PHP - Making A Secure Delete Button (best Way?)

Im displaying the results of a database by using a while loop... so Im trying to figure out how to delete some entries from the datbase. What I wanted to do is add a button in each result that will have the value "delete"... but I cant figure out how to do this. Im kinda new to mysql. I just want it so when I click the button the result will get deleted from the database.

I did some research on this but I cant really grasp the examples.

Can anybody help me out with this one?

Thanks!

Hi

I have made this simple login page by setcookies function and I want now to make a logout button.

Here the code 

<?php
/*
PHP Form Login Remember Functionality with Cookies
*/
if(!empty($_POST["remember"])) {
	setcookie ("username",$_POST["username"],time()+ 3600);
	setcookie ("password",$_POST["password"],time()+ 3600);
    setcookie ("color",$_POST["color"],time()+ 3600);
    //3600 = 1 hour
    //86400 = 1 day
    //(8640*30) = 1 month
	echo "Cookies Set Successfuly";
} else {
	setcookie("username","");
	setcookie("password","");
    setcookie("color","");
	echo "Cookies Not Set";
}
?>
  <form action="Cookies.php" method="post"
 style="border: 2px dotted blue;
 text-align:center; width: 400px;">

 <p>Welcome <?php echo ( !empty($_POST ['username']) ) ?
  $_POST ['username'] : 'USER'; ?>
    </p>
	<p>Username: <input name="username" type="text" 
    value="<?php if(isset($_COOKIE["username"])) 
    { echo $_COOKIE["username"],( !empty($_POST ['username']) ) ?
  $_POST ['username'] : '';} ?>" >
	</p>
	<p>Password: <input name="password" type="password" value="
    <?php if(isset($_COOKIE["password"])) 
    { echo $_COOKIE["password"]; } ?>" >
	</p>
    <p>Choose Your Favorite Color: <input name="color" type="color" 
    value="<?php if(isset($_COOKIE["color"])) 
    { echo $_COOKIE["color"]; } ?>">
	</p>
	<p><input type="checkbox" name="remember" /> Remember me</p>
	<p><input type="submit" value="Login"></p>  
</form>

Any idea ??

I have a download-list, and want to have a delete-button/link at each file. I have tried different codes, but i'm new to php and need some help.

if ($handle = opendir('files/engelsk/')) {
               while (false !== ($file = readdir($handle)))
                  {
                      if ($file != "." && $file != "..")
                  {
                        $en .= '&raquo; <a href="/files/engelsk/'.$file.'">'.$file.'</a>&nbsp;&nbsp;-&nbsp;<i><a href="#">Delete file</a></i><br />';
                      }
                   }
              closedir($handle);
              }

It's the "<a href="#">Delete file</a>" I want to be the delete-button.

Please help!

Hi I've been scouring the net and I cant find anything that works. Can someone tell me how to put a delete button next to each record? Any help is appreciated, thank you!

Code: [Select]
$term = strtolower ($_POST['term']);   
$sql = mysql_query("select * from $table where first like '%$term%' or last like '%$term%'");
while ($row = mysql_fetch_array($sql)){     
echo 'ID: '.$row['id'];     
echo '<br/> first: '.$row['first'];     
echo '<br/> last: '.$row['last'];
echo '<br/> phone: '.$row['phone'];   
echo '<br/> mobile: '.$row['mobile'];   
echo '<br/> fax: '.$row['fax'];     
echo '<br/> email: '.$row['email'];     
echo '<br/> web: '.$row['web'];         
echo '<br/><br/>';     }   
?>
 
</p>

Hello,

I am new to php, and what I need to know and learn is a part of an assignment I normally wouldn't ask for help on the net for an assignment but my teacher is not very helpful and other students are struggling too! I have searched the net inside and out and have tried many things. My problem is that I am trying to remove a line from an array by clicking a delete button.

The outpur I need is:

a line of text that comes from my text file after it is exploded into an array | With a delete button here
next line of text that comes from my text file after it is exploded into an array | With a delete button here
etc

I have managed to write this much myself -
Code: [Select]
<?php
$file = fopen('fav/fav.txt', 'r');
$file = file_get_contents('fav/fav.txt');
$file_array = explode("\n",$file);
array_pop($file_array);
foreach($file_array as $line) {
echo "<form method='post' action=''>".$line.
"<input type='submit' name='post' value='delete'><br>";
$fh = fopen("fav/fav.txt",'w');
foreach ($file_array as $line) {
fwrite($fh,$line."\n");
}
fclose($fh);
} 
?>
The array_pop deletes from the bottom instead of the line the button is next too, I realise I will need to use and if statement but this is the closest I have gotten.
Thanks in advance!!!

I am new to php and I thought it best to start by using a CMS and creating small functions to extend it's functionality. I will start by explaining the situation around what I want to do. I am trying to create a module for the drupal CMS. The module I am trying to create I am creating for my girlfriends son (for when it is complete he will be the one maintaining it through the web interface). He wants a game server (WOW) and a web site that once they create an account on the web site it will create an account on the game server as well. If I understand the way this works correctly for this game server to work you need a logon database and then a character and world database for each realm you have. With that basically what happens is you go to the drupal web site and click create account, input a username, email address and password and agree to terms of service. Then drupal does some checks and writes the information to the drupal database and with the module I creating it will write to the logon database as well. I am working on the admin forms so you can edit how many realms the server has the sql statement to login to the game and add and delete realms. I have been looking at an example of a form for drupal here http://drupal.org/node/717746 but have converted it to my purpose and it brings up some questions here is what I have so far:

If max_realms is set to a large number the way I see it you would have to hard code everything into the php file. Instead of that could you not remove from the if(isset) and have it that when they click on the add realm button check to make sure the textfield contains a number if it doesn't return an error if it does contain a number make sure it is not greater then max_realms and then use a start count and adding that number to all the arrays for that realm and validate all the information is what you expect. I think this would work for adding realms, I think where the problem would come in is in deleting realms (or it could be me over thinking it). For example if you have max_realms set to 4 you could have 5 the one default one that can't be deleted plus 4 others and the ones that can be deleted would be called realm1 - realm4 if you delete the first 2 you would minus count by 2 so if you clicked add realm again it would try and create realm3 which already exists. Is there another way on doing this that you could create the realms and delete them and it not try to add realms with the same array name?

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.

Hi, I'm doing a simple e-mail using localhost, while doing the rest, I realized I need a delete button for it. Is there a simple way to delete the message when the user opens the mail content?

I have a dynamic script and need to create a click event function with JavaScript to delete the row which has a checkbox checked when the delete button is pressed. 
 
 
This is being implemented with PHP and as now serves as light code for this matter at hand. I was only able to delete all rows. I have my efforts with the js functions too.     <script type="text/javascript">
   var counter = 1;
   var limit = 6;
   function addTextArea() {
    if (counter == limit-1) {
    alert("Maximum limit " + counter + " sorry");
    return false;
    }
    else {

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

Hi,   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'm not amazing with PhP, so excuse me if it looks terrible xD I've taken tutorials, edited them to fit my wanting and tried it out, it seems to deny anything other than an image type, but could it be abused?

<div id="image-upload">

if ($_FILES['image']['error'] !== UPLOAD_ERR_OK) {
die();
}

$imgtype=$_FILES["image"]["type"];
$ext= GetImageExtension($imgtype);

$query_upload="INSERT into `images_tbl` (`images_path`,`submission_date`,`image_title`) VALUES

mysql_query($query_upload) or die("error in $query_upload == ----> ".mysql_error());
