填充文本提交的值或占位符laravel

Question

我想从数据库填充文本字段的值，如果它不等于默认列值。 $event_date的默认列值为'0000-00-00 00:00:00'。

如果$event_date='0000-00-00 00:00:00'话，我想用占位符Date

@if($conversation->event_date!='0000-00-00 00:00:00') 
    <div class="form-group"> 
    {{ Form::text('event_date', null, array('class' => 'form-control 
    conversation-field')) }} 
    </div> 
@else 
    <div class="form-group"> 
    {{ Form::text('event_date', null, array('class' => 'form-control 
    conversation-field','placeholder'=>'Date')) }} 
    </div> 
@endif 

Answer 1

输出HTML内容时，所以{你不应该逃避！而不是{{

@if ($conversation->event_date != '0000-00-00 00:00:00') 
    <div class="form-group"> 
    {!! Form::text('event_date', $conversation->event_date, array('class' => 'form-control 
    conversation-field')) !!} 
    </div> 
@else 
    <div class="form-group"> 
    {!! Form::text('event_date', null, array('class' => 'form-control 
    conversation-field','placeholder'=>'Date')) !!} 
    </div> 
@endif

在你会做这样的事情一个简单而整洁的方式：

<div class="form-group"> 
    {{ Form::text('event_date', $conversation->event_date != '0000-00-00 00:00:00' ? $conversation->event_date : null, array('class' => 'form-control 
    conversation-field', 'placeholder'=>'Date')) }} 
    </div>
