stupid simple calculation workflow isn't simple

Hi @Cliff, you need to return a JSON or XML object.

if you can use zsh (with input as argv) this below works

 

#!/bin/zsh

myVar=$(( $1 *0.029 +0.3))
myVar_f=$(printf "%.2g" $myVar)

cat << EOB
{"items": [

	{
		"title": "your fee is $myVar_f",
		"subtitle": "your input was $1",
		"arg": $myVar_f
		}
	

	

]}
EOB

@giovanni tyvm but is there any way to stick with PHP so I can be comfortable editing further and to learn for other snippets?

  1. In PHP, I tried both `return` and `echo` of JSON and it didn't work like your script did
  2. I want the result to pass through to the clipboard action so I can auto-paste

You misunderstand how Alfred works. There is only one argument to your script, $argv[1], which contains everything the user entered. You’re using $argv[2] etc., which don’t exist.


You also can’t just echo a result from a Script Filter. You must output JSON in the format expected by Alfred.

 

Try this code instead:

<?php

$gross = $argv[1];  // user input
$pct = 0.029;
$flat = 0.3;

$sum = $gross * $pct + $flat;

// Alfred feedback JSON
$item = array('title' => "$sum", 'arg' => "$sum");
$json = json_encode(array('items' => array($item)));

echo $json;  // send JSON to Alfred
?>

However, when I change it from "with input as argv" to "with input as {query}" (and changed your code to either $gross = {query}; or $gross = "{query}"; then it wouldn't work.

 

Then you've done something wrong. And you should almost always use "with input as argv", anyway. It works much better.

For example, what else is available within the $argv array?

 

Nothing else. ARGV is where command-line arguments are stored. That's just how UNIX programs work.

 

It's not mentioned in Alfred's documentation because it's a topic for your programming language's docs.
