I'm trying to add 2 to the price for each time the variables below isset (contrarily, I don't want to add 2 if it's empty) . I have pasted my current sample code below. It works with the first statement by itself, but when add more than one if statement it causes an error. Please advice what the best way to handle this is? I'm sure it's very simple...but I'm missing something. Still a beginner. Thank you in advance for the help!
<?php
$price = $price + 2;
// same as
$price += 2;
?>
Something to note about isset(), even if the variable has no value isset() will evaluate to true; you mention you don't want to add if a value is empty so you might want to update the script a bit
<?php
// isset() will see the variable below as 'set'
$value = '';
// maybe something like the line below will be more effective
if ($field_Charger > 0) {
$price += 2;
}
// etc.
?>
