{
if(!$this->DBLogin())
{
$this->HandleError("Erro na ligação à Base de Dados!");
return false;
}
$image =
$iduser = $this->UserId();
$nresult = mysql_query("SELECT t1.idatividade, t1.atividade, t1.data, t1.hora, t1.local,t2.nome FROM atividades t1, utilizador t2 WHERE t2.idutilizador = '$iduser'", $this->connection) or die(mysql_error());
$num_rows = mysql_num_rows($nresult);
echo "<table>";
echo "<tr>
<td>Nome</td>
<td>Data</td>
<td>Hora</td>
<td>Local</td>
<td>Intervenientes</td>
<td>Operações</td>
</tr>";
while($row = mysql_fetch_assoc($nresult)) {
echo "<tr>";
$id = $row['idatividade'];
echo "<td>".$row['atividade']."</td>";
echo "<td>".$row['data']."</td>";
echo "<td>".$row['hora']."</td>";
echo "<td>".$row['local']."</td>";
echo "<td>".$row['nome']."</td>";
echo "<td>".'<a href="editaAtividade.php?id=',$id,'"><img src="images/tick.png"></a>'.' / '.'<a href="' . $this->removerAtividade($id) . '";><img src="images/delete.png"></a>'."</td>";

I wish to find out is there any possible that I can delete some data inside my php website but inside my sql database, the record will still at there?
Thank you.
I'm trying to set it so that it will delete an entire populated directory based upon a value in the database then after finishing that to go back and delete that row in the database. my current code is Code: [Select] <?php $page_title = "Central Valley LLC | Photo Addition" ?> <?php include("header.php"); ?> <?php include("nav.html"); ?> <div id="content"> <form action="delprod.php" method="post" enctype="multipart/form-data"> <label for="which">Choose A Product To Remove:</label> <?php $con = mysql_connect("localhost","phoenixi_cv","centraladmin"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("phoenixi_cvproducts", $con); $result = mysql_query("SELECT * FROM Products"); echo "<select name=\"which\">"; while($row = mysql_fetch_array($result)) { echo "<option "; echo "value=\"" . $row['id'] . "\">"; echo $row['Name'] . "</option>"; } echo "</select>"; mysql_close($con); ?> <br /> <input type="submit" name="submit" value="Submit" /> </form> </div><!--#content--> <?php include("footer.html") ?> and the delete script Code: [Select] <?php $con = mysql_connect("localhost","phoenixi_cv","centraladmin"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("phoenixi_cvproducts", $con); $result = mysql_query("SELECT id FROM Products WHERE id=$_POST['which']"); $row = mysql_fetch_array($result) chdir('assets'); chdir('images'); $mydir = $row . '/'; $d = dir($mydir); while($entry = $d->read()) { if($entry!="." && $entry!="..") { unlink($_POST['which'] . '/' . $entry); } } rmdir($mydir); $result = mysql_query("DELETE * FROM Producs WHERE id=$_POST['which']"); ?> Thank you in advance for all your help. any easier ways of approaching this will be welcome as well I am querying... $sql = "SELECT `messages_inbox`.`message_id`, `users`.`firstname`, `users`.`lastname`, `users`.`username` AS `from`, '${user_info['username']}' AS `to`, `subject`, LENGTH(`files`) AS `len`, 'inbox' AS `box`, DATE_FORMAT(`messages_inbox`.`time` ,'%T %D-%M-%Y') AS `time` "; $sql .= "FROM `messages_inbox` INNER JOIN `users` ON `messages_inbox`.`from_id` = `users`.`id` WHERE `to_id` = ${user_info['uid']} AND `messages_inbox`.`deleted` = 0 ORDER BY `messages_inbox`.`message_id` DESC"; and I am trying to output $displayName = ucwords("${message['firstname']} ${message['lastname']}"); by using $messages = pm_fetch_all($_GET['box']); I know my fetch works but for some reason firstname and lastname are only returning the logged in users first name and last name, not the person who sent the message. Hi, I need a simple command to delete all rows where userID = 2567 I had a shot but didn't work: DELETE FROM * WHERE userID='2567' || usgID='2567' My website is spammed by this user so I want to delete all records by this userID in my database. Hope someone can help and thanks! I need a bit of help. I am displaying records from a db, and want the user to be able to delete a record. I'm almost there (I think) but it doesn't pass the variable ($hours_id) to the delete query. Any ideas? Should be easy...but I'm just at my end. <?php include '../php/config_conn.php'; $querysum = "SELECT SUM(total_time) FROM `coop_hours` where user = '".$_SESSION['user_name']."'"; $resultsum = mysql_query($querysum); $arr = mysql_fetch_row($resultsum); $resulthours = $arr[0]; $querytime = "SELECT * FROM `coop_hours` WHERE user = '".$_SESSION['user_name']."'

