 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

22 $ This -> Load-> Library ('phpexcel/iofactory ');
23
24 $ Objphpexcel = New Phpexcel ();
25 $ Objphpexcel -> Getproperties ()-> settitle ("Export")-> setdescription ("NONE ");
26
27 $ Objphpexcel -> Setactivesheetindex (0 );

33 {
34 $ Objphpexcel -> Getactivesheet ()-> setcellvaluebycolumnandrow ( $ Col , 1, $ Field );

52 $ Objphpexcel -> Setactivesheetindex (0 );
