I am trying to pass a url for creating an iframe as a parameter of a query string. Because the url that I am passing contains an ampersand, I encode the url with 'urlencode' then append it to the query string.
<?php
$url = "http://www.somesite.com/index.php?option=content&view=article&id=1234:some+article";
$url_encoded = urlencode($url);
?>
<a href="http://www.mysite.com/external_article_iframe/?url=<?php echo $url_encoded ?>" target="_blank"></a>
On the page where I want to create the iframe, I retrieve the url parameter using the $_GET variable.
<?php
$iframe_source = $_GET[$url];
?>
<iframe id="external-link-frame" src="<?php echo $iframe_source ?>"></iframe>
However $_GET only retrieves the part of the parameter value up to the encoded ampersand.
<?php echo $_GET[$url]; //outputs http://www.somesite.com/index.php?option=content ?>
What must I do in order to send the entire url including the parameters that are part of its own query string.
UPDATE: I am able to do it by encoding the url twice
urlencode(urlencode($url));
Take a look at: https://stackoverflow.com/a/2433211/1359529
I think rawurlencode() will encode the ampersands too.
I believe, how you append it, the $_GET function thinks that the ampersand signs are signifying new values to get. I bet if you did after that $iframe_view = $_GET[$view] it will output article.
If you want it to get the full URL, I think it's best to encode by replacing & signs with something else and then once you get the url, then replace them back to & signs.
