What version of PHP are you running? Try concatenating the variable (just in case)

echo "<a href=" . $_SERVER["PHP_SELF"] . ">Play Again</a>";

And if that still doesn't work, then try

echo "<a href=" . $HTTP_SERVER_VARS["PHP_SELF"] . ">Play Again</a>";

I am running 4.3.2 and it is not finding the $letters variable in the ereg()'s which is weird because the ereg defines it to store the values.

cgraz

i don't see $letters defined before this line:

if (ereg($var, $letters))

Cgraz

Tekron-X

this is weird I think wrox screwed up lol
I think they ment it too be switched or something and define letters with the [A-Z]
I get the PHP_SELF error here too

            $links .= "<a href='$_SERVER['PHP_SELF']?letters=$letters$var
                        &word_number=$word_number'>$var</a>  ";

cgraz

copy and paste the error. I don't see why you would get a PHP SELF error. however you are encompassing your href in single quotes, then use single quotes around PHP_SELF.

should be

$links .= "<a href=\"" . $_SERVER["PHP_SELF"] . "?letters=" . $letters$var
                        . "&word_number=" . $word_number . "\">" . $var . "</a>";

sry I am late I have been sick for the past couple days here is the error

Notice: Undefined index: 'PHP_SELF' in c:....................\hangman.php on line 57

edited path even though no one can access my director because it is only a local server.

Tekron-X

now using that code you cave me above I get this parser error

Parse error: parse error, unexpected T_VARIABLE in c:.....................\hangman.php on line 58

It's bad practice, but try not adding anything to the <form action="">.

That generally posts/gets to php self anyway.

Tekron-X

sry to say but this does not use a form 🙂

cgraz

yeah, i forgot a period in my post. I just tried this and it works properly.

$links = "<a href=\"" . str_replace("/", "", $_SERVER["PHP_SELF"]) . "?letters=" . $letters . $var
                        . "&word_number=" . $word_number . "\">" . $var . "</a>";

That shouldn't produce any errors. If it does, i'm curious to know what version of PHP you are running.

Ok we got rid of the PHP_SELF error now what do we do about the letters error I realize it is not defined what should I do to the eregs look please and see where this script makes that monster error and how to get around it.

cgraz

well you shouldn't do anything to the eregs, you just need to define $letters. I have no idea where it's coming from orw hat it even is for me to be able to tell you what to do. You just need to get the value of $letters into this script or define it somewhere.

I think they wanted the ereg $letters to be the holder of the ereg so I think there is suppose to be another value between the $word[$i] and the $letters.

cgraz

so somethign like this?

if($letters = ereg(pattern here, $word[$i])

Cgraz

Tekron-X

ok here is what I did I replaced the ereg with this

if (ereg("[A-Z]", $word[$i], $letters))

which caused another problem lol but not worried about it yet but I am also getting a PHP_SELF error on this line

echo "<a href=' . $_SERVER['PHP_SELF'] . '>Play Again</a>";

Tekron-X

ok fixed the php self prob with this
echo "<a href='" . $_SERVER['PHP_SELF'] . "'>Play Again</a>";

no to find the problem with the game lol it always says I win I don't even get to pick a letter.
