I'm using zend framework, i would like to get POST data using Jquery ajax post on a to save without refreshing the page.
//submit.js
$(function() {
$('#buttonSaveDetails').click(function (){
var details = $('textarea#details').val();
var id = $('#task_id').val();
$.ajax({
type: 'POST',
url: 'http://localhost/myproject/public/module/save',
async: false,
data: 'id=' + id + '&details=' + details,
success: function(responseText) {
//alert(responseText)
console.log(responseText);
}
});
});
});
On my controller, I just don't know how to retrieve the POST data from ajax.
public function saveAction()
{
$data = $this->_request->getPost();
echo $id = $data['id'];
echo $details = $data['details'];
//this wont work;
}
Thanks in advance.
Set $.ajax's dataType option to 'json', and modify the success callback to read from the received JSON:
$('#buttonSaveDetails').click(function (){
var details = $('textarea#details').val();
var id = $('#task_id').val();
$.ajax({
type: 'POST',
dataType: 'json',
url: 'http://localhost/myproject/public/module/save',
async: false,
// you can use an object here
data: { id: id, details: details },
success: function(json) {
console.log(json.id + ' ' + json.details);
}
});
// you might need to do this, to prevent anchors from following
// or form controls from submitting
return false;
});
And from your controller, send the data like this:
$data = $this->_request->getPost();
echo Zend_Json::encode(array('id' => $data['id'], 'details' => $data['details']));
As a closing point, make sure that automatic view rendering has been disabled, so the only output going back to the client is the JSON object.
Simplest way for getting this is:
$details=$this->getRequest()->getPost('details');
$id= $this->getRequest()->getPost('id');
Hope this will work for you.

I trying to use an AJAX PUT request to update a row in my database and I am trying to send the request to my controller. This is my AJAX call:
$('#edit-trucks').on('click',function(){
var truckNo = $('#XA').val();
var truckOwner = $('#truck-owner').val();
var vehicle_number = $('#vehicle-number').val();
var capacity = $('#capacity').val();
var end_of_insurance = $('#end-of-insurance').val();
var end_of_kteo = $('#end-of-KTEO').val();
var truckCode = $('#truck-code').val();
var leased = $('#leased').val();
var truckModel = $('#truck-model').val();
$.ajax({
url: 'editTruck',
type: 'put',
data: {
truckNo: truckNo,
truckOwner: truckOwner,
vehicle_number: vehicle_number,
capacity: capacity,
end_of_insurance: end_of_insurance,
end_of_kteo: end_of_kteo,
truckCode: truckCode,
leased: leased,
truckModel: truckModel
},
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
contentType: 'application/json',
dataType: 'JSON',
success: function(){
console.log('success');
},
error: function(){
console.log('something went wrong');
}
});
});
So far so good. If I console.log() my data is seems I can get them from the form. I am using Laravel Collective for the form:
{!!Form::open(array('action' => ['Trucks#editTruck'], 'method' => 'put')) !!}
and my route is the following:
Route::put('/editTruck', 'Trucks#editTruck',function(){ });
Now I am using Request $request in the parameters of the controller but somehow it looks like I cannot get the incoming values. For example the following var_dump will say NULL.
public function editTruck(Request $request)
{
$data = $request->input('truckNo');
var_dump($data);
}
Same happens if I use
$data = $request->truckNo;
instead. So I am wondering how can I get the values that are been sent to my controller with my AJAX call? Why am I getting NULL values?
What I was planning to do is:
public function editTruck(Request $request)
{
$singleTruck = Truck::find($request->truckNo);
$singleTruck->truckNo = $request->input('truckNo');
$singleTruck->truckOwner = $request->input('truckOwner');
........
$singleTruck->save();
}
You can find the answer here:
https://laravel.io/forum/02-13-2014-i-can-not-get-inputs-from-a-putpatch-request
You should change your form method and method inside your js code to "post", and add extra field "_method" = "PUT"
probably it can help.
OK I found it. Looks like the AJAX was malformed. So here is how it should be written:
$('#edit-trucks').on('click',function(){
var truckNo = $('#XA').val();
var truckOwner = $('#truck-owner').val();
var vehicle_number = $('#vehicle-number').val();
var capacity = $('#vehicle_capacity').val();
var end_of_insurance = $('#end-of-insurance').val();
var end_of_kteo = $('#end-of-KTEO').val();
var truckCode = $('#truck-code').val();
var leased = $('#leasing').val();
var truckModel = $('#truck-model').val();
var outGoingData = {
'truckNo': truckNo,
'truckOwner': truckOwner,
'vehicle_number': vehicle_number,
'capacity': capacity,
'end_of_insurance': end_of_insurance,
'end_of_kteo': end_of_kteo,
'truckCode': truckCode,
'leased': leased,
'truckModel': truckModel,
};
var data = JSON.stringify(outGoingData);
$.ajax({
url: 'editTruck',
type: 'POST',
data: data, <!-- The error was here. It was data: {data}-->
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
contentType: 'application/json',
dataType: 'JSON',
success: function(response){
alert("The data should be "+ response);
},
error: function(){
console.log('skata');
}
});
});
I am using codeigniter version 3+, Jquery version 3+. I am trying to get data through ajax request but it does not return anything. And when I inspect and see its request url is wrong but did not get how i modify that.
