Tell us what you are trying to do?
I want to use an image from a custom field as meta property
What is the link to your site? lien caché
I saw: <meta property="og:url" content="<?php do_shortcode('[types field='affiliate-url' output='raw'][/types]'); ?>" /> but I don't know where to put it....
I found single.php, header.php and dynamic-header.php, i tried to put the code " <meta property="og:image" content="<?php echo types_render_field('image-a-mettre-a-la-une', array()) ?>" />" in all of theme without success...
Is there a way to make it with a php code in function.php ?
//Adding the Open Graph in the Language Attributes
function add_opengraph_doctype( $output ) {
return $output . ' xmlns:og="<em><u>lien caché</u></em>" xmlns:fb="<em><u>lien caché</u></em>"';
}
add_filter('language_attributes', 'add_opengraph_doctype');
//Lets add Open Graph Meta Info
function insert_fb_in_head() {
global $post;
if ( !is_singular()) //if it is not a post or a page
return;
if(!has_post_thumbnail( $post->ID )) { //the post does not have featured image, use a default image
$default_image="<?php echo types_render_field('image-a-mettre-a-la-une', array()) ?>"; //replace this with a default image on your server or an image in your media library
echo '<meta property="og:image" content="' . $default_image . '"/>';
}
else{
$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'medium' );
echo '<meta property="og:image" content="' . esc_attr( $thumbnail_src[0] ) . '"/>';
}
echo "
";
}
add_action( 'wp_head', 'insert_fb_in_head', 5 );
function insert_fb_in_head() {
global $post;
if ( !is_singular()) //if it is not a post or a page
return;
if(!has_post_thumbnail( $post->ID )) { //the post does not have featured image, use a default image
$default_image="<?php do_shortcode('[types field='your-custom-code' output='raw'][/types]'); ?>"; //replace this with a default image on your server or an image in your media library
echo '<meta property="og:image" content="' . $default_image . '"/>';
}
else{
$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'medium' );
echo '<meta property="og:image" content="' . esc_attr( $thumbnail_src[0] ) . '"/>';
}
echo "
";
}
add_action( 'wp_head', 'insert_fb_in_head', 5 );
it worked but only once.... im so disapointed :-[ but how can i make it work, and another question can i make it work only for a specific post type....
