I created this block for use in a commercial guide I'm doing and I'll share with you . As the search for answers , always enter the field content before of sidebar 1 and 2 in mobile and tablet devices , I created this custom mainbody block so I can put the categories in sidebar 1 and search filter in sidebar 2 . And when access is made of phones and tablets , these fields (sidebar 1 and 2 ) appear at the top of the mainbody , before content field (which returns the search results ) . Go templates \ t3_bs3_blank \ tpls \ blocks \ mainbody folder , and create a new file in this location . Name "two- sidebar- p " .

Now copy this code into " two - sidebar- p "

Access now

templates \ t3_bs3_blank \ tpls \ blocks \ and create a copy of mainbody file by the name " mainbody - p " and replace the line

$ this - > loadBlock ( ' mainbody / two - sidebar ', array ( ' sidebar1 ' = > $ sidebar1 , ' sidebar2 ' = > $ sidebar2 ) ) ;

by

$ this - > loadBlock ( ' mainbody / two - sidebar- p ', array ( ' sidebar1 ' = > $ sidebar1 , ' sidebar2 ' = > $ sidebar2 ) ) ;



To finish create a copy of the default theme and give the " default- p " name or the name you want . Open this theme ( default- p or the name you gave ) and in line

< ? php $ this - > loadBlock ( ' mainbody ' ) >

exchange for

< ? php $ this - > loadBlock ( ' mainbody - p' ) >
