Thank you.
Hi there, I currently have this code that is supposed to delete a message according to their id. The ID is sent through a hidden input field, but it's still somehow not parsing correctly. Here it is.... Code: [Select] $query = mysql_query("SELECT * FROM messages WHERE to_user='$username' ORDER BY message_id DESC") or trigger_error('Error: '.mysql_error()); $numrows = mysql_num_rows($query); if ($numrows > 0){ while ($row = mysql_fetch_assoc($query)){ $id = $row['message_id']; $from = $row['from_user']; $to = $row['to_user']; $title = $row['message_title']; $content = nl2br($row['message_contents']); $date = $row['date']; $read = $row['message_read']; echo" <center> <table border='0' width='100%' style='text-align:center;'> <tr>"; if($read == 0){ echo"<td width='25%'><font color='white'><a href='inbox.php?action=view&mid=$id'><b>$title</b></a><b><i>NEW!</i></b></font></td>"; } else{ echo"<td width='25%'><font color='black'><a href='inbox.php?action=view&mid=$id'>$title</a></font></td>"; } echo"<td width='25%'><font color='black'>$from</font></td> <td width='25%'><font color='black'>$date</font></td> <td width='25%'><font color='black'> <form action='inbox.php' method='post'> <input type='submit' name='delete' value='Delete' class='button'> <input type='hidden' name='id' value='$id'> </form></td> </tr> </table></center> <br>"; if(isset($_POST['delete'])){ $message_id = $_POST['id']; mysql_query("DELETE * FROM messages WHERE message_id='$message_id'"); echo"<script type='text/javascript'> alert('Message deleted!') </script>"; } } } I have made a simple form where users who have been subscribed and unsubscribe by inserting their email address. In my database using PHPMyAdmin, my database to store the emails is 'Links', the table is 'email' and the fields are the 'id' and 'emailaddress'. What I have tried is making a text input field, where the user ill insert his or her email address, to unsubscribe on the website. As a result the user's field for his or her email address will be delete in the database which is saving the emails for all users who have subscribed. My HTML codes a Code: [Select] <p>Subscribe for newsletters:</p> <img src="images/k-newsletter-icon.png" width="96" height="96" alt="subscri"/> <form action="index.php" method="post"> <input type="text" size="25" placeholder="Your email address..." name="enter"/> <input class="submit" type="submit" value="Subscribe" name="subscribe"/> </form> My PHP codes a Code: [Select] <?php if ($_SERVER['REQUEST_METHOD'] == 'POST') { $email = $_POST['enter']; @mysql_connect ('localhost', 'root', '') or die ('Error'); @mysql_select_db ('links') or die ('Error'); if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { echo "Not an email"; return false; } else { mysql_query("DELETE FROM email WHERE emailaddress ='$email'"); echo "deleted"; } } ?> When I test it,it is not working, as I see the email which was saved, is still in the database! Help! Hello there, I have this bit of code: Code: [Select] <?php $host="localhost"; // Host name $un="**"; // Mysql username $password="**"; // Mysql password $db_name="**"; // Database name $tbl_name="weddingpics"; // Table name // Connect to server and select database. mysql_connect("$host", "$un", "$password")or die("cannot connect"); $id = intval($_POST['id']); $sql="DELETE id='$id' FROM $tbl_name WHERE id=$id"; $result=mysql_query($sql); if($result){ echo "Successful"; echo "<BR>"; echo "<a href='weddingcakes.php'>View result</a>"; } else { echo "Error"; } ?> I've tried to reword the delete query but still no avail. If you are wondering where it pulls the `id` variable, it is on the previous page as a hidden attribute. The code is posted he http://codepad.org/Fck5s2zz The attached file (delete_user.php) is the same as the code in the link above. The same code is also posted below. [text] What I am trying to do is create a function that will allow me to delete a user from my mysql database. I have an HTML select that outputs the username(s) using the function get_admin_username() (The function is posted below) There is also a HTML form I am using to make this happen. (Also posted below) In other words I would select the user I would like to delete, and click submit which will then delete the user from the database. The problem I am having is I do not know how to pass values from the HTML select, or the form, or even use the submit button value. I am not sure If I need to create a function to achieve this. Basically I don't know what to do this at all for that matter. I thought I might have gotten close but I thought wrong, and failed. I was told (in the php irc) that my method was way off and wrong but was given no help after that. I do have an example to show you of how I tried to accomplish this, but being told that I was wrong I did not feel that it was even worth posting it. I am lost and have been at this for two days now. I am a noobe but I do understand allot (I think). Someone, anyone, please help.

