    <p>I need to load several websites in iframes whilst also adding a google translate plugin into each page so they can be translated. Here's my code for the insertion part:</p> <pre><code>&lt;iframe onload="googleJS1(); googleJS2(); googleJS3();" class=iframe2 src=http://localhost:8888/mysitep&gt;&lt;/iframe&gt; &lt;script&gt; function googleJS1() { var iframe = document.getElementsByTagName('iframe')[0]; var doc = iframe.contentWindow.document; var newScript = doc.createElement('div'); newScript.setAttribute("id", "google_translate_element"); var bodyClass = doc.getElementsByTagName('body')[0]; bodyClass.insertBefore(newScript, bodyClass.childNodes[0]); } function googleJS2() { var iframe = document.getElementsByTagName('iframe')[0]; var doc = iframe.contentWindow.document; var newScript = doc.createElement('script'); newScript.setAttribute("src", "http://translate.google.com/translate_a/element.js? cb=googleTranslateElementInit"); var bodyClass = doc.getElementsByTagName('head')[0]; bodyClass.insertBefore(newScript, bodyClass.childNodes[1]); } function googleJS3() { var iframe = document.getElementsByTagName('iframe')[0]; var doc = iframe.contentWindow.document; var newScript = doc.createElement('script'); newScript.setAttribute("src", "http://localhost:8888/mysite/google.js"); var bodyClass = doc.getElementsByTagName('head')[0]; bodyClass.insertBefore(newScript, bodyClass.childNodes[2]); } } &lt;/script&gt; </code></pre> <p>This works as long as the iframe target URL is on the same server. I read to bypass the same origin constraint I should set up a proxy server and pass all URL requests via the proxy. So I read up on cURL and tried this as a test: </p> <pre><code>&lt;?php function get_data($url) { $ch = curl_init(); $timeout = 5; curl_setopt($ch,CURLOPT_USERAGENT, $userAgent); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout); curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true); $data = curl_exec($ch); curl_close($ch); return $data; } $test = get_data("http://www.selfridges.com"); echo $test; ?&gt; </code></pre> <p>The basic HTML elements are loaded yet no CSS and images are loaded. Also the links still point to the original URL. I need some suggestions on how I can also pull the CSS, images and js off the target URL into a proxy and load the pages from there, making it look like it came from the same domain and ports and by passing the same origin policy. I also need the links to work in this fashion. </p> <p>e.g: </p> <pre><code>main page - http://localhost:8888/proxy.php links - http://localhost:8888/proxy.php/products/2012/shoes </code></pre> <p>Any other methods or alternatives are also welcome.</p> <p>Thanks</p>

    1. COUsing the useragent to mimic GoogleBot is probably a bad idea.

    3. COThen you don't need a useragent - curl will send one automatically.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
