Override Existing Helper In Codeigniter

In this article, we will perform following actions

Let us work on the examples.

File Naming Convention

To override the existing helper, you must follow these steps

Create a file in the "Helpers" folder.
File naming convention should be "MY_helperclass_helper.php". For example if you want to override date helper then the file name should be "MY_date_helper.php".

In this example, we will call the existing method "nice_date"

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

$bad_date = '199605';

$better_date = nice_date($bad_date, 'Y-m-d');

echo $better_date;

Here is the output

Now, add a new function inside "MY_date_helper.php"

<?php
function showmessage()
{
    echo "Calling showmessage";
}

And finally call the new method.

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

showmessage();

Here is the output

To override the existing function, write the function with the same name

function nice_date($date, $format)
{
echo "nothing";
}

Now call the same method

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

$bad_date = '199605';

nice_date($bad_date, 'Y-m-d');

Here is the output
