我无法使用\\ Template :: instance（）-> render打开文件。 我收到以下错误

Question

It is giving me the following error,

[text] => Unable to open /home/mehul/www/portal.hsua.com.au/public_html/assets/templates.html

This is the part of code which is causing the problem.

    $this->f3->set('const', $constants);
    ob_start();
    echo \Template::instance()->render('/home/mehul/www/portal.hsua.com.au/public_html/assets/templates.html');
    $renderedView = ob_get_clean();

    /*foreach ($variables as $varname => $variable) {
        $this->f3->clear($varname);
    }*/

    return $renderedView;

Answer 1

1. The file might not exist

2. you're opening the PHP file in your webbrowser PHP file is somewhere located in /var/www delivered by Nginx / Apache. If that's the case, your webserver probably has no access to open a file within your home directory.

I recommend you put the template files next to your PHP file to make sure your webserver has access to it.

Answer 2

The render() methods concatenates the given template $file with all template paths stored in the UI system variable while searching for a valid file. Therefore you either have to specify a relative path or append / as workaround.

Workaround

$f3 = Base::instance();
$f3->concat('UI', ';/');

Source/Reference

The concatination $dir.$file in base.php#L2791 is the culprit. Your error is generated a few lines below.

Update / Example

$f3 = Base::instance();
$f3->concat('UI', ';/'); // Add support for absolute paths.

echo \Template::instance()
    ->render(__DIR__ . '/template.html');
