I have the following code in one of api files(DispatchJob_Public) and i need ajax here to call the other file(selectDriverForJobResult) after 2 minutes. I can do that in php with sleep(), but that will keep the server busy. Ajax call is at the end of the php code. Can i embed js in api code? Or is there any alternate to do what i am trying to do.
Moreover i have got response from the first file(DispatchJob_Public), but no response from the second file(selectDriverForJobResult) when i called the endpoint in postman. Because the call wasn't made. If the second file was called, it should have return some response. The strange thing is that i get response from second file when i run it in browser. I think that is because the browser supports the javascript but the call made from android to the end point doesn't support that.
Please can i get any solution for this?

I have a PHP API but when I send data to it using a post or get request the API receives half data, I don't know what the issue is. this same API works on the localhost but gives error on the Public server.

The problem is $_GET["$req_status_db"]
It should be $_GET["req_status_db"]
You will have to remove $ from all the $_GET keys.
Also, you do not have req_status_db as query param in the URL you have shared.
I send 2 variables by url:
var http = false;
http = new XMLHttpRequest();
function carrega(){
var nome = document.getElementById('CodigoUtente').value;
var nomes = document.getElementById('Nome').value;
var url_="conexao4?CodigoUtente="+nome+"&Nome="+nomes;
http.open("GET",url_,true);
http.onreadystatechange=function(){
if(http.readyState==4){
var retorno = JSON.parse(http.responseText);
document.getElementById('CodigoUtente').value = retorno.CodigoUtente;
document.getElementById('Nome').value = retorno.Nome;
document.getElementById('DataNasc').value = retorno.DataNasc;
document.getElementById('Sexo').value = retorno.Sexo;
document.getElementById('Estadocivil').value = retorno.Estadocivil;
document.getElementById('Nacionalidade').value = retorno.Nacionalidade;
document.getElementById('Responsavel').value = retorno.Responsavel;
document.getElementById('Parentesco').value = retorno.Parentesco;
document.getElementById('Contato').value = retorno.Contato;
}
}
http.send(null);
}
in the connection page4 I have the php that receives the variables:
$CodigoUtente = $_GET['CodigoUtente'];
$Nome = $_GET['Nome'];
if((isset($CodigoUtente)) && (isset($Nome))){
$query= "SELECT CodigoUtente, Nome, DataNasc, Sexo, Estadocivil, Nacionalidade, Responsavel, Parentesco, Contato FROM centrodb.PsicUtentes WHERE (CodigoUtente = '$CodigoUtente') OR (Nome LIKE '%$Nome%')";
$resultados = $conn->query($query);
$json = array();
while ($rowResultados = $resultados->fetch_assoc()) {
$dados = array(
'CodigoUtente' => $rowResultados['CodigoUtente'],
'Nome' => $rowResultados['Nome'],
'DataNasc' => $rowResultados['DataNasc'],
'Sexo' => $rowResultados['Sexo'],
'Estadocivil' => $rowResultados['Estadocivil'],

'Parentesco' => $rowResultados['Parentesco'],
'Contato' => $rowResultados['Contato']
);
$json = $dados;
}
echo json_encode($json);
}
The problem is that they only work if you fill in the two inputs and intended that they return the data from the database only when filling one of them.
Curious_Mind was saying this way?
$where_caluse = array();
if(isset($_GET['CodigoUtente'])){
$where_caluse[] = "CodigoUtente = '".$_GET['CodigoUtente']."'";
}
if(isset($_GET['Nome'])){
$where_caluse[] = "Nome = '".$_GET['Nome']."'";
}
$where = array_filter($where_caluse);
$query = "SELECT CodigoUtente, Nome, DataNasc, Sexo, Estadocivil, Nacionalidade, Responsavel, Parentesco, Contato FROM centrodb.PsicUtentes";
$resultados = $conn->query($query);
if(!empty($where)){
$final_where = count($where) > 1 ? implode(' OR ', $where) : end($where);
$query = "$query WHERE ". $final_where;
$json = array();
while ($rowResultados = $resultados->fetch_assoc()) {

