I threw this together to try and help you un-blacklist many at once.
STEP 1
Create a plain text file called unblacklist.txt.
Add all of the email addys to that file (one per row).
These are the addys that will be removed from the blacklist.
STEP 2
Copy the following code to a new file and save it as unblacklist.php.
Edit lines 2-6 to have the same values as your PHPList config file.
STEP 3
Upload both files to your site and visit http://yoursite.com/unblacklist.php
<?php
$database_host = "myhost"; /* AVAILABLE IN YOUR CONFIG FILE */
$database_user = "myuser"; /* AVAILABLE IN YOUR CONFIG FILE */
$database_password = "mypassword"; /* AVAILABLE IN YOUR CONFIG FILE */
$database_name = "myDBname"; /* AVAILABLE IN YOUR CONFIG FILE */
$table_prefix = "phplist_"; /* AVAILABLE IN YOUR CONFIG FILE */
$conn = mysqli_connect($database_host, $database_user, $database_password, $database_name);
$good1 = $good2 = $good3 = 0;
$bad1 = $bad2 = $bad3 = 0;
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
$file = fopen("unblacklist.txt","r"); // Input file.
while(!feof($file)) {
$myline=fgets($file);
$myline=rtrim($myline);
$sql = "SELECT id FROM ".$table_prefix."user_user WHERE email = '".$myline."';";
if (mysqli_query($conn, $sql)) {
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_array($result);
$uid = $row['id'];
} else {
echo "Could not get userid for: ".$myline." : " . mysqli_error($conn)."<br />";
};
$sql = "UPDATE ".$table_prefix."user_user SET ".$table_prefix."user_user.blacklisted = 0 WHERE email = '".$myline."';";
if (mysqli_query($conn, $sql)) {
echo "$myline<br />";
$good1++;
} else {
echo "$myline user_user.blacklisted = Error: " . mysqli_error($conn);
$bad1++;
};
$sql = "DELETE FROM ".$table_prefix."user_blacklist WHERE email = '".$myline."';";
if (mysqli_query($conn, $sql)) {
$good2++;
} else {
echo " user_blacklist deletion = Error: " . mysqli_error($conn);
$bad2++;
};
$sql = "DELETE FROM ".$table_prefix."user_blacklist_data WHERE email = '".$myline."';";
if (mysqli_query($conn, $sql)) {
$good3++;
} else {
echo " user_blacklist_data deletion = Error: " . mysqli_error($conn) ."<br />";
$bad3++;
};
$sql = "DELETE FROM ".$table_prefix."user_user_history WHERE userid = '".$uid."' AND summary LIKE 'Added to blacklist%';";
if (mysqli_query($conn, $sql)) {
$good3++;
echo "SUCCESS";
} else {
echo " user_user_history deletion = Error: " . mysqli_error($conn) ."<br />";
$bad3++;
};
};
fclose($file);
mysqli_close($conn);
echo "$good1 user_user.blacklist set to 0 $bad1 failed<br />$good2 user_blacklist rows deleted $bad2 failed<br />$good3 user_blacklist_data rows deleted $bad3 failed";
?>
This should do what you want, but PLEASE backup your database before you do this.
