Output iteration in textarea

[christiangarsia]

Possibly I'm completely missing something, but I can't figure out how to iterate over an array and output that list within a text area followed by "\r\n" after each value.

eg. ["foo", "bar"] would output as

<textarea> foo \r\n bar \r\n </textarea>

I think this is largely a limitation stemming from HTML. All HTML <input> types take a single value attribute, including the textarea type. So I don't think there is any way that Transphporm can easily append a new string to the previous iteration's string without a lot of new grammar being added. Not impossible, but difficult and perhaps undesirable for such a single special case.

I made a transphporm extension for calling native php functions on data in the tss which could be used to implode an array. I can share the simple extension I made if you wish.

This extension seems like a feature that I'd like to use. Please provide an example of how to use it.

Thanks for the tip. I’d love to know how to use that extension you made.

class PhpFunc implements \Transphporm\TSSFunction {
    public function run(array $args, \DomElement $element) {
        return call_user_func(...$args);
    }
}
class PhpModule implements \Transphporm\Module {
    public function load(\Transphporm\Config $config) {
        $functionSet = $config->getFunctionSet();
        $functionSet->addFunction('php', new PhpFunc());
    }
}

Above is the classes needed. I have them in a namespace in my actual code and removed some extra stuff I add with the module. Just load the module through the loadModule method.

Example basic use case

<?php
require "vendor/autoload.php";

$xml = '<span></span>';

$tss = "span  { content: php('implode', ', ', data()); } ";

$data = ['A', 'B', 'C'];

$template = new Transphporm\Builder($xml, $tss);
echo $template->output($data)->body . PHP_EOL;

would return

<span>A,B,C</span>

The function when used in transphporm takes the php function name to call as the first argument and then the following arguments are what is passed to the function being called.
