MySql and PHP - Fetch next row in a while loop

Question

I have a MySQL query which selects scan details from the database. Those details are placed in a report. It was requested to have the reports displaying in two columns (almost two tables) on one page, to preserve the space that it takes.

What I am currently doing is displaying the table header:

 $report .= ">
                    <table cellspacing='0' class='at_report'>
                        <thead>
                            <tr><th colspan='8'>Area ".$row['area_name']."</th></tr>
                        </thead>
                        <tr>
                            <td class='simple_header' style='width:7%;'><div class='nosplit'>No.</div></td>
                            <td class='simple_header' style='width:8%;'><div class='nosplit'>Barcode</div></td>
                            <td class='simple_header' style='width:40%;'><div class='nosplit'>Product</div></td>
                            <td class='simple_header' style='width:5%;'><div class='nosplit'>Qty</div></td>
                            <td class='simple_header' style='width:7%;'><div class='nosplit'>Cost Value</div></td>
                            <td class='simple_header' style='width:16%;'><div class='nosplit'>Created By</div></td>
                            <td class='simple_header' style='width:10%;'><div class='nosplit'>Time</div></td>
                            <td class='simple_header' style='width:7%;'><div class='nosplit'>No.</div></td>
                            <td class='simple_header' style='width:8%;'><div class='nosplit'>Barcode</div></td>
                            <td class='simple_header' style='width:40%;'><div class='nosplit'>Product</div></td>
                            <td class='simple_header' style='width:5%;'><div class='nosplit'>Qty</div></td>
                            <td class='simple_header' style='width:7%;'><div class='nosplit'>Cost Value</div></td>
                            <td class='simple_header' style='width:16%;'><div class='nosplit'>Created By</div></td>
                            <td class='simple_header' style='width:10%;'><div class='nosplit'>Time</div></td>
                        </tr>
                         ";

Then I fetch the results from the database:

 while ($srow = $scan_res->fetch(PDO::FETCH_ASSOC))

Then I display the results in the table:

 $report .= "<tr ".$row_style.">
                                <td><div class='nosplit'>".$n."</div></td>
                                <td><div class='nosplit'>".$srow['barcode']."</div></td>
                                <td><div class='nosplit'>".$product_nd_short."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$rounded_qty."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$cur_symbol.$cn.$mcost_estimated."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".((strlen($srow['stocktake_staff_name'])>16)? substr($srow['stocktake_staff_name'], 0, 16)."..." : $srow['stocktake_staff_name'])."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$dt->format('H:i:s')."</div></td></tr>";

My question is, how do I go to the next set of results in the while loop, so that I can add another column with set of results in the table? I tried this:

$report .= "<tr ".$row_style.">
                                <td><div class='nosplit'>".$n."</div></td>
                                <td><div class='nosplit'>".$srow['barcode']."</div></td>
                                <td><div class='nosplit'>".$product_nd_short."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$rounded_qty."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$cur_symbol.$cn.$mcost_estimated."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".((strlen($srow['stocktake_staff_name'])>16)? substr($srow['stocktake_staff_name'], 0, 16)."..." : $srow['stocktake_staff_name'])."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$dt->format('H:i:s')."</div></td>";       
                $row_counter++;     
                $n++;
                   $report .= "
                                <td><div class='nosplit'>".$n."</div> </td>
                                <td><div class='nosplit'>".$srow['barcode']."</div></td>
                                <td><div class='nosplit'>".$product_nd_short."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$rounded_qty."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$cur_symbol.$cn.$mcost_estimated."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".((strlen($srow['stocktake_staff_name'])>16)? substr($srow['stocktake_staff_name'], 0, 16)."..." : $srow['stocktake_staff_name'])."</div></td>
                                <td style='text-align:center;'><div class='nosplit'>".$dt->format('H:i:s')."</div></td> 
                            </tr>";

But all it does is duplicating the result from the first set.

Thanks!

May be you need something like this.

You want to place the 2 result in a same row.

$n = 1;
while($srow = $scan_res->fetch(PDO::FETCH_ASSOC)){
    if($n % 2 != 0)
        $report .= "<tr ".$row_style.">";

    $report .= "<td><div class='nosplit'>".$n."</div></td>
              <td><div class='nosplit'>".$srow['barcode']."</div></td>
              <td><div class='nosplit'>".$product_nd_short."</div></td>
              <td style='text-align:center;'><div class='nosplit'>".$rounded_qty."</div></td>
              <td style='text-align:center;'><div class='nosplit'>".$cur_symbol.$cn.$mcost_estimated."</div></td>
              <td style='text-align:center;'><div class='nosplit'>".((strlen($srow['stocktake_staff_name'])>16)? substr($srow['stocktake_staff_name'], 0, 16)."..." : $srow['stocktake_staff_name'])."</div></td>
              <td style='text-align:center;'><div class='nosplit'>".$dt->format('H:i:s')."</div></td>";
    if($n % 2 == 0)
        $report .= "</tr>";
    $n++;
}

Ehm,

its a bit confusing your question, but i think i know what you mean....

while ($srow = $scan_res->fetch(PDO::FETCH_ASSOC))
{
    $n++;
    $report .= "<tr><td><div class='nosplit'>".$n."</div></td>
                <td><div class='nosplit'>".$srow['barcode']."</div></td>
                <td><div class='nosplit'>".$product_nd_short."</div></td>
                <td style='text-align:center;'><div class='nosplit'>".$rounded_qty."</div></td>
                <td style='text-align:center;'><div class='nosplit'>".$cur_symbol.$cn.$mcost_estimated."</div></td>
                <td style='text-align:center;'><div class='nosplit'>".((strlen($srow['stocktake_staff_name'])>16)? substr($srow['stocktake_staff_name'], 0, 16)."..." : $srow['stocktake_staff_name'])."</div></td>
                <td style='text-align:center;'><div class='nosplit'>".$dt->format('H:i:s')."</div></td></tr>";
}

i haven't tried running it ... but it should do what you want.

• make sure you have the statements you want to repeat inside the curly braces {} after your while statement
• make sure to start row with and end it with
• you only use barcode and stock_staff_name variables from your data rows ... other values you seem to have pre set ... so those will always be the same ($rounded_qty, $dt, $product_nd_short .... so if you would like this to be from your row ... then read them from your row in your while statement.
