Understanding AnQiCMS'sRequiredfield

In the AnQiCMS backend, whether it is the 'Content Model' field you customize or the form field of the 'Website Message' function, there will be an option for 'Required'.When you check this option, AnQiCMS will perform strict verification when the data is submitted to the backend to ensure that these fields marked as required are not empty.This is a crucial backend validation mechanism that ensures the integrity of the data you collect.

But it is not enough to do validation only on the backend.A good form should clearly inform the user which fields are required before submission and provide immediate feedback.requiredThe attribute is born for this.It allows the browser to prompt for required fields that have not been filled in on the client side, greatly enhancing the user experience.RequiredThe status is seamlessly passed to the front-end template, allowing us to easily achieve this goal.

Assuming your message form template code snippet is as follows:

<form method="post" action="/guestbook.html">
{% guestbook fields %}
    {% for item in fields %}
    <div>
        <label>{{item.Name}}</label>
        <div>
            {% if item.Type == "text" or item.Type == "number" %}
            <input type="{{item.Type}}" name="{{item.FieldName}}" {% if item.Required %}required{% endif %} placeholder="{{item.Content}}" autocomplete="off">
            {% elif item.Type == "textarea" %}
            <textarea name="{{item.FieldName}}" {% if item.Required %}required{% endif %} placeholder="{{item.Content}}" rows="5"></textarea>
            {% elif item.Type == "radio" %}
            {%- for val in item.Items %}
            <input type="{{item.Type}}" name="{{item.FieldName}}" value="{{val}}" title="{{val}}" {% if item.Required %}required{% endif %}>
            {%- endfor %}
            {% elif item.Type == "checkbox" %}
            {%- for val in item.Items %}
            <input type="{{item.Type}}" name="{{item.FieldName}}[]" value="{{val}}" title="{{val}}" {% if item.Required %}required{% endif %}>
            {%- endfor %}
            {% elif item.Type == "select" %}
            <select name="{{item.FieldName}}" {% if item.Required %}required{% endif %}>
                {%- for val in item.Items %}
                <option value="{{val}}">{{val}}</option>
                {%- endfor %}
            </select>
            {% endif %}
        </div>
    </div>
    {% endfor %}
    <div>
        <div>
            <button type="submit">提交留言</button>
            <button type="reset">重置</button>
        </div>
    </div>
</form>

In this code, the core logic is体现在{% if item.Required %}required{% endif %}on this line. Whenitem.RequiredThe value istrue(i.e., the background configuration is required), the template engine will render the HTML ofrequiredProperty.This, the browser will automatically recognize these fields as required when rendering the form, and will display the native error prompt to guide the user to complete the filling when the user tries to submit an empty value.

• Ensure data quality:Enforce users to fill in key information, ensuring the completeness and accuracy of the data required for business processes, and reducing the cost of data processing later.
• Simplify development and maintenance:Developers only need to check 'Is Required' in the AnQiCMS backend, and the front-end template will automatically respond without manually adding it to each input boxrequiredProperty, reduces repetitive work and avoids inconsistencies between front-end and back-end rules.
