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).
