[Solved] Trouble with Grid Paging and additional params

[amegahed]

Im using a php page which has all my queries based on a queryid that i pass to it. this is how i load the store the first time:

 dsMovies.load({params:{start: 0, limit: 25, queryid: 201}});

and this is my store:

 var dsMovies = new Ext.data.JsonStore({
  totalProperty : 'total', 
  root   : 'results', 
  url    : 'php/myqueries.php',  
  fields   : [
   {name: 'movieid', type: 'int'},
   'moviename', 'moviegenre', 'movieyear', 'movieoutline', 'movieplot', 'movieimdbid', 'movieposter', 
   'moviedirector', 'movierating'
  ]
 });

and this is the pagingtoolbar

var pbarMovies = new Ext.PagingToolbar({
 pageSize: 25,
 store: dsMovies,
 displayInfo: true,
 displayMsg: 'Displaying {0} - {1} of {2}',
 emptyMsg: "No Movies to display"
});

when the page loads, i can see from firebug that the posted params are:

limit 25
queryid 201
start 0

but when i press the next button on the paging toolbar this the params that are sent (seen from firebug)

limit 25
start 25

and i get no results back? any thoughts?

I reverted to the old way i had my queries setup, using the GET:

 var dsMovies = new Ext.data.JsonStore({
  totalProperty : 'total', 
  root   : 'results', 
  url    : 'php/myqueries.php?queryid=201',  
  method   : 'post',
  fields   : [
   {name: 'movieid', type: 'int'},
   'moviename', 'moviegenre', 'movieyear', 'movieoutline', 'movieplot', 'movieimdbid', 'movieposter', 
   'moviedirector', 'movierating'
  ]
 });

and if i need to change the queryid i use:

dsMovies.proxy.conn.url = 'php/myqueries.php?queryid=702';  
dsMovies.load({params:{start: 0, limit: 25, var1: el.getValue()}});

which works.. but i still would like to know how can i make it work using POST

Look at baseParams, setBaseParam() in JsonStore API

See Grid FAQ section on sending additional data with baseParams. setBaseParam() is new to 3.0, I don't think it is mentioned in Grid FAQ.

That is very funny I read about baseParams during my search and i already tried it earlier today, but for some reason it did not work but i thought now that you mentioned it, maybe i should give it another try.. and it worked

var dsMovies = new Ext.data.JsonStore({
  totalProperty : 'total', 
  root   : 'results', 
  url    : 'php/myqueries.php',  
  baseParams  : { queryid: 201},
  method   : 'post',
  fields   : [
   {name: 'movieid', type: 'int'},
   'moviename', 'moviegenre', 'movieyear', 'movieoutline', 'movieplot', 'movieimdbid', 'movieposter', 
   'moviedirector', 'movierating'
  ]
 });
