输入值中有多个双引号

I want to ask if it is possible to add multiple double quotes to the input value, like this:

<input value= "<iframe src="http://xxx.xx/embed?t=<?php the_title(); ?>" 
width='640' height='360'
allowscriptaccess='always' allowfullscreen='true'
scrolling='no' frameborder='0'></iframe>"

So, the whole <iframe> element is wrapped within double quotes, just as the value of the src attribute (the URL), but the URL will not be included in value.

Can this be achieved?

You can try escaping double quotation with backslash..... For more info visit How to properly escape quotes inside html attributes?

<input value= "<iframe src=&quot;http://xxx.xx/embed?t=<?php the_title(); ?>&quot; 
width=&quot;640&quot; height=&quot;360&quot;
allowscriptaccess=&quot;always&quot; allowfullscreen=&quot;true&quot;
scrolling=&quot;no&quot; frameborder=&quot;0&quot;></iframe>"
