PHP - Deleting File

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;
?>

Does anyone have a code that will automatically delete stuff out of the database after 30 days of being in there...?

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.

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 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'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,

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 use this this same exact delete for users to delete their own account with no problem
for some reason this code below is deleting all my rows in each table


Code: [Select]
<?php 
if(isset($_POST['delete'])) {
                                                                      // this is a check box you need to check in order to confirm
  if(empty($_POST['confirm'])){ 
 
  echo "You need to check confirm";

}else{

mysql_query("DELETE FROM `users` WHERE `goauld`= ".(int)($_POST['delete_goauld']));
mysql_query("DELETE FROM `game` WHERE `goauld`= ".(int)($_POST['delete_goauld']));

echo "$delete_goauld was deleted<br />\n";
}
}
?>

Ok I am trying to delete some rows from a database. I have done this before with success so I thought I could use the same method just modify it a little and it would work. Man was I wrong. Any help on this is much appreciated below is my code.

Code for the Query to get the data from the database and for displaying the results in a table:
Code: [Select]

//GET DATA
$sql = "SELECT * FROM `".$tblname."` ORDER BY $orderby $sort LIMIT $startrow,$limit";
$result = mysql_query($sql) or die(mysql_error());
$result2 = mysql_query($sql);

//START TABLE AND TABLE HEADER
echo "<form name='form1' method='post' action=''><table style='font-size:9.5px;'>\n<tr><th>Delete</th>";
$array = mysql_fetch_assoc($result);
foreach ($array as $key=>$value) {
if($config['nicefields']){
$field = str_replace("_"," ",$key);
$field = ucwords($field);
}

$field = columnSortArrows($key,$field,$orderby,$sort);
echo "<th>" . $field . "</th>\n";
}
echo "</tr>\n";

//reset result pointer
mysql_data_seek($result,0);

//start first row style
$tr_class = "class='odd'";

//LOOP TABLE ROWS
while($row = mysql_fetch_assoc($result)){


echo "<tr ".$tr_class.">\n<td><a
 href='remove_rec.php?id=". $rows['ID'] . "'><p>Delete</p></a>";
echo "</td>";
foreach ($row as $field=>$value) {
echo "<td>" . $value . "</td>\n";
}
echo "</tr>\n";
//switch row style
if($tr_class == "class='odd'"){
$tr_class = "class='even'";
}else{
$tr_class = "class='odd'";
}

}

//END TABLE
echo "</table>\n</form>";

Here is the code that should delete the row:
Code: [Select]
$tblname = 'tablename';
// get value of id that sent from address bar
$id=$_GET['ID'];

// Delete data in mysql from row that has this id
$sql="DELETE FROM $tblname WHERE ID='$id'";
$result=mysql_query($sql);

// if successfully deleted
if($result){
echo "Deleted Successfully";
echo "<BR>";
echo "<a href='leads3.php'>Back to Results</a>";
}

else {
echo "ERROR";
}

When I click on the link to delete a record it redirects me to the appropriate page with the "Deleted Successfully" message but when I go to view the results the row was not deleted. Any help on this would, again, be greatly appreciated.
