I want to transfer data to the controller using ajax. Here is the ajax code
$(document).on("click", '#bt1', function(e)
{
e.preventDefault();
$.ajax({
url:"/insert_",
type:"post",
data:{
name2:"admin",
_token: $("input[name='_token']").val()
}
})
});
Here is the code in the controller
public function insert_db(Request $request)
{
dd($request->all());
}
Here is the layout code
<form action="/insert_" method="post">
#csrf
<input type="submit" id="bt1" value="do it">
</form>
Here is code в web.php
Route::post('/insert_',"StudentController#insert_db");
Displays this
Why does display this? Please help
Your jquery ajax request should look like below:
$(document).on("click", '#bt1', function(e)
{
e.preventDefault();
$.ajax({
url:"/insert_",
type:"post",
data:{
"name":"test",
_token: $("input[name='_token']").val()
}
})
});
or
$(document).on("click", '#bt1', function(e)
{
var payload = JSON.stringify({
'name': 'test',
'_token': $("input[name='_token']").val()
});
e.preventDefault();
$.ajax({
url:"/insert_",
type:"post",
data:payload
})
});
There is nothing wrong with your code, but i will love to get the string part by coding it like this
$(document).on("click", '#bt1', function(e)
{
e.preventDefault();
$.ajax({
url:"/insert_",
type:"post",
data:{
"name2":"admin",
_token: $("input[name='_token']").val()
}
})
});
noticed that i changed name2:"admin" to "name2":"admin"

I am trying to learn Laravel9. For this I have Created a Controller, a model and blade view file. Below is my vatprofile.blade.php file code
<script type="text/javascript" src="https://code.jquery.com/jquery-2.0.2.js"></script>
<script>
$(document).ready(function () {
$.ajax({
type: "get",
url: "/vatprofile",
dataType: "json",
success: function (response) {
alert(response);
}
});
});
</script>
And this is my Rout,
Route::get('/vatprofile',
[VatProfileController::class,'index']);
And Below is my Controller Function
public function index(){
return response()->json(['success'=>'Record is successfully added']);
}
It is not Giving Error, Not printing out any response. Only the Blank Page is Showing up. Can you Correct me Pls
Please try this:
<script type="text/javascript" src="https://code.jquery.com/jquery-2.0.2.js"></script>
<script>
$(document).ready(function () {
$.ajax({
type: "get",
url: "{{ url('vatprofile') }}",
dataType: "json",
success: function (response) {
alert(response);
}
});
});
</script>
Button code
this is my button code with id 123
<button type="submit" class="addto" id="123">Add to cart</button>
ajax code
This is my ajax code
$(document).ready(function(){
$('.addto').click(function (event) {
event.preventDefault();
$id=this.id;
//alert($id);
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$.ajax({
url: '/test', //route url
dataType:"json",
type:"POST",
data:{id:this.id},
success: function(result){ //success function
alert("success"); //test alert
}});
});
});
Route code
this is my route code
Route::match(['get','post'],'/test','ajaxcontrol#test'); //route url
Controller code:
How to solve this, i have included all the imports
class ajaxcontrol extends Controller
{
public function test(Request $request){
$valu=$request->id;
echo json_encode($valu);
}
}
Try to change your ajax like this:
$(document).ready(function(){
$('.addto').click(function (event) {
event.preventDefault();
id=this.id;
//console.log(id);
$.ajax({
url: "{{ url('/test') }}", //route url
dataType:"json",
type:"POST",
data:{
id:id,
"_token": "{{ csrf_token() }}",
},
success: function(result){ //success function
alert("success"); //test alert
}});
});
});
Form submit is not happened in this scenario..
