PHP - Deleting An Obsolete File
Hi fellas, i am wondering if someone can point me in the right direction?
I have a simple upload script where users can upload thier profile picture, but if they want to change that picture i would like to delete the old one, to save space and time cleaning up the left overs. So, without further ado, i gather the info from the existing database: $existingimage = "/profileimage/". $userid2['image']; Then further on in the script when it comes time to add or update the image i have: if (!empty($existingimage)) {unlink($existingimage);} $insert= ("UPDATE userdatabase SET image='$finalname' WHERE user='$userid'"); mysql_query($insert); Only problem is, the unlink part dont work, the original image is still there! Any clues? Similar TutorialsHi, When i launch my code i get the following php error: Warning: unlink(../files/"yCUuH0223e3d6d046acb58678fbb54042e0fe.pdf") [function.unlink]: Invalid argument in C:\xampp\htdocs\intra\VVS\admin\fakture-edit.php on line 74 But in the dir: C:\xampp\htdocs\intra\VVS\files\ The file exists.. here's my php code: Code: [Select] $id = mysql_real_escape_string($_GET['id']); $fil = mysql_real_escape_string($_GET['fil']); $result2 = mysql_query("SELECT * FROM fakture WHERE id=('$id') LIMIT 1"); $row2 = mysql_fetch_array($result2); if ($_GET["op"] == "process") { if (!unlink('../files/"'.$fil.'"')) please just deleting this post I think i figured it out Hey guys, first post and I've just returned to PHP after about 4 years of no coding, so be gentle! In a nutshell I'm creating a photo album and I've pretty much got the majority of it complete, apart from a few tweaks and the obvious ongoing development. I'm at the stage now where I need to moderate images being uploaded, so I've made an admin only script which displays the uploaded images with links that say approve and delete. Uploaded images are stored in uploads/ which are left there until i move them to img/, plus the filename is stored in mysql so I can "<img src='../uploads/".$row['filename']."' width='200'>". Now, I would like to make the Approve button move the image from uploads/ to img/ and I'd like the delete button to remove both the entry from MySQL and the file from the uploads folder and I'm not too sure on how to make it work. Here's what I have so far in the mod.php file (mod for moderation) Code: [Select] $image = mysql_query("SELECT * FROM images WHERE id"); while($row = mysql_fetch_assoc($image)) { echo " <table> <td> <tr> <img src='../uploads/".$row['filename']."' width='200'><br /> </tr> </td> <td> <tr> <a href=''>Approve</a> <a href=''>Delete</a> </tr> </td> </table> "; } You'll have to ignore the table tags, I'm still getting used to positioning items on the screen lol. Any clues would be greatly appreciated Live long and prosper. Dear forum I'm new to this forum and since I'm doing more and more php development, you'll probably going to see me more. For now I got this problem and I hope you guys can help me out =(. I'm building an administartion panel for a website. On this panel the administrator can upload pictures for a gallery. This part works, so normally permissions shouldn't be a problem. The file names are stored in my mysql database for example "pic2.jpg", "pic2.jpg", ... Now I got this form to delete pictures from a specific gallery. It deletes from the database but it just wont delete the files. I'm using a local xampp server. I got the following code: Code: $merk = $_POST["MerkLeegMaken"]; $sql = "SELECT * FROM catalogus WHERE merkId=" . $merk; $resultSet = mysql_query($sql); while ( $row = mysql_fetch_array($query) ) { $url = "../uploads/" . $row["foto"]; // this url is f.e. "../uploads/picture1.jpg", and I'm currently in "/administrationPanel/form.php fclose($url); unlink($url); } $sql = "DELETE FROM catalogus WHERE merkId=" . $merk; mysql_query($sql); $message = "<p class='success'>Het huidig merk is succesvol leeggemaakt.</p>"; (I got in my root dir the directory /uploads and the directory /administartionPanel, so ../uploads should be correct right?" I also tried to delete with "c:/xampp/xampp/htdocs/uploads/pic1.jpg" but that didn't work either. But shouldn't "../uploads/pic1.jpg" work anyway, since I use that same url as the source of an Image below the form. All my different url attempts didn't work. I kept finding the files in my windows explorer =( Hope someone can help. www.phpkode.com I have a bad way with words, so if the title doesnt make much sense nor my post, I apolagize! But I am using a while loop and mysql_fetch_array to echo all information in a table in mysql. With each entry, I have included a button that executes a delete query for that entry. Code: [Select] $delquery="DELETE FROM requests WHERE user = '".$row['user']."'"; mysql_query($delquery,$link2); echo "<font size='19px' color='#009933'>User deleted from request database.When I click the button, the message is echod in every entry listed on the page, and nothing happens. I figured Id use delete from the username, so that way mysql will know which one to delete... but Idk when I think about it thats dumb and makes no sense. Im stuck. This side of the application im trying to make is the admin side where I can process requests. After I process the request I delete it from the database so I know I processed it. I have no idea what query to use for this. Anybody know how I could do this?

I have had my website moved to another server and I can't connect now. If there is a better way? I was given this coding from someone on this website about 4 years ago. I didn't want to use a strait connect because when there was difficulty connecting to the database I received an error giving me and any hacker all the details of the database server. This was to be a more controlled access. Edited by ignace, 09 June 2014 - 01:34 PM. Could anyone tell me why this is not deleting the userip and post id from the database at all.

