Calling Img From Base URL in CodeIgniter - php

Question

So normally I would <?php echo base_url();?>but im not sure how to do it in this code.
<?php
$path = 'home';
$img = '<img src="../img/servare.png" alt="">';
echo anchor($path, $img);
I have tried...
<?php
$path = 'home';
$img = '<img src="' <?php echo base_url();?>'../img/servare.png" alt="">';
echo anchor($path, $img);
But the img is not showing, any ideas ?

Answer 1

Your solution is one of the three following options:
If you're trying to create a text with a link to the image:
$this->load->helper('url'); // Load URL Helper for base_url()
$this->load->helper('html'); // Load HTML Helper for img()
$path= base_url('img/servare.png'); // generates text: siteroot/img/servare.png
$text = 'Visit Image';
echo anchor($path, $text);
OUTPUT HTML:
Visit Image
If you're trying to display the image in the current page,
$path= base_url('img/servare.png'); // generates text: siteroot/img/servare.png
echo img($path);
OUTPUT HTML:
<img src="http://localhost/nedwara.com/img/servare.png" alt="">
If you're trying to display the image in the current page and open the full image when clicked as a link,
$this->load->helper('url'); // Load URL Helper for base_url()
$this->load->helper('html'); // Load HTML Helper for img()
$path= base_url('img/servare.png'); // generates text: siteroot/img/servare.png
echo anchor($path, img($path));
OUTPUT HTML:
<a href="http://localhost/nedwara.com/img/servare.png">
<img src="http://localhost/nedwara.com/img/servare.png" alt="">
</a>

Answer 2

I think your code should be:
<?php
$this->load->helper('url');
$path = 'home';
$img = '<img src="<?php echo base_url('img/servare.png');?>" alt="">';
echo anchor($path, $img);
Because as seen in http://www.codeigniter.com/user_guide/helpers/url_helper.html
base_url:
Returns your site base URL, as specified in your config file.
Eg. If your site is http://example.com then:
base_url() returns "http://example.com"
and base_url('img/servare.png') will return "http://example.com/img/servare.png"
