I'll continue my post about jcrop library

Code:

public function add_form($forms) {

        if (is_array($forms)){

            $input = $this->form;

            foreach($forms as $key=>$val) {

                switch ($key) {

                    case 'form_input':

                    $input .= '<p>&lt;input type="text" ';    

                    foreach ($val as $k=&gt;$v){

                        $input .= $k.'="'.$v.'" ';

                    }

                    $input .= ' /></p>';

                    break;

                    

                    case 'form_textarea':

                    $input .= '<p>&lt;textarea ';    

                    foreach ($val as $k=&gt;$v){

                        if($k<>'value'){

                            $input .= $k.'="'.$v.'" ';

                        }

                    }

                    $input .= ' >'.$val['value'].'&lt;/textarea&gt;&lt;/p>';

                    break;

                    

                    case 'form_dropdown':

                    $input .= '<p><select ';

                    $input .= 'name="'.$val[0].'" >';

                    $input .= '<option selected>'.$val[2].'</option>';

                    foreach( $val[1] as $k=>$v ){

                        $input .= '<option value="'.$k.'">'.$v.'</option>';

                    }

                    $input .= '</select></p>';

With this library we could add som input text as we need. Before we store our data into a database. This library use the CI function except the process resizing and producing image as result. because when i use the CI functionm, I get the bed proportion of image.

This Library has many weaknes ,
eg. on the producing form , we cannot produce same field type on one form type
so i need contribution from from you all.
on next section i will show you how to implementing this library on controller
