I didn't understand how to get data from php by ajax.
Here is my javascript code :
$('#value').on('keyup', function(event){
event.preventDefault();
var form_data = $(this).serialize();
var sending = $("#sending").val();
var value = $("#value").val();
var recevied = $("#recevied").val();
$.ajax
({
type: "POST",
//async: true,
dataType : 'json',
url: "{{url('/calculate')}}",
data: {_token:"{{csrf_token()}}", sending:sending,value:value,recevied:recevied}
}).done( function(data){
//swal("Good job!", "Your personal information has been successfully updated!", "success")
$("#mainvalue").val(data)
console.log('Ajax was Successful!')
console.log(data)
}).fail(function(xhr, textStatus, error){
console.log(textStatus)
console.log(error)
});
});
here is my php code :-
public function index(Request $request)
{
$sending = $request->get('sending');
$value = $request->get('value');
$recevied = $request->get('recevied');
$relations = DB::table('tbl_relations')
->where('exid1',$sending)
->where('exid2',$recevied)
->select()
->first();
if ($relations != null) {
$rate = $relations->exrate2;
$mainvalue = $sending * $rate;
return $rate;
}else{
return $request->all();
}
}
How to restore $rate value into #mainvalue ?
well i guess you can try the following inside the php code :
$post = file_get_contents('php://input');

I would like to send my variable "var targetId" to my php file.
I try to make ajax request but nothing happens.
My js file :
$( ".project_item" ).click(function(e){
var targ = e.target;
var targetId = targ.dataset.id;
console.log(targetId);
$('.popUp').fadeIn("200");
$('header, main, footer').addClass('blur');
$.ajax({
url: 'function.php',
type: "POST",
data: {idVoulu: targetId},
success: function(data){
alert(data);
console.log(data);
}
});
});`
And my php file to get the data
$idProject = (isset($_POST['idVoulu'])) ? $_POST['idVoulu'] : 0;
if($idProject==0) { echo ' ID not found';}
Can you tell me what's going wrong?
Well I can't Find a problem on your code but you can try this may be this will help you
var mydata = "idVoulu='+targetId+'"; // make a string
$.ajax({
url: 'function.php',
type: "POST",
data: mydata,
success: function(data){
alert(data);
console.log(data);
}
});
So, i made this and it works:
My js:
$( ".project_item" ).click(function(e) {
var targ = e.target;
var targetId = targ.dataset.id;
$('.popUp').fadeIn("200");
$('header, main, footer').addClass('blur');
$.post('../function.php', { id: targetId }, function(response) {
console.log("reponse : ", response)
});
My php :
if (isset($_POST['id'])) {
$newID = $_POST['id'];
$response = 'Format a response here' . $newID;
return print_r($response);
}
I'm trying to get result and alert it if the solicitude was successful or not on the PHP file, it worked (because changed the results) but the AJAX didn't show alerts (No error and no "true")
js:
function addentrys() {
var nwentry = {};
el = document.getElementById('addname').value;
eldmn = document.getElementById('adddomain').value;
nwentry.name = el;
nwentry.domain = eldmn;
$.ajax({
type: 'POST',
url: 'api/domain',
dataType: 'json',
data: nwentry
}).done(function(data) {
alert(data);
});
}
php:
$app->post('/domain', function () {
$jsonContents = file_get_contents('data/data.json');
$name = $_POST['name'];
$domain = $_POST['domain'];
$data = json_decode($jsonContents, true);
$last_item = end($data);
$last_item_id = $last_item['id'];
$data[] = array(
'name' => $name,
'domain' => $domain,
'id' => $last_item_id+1
);
$json = json_encode($data);
file_put_contents('data/data.json', $json);
return true;
});
The result is probably not in JSON format, so when jQuery tries to parse it as such, it fails. You can catch the error with error: callback function.
You don't seem to need JSON in that function anyways, so you can also take out the dataType: 'json' row.
i return from php page an echo for test:
$('#form').on('submit', function (e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: 'https://capelladb.000webhostapp.com/textExample.php',
data: $('#form').serialize(),
success: function (data) {
var compare = data.localeCompare('testest');
console.log(data);
console.log(compare);
}
});
});
});
Just for test, the data returns in the success method is typeof "string" with "testest", but when im comapre to 'testest', is return -1 into "compare" variable. why it happen ?

the PHP:
<?php
header("Access-Control-Allow-Origin: *");
$servername = "localhost";
$username = "id1635462_capellam";
$password = "capella2017";
$dbname = "id1635462_capella";
$userInput = $_POST['username'];
$passwordInput = $_POST['password'];
echo $userInput . $passwordInput;
?>
Your data has empty spaces within.
You need to trim it, using .trim().
See the code below:
$('#form').on('submit', function (e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: 'https://capelladb.000webhostapp.com/textExample.php',
data: $('#form').serialize(),
success: function (data) {
var compare = data.trim().localeCompare('testest');
console.log(data);
console.log(compare);
}
});
});
});
Working example:
window.onload = function() {
var data = 'testest ';
var test = data.localeCompare('testest');
console.log('Not trimmed: ' + test);
var test = data.trim().localeCompare('testest');
console.log('Trimmed: ' + test);
};
I have this PHP CodeIgniter code where in the view I am getting input from a text field. Using AJAC I am trying to pass this value to the controller using GET request. The controller will then call a function from my model to retrieve a database record matching the search criteria.
