html - PHP Form Post/Redirect/Get Header Location Error -
i have simple form i've made me learn php. i'm using local host server host php file (form.php). however, when refresh page resubmits form, know can use post/redirect/get method negate problem. except implementing header('location: form.php'); hasn't been working, if take @ code- , tell me i'm doing wrong, appreciated.
code example i.e without header('location: form.php');
<?php if (empty($_post) === false) { echo '<pre>', print_r($_post, true), '</pre>'; } ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>form</title> </head> <body> <form action="form.php" method="post"> <p> <label for="name">name:</label><br> <input type="text" name="name" id="name"><br> </p> <p> <label for="email">email:</label><br> <input type="text" name="email" id="email"><br> </p> <p> <label for="message">message:</label><br> <textarea name="message" id="message"></textarea> </p> <p> <input type="submit" value="submit"> </p> </form> this result...
screen shot without header location
then add:
header('location: form.php'); and this...
to prevent form resubmitting on page refresh, 2 methods used:
method 1: use ajax + redirect
submit form using ajax , redirect page using jquery.
method 2: reload page
refresh page using javascript.
your code should this:
<?php if (!empty($_post)) { echo '<pre>', print_r($_post, true), '</pre>'; echo '<script type="text/javascript"> location.reload();</script>'; } ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>form</title> </head> <body> <form action="form.php" method="post"> <p> <label for="name">name:</label><br> <input type="text" name="name" id="name"><br> </p> <p> <label for="email">email:</label><br> <input type="text" name="email" id="email"><br> </p> <p> <label for="message">message:</label><br> <textarea name="message" id="message"></textarea> </p> <p> <input type="submit" value="submit"> </p> </form> </body> </html>
