bad pattern on regexp

[lorinczelod]

Hello
the test case:
Tabular Input with kartik-v/yii2-widget-fileinput:

<?= TabularInput::widget([
    'allowEmptyList' => true,
    'models' => $models,
    'attributeOptions' => [
        // ...
    ],
    'columns' => [
        // ...
        [
            'name'  => 'imageFile',
            'title' => 'imageFile',
            'type'  => FileInput::className(),
            'options' => [
                'options' => ['accept' => 'image/*'],
                'pluginEvents' => [
                    'filecleared' => 'function () {
                            console.log('File cleared!);
            }',
                ],
            ],
        ],
    ],
]) ?>

this code generates the next javascript:

jQuery('#item-{multiple-index}-imagefile').fileinput(fileinput_84f9f1b5);
jQuery('#item-{multiple-index}-imagefile').on('filecleared', function () {
    console.log('File cleared');
});

this js code isn't found by this 'if' in BaseRenderer.php:

if (preg_match('/^[^{]+{multiple-index}.*$/', $js) === 1) {

I recommend the m (PCRE_MULTILINE) regexp modifier:

if (preg_match('/^[^{]+{multiple-index}.*$/m', $js) === 1) {

This working for me.

Sincerely, E.
