Take some text from a PHP text box

I want to make a PHP script that will have two textboxes.
After you hit Submit, I want to get the first two letters from the first textbox. Then, all the text from the second, then post it to another webpage.
First Name: Major
Last Name: Geeks
then after you press OK, it will go to getpw.php?pw=mageeks
Then, I also need to know how to echo the text from the parameter.
Sorry if i didn't explain it write.

 

basic html:

Code:

<form action=postpw.php method=post>Name: <input type=text name=n><br>Password: <input type=password name=pw></form>

postpw.php:

PHP:

<?php
$t='getpw.php?pw='.urlencode(substr($n,0,2).$pw);
header("Location:$t");
echo("Logging in... <a href=$t>Please click here if your browser doesn't redirect automatically</a>")
?>

 

Not exactacly. i need a code to figure out the password. i set up email addresses for everyone in my extended family, and i want this script to figure out their password. first two letters of their first name, all of their last name

 

Like this?

PHP:

substr($firstName,0,2).$lastName

 

But i want it to echo. How can I make it a button command?

PHP:

$name=substr($firstName,0,2).$lastName
echo('$name')


But how do u make it a button command?

 

A PHP file is called by a form or link. The PHP file makes the returned page.
To make a button return a PHP page, placing it in a form on the calling page is the normal way

Code:

<form action=postpw.php method=post>First Name: <input type=text name=firstName><br>Last Name: <input type=text name=lastName><br><input type=submit></form>

This form will call postpw.php when submit button is clicked. You can then have

PHP:

<?php
$name=substr($firstName,0,2).$lastName;
echo($name);
?>

in postpw.php to echo the result as the next page. If you would rather have it use only one page, you could use JavaScript instead, by placing onclick code in a button tag.
