I am trying to make a simple database delete script.
Im fairly new to php and mysql.
I need to access 3 tables in the database to delete all the relevany information for one user.
The articles, penname and users tables.
I adapted the code from a search script I put together.
The following code seems to work if the user has a penname and some articles, however doesnt seem to work if the user has no pennames or articles.
I probably need some if statements.
Thanks for any help.
This is the code:
<h2>Search</h2>
<form name="search" method="post" action="<?=$PHP_SELF?>">
Search for: <input type="text" name="find" /> in
<Select NAME="field">
<Option VALUE="email">Email Address</option>
</Select>
<input type="hidden" name="searching" value="yes" />
<input type="submit" name="search" value="Search" />
</form>
<?
include('setup.php');
//This is only displayed if they have submitted the form
if ($searching =="yes")
{
echo "<h2>Results</h2><p>";
//If they did not enter a search term we give them an error
if ($find == "")
{
echo "<p>You forgot to enter a search term";
exit;
}
// Otherwise we connect to our Database
@mysql_connect($dbhost,$dbuser,$dbpasswd)or die("Connect Error: ".mysql_error());
mysql_select_db($dbname) or die( "Unable to select database");
// We preform a bit of filtering
$find = strtoupper($find);
$find = strip_tags($find);
$find = trim ($find);
//Now we search for our search term, in the field the user specified
// Construct our join query
$data = mysql_query("DELETE articles, penname, users ".
"FROM articles, penname, users ".
"WHERE articles.penname_id = penname.user_id AND penname.user_id = users.user_id AND upper($field) ='$find'");
if ($anymatches == 0)
{
echo "Sorry, but we can not find an entry to match your query<br><br>";
}
//And we remind them what they searched for
echo "<b>The Records You Searched For:</b> " .$find;
}
?>