[/code] tags added. basically could somebody help me with information on having a php script that deletes mysql rows which are older than 3 hours old. I know MYSQL table will need a date/time column but how can I only target ones which are 3 hours old+. Thanks I have a table with several fields, one of which is an amount of days after which the row will be deleted. Every time the script is run, I want to check for old entries and delete them. How would I do this? I am trying to delete child nodes using the parent_id, id. like the following...
id | parent_id
1 | 0
2 | 1
3 | 2
deleting id 2 should also delete id 3. How to get the follow code to work?
i am using mysql 5.1. this code gives a query syntax error on line number... but no error message.
"CREATE TABLE test( `id` INT(20) NOT NULL AUTO_INCREMENT, `parent_id` INT(8) NOT NULL, `title` TEXT NOT NULL, FOREIGN KEY (parent_id) REFERENCES test (id) ON DELETE CASCADE, PRIMARY KEY (`id`) ) ENGINE=INNODB DEFAULT CHARSET=utf8 ";when i use the following code, there is no errors. "CREATE TABLE test( `id` INT(20) NOT NULL AUTO_INCREMENT, `parent_id` INT(8) NOT NULL, `title` TEXT NOT NULL, PRIMARY KEY (`id`) ) ENGINE=myisam DEFAULT CHARSET=utf8 ";notice in the above code that i have changed the word INNODB to MYISAM for the ENGINE and removed the FOREIGN KEY. this code works but no "on delete cascade". Hi all, I am currently learning PHP and have the homework to produce a function that can delete a row in a MySQL database table by clicking on an item in a drop-down menu in a web page. The code I have produced up until now is this:
<!DOCTYPE HTML>
<html lang="de">
<head>
<meta charset="utf-8" />
<title>E3_Artikel_Löschen</title>
</head>
<body>
<form method = "GET">
<?php
$anr="";
try {
$pdo = new PDO ('mysql:dbname=bestelldatenbank;host=localhost;charset=utf8', 'root', '');
} catch (PDOException $error){
die ($error->getMessage());
}
?>
<div>
<p>
<label for="artikel">Artikel: </label>
<select id="artikel" name="artikel">
<?php
$sqlSelect = "SELECT anr, name FROM artikel ORDER BY anr ASC";
foreach ($pdo->query($sqlSelect) as $row) {
echo "<option value=$row[0]>$row[0] | $row[1]</option>\n";
$anr = $row[0];
}
?>
</select>
<input type = "submit" value = "Delete row" />
</p>
</div>
<?php
function artLoeschen($anr) {
echo "Function called $anr";
if(isset($_GET[$anr])) {
$anr = $_GET[$anr];
$sqlDelete = $pdo->query("DELETE FROM artikel WHERE anr = :anr");
if ($stmt = $pdo->prepare($sqlDelete)) {
$stmt->bindParam(':anr', $anr);
$stmt->execute();
}
echo "<h2><b>Artikel gelöscht!</b></h2>";
}
}
?>
</form>
</body>
</html>
So, I have observed the following when I run the script in a browser: 1. The HTML works as expected and I get a drop-down list with the article number and description of each item in the affected table. 2. I can click on an item in the list and it populates the top item in the drop-down list. 3. When I click delete row, the selected item is not deleted. 4. There are no error messages returned but the function is not executed (at least not as I would like to expect).
