请问php生成条形码再取数据的流程是怎样的
我想在条形码扫描器扫后显示一个学生的详细信息
我的设想是，在数据库中添加一个条形码字段，在添加学生的时候每一次都生成一个9位数字的随机不重复条形码与学生信息一起添加到数据库，然后当扫描器扫描时，将条形码数字放入text进行sql搜索(听说扫描器和键盘输入一样？)，从数据库搜索到条形码数字 得到同行学生信息再进行显示。
请问这样可行吗？有没有什么更好的方法？
回复讨论(解决方案)
生成二维码用JavaScript就行，扫描器和键盘输入差不多吧，光标在输入框扫描的时候会自动将信息填入输入框中
javascript生成二维码
jquery绘制条形码
用用户id作为条形码内容，扫描后获取用户id再调用api获取用户资料。
条形码生成看楼上的例子。
条形码内容用学号就行了，不用另外添加字段
