How to display multiple ck editor in array in php passing same id?

Question

I am doing a project in codeigniter and I came across a problem of displaying multiple ckeditor for objective answer to a question in my view.

   <div class="col-md-6">   
   <textarea id="objective_answer" name="objective_answer"><?php echo set_value('objective_answer', $answer); ?></textarea>   
    <?php echo form_ckeditor(array('id'=>'objective_answer'));  ?>

     </div>

    <?php  }  ?>

The above code displays one ck editor fine.But I have to show lets say 4 ckeditor for writing 4 objective answers to a question. Can anyone help me how to do this?

Answer 1

create a counter and set unique ids for the text areas:

<?php for($i=0;$i<4;$i++){?>

<div class="col-md-6">   
    <textarea id="objective_answer<?php echo $i;?>" name="objective_answer">
        <?php echo set_value('objective_answer', $answer); ?>
    </textarea>   
    <?php echo form_ckeditor(array('id'=>'objective_answer'.$i));  ?>
</div>
<?php }
