PHP FPDF分頁符不起作用
[英]PHP FPDF page break not working
問題描述
我的拼貼項目結束時我正在嘗試編寫一個使用FPDF生成PDF文件的腳本。
該腳本應查詢數據表並從一個表返回作業數據，並從另一個表返回作業注釋。 這一切都有效。
然后我按行輸出每個作業，每頁最多25行（橫向）。 這一切都有效。 在輸出所有作業之后，我需要在作業數據下面輸出注釋數據。
這有效，但評論數據不會在頁面底部之前分頁。 任何人都可以看到我出錯的地方。 在我認為錯誤的地方，我用// *****標記了下面的腳本。 我知道劇本很長但我認為它可以更好地解釋我的問題。

首先，您的數據有問題，因此我更正了您的數據並解決了您的問題（ 請參閱結果 ）：

您需要使用嵌套循環，因為您的數據是嵌套的。 您應該使用嵌套的foreach循環，而不是使用while 循環 。 起初，變量名稱令人困惑，但后來我明白了你想要實現的目標。
每頁阻止一定數量評論的控制流程大多是正確的。 但是有一個錯字用於聲明和啟動$max_comments_per_page_ = 25; 必須是$max_comments_per_page = 25;
我更改了一些數字，例如$max_comments_per_page = 25; 至$max_comments_per_page = 10; 因為很難看出相關性。 我已經刪除了表格設計（MultiCell），因為這個問題與主題無關。 所以桌子設計由你決定。
最終，FPDF的基本（又稱強制）分頁功能實際上正在運行。 問題是你的數據和你選擇的循環。

要啟用或禁用自動分頁模式，我們可以使用SetAutoPageBreak()方法。
SetAutoPageBreak(boolean auto [, float margin])
這里第二個參數是距頁面底部的距離，該距離定義了觸發限制。 默認情況下，模式打開，邊距為2厘米。
你設置了$pdf->SetAutoPageBreak(false); 因此，您無法在頁面中獲得分頁符。
請從腳本中刪除此行，您將獲得換行符;

根據問題，它通常發生在php程序員身上。 我認為FPDF如何強制分頁這個anwer可能對你非常有用。 你應該嘗試一下。 上次我使用fpdf然后我用數據庫創建了一個簡單的pdf。 它的工作很好。 也像FPDF一樣，您也可以使用MPDF生成pdf。 嘗試使用鏈接的答案。 謝謝
