I'm trying to store browser's geoposition obtained with javascript and posted via $.ajax into mysql table with php. I receive the posted data and converted in a recursive array so I can get only the latitude and longitude data but I'm getting two warnings(I will comment on code):
1->Warning: mysqli_real_escape_string() expects parameter 2 to be string, object given in.
2->Warning: mysqli_error() expects exactly 1 parameter, 0 given in
Here is my code:
geolocation and send data:
if (window.navigator.geolocation) {
var failure, success;
success = function (position) {
console.log(position);
var stringData = JSON.stringify(position, null);
$.ajax({
type: "POST",
url: "GL_.php",
data: {
data: stringData
}
});
};
failure = function (message) {
alert('Cannot retrieve location!');
};
navigator.geolocation.getCurrentPosition(success, failure, {
maximumAge: Infinity,
timeout: 5000
});
}

The variables $lat and $lng are populated each one with the corresponding value but as I've mentioned previously the error came up. Can anyone explain what's wrong here?
For the first error your problem is you are calling your GetSQLValueString method wrong, you have it defined as
GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
but are calling it with these arguments
GetSQLValueString($cs_connection, $lat, "text"),
GetSQLValueString($cs_connection, $lng, "text")
so $theValue gets set to an object (the mysqli link)
As for the mysqli_error error you are not passing it the required argument
http://php.net/manual/en/mysqli.error.php
Procedural style
string mysqli_error ( mysqli $link )
you have:
die(mysqli_error())
it should be
die(mysqli_error($cs_connection))
Catch like this:
if($cs_connection){
$theValue = mysqli_real_escape_string($cs_connection, $theValue);
} else {
// No DB Connection, so no way reason to escape
}

XSS code in database
datable
While displaying data from database, use htmlspecialchars() function.
I am having trouble making an PHP API to get data from MYSQL and parse JSON. I have a demo app (hiApp) and comes with some JSON files inside a folder.
The demo JSON file is like this:
{ "err_code": 0, "err_msg": "success", "data": [{"nickname":"Joao","location":"I.13"},{"nickname":"Victor","location":"2811"}]}
This what my contacts.php is returning:
[{"nickname":"Joao","location":"I.13"},{"nickname":"Victor","location":"2811"}]
My contacts.php api looks like this:
…
…
$result = mysql_query("select * from sellers", $db);
$json_response = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
$row_array['nickname'] = $row['first_name'];
$row_array['location'] = $row['territory'];
array_push($json_response,$row_array);
}
echo json_encode($json_response);
?>
The js file to parse JSON, looks like this:
define(['utils/appFunc',
'i18n!nls/lang',
'components/networkStatus'],function(appFunc,i18n,networkStatus) {
//var apiServerHost = window.location.href;
var xhr = {
search: function(code, array){
for (var i=0;i< array.length; i++){
if (array[i].code === code) {
return array[i];
}
}
return false;
},
getRequestURL: function(options){
//var host = apiServerHost || window.location.host;
//var port = options.port || window.location.port;
var query = options.query || {};
var func = options.func || '';
var apiServer = 'api/' + func + '.php' +
(appFunc.isEmpty(query) ? '' : '?');
var name;
for (name in query) {
apiServer += name + '=' + query[name] + '&';
}
return apiServer.replace(/&$/gi, '');
},
simpleCall: function(options,callback){
options = options || {};
options.data = options.data ? options.data : '';
//If you access your server api ,please user `post` method.
//options.method = options.method || 'GET';
options.method = options.method || 'POST';
if(appFunc.isPhonegap()){
//Check network connection
var network = networkStatus.checkConnection();
if(network === 'NoNetwork'){
hiApp.alert(i18n.error.no_network,function(){
hiApp.hideIndicator();
hiApp.hidePreloader();
});
return false;
}
}
$$.ajax({
url: xhr.getRequestURL(options) ,
method: options.method,
data: options.data,
success:function(data){
data = data ? JSON.parse(data) : '';
var codes = [
{code:10000, message:'Your session is invalid, please login again',path:'/'},
{code:10001, message:'Unknown error,please login again',path:'tpl/login.html'},
{code:20001, message:'User name or password does not match',path:'/'}
];
var codeLevel = xhr.search(data.err_code,codes);
if(!codeLevel){
(typeof(callback) === 'function') ? callback(data) : '';
}else{
hiApp.alert(codeLevel.message,function(){
if(codeLevel.path !== '/')
mainView.loadPage(codeLevel.path);
hiApp.hideIndicator();
hiApp.hidePreloader();
});
}
}
});
}
};
return xhr;
});
I know the error is in the way contacts.php is displaying the JSON results or I need to change something in the js file.
Thanks for the help.
Based on your comments above I've tried to rewrite a solution keeping the same structure, but removing the unnecessary things; this is what the code may look like. Note that there are no references to err_code and err_msg peoperties, and the callback is called directly on data variable.
define(['utils/appFunc',
'i18n!nls/lang',
'components/networkStatus'],function(appFunc,i18n,networkStatus) {
//var apiServerHost = window.location.href;
var xhr = {
getRequestURL: function(options){
//var host = apiServerHost || window.location.host;
//var port = options.port || window.location.port;
var query = options.query || {};
var func = options.func || '';
var apiServer = 'api/' + func + '.php' +
(appFunc.isEmpty(query) ? '' : '?');
var name;
for (name in query) {
apiServer += name + '=' + query[name] + '&';
}
return apiServer.replace(/&$/gi, '');
},
simpleCall: function(options,callback){
options = options || {};
options.data = options.data ? options.data : '';
//If you access your server api ,please user `post` method.
//options.method = options.method || 'GET';
options.method = options.method || 'POST';
if(appFunc.isPhonegap()){
//Check network connection
var network = networkStatus.checkConnection();
if(network === 'NoNetwork'){
hiApp.alert(i18n.error.no_network,function(){
hiApp.hideIndicator();
hiApp.hidePreloader();
});
return false;
}
}
$$.ajax({
url: xhr.getRequestURL(options) ,
method: options.method,
data: options.data,
success:function(data){
data = data.length > 0 ? JSON.parse(data) : [];
if (typeof(callback) === 'function' && data !== undefined)
callback(data);
}
});
}
};
return xhr;
});
Then you may call it this way, using directly response var, which now contains the parsed data array:
loadContacts: function() {
if(VM.module('contactView').beforeLoadContacts()) {
xhr.simpleCall({
query: { callback: '?' },
func: 'contacts'
}, function (response) {
if (response !== undefined) {
VM.module('contactView').render({
contacts: response
});
}
});
}
}
Also, you would have to add
header('Content-Type: application/json');
before your PHP echo line in order to be able to parse it in JS.
Ok, many thanks Andrea, looks like there is something else that I'm missing because the results from the contacts.php and the initial contacts.php file is the same in my browser:
[{"nickname":"Joao","location":"I.13"},{"nickname":"Victor","location":"2811"}]
It works just fine if I use the initial contacts.php that only has pure json data like above, but if I switch to my api it stops working.
Also it stops working if I use this in the initial contacts.php:
<?php
$myString = '[{"nickname":"Joao","location":"I.13"},{"nickname":"Victor","location":"2811"}]';
echo $myString;
?>
I'll keep looking, but thanks to you I'm one step ahead.

