a simple way to just reload a current page.

[Tokae]

I have an html table that is being populated with links from a specific directory..

 

I would like the user to be able to click the link and if its a file they will download the file. If its a directory, I woudl like to reload the current page but this time show the contents of the directory.

 

My main issue is that I have a session variable called 'workingdirectory' that I need to update before I reload the page. I have tried setting it and then calling Location('page.php') but I get the 'cannot change header information' error. I realized I was getting this because I had begun to call HTML code before the PHP was finished. Is there a way to just simply update the session variable, and then make the page reload when the user clicks on a link?

Simple: don't use a session variable for it. Stick in the URL.

script.php?dir=foo/bar/baz

Be sure to validate it before you use it blindly.

Thank you,

 

That does the job! I was hoping to use a session though so the directories were not listed in URL. Is there a way to just reload the page after setting a session variable? I am just drawing a blank and admittedly not the best with php yet

 

I had my conditional line calling a function if a directory was found:

 

<a href=" <?php ChangeFolder($file) ?>"> directory name here</a>




<?php


function ChangeFolder($file)
{
      $_SESSION['workingfolder'] = $_SESSION['workingfolder']."/".$file;

     *** refresh page or reload page here***
}

?>

 

 

I just cant for the life of me figure out the simple way to reload the page :/

 

Once again thank you though for your solution..

Sessions are not for keeping things out of the URL. It's not what they're for. It's part of how they work and not why they work.

 

Nothing in the URL? Then use a POSTed form.

Solid copy!
