生成和读取条形码 [英] Generating and reading barcode
问题描述
我为一家拥有国家办事处的大公司建立了一个电子购物网站。
I've built an e-shopping website for a big company which has country offices.
我想要做的是以下：
- 在发送包裹到公司国家办公室之前通过PHP生成条形码
- 当商品抵达国家办公室时，工作人员将登录自己的帐户，通过条码阅读器
只有通过网络界面才能实现？我的意思是没有任何本地应用程序。怎么做？ PLease说明。
Is it possible only with web interface? I mean without any local application. How to do that? PLease explain.
推荐答案
所以这里是一个可以为你工作的方法：
so here is an approach that could work for you:
您需要在数据库中添加记录，如：
You need to put a record in a database like:
package_id | name | status
1234 My Package shipped
生成包含package_id的条形码，您必须决定要使用哪种类型的条形码。您还可以使用数据矩阵。然后您创建条形码作为图像，以便您可以打印。数据矩阵非常适合大型自定义数据。
Generate a barcode which contains the package_id, you have to decide what kind of barcode you want to use. You could also use a data matrix. Then you create the bar code as image so that you can print it. Data Matrix is very good for large custom data.

打印条形码，放在包装上
Print the bar code, put it on your package
包裹到达办公室，用户登录到您的网站，点击确认包裹接收或任何。然后有一个文本字段，他聚焦文本字段，扫描条形码/数据矩阵，您的包ID1234将出现在文本字段中
The package arrives at the office, the user logs on to your website, clicks on "Confirm Package Received" or whatever. Then there is a text-field, he focuses the text-field, scans the barcode/data matrix and your package ID "1234" will appear in the text-field
提交表单，在数据库中查找条目，将其更改为：
Submit the form, lookup the entry in the database, change it to:
package_id | name | status
1234 My Package delivered
提示 a QR Code 它可以被许多手机读取，所以你不需要一个真正的酒吧代码扫描器。您可以编写一个读取条形码的应用程序，并将package_id发送到您的服务器。
A Tip If you use a QR Code it can be read by many mobile phones, so you don't need a real bar code scanner. You could write an app that reads the bar code and sends the package_id to your server.
