Laravel使用JSON生成表单

// 定义JSON表单结构
$json = '
{
    "fields": [
        {
            "name": "name",
            "type": "text",
            "label": "Name",
            "required": true
        },
        {
            "name": "email",
            "type": "email",
            "label": "Email",
            "required": true
        },
        {
            "name": "gender",
            "type": "select",
            "label": "Gender",
            "options": [
                {"value": "male", "label": "Male"},
                {"value": "female", "label": "Female"}
            ]
        },
        {
            "name": "agree",
            "type": "checkbox",
            "label": "Agree to terms"
        }
    ]
}';

// 解析JSON
$data = json_decode($json, true);

// 生成表单
$form = '';
foreach ($data['fields'] as $field) {
    switch ($field['type']) {
        case 'text':
            $form .= Form::label($field['name'], $field['label']);
            $form .= Form::text($field['name']);
            break;
        case 'email':
            $form .= Form::label($field['name'], $field['label']);
            $form .= Form::email($field['name']);
            break;
        case 'select':
            $form .= Form::label($field['name'], $field['label']);
            $form .= Form::select($field['name'], $field['options']);
            break;
        case 'checkbox':
            $form .= Form::label($field['name'], $field['label']);
            $form .= Form::checkbox($field['name']);
            break;
    }
}

// 渲染表单
return view('form', ['form' => $form]);
