WordPress Template Tags

Template tag-urile reprezinta un set de functii ce au rolul de a prelua continutul din baza de date si a-l afisa in cadrul unui template (si nu numai). Continutul poate fi orice, de la titlul blogului pana la un sidebar complet. Aceste functii (template tags) :

  • au rolul de a afisa continut in cadrul unei teme de WordPress intr-un mod dinamic
  • pot fi folosite in cadrul mai multor fisiere din tema
  • cu ajutorul lor poti imparti continutul unui template in sectiuni mai mici si mai usor de inteles
the_content(); // Get post content
the_excerpt(); // Get the post excerpt
the_title(); // Get the title of the post
the_permalink(); // Display post link
the_category(','); // Display category of a post
the_author(); // Show post author
the_ID(); // Display post ID
edit_post_link(); // Show Edit link for a post
