Please I need a simple Web application that takes two integers between 1 and 20 from a user
through an interface. When the user submits the form, JavaScript should be used to verify that each
of the inputs from the user is not less than 1 and not greater than 20 and that input 2 is
not less than input 1. Also array of 21 characters in your server side script should be Created. Finally Display
all characters in the array that their positions fall in between the range of inputs from
the user.

PHP code Preferreed Please

read about 'regular expressions' in php or javascript. Its shortly called regex. It wouldnt take more than one line. I have used that before

PHP CODE: note that your form input is what i refer to as '$data'

<php

if (preg_match('/^[0-9] + $/' , $data) && $data < 21 ) {
// do what you want to do here
}
?>




or if your intention is to prevent a zero too from beginning the number use this instead:

<php

if (preg_match('/^[1-9][0-9] * $/' , $data) && $data < 21 ) {
// do what you want to do here
}
?>

<php
/*
note that your first array entry is blank because that first entry is in zero position ie item[0] and ur user is not expected to enter 0.
*/

extract($_POST);

function random_select($num){
$item= array(
'', 'ipad', 'blackberryZ10', 'iphone 6', 'generator', 'coke drink', 'Pepsi drink', 'wall clock', 'black hat', 'violet suit', 'orange drink', 'lemon fruit', 'brown pillow', 'chocolate tea', 'pink bag', 'ashes and dust', 'golden shoes', 'silver chain', 'tomato sauce', 'onion', 'gutter water', 'blablabla'
);
return 'you won '.$item[$num];
}

if (preg_match('/^[0-9] + $/' , $data) && $data < 21 ) {

/*
optional: if you don't want the number to directly match the result in all cases
*/
$data= ceil(($data + rand(1,20))/2);
/*
remove the above line if u want it to match exactly in all cases
*/
random_select($data);

// do other stuff here
} else {
echo 'Invalid selection! Please pick a number between 1 and 20';
}

?>

<?php
$input = $input
if ($input < 1 || $input > 20 ) {
echo "number range exceeded or below expected"
}
?>

dexmundo:
<php
/*
note that your first array entry is blank because that first entry is in zero position ie item[0] and ur user is not expected to enter 0.
*/

extract($_POST);

function random_select($num){
$item= array(
'', 'ipad', 'blackberryZ10', 'iphone 6', 'generator', 'coke drink', 'Pepsi drink', 'wall clock', 'black hat', 'violet suit', 'orange drink', 'lemon fruit', 'brown pillow', 'chocolate tea', 'pink bag', 'ashes and dust', 'golden shoes', 'silver chain', 'tomato sauce', 'onion', 'gutter water', 'blablabla'
);
return 'you won '.$item[$num];
}

if (preg_match('/^[0-9] + $/' , $data) && $data < 21 ) {

/*
optional: if you don't want the number to directly match the result in all cases
*/
$data= ceil(($data + rand(1,20))/2);
/*
remove the above line if u want it to match exactly in all cases
*/
random_select($data);

// do other stuff here
} else {
echo 'Invalid selection! Please pick a number between 1 and 20';
}

?>

Thanks Brother for the code . Really Appreciate. But what i do need is from the array of 1 to 20. If the user select 3 to like 9. Program should display all the content of d array within that range. Like from the fruits and co U supplied.

Thanks so much.
Really New to Php. Just need to get a working code and then build from this.

I have solved this problem. Thanks Guys

the code is technically thesame. Pls delete that line with '$data= ceil($data + rand(1,20))/2);', it will only be useful for a gamble scenario.

i dont know exactly a case study for what you intend doing.

But i guess you are talking about creating a multi-dimensional array.

I need more insight to know what array functions will be used.

Or are you imagining a situation where the user selects not a number but a range of numbers at a single selection? Then specify the ranges here. If that is the case its also possible without using a multi-dimensional array.

I don't fully get what the task look like!
