    Sorry, forgive me, as its the blind leading the blind. But as nobody had come in yet, I did a google search for the error you were getting, don't know if this link is of any help. Regards

    Losing my POST values

    in PHP Coding Help

    I can paste the where statement for the first submission:

    WHERE GGroup IN ('1','2')

    however on selecting the next page, I cannot get anything other than:

    WHERE GGroup IN (Problem with query: select Orderdate
    as Ordered,product as Description,item as Code,Duration
    ,Qty as Quantity,unitprice as Unit,runningtotal as SubTotal
    from orders WHERE GGroup IN ( You have an error in your
    SQL syntax; check the manual that corresponds to your MySQL
    server version for the right syntax to use near '' at line 1

    Also in moving to page 2 the checkbox drops out of being checked, so maybe that causes the error. If I just keep hitting submit, in other words just keep returning the form/page while on page 1, there are no errors. Thanks

    Many thanks for still being in there. I tried the code but it rejected the SQL select statement when trying to goto the next page, it was rejecting the where statement. I know the statement is being built as I have echoed it. Why is life so easy? Thanks again

    Sitting here, tearing the last strands of hair from my head, I just wonder why I am going down the page pagination route to show a long broken up HTML table when I am submitting the same page back to me. Is there a way to just refil the table each time with ascending/descending query limts, values held in session variables, which simply get counted up/down? Thanks

    Thanks. Yes the WHERE string is being passed to the SELECT query,

    This part works okay after first pass after checkboxes set, and on repetitive submissions.

    if (isset($_POST['X1'])) {
        if (count($_POST['product'])) {
        $prodlist = join("','", $_POST['product']);
        $where = "WHERE GGroup IN ('$prodlist')";
        }
        }

    The WHERE statement gets added in as:

    .....from orders [b]$where [/b] order by Orderdate, PIndex $limit";

    If I didn't have to extend my page to accomodate longer HTML tables being displayed, then all the code worked fine. I was about to add in To/From order dates to complete the page before I then realised my HTML tables could end up quite long.

    I tried the following, but with same results, could very well have misinterpreted suggestion:

    [code]if ($pagenumber == 1) {
      echo " First Previous ";
    } else {
      echo " <a href='{$_SERVER['PHP_SELF']}?pagenumber=1&where=$where'>First</a> ";
      $prevpage = $pagenumber-1;
      echo " <a href='{$_SERVER['PHP_SELF']}?pagenumber=$prevpage&where=$where'>Previous</a> ";
    }

    echo " ( Page $pagenumber of $lastpage ) ";

    if ($pagenumber == $lastpage) {
      echo " Next Last ";
    } else {
      $nextpage = $pagenumber+1;
      echo " <a href='{$_SERVER['PHP_SELF']}?pagenumber=$nextpage&where=$where'>Next</a> ";
      echo " <a href='{$_SERVER['PHP_SELF']}?pagenumber=$lastpage&where=$where'>Last</a> ";
    }[/code]


    Modified all href lines. Thanks again

    Thanks, I will try and explain. The page/form has six checkboxes on representing 6 product types contained within a table containing archived orders. An HTML table displays the contents of the order table. However a user may wish to show only one or selected product types in the table, so they leave checkboxes checked or unchecked, and press submit which resubmits the same form back, the contents of the checkboxes perform a creation of the WHERE statement used in the database query. The status of checkboxes did remain in the conditions they were set, however selecting further pages in pagnitation cause the checkboxes to drop out and the query reverts to all records when page 2 of the table is shown.

    Hope you are with me so far.

    So when it was just the same page returned there were no problems, but in adding extension pages for long HTML tables I have this problem.

    Thanks. However I tried it out and I lose my checkbox settings if I submit the page back to itself. Its all been working fine until I introduced page pagination, and its when I change the pages I lose my checkbox settings.

    Don't know if something in here would be the reason?

    [code]if ($pagenumber == 1) {
      echo " First Previous ";
    } else {
      echo " <a href='{$_SERVER['PHP_SELF']}?pagenumber=1'>First</a> ";
      $prevpage = $pagenumber-1;
      echo " <a href='{$_SERVER['PHP_SELF']}?pagenumber=$prevpage'>Previous</a> ";
    }

    echo " ( Page $pagenumber of $lastpage ) ";

    if ($pagenumber == $lastpage) {
      echo " Next Last ";
    } else {
      $nextpage = $pagenumber+1;
      echo " <a href='{$_SERVER['PHP_SELF']}?pagenumber=$nextpage'>Next</a> ";
      echo " <a href='{$_SERVER['PHP_SELF']}?pagenumber=$lastpage'>Last</a> ";
    }[/code]

    Thanks

    I have a series of checkboxes on a form/page. I use the code below which maintains there settings on page re submission.

    [code]<?

            $products = array (
            1 => 'Digital Betacam',
            2 => 'Betacam SP',
            3 => 'DVCPro',
            4 => 'HDCAM',
            5 => 'Mini DV'
        );

          foreach ($products as $id =>$prod) {
            if ($_POST['product']) {
                // was value of id in those posted?
                $chk = in_array($id, $_POST['product']) ? 'checked' : '';
            }
            else $chk = '';
    ?>        [/code]


    However, now I am using page pagination, the checkbox's lose there checked/unchecked status when paging. Any idea how I prevent this happening. Many thanks
