I have problem

[eluser]ibnu drim[/eluser]
I’m sure this is something trivial but I’ve spent the last hour scratching my head on this one!

I have several functions in my Model that all look like this (that find various things):
this is my controller :
Code:
function post( $slug = FALSE )
    {
        if( empty( $slug ) )
            show_404();
            
        $this->load->model('model_posts');
        $this->load->model('model_gallery');
      //$posts = $this->model_gallery->getPosts();
        $posts = $this->model_gallery->getChild( $slug );
        
        $data = array(
            'contentPage'        =>    'gallery',
            'breadcrumb'        =>    $this->model_posts->createBreadCrumb(),
            'advTop'            =>  FALSE,
            'posts'             =>  $posts
        );
        
        ?>
        <pre>&lt;?php //echo print_r($posts); ?&gt;</pre>
        &lt;?php
        
        if( $posts )
        $data['show'] = $posts->title;
            
        $this->load->view('index', $data);
    }
this is my Model :
Code:
function getChild( $slug = FALSE )
    {
        $this->db->where('status', 1)
                 ->where('parent', 0)
                 ->where('slug', $slug)
                 ->from('gallery');
                
        $query = $this->db->get();
            
        $posts = array();
        foreach( $query->result() as $result )
        {
            $galler = array();
            
            #has Child?
            $child = $this->pagesHierarchy( $result->ID );
            if( $child )
            {
                foreach( $child->result() as $c )
                    $galler['child'][] = $c;
                    
            }    
                $galler['parent'] = $result;
                
                $posts[] = $galler ;
            
        }
        //return $posts ;
        return !count( $posts )? FALSE:$posts;
    }
    
    function pagesHierarchy( $idParent = FALSE )
    {
        if( !$idParent || empty( $idParent ) )
            return FALSE;
        
        $this->db->where('parent', $idParent)
                 ->from('gallery')
                 ->order_by('ID', 'ASC');
                
        $RES = $this->db->get();
        
        return $RES->num_rows() <= 0? FALSE:$RES;
    }

this is my View :
Code:
&lt;?php
    if( $posts ):
?&gt;
                    <table class="gallery-lists">
&lt;?php
        $count = 1; $tCount = 1;
        foreach( $posts as $post ):
            
            $primaryImg = $this->models->_unserialize( $post->image_primary );
            $secondaryImg = $this->models->_unserialize( $post->image_secondary );
            
            if( $count <= 1 ):
?&gt;                    
&lt;?php
            endif;
?&gt;
&lt;?php $slug = $post->slug ;
                                echo site_url( array('gallery', $slug ) ); ?&gt;

please help me solve this error.
Trying to get property of non-object & uninitialized string offset :0
Thank you

Is there any errors from PHP, or are you just not getting the expected result?
#3

[eluser]TheBaron[/eluser]
The first error is simple.

Code:
$foo = '';
$foo->boo;

It appears on a cursory scan that you are assigning your posts to an array. You are then treating that array like an object.

Code:
$post->title; // Wrong
$post['title'] // Correct

As for the second problem... I don't know where it is. Don't these errors have line numbers?

It is caused by using array syntax on a non-array... i.e.

Code:
$foo = '';
echo $foo[0];

Hopefully this should help you find the problems.

If the array you just posted is your $posts data, you're accessing the data incorrectly.

When you loop through it in your view via foreach, that single $post variable will contain this data structure:
Code:
Array
        (
            [child] => Array
                (
                    [0] => stdClass Object
                        (
                            [ID] => 6
                            [title] => test-child3
                            [content] =>
                            [excerpt] =>
                            [image_primary] => a:13:{s:9:"file_name";s:16:"banner_kiri1.jpg";s:9:"file_type";s:10:"image/jpeg";s:9:"file_path";s:49:"D:/Webxampp/xampp/htdocs/citralandkendari/upload/";s:9:"full_path";s:65:"D:/Webxampp/xampp/htdocs/citralandkendari/upload/banner_kiri1.jpg";s:8:"raw_name";s:12:"banner_kiri1";s:9:"orig_name";s:16:"banner_kiri1.jpg";s:8:"file_ext";s:4:".jpg";s:9:"file_size";s:5:"62.85";s:8:"is_image";s:1:"1";s:11:"image_width";s:3:"250";s:12:"image_height";s:3:"700";s:10:"image_type";s:4:"jpeg";s:14:"image_size_str";s:24:"width="250" height="700"";}
                            [image_secondary] =>
                            [article_post] => multiple
                            [slug] => test-child3
                            [is_dynamic] => 1
                            [allow_edit] => 1
                            [author] => 1
                            [author_modified] => 1
                            [parent] => 3
                            [status] => 1
                            [date_add] => 2011-06-23 15:09:48
                            [date_modified] => 2011-07-13 15:59:32
                        )

                )

            [parent] => stdClass Object
                (
                    [ID] => 3
                    [title] => test 3
                    [content] =>
                    [excerpt] =>
                    [image_primary] => a:13:{s:9:"file_name";s:16:"banner_kiri1.jpg";s:9:"file_type";s:10:"image/jpeg";s:9:"file_path";s:49:"D:/Webxampp/xampp/htdocs/citralandkendari/upload/";s:9:"full_path";s:65:"D:/Webxampp/xampp/htdocs/citralandkendari/upload/banner_kiri1.jpg";s:8:"raw_name";s:12:"banner_kiri1";s:9:"orig_name";s:16:"banner_kiri1.jpg";s:8:"file_ext";s:4:".jpg";s:9:"file_size";s:5:"62.85";s:8:"is_image";s:1:"1";s:11:"image_width";s:3:"250";s:12:"image_height";s:3:"700";s:10:"image_type";s:4:"jpeg";s:14:"image_size_str";s:24:"width="250" height="700"";}
                    [image_secondary] =>
                    [article_post] => multiple
                    [slug] => test-3
                    [is_dynamic] => 0
                    [allow_edit] => 1
                    [author] => 1
                    [author_modified] => 1
                    [parent] => 0
                    [status] => 1
                    [date_add] => 2011-06-05 16:02:24
                    [date_modified] => 2011-07-13 18:24:29
                )

        )

If you are trying to access the parent data, you'll need to do so like this:
Code:
$post['parent']->title;
$post['parent']->image_primary;
