PHP - Session Not Carried Between Sub-folder And Root
Hi all,
I have two PHP files, one in root and the other in a folder called admin. If I set $_SESSION in a file in the admin folder and then view $_SESSION in any other file within the admin folder, everything is OK. However, if I then go to a file in root $_SESSION is blank, and it is blank if I then go back to a file in admin. This problem only exists on my hosting and doesn't happen on a local dev machine. I've compared the php.ini session settings and there both the same. Any ideas? Files admin/test.php <?php session_start(); if( empty($_SESSION) ) { echo "Session not set<br />"; $_SESSION['test'] = "test"; } echo "<pre>";var_dump($_SESSION);echo "</pre>"; /test.php <?php session_start(); echo "<pre>";var_dump($_SESSION);echo "</pre>"; Similar TutorialsHello, I've been hacking at this for about 5 hours, and have been unable to get my session data to pass through to the 3rd page. Here is my code. As you can see I've been trying all types of variation of retrieval. On page 2 I can pull the data from page 1 fine with REQUEST or the longer version.. But for some reason page 3 will not display the first_name and last_name... I'm desperate at this point. I have not been able to find a working answer. I'm running php 5 w/ trans... OFF (default) in .ini.

Sorry if its not clear. Hi guys, I am trying to retrieve some information from sessions. I have this in my header.php <?php if(isset($_SESSION['username'])){ $username = $_SESSION['username']; echo $username; } ?> I am attempting to us glob to display contents of a users folder using a session variable. Example: I have a session variable called department Code: [Select] $row_fullname['department']; In department I have the name of the department the user belongs to such as: office, plant, maintenance, and groundskeeping I created a folder called docs inside of docs there are 4 subfolders called office, plant, maintenance, and groundskeeping I found this code which will display the contents of the folder: Code: [Select] <?php $files = glob( './docs/office/*.*' ); foreach ( $files as $file ) { echo '<a href="./docs/office/' . basename( $file ) . '"target="_blank">' . basename( $file ) . '</a><br />'; } ?> The above code works fine, but I would like it to only display the contents of a departments folder only if the user is part on that department. Here is an example that I know is completely wrong but it may help explain what I am trying to do. Code: [Select] <?php ]<?php $files = glob( './docs/echo $row_fullname['department'];/*.*' ); foreach ( $files as $file ) { echo '<a href="./docs/echo $row_fullname['department'];/' . basename( $file ) . '"target="_blank">' . basename( $file ) . '</a><br />'; } ?>Thanks for your time I got this script: But it give me error, file_get_contents cannot open stream. I need to add the FTP connection with user/pass paramaters. then look in set http url, to get the file contents(images) and transfer to ftp server location. Can Anyone take alook and tell me if I am going down the right path and how to get there. Please Code: [Select] function postToHost($host, $port, $path, $postdata = array(), $filedata = array()) { $data = ""; $boundary = "---------------------".substr(md5(rand(0,32000)),0,10); $fp = fsockopen($host, $port); fputs($fp, "POST $path HTTP/1.0\n"); fputs($fp, "Host: $host\n"); fputs($fp, "Content-type: multipart/form-data; boundary=".$boundary."\n"); // Ab dieser Stelle sammeln wir erstmal alle Daten in einem String // Sammeln der POST Daten foreach($postdata as $key => $val){ $data .= "--$boundary\n"; $data .= "Content-Disposition: form-data; name=\"".$key."\"\n\n".$val."\n"; } // Sammeln der FILE Daten if($filedata) { $data .= "--$boundary\n"; $data .= "Content-Disposition: form-data; name=\"".$filedata['name']."\"; filename=\"".$filedata['name']."\"\n"; $data .= "Content-Type: ".$filedata['type']."\n"; $data .= "Content-Transfer-Encoding: binary\n\n"; $data .= $filedata['data']."\n"; $data .= "--$boundary--\n"; } // Senden aller Informationen fputs($fp, "Content-length: ".strlen($data)."\n\n"); fputs($fp, $data); // Auslesen der Antwort while(!feof($fp)) { $res .= fread($fp, 1); } fclose($fp); return $res; } $postdata = array('var1'=>'today', 'var2'=>'yesterday'); $filedata = array( 'type' => 'image/png', 'data' => file_get_contents('http://xxx/tdr-images/images/mapping/dynamic/deals/spot_map') ); echo '<pre>'.postToHost ("localhost", 80, "/test3.php", $postdata, $filedata).'</pre>'; I want to copy everything in templates/blue to the folder code/ However: shell_exec("cp -r 'templates/blue' 'code'"); Creates a folder called blue inside code. I tried cp -r 'templates/blue/*' 'code', but that didn't do anything. Any ideas?

I have tried to replace the header (Location: 'admin.php') with this: echo "<script>document.location.href='admin.php'</script>"; echo "<script>'Content-type: application/octet-stream'</script>"; I've been trying to read up on solutions but haven't been able to get it sorted. If anyone can offer some advice that would be greatly appreciated as im new to php.

