Question

I’m sending user data via jQuery to TCPDF, but it does not display any value received from jQuery in the PDF file.

I have even tried to capture the value in a session variable but it still doesn’t display. Where am I going wrong?

HTML:

<div id="p">
    FOO
    <input type="text" id="nop" />
</div>

 <div id="e_table">
                <table>
                    <thead>
                        <th><h3>ABC</h3></th>
                        <th><h3>PQR</h3></th>
                        <th><h3>XYS</h3></th>
                    </thead>
                    <tbody>
                    <tr>
                        <td>Staff</td>
                        <td><input type="text" id="as" /></td>
                        <td><label id="las">label</label></td>
                    </tr>
                    <tr>
                        <td>Office</td>
                        <td><input type="text" id="bo"/></td>
                        <td><label id="lbo">label</label></td>
                    </tr>
                    <tr>
                        <td>Administrative</td>
                        <td><input type="text" id="mca" /></td>
                        <td><label id="lmca">label</label></td>
                    </tr>
                    </tbody>
                </table>
</div>

jQuery:

$('#pdf').click(function() {                    
                    var nop = $('#nop').val();
                    var as = $('#as').val();
                    var las = $('#las').text();
                    var bo = $('#bo').val();
                    var lbo = $('#lbo').text();
                    var mca = $('#mca').val();
                    var lmca = $('#lmca').text();

                    var postData = {
                         "nop" : nop,
                         "as" : as,
                         "las" : las,
                         "bo" : bo,
                         "lbo" : lbo,
                         "mca" : mca,
                         "lmca" : lmca
                    };

                    $.ajax({
                            type: "POST",
                            url: "pdf.php",
                            data: postData, 
                            success: function(data){
                                window.open("pdf.php"); 
                            }

Answer 1

you are calling your pdf.php 2 times, one with the post data, and one without

$.ajax({ // call 1, with post data
    type: "POST",
    url: "pdf.php",
    data: postData, 
    success: function(data){
        window.open("pdf.php"); // call 2, without post data
    }
});

what you can do is to remove your ajax request, and send the data via GET instead with

var getString = "nop=" + nop "&as=" + as; // .....
window.open("pdf.php?" + getString);
