Question

Here is the extract of my code that display the excel entries and stores into array .

The logic is first, detect which entry is invalid , mark it down, then for other valid entry, check whether it is duplicate, if it is, mark it down.

Eventually , scan through the whole sheet again, retrieve all the entries that is not in that two list. (duplicate or invalid)

The problems of it are:

1) When i display the table, although it can display but it warns me that ”
datatables warning:Request unknown parameter ‘0’ from the data source for row 0″

2) When i store into array, it can only store for the first line of row

So , i would like to know are there any mistake in my looping logic? and had i used the PHPEXCEL to read spreadsheet in a correct way? Thank you.

$reader = PHPExcel_IOFactory::createReader($readerType);
$PHPExcel = $reader->load($file);
$sheet = $PHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());

$pattern="/^[\w-]+(?:\.[\w-]+)*@(?:[\w-]+\.)+[a-zA-Z]{2,7}$/";

for ($row = 1; $row <= $highestRow; $row++){
for ($head = 0; $head < $highestColumn; $head++){
$testMail = $sheet->getCellByColumnAndRow($head, $row)->getValue();
if (preg_match($pattern,$testMail))
$mailColumn=$head;
}}
if(!isset($mailColumn))
{die('No email column detected, please check your file and import again.');}


$invaild[] = NULL ;
$email[] = NULL ;
$duplicate[] = NULL ;

for ($row = 1; $row <= $highestRow; $row++) {
    for ($y = 0; $y < $highestColumn; $y++) {
    $val = $sheet->getCellByColumnAndRow($y, $row)->getValue();

    if ($y == $mailColumn && !preg_match($pattern,$val))
    {$invaild[]=$row;}
    elseif ($y == $mailColumn && in_array($val,$email))
    {$duplicate[]=$val;
    $duplicate[]=$row;}
    //elseif (!in_array($row,$duplicate) && !in_array($row,$invaild) )
    //{echo $val;}

    if ($y == $mailColumn)
    {$email[]=$val;
    $email=array_unique($email);}

  }
}
$invaild=array_unique($invaild);


foreach ($invaild as $c)
{echo $c;}
echo "<br>";

Answer 1

Here is my tried code that uses ur logic.. I have passed excel file.(test.xlsx)

<?php
    /** PHPExcel */
    include_once('PHPExcel.php');

    /** PHPExcel_Writer_Excel2007 */
    include_once('PHPExcel/Writer/Excel2007.php');

    include_once('PHPExcel/Reader/Excel2007.php');

    //$objPHPExcel = new PHPExcel();

    $file = 'test.xlsx';
    $readerType = 'Excel2007';

    $reader = PHPExcel_IOFactory::createReader($readerType);
$PHPExcel = $reader->load($file);
$sheet = $PHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());

$pattern="/^[\w-]+(?:\.[\w-]+)*@(?:[\w-]+\.)+[a-zA-Z]{2,7}$/";

for ($row = 1; $row <= $highestRow; $row++){
for ($head = 0; $head < $highestColumn; $head++){
$testMail = $sheet->getCellByColumnAndRow($head, $row)->getValue();
if (preg_match($pattern,$testMail))
$mailColumn=$head;
}}
if(!isset($mailColumn))
{die('No email column detected, please check your file and import again.');}


$invaild[] = NULL ;
$email[] = NULL ;
$duplicate[] = NULL ;

for ($row = 1; $row <= $highestRow; $row++) {
    for ($y = 0; $y < $highestColumn; $y++) {
    $val = $sheet->getCellByColumnAndRow($y, $row)->getValue();

    if ($y == $mailColumn && !preg_match($pattern,$val))
    {$invaild[]=$row;}
    elseif ($y == $mailColumn && in_array($val,$email))
    {$duplicate[]=$val;
    $duplicate[]=$row;}
    //elseif (!in_array($row,$duplicate) && !in_array($row,$invaild) )
    //{echo $val;}

    if ($y == $mailColumn)
    {$email[]=$val;
    $email=array_unique($email);}

  }
}
$invaild=array_unique($invaild);


/*foreach ($invaild as $c)
{echo $c;}
echo "<br>";
foreach ($duplicate as $d)
{echo $d;}*/

?>


<div id="stylized" class="view">

if ($head==$mailColumn)
echo "<th field='col' $head> Email address </th>";
else

}
?>
</tr>
</thead>

<?php
for ($row = 1; $row <= $highestRow; $row++) {
            //Here I have added condition
    if (!in_array($row,$duplicate) && !in_array($row,$invaild)){
        echo "<tr>";
    }
    for ($y = 0; $y < $highestColumn; $y++) {
        if (!in_array($row,$duplicate) && !in_array($row,$invaild)){
            $val = $sheet->getCellByColumnAndRow($y, $row)->getValue();
            echo "<td>";
            if (!$val)
            echo "-";
            else

        echo "</tr>";   
    }
    }



?>

Here is source of the output.

Well I have tried dataTable jQuery Plugin and its working perfectly..
Have a look at the link http://datatables.net/forums/discussion/1283/warning-unexpected-number-of-td-elements./p1

My suggestion : please go thru your jquery dataTables plugin integration. Make sure that you are including required jquery in your output page of excel sheet with matching class or id selector like

$(document).ready(function() {
    $('#viewImport').dataTable();
} );

Edit : Check this out…

    include_once('PHPExcel/Reader/Excel2007.php');

    //$objPHPExcel = new PHPExcel();

    $file = 'test.xlsx';
    $readerType = 'Excel2007';

    $reader = PHPExcel_IOFactory::createReader($readerType);
$PHPExcel = $reader->load($file);
$sheet = $PHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = PHPExcel_Cell::columnIndexFromString($sheet->getHighestColumn());

$pattern="/^[\w-]+(?:\.[\w-]+)*@(?:[\w-]+\.)+[a-zA-Z]{2,7}$/";

for ($row = 1; $row <= $highestRow; $row++){

$invaild[] = NULL ;
