I am using the google chart to create a QR Code like below

<img src="https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http://mobile.dogoodperks.com/london/?pg=Home&couponid=<? print "$couponid&perkid=$perkid&pur=entered&city=$city"; ?>&choe=UTF-8" title="Link to Google.com" />

That one does not work and I even tried the one below

<img src="https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http://mobile.dogoodperks.com/london/?pg=Home&city=London&choe=UTF-8" title="Link to Google.com" />

But it did not work either please help! the qr code is generated however when scanned does not go to the page

I'm assuming your problem is that the querystring parameters (&city=London&..) are not appended to the url in the QR-code.

This problem can be resolved by urlencoding the url, for example:

Regular url

http://mobile.dogoodperks.com/london/?pg=Home&city=London&choe=UTF-8

Encoded url http%3A%2F%2Fmobile.dogoodperks.com%2Flondon%2F%3Fpg%3DHome%26city%3DLondon%26choe%3DUTF-8

In php this can be achieved using the urlencode-function, for your example this would be:

<?php
$qr_url = "http://mobile.dogoodperks.com/london/?pg=Home&couponid=".$couponid."&perkid=".$perkid."&pur=entered&city=".$city;
$qr_url_encoded = urlencode($qr_url);
echo '<img src="https://chart.googleapis.com/chart?chs=300x300&cht=qr&choe=UTF-8&chl='.$qr_url_encoded.'" />';
?>

You have to use echo and <?php ?> in url.

<img src="https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http://mobile.dogoodperks.com/london/?pg=Home&couponid=<?php echo "$couponid&perkid=$perkid&pur=entered&city=$city"; ?>&choe=UTF-8" title="Link to Google.com"/>
