I am a beginner in php and am working on creating a file hosting website got a form to upload the file from the client in uploadform.php Code: [Select] <html> <body> <form method="post" action="uploadfile.php" enctype="multipart/form-data"> <input type="file" name="usr" id="usr"/><br /> <input type="submit" value="Upload"/> </form> </body> </html> the file handling code is in uploadfile.php Code: [Select] <?php class upload { function fupload() { $dir = "C:\\xampp\htdocs\learning\fileshare database.txt"; echo "My name is: ".$_FILES['usr']['name']."<br/>"; echo "Location ".$_FILES['usr']['tmp_name']."<br/>"; echo "Size:".($_FILES['usr']['size'] / 1024)." kb <br/>"; echo "File type".$_FILES['usr']['type']."<br/>"; if(file_exists("htdocs/".$_FILES['usr']['name'])) { echo $_FILES['usr']['name']."already exists"; } else { copy($_FILES['usr']['name'],$dir); echo "File moved"; } } } $up = new upload(); $up->fupload(); ?> The problem is that it does not copy the file from the tmp directory to the specified one the error i get is: Warning: copy(fileshare databse.txt) [function.copy]: failed to open stream: No such file or directory in C:\xampp\htdocs\learning\uploadfile.php on line 20 I am facing the same problem if i try move_uploaded_file () function Could any one help with this issue, thanks Similar TutorialsThis topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=351056.0 I am trying to write this php code that is a form that allows the user to upload images along with a few other text fields. I keep getting this error when trying to upload the file to the server: Code: [Select] Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phpiPdn6u' to 'http://www.webdesignsbyliz.com/wdbl_wordpress/wp-content/themes/twentyten_2/upload/dd.jpg' in /home/webdes17/public_html/wdbl_wordpress/wp-content/themes/twentyten_2/submit_jewelry.php on line 45 I have the code set up to tell me where the file is supposed to be uploaded, so it appears to upload kind of, but this error message and checking the actual folder on my server proves it doesn't get uploaded to it. I have had a code like this set up before and it worked, I just cannot find my files at the moment. Here is the code: the form: Code: [Select] <form id="jewelry" name="jewelry" method="post" action="http://webdesignsbyliz.com/wdbl_wordpress/wp-content/themes/twentyten_2/submit_jewelry.php" enctype="multipart/form-data"> <table id="jewelry" name="jewelry"> <tr> <td>Cut:</td> <td><input type="text" id="cut" name="cut" /></td> </tr> <tr> <td>Color:</td> <td><input type="text" id="color" name="color" /></td> </tr> <tr> <tr> <td>Carats:</td> <td><input type="text" id="carats" name="carats" /></td> </tr> <tr> <td>Clarity:</td> <td><input type="text" id="clarity" name="clarity" /></td> </tr> <tr> <td>Size Of Ring:</td> <td><input type="text" id="size" name="size" /></td> </tr> <tr> <td>Type Of Gold:</td> <td><input type="text" id="type" name="type" /></td> </tr> <tr> <td>Other Diamonds:</td> <td><input type="text" id="other" name="other" /></td> </tr> <tr> <td>Total Carats:</td> <td><input type="text" id="total" name="total" /></td> </tr> <tr> <td>Certificate Type:</td> <td><input type="text" id="certificate" name="certificate" /></td> </tr> <tr> <td>Appraisal Value:</td> <td><input type="text" id="value" name="value" /></td> </tr> <tr> <td>Upload Image:</td> <td><input type="file" id="file" name="file" /></td> </tr> <td colspan="2"><input type="submit" id="submit" name="submit" value="Submit" /> <input type="reset" id="reset" name="reset" value="Reset" /></td> </tr> </table> </form> the page that inserts it: Code: [Select] <?php $dbhost = 'localhost'; $dbuser = 'user'; $dbpass = 'password'; $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql'); $dbname = 'database'; mysql_select_db($dbname); $cut = $_POST['cut']; $color = $_POST['color']; $carats = $_POST['carats']; $clarity = $_POST['clarity']; $size = $_POST['size']; $type = $_POST['type']; $other = $_POST['other']; $total = $_POST['total']; $certificate = $_POST['certificate']; $value = $_POST['value']; if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000)) { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] .

