Good day, I am new to AJAX. I'm trying to get a data from a function inside a class using a handler but when I include the class file the output becomes a bunch of html instead of the actual echoed string.
JS
$('#login-btn').on('click', function () {
var username = $('#username').val();
$.post("./php/functions/loginHandler.php",
{
usernameInput: username
}, function (data) {
console.log(data);
});
});
PHP Handler
<?php
include_once './php/database/DBOperations.php';
if (isset($_POST['usernameInput'])) {
echo 'test';
}
Thank you, have a good day.
Please use this ajax code, maybe working :
$('#login-btn').on('click', function () {
var username = $('#username').val();
$.ajax({
type: "POST",
url: 'your url',
data: username,
success: function(response)
{
console.log(response)
}
});
});
warning : you must add jquery in your html file

How can I load data from my PHP response via ajax into a panel?
My PHP outputs correctly and I can see a table in the response, but I can;t get it to build the data on my webpage.
Here is my jquery/ajax so far. It passed the value to PHP correctly and PHP builds the table via its echo, but what am I missing for AJAX to display the table?
PHP:
<?php
foreach ($lines as $value) {
echo "<input name='data[]' value='$value'><br/>";
}
?>
JQUERY:
$(function () {
$('#rotator').change(function (e) {
var rotator = $("#rotator").val();
$.ajax({
type: "POST",
url: "tmp/JFM/National/national.php",
data: {
rotator: rotator
},
success: function (result) {
$('#panel').load(result);
}
})
return false;
});
});
The answer to this was two fold.
I was attempting to append to my main div, which apparently can't happen. I created a new empty div and was able to load the results there.
Beyond that, the comments to change .load(results) to .html(results) were needed.
The correct jquery code is below.
$(function () {
$('#rotator').change(function (e) {
var rotator = $("#rotator").val();
$.ajax({
type: "POST",
url: "tmp/JFM/National/national.php",
data: {
rotator: rotator
},
success: function (result) {
console.log(result);
$('#test').html(result);
}
})
return false;
});
});
move your function from:
$.ajax({...,success: function(){...}});
to
$.ajax({..}).done(function(){...});
if it doesn't work, try to add async:false into the ajax object...
$.ajax({...,async:false}).done(function(){...});
Hope it helps... =}
I've tried to go to php file using jquery.
Here is my code.
This is index.php
$.post('test.php',data,function(json){},'json');
This is test.php
//set session variable from passed data
$_SESSION['data1'] = $_POST['data1'];
<script>
window.open('test1.php','_blank');
</script>
This is test1.php
echo $_SESSION['data1'];
But this code is not working.
I want to pass data from index.php to test1.php.
How can I do this? I don't want to use GET method because of too long url.
Anyhelp would be appreciate.
I am not quite clear from you explanation right now. But I am here trying to resolve you problem as you can use the jquery post method as follows :
$.post('test1.php',{param1:value1,param2=value2,...},function(data){
//Here you can take action as per data return from the page or can add simple action like redirecting or other
});
Here is a simple example of register :
$.post('', $("#register_form").serialize(), function(data) {
if (data === '1') {
bootbox.alert("You have registered successfully.", function() {
document.location.href = base_url + '';
});
} else if (data === '0') {
bootbox.alert("Error submitting records");
} else {
bootbox.alert(data);
}
$("#user_register_button").button("reset");
});
Try this:
$.ajax({
url: 'test.php',
type: 'POST',
data: {
myData : 'somevalue'
},
success: function(response){ // response from test.php
// do your stuff here
}
});
test.php
$myData = $_REQUEST['myData'];
// do your stuff here
I like use jQuery post a url like this.
$('form').on('submit', function(e) {
e.preventDefault();
var $this = $(this);
$.ajax({
url: $this.attr('action'),
method: $this.attr('method'),
data: $this.serializeArray(),
success: function(response) {
console.log(response);
}
})
});

I have checked around, but can't seem to figure out how this is done.
I would like to send form data to PHP to have it processed and inserted into a database (this is working).
Then I would like to send a variable ($selected_moid) back from PHP to a JavaScript function (the same one if possible) so that it can be used again.
function submit_data() {
"use strict";
$.post('insert.php', $('#formName').formSerialize());
$.get('add_host.cgi?moid='.$selected_moid.');
}
Here is my latest attempt, but still getting errors:
PHP:
$get_moid = "
SELECT ID FROM nagios.view_all_monitored_objects
WHERE CoID='$company'
AND MoTypeID='$type'
AND MoName='$name'
AND DNS='$name.$selected_shortname.mon'
AND IP='$ip'
";
while($MonitoredObjectID = mysql_fetch_row($get_moid)){
//Sets MonitoredObjectID for added/edited device.
$Response = $MonitoredObjectID;
if ($logon_choice = '1') {
$Response = $Response'&'$logon_id;
$Response = $Response'&'$logon_pwd;
}
}
echo json_encode($response);
JS:
function submit_data(action, formName) {
"use strict";
$.ajax({
cache: false,
type: 'POST',
url: 'library/plugins/' + action + '.php',
data: $('#' + formName).serialize(),
success: function (response) {
// PROCESS DATA HERE
var resp = $.parseJSON(response);
$.get('/nagios/cgi-bin/add_host.cgi', {moid: resp });
alert('success!');
},
error: function (response) {
//PROCESS HERE FOR FAILURE
alert('failure 'response);
}
});
}
I am going out on a limb on this since your question is not 100% clear. First of all, Javascript AJAX calls are asynchronous, meaning both the $.get and $.post will be call almost simultaneously.
