So, I am stuck here and feel like banging my head.
My problem is I query a database by ajax and returned its response in json form. Now I have this response in the form of javascript variable but I want to pass it to a php variable for further use.
How can I do that ??
function getJson(url){
return JSON.parse($.ajax({
type:'GET',
url: url,
dataType:'json',
global:false,
async:false,
success: function(data){
return data;
}
}).responseText);
}
Here how do I pass data to php ??
FIrstly I gave you -1 for not learning the basics!
- You can send client values to server (php) as querystring
example: /server_link?json=JSON_VAL
(not recommended for whole json string)
- Send it as post body (look for jquery ajax post) and parse it with php json library.
- if you have just single level json ({name:'John', sname:'Smith)} you can send it to php server(as mentioned before ajax post) and read as request variable in php ($_POST, $_...).
As I never programmed in php you'll have to do it you're self.
A again: LEARN THE BASICS (client side, server side, post, get,...).

I have a node.js server running and is executing what I want it to do, create an excel document with data fetched with Axios from an API, now, I want to allow a user to input a string on my HTML and then send that string to my web server, and perform an Axios request to the API that I am consuming. How can I do that? Should I use a POST request, a PUT request, or anything else?
Thanks!
You should be able to send data from your client to the server via the request body regardless of the request method whether GET/POST/PUT.
fetch call would look like this
// just a simple get request
fetch('/example-endpoint', {
method: 'POST',
body: {
data: 'String to be sent'
}
});
And on your node express server
app.post('/example-endpoint', (req, res) => {
const data = req.body.data;
// do stuff with your data here.
})
GET request method is used for getting data, while POST and PUT are used for creating and updating data, so use them as you need them.
POST request to your server, like uh https://myserver.com/api/${userString}
something like that
I am trying to load some images from a file on a server to display on a list. I get 404 not found error
after asking in forums, I get that the request URL is wrong, it looks inside the localhost not inside the json file.
https://filehost.net/db54d37849f75ddd
in the code I have a service which returns a response. I use that response in a controller and to the view. I get other information but no images
if anybody has a solution that would be really great.
please attach also some code, in this way it is easier to help you. About the problem, do have correct form of $http GET request? I mean does your get request points to correct address on server? something like this
`
// Simple GET request example:
$http({
method: 'GET',
url: '/someUrl'
}).then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});

Problem is when i try to use this code to get the log from tmi.twitch.tv api using url: http://tmi.twitch.tv/hosts?include_logins=1&target=70219146 i get Systax Error Unexpected Token. The code is:
$(document).ready(function() {
$.getJSON("http://tmi.twitch.tv/hosts?include_logins=1&target=70219146&callback=?", function (data) {
console.log(data.hosts)
});
})
I can get the data using php and json array like this:
$json_array = json_decode(file_get_contents('http://tmi.twitch.tv/hosts?include_logins=1&target=70219146'), true);
echo $json_array['hosts']['0']['host_login']."</br>";
But isnt there a way to use do this in html? thanks
You are trying to request regular JSON as JSONp (&callback=? activates jQuery's JSONp request method) which actually embeds the response into a <script> to execute it. However, the twitch API still returns JSON which is not valid JavaScript. Unless there is a way to make tmi.twitch.tv return valid JSONp, there is no way to do this directly from JavaScript unless you use a proxy like http://crossorigin.me/.
I am creating an application using Durandal, with WebAPI as the server. I have a KendoUI grid that displays the data from the server correctly and functions properly until the POST or PUT methods are called. Here is my GET method:
and you can see that that data binds to the UI (used the data-bind extensibility in Durandal to change to kendo bindings):
Then I edit the data in the Grid and it passes the changes inside the request to the server as you can see in this Fiddler result:
On the server side I cannot get the data that is passed from the client to bind to anything I place as a parameter for the method on the POST or PUT.
I realize this is a couple different technologies to troubleshoot (e.g. Durandal, KnockoutJs, Kendo DataBinding, and WebAPI) but I think the fundamentals are working, the data is retrieved and bound to the UI and it is posted back when changed, but the WebAPI endpoint cannot bind to the data.
How can I get the passed "models" array to bind through the ModelBinding structure in WebAPI?
UPDATE- Here is the helpful JSFiddle that gave me the correct Content-Type to add: http://jsfiddle.net/Xhrrj/1/
new kendo.data.DataSource({
transport: {
read: {
type: "POST",
url: "../cccs/service.svc/SupplierSearch",
contentType: "application/json; charset=utf-8",
dataType: 'json'...
this is coming from the Telerik forum here
It looks as if it was mixing up form-urlencoded with json format - if you lookat the decoded string it is sending models= and then urlencoded JSON objects follow.
From my experience I think that your PUT end point declaration needs to look like this:
[HttpPut]
public void Put([FromBody]IEnumerable<Product> models) { }
So you need the FromBody attribute because your product array is in the body (I think?) and not in the url of the request.
I am using jQuery to post JSON data to a tomcat server and the server is handling the JSON array data perfectly! It is as though I passed key=value request parameters along with the URL.
So why am I posting this? I would like to know how the server treats JSON in the body of a request and how the data ends up being interpreted as request parameters. I have Googled my a** off and all I find is how the server sends JSON back to the client.
$.ajax() converts JSON data into key-value pairs (querystring style) by default. You need to set { processData : false } in the AJAX request to keep it as raw JSON.
