Create SKU (Stock Keeping Unit) using PHP

[thara]

I need to create the unique SKU (Stock Keeping Unit) name for each products mixed with
product.id,product.name,product.category and product.brand. There is no problem to do it,

i.e.: SKU for a product with

id=13,
name=Bio Clean green and
category=INSECTS KILLERS
brand=HARPIC

becomes : BI-IKHA0013

This is how I tried:

$inm = "Bio Clean green500ml";
$cnm = "INSECTS KILLERS";
$bnm = "HARPIC ";

echo SKU_gen($inm, $cnm,$bnm,20).'<br>';


function SKU_gen($pname, $cat=null, $brand=null, $id = null, $l = 2){
    $results = ''; // empty string

    $str1 = array_shift(explode(' ',$pname));
    $str1 = strtoupper(substr($str1, 0, $l));

    $str2 = array_shift(explode(' ',$cat));
    $str2 = strtoupper(substr($str2, 0, $l));

    $str3 = array_shift(explode(' ',$brand));
    $str3 = strtoupper(substr($str3, 0, $l));

    $id = str_pad($id , 4, 0, STR_PAD_LEFT);

    $results .= "{$str1}-{$str2}{$str3}{$id}";
    return $results;
}

But this function is not working as expected when category of brand values become NULL.

For the benefit of the non-clairvoyant among us, what are you wanting it to look like when there are NULL values?

[thara]

Actually sir, category is not null, only brand would be NULL.

then SKU should be : BI-IK0013

Using your posted code but with $bnm = null , I get BI-IN0020

Which is pretty similar to what you want. (Except I can't see how you are getting IK from the first 2 chars of "INSECT KILLER")

This is my take on things and it does throw an error is an input is null:

<?php
$inm = "Bio Clean green500ml"; 
$cnm = "INSECTS KILLERS";
$bnm = "HARPIC ";

echo SKU_gen($inm, $cnm,$bnm,20).'<br>'; 
function SKU_gen($pname, $cat=null, $brand=null, $id = null, $l = 2){
	if($pname == null) echo "empty<br><br><br>";
	
	$result = "";
	if($pname == "Bio Clean green500ml"){
		$result = "BI-";
	}
	else{
		$result = "XX-";
	}
	
	if($cat == "INSECTS KILLERS"){
		$result = $result."IK";
	}
	else{
		$result = $result."XX";
	}
	
	if($brand == "HARPIC "){
		$result = $result."HA";
	}
	else{
		$result = $result."XX";
	}
	
	$num = 10000 + $l;
	$result = $result.substr($num,1);
	
	if (strpos($result, "XX") !== false){
		echo "There is an error: ".$result;
	}else{
		echo $result;
	}
}
?>   

with a lot of products I'd use switch statements instead of the if then statements.

@NotSunfighter could you show us how that would look with all 6,000 products? 😀

[NotSunfighter]

It doesn't. OP was the one who used 4 integers. But there is also $inm = "Bio Clean green500ml"; $cnm = "INSECTS KILLERS"; $bnm = "HARPIC "; to expand that number significantly.

Nothing to do with the integers. Your code would require 6,000 case statements just for the products. Then there would be hundreds more for the the categories and brands!
