want to show a message on the same (form) page.

[nadeem14375]

Dear all,

 

I have signup form, on clicking the submit button, the control goes to "process.php". where i check the form's required fields are filled or not, if not filled it come back to signup.php and show the message. "Please fill all the required fields".

 

1. Is this right way to do it?

2. I want to show the message bellow the submit button, but couldn't succeed.

Could just process the form on the same page, or set a session variable and when you return back to the signup page display the error.

If you want to check it on the same page, you point your form to $_SERVER['PHP_SELF'] or manually put in the page's name (you can even leave it blank) and check if the form was submitted with something like:

if(isset($_POST) && !empty($_POST)){
... do form checking here, set error if necessary, or redirect to some other page
}else{
just show form and error if it was set.
}

 

alternatively, you can just include the form-checking script if $_POST is not empty.

 

hope this helps

You may want to use ajax for you site? I used ajax for my site to check for the data

You want to use also $_SERVER['SCRIPT_NAME'] instead of $_SERVER['PHP_SELF'], since PHP_SELF has XSS security holes used just plain like that.

and even better:

<form action="" method="post">                         <!-- no action indicates: same script    -->

Yeah thats true for all the mainstream browsers, but might not work on all browsers like some cuztomized browsers on some mobile platforms.
