I have an HTML form which i populate from a database. On submit we load a page called "viewgame.php". Now what i want is here to run some scripts to populate some tables with data but how exactly can i pass the variable which i got from the form ex. $_POST['gameNo'] to the other php file though JavaScript?
Below is some of my code
JS function
function refreshGameinfo() {
var load = $.get('gameinfo_sc.php');
$(".gameinfo").html('Refreshing');
load.error(function() {
console.log("Mlkia kaneis");
$(".gameinfo").html('failed to load');
// do something here if request failed
});
load.success(function(res) {
console.log("Success");
$(".gameinfo").html(res);
});
load.done(function() {
console.log("Completed");
});
}
How can i pass the $POST_['gameNo'] to the gameinfo_sc.php file so that i can get the correct results?
Try this
var load = $.get('gameinfo_sc.php',{gameNo:"1212"});
In your php file you can access it using
$_GET['gameNo']
For post method use
var load = $.post('gameinfo_sc.php',{gameNo:"1212"});
In your php file you can access it using
$_POST['gameNo']
You are trying to post $POST_['gameNo'] to gameinfo_sc.php but $.get isn't the right method for post, its actually for http get. you can also do this by using $.post http://api.jquery.com/jquery.post/
function refreshGameinfo() {
$.ajax({
type: "POST",
url: "gameinfo_sc.php",
data: {gameNo: data},
cache: false,
success: function(html){
console.log( "Success" );
$(".gameinfo").html(res);
},
error:function(html){
console.log("Mlkia kaneis");
$(".gameinfo").html('failed to load');
}
});
}
try this
You can do it like this:
(in html layout):
<input type="hidden" id="gameNo" value="<?=$_POST['gameNo']?>" />
(in js file):
var gameNo = $('#gameNo').val();
var load = $.get('gameinfo_sc.php', {gameNo: gameNo});
....
UPDATE:
If your server doesn't support short open tags, you can write:
<input type="hidden" id="gameNo" value="<?php echo $_POST['gameNo'] ?>" />

When I click a button:
I need the JavaScript to perform some function.
Also run PHP code as well.
How can we achieve this?
PHP is only run by the server and responds to requests like clicking on a link/button (GET) or submitting a form (POST).
HTML & JavaScript is only run in someone's browser.
<html>
<?php
function PhpFunction() {
echo 'A php function';
}
if (isset($_GET['JsFunction'])) {
PhpFunction();
}
?>
Hello there!
<a href='index.php?JsFunction=true'>Run PHP Function On Click Of This Link</a>
</html>
Alternatively ,
You can create a ajax request to run a php code in your server..
Ajax can help you to send an asynchronous request to the server that php (or other) can catch, in this way you can implement and play with some callback functions
$.ajax({
url : "yourScript.php", // the resource where youre request will go throw
type : "POST", // HTTP verb
data : { action: 'myActionToGetHits', param2 : myVar2 },
dataType: "json",
success : function (response) {
//in your case, you should return from the php method some fomated data that you //need throw the data var object in param
data = toJson(response) // optional
//heres your code
},
error : //some code,
complete : //...
});
in your php script, you'll receive the request posted throw the superglobal vars like POST (for this example)
<?php
$action = (string)$_POST['action']; //this is unsecure, its just for the example
if("myActionToGetHits" == $action) {
//here you have to call your php function and so on..
$data = hitsMonth();
echo $data;
exit;
}
here is html
<a href="#" onclick="javascript:functionName(arg1, arg2);">
This is a basic example to do it, there are lots of ways to do.
Have javascript do the submit:
function button1() {
// js code here
var formelt = document.getElementById("form1");
formelt.submit(); // this will submit the form to server
}
Example =>
<button class="btn-test">Btn Test</button>
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script>
jQuery('.btn-test').click(function() {
js_do_something();
php_do_something();
});
function js_do_something() {
console.log('something done from js');
}
function php_do_something() {
console.log('something done from php');
jQuery.ajax({
type: "POST",
url: 'you_php_file.php',
data: {param: 'btn-test-click'},
success: function () {
console.log('success');
}
});
}
</script>
There you have how to execute a php function with on Onclick.
Execute PHP function with onClick
You can execute a Javascript function assuming you´re using jQuery like this:
jQuery('#id-button').on('click', function(){
// your function body
});
I'm trying to do an Ajax call on button click to insert to a database through a PHP file. I want to use AJAX to achieve this, but it does not show the alert dialog on success nor does it insert the data to the database. Here is the code I have:
AjaxTest.html:
<button type="button" onclick="create()">Click me</button>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js">
function create () {
$.ajax({
url: "AjaxTestRegistration.php",
type: "POST",
data: {
'bid': 10,
'kid': 20
},
success: function (msg) {
alert("!");
}
});
}
</script>
AjaxTestRegistration.php:
<?php
include "connection.php";
include "Coupon.php";
$bid = $_GET['bid'];
$kid = $_GET['kid'];
Coupon::insertCoupon($bid, $kid);
?>
If I try to enter AjaxTestRegistration.php manually in the browser like this: ajaxtestregistration.php?kid=10&bid=5, the row gets inserted into the database.
wWhat could be the problem with this code? How to rectify that?
Your PHP handles GET requests.
$bid = $_GET['bid'];
But your ajax function tries to POST
type: "POST",
The easiest here is to get your data by $_POST in php.
I think you should try $__REQUEST method of php and also use $_POST method if you use post from ajax
$bid = $__REQUEST['bid'];
$kid = $__REQUEST['kid'];
I am new to code, and trying to learn things by doing them.
Currently, I am trying to do something very simple using wordpress. which I am trying to create some posts in wordpress, using some external data.
