问题描述
我正在尝试使用update_post_Meta函数将序列化的数据插入wp_postMeta表中。
但是，当我将数据插入表中时，它正在被更改。例如，这是我要插入的内容：
update_post_Meta($Feed_id,'wpRSS_ftp_taxonomies','a:3:{i:0;a:6:{s:8:"taxonomy";s:6:"source";s:5:"terms";a:1:{i:0;s:3:"'.$source_slug.'";}s:4:"auto";s:5:"false";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}i:1;a:6:{s:8:"taxonomy";s:5:"topic";s:5:"terms";s:0:"";s:4:"auto";s:4:"true";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}i:2;a:6:{s:8:"taxonomy";s:10:"categories";s:5:"terms";s:0:"";s:4:"auto";s:5:"false";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}}');
所以我的序列化数据是这样的：
a:3:{i:0;a:6:{s:8:"taxonomy";s:6:"source";s:5:"terms";a:1:{i:0;s:3:"'.$source_slug.'";}s:4:"auto";s:5:"false";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}i:1;a:6:{s:8:"taxonomy";s:5:"topic";s:5:"terms";s:0:"";s:4:"auto";s:4:"true";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}i:2;a:6:{s:8:"taxonomy";s:10:"categories";s:5:"terms";s:0:"";s:4:"auto";s:5:"false";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}}
但是它是这样插入数据库的：
s:577:"a:3:{i:0;a:6:{s:8:"taxonomy";s:6:"source";s:5:"terms";a:1:{i:0;s:3:"abc";}s:4:"auto";s:5:"false";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}i:1;a:6:{s:8:"taxonomy";s:5:"topic";s:5:"terms";s:0:"";s:4:"auto";s:4:"true";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}i:2;a:6:{s:8:"taxonomy";s:10:"categories";s:5:"terms";s:0:"";s:4:"auto";s:5:"false";s:14:"filter_subject";s:0:"";s:15:"filter_keywords";s:0:"";s:28:"post_taxonomy_compare_method";s:3:"all";}}";
看起来像是将其作为字符串插入，而不仅仅是将值设置为我输入的原始序列化数据。
我不知道如何纠正此问题，因为我不经常直接使用序列化数据。
任何见识都会受到赞赏。
解决方法
您可以“反序列化”，它将正常运行
$data = unserialize( 'YOUR_CODE_SERIALIZED_HERE' );
update_post_meta($feed_id,'wprss_ftp_taxonomies',$data);
