Display alert message and redirect after click on accept

Question

Well  I have a page with links to reports  Whenever somebody clicks on one report  they can download the excel file  However  sometimes there are no fields to make a report  in that case  I want to display an alert message and after they click on  accept   they get redirected to the main panel  When they click on the report  they go to a controller that uses a switch to get the data  If there s no data  the model returns FALSE  so at the end of the controller  I check   if   result array    FALSE      to excel  result array- gt result array     xls  campos   else       echo   lt script gt alert  There are no fields to generate a report    lt  script gt        redirect  admin ahm panel        If I get rid of redirect  admin ahm panel    then the alert works  but it moves the user to the page that was supposed to generate the excel file  But if I use the redirect  the controller moves the user to the main panel without showing the alert   Any help is appreciated   Thanks in advance

Combining CodeIgniter and JavaScript     for using the base url   function  this- gt load- gt helper  url     echo   lt script type  javascript text  gt    echo  alert  There are no fields to generate a report     echo  window location href        base url      admin ahm panel    echo   lt  script gt      Note  The redirect   function automatically includes the base url path that is why it wasn t required there

The redirect function cleans the output buffer and does a header  Location        redirection and exits script execution  The part you are trying to echo will never be outputted   You should either notify on the download page or notify on the page you redirect to about the missing data
