acornrevolution Posted May 24, 2007 Share Posted May 24, 2007 Hi. I'm trying to do a few different things on different pages with PHP and wondering if I could get some help. First, I'm using a php include script in which all other consecutive pages load into the first index page (index.php?page=x). At the top is a small flash presentation. When a link is clicked, the correct page is loaded, and the movie starts over, because basically it is being loaded again. Is there any way around this? Second, I am trying to make a simple login page. On the front page, I would like to be able to allow a user to enter their username, which then would direct them to their folder (username = hello, folder is users/hello) and on that page, I will use a php password script I have. How can I do this? Thanks for any help!!!!! (A)corn Quote Link to comment https://forums.phpfreaks.com/topic/52736-solved-a-few-php-questions/ Share on other sites More sharing options...
john010117 Posted May 24, 2007 Share Posted May 24, 2007 For your first question... I don't really recommend it, but use iframes. For your second question... header('Location: users/ ' . $username); Quote Link to comment https://forums.phpfreaks.com/topic/52736-solved-a-few-php-questions/#findComment-260409 Share on other sites More sharing options...
acornrevolution Posted May 24, 2007 Author Share Posted May 24, 2007 Thanks for the quick reply. I tried using Iframes but it kept throwing off my layout and creating an empty white space under all my work. I have a side bar of about 200px, a header of 250, and a menu under that of 20. Under that is the main content. I size the iframes for 100% (100% of the remaining space right?) but it throws everything off and with different browsers, creates 2 slidebars on the right - which is ugly. If you have a better suggestion on how to fix it, I would love to hear it! Where do I insert the header tag exactly? How does it work?

john010117 Posted May 24, 2007 Share Posted May 24, 2007 I'm not very experienced with iframes, so I can't say exactly. I'll let the other users answer that. For your second question, I'm assuming you have one page that displays the form, and another page which processes the form. If my assumption is correct, put that code near the top on the processing page. So it'll look something like this: form: <form action="process.php" method="POST"> <input name="username" type="text"> </form> processing page: <?php $username = $_POST['username']; // If the form wasn't submitted, redirect the user to the form page if(!isset($username)) { header('Location: form.php'); exit(); } else { header('Location: /' . $username . '/'); } ?> Note that I haven't tested this yet. But the layout of the code should look similar to this.

acornrevolution Posted May 24, 2007 Author Share Posted May 24, 2007 Hopefully I don't make this sound stupid. The form will just have a username box. Say the username is xj. Submitting the form will bring the user to /users/xj. That page will prompt for password. On process.php, what is form.php pointing too? Is that the form, and it redirects back if the username is incorrect?

john010117 Posted May 24, 2007 Share Posted May 24, 2007 The form I've posted is the main one (where the user types in their username to be redirected to your password script.

alecks Posted May 24, 2007 Share Posted May 24, 2007 Ha! This is so weird! I was just working on something like this. I ended up using AJAX. in the <head> of your website, add <script language="javascript"> http = getHTTPObject(); function getHTTPObject(){ var xmlhttp; /*@cc_on @if (@_jscript_version >= 5) try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); }catch(e){ try{ xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); }catch(E){ xmlhttp = false; } } @else xmlhttp = false; @end @*/ if(!xmlhttp && typeof XMLHttpRequest != 'undefined'){ try { xmlhttp = new XMLHttpRequest(); }catch(e){ xmlhttp = false; } } return xmlhttp; } function loadPage(page){ var url = page + ".php"; http.open("GET", url, true); http.onreadystatechange = handleHttpResponse; http.send(null); } function handleHttpResponse(){ if(http.readyState == 4){ document.getElementById('content').innerHTML = http.responseText; } } </script> That's basically all AJAX has to it. It's really not as hard as it sounds Now, create a PHP script that outputs the content of what you want each page to have in plain text. Change "var url" under "function loadPage" in the script above to the location of this PHP script. (So, if, for example, the content is fetched from a sql database, have a php script that does that in a different file.) Also, change this document.getElementById('content').innerHTML = http.responseText; in the handleHttpResponse function to whatever <div> that you want the page to load in. Now, on your site, have the navigation links look like this: <a href="javascript:loadPage('THE PAGE YOU WANT TO LOAD MINUS THE .PHP')">The Link</a> That should work Example files: <?php // Script.php echo "This is the content of the page that I want to load asynchronously so that I don't have to reload the flash header everytime."; ?> The website index. (index.html) <html> <head> <title>This is a simple page</title> <script language="javascript"> http = getHTTPObject(); function getHTTPObject(){ var xmlhttp; /*@cc_on @if (@_jscript_version >= 5) try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); }catch(e){ try{ xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); }catch(E){ xmlhttp = false; } } @else xmlhttp = false; @end @*/ if(!xmlhttp && typeof XMLHttpRequest != 'undefined'){ try { xmlhttp = new XMLHttpRequest(); }catch(e){ xmlhttp = false; } } return xmlhttp; } function loadPage(page){ var url = page + ".php"; http.open("GET", url, true); http.onreadystatechange = handleHttpResponse; http.send(null); } function handleHttpResponse(){ if(http.readyState == 4){ document.getElementById('content').innerHTML = http.responseText; } } </script> </head> <body> <h1>This is my website</h1> <div id="flash_header" style="width:500px;height:100px;padding:10px;margin:10px;">Pretend flash header.</div> <div id="navigation"><a href="javascript:loadPage('script')">This is a link to the page I want to load asynchronously</a> into the div CONTENT.</div> <div id="content">The content output by script.php will be put here.</div> </body> </html> You get the idea. With a little imagination and better programming you can get some pretty good results. You can do alot more stuff than what you can do with iframes. (plus, it's compliant unlike iframes).

acornrevolution Posted May 24, 2007 Author Share Posted May 24, 2007 I'll try that out and see how it works, let you know in a few days!!! Quote Link to comment https://forums.phpfreaks.com/topic/52736-solved-a-few-php-questions/#findComment-260464 Share on other sites More sharing options...
acornrevolution Posted May 29, 2007 Author Share Posted May 29, 2007 Thanks, both codes worked, but leave me with a few questions: john010117: The the user types in a username (which is essentially typing in a diretory) that doesn't exist, how can I have the form recognize this and redirect the user to a different page. alecks: The AJAX code worked great and was exactly what I was looking for! Is it cross broser-compatible, and what exactly is: /*@cc_on @if (@_jscript_version >= 5) try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); }catch(e){ try{ xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); }catch(E){ xmlhttp = false; } } @else xmlhttp = false; @end @*/ ??
