How to pass a custom function to a Laravel Blade template?
提问by wobsoriano
I have a custom function and I want to pass it in a blade template. Here is the function:
我有一个自定义函数，我想在刀片模板中传递它。这是函数：
function trim_characters( $text, $length = 45, $append = '…' ) {
$length = (int) $length;
$text = trim( strip_tags( $text ) );
if ( strlen( $text ) > $length ) {
$text = substr( $text, 0, $length + 1 );
$words = preg_split( "/[\s]| /", $text, -1, PREG_SPLIT_NO_EMPTY );
preg_match( "/[\s]| /", $text, $lastchar, 0, $length );
if ( empty( $lastchar ) )
array_pop( $words );
$text = implode( ' ', $words ) . $append;
}
return $text;
}
And the usage is like this:
用法是这样的：
$string = "A VERY VERY LONG TEXT";
trim_characters( $string );
Is it possible to pass a custom function to the blade template? Thank you.

You don't have to passanything to blade. If you define your function, you can use it from blade.
您不必将任何东西传递给刀片。如果你定义了你的函数，你可以从blade中使用它。
- Create a new
app/helpers.phpfile. - Add your
trim_charactersfunction to it. - Add that file to your
composer.jsonfile. - Run
composer dump-autoload.
- 创建一个新
app/helpers.php文件。 - 将您的
trim_characters功能添加到其中。 - 将该文件添加到您的
composer.json文件中。 - 运行
composer dump-autoload。
Now just use the function directly in blade:
现在直接在blade中使用该函数：
{{ trim_characters($string) }}