Given my primary key is mID and a column in the table is Title, here is the code I'm working with: $sql="delete from myDb.Titles where mID=" . $_GET['mID']; if (mysql_query($sql)) { $target="delete.php?"; } echo "Successfully deleted title: " . $_GET['Title']; The actual delete itself is working fine and the record deletes properly. What I am trying to do is display the Title field associated with the record being deleted and it's not working. I don't know if I am misusing the GET function or not, but that's where I am. Any help would be appreciated. ok, so how would I insert a link to remove a photo from this code: Code: [Select] <?php include("connect_to_mysql_1.php"); $query = "SELECT link, id FROM products where page123=$page ORDER BY listorder ASC "; $result = mysql_query($query); while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $link = stripslashes($row['link']); $id = stripslashes($row['id']); ?> <li id="arrayorder_<?php echo $id ?>"> <img src="<?php echo $link; ?>" width="300" height="250"/> <div class="clear"></div> </li> <?php } ?> </ul> the images are able to move around but I need to know a way to keep photos with their own delete link. I am thinking of someway using listorder and the page123 to do it. could anybody help. I can't really think of a good way to describe the issue... I get registered spammers on my website, they seem to bypass captcha (manually spamming I believe) and we all know why IP ban is no good so I want to be able to simply delete all rows on my database where this user comes from. Can you use one query to delete from all tables with WHERE userID= '$userID' ?? hi. just a quick question about a delete link i have on a page ive made. basically with the code i have currently...nothing at all happens when i click delete...and i cant for the life of me see the problem. here is the code for the page where the delete link is. $sql=mysql_query("SELECT items.itemname, cat.catid, cat.category FROM items,cat WHERE cat.catid=items.catid"); $temp_item = ""; while($res=mysql_fetch_array($sql)) { echo "<table cellpadding='0' cellspacing='0' width='700'><tr>"; if($res['category'] != $temp_cat ) { echo "<td width='30%'>" . "<b>" . $res['category'] . "</b>" . "</td>" . "<td width='30%'><a href='delcat.php?id=$res[catid]'>Delete Category</a></td></tr>"; $temp_cat=$res['category']; } and here is the code for the delete page that should do the deleting. include_once("config_class.php"); $db = new db(); // open up the database object $db->connect(); // connect to the database //getting id of the data from url $id = $_GET['id']; //deleting the row from table $result=mysql_query("DELETE FROM cat WHERE listid=$id"); //redirecting to the display page (index.php in our case) header("Location:list.php?id=$id"); as i said nothing happens...please help anybody?

Hello everyone, I am attempting to delete a row from my SQL database. I'm using phpMyAdmin for my database manager. I've tried to do this two different ways (which are posted below), but each way is initiated by selecting a delete button on the previous page. I'm not getting any errors, and it is running through and displaying the "Success!" line, but not deleting anything. Thanks in advance for any help. Attempt #1: $max = mysql_query("SELECT MAX(ART_ID) AS maxAID FROM Artisan"); $numrows = mysql_num_rows($max); if($numrows == 0) { echo "Artisan was not deleted."; ?> ---some html filler that doesn't use the php above or below---- <?php } else { while (mysql_fetch_array($max)) { $ART_ID = $row['maxAID']; $deleteArtisan = mysql_query ("DELETE FROM Artisan WHERE ART_ID = '$ART_ID'"); $deleteAnswers = mysql_query ("DELETE FROM ArtisanAnswer WHERE ART_ID = '$ART_ID'"); echo "success!"; if (!$deleteArtisan || !$deleteAnswers) { die ("error: " .mysql_error()); } } } Attempt #2: $id = $_REQUEST['ART_ID']; $max = mysql_query("SELECT * FROM Artisan WHERE ART_ID = '$id'"); while(mysql_fetch_row($max)) { $deleteArtisan = mysql_query ("DELETE FROM Artisan WHERE ART_ID = '$ART_ID'"); $deleteAnswers = mysql_query ("DELETE FROM ArtisanAnswer WHERE ART_ID = '$ART_ID'"); echo "success!"; if (!$deleteArtisan || !$deleteAnswers) { die ("error: " .mysql_error()); } } |
