MY Form validation - Simple Callbacks into Models

[eluser]umbongo[/eluser]
Yes, thanks.. this was missing. I assumed it was loaded by My_form_validation as it seemed to work elsewhere without loading the model.. but upon closer inspection it was loaded in that case for something else. And thanks for making this.
Maybe this could be implemented?

If you really need that you could try loading the required model by editing the following lines:

Code:

// >>> START of modification

        $model = FALSE;

        if (strpos($rule, '_model') AND $param)
        {
           $model = $param;
           $rule = substr($rule, 0, -6);
        }

        // Is the callback into a model?
        if ($model)
        {
            if ( ! method_exists($this->CI->$model, $rule))
            {
                continue;
            }

            // Run the function and grab the result
            $result = $this->CI->$model->$rule($postdata);
        }
        else
        {
            if ( ! method_exists($this->CI, $rule))
            {
                continue;
            }

            // Run the function and grab the result
            $result = $this->CI->$rule($postdata, $param);
        }

// <<< END of modification

We'll check whether the model is already loaded. If not we'll try to load it.

WARNING: This code is not tested and is based on an older than v1.7.3 CodeIgniter release. This code doesn't search for models within subfolders, doesn't take into account model name aliases and assumes your model class will be named following the CodeIgniter coding conventions (first letter capitalized with the rest of the name lowercase or underscore).

Code:

// >>> START of modification

        $model = FALSE;

        if (strpos($rule, '_model') AND $param)
        {
           $model = $param;
           $rule = substr($rule, 0, -6);
        }

        // Is the callback into a model?
        if ($model)
        {
            if ( ! isset($this->CI->$model))
            {
                // If you need to auto-connect to the default database add TRUE on the last parameter
                // $this->CI->load->model(ucfirst($model), '', TRUE);
                $this->CI->load->model(ucfirst($model);
            }

            if ( ! method_exists($this->CI->$model, $rule))
            {
                continue;
            }

            // Run the function and grab the result
            $result = $this->CI->$model->$rule($postdata);
        }
        else
        {
            if ( ! method_exists($this->CI, $rule))
            {
                continue;
            }

            // Run the function and grab the result
            $result = $this->CI->$rule($postdata, $param);
        }

// <<< END of modification
