Pipeline & POST

elmezie

It seems that currently when your using the pipeline feature that it uses $_GET .
$_GET is not available for use on my server . Is there a way to use pipeline with POST?

I know that you have to use .post instead of getJson , but after that. i get confused

Ok, figured it out.

For anyone wondering.

in the function fnDataTablesPipeline

change

$.getJSON( sSource, aoData, function (json) {
/* Callback processing */
oCache.lastJson = jQuery.extend(true, {}, json);

if ( oCache.iCacheLower != oCache.iDisplayStart )
{
json.aaData.splice( 0, oCache.iDisplayStart-oCache.iCacheLower );
}
json.aaData.splice( oCache.iDisplayLength, json.aaData.length );

fnCallback(json)
} );

TO

jQuery.post( sSource, aoData, function (data) {
/* Callback processing */
oCache.lastJson = jQuery.extend(true, {}, data);

if ( oCache.iCacheLower != oCache.iDisplayStart )
{
data.aaData.splice( 0, oCache.iDisplayStart-oCache.iCacheLower );
}
data.aaData.splice( oCache.iDisplayLength, data.aaData.length );

fnCallback(data)
},"json" );


This appears to work. Basically its saying instead of using GET use POST and then return the POST data as json

Allan, is there a way to cache all previously viewed pages?

Hi elmezie,

There isn't a method of doing that at the moment - but there is no reason why the pipelining method couldn't be modified to do that if you feel like a hack :-). You'd need to ensure that all the variables match exactly as before (length, sorting, filtering etc) before returning results from the cache, but it would certainly be possible.

Please take a look at this question http://datatables.net/forums/discussion/9878/server-side-processing-with-pipelining