Also, the filepath is not getting inserted into the table either for some reason, and not sure why. Please, can anyone help? Hi guys, I need a little help. I am running a site in XAMPP whilst I develop it locally. I am trying to upload an image file. Heres my code: $photo=$_POST['photo']; $target_path = "uploads/"; $target_path = $target_path . basename( $_FILES['photo']['name']); if(move_uploaded_file($_FILES['photo']['tmp_name'], $target_path)) { echo "The file has been uploaded"; } else{ echo "There was an error uploading the file, please try again!"; } But I get these errors: Warning: move_uploaded_file(upload/ferriswheel.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/Applications/XAMPP/xamppfiles/temp/phpNwxq6I' to 'upload/ferriswheel.jpg' in /Applications/XAMPP/xamppfiles/htdocs/xampp/whatmycitywears/submitphotoprocess.php on line 53 Am I right in thinking this is some sort of issue with the temp directory? It seems to be putting it somewhere is XAMPSS folders rather then in my directory Any help would be great! Maybe never mind. Just noticed ssphpd doesn't have a group... ps. do I have the umask part right? Edit 2. No, it didn't help... I have two users (ssphpd and apache) which will need to write files to a given directory and its subdirectories. My intent was to set them up with ssphd's group and use the setgid to make all future files and directories inherit that group. Not sure, but I don't think I have this right yet as I indicate at the end of this post. [michael@bb5 ~]$ sudo useradd -r ssphpd [michael@bb5 ~]$ sudo usermod -aG wheel ssphpd [michael@bb5 ~]$ sudo usermod -aG wireshark ssphpd [michael@bb5 ~]$ sudo usermod -aG ssphpd apache [michael@bb5 ~]$ groups apache apache : apache ssphpd [michael@bb5 ~]$ groups ssphpd ssphpd : ssphpd wheel wireshark [michael@bb5 ~]$ [michael@bb5 ~]$ sudo chmod g+rwx -R /var/www/~/storage [michael@bb5 ~]$ sudo chown michael.ssphpd -R /var/www/~/storage [michael@bb5 ~]$ sudo chmod g+s /var/www/~/storage My script to write this files is below:

$this->moveTo($file['tmp_name'], $path);
}
private function getPath(string $name, bool $create):string {
//$name is 20 characters
$p1=$this->uploadDirectory.'/'.substr($name,0,2);
$p2=$p1.'/'.substr($name,2,3);

$old_umask = umask(0);

}
umask($old_umask);
return $p3.'/'.substr($name,9);
}
private function moveTo(string $tmpname, string $path):void {
syslog(LOG_ERR, "attempting to move $tmpname to $path");
$uid = posix_getuid();
syslog(LOG_ERR, "user PHP is running as: $uid - ".posix_getpwuid($uid)['name']);
$gid = posix_getgid();
syslog(LOG_ERR, "group PHP is running as: $gid - ".posix_getpwuid($gid)['name']);
$this->test($tmpname);
$this->test(substr($path,0,-12));
syslog(LOG_ERR, move_uploaded_file($tmpname, $path)?'success':'failure');
}
private function test(string $file):void {
syslog(LOG_ERR, "$file is writable: ".(is_writable($file)?'yes':'no'));
$uid=fileowner($file);
syslog(LOG_ERR, "$file owner: $uid - ".posix_getpwuid($uid)['name']);
$gid=filegroup($file);
syslog(LOG_ERR, "$file group: $gid - ".posix_getpwuid($gid)['name']);
$perms=fileperms($file);
syslog(LOG_ERR, "$file permissions: $perms - ".$this->formatPerms($perms));
}
However, as seen, not only can only apache write files, the newly created directories are displaying apache's group instead of ssphp's group. Any ideas?

So i use the code the code below to display images from a folder into a form. My problem is that i put checkboxes with various selections in order to transfer the selected items later to a file or echo the submission. As it seems at the moment is that i can display correctly everything in my form but for some unknown reason i cannot echo/write to a txt file the files(names) that i choose with the checkbox.There seems to be something wrong with my loop but i'm not sure. I would appreciate any help.thank you in advance.

Thank you very much. Hey Guys,
Been coding PHP for a while but I always wonder about the right way of doing things. I am building an online community which I want to display to members and non-members. With this each screen will have options that are available for members only. I have set up session variables once a user logged in but its getting really old having to nest if statements on ISSET then again to check the values in the variables if it is set. See example below.
Question 1. Is it ok to session_start(); for all site visitors?
Question 2. If Q.1 is ok then is it ok to set all the session variables upfront with blank values as placeholders. This would eliminate the need for ISSET.
if (ISSET($_SESSION['On'])) {
if (in_array($GroupID, $_SESSION['Groups'])) {
$IsMember = 1;
}
else {$IsMember = 0;}
}
else {$IsMember = 0;}
Just wanted to get your thoughts on this.
