this- session- set flashdata and then this- session- flashdata doesn t work in codeigniter

Question

Please take a look at the following code    this- gt session- gt set flashdata  message    This is a message     var dump  this- gt session- gt flashdata  message       It returns bool false    I hope it doesn t NEED a redirect   to be recallable after that  because some times I need to call it right after setting the flashdata in a view     Edit after venkat s comment   this- gt session- gt set flashdata  message    This is a message      this- gt session- gt keep flashdata  message    var dump  this- gt session- gt flashdata  message       No difference unfortunately

Well  the documentation does actually state that     CodeIgniter supports  flashdata   or session data that will only be   available for the next server request  and are then automatically   cleared    as the very first thing  which obviusly means that you need to do a new server request  A redirect  a refresh  a link or some other mean to send the user to the next request   Why use flashdata if you are using it in the same request  anyway  You d might as well not use flashdata or use a regular session
