jQuery("#empy_card").hide()
var test_type= jQuery('#test_type').val();
var myvals = jQuery("#table").html('');
jQuery.ajax({
type: "POST",
url: "test.php?smt=command",
dataType: 'json',
data: {test_type:test_type},
success: function(data){
//alert(data.date);
//alert(data.book);
<?php
$date = data.date;
$book = data.book;
?>
}
});
}
its work successfully. i got in alert form data.date
"18-Dec-10","20-Apr-11"
i got in alert form data.book
"book A","book C"
test.php
<?php
if(isset($_GET['smt'])=='command'){
$test= $_POST['book_name'];
include('connection.php');
$data=array();
$result ="SELECT * FROM books WHERE Type_of_books='$test'";
$ftc = mysqli_query($conn,$result)or die(mysqli_error($conn));
while($row = mysqli_fetch_array($ftc)) {
$data['date'][] ='"'.$row['date'].'"';
$data['book'][] = $row['name'];
}
echo json_encode($data);
}
?>
how can i get this data to php variable like $dates = data.date; And $book = data.book
Why are you using php in Ajax and you are assigning JavaScript variable to php. If you really want that response use cookies or session variables.
Remember that your PHP code is evaluated by the server, not the client. That means that you can access your $date and $year in various ways.
Server side (PHP)
You have to delete your Ajax request and write it using PHP, then you can access the variables.
Client side (JavaScript)
You already got them in data!

but I get error as result show inside my id #ly-id-result
{"success":false,"message":"View not found [name, type, prefix]: places, raw, hpj_storemanagerView","messages":null,"data":null}
My Ajax call in : httpdocs/modules/mod_storemanager_map/tmpl/default.php
var ly_inputVal = document.getElementById("ly-val-inp").value;
jQuery.ajax({
url: "index.php?format=raw&option=com_storemanager&task=abc",
data: {text:ly_inputVal},
method: "POST", //Use post method
cache: false, //Specify no cache
success: function(result){
//console.log(ly_inputVal);
jQuery("#ly-id-result").html(result);
}
});
in my controller in : httpdocs/components/com_storemanager/controller.php
public function abc()
{
// Get Joomla's input object:
$input = JFactory::getApplication()->input;
// Get the variable
$value = $input->get('ly_inputVal');
return $value;
}
I found the error; I have to change
$value = $input->get('ly_inputVal');
to
$value = $input->get('text');

How do I pass variables and data from PHP to JavaScript?

I have several products. On click product, I send "id" of clicked product to Local Storage. To use this variable in php I send it to items.php ($.post).
Then I need use this "id" from items.php to show in the cart, but variable is emply.
var LSArray = JSON.parse(localStorage.getItem('productID')) || [];
function clickOnProduct(id) {
var newItem = {'id': id};
LSArray.push(newItem);
localStorage.setItem("productID", JSON.stringify(LSArray));
var dataLS = JSON.parse(localStorage.getItem('productID')) ;
$.ajax({
type : "POST",
url : "/wp-content/themes/twentynineteen/items.php",
data : { name : dataLS[dataLS.length-1].id },
success: function(res){
console.log(res);
}
});
}
All works fine, but how can I use "id"?
<?php incude(items.php); ?>
dosn't work.
You are sending it by post. So you can take a look to your post variable by
<?php var_dump($_POST); ?>
Then you will see the array and probably you can access your data by
$_POST['name']

I have that code:
function saveData(position, map) {
var latlng = marker.getPosition();
var late = latlng.lat();
var longe = latlng.lng();
<?php
require("sql.php");
session_start();
$name = 'prova';
$address = 'temare';
$type = 'bar';
$late = "<script>document.getElementByID('late').value</script>";
$longe ="<script>document.getElementByID('longe').value</script>";
I need to get late and longe variables in PHP but this doesn't work, anyone knows how I can do it?
You can't access javascript variables using PHP as JavaScript is executed on client side ( browser ) and PHP on server side.
The best what you can do is send data from those variables as request to server and read them, for example using jQuery ajax request:
Good example you can find here:
jQuery Ajax POST example with PHP
Or you can use this:
javascript
function sendData(variable1, variable2) {
$.ajax({
type: 'post',
url: 'myphpscript.php'
data: 'var1='+variable1+'&var2='+variable2
});
myphpscript.php
<?php
$variable1 = $_POST['var1'];
$variable2 = $_POST['var2'];
<script type="text/javascript">
<?php $abc = "<script>document.write(late)</script>"?>
<?php $def = "<script>document.write(longe)</script>"?>
</script>

I want to set session inside the javascript. But all the time this function return false value. Please tell me the error of this code.
<script>
function myFunction(){
var r=confirm("Would you like to add another item ?");
if (r==true) {
alert('ok');
var varname = '<?php echo $_SESSION["redirect"]=1; ?>';
}
if(r==false) {
alert('bad');
var varname = '<?php echo $_SESSION["redirect"]=2; ?>';
}
}
</script>
You can't evaluate PHP on the client. Do an AJAX request to the server setting the session variable instead.
Javascript runs on the client side, so you'll need to perform an AJAX call to a server side script that will change the sessions value.
Something in the lines of:
function changeSession()
{
$.ajax({
url: /change_session.php?value=1&key=redirect,
dataType:"html"
});
}
And in change_session.php:
<?php $_SESSION[$_REQUEST['key']]=$_REQUEST['value'] ?>

how to pass these strings from php to javascript

I need to pass a value from PHP back to my javascript. I have tried so many things but can't get it to work. Here is my code.
<script type="text/javascript">
life = {};
life.anjaxEnter = function(finished) {
$.ajax({
dataType:"json",
type:"POST",
data:mydata,
url:"myurl.php",
async:false,
success:life.receiveResult,
});
setTimeout("location.href='myredirectionurl'", 1000); // Redirect after 1 second
}
life.receiveResult = function(result) {
alert(result);
}
</script>
I need to pass a specific value from the PHP file back to life.receiveResult and then add this to the redirection url.
The biggest problem is probably that at the time when you assign life.receiveResult to success, life.receiveResult is undefined. You need to define it before you assign it to something else.
myurl.php needs to return a JSON result when it's called. Something like this:
<?php
header("Content-Type: text/json");
$mydata = "Hello";
echo json_encode(array('ok' => true, 'mydata' => $mydata));
?>
Have a look at the json_encode docs, the header docs and some of the other answers for more information.
