将父窗口的变量获取到iframe网址

Question

I'm trying to pass on the parent url variables to the variables of the iframe url.

For example if the parent url is: http://mywebsite.com/autos-zoeken?sessid=s838c7e5c3be0452fc38f4ffb6f307ed7&code=be3f&whsearch_key=6568

The iframe url needs to become: http://anotherwebsite.com/s838c7e5c3be0452fc38f4ffb6f307ed7/be3f/stock/6568/

The code I'm using now is:

<?php $val1 = $_GET[“sessid“]; $val2 = $_GET[“code“]; $val3 = $_GET[“whsearch_key“]; echo "<iframe src='http://anotherwebsite.com/' . $val1 . '/' . $val2 . '/stock/' . $val3 . '/' id='blockrandom' width='1000' height='1200' scrolling='auto' frameborder='0' class='wrapper'> Your browser doesn't support inline frames.</iframe>"; ?>

The result on the website is: http://anotherwebsite.com/' . . '/' . . '/stock/' . . '/' id='blockrandom1' etc

So the variables aren't being put in the right place in the iframe url

What am I doing wrong here?

Answer 1

this should work fine:

echo "<iframe src='http://anotherwebsite.com/$val1/$val2/stock/$val3/' id='blockrandom' width='1000' height='1200' scrolling='auto' frameborder='0' class='wrapper'> Your browser doesn't support inline frames.</iframe>";

the problem is with all your quote's inside your src, it thinks it needs to stop your src after http://anotherwebsite.com/ and you don't need to use "." inbetween because you used doubleqouote on start, you can just use variables inside doublequotes.

    echo "<iframe src='http://anotherwebsite.com/$val1/$val2/stock/$val3/' id='blockrandom' width='1000' height='1200' scrolling='auto' frameborder='0' class='wrapper'>Your browser doesn't support inline frames.</iframe>"; ?>

You're not actually concatenating multiple strings, you're just building a single string. Take a look at a simplified example:

"<iframe src='http://anotherwebsite.com/' . $val1"

That's just one string which happens to have a period between some spaces. In order to use the . concatenation operator you need to terminate the string first:

"<iframe src='http://anotherwebsite.com/'" . $val1
