ok did i ask a stupic quesiton or did i not provide needed information? i have been sitting here for almost four hours trying to figure this out. i sure could use some help i'll be eternally greatful if someone can lend me a hand here.

if ($_POST['email'] != "")

is causing the problem. The $_POST array does not have an element indexed by 'email'. So you get the error notice.

You should test:

if ( isset($_POST['email']) && $_POST['email'] != "" )

which first tests to see if it is set, then tests to see if it is not the empty string.

ok thank you so much for your help that fixed the line 26 problem now on the same page though i still have the deprecated regi_replace on line 31 and an undefined variable on line 49

$outputForUser = "";
if ( isset($_POST['email']) && $_POST['email'] != "" )
{

$email = $_POST['email'];
$email = strip_tags($email);
$email= eregi_replace("`", "", $email);
$email = mysql_real_escape_string($email);
$sql = mysql_query("SELECT * FROM myMembers WHERE email='$email' AND email_activated='1'");
$emailcheck = mysql_num_rows($sql);
if ($emailcheck == 0){

$outputForUser = '<font color="#FF0000">There is no account with that info<br />
in our records, please try again.';

} else {

line 49 $emailcut = substr($email, 0, 4); // Takes first four characters from the user email address
$randNum = rand();
$tempPass = "$emailcut$randNum";
$hashTempPass = md5($tempPass);

@mysql_query("UPDATE myMembers SET password='$hashTempPass' where email='$email'") or die("cannot set your new password");

$headers ="From: $adminEmail\n"; // $adminEmail is established in [ scripts/connect_to_mysql.php ]
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1 \n";
$subject ="Login Password Generated";

$body="<div align=center><br>----------------------------- New Login Password --------------------------------<br><br><br>
Your New Password for our site is: <font color=\"#006600\"><u>$tempPass</u></font><br><br />
</div>";

if(mail($email,$subject,$body,$headers)) {

$outputForUser = "<font color=\"#006600\"><strong>Your New Login password has been emailed to you.</strong></font>";
} else {

$outputForUser = '<font color="#FF0000">Password Not Sent.<br /><br />
Please Contact Us...</font>';
}

}

} else {

$outputForUser = 'Enter your email address into the field below.';

}

grrr why is this language so stinking confusing

 

[jack202872]

now on the same page though i still have the deprecated regi_replace on line 31

Try str_ireplace instead of regi_replace.

 

[chrismcf]

how if i could just figure out why this variable keeps coming up undefined, sheesh,

$headers ="From: $adminEmail\n"; // $adminEmail is established in [ scripts/connect_to_mysql.php ]

then everything will be perfect!!

says i have it established in connect_to_mysql but it's not...?...

 

[chrismcf]

it kinda bothers me that i have to put pressure on to get help with x10? i dont like that much at all im a really nice person and it makes me look like a jerk...

 

[xxll_martin_llxx]

People do have lives. You just need to be a tad more patient. Posting it in the correct section in the first place would have helped!

 

[chrismcf]

pardon me but i thought this was the right place. 1st and 2nd its taking hours to a response. dont misunderstand people have been helpful but its been very few and far between.

the problem im having im sure is not very complicated i just am so new to php that im not getting it just right.

i do appologise, like i said im not a jerk, just very frustrated with the x10 support, been trying to get into the irc chat all day aswell and i keep getting pat answers to my support tickets and no resolution. i have only actually gotten access 1 time for a few minuets and then it stopped working again.

 

[chrismcf]

gonna close this one up. i looked in the third party applications and programming thread but there doesnt seem to be a way to post in there. not sure where else to post but here but i welcome instruction anytime. thank you guys for the help you have give me so far.
