我怎么能放一个Html<form> PHP 函数中的标记，这会将我重定向到另一个 .php 文件？

Question

I have been searching for hours on the web and I just can't seem to find an answer.

What I want to do is put a <form> tag inside a php function which would redirect me to another x.php file if a certain criteria is met.

Answer 1

Sounds simple enough:

function myFunction() {
    if ( Some Condition Here ) {
        ?>
             <form action="x.php">
                 <button>submit</button>
             </form>
        <?php
    }
}

Obviously the "redirect" won't happen until the form is submitted. Redirecting is done in response to an HTTP request not to "having a form".

Answer 2

You don't use form to redirect , you use a header

function redirect(url){
  header("Location: ".url);
  die();
}

so now

if(some_condition){
  redirect("anotherFile.php");
}

Answer 3

For redirect use following code:

header('Location: page.php');
exit;
