You are missing a quote just before $post_image:

,$post_image'

Should be:

,'$post_image'

So the complete SQL statement becomes then:

$insert_query = "INSERT INTO posts 
    (post_title, post_date, post_author, post_image, post_keywords, post_content)
    VALUES ('$post_title', '$post_date', '$post_author', '$post_image', 
            '$post_keywords', '$post_content')";

Please note that you are doing assignments in this if:

if ($post_title=='' or $post_keywords='' or $post_content='' or $post_author=''){

You should be using double == instead of =.

Finally, your code is vulnerable to SQL injection. So please use prepared statements with parameters.
