Question

I have a question. To make things more clear, I will give an example:

Values are submited in a form. I have:

Value1: Blanc
Value2: Titanium
Value3: 100
Value4: 150
Value5: China

I want to get a value 6 that has this structure:

BLTIT-100150-CH

Value6 has: (2 chars from value1) + (3 chars from value5) +(-)+(value3+value4 +(-)+(2 chars of value5).
Is there way to make that with PHP Or JavaScript?

Answer 1

In PHP:

$Value6 = strtoupper(substr($Value1,0,2) . substr($Value2,0,3) . '-' . 
                     $Value3 . $Value4 . '-' . substr($Value5,0,2)
                    );

Of course, this assumes your variables are set locally. If you’re getting them straight from the POST, you need $_POST['Value1'] instead of $Value1, etc.

Look up substr – it takes a subsection of a string (known as a substring), given a starting point and a length.:
http://php.net/manual/en/function.substr.php

The . is the PHP string concatenation operator – it joins two strings together.

strtoupper converts a string to uppercase (see http://php.net/manual/en/function.strtoupper.php)
