Question

i am using codeigniter library, and am stuck in a matter. first here’s my array

Array (
    [0] => Array (
        [product_name] => some data
        [product_slug] => some data
        [price] => some Data...
        [sell_price] => 2000.00

    )

    [1] => Array (
        [product_name] => some data
        [product_slug] => some data
        [price] => some Data...
        [sell_price] => 2000.00
    )
)

now here’s my code in controller:

$this->load->model('product_model');
$data['product']=$this->product_model->get_product();
$this->load->view('show_product',$data);

and heres my model codes

function get_product()
{
  return $this->db->query("SELECT * FROM dt_product")->result_array();
}

and ultimately my view code

<div class="featured_right_gallery_bellow">
                    <ul class="product_list">
                                        <?php foreach($product as $product)
                                        {?>
                    <li>
                    <div class="pro_name"><?php echo $product['product_name'];?></div>
                    </li>
                    <?php
                    }?>
                    </ul>
</div>

now my question is that, i want to jst show the first 20 letters of the product_name….but here the full name is being shown…

i know i can write a mysql code like SELECT LEFT(product_name,20),sell_price,price FROM dt_product… but i dont want to do that, because the table contains nearly 20 attributes, and i have to change the query multiple times…. all i want is to someone point me out to the solution of how to display the first 20 letter of the product_name using the offset concept,

i tried echoing $product[‘product_name’][20], but withing foreach loop, its throwing an error of undefined index..

Answer 1

Try this:

<div class="pro_name"><?php echo substr($product['product_name'], 0, 20);?></div>

Read up on function substr() here: http://php.net/manual/en/function.substr.php

Edit:

If you want to do the edit directly in your array (which I don’t think is necessary):

Assuming $array is the array:

Array (
    [0] => Array (
        [product_name] => some data
        [product_slug] => some data
        [price] => some Data...
        [sell_price] => 2000.00

    )

    [1] => Array (
        [product_name] => some data
        [product_slug] => some data
        [price] => some Data...
        [sell_price] => 2000.00
    )
)

Then do this:

// Iterating through each of the elements of the array.
// $productArray gets loaded as each inner array value.
foreach ($array as $key => $productArray) {
    // The value of $array[$key] is the current inner array.
    // The substr() just gets the value of the product_name key and returns the first 20 characters.
    // To load the modified value, set $array[$key]['product_name'] to the modified value.
    $array[$key]['product_name'] = substr($productArray['product_name'], 0, 20);
}