$.ajax({
type: "POST",
async: false,
url: base_url+"register/registration_val",
data: "register_first_name="+first_name,
success: function(data){
$('#inferiz').html(data);
},
error: function(){
alert('error');
}
In your view you can add this:
<script type="text/javascript">
var base_url = "<?php print base_url(); ?>";
</script>
Plus try to alert and see the value of final url in ajax i.e alert(url);
Try adding a id to the firstname input
<script type="text/javascript">
$(document).on('submit','#form-reg',function(){ // #form-reg is id on form open tag
$.ajax({
url: "<?php echo base_url('register/registration_val');?>",
type: 'POST',
data: {
firstname: $('#firstname').val(),
},
dataType: 'html', // I perfer to use json
success: function(data){
$('#inferiz').html(data);
},
error: function(){
alert('error');
}
}
});
});
</script>
I would use dataType: json much easier that way to get data from controller
You used data: "register_first_name="+first_name, it's not correct. Correction is data: {register_first_name:first_name},
base_url like this var base_url = <?php echo base_url(); ?>
So, Bellow final code :
<script type="text/javascript">
jQuery(document).ready(function ($) {
var base_url = <?php echo base_url(); ?>
$.ajax({
url: base_url+"register/registration_val", // Url to which the request is send
type: "POST", // Type of request to be send, called as method
data: {register_first_name:first_name}, // Data sent to server, a set of key/value pairs representing form fields and values
contentType: false, // The content type used when sending data to the server. Default is: "application/x-www-form-urlencoded"
}).done(function (data) {
$('#inferiz').html(data);
}).fail(function (data) {
console.log('failed');
});
}(jQuery));
</script>
Please verify your view part that whether you provided id same as in ajax function.
view part:
<form id="form-reg">
<input name="firstname" id="firstname" type="text" required placeholder="Enter firstname " >
<span id="name_validation" class="text-danger"></span>
<button name="submit" id="submit_button" onClick="myFunction();" >submit</button>
</form>
Then correct the base url path which has to be given inside php tag.
function myFunction() {
$.ajax({
url: "<?php echo base_url();?>register/registration_val",
type: "POST",
data:'firstname='+$("#firstname").val(),
success: function(msg)
{
alert('done..!');
}
});
}
This is ajax request
<script type="text/javascript">
{literal}
$(document).ready(function(){
$("#S1").change(function()
{
var IDCat=this.value;
alert(IDCat);
$.ajax({
type: "GET",
url: 'product_modify.php',
data: {IDCat:IDCat},
success: function(data)
{
alert(data);
alert("success");
}
});
});
});
{/literal}
</script>
And this is php codes
if(isset($_GET['IDCat'])){
$idc= $_GET['IDCat'];
echo $idc;
}
there is the problem echo $idc; doesn't work ? where is the problem ?
var IDCat=this.value;
should be
var IDCat=$(this).val();

controller.php -simple php file that return json array:
<?php
$arr=array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
echo json_encode($arr);
?>
Thanks
The form has a default action with a type="submit" button, which is submitting, so you'll need to stop that from happening by adding return false or event.preventDefault() , like this:
$(document).ready(function() {
$('#submit-html').click(function(e) {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType:'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function (i, elem) {
$('#array-values').append('<div>'+elem+'</div>');
});
}
});
return false;
//or e.preventDefault();
});
});
Without this, the form is submitting as it normally would with no JavaScript, leaving the page. So effectively it's doing a refresh, instead of AJAX submitting your form (which doesn't have time to complete...because you left :)
An element of type=submit inside a <form> will perform the form request when clicked on.
You need to abort the default behavior by running event.preventDefault() inside the click callback.
My guess is that the form is submitting and refreshing the page before the ajax has a chance to respond.
Try putting return false; at the end of the click handler.
$('#submit-html').click(function() {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType: 'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function(i, elem) {
$('#array-values').append('<div>' + elem + '</div>');
});
}
});
return false;
});
Of course you'll have the same issue if the user hits Enter in one of the fields. Unless you're preventing the Enter key from submitting the form, you may want to the handle the event using the submit() handler.
$('#parse-form').submit(function() {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType: 'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function(i, elem) {
$('#array-values').append('<div>' + elem + '</div>');
});
}
});
return false;
});
Try using submit() http://api.jquery.com/submit/ , this should work with keyboard events as well as clicks. You can use serialize() to get any form data into the ajax objects data variable.
