var itemtotal = parseFloat(words[1]).toFixed(2.0)*qty;
$.ajax({
type: 'POST',
url: 'cartitem.php',
data: {itemtotal:itemtotal},
success: function(data){
alert(data);
}
I want to add the value from each AJAX call to a PHP array for later processing. How can I do that?
php :
if (isset($_POST['itemtotal']))
{
$array = [];
if (is_numeric($_POST['itemtotal'])) {
//you need to do some validation here its just an example
array_push($array, $_POST['itemtotal']);
}
}
hope it helps

my ajax is:
add = 'request';
full_val = 'barrack obama';
$.ajax({
url: 'plugins/add_friend.php',
data: full_val+'='+add,
success: function(data)
{
}
});
if the javascript variable value changes depending on the conditions, then how will i $_GET[] the variable full_val? I want it to be something like:
$_GET[full_val]
is there a way to pass the variables of javascript to php?
If you want the literal index full_val, then use it in the query string:
data: 'full_val='+add,
So that in PHP, you'd be able to use $_GET['full_val']
Alternatively, you could also put an object in that field:
data: {full_val: full_val, add: add},
Here is the description:
data
Type: PlainObject or String or Array
Data to be sent to the server. It is converted to a query string, if not already a string. It's appended to the url for GET-requests.
Your data just has the values and does not have the keys. See below for how to pass the keys and values.
add = 'request';
full_val = 'barrack obama';
$.ajax({
url: 'plugins/add_friend.php',
data: {full_val:full_val,add:add},
success: function(data)
{
}
});
In your PHP use $_GET['full_val'];
send your values with data parameter correctly and add type:get to define GET method
add = 'request';
full_val = 'barrack obama';
$.ajax({
type: "get",
url: 'plugins/add_friend.php',
data: {'full_val':full_val,'add':add},
success: function(data) {
}
});
Then you will get values on php :-
use $_GET['full_val'] rather $_GET[full_val]
Try Using this
add = 'request';
full_val = 'barrack obama';
$.ajax({
url: 'add.php',
data: 'full_val='+add,
success: function(data)
{
alert(data);
}
});
You can use the .get() method. The variables you can set using an object literal. For example:
$.get("/plugins/add_friend.php", {
add: "request",
full: "Barrack Obama"
}).done(function(data) {
console.log("Status:", data.status);
console.log("Received:", data.received);
});
And the PHP could be done something like this:
$add = filter_input(INPUT_GET, 'add', FILTER_SANITIZE_STRING);
$full = filter_input(INPUT_GET, 'full', FILTER_SANITIZE_STRING);
echo json_encode(array(
'status': 'OK',
'received': "{$add} and {$full}",
));
I have number of checkboxes on my page and I want to get those checkbox values in my database.
$('#assign_data').on("click",function()
{
var mandate_array = [];
var i= 0;
$('.assign_mandate:checked').each(function(){
mandate_array[i++] = $(this).val();
});
$.ajax
({
type: "POST",
url: BASE_URL+"mandate/assign_mandate.php",
data: "mandate_array="+mandate_array+"&role_id="+$('#role').val()+"&user_id="+$('#user').val(),
success: function(msg)
{
console.log(msg)
}
})
});
assign_mandate.php :
<?php
$mandate = explode(',',$_POST['mandate_array']);
// print_r($mandate); //it shows the data in array
count($mandate);exit; // it does not show the count in console
?>
When I print the array it show me the array data in console but when I try to echo the count of array it shows blank. Why ?
Thanks in advance
You have to echo the variable count value.
<?php
$mandate = explode(',',$_POST['mandate_array']);
// print_r($mandate); //it shows the data in array
echo count($mandate);exit; // it does not show the count in console
?>
Use JSON.stringify.
You would typically convert the array to a JSON string with JSON.stringify, then make an AJAX request to the server, receive the string parameter and json_decode it to get back an array in the PHP side.
$('#assign_data').on("click",function()
{
var mandate_array = [];
var i= 0;
$('.assign_mandate:checked').each(function(){
mandate_array[i++] = $(this).val();
});
$.ajax
({
type: "POST",
url: BASE_URL+"mandate/assign_mandate.php",
data: "mandate_array="+JSON.stringify(mandate_array)+"&role_id="+$('#role').val()+"&user_id="+$('#user').val(),
success: function(msg)
{
console.log(msg)
}
})
});
mandate_array is Array so you wont posted array data in query string, you should use JSON.stringfy() function to convert array/JSON object into string.
