How to ajax post with array of object data in laravel

I want to ask you here. I have an array of objects like this on this array of objects. I want to use it as a data post to the controller when I run it. There's an error. Error CSRF missmatch.
my code
var dataarray=[];
dataarray.push({
_token:$('#_token').val(),
no_draft :$('#no_draft').val(),
no_transaction :$('#no_transaction').val(),
currency :$('#currency').val(),
kurs_total_idr :$('#kurs_total_idr').val(),
no_referensi :$('#no_referensi').val(),
grant_total_ap :$('#grand_total_ap').val(),
payment_type :$('#payment_type').val(),
grant_total_payment :$('#grand_total_payment').val(),
payment_account :$('#payment_account').val(),
payment_account_id :$('#payment_account_id').val(),
note :$('#note').val(),
date :$('#datepicker1').val(),
grant_total_payment :$('#grand_total_payment').val(),
status :$('#status').val(),
acc_tra_ap_payment_detail:acc_tra_ap_payment_detail,
});
var url = "";
savemethod="add"
if (savemethod === 'add') {
url = "<?php echo url('ap-payment/store') ?>";
} else {
url = "<?php echo url('/updatepegawai') ?>";
}
$.ajax({
url: url,
contentType: 'application/json',
type: "POST",
data: dataarray,
dataType: "JSON",
success: function (data) {
console.log("berhasil",data);
},
error: function (request, status, error) {
alert("Error json " + error);
}
});

You will have to define the csrf token in the main array and not in the object.
so your data array has to look like:
dataarray =
[
_token:$('#_token').val(),
data: {...}
]
and then it should recognize the csrf token (make also sure that the vlaue is present)

Create variable in one script and use in another script. JQuery/HTML/JS

How can I turn the results from Script 1, Name, Email, Teamsinto variables I can use in script 2?
I am making an API call to fetch some JSON I then want to use certain values as text in a message I then send to slack.
Example.
$('.Name').html(data.user.name); // Returns John
$('.Email').html(data.user.email); // Returns John#John.com
$('.Teams').html(data.user.teams[0].name); // Returns JohnsTeam
var text = 'Hello my name is $Name + my email is $Email + From $Teams'
Output = Hello my name is John my email is John#John.com From JohnsTeam
Script 1
function currentUrl() {
return new Promise(function (resolve) {
chrome.tabs.query({
active: true,
currentWindow: true
}, function(tabs) {
resolve(tabs[0].url)
})
})
}
function userIdfromUrl(url) {
var parts = url.split('/')
return parts[parts.length - 1]
}
var authorizationToken = "xxxxxxxxxxxxxxxxxxxxxxxxx";
function myapiRequest(endpoint, options) {
$.ajax($.extend({}, {
type: 'GET',
dataType: "json",
success: function(data) {
$('.Name').html(data.user.name);
$('.Email').html(data.user.email);
$('.Teams').html(data.user.teams[0].name);
},
url: "https://api.myapi.com/" + endpoint,
headers: {
"Authorization": "Token token=" + authorizationToken,
"Accept": "application/vnd.myapi+json;version=2"
}
},
options));
}
currentUrl()
.then(function (url) {
return userIdfromUrl(url)
})
.then(function (userId) {
return myapiRequest('users/' + userId + '?include%5B%5D=contact_methods&include%5B%5D=teams')
})
.then(function (data) {
console.log(data.user.name)
console.log(data.user.email)
console.log(data.user.teams[0].name)
})
Script 2
$(document).ready(function(){
$('#contact-submit').on('click',function(e){
e.preventDefault();
var url = 'https://hooks.slack.com/services/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
var text = 'This is a message'
$.ajax({
data: 'payload=' + JSON.stringify({
"text": text // What I want to dynamically change
}),
dataType: 'json',
processData: false,
type: 'POST',
url: url
});
});
});

One great solution is to set the variable you get from the response in the HTML5 localstorage as follows:
Inside ur success:
success: function(data) {
localStorage.setItem("urdata",JSON.stringify(data));
}
In the other script, u can retrieve the data like this:
var data = localStorage.getItem("urdata"); data = JSON.parse(data);

No data receive in Jquery from php json_encode

I need help for my code as i have been browsing the internet looking for the answer for my problem but still can get the answer that can solve my problem. I am kind of new using AJAX. I want to display data from json_encode in php file to my AJAX so that the AJAX can pass it to the textbox in the HTML.
My problem is Json_encode in php file have data from the query in json format but when i pass it to ajax success, function(users) is empty. Console.log also empty array. I have tried use JSON.parse but still i got something wrong in my code as the users itself is empty. Please any help would be much appreciated. Thank you.

