보라색 부분은 form_action5-1.php파일에서 유효성 확인을 위해 form5-1.php파일에서 자바스크립트 폼 체크 부분을 삭제합니다.
form_action5-1.php파일에서 값을 체크하는데 자바스크립트로 폼체크 하는 부분과 유사합니다.
다만 하늘색 부분은 php에서 자바스크립트 실행 하는 부분입니다.
alert()함수로 메세지를 보내고 페이지 이동을 합니다.
window.location.href='[page]’; 대신에 history.go(-1);을 쓸 수도 있는데 잘못된 곳으로 이동할 가능성이 큽니다.
그래서 window.location.href='[page]’;를 사용하는게 더 효율적입니다.
The purple part deletes the JavaScript form check part from the form5-1.php file to confirm validity in the form_action5-1.php file.
Checking the value in the form_action5-1.php file is similar to checking the form using JavaScript.
However, the light blue part is the part where JavaScript is executed in PHP.
Send a message using the alert() function and move to the page.
window.location.href='[page]’; You could use history.go(-1); instead, but it would most likely take you to the wrong place.
So it is more efficient to use window.location.href='[page]’;
