PHP Array Error??

[aleister1987]

Hello all,

 

I have just downloaded a home banner module for opencart and after trying to get in touch with the original author, it looks like his not supporting his work correctly and im stuck with TWO PHP errors.

 

Warning: Invalid argument supplied for foreach() on line 22. Warning: array_multisort() [function.array-multisort]: Argument #1 is expected to be an array or a sort flag on line 25.

 

The code is as follows:-

 

<?php
/*
Homepage Slideshow v1.0
Brought to you by Readyman - www.alreadymade.com
*/

class ControllerModuleHomepageslideshow extends Controller {

protected function index() {
	//$this->language->load('module/homepageslideshow');
    	//$this->data['heading_title'] = $this->language->get('heading_title');
	//$this->load->model('tool/seo_url');

        $this->data['config_url'] = $this->config->get('config_url');
        $this->data['delay'] = $this->config->get('homepageslideshow_delay');
        $this->data['speed'] = $this->config->get('homepageslideshow_speed');
        $this->data['pause'] = $this->config->get('homepageslideshow_pause');
        $this->data['height'] = $this->config->get('homepageslideshow_height');
        $this->data['width'] = $this->config->get('homepageslideshow_width');

        $a = unserialize($this->config->get('homepageslideshow_slide_image'));
        foreach ($a as $key => $row) {
            $sorting[$key]  = $row['sortorder'];
        }
        array_multisort($sorting, SORT_ASC, $a);
        $this->data['slide_images'] = $a;
	$this->id = 'homepageslideshow';

	if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/module/homepageslideshow.tpl')) {
		$this->template = $this->config->get('config_template') . '/template/module/homepageslideshow.tpl';
	} else {
		$this->template = 'default/template/module/homepageslideshow.tpl';
	}

	$this->render();
    }



}

 

 

any help would be greatly appreciated!!

The error is stemming from this:

$a = unserialize($this->config->get('homepageslideshow_slide_image'));

 

Either the return values for that function are not serialized or is empty/false.  Try echo'ing/dumping the results to see what's being returned.

Thanks for the reply! Is there anyway i could remove that or simply change the way its written. The actual application itself works. I think they are just warning errors.

 

How would you go about changing that function?

 

I'm not hot on PHP, that's why i have posted lol.

 

An help would be great!

Sure you could.  Where do your images come from?

[aleister1987]

My images come from a directory, im sure it's ../catalog/view/theme/default/image/

 

That's where the slides for the slideshow are placed and used.

Could i attach a zip file with all the files relating to that file?

Just to show you where the scripts are coming and going to?
