Export data from codeigniter + phpexcel to an Excel file

1. Preparations

Download phpexcel: http://phpexcel.codeplex.com

This is a powerful Excel database. Only the Excel file export function is demonstrated here. Most of the functions may not be needed.

2. Install phpexcel to codeigniter

1) decompress the contents in the classes folder of the compressed package to the Application \ libraries \ directory. The directory structure is as follows:

-- Application \ libraries \ phpexcel. php

-- Application \ libraries \ phpexcel (folder)

2) modify the application \ libraries \ phpexcel \ iofactory. php file

-- Change the class name from phpexcel_iofactory to iofactory and follow the CI class naming rules.

-- Change the constructor to public.

3. After the installation is complete, write a controller for exporting the Excel file)

CodeAs follows:

 1 <? PHP
 2  
 3   Class Table_export Extends Ci_controller {
 4   
 5       Function _ Construct ()
 6 {
 7 Parent: :__ construct ();
 8   
 9           //  Here you should add some sort of user validation
  10  // To prevent strangers from pulling your table data  
  11 }
 12   
 13       Function Index ( $ Table_name )
 14 {
 15           $ Query = $ This -> DB-> get ( $ Table_name );
16   
 17           If (! $ Query )
 18               Return   False ;
 19   
 20           //  Starting the phpexcel Library  
  21           $ This -> Load-> Library ('phpexcel ');
22           $ This -> Load-> Library ('phpexcel/iofactory ');
 23   
 24           $ Objphpexcel = New Phpexcel ();
 25           $ Objphpexcel -> Getproperties ()-> settitle ("Export")-> setdescription ("NONE ");
 26   
 27           $ Objphpexcel -> Setactivesheetindex (0 );
28   
 29           //  Field Names in the first row  
  30           $ Fields = $ Query -> List_fields ();
 31           $ Col = 0;
 32           Foreach ( $ Fields   As   $ Field )
 33 {
 34               $ Objphpexcel -> Getactivesheet ()-> setcellvaluebycolumnandrow ( $ Col , 1, $ Field );
 35               $ Col ++;
 36 }
 37   
 38           //  Fetching the table data 
  39           $ Row = 2;
 40           Foreach ( $ Query -> Result () As   $ Data )
 41 {
 42               $ Col = 0;
 43               Foreach ( $ Fields  As   $ Field )
 44 {
 45                   $ Objphpexcel -> Getactivesheet ()-> setcellvaluebycolumnandrow ( $ Col , $ Row , $ Data -> $ Field );
 46                   $ Col ++;
 47 }
48   
 49               $ Row ++;
 50 }
 51   
 52           $ Objphpexcel -> Setactivesheetindex (0 );
 53   
 54           $ Objwriter = Iofactory: createwriter ( $ Objphpexcel , 'Excel5 ');
 55   
56           //  Sending headers to force the user to download the file  
  57           Header ('Content-type: Application/vnd. MS-Excel ');
 58           Header ('Content-Disposition: attachment; filename = "products _'. Date ('Dmy').'.xls "');
 59           Header ('Cache-control: Max-age = 0 ');
 60   
61           $ Objwriter -> Save ('php: // output ');
 62 }
 63   
 64 }
