$_SESSION['flash']['notice']; message not displaying

[surreal5335]

I have created a database that will allow users to create posts and currently see all the posts that have been created so far.

 

My problem is I have a message meant to display after creating a post that will dissapear when page is refreshed. As of now though that message is not displaying at all. The code used to set the message is:

 

function flash_notice($msg) {

if (!$msg) { return false; }

$_SESSION['flash']['notice'] = $msg;

return true;
}

 

which is well actually set here on another file:

 

if(create_post ($params['post'])) {
	flash_notice('Successfully created post!');
	redirect_to('controller_posts.php/');
}

 

the problem I am having is that my syntax:

 

$_SESSION['flash']['notice'] = '';

 

is still being executed despite my function that occurs before the last piece of code I just shown:

 

function redirect_to($address) {

header('location:'.WEBSITE.APP_ROOT.$address);
exit;

}

 

All this data is finally displayed to the user with this:

 

<?php if($_SESSION['flash']['notice']): ?>

	<span class="notice">
		<?php echo $_SESSION['flash']['notice']; ?>
	</span> 

<?php endif; ?>

 

If I enter a string into:

 

$_SESSION['flash']['notice'] = '';

 

It will print out fine. But its purpose is to set the string to blank, so it will make the other message dissapear upon a page refresh. From what I have been learning the exit; function allows the code to stop there so the code below it will not execute. But so far, it is executing just fine. Could someone tell me how I can go about fixing this?

 

I appreciate the help

For me it seems that you clear the flash notice too quick. You should clear it on another page, AFTER the redirect and AFTER you display it:

 

1. Set a flash message.

2. Redirect to another page.

3. Display it.

4. Clear.

 

In my code I wrote a class, which has two basic methods:

 

1. setMessage() - sets a message and performs an immediate redirect.

2. getMessage() - reads the message from a session, saves into an internal class field and resets the session data.

 

So I clear the message right after the first read. If I need to display it twice on the same page, it is still stored in the flash message object.

Thanks for the suggestion, would you happen to have a good article explaining setters and getters for php? I am having a hard time finding a good tutorial explaining it.

 

Also is it possible to check if an element has been echoed?

 

Thanks a lot for the help

well I decided I would try another way to go abou this problem using a suggestion you made.  I will make a temp detour to a page telling them creation of post has been made.  then redirect to a page with all the posts made so far.

 

My problem is I am having a trouble using set_time_limit()... I am not sure how to fire a redirect upon time out.

 

Here is my code so far:

 

include_once('config.php');
<?php
echo 'Successfully created post!<br/><br/>';

echo 'you will be automatically redirected in a few seconds.';

set_time_limit(5) 
?>

 

I appreciate your help

Such redirecting should be done with HTML. You cannot fire a redirect once you sent some HTML code - this is how the HTTP protocol works. First, you send headers, then the content. Once the browser starts displaying it, the PHP script has already stopped working. And a server redirect is a header.

 

<meta http-equiv="refresh" content="5;url=page.php">

 

The use of setters and getters can be found in every good object-oriented programming course.
