This is fine, when you post a comment it posts your data like this from a form using this code
index.php (only relavent code shown)
-
-
<?php
-
$text = htmlspecialchars(stripcslashes($_POST['input'] . "\n"));
-
$username = htmlspecialchars(stripslashes($_POST['username']));
-
$color = $_POST['color'];
-
$font = $_POST['font'];
-
$ip = $_SERVER['REMOTE_ADDR'] . "\n";
-
$ip1 = mysql_real_escape_string($_SERVER['REMOTE_ADDR']);
-
$_SESSION['username'] = $username;
-
$_SESSION['color'] = $color;
-
$current_time = mysql_real_escape_string(time());
-
-
$data[] = "\n".trim("\nusername=".htmlspecialchars_decode(substr($username, 0, 10)) . "\r");
-
$data[] = trim($current_time) . "\r";
-
$data[] = "ip=".trim($ip1) . "\r";
-
$data[] = "color=".trim($color) . "\r";
-
$data[] = "font=".trim($font) . "\r";
-
$data[] = "message=".htmlspecialchars_decode(trim(substr($text, 0, 75)) . "\r");
-
$data[] = trim("###");
-
-
//followed later by
-
-
-
$datal = file_get_contents("data.line");
-
if (stristr($datal, $_SERVER['REMOTE_ADDR'])) {
-
-
echo "<a href='http://helraizer.dnsalias.net/Chat/index.php5?action=delete'><b>Delete your post</b></a>";
-
-
$_SESSION['a'] = 1;
-
-
if (isset($_SESSION['a']) && $_GET['action']=="delete") {
-
?><table align='center'><tr><td><b>Post Deletion</b></td></tr><tr><td>
-
<?php
-
$us_name = $_POST['user'];
-
echo "<form align='center' name='post' action='delete.php5' method='post'>";
-
echo "<label align='center' for='user'>Please enter the username you used in your post:</label>";
-
echo " <input type='text' align='center' id='usera' name='usera' size='10' maxlength='10'>";
-
echo " <input type='submit' value='Delete!' name='submita' id='submita'>";
-
-
?>
-
</form></td></tr></table><br><br><br>
-
<?php
-
}
-
}
-
?>
Which is fine. It adds the new post after the previous, starting on a new line each time. It must do this or the script won't read be able to read the file at all, or will pull the wrong information out and thus break the formatting.
function.php
-
-
<?php
-
function ddfm_flock($handle, $param) {
-
-
global $enable_file_locking;
-
-
if ($enable_file_locking == TRUE) {
-
return flock($handle, $param);
-
} else {
-
return TRUE;
-
}
-
?>
-
}
Then in finally in delete.php
-
-
<?php
-
if (isset($_POST['submita'])) {
-
-
$entries = file_get_contents("data.line");
-
$entries = (array )explode('###', $entries);
-
-
foreach ($entries as $entry) {
-
$data_t = explode("\r", trim($entry));
-
-
if ($data_t[0] == "username=" . $_POST['usera']) {
-
-
$data = array();
-
foreach ($data_t as $dt) {
-
if (strpos($dt, '=') != false) {
-
$k = substr($dt, 0, strpos($dt, '='));
-
$v = substr($dt, strpos($dt, '=') + 1, strlen($dt) - strpos($dt, '='));
-
$data[$k] = $v;
-
}
-
}
-
$data['timestamp'] = $data_t[1];
-
-
-
if (isset($_POST['usera'])) {
-
if (is_string($_POST['usera'])) {
-
$item = "username=" . $_POST['usera'];
-
}
-
}
-
-
$the_ip = "";
-
$entries = file_get_contents("data.line");
-
$entries = (array )explode('###', $entries);
-
foreach ($entries as $entry) {
-
$data_t = explode("\r", trim($entry));
-
if (trim($data_t[0]) == $item) {
-
foreach ($data_t as $d) {
-
if (strpos($d, 'username=') === 0) {
-
$the_ip = substr($d, 9, strlen($d) - 1);
-
}
-
}
-
}
-
}
-
-
$entries = file_get_contents("data.line");
-
$entries = (array )explode('###', $entries);
-
-
// recreate file
-
$handle = fopen("data.line", "w");
-
-
if (ddfm_flock($handle, LOCK_EX)) { // do an exclusive lock
-
-
foreach ($entries as $entry) {
-
-
$data_t = explode("\r", trim($entry));
-
-
if (trim($data_t[0]) != "") { // if valid item
-
-
foreach ($data_t as $d) {
-
if (strpos($d, 'username=') === 0) {
-
$test_ip = substr($d, 9, strlen($d) - 1);
-
}
-
}
-
-
if ($test_ip != $the_ip) { // put back
-
-
foreach ($data_t as $d) {
-
fwrite($handle, $d . "\r");
-
}
-
fwrite($handle, "###\r");
-
-
} else {
-
// skip items from this IP
-
}
-
-
}
-
}
-
-
ddfm_flock($handle, LOCK_UN); // release the lock
-
} else {
-
}
-
}
-
}
-
?>
which adds a blank line to the chatbox and thus the chatbox returns the wrong values and format.. How would I stop it from adding this extra line? If I change fwrite($handle, "###\r") to fwrite($handle, "###") it
makes data.line format as:
-
-
CHATBOXTEXT

The username of the next post starts on the same lines as the ### and the same problem occurs
Instead of reading
[helraizer]bit of a bug, I admit (should be yellow)
[Fjar] I love you my Sam!! ^_^ (should be yellow)
[helraizer]I love you too, my Fjar!! <3 (should be blue)
it reads
[palab]palab
[202416953][202420306]
helraizer
^all of them white (the default if $color is not specified or different to those it is supposed to be).
How would I get it to, when I delete a post, print the comment (all information) starting on the line after the previous ###?
Hope that makes sense. Just ask if you need more information.
Thanks,
Sam
