获取iframe变量url的值

Question

I would like to help see the example:

http://www.siteexemple.com/pagina.php?url=http://www.variablevalue.com

In my php: pagina.php I have the iframe:

 <Iframe src = "" width = "100%" height = "100%" scrolling = "no" frameborder = "0" allowFullScreen = "true"> </ iframe>

Now how do I get the value of the variable `` urlto the iframe src = ""

the result I would like to get is:

 <Iframe src = "http://www.variablevalue.com" width = "100%" height = "100%" scrolling = "no" frameborder = "0" allowFullScreen = "true"> </ iframe>

Already tried:

 <Iframe src = "<? Php echo $ url;?>" Width = "100%" height = "100%" scrolling = "no" frameborder = "0" allowFullScreen = "true"> </ iframe>

But it did not work, I thank you in advance for attention thank you!

Answer 1

Use $_GET["url"] instead of $url.

<Iframe src = "<?php echo $_GET["url"]; ?>" Width = "100%" height = "100%" scrolling = "no" frameborder = "0" allowFullScreen = "true"> </ iframe>

Just a note that if you contain un-encoded URL as variables might cause some escape exceptions. I'll suggest to use urlencode() and urldecode() to process these variants in advance.
