php绑定引号在html中

I have following code in php where I am binding html code:

 $my_doc.="<img src='mysite.in/$myDoc->my_doc_name' onclick='window.open(".$base_image_url.$myDoc->my_doc_name.")' value='".$myDoc->my_doc_id."' class='cropcss'/>";

It produces following output:

<img src="mysite.in/8422_1477013411.png" onclick="window.open(mysite.in/8422_1477013411.png)" value="623" class="cropcss">

In window.open(mysite.in/8422_1477013411.png) I have missed single quote inside. How do I add this?

I prefer to use single quotes for outputting variables like HTML to the browser. Simply use \' to escape a single quote, and pass it to the browser. Something like this should work:

$my_doc .= '<img src="mysite.in/' . $myDoc->my_doc_name . '" onclick="window.open(\'' . $base_image_url . $myDoc->my_doc_name . '\')" value="' . $myDoc->my_doc_id . '" class="cropcss" />";

If you insist on using double quotes, a minor quick change can fix this (Just add \" around your text):

$my_doc.="<img src='mysite.in/$myDoc->my_doc_name' onclick='window.open(\"".$base_image_url.$myDoc->my_doc_name."\")' value='".$myDoc->my_doc_id."' class='cropcss'/>";

For more info, see this post on how to escape quotation marks in php

check code replace this

$my_doc.="<img src='mysite.in/$myDoc->my_doc_name' onclick='window.open('".$base_image_url.$myDoc->my_doc_name."')' value='".$myDoc->my_doc_id."' class='cropcss'/>";

As an alternative - you can use HEREDOC syntax - keeps it nice and neat in the output code, no need to worry about escaping quote marks or breaking/concatenating the string.

$my_doc .= <<<MYDOC
<img src="mysite.in/{$myDoc->my_doc_name}" onclick="window.open('{$base_image_url}{$myDoc->my_doc_name}')" value="{$myDoc->my_doc_id}" class="cropcss" />
MYDOC;
