PHP - Deleting From Database
Hi.
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 Similar TutorialsDoes anyone have a code that will automatically delete stuff out of the database after 30 days of being in there...? i trying to delete messages out of my message database but im not sure if i'm using this code right or there stuff missing to it :S delete.php <?php require_once('settings.php'); checkLogin('1 2'); $id=$_GET["msgs"]; mysql_query("DELETE messages FROM messages WHERE message_id='$id'"); ?> link usages to delete <a href="delete.php?msgs=<? echo $row['message_id'] ?>">[X]</a> I'm trying to delete rows in the database, based on what checkboxes are left empty by the user... What i have is small application in which a user can add an item to the database and give it tags... for example there is "apple" and it has the tags of "fruit, red, round" What i want is for the user to be able to edit those tags, so the user can remove "fruit" and add "sweet" instead or just remove "fruit" all at the same time. The code i have, somewhat works... This code below loops through the checkboxes and should remove the items that are no longer checked, by going through the database and grabbing all the tags and them checking it against those that are still checked and remove the ones that it didn't find checked...?? However whats happening is when i unchecked say "red" it removes all the other items..so if i had "red, fruit, round' and i want to remove "red" it leaves red but removes the rest. foreach($_POST['tag'] as $r=>$n){ $t = mysql_real_escape_string($_POST['tag'][$r]); $get_tag2 = mysql_query("SELECT * FROM file_cats WHERE fileID='$fileID'") or die(mysql_error()); while($t2 = mysql_fetch_assoc($get_tag2)){ $tmp_tag1 = $t2['category']; if($t==$tmp_tag1){ $remove_tag = mysql_query("DELETE FROM file_cats WHERE fileID='$fileID' AND category='$t' LIMIT 1") or die(mysql_error()); } } } This following piece of code just adds a new tag...however i want it to check to see if that tags already exist in the database, if it does then don't add it just add the new ones.. foreach($_POST['tag'] as $k=>$l){ $tag = mysql_real_escape_string($_POST['tag'][$k]); $add_tag = mysql_query("INSERT into file_cats (fileID, category) VALUES('$fileID', '$tag')") or die(mysql_error()); } My final problem is that i can't remove items if the second snippet of code is there, i have to remove those lines of code in order to remove items, however i can add items with both loops there. I'm basically stuck and hope that someone here can shed some light on what i'm doing wrong, because i know i'm doing something wrong i just can't find it Anyway thank you in advanced I've tried reading through some of the threads but couldnt understand some of them. I've made a newsfeed script which works how i want it to. Now i want to add the function to delete a row from the database from an "admin panel" on the website. So far i have this: <?php include("includes.php"); doConnect(); $get_news = "SELECT id, title, text, DATE_FORMAT(datetime, '%e %b %Y at %T') AS datetime FROM newsfeed ORDER BY datetime DESC"; $result= mysqli_query($mysqli, $get_news) or die(mysqli_error($mysqli)); while ($row = mysqli_fetch_array($result)) { echo '<strong><font size="3">'. $row['title'] .' </font></strong><br/><font size="3">'. $row['text'] .'</font><br/><font size="2">'. $row['datetime'] .'</font><br/><br/><a href="delnews.php?del_id=' .$row['id']. '"> <strong>DELETE</strong></a>';} ?> then my delnews.php is: <?php include("includes.php"); doConnect(); $query = "DELETE FROM newsfeed WHERE id = "$_POST['id']""; $result = mysql_query($query); echo "The data has been deleted."; ?> I believe the problem is $_POST['id']. i've tried different things in there but none work. It displays the echo line but doesnt actually delete anything. I am new to php so this may be a stupid mistake, but try and play nice! Thanks Hi Everyone, Im trying to add a delete button to the message inbox page of my website, where when delete is clicked, the checked messages get deleted from the database. After a bit of research on google i have come up with the code below however i cant get it to work. I have replaced the mysql delete query with echo "checked"; just for debugging. $query = mysql_query("SELECT * FROM users WHERE id='$id'"); $row = mysql_fetch_assoc($query); $submit = $_POST['submit']; $username = $row['username']; $checked = $_POST['message']; $messages_query = mysql_query("SELECT * FROM messages WHERE recipient='$username'"); if (mysql_num_rows($messages_query) > 0) { while ($messages_row = mysql_fetch_array($messages_query)) { if ($messages_row['message_read'] == 0) { echo "<div style='background-color:#FFCCCC;'>"; } $message_id = $messages_row['id']; echo "<a href='message.php?id=$message_id'>"; echo "From: " . $messages_row['sender']; echo "Subject: " . $messages_row['subject'] . "<br />"; echo "</a>"; echo "<form method='POST'><input type='checkbox' name='message[]' value='1' /></form>"; if ($messages_row['message_read'] == 0) { echo "</div>"; } } } else { echo "No messages"; } if ($submit) { if ($checked == "1") { echo "checked"; } } ?