Using getElementById()

**kakinyim** · 02-01-2011 11:50 AM

Hey gurus, I have a php form (form A) that when I click some button, it opens a popup window which is also a php page (form B). In the popup I enter some values and want to submit these values to form B.

I have tried document.getElementById() method while at form A to read form B hidden value id but i dont get any results. Is it possible to achieve this? Please assist.

If it's a "popup" window, then you won't be able to read the info from "form B" at "form A" unless you pass the information between each other. Do you have a link that demonstrates the scenario?

I have pasted the codes here. regAssignUser.php opens a popup files.php and then files.php close() to end data to regAssignUser.php

Code:

=================================
<!-- regAsignUser.php -->
====================================
<?php session_start(); ?>

<script type="text/javascript">
    function open_files()
    {
        var mySearch = document.getElementById("idFile");
        if(mySearch.value == ""){
            alert("You Have Not Entered Anything");
        }else{
        window.open('files.php?myList='+mySearch.value,'myExample','width=600,height=700,modal=yes, scrollbars=yes, location=no'); 
        }
    }
</script>

<script type="text/javascript">
    function readValue()
    {
        var XX = document.getElementById("myFileNoX");
        alert(XX.value);
    }
</script>

<?php

===========================================
<!-- file.php -->
========================================
<?php session_start(); ?>
<html>
    <head>
    </head>
    <body>
        <?php  $txtFile = $_GET['myList'];  ?>

        <script type="text/javascript">
            function submitForm()
            {
                document.forward.submit()
                close();    
            }
        </script>

        <script type="text/javascript">
            function closeNull()
            {
                close();
            }
        </script>
        <?php
        include_once('./Connections/myconn.php');
        $db = mysql_select_db('registryis', $myconn);
        if (!$db) {// if the database is not available
            $message = " There was a problem in trying to connect to the database.Please try later after sometime";
            mysql_error();
            exit;
        }

        $result = @mysql_query("select * from file where fileTitle like '&#37;$txtFile%' or fileNo like '%$txtFile%';");
        if (!$result) {
            exit('<p> Error performing query: ' . mysql_error() . '</p>');
        }

        $num = mysql_num_rows($result);
        if ($num == 0) {
        ?>
            <table width="75%" border="1" align="left" bgcolor="#CC99CC">
                <tr>
                    <td><div align="center" class="style1">Your Search Found No File(s) <BR>
                    <input type=button onClick="closeNull()" value='Close Window'> </div> </td>
                </tr>
            </table>

        <?php  } else {  ?>

            <table width="75%" border="1" align="center" bgcolor="#CC99CC" >
                <FORM NAME="forward" ACTION="regAssignUser.php" />
                <tr>
                    <td width="196"><strong>File Number</strong></td>

                <?php do {  ?>
                    <td><?php echo $row_qry['fileNo']; ?> </td>

                <?php $fileNo = $row_qry['fileNo'];  ?>
                <input type="hidden" name="myFileNo" id="myFileNoX" value = <?php echo $fileNo; ?> />
                <td><input type="radio" name="radSelect" value="Select" onClick ="submitForm()" /> </td>

            </tr>
        <?php } while ($row_qry = mysql_fetch_array($result)); } ?>

        </form>
    </table>