I have obviously missed something or made a mistake in my code. I would be very grateful for any help...this is driving me mad! :) Regards, Kevin Hi, I'm new to the forum so this could go in the MySQL section but I'm not sure. I am trying to make a page that will list all records from a column in HTML table and have a delete button to remove a specific record. I have got to the part where I have listed the records in a table. Note: Only records from a specific column ('links') are printed. Here is the code: Code: [Select] $con = mysql_connect("localhost","***","***"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("***", $con); $result = mysql_query("SELECT * FROM main"); echo "<table border='1'> <tr> <th>Current links</th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['links'] . "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); How would I go about adding a delete button next to each record to delete that specific record? Thanks for any help. Hello,
First of all I'd like to say thank you for all the great information on the forums, I've been reading a lot on here lately.
I've started to make a website where users can log in and submit items to a database, which is then displayed on another page.
If Tom and Bill both post 10 items, all 20 items will be displayed on the "listings" page, however on the main log in screen Tom will only see his own 10 items and Bill will see his own 10 items.
This is all working perfectly, however, I now need to add a delete button so that they can delete specific items.
I have loosely followed this tutorial here to get the table to display as I want it (amongst a few other things, such as the user logins) http://www.wickham43...mphptomysql.php
I've added the delete button in the PHP loop for each row, I just can't figure out how to delete the specific row when clicked.
Any help would be really appreciated
Edited by eklem, 22 October 2014 - 08:10 AM. I have a form that submits a record and saves it to the database, I've got that working already, I'm trying to figure out if there is a cleaner way to delete a record with a button that gets a value from the unique key, in this case 'id' here is how the delete button looks like: // get info from table $query = "SELECT id, Title, Message FROM table_name"; $result = mysql_query($query); //displaying all data while($row = mysql_fetch_assoc($result)) { echo" <div class='status'><h3>{$row['Title']} <br></h3>" . " <h5>{$row['Message']} <br><br></h5>"; $id = $row['id']; //trying to get unique key from database //delete button echo "</div> <form action='delete.php' method='post' /> <input type='hidden' name='delete' value='yes' /> <input type='hidden' name='id' value='$id' /> <input type='submit' value='remove' /></form>"; } As you can see, i'm trying to give $id a unique value but for some reason i'm not getting it. The delete.php code looks like this: if (isset($_POST['delete']))// check if delete was clicked { $query = "DELETE FROM table_name WHERE id='$id'"; echo "$id Deleted successfully"; } elseif(!mysql_query($query, $db_server)) { echo "DELETE failed: $query<br />" . myql_error() . "<br /><br />"; } mysql_close(); I'm new to php and still learning so, if you think there are other ways to do this, please let me know, the button won't do anything to the data. Thanks in advance i have a table of say 100 entries. i want to delete all but the 10 newest of those rows with a prepared statement. im fairly new with prepared statements so the syntax with a subquery is throwing me a bit.
$stmt = $db_connect->prepare('DELETE FROM table WHERE owner=? AND owner NOT IN (SELECT owner FROM table ORDER BY dob DESC LIMIT 10)');
$stmt->bind_param('i', 0);
$stmt->execute();
$stmt->close();
Hello everyone I need code for this question
would you help me please..?
Ok this is puzzleing. I am geting "Could not delete data: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1". but its is deleting the entry that needs to be removed. The "1" is the entry. Just not sure what is causing the error. I do have another delete php but I have put that on the back burning for the time being.
<?php $con = mysqli_connect("localhost","user","password","part_inventory"); // Check connection if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } else { $result = mysqli_query($con, "SELECT * FROM amp20 "); $amp20ptid = $_POST['amp20ptid']; // escape variables for security $amp20ptid = mysqli_real_escape_string($con, $_POST['amp20ptid']); mysqli_query($con, "DELETE FROM amp20 WHERE amp20ptid = '$amp20ptid'"); if (!mysqli_query($con, $amp20ptid)); { die('Could not delete data: ' . mysqli_error($con)); } echo "Part has been deleted to the database!!!\n"; mysqli_close($con); } ?> |
