Echo custom fields in any category

Published

on

Here is a neat trick. Say you want to show a custom field in you post or in a certain categories post. There is a simple code you need to write in order to accomplish this:

<?php $image = get_post_meta($post->ID, "image", $single = true); ?>
<?php if($image != '') : if(in_category(7)) { echo ''; } else { ?>
<img src="<?php echo $image ?>" alt="<?php the_title(); ?>" /></a>

In the example above I am calling the variable $image and telling the server that it equals the value of “image” inside get_post_meta or “custom field” of the current post.

Then we are asking if that variable $image doesn’t equal nothing or != and if it is in the category id of 7, echo what ever is in the single quotes (which is nothing in this example), otherwise show the <img> and the value inside “image” which should be the location of the image.

Update: Thanks to Austin from PressedWords for pointing out his trick, from the comment below.

    No need to call get_post_meta() twice. Save some CPU cycles and echo the $image variable instead for the image src attribute.

Remove spaces when echoing the_title

Ever wanted to print or echo the WordPress title attribute without spaces?

Published

on

This little trick can be useful for calling custom functions and printing the title with out spaces for W3C compatibility. I used this trick in a new theme called Galleria, which will be out for public download in the coming days.

Using this comes in handy for a delicious text link:

<?php $title = get_the_title(); ?>
<a href="http://del.icio.us/post?url=<?php echo $title; ?>&amp;<?php echo str_replace(" ", "%20", $title); ?>">
Bookmark This (<?php echo $title; ?>)</a>

What I am doing is calling $title = get_the_title(); and using str_replace(" ", "%20", $title); to replace empty spaces with a %20, which is used in URL encoding empty spaces.

Alternatively you can use a dash or underscore.

Thanks to Jason Boyle for his adaption.

Display the_excerpt only if there is text

Have you ever wanted to display the excerpt only if you write one? A simple couple lines of code can display the_excerpt any where you like.

Published

on

In my new theme, I am using this coded trick to display the excerpt on a single post only if I’ve got text inside. Usually if you use the_excerpt and you don’t have one, it will fake one for you.

This is not something that I wanted to do on the single post page. So I used the following code to check if the excerpt existed.

if ( !empty( $post->post_excerpt ) ) :

Once this action is taken into account, you can factor in what code you want to out put if the post_excerpt isn’t empty.

if ( !empty( $post->post_excerpt ) ) :
	the_excerpt();
else :
	false;
endif;

The above code checks if there is an excerpt and print’s it to the screen. If there isn’t an except, it doesn’t do anything.

This is a simple one.

/**
 * Your Blog title

function my_blog_title() {

    return '<span class="blog-title">' . $blogname . '</span>';
}
