I'm practicing with the PHP RestServer Class. But I can't get the correct data from it if I use an Ajax call on it. I have the following code:
<?php
require_once "locationOfRestServer.php";
class HelloWorld
{
public static function sayHello()
{
return array("Response" => "Hello World");
}
}
$rest = new RestServer('HelloWorld');
$rest->handle();
And in my javascript file I use the following:
this.helloWorld = function() {
$.ajax({
url: 'locationOfHelloWorld.php'
type: 'POST',
dataType: 'json',
success: function(data){
console.log(data);
}
});
};
I get the following error:
error: "No method was requested."
Because; whenever I use it, I have to go to localhost/HelloWorld.php?method=sayHello which is actually working.
So I added the following line to the ajax call:
method: 'sayHello',
But it still keeps giving me the same error.
Try this,
$.ajax({
url: 'locationOfHelloWorld.php'
type: 'GET',// use GET method according to your working url
data:{method: 'sayHello'},// use method in data parameter
dataType: 'json',
success: function(data){
console.log(data);
}
});

I want to alert the return value from a php method, but nothing happens. Here is the ajax and php methods. Can anyone see what I am doing wrong?
--------------------------------------…
Ajax script
$.ajax({
type: 'get',
url: '/donation/junk/4',
data: datastring,
success: function(data) {
alert(data');
}
});
--------------------------------------…
php method
function junk($id)
{
return "works11";
}
in PHP, you can't simply return your value and have it show up in the ajax response. you need to print or echo your final values. (there are other ways too, but that's getting off topic).
also, you have a trailing apostrophe in your alert() call that will cause an error and should be removed.
Fixed:
$.ajax({
type: 'get',
url: '/donation/junk/4',
data: datastring,
success: function(data) {
alert(data);
}
});
PHP:
function junk($id)
{
print "works11";
}
You have an extra ' in there on the alert(data') line
This should work
$.ajax({
type: 'get',
url: '/donation/junk/4',
data: datastring,
success: function(data) {
alert(data);
}
});
And your PHP code should call the method also and echo the value
function junk($id) {
return 'works11';
}
exit(junk(4));
All you're doing currently is creating the method
ajax returns text, it does not communicate with php via methods. It requests a php page and the return of the ajax request is whatever the we babe would have showed if opened in a browser.
Hi I am currently learning php and I am trying to get data from php file using the below script but i am not getting any response
$.ajax({
type: 'POST',
url: "mark_mod.php",
data: data_set,
dataType: "JSON",
success: function(data) {
alert("Response : " ); // not triggering
}
});
my php return stmt
There might be problems with File URL or file access. You can use complete callback to check request for errors like that:
$.ajax({
type: 'POST',
url: "mark_mod.php",
data: data_set,
dataType: "JSON",
success: function(data) {
alert("Response : " );
},
// This method will be fired when request completes
complete: function(xxhr, status) {
alert("Status code: " + status);
}
});
If the status code is not success that means there is something wrong with your request.
You can check more callback options here.
It doesn't matter whether you use return or echo in your PHP file.
The success method must get a call if it's fine. However, if you use
return instead of echo, nothing will append to your request's data.
On the other hand, The PHP response will include in your 'data' variable in the function success.
You need use data in the assync function success
success: function(data) {
alert("Response : " + data);
},
Thanks for your Responses. I got the Solution to my problem. It seems since Ajax is asynchronous... its taking time to receive the resultant echo value from my php file. so I had to synchronize my Jquery using async : False.
$(function(){
$('#formID').on('submit',function(){
const data_set={
name:"Nipu chakraborty",
"phone":"01783837xxx"
}
$.ajax({
type: 'POST',
url: "mark_mod.php",
data: data_set,
dataType: "JSON",
success: function(data) {
alert(data);
}
});
});
});
I am using this javascript function to send data to my php script (via POST) I am then using this information to retrieve data from my database and I would like to reuse the information retrieved in my JavaScript code.
Here is my code :
$(document).on("click", "#validerChoixDeCours", function() {
jQuery.ajax({
type: "POST",
url: 'myFunctions.php',
dataType: 'json',
data: {
functionname: 'proposePA',
arguments: clickedButtons
},
success: function() {
// HERE I would like to inctercept the data that my php script put in myFunctions.php produces and use it to generate content;
}
});
});
So basically, when clicking on the button #validerChoixDeCours, my code sends some data to myFunctions.php which generates a response stored in a php variable and I want to use that response in my JS code.
Thank you in advance for your help :)
Its actually quite easy!
$(document).on("click", "#validerChoixDeCours", function() {
jQuery.ajax({
type: "POST",
url: 'myFunctions.php',
dataType: 'json',
data: {
functionname: 'proposePA',
arguments: clickedButtons
},
success: function(e) {
e contains the response from the php script
}
});
});
The first parameter of success contains the response from the request. so, in this case, the 'e' variable contains the output which you can use.
