base_url在codeigniter的php标签内未显示所需结果

Question

i am trying to output the image inside php tag through base_url function. it tried using different combination of quotes but nothing seems to be working here. can any point out exactly where i am doing wrong?

$image_url =$this->input->get("image",true);
echo "<img src='base_url('uploads/add_pic/')'.$image_url /> "."<br>";

while in output i am getting

localhost/myproject/online_marketplace_controller/base_url(

kindly help me in this regard

Answer 1

used this type

<img src="<?php echo base_url('uploads/add_pic/'.$image_url);?>">

OR

echo "<img src='".base_url()."uploads/add_pic/".$image_url."'><br>  ";

Answer 2

Make sure you set your base url like

$config['base_url'] = 'http://localhost/myproject/';

Then on your view

<img src="<?php echo base_url('uploads/add_pic/' . $this->input->get("image"));?>">

Also you can use the html helper https://www.codeigniter.com/user_guide/helpers/html_helper.html

Make sure you load the helper in the controller or autoload it.

<?php

$image_properties = array(
   'src'   => 'uploads/add_pic/' . $this->input->get("image"), 
);

echo img($image_properties);

?>

Answer 3

你可以这样使用

<img src="<?php echo base_url();?>uploads/add_pic/<?php echo $image_url; ?>">
