php - htmlspecialchars() 期望参数 1 为字符串，Laravel 中给出的数组

Question

我的 Laravel blade 模板出现了这个错误

htmlspecialchars() expects parameter 1 to be string, array given

我试图在 Blade 模板中将数组转换为字符串。

这是代码

<script>
    var value = {{ $sliderImageDataArray }}.toString()
    window.MedicPressSliderCaptions = value;
</script>

其中 $silderImageDataArray 是存储在这里的变量和值。

这是$silderImageDataArray 值

[{"title":"First title","text":"<p><span id=\"hs_cos_wrapper_module_1498510869515998\" class=\"hs_cos_wrapper hs_cos_wrapper_widget_container hs_cos_wrapper_type_widget_container\" data-hs-cos-general-type=\"widget_container\" data-hs-cos-type=\"widget_container\">First title<\\\/span><\\\/p>\n<p><a class=\"btn  btn-secondary\" href=\"http:\\\/\\\/localhost\\\/sencare\\\/book-appoinment\\\/\" target=\"_self\">  Make An Appointment <\\\/a>\\u00a0<a class=\"btn  btn-light\" href=\"http:\\\/\\\/localhost\\\/sencare\\\/our-doctors\\\/\" target=\"_self\"> Our Doctors<\\\/a><\\\/p>\n","is_video":false},{"title":"Second","text":"<p><span id=\"hs_cos_wrapper_module_1498510869515998\" class=\"hs_cos_wrapper hs_cos_wrapper_widget_container hs_cos_wrapper_type_widget_container\" data-hs-cos-general-type=\"widget_container\" data-hs-cos-type=\"widget_container\">Second<\\\/span><\\\/p>\n<p><a class=\"btn  btn-secondary\" href=\"http:\\\/\\\/localhost\\\/sencare\\\/book-appoinment\\\/\" target=\"_self\">  Make An Appointment <\\\/a>\\u00a0<a class=\"btn  btn-light\" href=\"http:\\\/\\\/localhost\\\/sencare\\\/our-doctors\\\/\" target=\"_self\"> Our Doctors<\\\/a><\\\/p>\n","is_video":false}]

{{}} 将被 Blade 模板引擎转换为 echo()。而您正试图将数组作为字符串回显。

您可以将其转换为 JSON:

var value = '{{ json_encode($sliderImageDataArray) }}';

如果是 Laravel 集合或模型:

var value = '{{ $sliderImageData->toJson() }}';
