Echo a response in other php file

[djburner]

Hi there, I have a little html form in a page called "yourbirthday.html" (including username and password). Then in this form I use "insert_bd.php" to handle the info.

<form action="insert_bd.php" method="post" />

<table style="padding:125px 10px 10px 10px; color:white; width: 240px;" border="0" align="center">
<tr>
   <td>Username</td>
    <td><input type="text" name="username" maxlength="30" size="13" value="username" /></td>
</tr>
<tr>
   <td style="color:white;">Password</td>
    <td><input type="password" name="password" maxlength="30" size="13" /></td>
</tr>

Since in my insert_bd.php I have only code if you dont input a username or a password a message will be echo telling you that there is something missing, but I dont want that message to be echoed in insert_bd.php but in yourbirthday.html where the form is nested and the user can know what is missing a change it.

This is the code in insert_bd.php, I wrote this code which is not doing what I want but it can illustrate it.

$myusername=$_POST['username'];
$mypassword=$_POST['password'];


if(empty($_POST['username']))
{
   header("location: http://myweb.com/yourbirthday.html");
   $error = 'No username'; // I need this print or echoed in yourbirthday.html
   exit;
}elseif(empty($_POST['password'])){
   header("location: http://myweb.com/yourbirthday.html");
   $error = 'No Password'; // I need this print or echoed in yourbirthday.html
   exit;
}

How can I do this or what is the commo practice on something like this?
Thanks for any information or approach on this one.
Greetings.

I would say the "common" practice IMHO is to not do a redirect at all - simply re-display the form with the included error message.

Hi bradgrafelman, yes, It sounds that is the way, but I dont have much of a clue how to do it.

How can I re-display the error message in yourbirthday.html after of been processed by the funtion on insert_bd.php?

Thanks for your time and help.
Greetings.

Combine both files into one. Call it yourbirthday.php and put the PHP at the top of the file. Add in a check to see if the form has been submitted. If it has, process it. Otherwise just display it as if a user just navigated to the page.

the benefit of putting it in one file as bonesnap suggests, is that A this falls under being the more common practice, and B it will allow you to not just display the error message, but also prefill fields with information that wasn't ommitted.
