I am having an issue ordering into a table primary id values which auto-increment from phpmyadmin and adding them into a table from recent to latest (greatest to lowest) can i get some help? I am using json to get php to javascript. This code only shows the table from latest to recent.
$app->get('/proyects/all', function () use($servername, $dbname, $dbuser, $dbpassword)
{
$response = array();
try
{
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $dbuser, $dbpassword);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $conn->prepare("SELECT * FROM proyectos");
if ($stmt->execute()) {
$result = $stmt->fetchAll();
}
$conn = null;
if(!empty($result))
{
$response['proyects'] = array();
foreach ($result as $key => $value)
{
$response['proyects'][$key] = $value;
}
$response['success'] = true;
echo json_encode($response);
return;
}
else
{
$response['success'] = false;
$response['message'] = "Proyects not found";
echo json_encode($response);
return;
}
}
catch(PDOException $e)
{
$response['success'] = false;
$response['message'] = $e->getMessage();
echo json_encode($response);
return;
}
});
<script type="text/javascript">
$(document).ready(function()
{
$.ajax(
{
url: path+'/proyects/all',
type: 'get',
dataType: "json",
success: function(json)
{
console.log(json);
if (json.success)
{
$.each(json.proyects, function( index, value ) {
$('#proyecs').append('<tr><td>'+value.idproyect+'</td><td>'+value.pdescription+'</td><td>'+value.presponsible+'</td><td>'+value.pdateini+'</td><td>'+value.pdatefin+'</td><td>'+value.pstatus+'%</td><td><button type="button" class="btn btn-default">Details</button></td></tr>');
});
}
else
{
Materialize.toast(json.message, 5000, 'red accent-4');
}
},
error : function(e, settings, exception)
{
Materialize.toast("Oops! an error has ocurred", 5000, 'red accent-4');
}
});
});
</script>
#sesonrario #rex sorry forgot the code
Could
$stmt = $conn->prepare("SELECT * FROM proyectos order by id");
solve your problem?

Does anyone have any idea why my AJAX function is returning each character individually. E.g.
testNew.html:150 i
testNew.html:150 t
testNew.html:150 e
testNew.html:150 m
It should be returning full words on a chart. But its printing individual letters on the console and is printing undefined on the chart.

I want to send a query result from one php file to my javascript, I've used an AJAX which seems to work as it is getting data from my BaseClass.php. However when using JSON_encode, it is not outputting anything at all. So I can't work out how to send a query result from one php file(MySQLDao.php) to my BaseClass.php so I am then able to send it to my Javascript file.
My Code:
BaseClass.php:
<?php
error_reporting(E_ALL); ini_set('display_errors', 1);
require("Conn.php");
require("MySQLDao.php");
//$param=$_REQUEST['action'];
//echo json_encode($_GET);
//echo var_dump(json_encode($_GET));
$handle = fopen("php://input", "rb");
$param = $_REQUEST['action'];
while (!feof($handle)) {
$param .= fread($handle, 8192);
}
fclose($handle);
if (empty($param))
{
$returnValue["status"] = false;
$returnValue["title"] = "Error";
$returnValue["message"] = "No Data Recieved paige" .$param ."...";
echo json_encode($returnValue);
return;
}
else
{
$dao = new MySQLDao();
if ($dao->openConnection() == false)
{
$returnValue["status"] = false;
$returnValue["title"] = "Error";
$returnValue["message"] = "Connection Could Not Be Established Between Server And Database";
ob_clean();
echo json_encode($returnValue);
}
else
{
//Decodes data, dont change
$body = json_decode($param, true);
$recieved = $body["data"];
//Gets the result of a query
$result = $dao->getResults($recieved);
}
$dao->closeConnection();
//Return the result of the query
ob_clean();
echo json_encode("param" .$param);
echo json_encode("body" .$body);
echo json_encode("recieved" .$recieved);
echo json_encode("result" .$result);
exit();
}
?>
output for the above echo statements:
"paramgetResults""body""recieved""result"

Any help is appreciated thanks!
I'm not sure why my db isn't connecting. I'm basically trying to produce a website in javascript, and I'm using an AJAX to call a method in a php file. This method is a query so I can get results of this query into some of my js components. Can anyone help please? I've been stuck for ages! Any help is appreciated.
Part of my javascript file:
function callPHP() {
$.ajax ({
type: "GET",
datatype: "application/json",
url: "BaseClass.php",
data: { action : 'getResults()' },
//error: function(err){console.log(err)},
success: function(output) {
console.log(output);

