Php TCPDF在多个页面上拆分html表
我使用TCPDF输出html表,在我的示例中,这个表不是唯一需要修改的表,所以我需要一些规则来呈现我的页面。 到目前为止,TCPDF在我看来是一个功能强大的库,所以我希望不要尝试另一个 我的问题是,我需要将表格标题添加到表格显示的每个新页面,但我还有其他信息要写入此pdf,这些信息必须没有表格标题,因此我无法在tcpdf中使用“重写标题”方法Php TCPDF在多个页面上拆分html表,php,html,html-table,tcpdf,Php,Html,Html Table,Tcpdf,我使用TCPDF输出html表,在我的示例中,这个表不是唯一需要修改的表,所以我需要一些规则来呈现我的页面。 到目前为止,TCPDF在我看来是一个功能强大的库,所以我希望不要尝试另一个 我的问题是,我需要将表格标题添加到表格显示的每个新页面,但我还有其他信息要写入此pdf,这些信息必须没有表格标题,因此我无法在tcpdf中使用“重写标题”方法 <table border="0" cellspacing="0" cellpadding="0" align="center" width="10

我想到了以下解决方案:如果我能将这个html拆分成行,并逐行写入pdf,这样当我在页脚上写入时可以回滚,然后添加一个新页面,但有一个主要问题,我会收到各种各样的警告,因为html表标记没有关闭。
这是我的密码:
$pdf->setAutoPageBreak(false);
$pdf->startTransaction();
$html = new simple_html_dom();
$html->load($data);
$single = $html->find('#Container', 0);
if($single){
$rows = $single->getElementsByTagName('tr');
$rows = $rows[0]->getElementsByTagName('tr');
if($rows)
for($i=1;$i<(count($rows)-1);$i++){
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', '<table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $rows[$i]->outertext, $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', '</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
if ($pdf->getY() > $pdf->getPageHeight() - 30) {
$pdf->rollbackTransaction(true);
$pdf->AddPage();
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', '<table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $rows[$i]->outertext, $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', '</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
}
}
}
$pdf->commitTransaction();
$pdf->setAutoPageBreak(true, 30);
$pdf->setAutoPageBreak(false);
$pdf->startTransaction();
$html=新的简单html\U dom();
$html->load($data);
$single=$html->find(“#容器”,0);
若有($单){
$rows=$single->getElementsByTagName('tr');
$rows=$rows[0]->getElementsByTagName('tr');

对于($i=1;$iwriteHTMLCell($w=0,$h=0,$x='',$y='',$border=0,$ln=1,$fill=0,$reseth=true,$align='',$autopadding=false);

我快速浏览了这两篇文章,也许有人会发现这很方便:
还有。我发现这2个值得作为解决方案逻辑的一个例子,但在我看来,tcpdf使用的方法有点奇怪。我认为你的解决方案是一个很好的解决方案。我唯一能想到的另一种方法是使用固定宽度的多单元,这可能会很痛苦,但会给你静态的列宽 然而,我注意到一些问题:
$pdf->setAutoPageBreak(false);
//$pdf->startTransaction(); // Moved
$html = new simple_html_dom();
$html->load($data);
$single = $html->find('#Container', 0);
if($single){
$rows = $single->getElementsByTagName('tr');
$rows = $rows[0]->getElementsByTagName('tr');
if($rows) {
$pdf->startTransaction(); // Start transaction only because we may need it
// Header for html, this starts the html and can optionally insert the header row as the first row on every new page.
$html_header = '<tr><td>Name</td><td>Age</td></tr>';
$html_buffer = '<table>'.$html_header;
for($i=1;$i<(count($rows)-1);$i++){
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $html_buffer.$rows[$i]->outertext.'</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
if ($pdf->getY() < ($pdf->getPageHeight() - 30)) { // Note the less-than operator
// We might be able to add some more text, so undo that
$pdf->rollbackTransaction(true);
// And store the html
$html_buffer .= $rows[$i]->outertext;
}else{
// We exceeded our limit
$pdf->rollbackTransaction(true);
// Write last known good table
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $html_buffer.'</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
// Add a new page
$pdf->AddPage();
// End this transaction
$pdf->commitTransaction();
// Start a new transaction
$pdf->startTransaction();
// Reset html buffer
$html_buffer = '<table>'.$html_header;
// Add line we couldn't fit on last page to html buffer
$html_buffer .= $rows[$i]->outertext;
}
}
// There is still information in our buffer and it fits on a single page
$pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $html_buffer.'</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
// Final commit
$pdf->commitTransaction();
}
}
$pdf->setAutoPageBreak(true, 30);
$pdf->setAutoPageBreak(false);

$rows=$single->getElementsByTagName('tr');
$rows=$rows[0]->getElementsByTagName('tr');

$pdf->startTransaction();//仅因为我们可能需要启动事务
//对于html,这将启动html,并且可以选择在每个新页面上插入标题行作为第一行。
$html_头='NameAge';
$html\u buffer='.$html\u头;
对于($i=1;$iwriteHTMLCell($w=0,$h=0,$x='',$y='',$html\u buffer.$rows[$i]>outertext.',$border=0,$ln=1,$fill=0,$reseth=true,$align='',$autoadding=false);
如果($pdf->getY()<($pdf->getPageHeight()-30)){//请注意小于运算符
//我们可能会添加更多的文本,所以请撤消该操作
$pdf->rollbackTransaction(true);
//并存储html
$html\u buffer.=$rows[$i]->outertext;
}否则{
//我们超出了限制
$pdf->rollbackTransaction(true);
//写下最后一个已知的好表
$pdf->writeHTMLCell($w=0,$h=0,$x='',$y='',$html\u buffer'',$border=0,$ln=1,$fill=0,$reseth=true,$align='',$autopadding=false);
//添加新页面
$pdf->AddPage();
//结束此交易

$pdf->writeHTMLCell($w=0,$h=0,$x='',$y='',$html\u buffer'',$border=0,$ln=1,$fill=0,$reseth=true,$align='',$autopadding=false);
//最后承诺
$pdf->commitTransaction();
}
}
$pdf->setAutoPageBreak(true,30);
这会将页面上的所有内容包装在一个表块中,以便列在该页面上对齐。(但是,每一页的列可能仍然不同)此外,我给了您t
