How to Input Text into a php script

   Frihost Forum Index -> Scripting -> Php and MySQL

Hi

I am just learning php. I can make a script that makes a choice and prints it out.


<?php
$str = 'apple';

if ($str === 'apple') {
echo "Correct?";
exit;
}

else {
echo "Wrong";
exit;
}

?>

I would like this page to have a form to input the text. In this example if the inputed field was apple the answer would be Correct..

Code:


<html>

 <?php
$str = $_REQUEST['fruit'];

if ($str === 'apple') {
//echo "Correct?";
exit;
}

else {
echo "Wrong";
//exit;
}

?>

<form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
<input type='text' name='fruit'>
<input type='submit'>
</form>
</html>



The above code should be saved as a php file and accessed through php enabled webserver. It will give a textbox. once user types a value into textbox and presses submit button, it sends request to itself with the value user has typed in.

Also you could do this:
Code:
 
<?php
$act = $_GET['act'];
$form = "<form action=\"?act=process\" method=\"post\"><input type=\"text\" name=\"fruit\"><br><input type=\"submit\" value=\"submit\"></form>";
switch($act){
case process:
$str = $_POST['fruit'];
if ($str == 'apple') {
echo "Correct?";
}else {
echo "Wrong";
}
break;
default:
echo $form;
break;
}
?>

or simpiler
Code:
 
<?php
$act = $_GET['act'];
if($act == 'process'){
$str = $_POST['fruit'];
if ($str == 'apple') {
echo "Correct?";
}else {
echo "Wrong";
}
}else{
?>
<form action="?act=process" method="post"><input type="text" name="fruit"><br><input type="submit" value="submit"></form>
<?
}
?>

or a little fancier:
Code:

<?php
$act = $_GET['act'];
$form = "<form action=\"?act=process\" method=\"post\"><input type=\"text\" name=\"fruit\"><br><input type=\"submit\" value=\"submit\"></form>";
switch($act){
case process:
$str = $_POST['fruit'];
if ($str == 'apple') {
echo "Correct?";
}else {
echo "Wrong<br>Try Again?<br>";
echo $form;
}
break;
default:
echo $form;
break;
}
?>

as said above, both should be put into a php file. Example: form.php
Demo 1: http://roboguy.frih.net/fun/form1.php
Demo 2: http://roboguy.frih.net/fun/form2.php
Demo 3: http://roboguy.frih.net/fun/form3.php

goto php.net and do a search on switch, break statements. easiest and most effective way to do it


something like this


Code:

<?php
switch ($_GET['variablename'])
{
case 'apple':
echo 'you chose the apple';
break;
case 'orange':
echo 'you chose the orange';
break;
default:
echo 'you didn't choose anything';
}
?>


and you can 'make your choice' by entering it straight into the url.....

filename.php?variablename=apple
gerpg
you can get the script to choose a fruit for you...

Code:

<?

$random = rand(1,4);

if ($random = 1){
$fruit = 'apple'
}
elseif ($random = 2){
$fruit = 'bananna'
}
elseif ($random = 3){
$fruit = 'lemon'
}
else{
$fruit = 'orange'
}

Echo"Today i want to eat a $fruit";

?>


the rand(1,5); says to the server generate a number between 1 and 5. then the if statements ask if the variable is equal to 1, 2, 3, 4 or 5.

Have fun.
