passing array to views

[eluser]emsurban[/eluser]
can any help me figure out the problem in this code. What I would like to do is pass a file list to views.

controller code:

Code:

$path = base_url().'/images/';
    $data['images'] = get_filenames($path,TRUE);
  
    $this->load->view('gallery_view',$data);

views code:

Code:

<?php foreach($images as $image):?>

<?php echo $image; ?>

<?php endforeach;?>

I got this error

Message: Invalid argument supplied for foreach()

Can any help me, i'm a newbie to CI. Thanks in advance.

get_filenames returns a boolean (FALSE) if the opendir command fails, and a boolean is not valid for a foreach loop
To see if this is the case, to a var_dump/print_r on what it returns

The problem is $data['images'] is not an array so that you can not use foreach()
Try:

Code:

$data['images'][] = get_filenames($path,TRUE);

true , so you could do this in the view to see if the function returns a FALSE or an array

Code:

<?
    if( is_array( $images ) )
    {
        //<pre> tag it's only to make the array structure more readeable
        echo '<pre>'.print_r( $images , true ) .'</pre>';
    }
    else
    {
        echo 'NO IMAGES ( FALSE ) ';
    }
?&gt;

Saludos.

This can be done in the view but as a personal preference I would rather check the array in the controller and if it is FALSE then pass an empty array to the view. This way the foreach will still find an array but will not actually do anything because there is no data to handle.

true, if you pass an empty array, the code will look like this.

Code:

<?
    // IN THE CONTROLLER
    $path   = base_url().'/images/';
    $images = get_filenames($path,TRUE) ;
    $data['images'] = ( is_array( $images ) ) ? $images : array() ;

    // IN THE VIEW
    if( count( $images ) > 0 )
    {
        //<pre> tag it's only to make the array structure more readeable
        echo '<pre>'.print_r( $images , true ) .'</pre>';
    }
    else
    {
        echo 'NO IMAGES ( EMPTY ARRAY ) ';
    }
