It's no good just telling us it doesn't work. You need to tell us what
happens when you run it. Error messages? Blank screen?

Try Now:

<form action="number.php" method="post">
The computer has picked a number between 1 and 10. Guess the number and
you win!<BR>


Enter your guess:
<input type="text" name="guess" value="" size="3">
<INPUT TYPE="submit" VALUE="Submit my number" NAME="submit"> </form>

Subject: [php] Random number Question


Hi all,

I having a hard time understanding why this won't work. I have a form
which is suppose to pass the guess to the script. Here it is:

the form is guess.php:

<form action="number.php" method="post">
The computer has picked a number between 1 and 10. Guess the number and
you win!<BR>


Enter your guess:
<input type="text" size="3">
<INPUT TYPE="submit" VALUE="Submit my number" NAME="guess"> </form>


The script is number.php:

<?php
echo"The number is:";

srand((double)microtime()*1000000);
$number = rand(1,10);

echo $number;

if($guess = = $number) {
echo"<BR>You have won!";
}else{
print("<BR>Sorry that wasn't the answer");

}
?>

Any help would be appreciated.

Thanks in advance
Jennifer Downey

you've got the "Name" attribute attached to the wrong INPUT element:

<INPUT type="text" size="3" name="guess">
<INPUT type="submit" value="Submit my number">

incorrect syntax here. that should be:
if ($guess == $number) {

better would be:

if (trim($guess) == $number {

this will assure that there's no whitespace in $guess

$guess = = $number
is wrong.

You should write:
$guess == $number

actually

if (intval($guess) == $number {

would be more acuate then the trim ( )
you would eliminate all alpha characters and floating points
saying it has to be a whole integer....

Try something like this and see if it works???
================================================== ==
<?
$another = 'a';
if (isset($guess)) $another = 'another';
echo "
<form action='number.php' method='post'>
<BR>
The computer has picked $another number between 1 and 10.<BR>
Guess the number and you win!<BR>
<BR>
Enter your guess:
<input type='text' size='3'>
<INPUT TYPE='submit' VALUE='Submit my number' NAME='guess'>
</form>";

if (isset($guess))
{
srand((double)microtime()*1000000);
$number = rand(1,10);

echo "The number is: $number<BR>";

if ($guess == $number)
{
echo '<BR>You have won!';
}else{
echo "<BR>Sorry that wasn't the answer";
}
}
?>

================================================== ===============

================================================== =
<?
$another = 'a';
if (isset($guess)) $another = 'another';
echo "
<form action='number.php' method='post'>
<BR>
The computer has picked $another number between 1 and 10.<BR>
Guess the number and you win!<BR>
<BR>
Enter your guess:
<input type='text' size='3' NAME='guess'>
<INPUT TYPE='submit' VALUE='Submit my number'>
</form>";

if (isset($guess))
{
srand((double)microtime()*1000000);
$number = floor(rand(1,10));

echo "The number is: $number<BR>";

if ($guess == $number)
echo '<BR>You have won!';
else echo "<BR>Sorry that wasn't the answer";

}
?>
