Call functions and class in PHP and HTML page

+1	I have an HTML page with some text fields. When the user enters the text fields, it should call either a function or class of PHP. I appreciate your support.

There are two ways you can call PHP,

1) onchange element function make an api call <script> $(document).ready(function(){ $("#elementid").change(function(){
```
// make an api call
$.ajax({
    type: "POST",
    url: url,
    data: data,
    success: success,
    dataType: dataType
});
```
}); }); </script>

2) Call the function explicitly in onchange element function <?php
```
function alertDialog(){
    echo "alert('PHP function called.');";
}
```
?> some html code... <script> $(document).ready(function(){ $("#fname").change(function(){
```
// call PHP function explicitly
<?php alertDialog(); ?>
```
}); }); </script>

Are you talking about as soon as the user enter some text/input, the data is sent to a backend and then return a resulting indicating the input is correct or wrong or this and that or returns data according what the user typed?

Jaxon: Call PHP classes from JavaScript using AJAX

This package can call PHP classes from JavaScript using AJAX.

It can register objects of classes or global functions and process AJAX requests that are handled by the registered functions.

The package can register directories of classes, so it is not necessary to register each class in each directory at once, with support to namespaces.

The classes are autoloaded on demand, so only the classes that necessary for each AJAX request will be loaded.

The AJAX calls are done by a separate JavaScript library which can eventually be retrieved from a CDN (Content Delivery Networt) so it does not have to be installed by this package.

Hello Sufyiian,

The JAXON package does what you need. It can generate JavaScript to send requests to PHP on the server side, so you can implement responses with the information that your forms need on the browser side to process those responses with JavaScript code.

Can you test this package and let us know if it works for you or if you need something better?
