get_postsテンプレ
$conditions = array( 'post_type' => 'カスタム投稿タイプ', 'posts_per_page' => -1,//-1:全て取得する 'post_status' => 'publish', 'orderby' => 'date', 'order' => 'DESC', 'tax_query' => array( array( 'taxonomy' => 'タクソノミー', 'field' => 'slug', 'terms' => 'ターム', ) ), ); $posts = get_posts($conditions);
<?php foreach($posts as $post):?>
<?php endforeach; wp_reset_postdata();?>
カラム名一覧取得
application/core/MY_Model.phpとかに追記
public function get_column_names($table = '', $format = '%s') { $names = $this->db->list_fields(empty($table) ? $this->name : $table); if(!empty($format)){ foreach($names as &$name){ $name = sprintf($format,$name); } } return $names; }
wp-config.php
define('SAVEQUERIES', true);
テンプレート内
global $wpdb; var_dump($wpdb->queries);
記事を表示する最小処理
<?php //各環境に合わせて修正 require( dirname( __FILE__ ) . '/../../wp-blog-header.php' ); //表示する件数 $per_page = 4; query_posts(array('posts_per_page'=>$per_page,'post_status'=>'publish')); ?> <?php if(have_posts()):while(have_posts()):the_post(); ?> <div> <?php $custom_fields = get_post_custom();?> <p><?php the_time('Y/m/d');?></p> <a href="<?php the_permalink();?>"><?php the_title();?></a> <p><?php the_content();?></p> </div> <?php endwhile;endif;?>
テーブルのカラムのコメント取得
/application/core/MY_Model.phpとかに実装
public function get_column_comments($table = '') { if(empty($table)){ $table = $this->name; } $query = "SELECT COLUMN_NAME,COLUMN_COMMENT FROM INFORMATION_SCHEMA.COLUMNS WHERE table_name = '$table' AND table_schema = '{$this->db->database}'"; $result = $this->db->query($query); $result = $result->result('array'); $tmp = array(); foreach($result as $array){ $tmp[$array['COLUMN_NAME']] = $array['COLUMN_COMMENT']; } return $tmp; }
カスタムフィールドのファイル
$cf = get_post_meta($post->ID); $file_info = get_file_info_by_attachment_id($cf['cf_pdf'][0]);
/** * カスタムフィールドのファイル項目のIDからファイルの情報を返す * @param $attachment_id * @return string */ function get_file_info_by_attachment_id($attachment_id){ $file_url = wp_get_attachment_url($attachment_id); $upload_dir = wp_upload_dir(); $file_path = realpath($upload_dir['path'] . DIRECTORY_SEPARATOR . basename($file_url)); $result = array( 'url' => $file_url, 'path' => $file_path, 'realsize' => filesize($file_path), ); return $result; }
pagination
テーマのfunctions.phpに入れておくとよい。
function echo_pagination($params = array()){ $params = array_merge( array( 'per_page' => 6, 'link_count' => 9, 'left' => '<li><a href="%url%">◀</a></li>', 'right' => '<li><a href="%url%">▶</a></li>', 'format' => '<li><a href="%url%">%no%</a></li>', 'current_format' => '<li class="active"><a href="%url%">%no%</a></li>', ), $params ); global $paged; global $wp_query; if(empty($paged)){ $paged = 1; } $pages = $wp_query->max_num_pages; if(!$pages){ return; } if(1 < $paged){ echo preg_replace('/%url%/',get_pagenum_link($paged-1),$params['left']); } $startPageNo = max(1, $paged-floor($params['link_count']*0.5)); if($pages-$params['link_count'] < $startPageNo){ $startPageNo = $pages-$params['link_count']+1; } for($i=$startPageNo;$i<$startPageNo+$params['link_count'] && $i <= $pages;$i++){ $html = preg_replace('/%url%/',get_pagenum_link($i),$params[($i==$paged)?'current_format':'format']); echo preg_replace('/%no%/', $i, $html); } if($paged < $pages){ echo preg_replace('/%url%/',get_pagenum_link($paged+1),$params['right']); } }
404自動リダイレクトOFF
