validation errors output - El Forum - 07-30-2007

Here's a simple tip, which might save somebody a couple of minutes.

The default output of each validation error is wrapped in paragraph tags. I wanted to use list item tags.

Fortunately the Validation class defines two properties, _error_prefix and _error_suffix, which makes it easy to change them. Create an extended class (if you haven't previously done so) and define the new values in the Constructor.

Code:
class My_Validation extends CI_Validation 

{

    /**

     * Constructor

     *

     */    

    function My_Validation()

    {    

        parent::CI_Validation();

        $this->_error_prefix = '<li>';

        $this->_error_suffix = '</li>';

    }

}

Doesn't the following code work?

Code:
$this->validation->set_error_delimiters('<li>', '</li>');

Yeah, sure, if you want to do it the easy way. :-)

Thanks... same difference actually, but I completely missed that function. Rick didn't miss a trick.

I display the errors at the top of my form views like this:

Code:
&lt;?php if(isset($page_type) && $page_type=='form'){

    $this->load->view('shared/display_error_messages',$data);

    // don't show the required fields notice on deletion confirmation forms

    if(!strpos($page_title,'delete')) {

        echo '<p class="note"><strong>Bold</strong> fields are required.</p>' . "\r\r";

    }

} ?&gt;

The shared/display_error_messages view:

Code:
&lt;?php

if(isset($this->validation->error_string)){

    if(count($this->validation->_error_array) > 0) {

        $display = '<div id="errors">' . "\r\r";

        $display .= "<p>Sorry, we had some trouble with your form.</p>\r\r";

        $display .= "<ul>\r";

        $display .= $this->validation->error_string;

        $display .= "</ul>\r";

        $display .= "</div>\r\r";

        echo $display;

    }

}

Thanks for sharing your snippet. I'm going to do something global like that.
