PHPEXCEL mysql php insert empty rows - mysql

Question

I am trying to use phpexcel to let users upload a spreadsheet and insert into mysql. I have it working except if the user has blank rows in the spreadsheet it puts several unnecessary rows in the database. I have read and mysql doesnt support check constraints and most of that would need to be done at the application level which is what I am trying to do. How in PHP could have it check if a specific column is empty and skip that row. Any help would be appreciated or if there is a better solution I am up for all options. I was trying for a while to get it that is the bldg column was empty than just skip that row but wasnt having any luck..
<?php require '../Classes/PHPExcel.php';
require_once '../Classes/PHPExcel/IOFactory.php';
$path = "../upload/uploads/$Filename";
$objPHPExcel = PHPExcel_IOFactory::load($path);
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
$worksheetTitle = $worksheet->getTitle();
$highestRow = $worksheet->getHighestRow();
$highestColumn = 'L'; // e.g 'F'
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
$nrColumns = ord($highestColumn) - 64;
$objReader = PHPExcel_IOFactory::createReaderForFile($path);
$objReader->setReadDataOnly(true);
echo '<br>Data: <table width="100%" cellpadding="3" cellspacing="0"><tr>';
for ($row = 16; $row <= $highestRow; ++ $row) {
echo '<tr>';
for ($col = 0; $col < $highestColumnIndex; ++ $col) {
$cell = $worksheet->getCellByColumnAndRow($col, $row);
$val = $cell->getValue();
if($row === 1)
echo '<td style="background:#000; color:#fff;">' . $val . '</td>';
else
echo '<td>' . $val . '</td>';
}
echo '</tr>';
}
echo '</table>';
for ($row = 16; $row <= $highestRow; ++ $row) {
$val=array();
for ($col = 0; $col < $highestColumnIndex; ++ $col) {
$cell = $worksheet->getCellByColumnAndRow($col, $row);
$val[] = $cell->getValue();
}
$sql="insert into excess1(date_excessed, bldg, floor, jack, equipment_owner, contact_name, contact_phone, qty, type_of_excess, asset_tag, service_tag, comments)
values('".$val[0] . "','" . $val[1] . "','" . $val[2]. "','" . $val[3]. "','" . $val[4]. "','" . $val[5]. "','".$val[6] . "','".$val[7] . "','".$val[8] . "','".$val[9] . "','".$val[10] . "','".$val[11] . "')";
$result = mysql_query($sql) or die(mysql_error());
print "$result";

$inputFileType = PHPExcel_IOFactory::identify($filename);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load($inputFileName);
$allDataInSheet = $objPHPExcel->getActiveSheet()->toArray(null, true, true, true);
$i=0;
foreach ($allDataInSheet as $value) {
if ($value === null){
continue;
} //this is skipping empty rows
$data[$i] = $value['A'];
$data[$i] = $value['B'];
$i++;
}