Ajax request
var site_url = '<?=base_url()?>';
var id = $(this).find("option:selected").attr('value');
$.ajax({
type : 'POST',
dataType : 'json',
url: '<?=base_url()?>'+'index.php/talika_12/get_data_by_id_ajax',
data: {user_id:id},
success: function(data) {
alert(data);
$('#inst_name').text(data.talika_12_user_name);
$('#inst_account_no').text(data.talika_12_user_account_no);
}
});
Controller
public function get_data_by_id_ajax(){
$user_id = $_POST['user_id'];
$data = $this->talika_12_m->get_data_by_id($user_id);
$ajax_response_data = array(
'talika_12_user_name' => $data[0]->talika_12_user_name ,
'talika_12_user_account_no' => $data[0]->talika_12_user_account_no ,
);
echo json_encode($ajax_response_data);
}
Model
public function get_data_by_id($id){
$where_clause = array('talika_12_user_id' => $id);
$this->db->limit(1);
$val = $this->db->get_where('table_12', $where_clause)->result();
return $val;
}
Get request url is ( Request URL:http://localhost/test/codeIgniter/talika_12/%3C?=base_url()?%3Eindex.php/talika_12/get_data_by_id_ajax
)
Please try this code
var id = $(this).find("option:selected").attr('value');
$.ajax({
type : 'POST',
dataType : 'json',
url: "<?=base_url()?>index.php/talika_12/get_data_by_id_ajax'",
data: {user_id:id},
success: function(data) {
alert(data);
$('#inst_name').text(data.talika_12_user_name);
$('#inst_account_no').text(data.talika_12_user_account_no);
}
});
changed url portion url: "<?=base_url()?>index.php/talika_12/get_data_by_id_ajax'", otherwise you can use url:<?= site_url('talika_12/get_data_by_id_ajax')
I would search for the solution, but I don't know what exactly do I have to search.
The task is to grab texts with ID's (#ftext_1,..._2,..._3,..._4) in html file and send them to php file. After some manipulation with texts in php file I have to insert them back into their ID's in html file.
Here is the code:
var text_1_Replace = $('#ftext_1').text();
var text_2_Replace = $('#ftext_2').text();
var text_3_Replace = $('#ftext_3').text();
var text_4_Replace = $('#ftext_4').text();
$('#ID').on('click', function(){
var text= {
ftext_1: text_1_Replace,
ftext_2: text_2_Replace,
ftext_3: text_3_Replace,
ftext_4: text_4_Replace
}
var targetFile = 'ajax/file.php';
$.ajax({
method: 'post',
url: targetFile ,
data: JSON.stringify(text),
contentType: 'application/JSON'
}).done(function(data) {
console.log(data);
});
});
How do I edit .done function to place new texts in their old ID's(#ftext_1,..._2,..._3,..._4)? The variable with texts array is $result.
so the answer is :
}).done(function(data) {
var text = JSON.parse(data);
var text1 = text.ftext_1;
var text2 = text.ftext_2;
var text3 = text.ftext_3;
var text4 = text.ftext_4;
$('#ftext_1').text(text1);
$('#ftext_2').text(text2);
$('#ftext_3').text(text3);
$('#ftext_4').text(text4);
So, the last update for the topic: The real and nice answer is:
.done(function(data) {
var text = JSON.parse(data);
$.each(text, function(i, val){
$("#" + i).text(val);
});
This code is the solution to my question in this topic. Thank you all, who responded!
