Do any one has any idea from where the below $ isUserLoggedInor $hideRegisterLink variable is fetching its data? The code is from navar.tpl in OJS http://pkp.sfu.ca/?q=ojs.
Note:OJS uses smarty templating
{if $isUserLoggedIn}
<li id="userHome"><a href="{url page="user"}">
{translate key="navigation.userHome"}</a></li>
{else}
<li id="login"><a href="{url page="login"}">
{translate key="navigation.login"}</a></li>
{if !$hideRegisterLink}
<li id="register">
<a href="{url page="user" op="register"}">
{translate key="navigation.register"}</a></li>
{/if}
{/if}{* $isUserLoggedIn *}
If anyone is interested other than me,Its coming from pre-defined variable from OJS it self.you can visit this page for more info http://pkp.sfu.ca/ojs/docs/technicalreference/2.1/userInterfaceVariables.html
