我的if语句无法正常工作

if语句无法正常工作，它将正确打印一页，然后打印另外17页没有列标题和仅一个数据行。我一直无法弄清楚这种方式无法正常工作。有一个更好的方法吗。我正在做FPDF网站的休息处理。我的if语句无法正常工作

我不是从移除错误除了触摸原始代码和检查分页符是否正常工作。我会去看看它，看看我能否理解它。我会以某种关于它的信息回复你。它可能是明天，因为它在这里傍晚。我之前没有玩过pdf输出，所以我正在学习新的东西。 –

变化if ($i == $max){到if ($i != 0 && $i % $max == 0) { 这将执行新的,,页'每25记录$i != 0在那里，以确保新的一页难道不被添加到第1条记录。

这没什么大错。一些未定义的变量。我已经改变了一些变量的名称，但没有什么不对的，我可以发现原来的。

我没有安装'Arial'字体，因为我刚刚下载并安装了原始的'tcpdf'软件。

它现在分页正确。

它比以前更好用了，现在不用做了。但它仍然不会在第二页上正确分裂，它看起来像添加了25个空行，然后打印下一行25行。然后它会创建第3页，因为是第二组线出现。每创建一个新页面，它也会向左移动一点点。这是一个链接，所以你可以看到http://notaryaccounting.com/expencetest1.pdf –

我的第一个地方后，把所有的数据一路下滑的页面上所有其他网页的页面想出办法。在Ryan Vincent答案的帮助下，他帮助我用上面的例子打印了17页脚本。我仍然有一个问题，它是把所有的数据方式放在页面上。所以，正确的后

if ($pageLine >= $itemsPerPage) { 

     $pdf->AddPage();\

我加

$y_axis = 20; //reset Y_axis to move the data back to the top of the NEW page 
         //under the columns

这是所有花了现在的脚本工作完美

$pdf = new PDF(); 
$pdf->AddPage ($orientation='', $format='', $keepmargins=false, $tocpage=false);
