Problem with custom navigation bar

Question

I'm trying to create a custom left navigation bar with adaptive tag. when user click on the link it will direct to a pagelet which is created with page template. How can I do it? I don't understand what is pt:objectid? Where can I look for answer? I just need a simple example. Thank you.

Answer 1

You can get the object id from the "Edit this Community" feature under "My Communities" then look in "properties and names". If you look in the address bar you could also see the objid in there (objId=1234). I was having problems with this too.
What I did was use the ptdata tag like this:
<div id="topNav">
<pt:ptdata.currentcommunityiddata pt:id="currcomm" />
<pt:ptdata.subcommunitiesdata pt:commid="1234" pt:id="subcommunityPages" />
<ul>
<pt:standard.choose>
<pt:standard.when pt:test="isMatch" pt:str1="$currcomm.objid" pt:str2="3217">
<li class="down">
</pt:standard.when>
<pt:standard.otherwise>
<li>
</pt:standard.otherwise>
</pt:standard.choose>
<pt:standard.openerlink pt:objectid="3217" pt:classid="512" pt:mode="2">Home</pt:standard.openerlink>
</li>
<pt:logic.foreach pt:data="subcommunityPages" pt:var="varCommunityPage">
<pt:standard.choose>
<pt:standard.when pt:test="isMatch" pt:str1="$currcomm.objid" pt:str2="$varCommunityPage.objid">
<li class="down">
</pt:standard.when>
<pt:standard.otherwise>
<li>
</pt:standard.otherwise>
</pt:standard.choose>
<pt:core.html pt:tag="a" href="$varCommunityPage.url" title="$varCommunityPage.title">
<pt:logic.value pt:value="$varCommunityPage.title"/>
</pt:core.html>
</li>
</pt:logic.foreach>
</ul>
</div></p>
<p>This is for a community that has subcommunities. you could also do the same thing with pages instead.
Short explaination:
This line sets up a data object for the current community data and assigns it the variable name "currcomm":
<pt:ptdata.currentcommunityiddata pt:id="currcomm" /></p>
<p>This line gets the subcommunities for a particular community (in this case commid="1234" ). You specify which community with the pt:commid.
<pt:ptdata.subcommunitiesdata pt:commid="1234" pt:id="subcommunityPages" /></p>
<p>I used a <ul> for it but you could really do it any way you want.</p>
<p>I added a static "home" tab that will always link to my top level page of the community. this is optional and there may be a better way of doing it:
<pt:standard.choose>
<pt:standard.when pt:test="isMatch" pt:str1="$currcomm.objid" pt:str2="3217">
<li class="down">
</pt:standard.when>
<pt:standard.otherwise>
<li>
</pt:standard.otherwise>
</pt:standard.choose>
<pt:standard.openerlink pt:objectid="3217" pt:classid="512" pt:mode="2">Home</pt:standard.openerlink>
</li></p>
<p>for a link to your page you can use this tag. You can get both the objectid and classid from the "properties and names" page as mentioned above. pt:mode is how/what should be displayed (The action of the link (Opener mode). 1 = Open, 2 = View, 3 =ViewMeta.)
<pt:standard.openerlink pt:objectid="3217" pt:classid="512" pt:mode="2">
I also have a choose in there to test if the current community you're in is the same as the community of the link. That lets me add a class="down" for a down state. </p>
<p>This loops through all the subcommunities and builds a link in this format <li>TITLE OF COMMUNITY</li>. </p>
<p><pt:logic.foreach pt:data="subcommunityPages" pt:var="varCommunityPage">
<pt:standard.choose>
<pt:standard.when pt:test="isMatch" pt:str1="$currcomm.objid" pt:str2="$varCommunityPage.objid">
<li class="down">
</pt:standard.when>
<pt:standard.otherwise>
<li>
</pt:standard.otherwise>
</pt:standard.choose>
<pt:core.html pt:tag="a" href="$varCommunityPage.url" title="$varCommunityPage.title">
<pt:logic.value pt:value="$varCommunityPage.title"/>
</pt:core.html>
</li>
</pt:logic.foreach>
</p>
<p>Hopefully that is what you're trying to do.
Like I said, you can use the same process for pages instead of subcommunities by using the communitypagesdata tag instead of subcommunitiesdata. You could also combine the two and list all the subcommunities with a foreach loop and inside each loop get the pages from the communitypagesdata with the commid set to the subcommunity objid for that subcommunity.</p><p>
THis document is very helpful with PT tags... [url http://e-docs.bea.com/alui/devdoc/docs60/References/API_Libraries/TagDocs/index.html]http://e-docs.bea.com/alui/devdoc/docs60/References/API_Libraries/TagDocs/index.html</p>
