A primer is a short single-stranded nucleic acid utilized by all living organisms in the initiation of DNA synthesis. The enzymes responsible for DNA replication, DNA polymerases, are only capable of adding nucleotides to the 3’-end of an existing nucleic acid, requiring a primer be bound to the template before DNA polymerase can begin a complementary strand. Living organisms use solely RNA primers, while laboratory techniques in biochemistry and molecular biology that require in vitro DNA synthesis (such as DNA sequencing and polymerase chain reaction) usually use DNA primers, since they are more temperature stable.
Dear Mohammed
in case it could be useful, i uploaded some video with guidelines for primer design for cloning of pcr fragments into plasmids at PAGE1 of my blog ProteoCool (https://proteocool.blogspot.com)

Hey,
Use this link. It is easy to read and so far give the best result for primer designing!

I think designing manually gives you a greater understanding of the molecular biology than following the book pattern.
