    resolved [RESOLVED] Post HTML form data to a text file using AJAX & PHP

    I am trying to post 4 HTML form fields to a text file using AJAX & PHP
    The full HTML form has other fields. The whole form will be posted to a different location after.

    need some sample code if possible.

    PHP variables are

    PHP Code:
    $username $_POST['username'];
    $realname $_POST['realname'];
    $phone $_POST['phone'];
    $email $_POST['email'];

    Or without jQuery,

    HTML Code:
    function sendFields(e) {
        e.preventDefault();
        var form = e.srcElement ? e.srcElement : e.target;
        var username = form.username.value;
        var realname = form.realname.value;
        var phone = form.phone.value;
        var email = form.email.value;
    
        var xhr = new XMLHttpRequest();
        xhr.open("POST","path-to-your-receiving-file.php",true);
        xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
        xhr.send("username="+username+"&realname="+realname+"&phone="+phone+"&email="+email);
        xhr.onreadystatechange = function() {
            if(xhr.readyState == 4 && xhr.status == 200) {
                //response from the php page
                var response = xhr.response;
            }
        }
    }
    
    var form = document.getElementById('form');
    form.addEventListener('submit',sendFields);

    Apologies for brevity. With jQuery:

    Code:
    <script>
    $(function(){
       
        $('button#send').click(function(){
            var field1 = $('input#field1').val();
            $.post('somephpfile.php',{field1:field1},function(data){
                //If you're returning your output in JSON format we can use data.response to inject feedback into our page to inform the user etc.
            },'json');
        });
    
    });
    </script>
    
    <input id="field1" /> 
    <button id="send">Submit</button>
    The above code assumes you have the jQuery library loaded already.

    Note: I've written this code on the fly. This hasn't be tested.

    Hi All:

    Thanks for all the information & assistance.

    I DO NOT have to use jQuery. The HTML & Javascript is preferable for me at this time.

    I did not see that the last part of my post was cut off. Sorry about that.

    On the PHP end, I usually have my text file setup like this:

    PHP Code:

    $data 
    "$username | $realname  | $phone | $email\r\n";

    //open the file and choose the mode   This adds data to the text file   newusers.txt
    $fh fopen("mydata/newusers.txt""a");
    fwrite($fh$data);

    //close the file
    fclose($fh); 
    What I'm trying to understand is how do I change the PHP end to accomodate the AJAX posting.

    The PHP is supposed to return a string to a hidden form field on the form that did the submission.
    I really want to return the string as $phone & Time

    It should look like 7185551212-11:45 when its in the hidden form field. The form name is UserForm.php

    Appreciate all your help.

    Thanks

    Padonak:
    Thanks.
    Thats exactly what I was looking for, and the PHP was very well documented.
    I can follow what's going on.