What am I doing wrong he Code: [Select] mysql_query("DELETE FROM availability WHERE id = '$_POST['id']'"); I am able to echo the id but I must be entering the post item incorrectly into the delete string. Can anyone show me my mistake? Thanks I'm trying to delete the <identifier> node of some XML, using the following code; unsuccessfully.
Can someone help me identify where I'm going wrong? TIA
$newXML = ""; $xmlString = Fedora_API::callGetDatastreamContents($this->pid, 'MODS', true); $doc = DOMDocument::loadXML($xmlString); $xpath = new DOMXPath($doc); $fieldNodeList = $xpath->query("/identifier"); foreach ($fieldNodeList as $node) { $fieldNodeList->removeChild($node); } $newXML = $doc->SaveXML(); I am sorry even i didn't say hello to forum but i need this snippet very urgently. i have Zero knowledge of PHP but unfortunately i need a small code as follow. I'm just trying to get suggestions on what people think would be the best way to go with this. With the bottom part of this card where it s tarts working with the foreach loop its taking what was a UL and for each of each LI's and updating a table with its new data however this way isn't going to work as this is editing a user. Because there could be 5 in the database but the new edit user has only 4 lis so I'm sure you could all see the issue here. What I'm thinking would be best is to have it DELETE the existing characterIDs that have WHERE handler_ID = $handlerID and then just do a new INSERT statement. Anyone else think this would be the best way to go about this? Code: [Select] if (mysqli_num_rows($Qresult) == 0) { $query = "UPDATE `handlers` SET `userName` = '".$userName."', `password`='".$password."', `firstName`='".$firstName."', `lastName`='".$lastName."', `statusID`='".$statusID."', `isAdmin`='".$admin."', `defaultCharID`='".$defaultCharID."', `email`='".$email."' WHERE `ID` = '".$handlerID."'"; mysqli_query($dbc, $query); foreach ($characterIDs as $cID) { $query2 = "UPDATE `handler_characters` SET `handler_id` = '".$handlerID."', `characterID` = '".$cID."'"; mysqli_query($dbc, $query2); } $result = "good"; } Hi, this is the first time I've asked for some help from a forum. I guess this code has sort of got me stumped. So, I have a system where a user can enter a number. The number goes into a mysql database. A random number is also generated and it is added into another column. So, I want users to be able to delete the number using the random number. I've shown it to them, and I need help working my delete script. Code: [Select] <?php $con = mysql_connect("localhost","",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("a8784hos_adopts", $con); $adopt = $_POST['adoptid']; $uniquecode = $_POST['uniquecode']; $result = mysql_query("SELECT uniquecode, id FROM id WHERE id='$adopt'"); mysql_fetch_array($result); if (($adopt == $row['id']) || ($uniquecode == $row['uniquecode'])){ mysql_query("DELETE FROM id WHERE id='$adopt'"); echo 'Done! <br/><br/><a href="tester.php">Go back....</a>'; } else { echo 'Bad unique code. <br/><br/><a href="tester.php">Go back....</a>'; } ?> So, the random number is uniquecode in the database, and the number is id. However, when I try this code, it always tell me I have a bad unique code. What am I doing wrong? Thanks. Hi, I gave the following php script: #!/usr/bin/php -f <?php require_once(dirname(dirname(__FILE__))."/modules/common/common.config.inc.php"); $path = $conf["root"]."/media/images/tricouri/tmp/"; $command = "rm -Rf".$path."*"; if(exec($command)) { echo "Folder cleared\n"; } else { echo "Folder clear failed\n"; } ?> I want to delete some .png files from the ./tmp folder and I receive a rm error: Quote rm: invalid option -- / Try `rm --help' for more information. Folder clear failed The rm -rf command sintax is ok on the linux bash, but from php i receive the error. Php safe mode is off. Can someone help, please ? Does anyone have a code that will automatically delete stuff out of the database after 30 days of being in there...? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=318433.0 I'm trying to write a PHP program that a user will use to register to my site. I have a temporary table temp for which the user's information will be stored until they verify their account using an email that is sent to them. Once they verify their account through email, the information stored in the temporary table will be moved to a table called 'users'. I then want to delete the temporary data that they had stored. Unfortunately I'm having trouble doing this. This snippet of code isn't exactly the entire code, but just a test I've been using since I realized that my real code wasn't working as far as deletion goes. Here is my test code. Code: [Select] <?php include('connect.php'); $sql2="SELECT username FROM temp WHERE username = 'justin'"; $result2=mysql_query($sql2); if($result2) echo ("Record found"."<BR>"); else echo ("Record not found"); $sql3="DELETE FROM temp WHERE username='justin'"; $result3=mysql_query($sql3); if($result3) echo ("SUCESSFUL DELETION"); else echo ("failed"); ?> In this code, I check the temp table to see if 'justin' can be found. This has consistently returned "Record found". On the other hand, my deletion command has not worked yet and will constantly fail. connect.php is correct as far as I know and has worked flawlessly for the other parts of this small project. Is something wrong here? What could be the problem? How would I make a script that would delete any row in a MySQL table that was more than 7 days old? Hii everyone. I'm using the following code to save a file into a folder, and allow files to be deleted from the folder. the upload works fine. The delete does work, but sometimes you have to click on the delete link a few times before the file is deleted. i'm wondering if someone can see where the problem is in the code. Also, when the file is deleted, the history entry is not added. i'm a bit confused why it doesn't. i'd appreciate any assistance which you can provide. thank you.
