I was wondering if its possible to add a little box, like the 'excerpt' box to all posts in wordpress so that i can enter a URL.
Cheers,
You can use the add_meta_box function. You also need a callback function that outputs the form html on the post screen and a save function.
Here is a basic example that adds a URL meta box to lower right hand side of the post screen.
add_action( 'add_meta_boxes', 'c3m_sponsor_meta' );
function c3m_sponsor_meta() {
add_meta_box( 'c3m_meta', 'Sponsor URL Metabox', 'c3m_sponsor_url_meta', 'post', 'side', 'high' );
}
function c3m_sponsor_url_meta( $post ) {
$c3m_sponsor_url = get_post_meta( $post->ID, '_c3m_sponsor_url', true);
echo 'Please enter the sponsors website link below';
?>
<input type="text" name="c3m_sponsor_url" value="<?php echo esc_attr( $c3m_sponsor_url ); ?>" />
<?php
}
add_action( 'save_post', 'c3m_save_project_meta' );
function c3m_save_project_meta( $post_ID ) {
global $post;
if( $post->post_type == "post" ) {
if (isset( $_POST ) ) {
update_post_meta( $post_ID, '_c3m_sponsor_url', strip_tags( $_POST['c3m_sponsor_url'] ) );
}
}
}
Edit: Corrected namespace error in code above.
