Call functions and class in PHP and HTML page

This request is clear and relevant.
This request is not clear or is not relevant.


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
        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?

      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?
