Get the name value passed by the image button in php_PHP tutorial

I need to use image buttons to beautify my web, but using the connection transfer method will cause variable values ​​to appear in the browser bar, which looks uncomfortable. If I use hidden to submit, I don’t think it is necessary, because since the image has the name attribute , it should be able to be obtained, why do we need to add an extra variable? I posted it on bbs for several days and no one answered, so I had to read books and find a solution, and then I found it!

If the image in the form is used as submit, two related variables will be generated, for example:

Then, During the submission process, two variables will be generated, aaa_x and aaa_y
which contains the specific position x and y of the image on the screen
Then in php, just judge aaa_x and aaa_y

No need for any hidden fields, javascript, and connection value passing behavior!

The test passed. Everyone is welcome to test. If you have any questions, please contact me!