I've been advised to use ob_start("ob_gzhandler"); but I am not sure how to implement this. Any advice is greatly appreciated! Hi guys, I've got a simple script that I'm running from a folder above the root (as a cron job). I've tried the script in the httpdocs folder and it works fine. Code: [Select] mail('email@example.com', 'Before include', '', 'From:<email@example.com>'); // include the myriad class include($_SERVER['DOCUMENT_ROOT'].'/path/to/class'); mail('email@example.com', 'After include', '', 'From:<email@example.com>'); // initiate and instance of our class $obj = new class_name; $email = $obj->email; $file = $obj->file_name; mail('email@example.com', 'End of file', $email.' & '.$file, 'From:<email@example.com>'); If I run this file in httpdocs, it's fine and I get all emails. If I run this from 1 folder above the root (from a cron job), I get the first 2 emails but not the last one, suggesting that the include hasn't worked. Could this be a permissions problem? I have tried running the cron job as both root and apache and changed the owner/group of the script to match. Is there a reason why includes won't work above the root? If I an deep inside of nested folders, how do I get back to the Web Root (as far as directory notation goes)?? Debbie Having problems pointing to where files are. Is this the root?: Code: [Select] include "../connectdb.php"; That file is locate din the root. If I am already in the root when I include that statment, the file isn't found. If I use the above code while I am in the subdirectory hello, (root/hello), it works. I use this in every page, so I think I need a way to point to the absolute root, not relative. I have been getting a lot more client requests to protect files. What is the easiest way to do this. So, basically I have tried doing it outside the public directory. There are too many things that cause issues with this. I haven't been able to get a successfull implementation of this since I started working with this. So I was thinking instead about password protecting a directory that is inside public view, but still get files via PHP. Is there a way to setup a password protected directory, then retreive stuff from that directory using PHP. Or, a good way to put them outside the public folder. Everything I have tried to do to get a file to save outside of public view, has not worked. It always says uploaded but the file is never there. Also, I have verified correct permission for this as well. is there a way in php to link from the root dir ? like in html you just use the '/' at the start for the link " <a herf="/link.php" ></a> " but i noticed this does not work when using php like include or require. so is there anywey to tell a link to start from root dir? without using the ../../link.php Hi All, I googled this and there is endless results. I went through a lot of them but couldn't get this working properly. How do I link from within my web site root to files outside the root? It works for me using relative links i.e. ../../phpfiles/includes but that is going to get messy and I can't get a way of doing absolute links to work. If someone could lay that out so a newbie can get it clearly I would really appreciate it! Also - I understand why I should put all of my php files outside the web root but is this a guaranteed way to secure these files other than someone hacking my ftp access? I've looked at a few site hierarchy examples - Am I right that the only pages within the web site root should be template pages with calls to required files (outside the root), session checks, and content includes and all other includes that have php executable code should be outside the root? I really appreciate the advice and insight. Thank you! Hi, I have a dynamic variable like this: /def/g/qaz/pol/cxz/cba/abc I only wish to keep this: /def/g/qaz/pol/cxz How would I do this? Thanks, - mme hey guys im still having a issue with using the root path when requiring external files. So i can use one path and never have to worry about this issue. require("/functions/function_battle.php"); the file is located here Code: [Select] C:\Software\XAMPP\xampp\htdocs\System_Lords\functions\function_battle.php i dont understand (include_path='.;C:\Software\XAMPP\xampp\php\PEAR') im suppose to be including the php folder or something? Code: [Select] Fatal error: require() [function.require]: Failed opening required '/functions/function_battle.php' (include_path='.;C:\Software\XAMPP\xampp\php\PEAR') in C:\Software\XAMPP\xampp\htdocs\System_Lords\include\battle.php on line 2 Hi, I want to get root path and use on links even if i'm in sub to sub folder etc... suppose my site name is fitness.com and having two subfolder. so url will become http://www.fitness.com/dir/dir_sub here i want to put a link to go to root directory file. there are different ways to do that. e.g: Code: [Select] <a href='../../filename.php'>go to that page</a> but i want to use some constant that always shows to root directory. as i defined here Code: [Select] define("SERVER_NAME" , $_SERVER['HTTP_HOST']); //and used it like this <a href='<?php echo SERVER_NAME; ?>/filename.php'>go to that page</a> it works when we're on root directory. but when we go to sub directory it added sub directory name with it. which i don't want. is there any way? Thanks Because I have include files in a subdirectory called "incl", I cannot rely on using relative paths because that include file is in a header on and the pages are in multiple subdirectories (or in the root). I need some way to get the location of the root (the one where my index file is located). I want to use something like this: $path= $_SERVER['DOCUMENT_ROOT']; include $path."/subdirectory/file.php"; However, when I use $_SERVER['DOCUMENT_ROOT'] I get : /home/content/j/p/f/name55/html/ which is not where the index file sits. Any ideas on how to get the directory where my index file sits? (i.e. the index that gets read when you got to www.domain.com) |