Thank you,
Jeremy
A form needs to get answers of math quiz, returning numbers, up to 2 digits after the point. In all form examples I noticed the usage of: Code: [Select] ...<input type="text" name="name" /... Cant it be a number? floating or integer? why "text" ? Also, can I limit the form to accept numerical input only or would I need to learn Ajax for that? Once I have the answer, I need to compare it to the correct answer. The method I have in mind is to multiply the answer and the correct one by 100 and compare the integer part. Is there a pre-made function that can do the same? Hi I'm completely new to error handling in PHP and wanted to ask whether I'm doing it right and, if not, what the right way would look like class DBConnection { public function execute($sql) { $query = @pg_query($this->dbconn, $this->prepare($sql)); try { if (!$query) { throw new DBException(); } } catch (DBException $e) { echo "Query execution failed"; exit; } } } Hello there, I'm having a problem displaying money correctly with php. I have a field called "balance" with the type float(10,2), in this field I have a number store as "34.55" which I can go in and look at within phpmyadmin but when I echo this value on the front-end of the site it is displayed as "34.549999237061" Can someone please help? Regards. Whats the best way to handle database errors. I been using ob_start() stuff to run the code and if a database connection error occurs an variable $error turns to 1 and it displays the error code instead of the normal page that should be displayed when no errors occur. It works but I want to know if there is any better way to manage a db connection error while running a script. Also, how do you manage a problem when like 3 queries are ran to setup a new user account and the last one fails because the db connection drops or something, how would you go about handling a 2/3 query successful? I'm really stuck on how to manage errors if a db connection fails after the first connection is successful. I am inserting last names into the database using mysql_real_escape_string(), and outputting the data into a textbox using addslashes(). When I try to display O'Brian "O\" is displayed in the text box. The name is saved corretly as O'Brian in the database. I am printing the string like this: Code: [Select] echo "<input type='text' value='" . addslashes($customer['lName']) . "' blah blah..."; anybody have any ideas? Hi, I have an HTML form created using Dreamweaver and now I need a script to handle the form processing. Basically what I need is for the form data received from the webpage to be organized in an email and then sent to me. I would also like to display a thank you message in the browser so the user knows it was received. I was planning to do this using CGI but a colleague suggested that CGI is old school and nowadays a developer would use PHP for this task. Is PHP the right solution for this project? The examples I have found so far always include the HTML for the form and the script needed to handle it in one file. In my case, I have an HTML form already in place and need it to work with a script to perform the email function. I know I need to set "Action=" on my webpage to point to the PHP script but what would the code look like if no HTML is needed? I hope this makes sense... Thanks for your help! Rob Hi, I'm a beginner in PHP OOP and I'm with some doubts about the correct way of handling errors in PHP. Look at this function for example: public function deleteFileFromDisk($fileNameToBeDeleted) { $handle = unlink($fileNameToBeDeleted); if (!$handle) { $result = "(this->deleteFileFromDisk) - Error, " . $fileNameToBeDeleted . " not deleted."; } else { $result = "(this->deleteFileFromDisk) - Success, " . $fileNameToBeDeleted . " deleted."; } return $result; } Is this the correct way of doing it, or I can do better than this? Let me add some details of what I'm achieving... I'm running class methods, and I need to control errors in the process. If any call to the object throw an error I need to catch, stop all the process and send an e-mail with the error. Here are the object interactions: $testar_classe = new geoIpImportCSV('geolitecity', 'http://geolite.maxmind.com/download/geoip/database/GeoLiteCity_CSV/'); $testar_classe->downloadAndSaveFile('./', $testar_classe->obtainDownloadFileName()); $testar_classe->uncompressZipFile($testar_classe->obtainDownloadFileName(), '.'); $testar_classe->deleteLine(1, 'GeoLiteCity-Location.csv'); $testar_classe->deleteLine(1, 'GeoLiteCity-Blocks.csv'); $testar_classe->deleteDataFromTable('tabela1'); $testar_classe->deleteDataFromTable('tabela2'); $testar_classe->insertLinesToDb('GeoLiteCity-Location.csv', 'tabela1'); $testar_classe->insertLinesToDb('GeoLiteCity-Blocks.csv', 'tabela2'); $testar_classe->deleteFileFromDisk($testar_classe->obtainDownloadFileName()); $testar_classe->deleteFileFromDisk('GeoLiteCity-Blocks.csv'); $testar_classe->deleteFileFromDisk('GeoLiteCity-Location.csv'); Which