如何删除视图中的空格?
How can I remove spaces in view?
我用laravel 5.3
我的情况是这样的:
我的代码在视图中:
<div class="alert alert-warning" role="alert">
"
@if(isset($country))
{{ $country }}
@endif
@if(isset($city))
@if(isset($country))
-
@endif
{{ $city }}
@endif
"
</div>
结果是这样的:
" England - London "
我想要这样的结果:
"England - London"
我该怎么做?
您试过使用PHP的trim功能吗?
http://php.net/manual/en/function.trim.php
<div class="alert alert-warning" role="alert">
<span>"</span>
@if(isset($country))
{{ $country }}
@endif
@if(isset($city))
@if(isset($country))
-
@endif
{{ $city }}
@endif
<span>"</span>
</div>
这不是最好的方法,但您可以尝试将字符串设置为变量并尝试以下代码。请验证控制器中的变量是否不包含空格,并将修剪后的变量发送到视图
<div class="alert alert-warning" role="alert">
{{--*/ $finalString = ""; /*--}}
@if(isset($country))
{{--*/ $finalstring .= $country; /*--}}
@endif
@if(isset($city))
@if(isset($country))
{{--*/ $finalString .= ' - '; /*--}}
@endif
{{--*/ $finalString .= $city; /*--}}
@endif
"{{ $finalString }}"
</div>
您可以使用:
@isset($country)
@php($result = $country)
@endisset
@isset($city)
@isset($country)
@php($result .= '-')
@endisset
@php($result .= $city)
@endisset
{{$result}}
祝你好运!
