As an experienced website operations expert, I know that every detail in a content management system can affect the overall performance of a website, whether it is user experience or search engine optimization (SEO).

Security CMS QR code imagealtCustomize the text attribute: insights into features and practical strategies

In modern website operations, QR codes are widely used as a convenient means of communication or content distribution tool in all corners.AnQi CMS is an efficient and customizable content management system, which naturally also provides a convenient QR code output function.联系方式标签When calling the QR code image set in the background, many operators will be concerned about a question: whether this image can have custom like other imagesaltText attribute to enhance SEO effect and accessibility experience?

To answer this question, we need to explore both the template mechanism and contact information settings of the Anqi CMS.

剖析Qrcode标签的运作方式

安全CMS的模板设计借鉴了Django模板引擎的语法，这种灵活性是其一大亮点。在tag-contact.mdIn the document, we can see联系方式标签的使用方法，其中QrcodeThis field is specifically used to output a WeChat QR code (or other general QR code). Its basic calling method is like this:

{# 默认用法 #}
<li>
    <span>微信二维码</span>
    <span>
        <img src="{% contact with name="Qrcode" %}" />
    </span>
</li>

From this code, we can see that,{% contact with name="Qrcode" %}The main responsibility of this tag isReturns the URL of the QR code image. It does not generate a complete one directly<img>a tag, but embeds its URL assrcthe value of the property into the one you manually write<img>Label inside. This is the key to its flexibility.

This means, althoughQrcodeThe tag itself does not provide a directaltattribute parameter, but since you can fully control it in the template<img>The structure of the label, so it addsaltThe text is perfectly feasible.

Smartly customizealtText properties

SinceQrcodeIf the tag only provides the image URL, then customizealtText becomes a template-level operation. The security CMS backend contact information settings provide a "Custom Settings Parameters" feature, which is the tool we use to solve this problem.

1. Add custom parameters in the background:First, log in to your security CMS backend, navigate to:后台设置-联系方式设置(such ashelp-setting-contact.mdas described).You will see default contact, phone, address, and other fields, as well as an 'Custom settings parameters' area.altText field.

   • Parameter name:We can name it:QrcodeAltText(Used when calling the template).
   • Parameter value:Enter the text you want to appear on the QR codealtThe specific content of the text, for example: 'Follow AnQi CMS official WeChat account to get the latest information.'
   • Note:Can write

2. Call in the front-end template:Complete the background settings and save, and then you can call this custom parameter in the frontend template files of the website (usuallybash.html/footer.htmlor a specific page template).

   CombineQrcodeThe label output image URL and theQrcodeAltTextcustom parameters, you can construct the whole<img>Tags:

   <li>
       <span>微信二维码</span>
       <span>
           <img src="{% contact with name="Qrcode" %}" alt="{% contact with name="QrcodeAltText" %}" />
       </span>
   </li>
   

   In this way,srcThe value of the attribute comes fromQrcodeThe label provided image URL, andaltThe value of the property comes from your custom definitionQrcodeAltTextParameters. This way, the QR code image has rich semantics.altText that can help search engines understand the content of the image and provide valuable information to users who use screen readers.
