Only Showing Content & Comments To Registered Users In WordPress

Recently one of my clients asked if it was possible to only show content to registered users on a WordPress site.

The solution is very simple using WordPress’ filter system.

add_filter("the_content", "block_content" );
add_filter("comment_text", "block_comment");

function block_content($content){
if(!is_user_logged_in()){
return __( ‘You must be logged in to view content’ );
}else{
return $content;
}
}
function block_comment($content){
if(!is_user_logged_in()){
return __( ‘You must be logged in to view comments’ );
}else{
return $content;
}
}

Putting that snippet in your theme’s functions.php file will swap comment, page and post content with the messages above.

WordPress Template is missing

Recently while working on a custom WordPress theme I kept running into the issue where my theme would become unusable and in my Appearance section of the back end I would get the error “Template is missing” for my theme.

Often you get this error when you are trying to inherit from a theme but the theme cannot be found,  in my case my theme wasn’t inheriting from another so I couldn’t work out why I was getting this error.

Eventually after a lot of careful cross checking I figured it out

I had to remove any comments that contained the string “TEMPLATE:”, this may also be caused by the lower case “template:” but I didn’t test this.

I had comments like this in as part of my stylesheet:

/* TEMPLATE: Sidebar content */

This was causing WordPress to look for a theme that didn’t exist.

I assumed that WordPress would only look in the top comment block for the theme information but i was wrong…

Turning CakePHP’s Pagination output to a list

I’ve spent the last few hours investigating how to style the out produced by cakes $paginator helper.

I managed to get a digg style output for my pagination by styling the output produced by default, but because of the number of divs and spans that had to be floated i thought that it would be much easier to style if it were a list.

The default output generated by the Bake scaffolding looks something like this

CakePHP Default Pagination

and the html like

<div class="paging">
<div class="disabled"><< previous</div>
<span class="current">1</span> |
<span><a href="/cakephp/cms/admin/blog/posts/index/page:2">2</a></span> |
<span><a href="/cakephp/cms/admin/blog/posts/index/page:3">3</a></span>
<a href="/cakephp/cms/admin/blog/posts/index/page:2">next >></a>
</div>

This can be quite easily changed to a list output by using the $options parameter of the $paginator->numbers() function.

In your views where you are using pagination find the call to the $paginator->numbers() function. On my 1.2.6 version of CakePHP it looks like this

numbers();?>

Change this to the following

prev(‘<<’.__(‘previous’, true), array(), null, array(‘class’=>‘disabled’));?>
numbers();?>
next(__(‘next’, true).‘ >>’, array(), null, array(‘class’ => ‘disabled’));?>

This will then produce output similar to this (it depends what page your on)

<div class="paging">
<a href="/cakephp/cms/blog/posts/index/page:1"><< previous</a>
<ul class="pagination">
        <li><a href="/cakephp/cms/blog/posts/index/page:1">1</a></li>
        <li class="current">2</li>
        <li><a href="/cakephp/cms/blog/posts/index/page:3">3</a></li>
</ul>
<a href="/cakephp/cms/blog/posts/index/page:3">next >></a>
</div>

To style this digg-stylee you can use the following CSS, just add it to your apps main CSS file.

div.paging a{
border:solid 1px #9aafe5;
margin-right:2px;
display:block;
float:left;
padding:3px 4px;
}
ul.pagination li{
border:0; margin:0; padding:0;
font-size:11px;
list-style:none;
margin-right:2px;
}
ul.pagination a{
border:solid 1px #9aafe5;
margin-right:2px;
display:block;
}
div.paging div.disabled {
border:solid 1px #DEDEDE;
color:#888888;
display:block;
float:left;
font-weight:bold;
margin-right:2px;
padding:3px 4px;
}
ul.pagination .next a,
ul.pagination .previous a {
font-weight:bold;
}
ul.pagination .current{
background:#2e6ab1;
color:#FFFFFF;
font-weight:bold;
display:block;
float:left;
padding:4px 6px;
}
ul.pagination a:link,
ul.pagination a:visited {
color:#0e509e;
display:block;
float:left;
padding:3px 6px;
text-decoration:none;
}
ul.pagination a:hover{
border:solid 1px #0e509e
}

You should then have something that looks like this

CakePHP Style Pagination

And thats it!

Any trouble, leave a comment and we’ll try and sort it out.
