[WordPress] WP_ALLOW_REPAIR の罠

http://example.com/wp-admin/maint/repair.php を有効にするには wp-config.php に以下を追記します。

define('WP_ALLOW_REPAIR', true);

これを無効にしようとして define('WP_ALLOW_REPAIR', false); としてもダメです。コメントアウトするか行自体を削除しないといけない。
なぜなら wp-admin/maint/repair.php で以下のように判定してるから。

 :
if ( ! defined( 'WP_ALLOW_REPAIR' ) ) {
        echo '
' . __( 'To allow use of this page to automatically repair database problems, please add the following line to your wp-config.php file. Once this line is added to your config, reload this page.' ) . "
define('WP_ALLOW_REPAIR', true);
";
} elseif ( isset( $_GET['repair'] ) ) {

Re: [WordPress]コピペでOK！カテゴリー、タグ、パンクズを呼び出すサンプルコードいろいろ

さらっと流し読みしただけですが…

現在読み込んでいる記事の、カテゴリーリンクを1つ出力します。記事が属するカテゴリーが1つだけの場合に有効です。記事一覧を表示するループ内などで使うのが一般的です。
その1. サンプルコード

    $cat = get_the_category();
    echo '<a href="'.get_category_link($cat[0]->term_id).'">'.$cat[0]->name.'</a>';

[WordPress]コピペでOK！カテゴリー、タグ、パンクズを呼び出すサンプルコードいろいろ

get_the_cateory() ですが、内部的には get_term() を呼び出してます。
そんで get_term() では、なにがしかのエラーがあった場合 WP_Error オブジェクトを返すことがあるので、このまま使うと WP_Error オブジェクトが返ってきたときに $cat[0]->term_id とかが存在せずにエラーになってしまいます…
( see. https://core.trac.wordpress.org/browser/tags/3.8/src/wp-includes/taxonomy.php#L933 )

そんなわけで、get_the_category() の返り値は is_wp_error() で検査してから使った方が幸せになれると思うよ。
# ってか the_category() とか標準のテンプレートタグ使えば良いのに…

[WordPress] 「おやおや」と「こどもも」

親カテゴリー「おやおや」とその子カテゴリー「こどもも」があるとします。WordPressでは子カテゴリー「こどもも」にチェックを入れた場合、親カテゴリー「おやおや」にはチェックが入りません。これを親カテゴリーにも自動的にチェックを入れるプラグイン(Parent Category Toggler)はあるのですが、これを過去分にさかのぼってチェックを入れるには？


INSERT INTO wp_term_relationships
SELECT object_id, term_taxonomy_id, 0 AS term_order
FROM (
SELECT DISTINCT r.object_id, p.term_taxonomy_id
FROM wp_term_relationships AS r
INNER JOIN wp_term_taxonomy AS t ON r.term_taxonomy_id = t.term_taxonomy_id

WHERE t.taxonomy = 'category'
AND t.parent > 0 ) AS a
