call function url page with ajax - php

Question

I have tried several times but it didn't work. I want to call the function nama() on the dom_area.php page.
This is dom_area as target
<?php
function nama()
{
echo $_POST['data_area'];
}
?>
and this is the page where I call the function
<button id='acc'>asas</button>
<script>
$(document).ready(function() {
$('#acc').click(function() {
let data_area = 2;
let url_address = "<?= 'dom_area.php/nama()'; ?>";
$.ajax({
url:url_address,
type:'post',
data:{data_area:data_area} ,
}).done(function(output){
console.log(output);
// alert(data);
});
// console.log(url);
});
});
</script>

Answer 1

You can only cause a php file to be launched, NOT a specific function within that script
However if you pass a parameter to control what to do in the script you can achieve what you are trying to do
<button id='acc'>asas</button>
<script>
$(document).ready(function(){
$('#acc').click(function(){
let data_area = 2;
$.ajax({
url:'dom_area.php', // the script file name
type:'post',
// add a control parameter
data:{control:"Nama", data_area:data_area},
}).done(function(output){
console.log(output);
// alert(data);
});
// console.log(url);
});
});
</script>
Now in the PHP
<?php
function nama()
{
echo $_POST['data_area'];
}
if ( $_SERVER['REQUEST_METHOD'] == 'POST' ) {
// form was submitted
switch($_POST['control'])
case 'Nama':
nama();
break;
default:
echo json_encode(['status'=>'failed']);
}
}
?>

try this:
<?php include_once('dom_area.php') ?>
<button id='acc'>asas</button>
<script>
$(document).ready(function(){
$('#acc').click(function(){
let data_area = 2;
let url_address = "<?= json_encode(nama()); ?>";
$.ajax({
url:url_address,
type:'post',
data:{data_area:data_area} ,
}).done(function(output){
console.log(output);
// alert(data);
});
// console.log(url);
});
});
</script>

Please try this in call part.
<button id='acc'>asas</button>
<script>
$(document).ready(function(){
$('#acc').click(function(){
let data_area = 2;
$.ajax({
url:'dom_area.php/nama',
type:'post',
data:{data_area:data_area} ,
}).done(function(output){
console.log(output);
// alert(data);
});
// console.log(url);
});
});
</script>
