How to Create New Page Template without Sidebar

Does your theme have a single column layout by chance? When you are editing a page, you can select the layout via drop down menu on the right.

copy page.php, rename copy as page-forum.php or page-ID.php, where ID is id of the forum page, and remove the line with <?php get_sidebar(); ?>.

My theme does NOT have a single-column layout in the pulldown list.

And Andrei, I did what you suggested–at least I think I did, although I called it fullwidth.php, created using Dreamweaver with a simple copy and paste but adding these five lines to the top:

<?php
/*
Template Name: Full Width Template
*/
?>

I took out the

<?php get_sidebar(); ?>

and saved out my changes and uploaded to my theme, producing the error.

Here’s the page as it is now, but producing the errors:

[code moderated - please follow the forum guidelines for posting code]

try this..

[code moderated - please follow the forum guidelines for posting code]

i just remove the

if (have_posts()) : while (have_posts()) :

It works just fine. What kind of errors?

Here’s what it’s doing: when I go to the Page, go to Edit, use the pulldown and choose ‘Full Width Template’, Update my changes and go to ‘View Page,’ it returns a page that just displays all of
the php coding for the page, rather than producing the actual page…

yep, fine for me either..

displays all of the php coding for the page

what do you mean by that?

I mean that when I click on the tab for the page, I don’t get the page displayed. I get all of the php coding displayed, as if I was in the theme editor.
When I switch the page over the the ‘Default’ template, with the sidebars I don’t want, the page displays properly.

Maybe Dreamweaver messed up and interpreted php code as html markup and changed it so. I hope you pasted the code in code view and not visual/wysiwyg mode.

Did you try opening and editing php file with notepad or another editor ( like vim or notepad++. The last one would probably be better for you)?

Andrei,
Thanks! Partial resolution of my problem. I tried working directly in my page-forum.php file and simply doing an ‘Update File’ and now it’s properly showing the page!
HOWEVER: It’s still only using the 620 px of the 920px that Mimbo defines. This is the width of the ‘Content’ in the stylesheet.

Here’s a link to the entire Mimbo stylesheet:

Is there a way I can define something different for my page-forum template?

Thanks to all who have contributed to this, I really appreciate your help.

Just add #post-4038 { width:910px; } to your stylesheet.

or this..

.page-template-page-forum-php #content{width: 910px !important;}

You don’t need !important there.
