php - 将数据库中的值添加到预填写表单中

Question

这个问题已经有答案了:

PHP parse/syntax errors; and how to solve them (20 个回答)

已关闭 5 年前。

{{Form::label('listing', 'Price:')}}
{{Form::text('price','' , ['class' => 'form-control', 'placeholder' => 'Price'])}}

我想在表单中预先填写值 {{listing->price}}来自数据库

{{Form::label('listing', 'Price:')}}
{{Form::text('price','{{listing->price}}' , ['class' => 'form-control', 'placeholder' => 'Price'])}}

ERROR: Parse error: syntax error, unexpected '}', expecting ',' or ')'

这是一个好的解决方案吗？设置变量并解析它

$f = ($listing->price);
echo('{{Form::text('price',.$f. , ['class' => 'form-control', 'placeholder' => 'Price'])}}')

转义你的引号:

    echo '{{Form::text(\'price\','.$f.' , [\'class\' => \'form-control\', \'placeholder\' => \'Price\'])}}';
