How to make a dynamic link?

I have created blog pages. I have added category field in blog. Drop down menu so only few categories. Well lets say i m in blog page where all blog post are displayed from all categories.
So now if i want to view post from only a particular post how do i add dynamic link it? also a dynamic page.

Not like i create a new page & insert a WHERE rule in recordset.

What you are asking about is a master details page set.

in your master list, the list of all blogs from all categories, you would have a link that passes the blog id to the detail page.

on the detail page, the recordset would use the ID URL variable in the where clause. the database starter kit tutorial here:

has an example of how to create a master detail page set.

Well attached image is a dynamic blog page where a single blog post is seen.
& if you look closer below the image you can is that particular post comes under category on MARINE.
So i want to make that particular word clickable. Every post will have different category. I have like 5-6 categories.
All field you can see is from DB. so when someone's clicks the category name (dynamic) it should show all post in that particular category.

Yes the database starter kit tutorial will give you the information needed to create this.

the basic concept is to create a link that passes the category ID as a URL variable

for example
categorypage.php?catID=3

then on the category page, you have a recordset that uses the catID URL variable to filter the blog posts for that category.

this is very basic recordset filtering

That was simple & easy.

Thank You :)
