you are asking how to modify the link, so yes, you would edit the a href tag.
I'm not entirely sure what your expected outcome is, so can't really give you much more guidance.
this code:
blog-article.php?zzBlogItems=<?php echo $row_BlogRS['ContentPageSetOrder']; ?>
generates the link URL. if the BlogRS recordset returns a Title column and you are trying to add a title url variable, the code for the URL would be:
blog-article.php?zzBlogItems=<?php echo $row_BlogRS['ContentPageSetOrder']; ?>&title=<?php echo strtolower(str_replace(" ","-",$row_BlogRS['title'])); ?>