is the best way of handle this? Create a new method to take care of the exceptions? There are any examples on how to do this? Best Regards. Hello, Am writing a script that involves user input. Take an example: a user fills in a wrong username or password at the page login.php, my login processor (processor.php) detects it, how is the error "WRONG USERNAME OR PASSWORD" supposed to be transferred back to login.php. So far I have been using a session variable to transfer the error but am sure there is a better way to do this without displaying the error on processor.php itself. Thanx in advance I have a prepared statement that returns an Article from my database. It then binds the results-set to variables. Most of the fields in the query are "required", so I *assume* that I am guaranteed to always get values back for those fields... Is that presumptuous? Here is a snippet of my code... // Execute query. mysqli_stmt_execute($stmt); // Store results. mysqli_stmt_store_result($stmt); // Check # of Records Returned. if (mysqli_stmt_num_rows($stmt)==1){ // Article was Found. $articleExists = TRUE; // Bind result-set to variables. mysqli_stmt_bind_result($stmt, $articleID, $title, $description, $keywords, $heading, $subHeading, $publishedOn, $author, $body, $referenceListing, $endnoteListing); // Fetch record. mysqli_stmt_fetch($stmt); // Close prepared statement. mysqli_stmt_close($stmt); // ???? Is it sufficient to have code like this... Code: [Select] <title><?php echo $title; ?></title> ...or do I need more error-handling?? Hope that makes sense?! Thanks, Debbie I'm trying to develop a website file manager. I want to allow SSI, and would like to handle it specifically.. Code: [Select] $regexp = "<!--#include\s[^>]*virtual=(\"??)([^\" >]*?)\\1[^>]*\/-->"; if(preg_match_all("/$regexp/siU", $body, $matches, PREG_SET_ORDER)) { foreach($matches as $match) { $includeFile = $match[2]; } } This snippet shows how you would get the included file path in the SSI code of the website body [ the $body tag ], but I don't need to just find it- I want to replace the SSI code with a simpler code in the HTML that appears in the editor for easy management.. Then switch back from my easier code to the actual SSI code.. Example: Replace Code: [Select] <!--#include virtual="/newsManager/output.php"--> With Code: [Select] {INCLUDE=/newsManager/output.php} THEN when the user saves the page, Replace Code: [Select] {INCLUDE=/newsManager/output.php} With Code: [Select] <!--#include virtual="/newsManager/output.php"--> Is there an easy fix or should I just switch to a full blown template engine.. even though this is the only required feature? I have set an SQL field as unique so that duplicates can't be entered, however rather then having the page error out and show the Error: Duplicate entry 'entry' for key 'field' I would like to be able to have a little div appear and say something like "this entry already exists" I already have it set to show that the item has been added but I have no idea were to start to make this work. Any ideas? Thanks, Jim Hi ..am new to PHP and am using it to solve some mathematical problems which require extensive computation. Following is a code to solve a problem: Code: [Select] <?php $num =1; $n =0; $temp = 0; $count =0; $Final =0; While( $num < [color=orange]1000000)[/color] { $n = $num; while($n >1) { if(( $n % 2) == 0) { $n = $n/2; $temp++; } else { $n =3*$n +1; $temp++; } } If($temp > $count) { $count =$temp; $Final =$num; } $num++; $temp =0; } echo $Final; echo "<BR>"; echo $count; ?> I am running into "Maximum execution time of 30 seconds exceeded" error...its happening coz of the number 1 million...the code wrks fine for 100,1000,10000 and 100000...but breaks down @ 1000000.....is there any way to solve this situation...or PHP is not capable of handling huge numbers? please help...am stuck with this even though am so close to solving the prob. Thanks Abhijeet This doesn't work. Based off what I have seen online, it is suppose to. Basically, this is what I tried, and the quote is what was returned. I have no idea how to get this to work. It should have been pretty standard based off of the PHP documentation. The Xpath idea I got from someone else. Either way if I try to use find element by id or tag name it still returns an empty array, no matter what. Any advice on what I am doing wrong is appreciated. It doesn't matter what URL I try, none of them seem to work. Code: [Select] <?php $school_data = file_get_contents('http://www.infotechnologist.biz'); $doc = new DOMDocument(); $doc->validateOnParse = true; $doc->loadHTML($school_data); $xpath = new DOMXPath($doc); $tags = $xpath->query('div'); echo '<pre>'; print_r($tags); echo '</pre>'; ?> Quote DOMNodeList Object ( ) want something like: Code: [Select] date('F j, Y, g:i a') but in central timezone, how do I change the timezone to central? |
