E.g.:
PHP Code:
$post ['custom_fields'] ['thumb'] = preg_replace ( '/.*?img src="(.*?)".*?$/s', "\\1", $post ['post_excerpt'] );
$base = str_replace ( basename ( $post ['link'] ), "", $post ['link'] );
$post ['post_content'] .= strip_tags ( $post ['post_excerpt'] );
$post ['post_content'] .= "<p align=\"center\"><a href=\"" . $base . "/001.mpg" . "\"><img src=\"" . $base . "/001.jpg" . "\"></a><a href=\"" . $base . "/002.mpg" . "\"><img src=\"" . $base . "/002.jpg" . "\"></a><p>\n";
$post ['post_content'] .= "<p align=\"center\"><a href=\"" . $base . "/001.mpg" . "\"><img src=\"" . $base . "/003.jpg" . "\"></a><a href=\"" . $base . "/004.mpg" . "\"><img src=\"" . $base . "/004.jpg" . "\"></a><p>\n";
$post ['post_content'] .= "<p align=\"center\"><a href=\"" . $post ['link'] . "\"><strong>Click Here For More!</strong></a></p>\n";
