Excluding Content

I am not sure I understand what you are trying to do.
Are we talking about Pages? If so, if you “exclude” the content of a Page… what the heck is shown on that Page?
Try to describe exactly what you want to achieve, somebody might come up with the solution.

I have a different nav bar on 4 pages on my site. On the rest of the pages, I have the same nav bar. I want to find a code that will allow me to use the code:
<?php if ( is_page() ) : ?>
<?php endif; ?>
but at the same time, exclude 4 pages.

Currently I am doing it all by hand whereas the code reads:
<?php if ( is_page(#) ) : ?>
<?php endif; ?>
And I do this for each of the pages.

I don’t want to recreate the code for each of the pages. If you want to see, https://cs.loyolahs.org/news/

Any help is greatly appreciated!

Then your topic title is totally misleading!
You do NOT want to exclude content – you want to exclude certain Pages from being listed on some particular Pages. That’s a totally different story.

See: https://codex.www.ads-software.com/Conditional_Tags#A_PAGE_Page
You are on the right track but you have to study the working examples in the Codex article above.
You can approach it in two ways:
if is_page(1,2,3,4)
do stuff… <== your code here
endif

or

is !is_page(1,2,3,4) <== which means if is NOT the listed Pages. The [!] means NOT.

Here is the code I am using:

<?php if ( !is_page(8,9,10,11) ) : ?>
<table border=”0″ cellpadding=”0″ cellspacing=”2″ width=145>
<tr>
<td width=”100%”>CS Home</td>
</tr>
<tr>
<td width=”100%”>CS Leadership Team</td>
</tr>
<tr>
<td width=”100%”>Urban Plunge</td>
</tr>
<tr>
<td width=”100%”>Food & Clothing Drive</td>
</tr>
<tr>
<td width=”100%”>Web Resources</td>
</tr>
<tr>
<td width=”100%”>Press Room</td>
</tr>

</table>
<?php endif; ?>

But for some reason, the conditional tag only works of the first page listed. Any ideas?

Sorry, I am a code-illiterate…
But I think it should be something like
<?php if ( is_page(1) || is_page(1) || is_page(3)... etc. ) { ?>

This is what I tried:

<?php if ( !is_page(8) || !is_page(9) || !is_page(10) || !is_page(11) ) : ?>
Content
<?php endif; ?>

<?php if ( !is_page(8) is_page(9) is_page(10) is_page(11) ) : ?>
Content
<?php endif; ?>

<?php if ( !is_page(8) !is_page(9) !is_page(10) !is_page(11) ) : ?>
Content
<?php endif; ?>

None worked. Any ideas?

Thought I would bring this up again. Does anyone have any ideas? Thanks for the help in advance!