If you are trying to get the response from one and using it in a second call, then you need to nest them in the success function. Since you are using jQuery, take a look at their API to see the arguments your AJAX call can handle (http://api.jquery.com/jQuery.post/)
$.post('insert.php', $('#formName').formSerialize(),function(data){
$.get('add_host.cgi?moid='+data);
});
In your PHP script, after you have updated the database and everything, just echo the data want. Javascript will take the text and put it in the data variable in the success function.
You need to use a callback function to get the returned value.
function submit_data(action, formName) {
"use strict";
$.post('insert.php', $('#' + formName).formSerialize(), function (selected_moid) {
$.get('add_host.cgi', {moid: selected_moid });
});
}
$("ID OF THE SUBMIT BUTTON").click(function() {
$.ajax({
cache: false,
type: 'POST',
url: 'FILE IN HERE FOR PROCESSING',
data: $("ID HERE OF THE FORM").serialize(),
success: function(data) {
// PROCESS DATA HERE
},
error: function(data) {
//PROCESS HERE FOR FAILURE
}
});
return false; //This stops the Button from Actually Preforming
});
Now for the Php
<?php
start_session(); <-- This will make it share the same Session Princables
//error check and soforth use $_POST[] to get everything
$Response = array('success'=>true, 'VAR'=>'DATA'); <--- Success
$Response = array('success'=>false, 'VAR'=>'DATA'); <--- fails
echo json_encode($Response);
?>
I forgot to Mention, this is using JavaScript/jQuery, and ajax to do this.
Example of this as a Function
Var Form_Data = THIS IS THE DATA OF THE FORM;
function YOUR FUNCTION HERE(VARS HERE) {
$.ajax({
cache: false,
type: 'POST',
url: 'FILE IN HERE FOR PROCESSING',
data:Form_Data.serialize(),
success: function(data) {
// PROCESS DATA HERE
},
error: function(data) {
//PROCESS HERE FOR FAILURE
}
});
}
Now you could use this as the Button Click which would also function :3
Everything was going great in my previous help request thread. I was on the correct track to get around a CSRF, but needed to be pointed in the right direction. I received great help and even an alternate script used to log into Google's Android Market. Both my script and the one I altered to match my form is get hung up at the same point. Apparently cURL cannot process JS, is there any way to work around the form being submitted with submitForm() without changing the form?
Here is the code for the SubmitForm function
function submitForm(formObj, formMode) {
if (!formObj)
return false;
if (formObj.tagName != "FORM") {
if (!formObj.form)
return false;
formObj = formObj.form;
}
if (formObj.mode)
formObj.mode.value = formMode;
formObj.submit();
}
Here is the code for the submit button -
<a class="VertMenuItems" href="javascript: document.authform.submit();">Submit</a>
Here is a link to my last question in case more background information is needed.
PHP service...
<?php
// PHP service file
// Get all data coming in via GET or POST
$vars = $_GET + $_POST;
// Do something with the data coming in
?>
Javascript elsewhere...
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
function sendData(data)
{
var response;
$.ajax({
url: 'phpservice.php',
data: data,
type: 'POST',
dataType: 'json',
async: false,
success: function(response_from_service)
{
response = response_from_service;
},
error: function()
{
}
});
return response;
};
function getData(data)
{
var response;
$.ajax({
url: 'phpservice.php',
data: data,
type: 'GET',
dataType: 'json',
async: false,
success: function(response_from_service)
{
response = response_from_service;
},
error: function()
{
}
});
return response;
};
});
</script>
Is it possibe to simply load a php script with a url with js?
$(function() {
$('form').submit(function(e) {
e.preventDefault();
var title = $('#title:input').val();
var urlsStr = $("#links").val();
var urls = urlsStr.match(/\bhttps?:\/\/[^\s]+/gi);
var formData = {
"title": title,
"urls": urls
}
var jsonForm = JSON.stringify(formData);
$.ajax({
type: 'GET',
cache: false,
data: { jsonForm : jsonForm },
url: 'publishlinks/publish'
})
//load php script
});
});
Edit:
function index() {
$this->load->model('NewsFeed_model');
$data['queryMovies'] = $this->NewsFeed_model->getPublications();
$this->load->view('news_feed_view', $data);
}
simple
jQuery and:
<script>
$.get('myPHP.php', function(data) {});
</script>
Later edit:
for form use serialize:
<script>
$.post("myPHP.php", $("#myFormID").serialize());
</script>
like this ?
$.get('myPHP.php', function(data) {
$('.result').html(data);
alert('Load was performed.');
});
There are various ways to execute a server side page using jQuery. Every method has its own configuration and at the minimum you have to specify the url which you want to request.
$.ajax
$.ajax({
type: "Get",//Since you just have to request the page
url:"test.php",
data: {},//In case you want to provide the data along with the request
success: function(data){},//If you want to do something after the request is successfull
failure: function(){}, //If you want to do something if the request fails
});
$.get
$.get("test.php");//Simplest one if you just dont care whether the call went through or not
$.post
var data = {};
$.post("test.php", data, function(data){});
You can get the form data as a json object as below
var data = $("formSelector").searialize();//This you can pass along with your request
