Trying to show a single blog post - El Forum - 05-20-2010
[eluser]kaos78414[/eluser]
So for practice I'm trying to create a blog with commenting functions and AJAX and all the normal stuff.
The problem I ran into, is I can't seem to pull a single entry for viewing. I have the entries truncated on the first page with a read more link, to bring them into full view.
This is the code for in the controller for viewing a blog entry:
Code:
function view() {
$data['post'] = $this->blogmodel->get_view();
$data['content'] = 'postview';
$this->load->view('includes/template', $data);
}And this is in the model:
Code:
function get_view(){
$this->db->where('blogId', $this->uri->segment(3));
$query = $this->db->get('blogposts');
if ($query->num_rows() == 1) {
return $query->row();
}
return FALSE;
}And the view has:
Code:
<div id="post">
<div id="post-title">
<?php echo $post->blogTitle; ?>
</div>
<div id="post-body">
<?php echo $post->blogBody; ?>
</div>
</div>I've done some tutorials, but I just can't seem to see what I'm doing wrong here. Can anyone enlighten me?

Btw, the error I get says that the problem is in the view:
A PHP Error was encountered
Severity: Notice
Message: Trying to get property of non-object
Filename: views/postview.php
Line Number: 3
And also line number 6, same error. Any help is appreciated

I found part of the problem, the URI segment isn't getting passed correctly for some reason. If I change $this->uri->segment(3) to $this->uri->segment(3, 1), it passes 1 and the blog with the id 1 shows up correctly.
So the uri segment is passing FALSE to the view, which is a non-object. I'm not sure why this is happening.

Further investigation:
It's not my .htaccess file.
There are no syntax errors. The url segment simply isn't getting passed to the model. I can't figure out why. Does anyone have any idea why this is happening? I've autoloaded the correct libraries and helpers. I don't see what could be causing this issue.
EDIT: Changing the code around, i moved the segment call to the function in the controller, passing it as a variable to the function in the view. This produces the same result. Any ideas?

Try approaching it as an array. The error states the $post var is not an object.

You can also put
Code:
print_r($post);If it says false, you now there is nowt data in it.

How exactly do I do that? The $post var should be returning $this->uri->segment(3). How do I list that as an array?
print_r($post); shows nothing at all.

Make sure you're not loading the url library twice... If you load it more than once, the url information is lost.

How about if you change your code like this:
Controller:
Code:
function view($blog_id = FALSE) {
if (!$blog_id)
{
return FALSE;
}
$data['post'] = $this->blogmodel->get_view($blog_id);
if (!$data['post'])
{
// Maybe check the $data['post'] here and load a error view for non existing blogid
$this->load->view('error');
return FALSE;
}
$data['content'] = 'postview';
$this->load->view('includes/template', $data);
}and the model:
Code:
function get_view($blog_id){
$this->db->where('blogId', $blog_id);
$query = $this->db->get('blogposts');
if ($query->num_rows() == 1) {
return $query->row();
}
return FALSE;
}As you see I removed using of $this->uri->segment(3). You can get the blogid just by adding it as a parameter to view method.