How to parse JSON data with jQuery / JavaScript?
(11 answers)
Closed 8 years ago.
I have the following problem,
I'm sending a json_encoded data array from PHP to javascript. The actual JSON I'm receiving from PHP is shown below,
{
"route": "1(M)A",
"startSignal": "AN1",
"startX": 100,
"startY": 320,
"direction": "down",
"endSignal": "AN3",
"endX": 1100,
"endY": 320,
"1AT": {
"length": "100",
"xStart": 100,
"yStart": 320,
"xFinish": 133.33333333333,
"yFinish": 320
},
"1BT": {
"length": "100",
"xStart": 133.33333333333,
"yStart": 320,
"xFinish": 166.66666666667,
"yFinish": 320
},
"1CT": {
"length": "100",
"xStart": 166.66666666667,
"yStart": 320,
"xFinish": 200,
"yFinish": 320
},
"1DT": {
"length": "100",
"xStart": 200,
"yStart": 320,
"xFinish": 233.33333333333,
"yFinish": 320
}
}
In my .JS file, I'm getting the "echo json_encode($dataArray)" as follows,
$.ajax({
url: "visualiser/visualiser_RouteList.php",
data: "JSON",
async: false,
success: function(data){
console.log(data);
}
});
The problem is that for some reason ajax reads the json in the following manner..(every character in JSON is stored as an array element.. so I can't retrieve a particular value of an associated name for example, getting "1(M)A" String value from associated name "route"..
data[0] = "{"
data[1] = " \" "
data[2] = "r"
data[3] = "o"
where am I going wrong?
============================================================================
further edit after receiving the comments,
Thanks everyone, I did change the data to 'dataType = "json"' but it still doesn't work..I really wanted to see [object, object....] when I do 'console.log(data) but nothing is printing out so there must be something wrong with my $array in the PHP source, not sure if anyone's willing do have look but I'm posting my php source here..(Sorry for being a total noob at PHP..I can't seem to be doing anything but pulling my hair out)

