How grouping rows by field in PHPExcel - php

Question

I have a problem when creating excel files with the phpExcel library.
I want to create groups on certain lines based on the sales column (with same sales name).
I have made the file manually by using the Subtotal feature on the Data tab in Excel.
Is it possible that phpexcel has such feature?
You can see the sample file that I mean on the link / image that I uploaded.

Answer 1

You can group the rows like this
$objPHPExcel->getActiveSheet()->getRowDimension('5')->setOutlineLevel(1);
For more details you can visit here.
You can also go here and here for working examples

Answer 2

Using the PHPExcel , you can use the methods :
setOutlineLevel($level) // the level of the current row
setVisible(false) // show or hide the group
setCollapsed(true) // add collapse to group (as figure out in the picture above )
THe point here is to define group condition , example :
We suppose that the file excel is already generated with PHPExcel and
now you are going to read the file again for grouping rows .
First let's read the column C that contain name of salesman and store them inside the $salemans :
$salesmans = array();
/*
the output of $salesmans seems to be something like :
[0] ==> "Abdul Karim",
[1] ==> "Apan Total",
[2] ==> ""Ari Total
*/
The array $salesman should have distinct value , so when trying to
insert inside the array verify if the current value doesn't exist
already in the $salesmans.
Example :
$salesmans=array();
if (!in_array($currentSalesman, $salesmans))
{
$array[] = $value;
}
Here , we are going to to set the level of each row by getting the value of the current salesman with the key in the $salesmans
Caution : please try to modify this section because i'm not getting
how you manage fetch rows.I'm just making code more clear to understand easy
for ($row = 0; $row <= 10000; ++$row) {
$currentsalesman = $row['c']; //
$keylevel = array_search($currentsalesman, $salesmans);// this will return the key in $salesmans array
$objPHPExcel->getActiveSheet()
->getRowDimension($row)
->setOutlineLevel($keylevel) // set here the level .
->setVisible(false)
->setCollapsed(true);
}
