1 more issue code! aware it's vulnerable against sql injection attacks since you're building query string directly , else might have query totally different.

to solve that, should either use pdo , mysqli extensions' prepared statements or pass variables you're going use in query string through mysql_real_escape_string().

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
