我想以Quote post格式从帖子中获取第一个blockquote（即使用户只写了一个或多个），以便在归档循环中显示它。例如：
$quote = has_post_format( \'quote\' );
if ( $quote ) {
if ( *the post has no quotes* ){
// Don\'t show anything
} else {
// Show the blockquote from the post (if there\'s only one),
// or the first one (if there are more than 1)
}
}
我终于找到了一个可行的解决方案。如果您需要，请在这里：
<?php
if (has_post_format(\'quote\', $post->ID)) {
$content = trim(get_the_content());
// Take the first quote from the content
$quote_string = extract_from_string(\'<blockquote>\', \'</blockquote>\', $content);
// Make sure there\'s a quote on the content
if (!$quote_string == "") {
// Get the first quote and show it on the Loop
echo $quote_string;
} else {
// If not, show nothing
}
}
?>
尝试以下操作：
<?php
// Check is post has quote format
if (has_post_format(\'quote\', $post->ID)) {
$content = trim(get_the_content());
// Make sure content isn\'t empty
if (!$content == "") {
// Take each new line and put into an array (for multiple quotes)
$quote_array = explode( "\\n", $content);
// Get the first quote and do something with it
$first_quote = array_shift( $quote_array );
echo $first_quote;
}
}
?>
