how to use php and volt parameter together?-CodePudding

I am using Volt and PHP in phalcon volt partial

I want to iterate a loop and in the loop I have php code that accept a parameter

this is my code

{% for header in headers %}
<th>
    <?=gettext( {{header}} );?>
</th>
{% endfor %}

here header is a parameter that is used in php code

but I get this error

what is the right way to rewrite this code

CodePudding user response：

Reading documentation shows that echo command is using {{ }} instead of normal PHP tag <?= ?>:

{% for header in headers %}
<th>
    {{ gettext(header) }}
</th>
{% endfor %}

I'm guessing you are trying to use a raw PHP function here, so correct me if I'm wrong. Unfortunately I forget the exact reason this is (I learned a long time), but you have to manually register PHP functions in the Volt Engine in order to use them. This can be done using the addFunction method of the Engine will allow you to add them. I thought it had been resolved that this wasn't needed anymore, but it was reported in https://github.com/phalcon/cphalcon/pull/12841.

Anyways, using addFunction: I've used the below to get around this:

foreach (get_defined_functions()['Internal'] as $functionName) {
    $voltEngine->addFunction($functionName, $functionName);
}

You have to put this in the code that initializes the volt engine.
