hello ,

i'm experimenting with codeigniter and grocery crud as well as with diffrent codeigniter admin templates. I am  trying to use grocery crud in an admin area (I have used the template .ark AdminPanel for Codigniter Bootstrap : Devzone.co.in) and specifically in one of the navigation links(tables) to handle deleting and editing clients. The problem is that when I am trying to add the content of the example.php(views) file into another view file(I called it vwManageUser.php) I am getting the following errors:

 

 

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: css_files

Filename: admin/vwManageUser.php

Line Number: 9

A PHP Error was encountered

Severity: Warning

Message: Invalid argument supplied for foreach()

I can send you the code to have a viewpoint of the project.

 

I have added the examples.php in application\controllers\admin\examples.php

?>
 

 

 

in the config\autoload.php I have changed libraries to:

 

$autoload['libraries'] = array('database', 'session', 'grocery_CRUD','image_moo');

 

I have created separately another project for testing grocery crud only and it was working perfect. I don't really understand how to solve the issues. 

Moreover, In the new project by pressing any of the following links Customers | Orders | Products | Offices | Employees | Films |

i am getting the following error

 

An Error Was Encountered

The configuration file grocery_crud.php does not exist.

 

 

I will really appreciate if you could help me. Thank you for your time.

Have a look at your view file (html).

 

This code in the header:

 

<?php 
foreach($css_files as $file): ?>
<link type="text/css" rel="stylesheet" href="<?php echo $file; ?>" />
<?php endforeach; ?>
<?php foreach($js_files as $file): ?>
<script src="<?php echo $file; ?>"></script>
<?php endforeach; ?>
 
For some reason, view is not receiving the correct values for $js_files and $css_files vars.
 
You can try to remove these lines and see if it works (it may look ugly because of no css styles, and may have lacking funcionalities because of missing js files).
 
If this fixes your problem, next step would be finding why $js_files and $css_files dont have a correct value, and solving it (probably error is located in the controller)

I solved that. I had to define the grocery crud config file into the controller and in the controller file examples.php to change

 

FROM:

 

public function _example_output($output = null)

{
$this->load->view('/views/admin/vwManageUser.php',$output);
}

 

 

TO:

public function _example_output($output = null)
{
$this->load->view('admin/vwManageUser.php',$output);
}
