So, I'm a fairly new PHP programmer and I'm trying to set up a page that uploads a file, displays the info in a table, then writes the data to a database.
I've got these things working (I found some helpful code online) however my dates are displaying incorrectly.
For example, the date "2/15/2017 17:55" is displaying as "42781.746527778".
Here is the code:
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());
}
echo '<center><table style="width:50%;" border=1>';
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
for ($row = 1; $row <= $highestRow; $row++) {
$rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,
NULL, TRUE, FALSE);
echo "<tr>";
foreach($rowData[0] as $k=>$v)
echo "<td>".$v."</td>";
echo "</tr>";
}
echo '</table></center>';
}
else{
echo '<p style="color:red;">Please upload file with xlsx extension only.</p>';
}
I get why it is displaying the date that way, however I'm not having luck in fixing it when trying to display the entire column as a date and time, or displaying it in a single cell as the correct date and time.
var_dump($objPHPExcel->getActiveSheet()->getCell('B2')->getFormattedValue());
This code displays the correct date and time for one of my sample spreadsheets, however I'm not able to get that value in the cell.
Any help would be appreciated. Thank you!
I believe this is what you are looking for? Check if the cell is a Excel date and time then extract and convert the Excel date to a PHP date.
if(PHPExcel_Shared_Date::isDateTime($k)) {
$v = date('Y-m-d', PHPExcel_Shared_Date::ExcelToPHP($v));
}

I'm having trouble in getting the correct characters from my .xls file.
Based on what I found on the internet, it seems that it has something to do with the encoding or its something about html that cant be read through PHPexcel. It says that for PHPExcel to read the file it has to be utf-8. Can you give me hints on how to get the correct encoding or getting to read it by utf-8?
Here's my code:
require_once 'Classes/PHPExcel.php';
include 'Classes/PHPExcel/IOFactory.php';
$pathgalleriadeclare = "C:\Users\Desktop\sample.xls";
try {
$inputfiletype = PHPExcel_IOFactory::identify($pathgalleriadeclare);
$objReader = PHPExcel_IOFactory::createReader($inputfiletype);
$objReader->setInputEncoding('ISO-8859-1');
utf8_encode($objReader);
$objPHPExcel = $objReader->load($pathgalleriadeclare);
} catch(Exception $e){
die('Error loading file "' .pathinfo($pathgalleriadeclare, PATHINFO_BASENAME).'": '.$e->getMessage());
}
$sheet = $objPHPExcel->getSheet(0);
$highRow = $sheet->getHighestRow();
$highColumn = $sheet->getHighestColumn();
for ($row = 7; $row <= $highRow; $row++){
//REPORT
$value = $objPHPExcel->getSheet(0)->getCell('A'.$row)->getValue();
echo $value ;
echo "<br />";
}
$objPHPExcel->disconnectWorksheets();
unset($objPHPExcel);
exit();
Here's a sample output:
I installed Excelbundle with PhpExcel library. I want to read excel files I found this function.
How can I use it? Any suggestion?
public function xlsAction()
{
$filenames = "your-file-name";
$phpExcelObject = $this->get('phpexcel')->createPHPExcelObject($filenames);
foreach ($phpExcelObject ->getWorksheetIterator() as $worksheet) {
echo 'Worksheet - ' , $worksheet->getTitle();
foreach ($worksheet->getRowIterator() as $row) {
echo ' Row number - ' , $row->getRowIndex();
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false); // Loop all cells, even if it is not set
foreach ($cellIterator as $cell) {
if (!is_null($cell)) {
echo ' Cell - ' , $cell->getCoordinate() , ' - ' , $cell->getCalculatedValue();
}
}
}
}
}
My suggestion is "Read the documentation" and start hacking at it. Working with excel is, in my experience, quite complex and time consuming so don't expect other people to solve your problem online.
It seems like you're talking about this bundle:
https://github.com/liuggio/ExcelBundle
It has great documentation, even full examples (see "Fake Controller").
With PHPExcel it is quite easy to read a Excel document.
See my example :
$dir = $this->getContainer()->getParameter("kernel.root_dir") . "/../../data/import/";
$file_name = "my_excel_file.xlsx";
$excel = $this->getContainer()->get('phpexcel')->createPHPExcelObject($dir . DIRECTORY_SEPARATOR . $file_name);
$sheet = $excel->getActiveSheet();
$row = 0;
while ($sheet->getCellByColumnAndRow(1, $row)->getValue()) {
$data = $sheet->getCellByColumnAndRow(2, $row)->getValue(); // get value from nth line and 2nf column
//do stuff -- see doc for functions on $sheet
}
I am trying to write mySQL data into Exlcel using PHPExcel, but I am getting file format is invalid in my above PHP code using PHPExcel. Can someone please help me to find out what is wrong in code:
$query = "SELECT company_id, userid FROM uam_user";
$result = mysql_query($query) or die ("Error in Query".mysql_error());
// Instantiate a new PHPExcel object
$objPHPExcel = new PHPExcel();
// Set document properties
$objPHPExcel->getProperties()->setCreator("Security Team")
->setLastModifiedBy("System")
->setTitle("System")
->setSubject("System Security")
->setDescription("Non Production user Upload Data")
->setKeywords("User Upload")
->setCategory("Security");
// Set the active Excel worksheet to sheet 0
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue("A1", 'company_id');
$objPHPExcel->getActiveSheet()->SetCellValue("B2", 'userid');
//start of printing column names as names of MySQL fields
$rowCount = 2;
//$num_rows = mysql_num_rows($result);
//echo $num_rows;
$i = 0;
while($row = mysql_fetch_array($result, MYSQL_ASSOC)){
if ($row['userid'] != '')
{
//echo "A$rowCount=".$row['company_id']."|B$rowCount=".$row['userid']."<br>";
$objPHPExcel->getActiveSheet()->SetCellValue("A$rowCount",$row['company_id']);
$objPHPExcel->getActiveSheet()->SetCellValue("B$rowCount",$row['userid']);
}
$rowCount++;
//echo $rowCount;
}
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="item_list.xlsx"');
header('Cache-Control: max-age=0');
ob_end_clean();
$objWriter->save ( 'php://output' );
I want to delete all rows that start with "//", from Excel sheet, with PHPExcel.
