reset hidden variable after posting the form

Recommended Posts

I want to download the records of the output of search criteria to excel.

As the fields for search criteria are more than 20. I am submitting the form with POST method rather than GET.

 

On click of  "Download2excel", the hidden variable name1 is set to Yes. so i will check the condition in my code. Once the download is successful, I want to reset the variable.

 

 

Here is a sample structure of my code.

 

        <html>
        <head>
            <?php
            if(trim($_POST['name1']) == 'yes') {
                header("Content-type: application/vnd-ms-excel");
                header("Content-Disposition: attachment; filename=$filename.xls");
            }else {
                ?>
        </head>
        <body onload="tempFn()">
    
            <script language="javascript" type="text/javascript">
                function tempFn(){  
                    global_search.name1.value = "";
                }
                function gs_download2xl_c() {
                    document.getElementById('name1').value="yes";
                    document.global_search.submit();
                }
            </script>
            <form name="global_search" id="global_search" action="test_1.php" method="POST">
                <input type="text" id="name1" name="name1" />
                <a  class="underline"  style="cursor: pointer" onclick="gs_download2xl_c();">
                    Download2excel
                </a>
            </form>
                <?php } ?>
        </body>
    </html>

As i am not executing the form after posting the form, i am not able to access the variable name1 is in it. I want to reset the variable name1.

 

I want to trigger the download, after submitting the form. As the records that are downloaded to excel should obey input search criteria.

 

 

Please suggest me a better procedure.
