trying to insert content before the post content in my functions.php – I know how to use the regular wp hooks, but unsure how to insert into other areas.
Tried this, but it kills content on any other post type:
function property_slideshow( $content ) {
if ( is_single() && 'property' == get_post_type() ) {
$custom_content="[portfolio_slideshow]";
$custom_content .= $content;
return $custom_content;
}
}
add_filter( 'the_content', 'property_slideshow' );
How do I make this conditional?
Just use the the_content
filter, e.g.:
<?php
function theme_slug_filter_the_content( $content ) {
$custom_content="YOUR CONTENT GOES HERE";
$custom_content .= $content;
return $custom_content;
}
add_filter( 'the_content', 'theme_slug_filter_the_content' );
?>
Basically, you append the post content after your custom content, then return the result.
Edit
As Franky @bueltge points out in his comment, the process is the same for the post title; simply add a filter to the the_title
hook:
<?php
function theme_slug_filter_the_title( $title ) {
$custom_title="YOUR CONTENT GOES HERE";
$title .= $custom_title;
return $title;
}
add_filter( 'the_title', 'theme_slug_filter_the_title' );
?>
Note that, in this case, you append your custom content after the Title. (It doesn’t matter which; I just went with what you specified in your question.)
Edit 2
The reason your example code isn’t working is because you only return $content
when your conditional is met. You need to return $content
, unmodified, as an else
to your conditional. e.g.:
function property_slideshow( $content ) {
if ( is_single() && 'property' == get_post_type() ) {
$custom_content="[portfolio_slideshow]";
$custom_content .= $content;
return $custom_content;
} else {
return $content;
}
}
add_filter( 'the_content', 'property_slideshow' );
This way, for posts not of the ‘property’ post-type, $content
is returned, un-modified.
