syntax question

[deepman007]

Hi

 

I'm new to PHP and I saw this "$sku_stock = (allowBackOrders) ? "" : " AND S.SKU_Stock > 0";  "

 

What does it mean? I dont understand "? :"

 

thanks

This is called the ternary operator, it is the short way of writing an if/else statement.

 

This:

$sku_stock = (allowBackOrders) ? "" : " AND S.SKU_Stock > 0";

 

Is the short version of writing:

<?php

if (allowBackOrders){
   $sku_stock = "";
} else {
   $sku_stock = " AND S.SKU_Stock > 0";
}

?>

you can put Query " AND S.SKU_Stock >0 to a varible ?

 

Thanks

yes, sure. it's a string:

 

$var = " AND S.SKU_Stock > 0";

If you still need explanations, check the manual:

Scroll down a bit.