I tried to apply the form it said, but it is not working, it gives 500 error when I send the values of the variables.
Can you help fix the problem? I have a form to be populated with these values
$where = " where ";
$CodigoUtente = 'a';
$Nome = '';
if($CodigoUtente != '' && $Nome != '')
{
$where .= "CodigoUtente = '$CodigoUtente' OR Nome = '$Nome';";
}else if ($CodigoUtente != ''){
$where .= "CodigoUtente = '$CodigoUtente';";
}else{
$where .= " Nome = '$Nome';";
}
$query = "SELECT CodigoUtente, Nome, DataNasc, Sexo, Estadocivil, Nacionalidade, Responsavel, Parentesco, Contato FROM centrodb.PsicUtentes".$where;
echo $query;
You can try like this way before making you sql query. This will help you to handle WHERE with OR condition, without OR condition and without any condition at all.
$where = array();
$_GET['CodigoUtente'] = 'Sany';
$_GET['Nome'] = 'Bruno';
if(isset($_GET['CodigoUtente'])){
$where[] = "CodigoUtente = '".$_GET['CodigoUtente']."'";
}
if(isset($_GET['Nome'])){
$where[] = "Nome = '".$_GET['Nome']."'";
}
$sql = "SELECT CodigoUtente, Nome, DataNasc, Sexo, Estadocivil, Nacionalidade, Responsavel, Parentesco, Contato FROM centrodb.PsicUtentes";
if(!empty($where)){
$final_where = count($where) > 1 ? implode(' OR ', $where) : end($where);
$sql = "$sql WHERE ". $final_where;
}
echo $sql;

Hi I'm trying to call a php function when a button is pressed but I keep getting the error in the title.
I'm calling the function like so:
echo("<th><input type='button' name = 'Attack_Btn' onclick = 'FightPlayer(".$row['username'].")' value ='Attack'></th>");
just say the username that it gets from $row['user... is James the error will display
index.php:1 Uncaught ReferenceError: casualjames is not defined
This is the code that it calls next
function FightPlayer(enemyName){
var xhttpe;
if (window.XMLHttpRequest) {
xhttpe = new XMLHttpRequest();
} else {
xhttpe = new ActiveXObject("Microsoft.XMLHTTP");
}
xhttpe.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
BattlePlayers();
}
};
xhttpe.open("GET", "FightPlayer.php?enemyname="+enemyName, true);
xhttpe.send();
}
and then it calls my php script passing in the variable enemyname for it to use
<?php
session_start();
include 'Training.php';
$link = mysqli_connect("","","","");
if (isset($_SESSION['username'])) {
$enemyname = $_REQUEST["enemyname"];
echo $enemyname;
$energyRemove = 1;
$ExperienceGain = 1;
$sql = "SELECT * FROM userstats WHERE username = '$enemyname'";
$result = mysqli_query($link,$sql);
$row = mysqli_fetch_assoc($result);
$Defence = $row["Defence"];
$winChance = CalculateWinChance($link,$Defence);
$sql = "SELECT Energy FROM userstats WHERE username = '".$_SESSION['username']."'";
$result = mysqli_query($link,$sql);
$row = mysqli_fetch_assoc($result);

}else{

}
echo "";
}

}

I'm not sure where the error is actually happening I've put my scripts through online code checkers and it all returns normal. Where am I going wrong here?
The string you're passing into your javascript function needs to be quoted, or else it thinks that it's a variable:
echo("<th><input type='button' name = 'Attack_Btn' onclick = 'FightPlayer(\"".$row['username']."\")' value ='Attack'></th>");
Your error is most likely with the onclick...you need to escape quotes in the function argument here:
echo("<th><input type='button' name = 'Attack_Btn' onclick = 'FightPlayer(\"".$row['username']."\")' value ='Attack'></th>");
I created an array for town name, "Auckland" and "Hamilton", but the response from php is always empty, any idea?
UPDATE:
after debugging, I found that the problem is in php query
" where town = '$town' ", once i deleted this line, the rest works perfectly.
But I still can't figure out why :<
javascript:
var _addNewTowntoList = function(){
if (_request.readyState == 4) {
if (_request.status == 200) {
var data = JSON.parse(_request.responseText);
if(data.length == 0){
alert("No such town");
return;
}
var t = data[0].town;
var o = data[0].outlook;
var min = data[0].min_temp;
var max = data[0].max_temp;
var witem = new WLine(t,o,min,max);
console.log(t+" "+o+" "+min+" "+max);
_list.push(witem);
}
}
}
here is the php
$town = $POST_['town'];
$query = "Select * From weather WHERE town = '$town'";
$result = mysqli_query($conn, $query);
//create array for data
$data = array();
while($row = mysqli_fetch_assoc($result))
{
$data[] = $row;
}
echo json_encode($data);
change this
$town = $POST_['town'];
> $query = "Select * From weather WHERE town = '$town'";
to
$town = $_POST['town'];
$query = "Select * From weather WHERE town = '".$town."'";
Remember to properly escape the query string
$town = mysqli_real_escape_strin($conn, $_POST['town']);
Because else your script is opened to SQL Injection attack
The other thing to mention here other than correct name for the $_POST is that you can use mysqli_fetch_all function to fetch all results at once and avoid the loop. For example
echo json_encode(mysqli_fetch_all($result, MYSQLI_ASSOC));
