在给定页面的新选项卡中打开dompdf [英] open dompdf in new tab taken data from given page
问题描述
我知道至少还有两个其他类似的问题，但他们不能帮助我。
I know that there are at least two other similar questions, but they do not help me.
我有textyma和tinymce，用户写他的文本。然后有一个按钮PDF，应该创建pdf并在新标签中打开它。 pdf的内容是tinymce中的内容。
I have textarea with tinymce where user writes his text. Then there is a button "PDF" that should create pdf and open it in new tab. The content of pdf is the content in tinymce.
当用户点击按钮时，表单被提交到index.php操作。然后index.php从$ _POST变量中收集信息并创建pdf。
When user click on button, the form is submitted to index.php action. Then index.php gathers information from $_POST variable and creates pdf.
我无法将其作为正常链接在新标签页中打开。
我尝试了不同的方式。
I cannot get it to open in new tab as a normal link. I tried it in different ways.
1）我可以在同一个选项卡打开PDF，但这不是我需要的。这行打开我的pdf在同一个标签：
1) I can open PDF in the same tab, but this is not what I need. This line opens my pdf on the same tab:
$dompdf->stream('document.pdf',array('Attachment'=>0));
2）我可以在新窗口中打开它，但是浏览器警告这是弹出。客户不想要它。另一个问题是pdf存储在服务器上。我不想要它（弹出警告更重要）。这是我的代码：
2) I can open it in new window, but then browser warns that this is pop-up. Client doesn't want it. Also another problem with this is that pdf is stored on server. I do not want it (pop-up warning is more important). Here is my code:
$output = $dompdf->output();
file_put_contents('document.pdf', $output); //save pdf on server
//opens generated pdf in new window, but this creates warning for popup
echo '<script type="text/javascript" language="javascript">
window.open("http://modeles-de-lettres.org/test/saved_pdf.pdf", "_blank");
</script>';
我读过这些：
1 ）使用dompdf 在新标签页中打开PDF
1) Open PDF in a new tab using dompdf
这表明：在新标签页中打开，这取决于你如何生成PDF，但最简单的方法是提供一个带有目标属性的链接。我认为这意味着我有
This suggests: "As far as opening in a new tab. That depends on how you are generating the PDF. But the simplest way it to provide a link with a target attribute." I think this means that I have
<a href="my.pdf" target="blank"
或
<a href="my.php" target="blank"
但这不适用于
2) generate the pdf on newtab in dompdf
这是我之前实现的东西（我做了
This is something that I have implemented before (I did it without sessions), but it creats warning about popups.
推荐答案
问题是你在做什么事情的顺序。您应该从用户事件（例如单击按钮）打开新窗口。如果页面加载事件上的脚本尝试打开一个窗口，浏览器会假定它是一个不需要的弹出窗口，因为用户除了导航到页面之外没有做任何其他操作。
The problem is the order in which you're doing things. You should be opening the new window from a user event, like clicking a button. If a script on a page load event tries to open a window, the browser will presume it's an unwanted popup, since the user hasn't done anything besides navigating to the page.
可以为您工作的是为表单标签添加 target =somewhere_new属性。这样，浏览器将打开一个新的选项卡，因为没有框架/ iframe与 name =somewhere_new属性，你不必做任何特殊的服务器端，只是像使用 $ dompdf-> stream（'document.pdf'，array（'Attachment'=> 0））; 在结尾
What could work for you, is adding a target="somewhere_new" attribute to your form tag. This way, the browser would open a new tab since there's no frame/iframe with a name="somewhere_new" attribute, and you wouldn't have to do anything special in the server side, just process the data as you did before using $dompdf->stream('document.pdf',array('Attachment'=>0)); at the end
