Random code...

[ItsWesYo]

5Kscramble.php

<?php
//Check to see if null values were submitted...
if($_POST['question1'] == "") {
?>
<form action="5Kscramble.php" method="POST">
<b>swe</b><br>
<input type='text' name='question1' size='25'><br><br>
<input type="submit" value="Submit!">
</form>
<?php
} else {
//Variables, $x records questions correct. $y is the number of questions.
$x = 0;
$y = 1;
//Check the values of the select questions.
if($_POST['question1'] == "wes") {
$x++;
}
?>
<?php
echo 'You got '. $x .' out of '. $y .' questions correct.';
?>
<?php
}
?>

 

Would there be a way to show a code (ex: 123456789) from a .txt file that I provide on my server to display if ALL questions are answered correctly?

 

Example:

If I have random codes in a text file (seperated by a line) ... like:  123, 234, 345, 456, 567, 987, 876, etc etc

Then, if someone answers ALL the questions correctly, a script would pull ONE of those codes ONCE from the file.

It would display the code on the results page.

Then I go from there by myself.

Yes. Take a look at the file_get_contents() function. You can read a read into a string with that. You'll then need the explode() function to separate out all of your possible codes.

 

Then, use rand() to select a random number between one and the number of items in the array. For example:

 

<?php
$str = '123,345,578,487,685,963';//ive defined a string here - but you can easily retrieve one from a file.
$bits = explode(',',$str);
$n = rand(0,count($bits));
$randomcode = $bits[$n];
echo $randomcode;
?>

Assuming your scenario...a text file with the codes in it, seperated by commas:

 

if ($all_correct)  //Fire only if we know they got all questions right...
    
    {
$file="codes.txt";

$f_handle=fopen($file,"r"); //Open the file for read only.
	   
	   
	   $f_size=filesize($file); //Get the size of the file in bytes.
	   
	   
	   $f_contents=fread($f_handle,$f_size); //Read the entire contents of the file in to a variable.



$code_array=explode("," , $f_contents); //Explode the contents in to an array


$array_count=count($code_array);  //Count the number of members in the array


/*
Now you need to select one of your array elements randomly.  Basically,
that's just a number between 0, and the total number of elements in 
your array, (minus 1, because of the 0-based index of an array)

*/


$random_code=$code_array[rand(0,$array_count-1)];  //Select the random array member.



echo $random_code; //Echo the value back.

     

     }

 

 

Hope that helps?
