我正在尋找編輯Gigpress代碼，以便當事件不是按藝術家分組時，他們仍然按事件日期而非藝術家姓名排序。在插件中更改「排序方式」
的Gigpress側邊欄做到這一點沒有問題，所以我想，主要的插件應該能夠被配置以某種方式做到這一點。我無法理解這一點。
插件代碼是

你是什麼具體問題？你在重寫插件時運行了哪些具體問題？你能特別說出什麼阻止你重寫它嗎？ – hakre 2012-01-12 16:41:15
@hakre我不知道如何重寫，所以'不按藝術家分組'按日期而不是按藝術家姓名來排序。我沒有從頭開始編寫插件。該插件是Gigpress。 – 2012-01-12 16:43:46
@Kelvin做我解決你的問題？如果是，請接受。謝謝。 – Rannnn 2012-01-26 08:33:27
