Codeigniter: The default value of a text input field if data is not returned from the controller

I have a text input which is populated by values from the database passed from the controller. This is how I have done it: 

<input type="text" class="form-control" id="groupname" name="groupname" disabled value="<?php foreach ($result as $r) {
    echo $r->group_name;
};?>"/> <br>`

This code should be executed once a search button is clicked and its working well. My problem is, every time I load the view,this input field is loaded meaning this code executed and since I have not searched anything, it is giving me an error. How can I set the default value of the input box to be null/empty by default or if no value is returned from the controller.

Am a newbie. Your help is much appreciated.

You can check whether search performed or not by checking your array 

<input type="text" class="form-control" id="groupname" name="groupname" disabled value="<?php if(isset($result) && !empty($result)){ foreach ($result as $r) {
    echo $r->group_name;
} };?>"/> <br>`

Explanation

I use if(isset($result) && !empty($result)){ condition in this i have checked that if your search happens that means there $result will be set and there must be something in $result. But if you simply refresh page then there is no value in $result so it will not process foreach loop.

You should set empty array with $result = array(); before your call to the function, or you can do it in the foreach(), like this foreach((array)$result as $r)... see more here: foreach()

you could try this:

    <input type="text" class="form-control" id="groupname" name="groupname" disabled value="
<?php 
   if(count($result)>0){ 
       foreach ($result as $r) {
          echo $r->group_name;
       }
   }?>"/> <br>