You need the dataType rather the data.
$.ajax({
url: "visualiser/visualiser_RouteList.php",
dataType: "JSON",
async: false,
success: function(data){
console.log(data);
}
});
Your response is not being recognised as JSON, so it is not being deserialised. Presently it is being received as a string, hence why accessing by index is giving you the character of the string at that position.
You either need to set the headers in the response in PHP to JSON, or force the jQuery to deserialise it for you using dataType: 'json':
$.ajax({
url: "visualiser/visualiser_RouteList.php",
dataType: 'json',
async: false,
success: function(data){
console.log(data);
}
});
Also, when the response is correctly deserialised to an object, you cannot access it using indexes. You need to use the keys, like this:
data.route; // = '1(M)A'
$.ajax({
url: "Url",
dataType: 'JSON',//'datatype the ajax function expects',
type: "post or get",//action type
data:data to be posted,
async: false,
success: function(data){
console.log(data);
}
});,
refer this for more http://api.jquery.com/jquery.ajax/
As explained in this question & answer thread here, instead of data use dataType and instead of uppercase JSON try using lowercase json:
$.ajax({
url: "visualiser/visualiser_RouteList.php",
dataType: "json",
async: false,
success: function(data){
console.log(data);
}
});

Comment out the line:
echo 'length of the tables name: '.$resultsListTables.' ';
Also, when outputting JSON for an AJAX call, it's important to set the Content-type header using:
header('Content-type: application/json; charset=utf-8',true);
This php code doesn't seem to have syntax error. the problem probably lies on the included php's: "connect.php" and "JSON.php". could you please post them too so we can find the error.
Link this into the beginning of your PHP-file:
header("Content-Type: text/javascript; charset=utf-8");
I am a beginner using ajax and am trying to change the status of reading a book by clicking an image.
I had the code working but without ajax. Now I have no php error but not a change in mysql.
The code:
<script type="text/javascript">
function sendState(state_id){
var hd_haveread = $("#hd_haveread").val();
var hd_toread = $("#hd_toread").val();
var hd_reading = $("#hd_reading").val();
var val = 0;
var baseurl = "img/";
switch(state_id){
case 1:
if (hd_haveread == "0"){
document.getElementById('hd_haveread').value = "1";
document.getElementById('hd_toread').value = "0";
document.getElementById('hd_reading').value = "0";
val = 1;
}
else{
document.getElementById('hd_haveread').value = "0";
val = 0;
}
break;
case 3:
if (hd_toread == "0"){
document.getElementById('hd_toread').value = "1";
document.getElementById('hd_haveread').value = "0";
document.getElementById('hd_reading').value = "0";
val = 1;
}
else{
document.getElementById('hd_toread').value = "0";
val = 0;
}
break;
case 2:
if (hd_reading == "0"){
document.getElementById('hd_reading').value = "1";
document.getElementById('hd_haveread').value = "0";
document.getElementById('hd_toread').value = "0";
val = 1;
}
else{
document.getElementById('hd_reading').value = "0";
val = 0;
}
break;
}
var parameters = {
"book" : <?php echo $id_book; ?>,
"state" : state_id,
"val" : val
};
$.ajax({
cache: false,
data: parameters,
url: 'change_state_ajax.php',
type: 'post',
dataType: "html",
beforeSend: function (){
},
success: function (response){
switch(state_id){
case 1:
if (hd_haveread == "0"){
$("#img_haveread1").css("display","none");
$("#img_haveread2").css("display","inline-block");

And the change_state_ajax.php code:
<?php

$result=changeState($lib_id, $state, $val);
echo $result;
}
function changeState($lib_id, $state, $val){
session_start();
$usu_id = $_SESSION['USSER']['id'];
$mark = 0;
$pos = 0;
$query = $pdo->prepare('SELECT uliusu_id, ulilib_id, uliedl_id FROM '.TABLE_USSERS_BOOKS.' WHERE ulilib_id = :fil_lib_id AND uliusu_id = :fil_usu_id');

}
}
if($state == 1){
$result = 0;
}else{
$result = 1;
}
return $result;
}
?>
Can anyone help me solve this?
Thanks.
You are not checking for the proper variables. Your JavaScript passes a var called estado but you check in PHP for a var called state.
And because you require all three variables to be set your condition fails.
Also like Hank said in his comment your jQuery.Ajax call uses POST (type: 'post',) but then in your PHP script you check GET variables which of course are not set.
Either change you jQuery call type to GET or change the checking in your PHP script to POST
if(isset($_POST['book']) && isset($_POST['state']) && isset($_POST['val'])){
include 'connection.php';
include('php_lib/config.ini.php');
include_once('php_lib/login.lib.php');
$lib_id = $_POST['book'];
$state = $_POST['state'];
$val = $_POST['val'];
$result=changeState($lib_id, $state, $val);
echo $result;
}
Things I noticed:
1) First you are POSTing but in PHP, you are using $_GET.
2) you are passing "book", "estado", "val" but are trying to get "book", "state", "val", so it never enters into if condition
