Syntax

Available syntax examples

String data

Scope data:

["name" => "Jakub Miškech"]

• '{{name}}' -> 'Jakub Miškech'
• '{{fn.strtoupper(name)}}' - 'JAKUB MIŠKECH'
• '{{name[0]}}' - 'J'
• '{{fn.ucwords('hello world')}}' - 'Hello World'
• '{{fn.urlencode(name)}}' - 'Jakub+Mi%C5%A1kech'

Time data

Scope data:

["strtotimeValue" => "yesterday"]

• '{{fn.date('Y-m-d H:i:s')}}' -> '2020-04-27 17:01:31'
• '{{fn.time()}}' -> '1580140891'
• '{{fn.strtotime(strtotimeValue)}}' -> '1579993200'
• '{{fn.strtodate('yesterday')}}' -> '2020-04-26 00:00:00'
• '{{fn.strtodate('yesterday', 'Y-m-d')}}' -> '2020-01-26'

Number data

Scope data:

["numberA" => "1.4"]

• '{{fn.round(1.5)}}' -> '2'
• '{{fn.round(numberA)}}' -> '1'
• '{{fn.rand(0, 100)}}' -> '41'

Array data

Scope data:

[
	"map" => ["typePK" => "name"],
	"displayName" => "title",
	"values" => [1, 2, 3],
	"forExplode" => "hi,hello",
	"types" => [
		["name" => "php", "title" => "PHP: Hypertext Preprocessor",
		["name" => "pg", "title" => "PostgreSQL"]
	]
]

• '{{fn.implode(', ', values)}}' -> '1, 2, 3, 4'
• '{{values[0]}}' -> '1'
• '{{fn.implode(', ', fn.array_column(statuses, 'title'))}}' -> 'PHP: Hypertext Preprocessor, PostgreSQL'
• '{{fn.explode(',', forExplode)[1]}}' -> 'hello'
• '{{statuses[0]['title']}}' -> 'PHP: Hypertext Preprocessor'
• '{{statuses[1][displayName]}}' -> 'PostgreSQL'
• '{{statuses[1][map.statusesPK]}}' -> 'pg'

Functions

All available function. More in php.net

• Number

  • round, rand, pow, floor, abs

• Date time

  • time, date, gmdate, strtotime, strtodate*

• Array

  • explode, implode, array_column, array_push, array_merge

• String

  • trim, strlen, substr, strpos, strstr, sprintf, ucfirst, ucwords, strtoupper, strtolower, strip_tags, str_replace, urlencode, rawurlencode

Arithmetic operators

Arithmetic operators are used with numeric values to perform common arithmetical operations, such as addition, subtraction, multiplication and division.

Scope data:

["done" => 9, "total" => 100, "float" => "5.4" ]

• '{{1 + 2}}' -> '3'
• '{{1 + 2 * 3}}' -> '7'
• '{{(1 + 2) * 3}}' -> '9'
• '{{(1.2 + 2,4) * float}}' -> '19.44'
• '{{fn.round((done / total)*100, 2)}} %' -> '9 %'

Conditions

Syntax allow use inline condition with using logical and comparison operators.

Scope data:

["success" => true, "ok" => "ok", "notOk" => "not ok" ]

• '{{(success) ? ok : notOk)}}' -> 'ok'
• '{{(! success) ? ok : notOk)}}' -> 'not ok'
• '{{1 && (0 || success) ? ok : notOk)}}' -> 'ok'
• '{{1 > 0 && 1 < 1 ? ok : notOk)}}' -> 'not ok'

Advanced

You can use this syntax to get access to object value. This work only when you use in template one replacing syntax. Value will be stored in onlyOneParamValue attribute.

<?php
$output = \Yakub\SimpleTemplating\Replace::compile(
	'{{types[1]}}',
	[
		"types" => [
			["name" => "php", "title" => "PHP: Hypertext Preprocessor",
			["name" => "pg", "title" => "PostgreSQL"]
		]
	]
);

echo $output; // Output: "" array isn't transformed to string
echo json_encode($output->onlyOneParamValue); // Output: "{"name":"pg","title":"PostgreSQL"}"
