Question

I am fetching all details of product from database, and successfully get in view, but in between there is product details is too long so i want to split that text. I have also create a function of limit_text in main controller that is:

function limit_text($text, $length) // Limit Text
{
    if(strlen($text) > $length) {
        $stringCut = substr($text, 0, $length);
        $text = substr($stringCut, 0, strrpos($stringCut, ' '));
    }
    return $text;
}

but problem is that i unable to call this function from view....please help me..

Instead of creating function in your controller, i suggest you create it in helper so that you can access it easily from view file. Create helper, say mysome_helper.php:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

function limit_text($text, $length) // Limit Text
{
    if(strlen($text) > $length) {
        $stringCut = substr($text, 0, $length);
        $text = substr($stringCut, 0, strrpos($stringCut, ' '));
    }
    return $text;
}

and load it in your controller:

$this->load->helper('mysome');

and then you can access in view, like:

<?php echo limit_text("some long tezxt", 120); ?>
