The problem im having is with the edit section in my code, i got the add article section working correctly, specifically the problems im having are with the image update,
when i create a new article and select a featured image it adds it and store the filename in the database,
the problem is when a new article was created and a featured image was not selected,
whenever i add an image in "edit" i always get "
You did not select a file to upload." error, all i want is to get the filename of the image but it always fails when its on
"edit" even though the same code is repeated on
"add".
I dont know what else to do to be able to get that filename, i looked around and still the get the same error, here is the complete add and edit method in the Articles Controller :

Edit View:
Code:
<form method="post" action="<?php echo base_url(); ?>admin/articles/edit/<?php echo $article->id; ?>">
<!-- other input fields here ... -->
<div class="form-group">
<label>Featured Image</label>
<?php if( $article->post_image == null || $article->post_image == '' ) :?>
<p><strong>No Image</strong></p>
<label>Insert Featured Image</label>
<input type="file" name="post_image" />
<?php else : ?>
<img src="<?php echo base_url() . 'uploads/' . $article->post_image ; ?>">
<?php endif; ?>
