Hey All, Need to pass the current window width to a PHP class which creates a slide show presentation. The presentation image sizes need calculated for all devices including mobile and smart phone (mobile web). Problem is, PHP is server side and doesn't care about the windows width. I'm using Javascript to acquire the window width and pass that value to PHP - before calling the class that create the presentation. My workaround is using Output Buffering: <php ob_start(); //starts buffering ?> <script> var wwidth = screen.width; document.write(wwidth): //output </script> <?php $windowwidth = ob_get_clean(); //works error_log("Window width is: ".$windowwidth); //continue on with the rest of the script ?> I dislike ducking in and out of PHP like this. And I'm not able to use Javascript XMLHttpRequest because I need the size before the class is called, on the current page. Any alternative suggestions? Thanks in advance -
I have seen a couple of other threads relatively similar but I still find my problem unique so I hope you guys give me a chance. What I want to do: use proxy to bypass same origin policy and to save these values (that changes and need to be checked by timer) into variables that can be modified. A server contains data.asp which looks something like this and updates from time to time (although with a bit more data): { "Title":"Tile of song" ,"Artist":"The artist" ,"Album":"The album" ,"CDCover":"/covers/randomcover.jpg" } The method I have tried is like the one on http://qnimate.com/same-origin-policy-in-nutshell/#Same_Origin_Policy_for_AJAX. In case you guys don't want to follow the link I've posted the data here as well. <script> function loadXMLDoc() { var xmlhttp; if (window.XMLHttpRequest) { xmlhttp=new XMLHttpRequest(); } else { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("myDiv").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","http://www.qnimate.com/ajaxdata.php",true); xmlhttp.send(); } </script> </head> <body> <button type="button" onclick="loadXMLDoc()">Request data</button> <div id="myDiv"></div> And the proxy file: <?php echo file_get_contents('http://www.qscutter.com/ajaxdata.txt'); ?> So what I want to do is store the data into variables that I can alter, not show it inside a div using innerHTML. Preferably check this ever so often for changes as well. Suggestions? I can add that I have the permission from the server owner to retrieve the information and to use it but no possibility to add script to their server, hence the proxy bypass attempt.
