How do I pass variables and data from PHP to JavaScript?
(19 answers)
Closed 3 years ago.
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'm trying to call a function inside controller that will return a echo
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');
Now it working

"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));

$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!

How to read an array in PHP inside JavaScript? Like this
<?php
$f(0)=69;
$f(1)=8;
$f(2)=25;
$f(3)=5;
$f(4)=32;
?>
<script>
var barChartData = {labels : ["Ene","Feb","Mar","Abr","May","Jun","Jul"],
datasets : [
{
fillColor : "#e64608", strokeColor : "#e64608",
data:[65,59,90,81,56,55,40]
},
{
fillColor : "#acadb1", strokeColor : "#acadb1", data :
[28,48,40,19,96,27,100]
}
]
}
var myLine = new
Chart(document.getElementById("bar").getContext("2d")).
Bar(barChartData);
</script>
I would like to replace the "data" in the data with the ones in the PHP array.
The best solution id to load data using ajax. Another option is to render data as follows.
<script>
var barChartData = <?php json_encode($array); ?>
</script>

how to pass these strings from php to javascript
(5 answers)
Closed 9 years ago.
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.

And my PHP
<?php
$pageid = $_GET['linkId2'];
print_r($_GET);
?>
So this is my code but it seems not working..Had looked around dint found anything that can help.
Explain the script
I want to take ID of a link and assign it to $pageid
The console.log(data); Saying Access Denied
print_r($_GET); Saying array();
If any suggestion with code.
If need more details please ask I will explain everything that I can.
Will appreciate any help. Thank you a lot.
There is an error in your jquery.ajax function. You missed to pass an identifier for the data. Use this:
data: {"linkId2" : linkId2},
