What information? From what web page? Save it where?

You can.
I try to send the information from a text box and I want to save this string , after that I want to read the information from the SD on the web page with a button.
Posting the code that is running on the Arduino would be a start. Explaining what parts of what you want to do are not working would be good.
What information? From what web page? Save it where?
the information from textbox on the html web and save on the SD card . I want to read the information from the SD on the web page with the READTEXT button.
Thanks for your comments.
//client.write(myFile.read()); // I do not know why this line not works
client is a variable local to loop(). If you want to use the client variable, you must either pass that as a parameter in the function call, or declare client as global.
Stay away from the String data type. It is unreliable and prone to crashing. Use character arrays instead.
