Flashdata boolean gets converted between requests

[eluser]mawe[/eluser]
Hi all!

The topic pretty much says it all. I have this in a controller:

Code:

function delete($news_id)
{
    if ($this->News_Model->delete($news_id) === TRUE)
    {
        $this->session->set_flashdata('deleted', TRUE);
    }
    else
    {
        $this->session->set_flashdata('deleted', FALSE);
    }

    redirect(base_url().'admin/news/archive', 'location');
}

In the archive view I had this:

Code:

<?php if ($this->session->flashdata('deleted')): ?>

<?php if ($this->session->flashdata('deleted') === TRUE): ?>
<p class="success">News gelöscht!</p>
&lt;?php else: ?&gt;
<p class="error">News konnte nicht gelöscht werden!</p>
&lt;?php endif; ?&gt;

&lt;?php endif; ?&gt;

The inner if (the one that checks for TRUE) doesn't work. I examined the session and the flashdata item is actually '1', a string, not boolean TRUE.

Is this expected behaviour?

I think this is expected
When the session data is stored, its serialized, so it all becomes a long String
When it gets deserialized at the other end, I'm asuming it was stored as '1', so it probably stays as that

Thanks for the answer, but this is only correct for the first part.
Just tested this on my machine. Though it really gets serialized to a string, unserialize handles data types properly:

Code:

C:\Users\MatiPati\Desktop>type test.php
<?php

$a = serialize(TRUE);
var_dump($a);
var_dump(unserialize($a));

?>

C:\Users\MatiPati\Desktop>php -f test.php
string(4) "b:1;"
bool(true)

What if you do it this way?

Code:

function delete($news_id)
{
    if ($this->News_Model->delete($news_id) === TRUE)
    {
        $this->session->set_flashdata('deleted', 1);
    }
    else
    {
        $this->session->set_flashdata('deleted', 0);
    }

    redirect(base_url().'admin/news/archive', 'location');
}

And in the view:

Code:

<?php if (isset($this->session->flashdata('deleted'))): ?>

<?php if ($this->session->flashdata('deleted')): ?>
<p class="success">News gelöscht!</p>
&lt;?php else: ?&gt;
<p class="error">News konnte nicht gelöscht werden!</p>
&lt;?php endif; ?&gt;

&lt;?php endif; ?&gt;

Maybe the synthax is broken somewhere (no code highlighting in the reply textarea)... But I hope this can help!
