Hi I'm trying to pass a php variable from produto.php to another file descProduto.php it ajax but without success. Please someone can tell me what I'm doing wrong? The ajax is working but I can't get the value on descProduto.php
This is where I click produto.php
<img class="btn-details" src="plus.png" data-idproduto="'.$idproduto.'"/>
My ajax ( diferent file ajax.js)
$(function(){
$(".btn-details").on('click', function(){
var idproduto = $(this).data('idproduto');
$.ajax({
type: "POST",
url: "descProduto.php",
async: false,
dataType: "html",
data: {'idproduto': idproduto},
success: function(result){
console.log("success");
},
error: function(){
console.log("error");
}
});
return false;
});
});
Where I get the variable descProduto.php
if(isset($_POST['idproduto'])){
$idproduto = $_POST['idproduto'];
echo $idproduto;
}
Thanks
Why using AJAX ? .You can't use for this matter.just use session
In page1.php
<?php
session_start();
$_SESSION['var'] = 'foo'
In Page2.php
echo $_SESSION['var']; //foo
First of all check whether your $idproduto actually prints on produto.php (Developer Tools/ FireBug/ View Source).
Then console.log(idproduto) before sending the ajax post to see whether it sets correctly.

I need to have a "global" variable because I need to use it in different page and I want to modify it too: I think that I need to use $_SESSION
I need to change this variable, when the user click on dropdown or list.
I have this:
SOLUTION 1
PageA:
$('#list.test li').on('click',function(){
choice=$(this).attr('id');
$.ajax({
url: "PageB.php",
data: {word : choice},
dataType: "html",
success: function (data) {
$('#content_table').html(data);
}
});
});
PageB
session_start();
$_SESSION['b']=$_GET['word'];
echo $_SESSION['b']; // It works
PageC for verify the result
session_start();
echo $_SESSION['b']; // Error !!
In my PageC, I have an error ( Notice: Undefined index: b )
Is it possible to update session variable with ajax ?
SOLUTION 2
PageA: I want to passe the id JS var to PHP var
$('#list.test li').on('click',function(){
choice=$(this).attr('id');
<?php $_SESSION['b'] ?> = choice; //<--- it is possible ?
$.ajax({
url: "PageB.php",
data: {word : choice},
dataType: "html",
success: function (data) {
$('#content_table').html(data);
}
});
});
This solution doesn't work because AJAX and PHP are note in the same side (client/server).
Thank you
You can push data to cookies via JavaScript, smth like document.cookie = "key=value";
And receive it on back-end like $_COOKIE["key"];.
$_SESSION['b']=$_GET['projet']; should be $_SESSION['b']=$_GET['word'];
I am using an ajax call to save value of a radio button through hidden field in database using ajax call, used an alert to see if its working, and it is.
The URL I mentioned in the ajax call is redirecting it to a controller but I used an alert to see if its working, but its not working. Can't locate what's the issue.
Here is the code of ajax call in view:
<script type="text/javascript">
$('#save').click(function(){
var hint=$('#hidfield').val();
alert('Oops, your response is '+hint);
$.ajax({
url: '<?php echo base_url();?>welcome/save_answer',
type: "post",
dataType: "html",
data:{hint:$hint, <?php echo $this->security->get_csrf_token_name();?>: "<?php echo $this->security->get_csrf_hash();?>"},
success: function(data) {
}
});
});
</script>
Here is the controller:
function save_answer()
{
alert('You Can Do It !!');
$data = array(
'hint'=>$this->input->post('hint')
);
$this->base_model->save_answer($data);
}
Here is the model:
function save_answer($data)
{
$this->db->insert('questions',$data);
}
Please suggest some way out.
You cannot used javascript "alert()" inside controller.
instead of "alert('You Can Do It !!');" use "die('You Can Do It !!');" to debug, and check in to your console.
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.

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 !
So guys, I made a listbox and if I dblclick to an item the value of it gets saved into "val", but I can't send it to the next PHP File. I also alerted "val" - the value is really saved in it. I also get the function succes displayed in the browser console. what to do?
thanks
My Function:
$(document).ready(function () {
$("option").dblclick(function () {
var lb = document.getElementById("liste");
var val = lb[lb.selectedIndex].value;
$.ajax({
type: 'POST',
url: 'about.php',
dataType: 'HTML',
data: {
aufid: val
},
success: function (data) {}
});
});
});
PHP Code in about.php:
$id = $_POST['aufid'];
Can you try to see what variables are in the $_POST superglobal?
print_r($_POST);
try to set the url your full adrees
url: 'http://myadress.com/about.php',
java script is running on your local computer so it might send the request to you own pc where no about.php exist
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'];
}
?>