I can fetch the data using CURL. No problem with that and post it using Wp_insert_post, directly.
But, What I want to do is trigger the wp_insert_post function on click of a button in the admin panel ( I have created this as a plugin and a separate plugin dashboard, where the button Is embedded). I have been messing around with the code, and sending the data to wp-admin-ajax.php work fine, and gives the response code 200. But, the response receiving is "0" . if the data passed through are correct, I presume, the response should be "1" ?
I have the following code at the moment.
//Button
<form id="formtesting">
<input type="text" id="name" placeholder="Name">
<input type="submit" id="user-submit" value="user-submit">
//Ajax Call
$(document).ready(function() {
var userSubmitButton = document.getElementById('user-submit');
var adminAjaxRequest = function(formData, myaction) {
$.ajax({
type: 'POST',
dataType: 'json',
url: '/wpdevelopment/wp-admin/admin-ajax.php',
data: {
action: myaction,
data: formData
},
success: function(response) {
if (true === response.success) {
alert('success');
} else {
alert(response);
}
}
});
};
userSubmitButton.addEventListener('click', function(event) {
event.preventDefault();
var formData = {
'name': document.getElementById('name').value
};
adminAjaxRequest(formData, 'data_submission');
});
});
And here is my test function // to test whether the function initiate properly, i try to send a Json error, So then I can include wp_insert_post details.
function data_submission(){
wp_send_json_error( 'I am an error' );}
add_action( 'wp_ajax_data_submission', 'data_submission' );
add_action( 'wp_ajax_nopriv_data_submission', 'data_submission' );
Could not locate where the faulty is. Some help would be appriciated
tks
Use add_action(' wp_ajax_myaction', 'yours_callback_fanc');
wp_ajax_
Remain part is yours action name that is defined into yours ajax call. In yours case it's myaction.
First this is not a standard way to use ajax in wordpress,
use wp_localize_script for embedding the global ajax_url variable,
wp_register_script('plugin-ajaxJs', plugins_url('/js/ajax-call.js', __FILE__));
wp_enqueue_script('plugin-ajaxJs');
wp_localize_script('plugin-ajaxJs', 'my_ajax_url', array('ajax_url' => admin_url('admin-ajax.php')));
Now as url in ajax you can add my_ajax_url.ajax_url,
this will send a request to admin-ajax.php.
Now coming to your question
you are returning an wp_json_error so the result is 0,
use this and return whatever data you wants in ajax success,
$responce['result'] = 1
wp_send_json( $response );
JavaScript
function calcPrimesLoop() {
var primes = document.getElementById('primes');
primes.appendChild(document.createTextNode('\n'+this.prime.nextPrime()));
$.ajax({
url: "/test.php",
type: "post",
data: {prime: this.prime.nextPrime()},
success: function(data) {
}
});
calcPrimesDelay = setTimeout('calcPrimesLoop()', this.delay);
}
Php
<?php
$content = $_POST['prime'];
$fn = "content.txt";
$content = stripslashes('prime'"\n");
$fp = fopen($fn,"a+") or die ("Error opening file in write mode!");
fputs($fp,$content);
fclose($fp) or die ("Error closing file!");
?>
So this is all the relevant scripting I think. I have a script that can get prime numbers and it works perfectly. But now I want to record these numbers on a text file. This is how I am trying to do it but I am having no success at all. Thank you. The issue is the numbers aren't being recorded.
I added an alert the Ajax is working. But when I add a form to the php script and submit it that works. So the ajax and php scripts are not working together as such.
You should read up about AJAX and see how you can pass information to a serverside page using Javascript and retrieve the return value.
http://www.w3schools.com/ajax/default.asp
https://www.youtube.com/watch?v=qqRiDlm-SnY
With ajax and jQuery it is actually simple.
function calcPrimesLoop() {
var primes = document.getElementById('primes');
primes.appendChild(document.createTextNode('\n'+this.prime.nextPrime()));
$.ajax({
url: "myScript.php", // URL of your php script
type: "post",
data: {prime: this.prime.nextPrime()},
success: function(data) {
alert("success");
}
});
calcPrimesDelay = setTimeout('calcPrimesLoop()', this.delay);
}
myScript.php :
<?php
$content = $_POST['prime'];
...
You should definately look for Asynchronous JavaScript and XML.
You can choose between using AJAX with a Javascript function, or simplify your life with jQuery
Here is a sample:
//STEP ONE: INCLUDE THE LAST VERSION OF JQUERY
<script src="http://code.jquery.com/jquery-latest.min.js"
type="text/javascript"></script>
//STEP TWO, GET YOUR FUNCTION TO WORK:
function sendVariableTo(variable,url) {
$.ajax({
url:url, //Or whatever.php
type: "GET", //OR POST
data: { myVar: variable}, //On php page, get it like $_REQUEST['myVar'];
success:function(result){
//If the request was ok, then...
alert(result) //Result variable is the php page
//output (If you echo "hello" this alert would give you hello..)
},
});
}
Hope this helped, bye !
When a form sends variable with GET Method, the URL changes, putting the variables that you are passing in this way
url?variable=....
How can I get the same result with jQuery Ajax? Is it possible? Thank you
set path in your php layout/view file where you include this code
<script>
var path="<?php echo $this->webroot;?>";
</script>
and add following jquery code to post the data through ajax.
$.ajax({
type: 'POST',
url: path+'homes/createEvent',
data: {eventname:eventname,manager:manager},
async: false,
success: function(resulthtml)
{
alert(resulthtml);
},
error: function(message)
{
alert('error');
}
});
and on homes_controller.php, u will get this ajax data in createEvent function,
<?php
function createEvent()
{
$eventName=$_POST['eventname'];
$manager=$_POST['manager'];
}
?>
