In Laravel the best way to pass different types of flash messages in the session

Question

I m making my first app in Laravel and am trying to get my head around the session flash messages  As far as I m aware in my controller action I can set a flash message either by going  Redirect  to  users login  - gt with  message    Thanks for registering       is this actually OK    For the case of redirecting to another route  or  Session  flash  message    This is a message        In my master blade template I d then have    if Session  has  message     lt p class  alert alert-info  gt    Session  get  message      lt  p gt   endif   As you may have noticed I m using Bootstrap 3 in my app and would like to make use of the different message classes  alert-info  alert-warning  alert-danger etc   Assuming that in my controller I know what type of message I m setting  what s the best way to pass and display it in the view  Should I set a separate message in the session for each type  e g  Session  flash  message danger    This is a nasty message  Something s wrong       Then I d need a separate if statement for each message in my blade template   Any advice appreciated

One solution would be to flash two variables into the session:

The message itself
The "class" of your alert

for example:

Session::flash('message', 'This is a message!'); 
Session::flash('alert-class', 'alert-danger');

Then in your view:

@if(Session::has('message'))
<p class="alert {{ Session::get('alert-class', 'alert-info') }}">{{ Session::get('message') }}</p>
@endif

Note I've put a default value into the Session::get(). that way you only need to override it if the warning should be something other than the alert-info class.

(that is a quick example, and untested :) )

Simply return with the  flag  that you want to be treated without using any additional user function  The Controller   return  Redirect  back  - gt withSuccess   Message you want show in View       Notice that I used the  Success  flag   The View    if  Session  has   success             Session  get   success        elseif  Session  has   warning             Session  get   warning        lt  -- here to  withWarning    -- gt   endif   Yes  it really works

In your view    lt div class  flash-message  gt     foreach    danger    warning    success    info   as  msg       if Session  has  alert-     msg        lt p class  alert alert-    msg     gt    Session  get  alert-     msg     lt  p gt       endif    endforeach  lt  div gt    Then set a flash message in the controller   Session  flash  alert-danger    danger    Session  flash  alert-warning    warning    Session  flash  alert-success    success    Session  flash  alert-info    info

I think the following would work well with lesser line of codes           session  - gt flash  toast              status    gt   success             body    gt   Body            topic    gt   Success            I m using a toaster package  but you can have something like this in your view                toastr   session  toast status                       session  toast body                         session  toast topic

Not a big fan of the solutions provided  ie  multiple variables  helper classes  looping through  possibly existing variables    Below is a solution that instead uses an array as opposed to two separate variables  It s also easily extendable to handle multiple errors should you wish but for simplicity  I ve kept it to one flash message   Redirect with flash message array       return redirect   admin permissions  - gt with  flash message     success   Updated Successfully   Permission      permission- gt name     updated successfully        Output based on array content    if Session  has  flash message         lt script type  text javascript  gt          jQuery document  ready function                bootstrapNotify    session  flash message   0        session  flash message   1        session  flash message   2                        lt  script gt   endif   Unrelated since you might have your own notification method plugin - but just for clarity - bootstrapNotify is just to initiate bootstrap-notify from http   bootstrap-notify remabledesigns com    function bootstrapNotify type title    Notification  message        switch  type            case  success               icon    la-check-circle               break          case  danger               icon    la-times-circle               break          case  warning               icon    la-exclamation-circle                notify  message  message  title   title  icon    icon la    icon    type  type allow dismiss  true newest on top  false mouse over  true showProgressbar  false spacing  10 timer  4000 placement   from   top  align   right   offset   x  30 y  30  delay  1000 z index  10000 animate   enter   animated bounce  exit   animated fadeOut

If you want to use Bootstrap Alert to make your view more interactive  You can do something like this  In your function - if  author- gt save         Session  flash  message    Author has been successfully added        Session  flash  class    success      you can replace success by  info warning danger      return redirect  main successlogin     In your views -  if Session  has  message         lt div class  quot alert alert-  Session  get  class     alert-dismissible fade show w-50 ml-auto alert-custom quot          role  quot alert quot  gt             Session  get  message               lt button type  quot button quot  class  quot close quot  data-dismiss  quot alert quot  aria-label  quot Close quot  gt               lt span aria-hidden  quot true quot  gt  amp times  lt  span gt           lt  button gt       lt  div gt   endif
