Get the name value passed by the image button in php
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 think it is unnecessary, because since the image has a name The attribute should be accessible, so why add an extra variable? I posted it on bbs for several days and no one answered, so I had to read the book and think of 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, two related variables will be generated during the submission process. variables, which are aaa_x and aaa_y
It contains the specific position x and y of the picture on the screen
Then in php just judge aaa_x and aaa_y
No need for any hidden fields, javascript, and connection values Behavior!
The test passed, everyone is welcome to test
