fpdf page break issue
提问by Claudiu Creanga
I have this loop that prints 6 rows (multicell) for about 30 times. The issue is that when it reaches the bottom page it prints 2 or 3 rows from the multicell and on the next page it prints the other 3 rows. I want to make it print all 6 rows on the next page if there is not enough space for all 6 rows on the present page. I use this code:
我有这个循环打印 6 行（多单元格）大约 30 次。问题是，当它到达底部页面时，它会从多单元格打印 2 或 3 行，并在下一页打印其他 3 行。如果当前页面上的所有 6 行没有足够的空间，我想让它在下一页上打印所有 6 行。我使用这个代码：
$height_of_cell = 60; mm
$page_height = 279.4; // mm (portrait letter)
$bottom_margin = 20; // mm
$space_left = $page_height - $p->GetY(); // space left on page
$space_left -= $bottom_margin; // less the bottom margin
if ( $height_of_cell >= $space_left) {
$p->Ln();
$p->AddPage(); // page break
$p->Cell(100,5,'','B',2); // this creates a blank row for formatting reasons
}
but it doesn't work. Any solutions? Thanks!
但它不起作用。任何解决方案？谢谢！

Use GetYto get the current position, subtract it from the height of your document. If that is less than 6x (you have 6 rows) your multicell height, then force a page break by using AddPage.
使用GetY获取当前位置，从文档的高度中减去它。如果它小于多单元格高度的 6 倍（您有 6 行），则使用AddPage强制分页。
I know you fixed this, but for the benefit of anyone else, this should give a broad idea.
我知道你解决了这个问题，但为了其他人的利益，这应该提供一个广泛的想法。
<?php
$p = new FPDF();
$p->AddPage();
$p->SetFont('Arial','B',16);
$p->SetAutoPageBreak(false);
$height_of_cell = 60; // mm
$page_height = 286.93; // mm (portrait letter)
$bottom_margin = 0; // mm
for($i=0;$i<=100;$i++) :
$block=floor($i/6);
$space_left=$page_height-($p->GetY()+$bottom_margin); // space left on page
if ($i/6==floor($i/6) && $height_of_cell > $space_left) {
$p->AddPage(); // page break
}
$p->Cell(100,10,'This is a text line - Group '.$block,'B',2);
endfor;
$p->Output();
?>
