PHPExcel verify if cell has empy value - php

Question

Hello i have an import of an xls file with multiple rows on it and i want to insert them into database only if the price columns has a value different than nothing else display an error msg. It works on half it only inserts those rows that have a value for price but instead returning the html error msg it returns the sql msg, that means it goes on the else branch.
Here is my code
$exceldata = array();
$uploadFilePath = 'uploads/'.basename($_FILES['doc']['name']);
move_uploaded_file($_FILES['doc']['tmp_name'], $uploadFilePath);
$inputfilename = 'uploads/'.$_FILES['doc']['name'].'';
// Read your Excel workbook
try
{
$inputfiletype = PHPExcel_IOFactory::identify($inputfilename);
$objReader = PHPExcel_IOFactory::createReader($inputfiletype);
$objPHPExcel = $objReader->load($inputfilename);
}
catch(Exception $e)
{
die('Error loading file "'.pathinfo($inputfilename,PATHINFO_BASENAME).'": '.$e->getMessage());
}
// Get worksheet dimensions
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
$header=$_POST['membership'];
if($header==1)
{
// Loop through each row of the worksheet in turn
for ($row = 1; $row <= $highestRow; $row++)
{
// Read a row of data into an array
$rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row, NULL, TRUE, FALSE);
if ($rowData[0][9]=='')
{
echo 'No price for the product '.$rowData[0][1].'';
}
else
{
$a = array('8', '1', '2', '3', '4', '5','6');
$b = array($rowData[0][0], $rowData[0][2], $rowData[0][3],$rowData[0][5],$rowData[0][6],$rowData[0][8],$rowData[0][8]);
$c = array_combine($a, $b);
$slug = str_replace(" ", "-",$rowData[0][1]);
$slug = str_replace('"', "",$slug);
$slug = str_replace('/', "-",$slug);
$stmt=$dbh->prepare("INSERT INTO tbl_products (name,slug,description,price)
VALUES (:name,:slug,:desc,:pret)");
$stmt->bindParam(":name",$rowData[0][1]);
$stmt->bindParam(":slug",$slug);
$stmt->bindParam(":desc",$rowData[0][10]);
$stmt->bindParam(":pret",$rowData[0][9]);
$stmt->execute();
$id_product=$dbh->lastInsertId();
$stmt=$dbh->prepare("INSERT INTO tbl_products_images_gallery (id_product,name,image,sort_order)
VALUES (:id,:name,:image,100)");
$stmt->bindParam(":id",$id_product);
$stmt->bindParam(":name",$rowData[0][4]);
$stmt->bindParam(":image",$slug);
$stmt->execute();
$stmt=$dbh->prepare("SELECT id_category from tbl_catalog_categories where name=:name");
$stmt->bindParam(":name",$rowData[0][2]);
$stmt->execute();
if($row=$stmt->fetch())
{
$id_cat=$row['id_category'];
}
$stmt=$dbh->prepare("INSERT INTO tbl_products_to_categories (id_category,id_product)
VALUES (:id_cat,:id_prod)");
$stmt->bindParam(":id_cat",$id_cat);
$stmt->bindParam(":id_prod",$id_product);
$stmt->execute();
foreach($c as $key => $value)
{
$stmt=$dbh->prepare("INSERT INTO tbl_products_attributes_values (id_product,id_attribute,attribute_value)
VALUES (:id_product,:id_attribute,:value)");
$stmt->bindParam(":id_product",$id_product);
$stmt->bindParam(":id_attribute",$key);
$stmt->bindParam(":value",$value);
$stmt->execute();
}
}
}
}

if (empty($rowData[0][9])) perhaps?
Or test for null as well as for empty strings - nulls are perfectly valid response from PHPExcel...
especially as
$rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row, NULL, TRUE, FALSE);
with it's null second argument is telling PHPExcel to return a null value if the cell simply doesn't exist in the spreadsheet
Though you can change the rangeToArray() call to
$rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row, '', TRUE, FALSE);
to return an empty string instead of a null if the cell doesn't exist
