| protected _conditions ( array $step, array $params, array $data, array $options ) : boolean | ||
| $step | array | The array of instructions that define a rendering step. |
| $params | array | The parameters associated with this rendering operation, as passed to `render()` (filtered from the `$options` parameter). |
| $data | array | The associative array of template variables passed to `render()`. |
| $options | array | The `$options` parameter, as passed to `render()`. |
| Результат | boolean | Returns `true` if the step should be executed, or `false` if the step should be skipped. If the step array has a `'conditions'` key which is a string, it checks to see if the rendering options (`$options`) contain a key of the same name, and if that key evaluates to `true`. If `'conditions'` is a closure, that closure is executed with the rendering parameters (`$params`, `$data`, and `$options`), and the result is determined by the return value of the closure. If a step definition has no `'conditions'` key, it is always executed. |
