Does anyone have an idea to create the dynamic form with uploaded excel file.
We need to facilitate users to add data in the pre-uploaded file. Can anyone help with this? We are doing in this way:
$objPHPExcelWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,'HTML');
$objPHPExcelWriter->save('php://output');
But this above code only displays structure of excel on the web still we're unable to edit it.
you will need 2 pear packages
PHP-ExcelReader package
Spreadsheet_Excel_Writer package
What you need to do is read first the excel file use PHP-ExcelReader package It reads the binary format of XLS files directly and can return values and formats from any cell. http://code.google.com/p/php-excel-reader/
read the excel file
$data = new Spreadsheet_Excel_Reader("test.xls");
show the data of the file
$data->dump($row_numbers=false,$col_letters=false,$sheet=0,$table_class='excel')
Once you have stored the data in a variable save the data in another file this time you will use the The Spreadsheet_Excel_Writer package https://github.com/pear/Spreadsheet_Excel_Writer
<?php
require_once 'Spreadsheet/Excel/Writer.php';
$workbook = new Spreadsheet_Excel_Writer('test.xls');
$worksheet =& $workbook->addWorksheet('My first worksheet');
if (PEAR::isError($worksheet)) {
die($worksheet->getMessage());
}
$workbook->close();
?>

I am using PHPExcel to validate csv files before parsing them and storing in my database and server. I am trying to use the file properties to determine if the file has been modified or if it is the original file. I have used the following for .xls, .xlsx with great results (using the appropriate reader);
$file = $_FILES['file']['tmp_name'];
$reader = new PHPExcel_Reader_CSV();
if($reader->canRead($file)){
$object = $reader->load($file);
$created = $object->getProperties()->getCreated();
$modified = $object->getProperties()->getModified();
if(!$created===$modified){
//File has been edited and cannot be used
}else{
//File is good, continue processing
}
}
However, when using CSV files, NOTHING is working as expected. I renamed an MS-Word doc to .csv->passed, edited a csv->passed, even used a .jpg->passed. What on earth am I missing?? Any help would greatly appreciated! Edit->I should note that $created and $modifed are an exact match when var_dump($object) despite having edited the file and confirming the changes within the document properties.
The properties values accessible from PHPExcel are those stored within the file itself, not within the directory entries for that file.
CSV files don't have any inherent properties of their own; CSV is purely a raw data file format These property methods are for accessing the properties that do exist in other spreadsheet formats such as BIFF (xls) and OfficeOpenXML (xlsx) which do support them. Loading a CSV (or other format that doesn't support properties) into PHPExcel will provide default value for those properties (so that calls like you're making won't trigger fatal errors), but it cannot provide actual values for something that doesn't natively exist in the format being loaded.
I am using simplexlsx to read xlsx sheet,
I have multiple tabs in my xlsx file, When I am trying to read data, its shows data only for first tab,
for better understanding i have attach print screen.
Try This,
$this->load->library('simplexlsx');
$xlsx = new SimpleXLSX( $file_path );
$data['csv_data'] = $xlsx->rows();
It is because when you select something from an excel file it performs that action with the active sheet which is by default is the first one.
You need to change that to the required sheet
Use the following code to do that
$objPHPExcel->setActiveSheetIndex($count); // Use no of the sheet you want to select -1 as count
I wanted to append data in the pre formated excel sheet that is basically header footer in the excel sheet I wanted to append the contents. And will create many files dynamically.
A simple workaround is:
create a html table with the formatting you need
add values in php to the table (or generate table with php)
save file as .xls (filled with content from html table)
open file (will show formatted table in Excel)
Reason:
handling XLS files is very complex and many libraries have big limits (only available on windows servers....)
html table saved as .xls can be opened in Excel.
Thanks I have found the way PHPExcel is a good library.
In order to get PHPExcel http://www.codeplex.com/PHPExcel working with CodeIgniter, there are a few steps you must take to ensure compatibility with CodeIgniter's naming standards.
1: Class names must match the file names. PHPExcel has a few files(such as PHPExcel/IOFactory.php) that have names like PHPExcel_IOFactory. Change these names by removing the "PHPExcel_" part. These constructors in these files must be public in order for CI to access them.
$this->load->library('phpexcel');
$this->load->library('PHPExcel/iofactory');
$objPHPExcel = new PHPExcel();
$objPHPExcel->getProperties()->setTitle("title")
->setDescription("description");
// Assign cell values
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'cell value here');
// Save it as an excel 2003 file
$objWriter = IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save("nameoffile.xls");
I have a file in xls format that I need to refresh (use 'refresh all' button in Excel) once a day and then retrieve the data from the pivot table and inset them into the database (MySQL). The file gets data from an external source (retrieve data from sharepoint 2007).
How is the easiest way to do this?
I'm thinking abaout PHP but do I not quite know how you go about it. From what I read PHPExcel does not support this operations.
When you try to use COM I get an error:
Fatal error: in D:\xampp\htdocs\sp\xls\index.php on line 11
And here is a php code:
<?php
// Start Excel
$excel = new COM("Excel.Application") or die ("Could not load Excel.Application");
// Make Excel visible.
$excel->Application->Visible = 1;
// Open workbook
$Workbook = $excel->Workbooks->Open('D:/xampp/htdocs/sp/xls/emails.xls', 'r+') ;
// Refresh all
$Workbook->RefreshAll();
// Save updated excel file out to disk somewhere
$Workbook->SaveAs('D:/xampp/htdocs/sp/xls/emails.xls');
// Close all instances of excel:
$Workbook->Close(false);
unset($Workbook);
$excel->Workbooks->Close();
$excel->Quit();
unset($excel);
?>
I'm using windows 7 and xampp with php 5.5.6
In php.ini I've added this line:
extension=php_com_dotnet.dll
Alternate: is it possible to run *.iqy file generated by sharepoint in php?
I found a workaround to my problem.
Instead, refresh the data by PHP pointed out in a query that collects data during the re-launch of the sheet. To this I added this VBA script save changes and close file.
At the end of the added task scheduler to run the sheet once per day.
The rest of downloading data from Excel using PHPExcel.
I have a excel i need to add some more sheets into the excel using PHP, i have used PEAR, there i tried only can write excel and read a file, not able to read and modify the file, guys can you help me in this?
Thanks in advance