My code:
require '../Classes/PHPExcel.php';
require_once '../Classes/PHPExcel/IOFactory.php';
error_reporting(E_ALL & ~E_STRICT & ~E_NOTICE);
$path = "del_head.xls";
$objPHPExcel = PHPExcel_IOFactory::load($path);
$objWorksheet = $objPHPExcel->getActiveSheet();
$highestRow = $objWorksheet->getHighestRow();
$highestColumn = $objWorksheet->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
for($row=1; $row < $highestRow; ++$row){
$value = $objPHPExcel->getActiveSheet()->getCell('A'.$row)->getValue();
if (substr($value,0,2) == "//") {
$objPHPExcel->getActiveSheet()->removeRow($row, $row);
}
}
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel2007");
$objWriter->save($path);
But, the code not delete all rows that start with "//".
I think the problem is with function 'removeRow'.
Thank you very much in advance.
Replace this line
$objPHPExcel->getActiveSheet()->removeRow($row, $row);
with
$objPHPExcel->getActiveSheet()->removeRow($row);
There's one obvious problem with your call to removeRow(): The first argument is the starting row, the second is the number of rows to remove; so if you find a // at row 5, then you're telling PHPExcel to remove 5 rows starting from row 5 (i.e. rows 5 to 9).
You're also reading a file with a .xls extension (assuming that it's a BIFF file from the extension), but saving with the same .xls filename as an OfficeOpenXML file (which is normally a .xlsx file).
So what format actually is your file? What does a call to the IOFactory's identify() method recognise it as? If it's actually a comma- or tab-separated value file (most likely to have a leading //), then you'd be better using PHP's fgetcsv() and fputcsv() functions to process it to remove those lines.
Try this code, Its worked me
$filename = 'path/example.xls';
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load($filename);
$objWorksheet = $objPHPExcel->getActiveSheet();
$row_id = 1; // deleted row id
$number_rows = 2; // number of rows count
if ($objWorksheet != NULL) {
if ($objWorksheet->removeRow($row_id, $number_rows)) {
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save($filename);
}
}
Please, check the value assigned on line:
$highestRow = $objWorksheet->getHighestRow();
I've tested this code and the value is always 1
I am trying to rename upload filenames match the Post Title.
This other thread shows how to rename to hash:
Rename files during upload within Wordpress backend
Using this code:
function make_filename_hash($filename) {
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
$name = basename($filename, $ext);
return md5($name) . $ext;
}
add_filter('sanitize_file_name', 'make_filename_hash', 10);
Does anyone know the code to rename the file to match Post Title.extension?
barakadam's answer is almost correct, just a little correction based on the comment I left below his answer.
function new_filename($filename, $filename_raw) {
global $post;
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
$new = $post->post_title . $ext;
// the if is to make sure the script goes into an indefinate loop
if( $new != $filename_raw ) {
$new = sanitize_file_name( $new );
}
return $new;
}
add_filter('sanitize_file_name', 'new_filename', 10, 2);
Explanation of code:
Lets assume you upload a file with the original filename called picture one.jpg to a post called "My Holiday in Paris/London".
When you upload a file, WordPress removes special characters from the original filename using the sanitize_file_name() function.
Right at the bottom of the function is where the filter is.
// line 854 of wp-includes/formatting.php
return apply_filters('sanitize_file_name', $filename, $filename_raw);
At this point, $filename would be picture-one.jpg. Because we used add_filter(), our new_filename() function will be called with $filename as picture-one.jpg and $filename_raw as picture one.jpg.
Our new_filename() function then replaces the filename with the post title with the original extension appended. If we stop here, the new filename $new would end up being My Holiday in Paris/London.jpg which all of us know is an invalid filename.
Here is when we call the sanitize_file_name function again. Note the conditional statement there. Since $new != $filename_raw at this point, it tries to sanitize the filename again.
sanitize_file_name() will be called and at the end of the function, $filename would be My-Holiday-in-Paris-London.jpg while $filename_raw would still be My Holiday in Paris/London.jpg. Because of the apply_filters(), our new_filename() function runs again. But this time, because $new == $filename_raw, thats where it ends.
And My-Holiday-in-Paris-London.jpg is finally returned.
Something like this? (considering $post is your post variable, make it global):
function new_filename($filename) {
global $post;
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
return $post->post_title . $ext;
}
add_filter('sanitize_file_name', 'new_filename', 10);
Did I understand you?
