錯誤500 CakePHP 3

-2

我有一個錯誤500，我不明白。在我開始研究這個項目之前，錯誤就在這裏，因此很複雜。當我點擊按鈕打開PDF（帶有html2pdf）時，出現錯誤500。我嘗試了所有我發現的，但沒有成功。錯誤500 CakePHP 3

我不能給你發送代碼，或者可能只有幾行。從錯誤日誌

更精確：當我只寫「你好」的pdf，我沒有錯誤。只有當我嘗試獲取數據時。而當我設置PDF另一種觀點認爲（所以沒有PDF格式），它的工作原理：/

能否請您與我們分享您的日誌。運行'tail -f/var/log/apache2/error.log' – MontrealDevOne

最近的錯誤（'有些數據已經輸出了'）顯示已經有東西發送到瀏覽器，這意味着它不能開始下載PDF。確保在嘗試輸出PDF時沒有'echo'語句或類似信息 – gabe3886

我可以在哪裏找到這些信息？我是CakePHP的Junior，我在視圖中搜索，只有一個輸出。 –

這意味着你的應用正在超過60 seconds運行。這就是爲什麼它是粉碎。添加以下代碼到index.php文件中webroot目錄

<?php 
    set_time_limit (60 * 5); // 5 minutes 
?>

或在您的php.ini：

max_execution_time=300