The best for you would be send named property that looks like this
$.ajax({
method: 'post',
url: targetFile ,
data: {data: text},
dataType: "json",
success: function(response){
$.each(response, function(element){
$("#"+element.name).text(element.text);
});
}
});
Then in your php you could easily iterate data from post
<?php
$data = $_POST['data'];
$response = [
];
foreach($data as $elementName => $text){
// some text management
$response[] = ['name' => $elementName, 'text' => $text];
}
return json_encode($response);
When you change your received values in php you put them in an array so that you
can call it later easily
PHP
$values = array("one"=>5,
"two"=>"something",
"three"=>$something);
echo json_encode($values);
You need to add
dataType:'json'
in Jquery since you're returning json
JQuery
$.ajax({
method: 'post',
url: targetFile ,
data: JSON.stringify(text), # or data: {"value1":value,"value2":value2},
contentType: 'application/JSON',
dataType:'json',
success: function(response){
console.log(response.one); #Will console 5
console.log(response.two); #Will console "something"
console.log(response.three); #Will console whatever $something holds in php
}
});
You can call it however you want it (response) or (mydata)...
And then you just type response.yourdata (that you declared in php)
Can someone please show me the correct way I can add these two lines of code
data: {name: info, me: '<?php echo $me; ?>'},
data: dataString ,
So that I can send them in a $_POST to my action.php , I have tried several ways to do this but cannot get both of them successfully to be passed on to my action_comments.php I understand I'm missing something possible when using data: below or have not correctly formatted my code . I'm a total beginner with very little experience so sorry if I lack good practice but hopefully can be better from my debugging . Thanks to anyone who helps me get passed this .
Here is complete code to give overview what Im doing
<script type="text/javascript">
$(function() {
// call the submit button ref: name
$(".submit_button").click(function() {
declare textcontent
var textcontent = $("#content").val();
//dataString = 'content' globel var
var dataString = 'content='+ textcontent;
declare info
var info = $('#name').val();
// option no text inputted
if(textcontent=='')
{
// show message if no text
alert("Enter some text..");
$("#content").focus();
}
else
{
//display text animation loading
$("#flash").show();
$("#flash").fadeIn(400).html('<span class="load">Loading..</span>');
//var info equals the string
var info = $('#content').val();
//start ajax call
$.ajax({
type: "POST",
//path to my action.php
url: "actions/action_comment.php",
//Need to undestand how to correctly format these lines so
//they are both succesful when submitted to my action_comment.php
$me is declared (not-shown here it holds integer)
data: {name: info, me: '<?php echo $me; ?>'},
// pass the string from textarea to $_POST
data: dataString ,
// I can get one or the other to work but not both
cache: true,
// feed the success my data
success: function(html){
$("#show").after(html);
document.getElementById('content').value='';
$("#flash").hide();
$("#content").focus();
}
});
}
return false;
});
});
</script>
I have my $_POST as follows in action_comment.php
echo $me = $_POST['me'];
//DATASTRING FROM TEXTAREA
echo $content= $_POST['content'];
var dataString = 'content='+ textcontent;
$.ajax({
type: "POST",
url: "actions/action_comment.php",
data: {name: info, me: '<?php echo $me; ?>',txt_data: dataString},
....
});
Cannot use data attribute multiple times in same ajax request. Within php file you can access like $_POST['txt_data'] to get textarea content and same way for other parameters;
define data attribute once and pass all the data like as shown above.
if you want to post whole form data you can use this way
var form = $('#my_form');
$.ajax( {
type: "POST",
url: form.attr( 'action' ),
data: form.serialize(),
..
..
});
I'm trying to pass a long Html string from a view to a controller using an ajax call, so I can pass it further to another view.
Markup:
<a id="openPDF">Save as PDF</a>
JS:
$('#openPDF').click(function(){
var htmlText = $( "div.modal" ).html(); //grab the html
var dataToSend = JSON.stringify("{strData : '" + htmlText + "' }");
console.log(dataToSend ); // contains the json
$.ajax({
url: "/dashboard/pdf",
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: dataToSend
success: function (msg) { alert(msg.d); },
error: function (type) { alert("ERROR!" + type.responseText); }
});
});
Controller:
public function pdf(){
$data['htmlString'] = json_decode($this->input->post('strData'));
$this->load->view('pdf', $data);
}
My ajax call doesn't work because when a click the #openPDF button i get the alert error:
ERROR! NULL
What am I doing wrong?
Are you setting your headers properly before writing the output?
Controller:
public function pdf() {
$data['htmlString'] = json_decode($this->input->post('strData'));
$viewString = $this->load->view('pdf', $data, true); // this returns view as string rather than outputting it
header('Content-Type: application/json');
echo json_encode(['viewString' => $viewString]);
}
In client-side js, you can pass this success function to $.ajax()
success: function (response) {
if ('undefined' !== typeof response.viewString) {
// append view to concerned element
$('#viewTarget').append(response.viewString);
} else {
console.log('response did not contain viewString');
}
},
I hope this helps.
Also:
Navigate directly to the url (the one you are sending an ajax request for) in your browser and see if you get a valid json output.
