PHP-在Codeigniter中使用$ this-> db-> get（） - > result（）

I'm trying to create a web page that when user click on the below link,it will bring user to the next page

<a href="../try/sewcutrptsummary?pro={$row ->idmsul}" target="blank"">Link

My question is,how can i retrieve the same data from 1st page & display it in a textbox in 2nd page as shown in below pictuce?

Retrieve data

This is the view for the 2nd page

<div class="control-group">
<label for="proid" class="control-label">MSUL ID</label>
<div class="controls"> 
 <input type="text" id="txtinput" name="txtinput"value="">
<select id="prodtype" name="prodtype"onchange="checknumber();">
<option selected >--Select Product Type--</option>
 <option value="Main"  >Main</option>
 <option value="Sub">Sub</option>
</select>
</div>
<div class="controls" id="after" style="display : none">         
<select id="cutprod" name="cutprod" class="input-xxlarge">
</select>

<input id="generatebtn" type="button" class="btn-primary btn-small" onclick="generateRpt();" value="Generate" ></div>
</div>

and this is the controller

function index() {
        $this -> smarty -> assign("page", "View Cutting Report Summary");
        $this -> smarty -> assign("dataname", "Cutting Report Summary");
        $this -> smarty -> assign("pagename", "sewcutrptsummary");
        $this -> smarty -> assign("msg", "");
        $this -> smarty -> assign("script", "Yes");

        $idmsul = $this -> input -> get_post("pro");
        $query = "Select idmsul from sindi_schedule where idmsul='{$idmsul}' group by idmsul";
        $result = $this -> global_model -> query($query) -> result();
        $data['idmsul'] = $result;

        $this -> smarty -> view('sewcutrptsummary.tpl',$data);
        }

Can anybody assist me on this problem?

Your help is greatly appreciate.

Simple pass the data pro to view like this

In controller :

.....
$data['idmsul'] = $result;
$data['id'] =$this->input->get_post("pro"); //here pass the id to view 
$this->smarty->view('sewcutrptsummary.tpl',$data);
....

In view :

<input type="text" id="txtinput" name="txtinput" value="{$id}">

You are passing the data as a query string, therefore the following should work

if(isset($_GET["pro")) {  // Safeguard in case value is not there
    $pro = $_GET["pro"];
}

Then assign the value of your textbox to $pro