//error, function(err){console.log(err)}
});

i am building a chat website, now i working on ONLINE USER.
I use AJAX to refresh but i meet some problems with Append.();.
When refreshing section the same data appear again and again...That is the PHP file.
<?php
public function online(){
$database = new DB();
$db = $database->database();
$array = array();
$ref = $_SESSION['oc_users_ref'];
$time_out = time()-5;
$time = time();
$query = $db->query("SELECT * FROM oc_users WHERE users_online = 0");
$updateOnline = $db->query("UPDATE oc_users SET users_online = 1 WHERE users_lastcome < '$time_out'");
$q = $db->query("SELECT * FROM oc_users WHERE users_ref <> '$ref' AND users_online = 0 ORDER BY users_lastcome DESC");
while($data = $q->fetch()) {
if($data['users_online'] == 1){
$class = "opacity30";
}else{
$class = '';
}
$array[] = $data;
}
print json_encode($array);
} ?>
Now the Javascript
function getOnline(){
$.ajax({
url: "conf/users.php?act=online",
dataType: "text",
success: function(data) {
var json = $.parseJSON(data);
for (var i=0;i<json.length;++i)
{
$('#printOnline').append('<li><a href="javascript:void(0);" onclick=javascript:chatWith("'+json[i].users_nickname+'")><i></i>'+json[i].users_nickname+'</a></li>');
}
}
});
}
setInterval('getOnline()',10000);
And the result*
User001
User001
User001
User001
User001
User001
User001
User001
Please help me...Great Thanks
Reset the user list before updating:
function getOnline(){
$.ajax({
url: "conf/users.php?act=online",
dataType: "text",
success: function(data) {
$('#printOnline').html("");
var json = $.parseJSON(data);
for (var i=0;i<json.length;++i)
{
$('#printOnline').append('<li><a href="javascript:void(0);" onclick=javascript:chatWith("'+json[i].users_nickname+'")><i></i>'+json[i].users_nickname+'</a></li>');
}
}
});
}
setInterval('getOnline()',10000);
I created an android application using Phonegap. I made an account in 000webhost and I've added my PHP files on the server. In the phpMyAdmin, I've created my database.
Right, now I tried to connect my project with the online database and insert or check some data in it.
PROBLEM:
When I run the application in my mobile phone i get this alert from the success: ... part of code in ajax :
There is no such username.
(my PHP had in comments all the echo, except the: echo json_encode)
When I added this line (var_dump($_POST);) right after i am getting the $usernamefrom ajax in the PHP and run my app, I saw this alert: array(1){ [\"username\"]=> string(2) \"hi"\" }
When I added these lines: if (empty($username)) { echo '...' } , after I run my app, I saw that in the alert inside the error: ... part of the ajax, it is printed the echo that is inside this if. So, the $username is empty for sure.
This is my JavaScript file: (I get correctly for sure all the values from html so Focus on the two Ajax parts of code)

This is my PHP file in which I check if the username already exists (Username = Primary Key):
<?php
header('Content-type: application/json');
header('Access-Control-Allow-Origin: *');
//require_once('../database_config.php');
$server = "my***.000webhost.com";
$database = "a1****37_guideme";
$username = "a1****37_guideme";
$password = "*****";
$con = mysql_connect($server, $username, $password);
// if($con) { //echo "Connected to database!"; }
// else { //echo "Could not connect!"; }
mysql_select_db($database, $con);
$topost = file_get_contents('php://input');
$thedata = json_decode($topost, true);
$username = $thedata['username'];
//var_dump($_POST);
//if (empty($username)) {
// echo 'The username is either 0, empty, or not set at all';
//}
$sql = "SELECT COUNT(*) as Count FROM `user` WHERE `username`='$username'";
$result= mysql_query($sql, $con);
$rows = mysql_fetch_array($result);
$count = $rows['Count'];
if (!$result) {
die('Error: ' . mysql_error());
//$response_array['status'] = 'error';
//echo json_encode($response_array);
}
else {
if ($count == 0) {
echo json_encode(array('status' => 'success','message'=> 'There is no such username'));
//$response_array['status'] = 'success';
//echo json_encode($response_array);
}
else
{
echo json_encode(array('status' => 'error','message'=> 'The username already exists'));
//$response_array['status'] = 'error';
//echo json_encode($response_array);
}
}
mysql_close($con);
?>
And this is the PHP file in which I tried to insert the new entry in my database ( my credentials are for sure correct):
<?php
header('Content-type: application/json');
header('Access-Control-Allow-Origin: *');
//require_once('database_config.php');
$server = "mys****.000webhost.com";
$database = "a***37_guideme";
$username = "a***37_guideme";
$password = "******";
$con = mysql_connect($server, $username, $password);
// if($con) { //echo "Connected to database!"; }
// else { //echo "Could not connect!"; }
mysql_select_db($database, $con);
$topost = file_get_contents('php://input');
$thedata = json_decode($topost, true);
$username = $thedata['username'];
$password = $thedata['password'];
$email = $thedata['email'];
$gender = $thedata['gender'];
$age = $thedata['age'];
$about_you = $thedata['about_you'];
$sql = "INSERT INTO user (username, password, email, gender, age, about_you) ";
$sql .= "VALUES ('$username', '$password', '$email', '$gender', '$age', '$about_you')";
if (!mysql_query($sql, $con)) {
die('Error: ' . mysql_error());
// $response_array['status'] = 'error';
// echo json_encode($response_array);
}
else {
echo json_encode(array('status' => 'success','message'=> 'No problem'));
// $response_array['status'] = 'success';
// echo json_encode($response_array);
}
mysql_close($con);
?>
My problem solved by changing the way I get the data in my PHP to -> $user = $_POST['username']; instead of the way with Json (json_decode e.t.c.).