$.ajax
({
type: "POST",
url: BASE_URL+"mandate/assign_mandate.php",
data: "mandate_array="+JSON.stringfy(mandate_array)+"&role_id="+$('#role').val()+"&user_id="+$('#user').val(),
success: function(msg)
{
console.log(msg)
}
})
In PHP code
var_dump(json_decode($_POST['mandate_array']));
Use echo in front of the count()
Actually the following function works fine, but now I need to add other variable in order to return from the php file the right statement.
function sssssss1(page) {
loading_show();
$.ajax({
type: "GET",
url: "load_data.php",
data: "page=" + page,
success: function (msg) {
$("#search").ajaxComplete(function (event, request, settings) {
loading_hide();
$("#search").html(msg);
});
}
});
}
I need to add the following two variable to be read by my php file. I have tried different solution, but nothing seem working
var form2 = document.myform2;
var dataString1 = $(form2).serialize();
How to add those variable in my existing function? Any idea?
You can send object as data,
this line:
data: "page="+page,
could be
data: {mypage:"page="+page, form2:document.myform2, dataString1:$(form2).serialize()}
and your PHP can get it like:
$page = $_GET['mypage'];
$form2 = $_GET['form2'];
$dataString = $_GET['dataString1'];
Hope it Help.
I've created one Ajax function like this:
function searchPlanAjax(url){
jQuery('#loader').css('display','block');
var plan = jQuery('.rad').val();
var site = url+"fbilling_details/subscription";
jQuery.ajax({
type: "POST",
url: site,
data: "plan="+plan,
//data: "business_name="+val+"&bs="+bs,
success: function(msg){
jQuery('#loader').css('display','none');
}
});
}
Which I'm calling on radio button's onclick:
<?php echo $form->text(BILLING_DETAIL.'][id_plan', array('type'=>'radio', 'value'=>$val[PLAN]['id'], 'id'=>'id_plan_'.$val[PLAN]['id'], 'class'=>'rad','onclick'=>'searchPlanAjax('."'".SITE_NAME.ROOT_FOLDER_NAME."'".')')); ?>
The Ajax call will be processed in controller of cakePHP like this:
if(!empty($_REQUEST['plan'])){
$search_plan = $this->{PLAN}->find("all",array("conditions"=>array("id=".$_REQUEST['plan'])));
$this->set('search_plan',$search_plan);
}
but I couldn't get value in $search_plan variable. thanks if anybody can help.
Look at conditions in your find query
if(!empty($_REQUEST['plan'])){
$search_plan = $this->{PLAN}->find("all",array("conditions"=>array("id" => $_REQUEST['plan'])));
$this->set('search_plan',$search_plan);
}
I need (recently) to get an array from the server after an ajax call created by jquery. I know that i can do it using JSON. But i don't know how to implement it with JQuery (im new with JSON). I try to search in internet some example, but i didnt find it.
This is the code :
// js-jquery function
function changeSponsor() {
$.ajax({
type: 'POST',
cache: false,
url: './auth/ajax.php',
data: 'id=changespon',
success: function(msg) {
// here i need to manage the JSON object i think
}
});
return false;
}
// php-server function
if((isset($_POST['id'])) && ($_POST['id']=="changespon")) {
$linkspon[0]="my ";
$linkspon[1]="name ";
$linkspon[2]="is ";
$linkspon[3]="marco!";
echo $linkspon;
}
in fact, i need to get the array $linkspon after the ajax call and manage it. How can do it? I hope this question is clear. Thanks
EDIT
ok. this is now my jquery function. I add the $.getJSON function, but i think in a wrong place :)
function changeSponsor() {
$.ajax({
type: 'POST',
cache: false,
url: './auth/ajax.php',
data: 'id=changespon',
dataType: 'json',
success: function(data) {
$.getJSON(url, function(data) { alert(data[0]) } );
}
});
return false;
}
Two things you need to do.
You need to convert your array to JSON before outputting it in PHP. This can easily be done using json_encode, assuming you have a recent version of PHP (5.2+). It also is best practice for JSON to use named key/value pairs, rather than a numeric index.
In your jQuery .ajax call, set dataType to 'json' so it know what type of data to expect.
// JS/jQuery
function changeSponsor() {
$.ajax({
type: 'POST',
cache: false,
url: './auth/ajax.php',
data: 'id=changespon',
dataType: 'json',
success: function(data) {
console.log(data.key); // Outputs "value"
console.log(data.key2); // Outputs "value2"
}
});
return false;
}
// PHP
if((isset($_POST['id'])) && ($_POST['id']=="changespon")) {
$linkspon["key"]= "value";
$linkspon["key2"]= "value2";
echo json_encode($linkspon);
}
1) PHP: You need to use json_encode on your array.
e.g.
// php-server function
if((isset($_POST['id'])) && ($_POST['id']=="changespon")) {
$linkspon[0]="my ";
$linkspon[1]="name ";
$linkspon[2]="is ";
$linkspon[3]="marco!";
echo json_encode($linkspon);
}
2) JQUERY:
use $.getJSON(url, function(data) { whatever.... } );
Data will be passed back in JSON format. IN your case, you can access data[0] which is "my";
