 These are getting tougher as we go! I'm srarting to have difficulty with order. Getting things to print out where I want etc.
This code looks a bit sloppy due to all the html formatting Iv'e done to make it look the way I want. I gotta think that includes may change that :) (Next time I will make an unformatted code to post, so others looking at this can use it for a reference)
Ok, heres my code:


<?php
// [ Define Vars ]
$action = $_POST['action'];
$entry = $_POST['entry'];
$entry_to_find = $_POST['entry_to_find'];
$delete = $_POST['delete'];
$modify = $_POST['modify'];

// [ Open the file for Reading ]
if($fh = fopen("basic/email.txt", "r")){
flock($fh,LOCK_SH);
while(!feof($fh)){
$file[] = fgets($fh);
}
flock($fh,LOCK_UN);
fclose($fh);
}
?>

<table border="0" width="98%">
<tr>
<td width="30%" valign="top">
<?php
// [ Add An Entry ]
if($action == "add_entry"){
if($fh = fopen("basic/email.txt" , "a")){
flock($fh,LOCK_EX);
if($entry_to_add != ""){
fputs($fh, $entry_to_add . "\n");
flock($fh,LOCK_UN);
fclose($fh);
print("<center><b>Added</b> <i>$entry_to_add</i></center>");
}else{
print("<b><center><font color=red>Nothing to Add</font></center></b>");
}
}
}
?>

<table border="0" width="95%" cellpadding="0" cellspacing="0">

 I sure had trouble with an extra black space sneaking into my variables -- thanks go to Lestat for showing me how to use trim(); to clear that issue up!

Working link: http://www.algore.org/~admin/m...le_advanced.php

And the code follows (note that the code is visible the link above I'm testing out the other new function Lestat showed me highlight_file();



<?
// Using your email script from last week, add
// functionality so that you will only send to one email
// address per domain (to avoid spamming the same
// domain). Also make sure you have filelocking in place.

$file_directory = '/Users/admin/Sites/';
$error = 'I could not open the email file! Verify permissions are correct and the absolute path to the file.';
$file_contents = file("$file_directory/emaillist.txt");
sort($file_contents);
$sizeof = count($file_contents);

// if they aren't adding a new address, show the form
if($_POST['action'] != "add") {
?>
<html><body>
<i>You may add your name to our public list below:</i> <br />
<form method=POST action="<? echo($PHP_SELF); ?>">
<input type="hidden" name="action" value="add"><br />
Your Name:
<input type="text" name="name" size="20"><br />
Email Address:
<input type="text" name="address" size="18"><br />
<input type="submit" value="Add New Email">
</form> <br />

<i>Current members:</i> <br /> <br />
<!-- Begin Table of email addresses -->
<table border="1">
<tr><td><b>NAME:</b></td><td><b>EMAIL:</b></td></tr>
</body>
</html>
<?
for($i=0; $i < $sizeof; $i++) {
$email = explode(":", $file_contents[$i]);
print("<tr>");
print("<td>".$email[0]."</td>");
print("<td>".$email[1]."</td>");
print("</tr>");
}

print ("</table>");
// add the new email address to the file
}
else
{
if($filehandle = fopen("$file_directory/emaillist.txt", "a"))
{
// is the submitted email address in valid format?
if(ereg("([[:alnum:]\.\-]+)(\@[[:alnum:]\.\-]+\.+)", $_POST['address']))
{
$domain = explode("@", ($_POST['address']));
for ($i=0; $i < $sizeof; $i++) {
$stored = explode("@", $file_contents[$i]);
$stored[1] = trim($stored[1]);
if ($stored[1] == $domain[1])
{
print("Sorry, someone from your domain has already registered.");
exit;
}
}
flock($filehandle, 2); // lock emaillist.txt
fputs($filehandle, $_POST['name'].":".$_POST['address']."\n");
flock($filehandle, 3); // unlock emaillist.txt
fclose($filehandle);
print("Successfully added <b>".$_POST['name']."</b> to the file");
} else {
print("Your email address appears to be invalid, please try again.");
exit; }
}
else
{
echo($error);
}
}
highlight_file("mailfile_advanced.php");
?>