});

Remove this in this.car_rent_id1 and cache: false this works with HEAD and GET, in your AJAX you are using POST but in your PHP you use $_GET. And car_rent_id is not defined, your function $_GET(q,s) requires two parameters and only one is passed.
$(document).ready(function() {
function $_GET(q,s) {
s = (s) ? s : window.location.search;
var re = new RegExp('&'+q+'=([^&]*)','i');
return (s=s.replace(/^\?/,'&').match(re)) ?s=s[1] :s='';
}
var car_rent_id1 = $_GET('car_rent_id'); // missing parameter
car_rent_id.value = car_rent_id1; // where was this declared?
$.ajax({
type: 'POST',
url: "http://localhost/ProjekCordova/mobile_Rentacar/www/php/car_detail.php",
dataType: "json",
data: { car_rent_id: car_rent_id1 },
success: function(users) {
console.log(users);
$('#car_name').val(users.car_name);
}
});
});
You can also use $.post(), post is just a shorthand for $.ajax()
$(document).ready(function() {
function $_GET(q,s) {
s = (s) ? s : window.location.search;
var re = new RegExp('&'+q+'=([^&]*)','i');
return (s=s.replace(/^\?/,'&').match(re)) ?s=s[1] :s='';
}
var car_rent_id1 = $_GET('car_rent_id');
car_rent_id.value = car_rent_id1;
$.post('http://localhost/ProjekCordova/mobile_Rentacar/www/php/car_detail.php', { car_rent_id: car_rent_id1 }, function (users) {
console.log(users);
$('#car_name').val(users.car_name);
});
});
and in your PHP change
$car_rent_id = $_GET['car_rent_id'];
to
$car_rent_id = $_POST['car_rent_id'];

Here is a code skeleton using .done/.fail/.always
<script
src="https://code.jquery.com/jquery-1.12.4.min.js"
integrity="sha256-ZosEbRLbNQzLpnKIkEdrPv7lOy9C27hHQ+Xp8a4MxAQ="
crossorigin="anonymous"></script>
<script>
$(function(){
$.ajax({
url: 'theurl',
dataType: 'json',
cache: false
}).done(function(data){
console.log(data);
}).fail(function(data){
console.log(data);
}).always(function(data){
console.log(data);
});
});
</script>
I've adapted your code, so you can see the error, replace the ajax call with this one
<script>
$.ajax({
url: "theurl",
dataType: "json",
data: { car_rent_id: car_rent_id1 },
success: function(users) {
console.log(users);
$('#car_name').val(users.car_name);
},
error: function(data) {
console.log(data);
alert("I failed, even though the server is giving a 200 response header, I can't read your json.");
}
});
</script>

A couple of recommendations on this, I would follow jQuery API to try an see where the request is failing http://api.jquery.com/jquery.ajax/. Also, I would access the ids for the input fileds with jQuery. e.g.: $("#theID").val().

Serialzing form and posting ajax to function

I am trying to pass the form field values to a php function located into a file. The problem is that I can't understand how to pass that serialized form data to the function from this ajax to a function in php.
$('#insert_news').submit(function(event) {
event.preventDefault();
var form = $('#insert_news').serialize();
$.ajax({
type: 'POST',
url: 'includes/ajax.php',
data: {
action: 'insert_news',
$('#insert_news').serialize(); // how do I add this data here?
},
success: function(datas) {
$('#message').html(datas).show() /*fadeIn(1000).fadeOut(1000)*/ ;
}
});
});
This ajax passed the values to the file ajax.php right beyond. And from ajax.php is called the function located in functions.php.
ajax.php
if (isset($_POST['action']) && $_POST['action'] == 'insert_news') {
$cp->insert_into_table('newss', array(
'NewsTitle' => $_POST['title'],
'NewsDescrption' => $_POST['description'],
'Date' => date('Y-m-d H:i:s'),
'status' => '1'
)
);
}
function.php
public function insert_into_table($table_name, array $data){
foreach($data as $col=>$value) {
$cols[] = $col;
$values[] = '\''.$value.'\'';
}
$cols = implode(', ', $cols);
$values = implode(', ', $values);
$this->db->query("INSERT INTO $table_name ($cols) VALUES ($values)");
echo "INSERT INTO $table_name ($cols) VALUES ($values)";
}

The issue is serialize() produces a URL encoded key value paired string, so you can't mix that with your data object.
You can use serializeArray() to get an array of objects, representing the form elements, then iterate over them and add them to a data object:
var data = { action: 'insert_news' };
$.each($('#insert_news').serializeArray(), function(){
data[this.name] = this.value;
});
$.ajax({
type: 'POST',
url: 'includes/ajax.php',
data: data,
success: function(datas) {
$('#message').html(datas).show() /*fadeIn(1000).fadeOut(1000)*/ ;
}
});
Side note: your PHP code is vulnerable to SQL Injection. Consider using a Prepared Statement instead of concatenating user input into the SQL.

