acctman Posted July 9, 2009 Share Posted July 9, 2009 the alert box shows fine but i think my code where it checks the option value maybe work. <?php session_start(); ?> <script language="JavaScript"> <!-- function changeBack(form){ for (var i = 0; i < form.mySelect.options.length; i++) { if (form.mySelect.options[i].selected){ alert("Photo will be saved to your " + form.mySelect.options[i].text + " Folder"); if (form.mySelect.options[i].value = "1") { <?php ($_SESSION[phfolder] = 1); ?> } else if (form.mySelect.options[i].value = "2") { <?php ($_SESSION[phfolder] = 2); ?> } else if (form.mySelect.options[i].value = "3") { <?php ($_SESSION[phfolder] = 3); ?> } } } } --> </script> [code] Link to comment https://forums.phpfreaks.com/topic/165391-getting-option-value/ Share on other sites More sharing options...
corbin Posted July 10, 2009 Share Posted July 10, 2009 Errrrr..... JS and PHP don't work like that. At all.... PHP is executed before anything is sent to the client, and JS is executed by the client. So, that won't work. Link to comment https://forums.phpfreaks.com/topic/165391-getting-option-value/#findComment-872473 Share on other sites More sharing options...

acctman Posted July 11, 2009 Author Share Posted July 11, 2009 You can use AJAX to call a php script that sets your session variable. i was using this example that was written for me by another helpful forum member. it works fine as a standalone but when i add the code to my smarty tpl file it does not work. my guess is that it has something to do with this line var loaderphp = "<?php echo $_SERVER['PHP_SELF'] ?>"; i think the easiest fix would be to put the code below in an iframe, to stop an conflict my template file may have with it. <?php session_start(); if(!empty($_GET['session'])) { $_SESSION['phfolder'] = $_GET['session']; exit(); } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Set session</title> </head> <body> <script language="javascript"> function ajaxFunction(session) { var loaderphp = "<?php echo $_SERVER['PHP_SELF'] ?>"; var xmlHttp; try { xmlHttp=new XMLHttpRequest(); }catch(e){ try { xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); }catch(e){ try { xmlHttp=new ActiveXObject("Microsoft.XMLHTTP"); }catch(e){ alert("Your browser does not support AJAX!"); return false; } } } xmlHttp.open("GET", loaderphp+"?session="+session,true); xmlHttp.send(null); } </script> <form action="" method="post" enctype="multipart/form-data"> <select name="folder" onchange="javascript:ajaxFunction(this.value);"> <option value="" selected="selected">Select</option> <option value="1">Public</option> <option value="2">Mobile</option> <option value="3">Private</option> </select> Folder </form> <?php echo $_SESSION['phfolder']; ?> </body> </html> Link to comment https://forums.phpfreaks.com/topic/165391-getting-option-value/#findComment-873538 Share on other sites More sharing options...
haku Posted July 11, 2009 Share Posted July 11, 2009 it works fine as a standalone but when i add the code to my smarty tpl file it does not work. my guess is that it has something to do with this line var loaderphp = "<?php echo $_SERVER['PHP_SELF'] ?>"; It has nothing to do with that at all. It's because you are trying to set php sessions with javascript - you can't do that. Javascript doesn't have direct access to php, you need to do a behind the scenes call to a php script. This is called AJAX, as Crayon Violent mentioned. Link to comment https://forums.phpfreaks.com/topic/165391-getting-option-value/#findComment-873605 Share on other sites More sharing options...

haku Posted July 12, 2009 Share Posted July 12, 2009 Ah, I didn't see that the 2nd code was different. I don't know much about the smarty templating system, what do you see when you do a print source on the page? Is the javascript in there? What is the value for loader?

haku Posted July 13, 2009 Share Posted July 13, 2009 That's your problem then! I seem to recall one time reading that you had to enclose php in curly braces with smarty. So try turning this: <?php echo $_SERVER['PHP_SELF']; ?> to this {<?php echo $_SERVER['PHP_SELF']; ?>} and see if that helps.

seventheyejosh Posted July 13, 2009 Share Posted July 13, 2009 for javascript code, such as ajax calls in smarty you have to enclose them with literal tags: {literal} <script type=text/javscript> function ... </script> {/literal} and for php, use php tags: {php} if(blah==blah) etc etc {/php} like so Link to comment https://forums.phpfreaks.com/topic/165391-getting-option-value/#findComment-874638 Share on other sites More sharing options...
haku Posted July 13, 2009 Share Posted July 13, 2009 Ahh, I thought I had heard something about curly tags, I just didn't know the proper syntax. Not used smarty myself.
