Download link

mariyanandh

I am using server side processing, I need one column with image indicating downloadable, once the link is selected, I want to make to process download.

How to implement this? please help me.

How would you do it without DataTables? I think the same process would apply. Typically you would just have a link to a script which will generate the download for you.

I've done something similar to this, with a "delete row" image/link, using fnRender.

in my db call, I create an extra column (any field will do, I use the ID field a second time) and for that column use fnRender to create the link using an image.

[code]
"aoColumns": [
// ... some other columns first
{
"sName": "id",
"sWidth": 30,
fnRender: function(oObj) {
var id = oObj.aData[0];

return "";
},
"bSortable": false,
"bSearchable": false
},
// ... some other columns after
[/code]

fnRender passes one arg: oObj, which has goodies like the row number, column number, and an array of the entire row's data. (see http://www.datatables.net/ref) in my case, I'm deleting based on the ID, which is in position 0 in the data array.

Your function must return a string; this becomes the HTML of your cell.

qapub_delete.php is my deletion script on server side. in your case, the href will be whatever download resource you intend. graphics/delete.png is my image.

oObj has these parts:
- int:iDataRow - the row in aoData
- int:iDataColumn - the column in question
- array:aData - the data for the row in question
- object:oSettings - the settings object for this DataTables instance
