I am afraid that this code is not going to work until someone with a minimum 
clue will be rewriting it.  For example,

| echo "<li><button id=$bgname onclick = return(blogId($this))>".
| $row['blogs_name']."</button></li>";

is not going to work already because “$this” will be expanded to "" while 
generating the notice “Undefined variable: this”.  It must be “this” 
instead, and the “onclick“ attribute value must be quoted; but to know that 
you have to have at least a basic understanding of HTML, and you have to 
know the difference between server-side and client-side code, and between 
PHP (used here server-side) and ECMAScript/JavaScript (used here client-
side).