You can pass serialized data via ajax to a function the way you are doing but your code needs slight modification.
$('#insert_news').submit(function(event) {
event.preventDefault();
var form = $('#insert_news').serialize();
$.ajax({
type: 'POST',
url: 'includes/ajax.php',
data: {
action: 'insert_news',
serializedData: form // use variable to assign data here
},
success: function(datas) {
$('#message').html(datas).show() /*fadeIn(1000).fadeOut(1000)*/ ;
}
});
});

I think you can use alternate like this
First : add hidden input for action on your form
<input type="hidden" name="action" value="insert_news"/>
Then your ajax post like this
$('#insert_news').submit(function(event) {
event.preventDefault();
$.ajax({
type: 'POST',
url: 'includes/ajax.php',
data: $(this).serialize(), // $(this) is from <form id="insert_news">
success: function(datas) {
$('#message').html(datas).show() /*fadeIn(1000).fadeOut(1000)*/ ;
}
});
});
And then use print_r on your ajax.php
print_r($_POST);

$('#insert_news').submit(function(event) {
var name = $("#t1").val();
var pass = $("#t2").val(); //add more var as u need
var key = 0;
var formName = new FormData();
formName.append(key++,name)
formName.append(key++,pass) //append the the var to formdata
$.ajax({
url : 'includes/ajax.php',
dataType : 'text',
cache : false,
contentType : false,
processData : false,
data : formName,
type : 'post',
success : function(data){
$('#message').html(data).show() /*fadeIn(1000).fadeOut(1000)*/ ;
}
});
});
this works fine for me :-)

ajax to pass array value , how to fetch array on called page

I have array containg image path ,
GenerateReport[0] ="../images/Desert1.jpg"
GenerateReport[1] ="../images/Desert2.jpg"
GenerateReport[2] ="../images/Desert3.jpg"
GenerateReport[3] ="../images/Desert4.jpg"
GenerateReport[4] ="../images/Desert5.jpg"
I am trying to pass this array with following code,
$.ajax({
type: "POST",
url: "generatePdf.php",
data: {
genRep: "sample value"
},
success: function(data) {
alert(data);
console.log('getting '+data);
}
});
sample value is passed successfully , but how can i pass array to ajax and use it on another page?? i tried passing array and using with below code but it is not working
$data1 = $_REQUEST['genRep'];
echo "tested".$data1[0];

Try like
genRep = [];
$.ajax({
type: "POST",
url: "generatePdf.php",
data: {
genRep: GenerateReport
},
success: function(data) {
alert(data);
console.log('getting '+data);
}
});
It will send your array as genRep

try to use json object. in object you can store your images path
var data=[]; // array
var data[0] = 'something';
var data[1] = 'something1';
var data = { 'name': name, 'email' : email, 'contact' : contact, 'type' : type, 'msg' : msg }; // object
$.ajax({
url : 'contact.php',
type : 'POST',
data : {contact:JSON.stringify(data)}, // for json object
data : {contact: data}, // for array
success : function (msg)
{
alert(msg);
}
})
contact.php
$info = $_POST['contact'];
$info = json_decode($info,true); // for json object
echo $info.name; // for json object
echo $info[0]; // will print something...

$arr = array();
$arr[0] = "Mark Reed";
$arr[1] = "34";
$arr[2] = "Australia";
echo json_encode ($arr);
use this on the php page
and use the following to get the output
success:function(msg){
id_numbers = JSON.parse(msg);
alert(id_numbers)
}

Try:
$.ajax({
url: "generatePdf.php",
type: 'POST',
data: form_data,
dataType:"json",
success: function(data) {
alert(data[0]);
}
On the PHP side, you'll be wanting to print:
print json_encode($photos);
Made Some Change
print json_encode(array("photolist"=>$photos));
Then on the server, you'd access these with:
data.photolist[0]; //First photo

I have tested it, this will definitely work !
JS:
var GenerateReport = [];
GenerateReport[0] ="../images/Desert1.jpg";
GenerateReport[1] ="../images/Desert2.jpg";
GenerateReport[2] ="../images/Desert3.jpg";
GenerateReport[3] ="../images/Desert4.jpg";
GenerateReport[4] ="../images/Desert5.jpg";
$.ajax({
type: 'POST',
url: 'generatePdf.php',
data: 'image_array='+GenerateReport,
success: function(msg) {
alert(msg);
}
});
generatePdf.php :
<?php
$image_string = $_POST['image_array'];
$image_array = explode(",", $image_string);
print_r($image_array);
?>
Then you can loop over the $image_array to get the values.

try this
GenerateReport[0] ="../images/Desert1.jpg"
GenerateReport[1] ="../images/Desert2.jpg"
GenerateReport[2] ="../images/Desert3.jpg"
GenerateReport[3] ="../images/Desert4.jpg"
GenerateReport[4] ="../images/Desert5.jpg"
corrected code:
var imagedata = '';
$.each(GenerateReport,function(index,value))
{
if(imagedata=='')
{
imagedata = imagedata +'image'+index+'='+value;
}
else
{
imagedata = imagedata +'&image'+index+'='+value;
}
});
$.ajax({
type: "POST",
url: "generatePdf.php",
data: imagedata //pass string imagedata
success: function(data) {
alert(data);
console.log('getting '+data);
}
});
imagedata should have sting like this:
image1=../images/Desert1.jpg&image2=../images/Desert2.jpg and so on

if(isset($_REQUEST['genRep']))
{
$data = $_REQUEST['genRep'];
print_r($data1);
echo "tested".$data1[0];
createPdf($data);
}
My code was correct , there was no value on index 0 , thats why it was not printing anything .My Mistake !!!