For some reason it doesn't work. I tried to do a var dump in the controller to see if the value is passed by AJAX, but I am not getting anything. Any ideas what I am doing wrong and why I can't receive the form value in the controller?
View:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.13.3/jquery.min.js"</script>
<script language="Javascript">
$(document).ready(function () {
$('#submitbutton').click(function () {
$.ajax({
url: "../../index.php/testcontroller/getdatabasedata",
data: {
'searchvalue' : $('#inputtext').val()
},
method: 'GET'
}).done(function (data) {
var dataarray = data.split('##');
$('#question').html(dataarray[ 1 ]);
$('#answer1').html(dataarray[ 2 ]);
});
return false;
});
});
</script>
</body>
Controller
public function getdatabasedata()
{
$this->load->model('testmodel');
$year = $this->input->get('searchvalue');
//I TRIED TO DO A VARDUMP($YEAR) BUT I DON'T GET ANYTHING!
$movie = $this->testmodel->findquestion($year);
$moviesstring = implode(",", $movie);
echo $moviesstring;
}
Model
function findquestion($searchvalue)
{
$this->db->where('answer1', $searchvalue);
$res = $this->db->get('questions');
var_dump($res)
if ($res->num_rows() == 0)
{
return "...";
}
$moviearray = $res->row_array();
return $moviearray;
}
Script:
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js">
</script>
<script language="Javascript">
$(document).ready(function ()
{
$("#submitbutton").bind("click",function()
{
var target_url = '<?php echo(base_url()."testcontroller/getdatabasedata") ; ?>';
var data = {'searchvalue' : $('#inputtext').val() };
$.ajax ({
url : target_url,
type: 'GET',
data: data,
cache: false,
success: function(controller_data)
{
var dataarray = controller_data.split('#');
$('#question').html(dataarray[1]);
$('#answer1').html(dataarray[3]);
},
});
return false;
});
});
</script>
.bind("click",function() - add quotes to click event.
var dataarray = controller_data.split('#'); - split
data caracter must match character in implode function in controller.
Controller:
public function getdatabasedata(){
$this->load->model('testmodel');
$year = $this->input->get('searchvalue');
$movie = $this->testmodel->findquestion($year);
$separated = implode("#", $movie);
echo $separated;
}
Hope this helped.
I will share my usual ajax code that I use in my views , make sure your base url is correct
$("#submitbutton").bind("click",function()
{
var target_url = '<?php echo(base_url()."testcontroller/getdatabasedata") ; ?>';
$.ajax
(
{
url : target_url,
type: "GET",
// data: {'searchvalue' : $('#inputtext').val()},
cache: false,
success: function(data)
{
alert(data);
},
error: function(jqXHR, textStatus, errorThrown)
{
alert("error during loading ....");
}
});
});// end loading via ajax
and in your controller just echo something
public function getdatabasedata()
{
//$this->load->model('testmodel');
//$year = $this->input->get('searchvalue');
//I TRIED TO DO A VARDUMP($YEAR) BUT I DON'T GET ANYTHING!
//$movie = $this->testmodel->findquestion($year);
//$moviesstring = implode(",", $movie);
//echo $moviesstring;
echo "hello";
}
I'm trying to send an AJAX request to a php file, and I want the php file to respond with a JSON object, however the AJAX function is continually failing when declare that I specifically want JSON returned. Any help will greatly be appreciated.
this is my ajax function
function getMessages(){
$.ajax({
type: 'POST',
url: 'viewInbox',
dataType: 'json',
success: function(msg){
//var content = data.substr(0, data.indexOf('<'));
populateMessages(msg);
},
error: function(){
alert("ERROR");
}
});
}
and this is the relevant code for the php file
$message_links[] = array();
.....
while($run_message = mysql_fetch_array($message_query)){
$from_id = $run_message['from_id'];
$message = $run_message['message'];
$user_query = mysql_query("SELECT user_name FROM accounts WHERE id=$from_id");
$run_user = mysql_fetch_array($user_query);
$from_username = $run_user['user_name'];
$message_links[] = array("Hash" => "{$hash}", "From" => "{$from_username}", "Message" => "{$message}");
// is that not valid json notation???
}
}
echo json_encode( $message_links, JSON_FORCE_OBJECT);
//$arr = array("a" => "1", "b" => "2");
//echo json_encode($arr);
UPDATE:
Well, I ended up switching the dataType request to 'html' and I am now able to actually access these values via JSON, however, I would still like to know why the php file was not returning correct JSON notation. Any insight would be awesome, cheers.
function getMessages(){
$.ajax({
type: 'POST',
url: 'viewInbox',
dataType: 'html',
success:function(msg){
var content = msg.substr(0, msg.indexOf('<'));
msg = JSON.parse(content);
populateMessages(msg);
},
error: function(xhr, textStatus, errorThrown) {
alert(errorThrown);
alert(textStatus);
alert(xhr);
}
});
}
function populateMessages(data){
var out = '';
var json;
for (var i in data){
var my_string = JSON.stringify(data[i],null,0);
json = JSON.parse(my_string);
alert(json.Hash);
out += i + ': ' + my_string + '\n';
}
alert(out);
}
You need to set the header as json type before your echo in PHP:
header('Content-Type: application/json');