Add data variable
$(document).on("click", "#validerChoixDeCours", function() {
jQuery.ajax({
type: "POST",
url: 'myFunctions.php',
dataType: 'json',
data: {
functionname: 'proposePA',
arguments: clickedButtons
},
success: function(data) {
alert(data);
}
});
});
make sure your server side code look like this
<?php
$output = "Any String or Array";
echo json_encode($output);
?>
Im using Yii framework, i want to call controller function from JS file,
My ajax code in JS file:
$.ajax({
type: "POST",
url: "operator/checkDisabledDates",
data: {
id: 1
},
success: function(data) {
alert('success');
},
error: function(data) {
alert("Fail");
}
});
where checkDisabledDates is my controller method name, and operator is my controller name.
i got wrong formation of url something like,
www.example.com/operator/agent/id/4/operator/checkDisabledDates
my ajax url just appends at last position of existing url,
i tried different combinations like,
url: "/operator/checkDisabledDates"
url: "../operator/checkDisabledDates"
url: "../checkDisabledDates"
nothing worked,
but when i use in below syntax it worked,
url: "../../checkDisabledDates"
Is there anyway to do this without hardcoding dots(.) like this???
I would suggest not using a relative path to call your controller.
Try using your domain as context
var domainName = 'yourSite.com'
url: domainName+"operator/checkDisabledDates"
I'm using in my project and it's working for me, please try this -
Define a Global Variable in JS file eg. -
var url_path = document.location.origin+document.location.pathname;
so now you can use like this
url: url_path+'?r=operator/checkDisabledDates'
or
url: url_path+'operator/checkDisabledDates'
Use this:
data = {};
data.r = 'operator/checkDisabledDates';
data.id = 1;
$.ajax({
type: "POST",
url: "index.php",
data: data,
success: function(data) {
alert('success');
},
error: function(data) {
alert("Fail");
}
});
Always works for me.
I'm sending from view using jQuery to MVC post action
function DoSomething(passedId) {
$.ajax({
method: "POST",
dataType: 'text',
url: '/MyController/SomeAction/',
data: { id: passedId}
}).done(function (data) {
//
});
}
And inside MyController
[HttpPost]
public ActionResult SomeAction(int id)
{
...
}
In Firebug console I'm getting 404 error.
You didn't said which version of jquery you are using. Please check jquery version and in case that this version is < 1.9.0 you should instead of
method: "POST"
use
type: "POST"
this is an alias for method, and according to jquery official documentation you should use type if you're using versions of jQuery prior to 1.9.0.
function DoSomething(passedId) {
$.ajax({
type: "POST",
dataType: 'text',
url: '/MyController/SomeAction/',
data: { id: passedId}
}).done(function (data) {
...
});
}
Tested above code and it works (each request enter inside mvc controller http post SomeAction action).
In the RFC 2616 the code 404 indicates that the server has not found anything matching the Request-URI.
So you need to look at your URL parameter.
Try the MVC conventional call using :
url: '#Url.Action("SomeAction", "MyController")',
To resolve the 404 issue:
There are a few options to resolve this. You controller/action cannot be find the way it is describe.
-If you are in a view that is in the controller for which the action your are trying to call is located, then:
url: 'SomeAction',
-If you are trying to call an action from another controller, OtherController, for example, then:
url: 'Other/SomeAction',
-To add to another answer, if you are calling your ajax inside the view (and NOT in a javascript file) then you can also use (for a controller called SomeController):
url: '#Url.Action("SomeAction", "Some")',
Additional Items Of Note:
You do not specify a content type for json (contentType indicates what you are sending):
contentType: "application/json; charset=utf-8",
I can't tell, based on your action if you are expecting 'text' or something else. However, unless expecting 'json', I would remove the data part.
You need to stringify your data
JSON.stringify(data: { id: passedId}),
In the end, I would expect it to look something like:
function DoSomething(passedId) {
var url = "SomeAction"; //if action is in OtherController then: "Other/SomeAction"
$.ajax({
method: "POST",
url: url,
data: JSON.stringify({ id: passedId}),
contentType: "application/json; charset=utf-8"
}).done(function (data) {
//
});
}
The slash at the beginning of this designates an absolute path, not a relative one.
/MyController/SomeAction/
You should include a URL or relative path.. maybe
'MyController/SomeAction/ajax.php'
or the full URL
'http://example.com/myajaxcontroller/someaction/ajax.php'
or stolen from the other guys answer
url: '#Url.Action("SomeAction", "MyController")',
To address others on here, I don't think the datatype is the
problem... OP says "I'm getting 404 error."
contentType is the type of data you're sending, so
application/json; charset=utf-8 is a common one, as is
application/x-www-form-urlencoded; charset=UTF-8, which is the
default.
dataType is what you're expecting back from the server: json, html,
text, etc. jQuery will use this to figure out how to populate the success function's parameter.
Write the code this way:
function DoSomething(passedId) {
$.ajax({
url: 'yourController/SomeAction',
type: 'POST',
data: { id: passedId},
dataType: 'json',
error: function (ex) {alert(ex.responseText)},
success: function (data)
{
if (data.Results != null) {
//use the return values
});
}
}
});
}
and the controller
public JsonResult SomeAction(int id)
{
try
{
return Json(new { Results = "Text To return or send some object or an list, etc"}, JsonRequestBehavior.AllowGet);
}
catch (Exception)
{
throw;
}
}
Finally, check that the controller has its respective view. :)
and and the library of "jQuery" updated.
just in case.
use the following ajax call
var datum = { id: passedId };
$.ajax({
url: url, // your url
type: 'POST',
data: JSON.stringify(datum),
contentType: 'application/json; charset=utf-8',
beforeSend: function () {
},
complete: function () {
},
success: function (user, status, XHR) {
},
error: function (req, status, error) {
}
});
UpDated
public ActionResult SomeAction(int id){} should accept string parameter instead of int
