I'm sorry for the "re-save". You can write a script to help you doing this.
Regarding the datetime
field, if you set 'std' => ' '
, then when saving the post without specifying the datetime, it will save exactly as ' '
in the database. Actually, the plugin treats datetime field like a text field, unless you set 'timestamp' => true
, which converts datetime into integer. And then in that case, the value is kind of unexpected, cause ' '
is converted to incorrect value.