> <html> <form method="POST"> <input type="submit" name="submit" value="Delete" /> </form> </html> I have also tried the following but i still cant get it to work: if (isset($checked)) { echo "checked"; } Can anybody see where iv gone wrong? Thanks i am trying to delete files for a user, and then update the database with the new bandwhitch/free space. here is my code: http://pastebin.com/J2XE9Fip i just can't figure out where i'm going wrong... thanks in advance Hello - I'm opening my website up to visitors for free, and trying to bypass a login screen to go straight into the data content that was appearing after a user logged in. I have an index.php file that included the following code at the beginning: <?php session_start(); include("database.php"); include("login.php"); include("/vservers/skyranks/db_connect.php"); ?> <?header("Cache-control: private"); ?> <html> I deleted the "include("login.php"); line, and was successful at bypassing the username and login screen. However, the page that is supposed to display the data content is incomplete. In fact, it only displays my company's logo. Any ideas as to why the data content is not showing up? Thank you for any help with this, as my php is quite novice at this point. Regards - Joe Hi, guys. I am a php newb and stuck (see title). I it will only send the value of 1 tick box over to the page "delete_message.php" This is what i have so far: Code: [Select] <?php // get messages $result = mysql_query("SELECT * FROM tbl_pvt_msg WHERE to_UID='$UID'"); if (!$result) die("Query to show fields from table failed"); while ($data=mysql_fetch_array($result)) { $_SESSION['from_UID']=$data['1']; UIDtoemail(); $from_email=$_SESSION['from_email']; $contents=$data['3']; $timesent=$data['4']; $msg_ID=$data['0']; echo "<form action='scripts/delete_message.php' method='POST' >"; echo "<tr><td>$from_email</td><td>$contents</td><td>$timesent</td><td><input type='checkbox' value='$msg_ID' name='msg_ID' /></td> </tr>"; } // turn uid into email function UIDtoemail(){ $from_UID=$_SESSION['from_UID']; $result = mysql_query("SELECT * FROM tbl_usr WHERE UID='$from_UID'"); if (!$result) die("Query to show fields from table failed"); $data=mysql_fetch_array($result); $_SESSION['from_email']=$data['7']; } ?> </table> <input type="submit" value="Delete" id="delete" /> </form> I'm creating a newsletter and the unsubscribe isn't deleting the database entry like I'm asking it to. Everything else works fine, it even successfully says the user has been removed, but it doesn't actually delete the database entry. I've spent two days trying to figure out why. Here's the code:

This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=334042.0 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? Thanks Could anyone tell me why this is not deleting the userip and post id from the database at all. Thanks Code: [Select] <?php include('dbcon.php'); if($_REQUEST['postId']) { $userip = $_SERVER['REMOTE_ADDR']; mysql_query("update collapsed_likes set likes=likes-1 where post_id= ".$_REQUEST['postId']); mysql_query("delete from collapsed_ip where userip=".$userip." AND post_id = ".$_REQUEST['postId']); $total_likes = mysql_query("SELECT * FROM collapsed_likes where post_id = ".$_REQUEST['postId']." "); $likes = mysql_fetch_array($total_likes); $likes = $likes['likes']; } echo $likes; ?> 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 ? 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. 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'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"; } 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. Hi, 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.'"')) Hi, i have delete link for records and it goes to other page to delete all related records in tables. is there away to get confirmation before the delete process starts?
<?Php
include('session.php');
include('dbcon.php');
if(isset($_GET['Del']))
{
$userid = $_GET['Del'];
$query = "delete from staff where OracleID='".$userid."'";
$result = mysqli_query($con,$query);
if($result)
{
echo "staff deleted";
}
else
{
echo 'check the errors!';
}
$query2 = "delete from attendance_records where OracleID='".$userid."'";
$result2 = mysqli_query($con,$query2);
if($result2)
{
echo "records deleted";
}
else
{
echo 'check the errors!';
}
header("location:viewstaff.php");
}
else
{
header("location:viewstaff.php");
}
?>
how to add confirm message with php before deletion is processed? 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? |
