Warning: Cannot modify header information - headers already sent by (output started at /var/html/dev/wp/wp-content/plugins/crayon-syntax-highlighter/crayon_langs.class.php:340) in /var/html/dev/wp/wp-content/plugins/crayon-syntax-highlighter/crayon_wp.class.php on line 220So you have this function which is supposed to use the first image in an “image”-post automagically as featured image. But it doesn’t. It uses the last image.
I hacked the
functions.phpto be sure to use the first image.In your functions.php find the line where it says
function pinboard_get_first_image() {Replace the whole function (until the closing “}” briefly before the “endif;”-tag) with:
function pinboard_get_first_image() {
$document = new DOMDocument();
$content = apply_filters( 'the_content', get_the_content( '', true ) );
if( '' != $content ) {
libxml_use_internal_errors( true );
$document->loadHTML( $content );
libxml_clear_errors();
$images = $document->getElementsByTagName( 'img' );
$document = new DOMDocument();
$images_amount = ($images->length); // How many images are there in the post?
if( $images->length ) {
$image= $images->item( $images->length - $images_amount ); // The first image ist the 0 (zero).
$src = $image->getAttribute( 'src' );
$width = ( $image->hasAttribute( 'width' ) ? $image->getAttribute( 'width' ) : false );
$height = ( $image->hasAttribute( 'height' ) ? $image->getAttribute( 'height' ) : false );
return array( $src, $width, $height );
}
}
return false;
}
The changes I made are concerning the variable$images_amount.
