#9544 — PHP Contact Form, mt-rand(), problem Validating 1 input

Hi, Newviw here;

Win 7 Home Premium, XAMPP 1.7.3, PHP 5.3,

Two pages:  Form.php, check.php (& thanks.html).
    They work fine; sends e-mail, formatted, and readable.


Form.php:
$d=($a.$b.$c);
    echo "Your code is : " .$d." Enter it in the box below, including 
dashes : <br />";

<form action="Check.php" method="post">
  <b>Your Code: </b><input type="text" name="code" size="10 
maxlength="14" /><br /><br /> ...

BUT:  When I begin to add some security, things quit working.

1st, I add to form.php an mt-rand() build of a random code assigned to $d.

$d=($a.$b.$c);
    echo "Your code is : " .$d." Enter it in the box below, including 
dashes : <br />";

Works OK.

Check.php:
Now, when I try to validate the 'code' in check.php, things stop working.

$code = check_input($_POST['code'], "Enter Your Code");
stops everything in its tracks.

Any comments, advice, leads much appreiated.

TIA.

Twayne`

WOW, not a good way to get help.  PE was correct.

Supply the code to the failing function and someone may be able to help.

But I would first check the attitude at the door.

Consider the source, Scott.

Twayne is a nym-shifting numbskull from way back. Over in alt.home.repair, many of us 
have had him killfiled for ten or fifteen years. Every year or so, he nymshifts to evade the 
filters; he'd probably do it more often if it didn't take him so long to figure out that nobody's 
reading his posts. He's just recently showed up in some of the computer software NGs, and 
this is at least the second nym of his that I've had to KF since that happened.

I did, Scottie. I posted relevant code and also offered to  provide full 
code if it was necessary. Our "friend" simply decided to remove same in 
his response.  Not good treatment of an admitted newbie.

OK here is your Original Post:

1. where is the relevant code of check_input(), the function that you 
said is failing?

2. Where did you say that you will provide full code?

3. Best advice here, IMHO, if you don't like a reply then just ignore 
it.  If you bite back then you lose.

It is not that people do not want to help, but their time is very 
valuable to them and like to get to the straight skinny.  This is 
probably why PE pointed you to how to ask good questions in here.

Will await the code.

It is one reason why I did that.  The underlying reason is that a person who 
would even invest the time to post something *readable* does not deserve to 
read as answer anything else except advice how to do just that.

Good answers, which require a corresponding amount of free time by the 
person writing them, are to be deserved by posting smart questions, i. e. by 
investing a considerable amount of free time for trying to answer them by 
oneself, and then put them in proper words if that did not work, before they 
are posted.  Who thinks they could save all their free time by just posting 
questions to others should not be surprised if the latter people are not 
willing to invest any of their free time for the answer that the questioner 
meant to save.  Quid pro quo.
 
> Will await the code.

As others pointed out later, apparently “Twayne” is anything but a newbie.  
Please do not feed the troll, then.
