<div id="your_post">
<div id="post_image">
<img   id ="post_img" src="<?php  echo $this->config->item('base_url'); ?><?php echo '/application/css/'. $img ?>"/>
</div>
<textarea name="post" rows="5" cols="30" placeholder="Share an update..." id="post_text" rows="2" value=""></textarea>

//other view items
            <?php
    echo form_close();
    ?>

Change:

<?php echo form_open_multipart('search/post_func');?>

Change:

$this->upload->do_upload()

To this:

$this->upload->do_upload('my_file_input_name')

and it will work!! :)
