Hi: I can't seem to figure out how I would display the words the user enters in an ordered list on the bottom of the page in the <div id="guesses"> area. A hidden form variable is used to store all the previous guesses. (no cookies, no session variables).

Also, how do I get the guesses to appear in the top of the page so that it looks like this:

Array

(

[myguess] => eee

[alltheguesses] => aaa|ccc|ddd|ggg

)

This is what I seem to be getting:

Array

(

[myguess] => yy

[allTheGuesses] =>

)

<?= '<pre>' . print_r($_POST,true) . '</pre>'; ?>
<?
    $WORDS = array("grape","apple","orange","banana","plum","grapefruit");
    define ("GUESSINDEX",3);
    define("THEWORD",$WORDS[GUESSINDEX]); 


foreach ($WORDS as $val){
    
    if ('banana' == $val)
    echo 'found it.';
     else 
    echo 'not found.';
}

if (in_array('plum',$WORDS == true)){
    
}

foreach ($guessesarr as $val)
echo "<li> $val</li>";

foreach ($WORDS as $val) echo "$val | ";
echo "<br>";
echo implode(' | ',$WORDS);

?>

<input type="hidden" name="allTheGuesses" value = "<? echo $_POST['allTheGuesses'] . '|' . $_POST['myguess']; ?>">

You should add sanitation and validation to all data received.

Oh..that makes sense..I overlooked that part.

Thanks!

How would I go about using this statement?

The builtin Apache global $_SERVER[REQUEST_METHOD] was used to determine if the incoming request was a POST or a GET.

jcbones · October 8, 2011

$_SERVER

This will just tell if the server was sent a GET or a POST request. It is usually used like:

<?php
if($_SERVER['REQUEST_METHOD'] == 'post') {
//Do
}

<?php
if($_SERVER['REQUEST_METHOD'] == 'post') {
//Do
}

But what am I supposed to put in after the if statement? That's where I'm lost. Also, where does the code go if I were to put it in here?

<?= '<pre>' . print_r($_POST,true) . '</pre>'; ?>
<?

    $WORDS = array("grape","apple","orange","banana","plum","grapefruit");
    define ("GUESSINDEX");
    define("THEWORD",$WORDS[GUESSINDEX]); 



if (in_array('plum',$WORDS == true)){
    
}

foreach ($guessesarr as $val)
echo "<li> $val</li>";

foreach ($WORDS as $val) echo "$val | ";
echo "<br>";
echo implode(' | ',$WORDS);

I wasn't sure exactly how the flow of the script was suppose to operate. I did notice a lot of redundancy, so I re-wrote portions, trying to keep the output the same.

<?php //echo '<pre>' . print_r($_POST,true) . '</pre>'; //debugging?>
<?php
    $WORDS = array("grape","apple","orange","banana","plum","grapefruit"); //add or take away as many as you like;
    define ("GUESSINDEX",3); //define the desired word, count starts at 0.
    define("THEWORD",$WORDS[GUESSINDEX]); //defines the actual word.
$count = (isset($_POST['count'])) ? (int)$_POST['count'] : 0; //keep count of how many times the form is submitted WRONG.
$all_guesses = (isset($_POST['allTheGuesses'])) ? $_POST['allTheGuesses'] : NULL; //our guesses.
$message = 'It\'s time to play the guessing game! (1)'; //if POST isn't the request method, this will be our message.
if($_SERVER['REQUEST_METHOD'] == 'POST') {
if($_POST['myguess'] == THEWORD) {
	$message = 'You guessed ' . THEWORD . ' and that\'s CORRECT!!! (3)'; //if the answer is correct.
}
else {
	++$count; //if the answer is incorrect, increment the count.
	$all_guesses .= '|' . $_POST['myguess']; //add the guess to our wrong list.
	if(empty($_POST['myguess'])) { 
		$message = 'C\'mon, guess something (2)'; //if the guess is emtpy.
	}
	elseif(!in_array($_POST['myguess'], $WORDS)) {
		$message = 'Hey, thats not even a valid guess. Try again (5)'; //if the guess doesn't exist in the array.
	}
	else {
		$message = "Sorry {$_POST['myguess']} is wrong. Try again (4)"; //if the guess is just wrong.
	}
}
}

?>
