我在我的網站上有一個'login-act'腳本處理的'login'頁面，該腳本在成功時重定向到'post'頁面。 「發佈」頁面具有鏈接以發佈各種類型的內容，例如， 「後的音頻」。 'post'頁面可以正常工作，因爲它顯示的是用戶名，如果通過身份驗證的話，但從那時起就是災難：如果一個經過身份驗證的用戶點擊'post-audio'，它會以某種方式註銷他並將其重定向到登錄頁面。但是，過了一段時間後（或者如果我在'後期音頻'腳本中進行了修改並撤消），它再次正常工作。這讓我瘋狂。你能幫我嗎？PHP頁面之間的行爲表現不正常

任何幫助表示讚賞。 （我知道我的一些代碼已經過時...我的工作就可以了:)）
在您的文件中註釋會話超時並檢查出來。 。 –
'mysql_（）'已棄用，''已棄用，您在''之前呼應''因此一般情況下我建議您重寫整個代碼 –
vicky，評論超時無效......我知道它必須處理第一個條件：if（！（isset ...我只是無法弄清楚:( – adeoba
