Helpers are functions that help in your code. There are some helpers in codeigniter 4 like html helper, URL helper, from helper, text helper, cookie helper and many more. The work of all helpers is different. Such as linking css files in html helper work view file, creating URL helper work link, form helper's work building form.
We can also make helper custom. Who does his according work.
The custom helper we save is named filename_helper.php. Create this file in a folder containing helpers.
// helper expample user_helper.php profile_helper.php admin_helper.php helpers/user_helper.php helpers/profile_helper.php helpers/admin_helper.php
The helper can also be loaded anywhere in the controller. For example:
// load single helper in controller helper('text'); helper('from'); helper('url'); // text helper example echo word_limiter('my name is deepak tailor',4); // output : my name is deepak... // from helper example echo form_open('home/submit_form'); echo form_close(); // url helper example echo base_url(); // output : my name is deepak... // load multiple helpers in controllers with array helper(['text','from','url']);
