2 pages. 1 html. 1 php

Hoangsta

I have a form page and another page that does the action of the form page. Right now, my echo statements are always showing up top, and I do not want that. I want to be able to put the echo in a desired spot.

My code from html (join_form.html) page:

<form name="form1" method="post" action="register.php">
///Form data: firstname, lastname, etc////////////////
</form>

My code form the php (register.php) page:

<?
if((!$first_name) || (!$last_name) || (!$email_address) || (!$username)){
echo 'You did not submit the following required information! <br />';
if(!$first_name){
echo "First Name is a required field. Please enter it below.<br />";
}
if(!$last_name){
echo "Last Name is a required field. Please enter it below.<br />";
}
if(!$email_address){
echo "Email Address is a required field. Please enter it below.<br />";
}
if(!$username){
echo "Desired Username is a required field. Please enter it below.<br />";
}
include 'join_form.html'; // Show the form again!
/ End the error checking and if everything is ok, we'll move on to
creating the user account /
exit(); // if the error checking has failed, we'll exit the script!
}

?

all of my echos are showing on top....I want them to appear near the form itself...stating the error (echo) and showing the form underneath it. As of right now...my echos are on top while my form is in the middle of my page.

What I mean by "my echos are on top" I meant, it's showing above my navigations, logo, etc.

should I have both .html (join_form) and php (register.php) migrate to one single .php form and have the action (register.php) be rename to <?=$PHP_SELF?>

<form action="<?=$PHP_SELF?>" method="post">

took a while until I got what you want (I hope I do).

It's not a good thing to include a complete html page since you would have the html, header and body tags displaced or doubled. Most browsers cope with this, but you shouldn't rely on them.

So I really think it may be a good idea to integrate the form into the script right away. As an additional benefit, you can more easily save the visitors from retyping all the entries that were correct which is most annoying.

Rather than echoing the message straight away, I usually put it into a variable, so then I can echo it whenever the hell i please 🙂

for example:

// if the form has been submitted
if(isset($_POST['submit'])) {

/* This checks the length of the input (the trim function clears
any leading or trailing spaces so that the user can't just put in
a space */

if(strlen(trim($_POST['username'])) == 0) {

	$ErrorMsg = "<span style=\"color: red;\">You didn't provide a username!</span>";
}

// Put all your other stuff here

echo "<form>";
// The variable is appended to the form output, if there's no error, it wont echo anything
echo "<input type=\"text\" name=\"username\">&nbsp;$ErrorMsg";
echo "</form>";

// And a bunch of more stuff here
} else {

// Display your original form, or redirect back to your other form, etc.
}

Hope that helps!

btw, you can still do this if you're using $PHP_SELF as an action.

what xblue is telling me that I would take my html (join_form.html) and php (register.php) and integrate into one. Meaning, from my php page, also attached the codes from my join_form.html and call it something else. Let's say we call it join.php. Anyways, i'm not good at explaining this conflict that I have. Here is the code:

join_form.html

All of my header info.....then my form.

<form name="form1" method="post" action="register.php">
<table width="100%" border="0" cellpadding="4" cellspacing="0">

<tr>
<td height="26" colspan="2" valign="top"><div align="center"><font face="Verdana, Arial, Helvetica, sans-serif"><strong>Member
Account Information</strong></font></div></td>
</tr>
<tr>
<td height="27" colspan="2" valign="top"><font face="Verdana, Arial, Helvetica, sans-serif"> </font></td>
</tr>
<tr>
<td width="294" height="30" align="left" valign="top"><div align="right"><font size="2" face="Verdana, Arial, Helvetica, sans-serif">First
Name</font></div></td>
<td width="388" valign="top">  <input name="first_name" type="text" id="first_name" value="<? echo $first_name; ?>"></td>
</tr>
<tr>
<td height="30" align="left" valign="top"><div align="right"><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Last
Name</font></div></td>
<td valign="top">  <input name="last_name" type="text" id="last_name" value="<? echo $last_name; ?>"></td>
</tr>
<tr>
<td height="30" align="left" valign="top"><div align="right"><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Email
Address</font></div></td>
<td valign="top">  <input name="email_address" type="text" id="email_address" value="<? echo $email_address; ?>"></td>
</tr>
<tr>
<td height="30" align="left" valign="top"><div align="right"><font size="2" face="Verdana, Arial, Helvetica, sans-serif">Desired
Username</font></div></td>
<td valign="top">  <input name="username" type="text" id="username" value="<? echo $username; ?>"></td>
</tr>
<tr>
<td height="32"></td>
<td valign="top">  <input type="submit" name="Submit" value="Join Now!"></td>

    </table>
  </form>

end of my form and include my footer

//////////////////////////////////
register.php page
//////////////////////////////
<?

include 'db.php';

// Define post fields into simple variables
$first_name = $POST['first_name'];
$last_name = $POST['last_name'];
$email_address = $POST['email_address'];
$username = $POST['username'];

/ Let's strip some slashes in case the user entered
any escaped characters. /

$first_name = stripslashes($first_name);
$last_name = stripslashes($last_name);
$email_address = stripslashes($email_address);
$username = stripslashes($username);

/ Do some error checking on the form posted fields /

if((!$first_name) || (!$last_name) || (!$email_address) || (!$username)){
echo 'You did not submit the following required information! <br />';
if(!$first_name){
echo "First Name is a required field. Please enter it below.<br />";
}
if(!$last_name){
echo "Last Name is a required field. Please enter it below.<br />";
}
if(!$email_address){
echo "Email Address is a required field. Please enter it below.<br />";
}
if(!$username){
echo "Desired Username is a required field. Please enter it below.<br />";
}
// show_form();
include 'join_form.html'; // Show the form again!
/ End the error checking and if everything is ok, we'll move on to
creating the user account /
exit(); // if the error checking has failed, we'll exit the script!
}

Your telling me to open up my register.php and include my header, <form></form>and footer of my join_form.html?

matt_4013, I'm totally not to much of a professional with php. I was looking at your example, and I got lost.

// Put all your other stuff here

what should i put?

echo "<form>";

if my form name is "form1" should i

echo "<form1>";
echo "</form1>";

also,

// And a bunch of more stuff here
} else {

// Display your original form, or redirect back to your other form, etc.
}

....

A small example
<!-- Your Javascript goes here
..>
<form>
<input type="text" name="Name" value=$Name ID=$Name><? print $err_msg ?>
.............................
</form>
#after submit
if (!$name)
{
$err_msg = "Name is empty";
}
Think this shud work

Hoangsta, please use the [php] tags to enable syntax highlighting when you post code, it is easier to read then.

to integrate your form you need to get the logic right, could be something like
[pre]
- display your header information

if form has been submitted (e.g. check if $_POST['submit'] exists)
check for errors
if submit isn't set or an error occurred
display form
else
do whatever, confirmation message or something
display footer

[/SIZE][/pre]
Hope this is making sense to you.

matt_4013 illustrated xblue's idea rather clearly. Just follow matt's example, and you will get there.

The logic is this: the page has two portion of scripts: the top for processing data, and the bottom for getting data. The processing portion will be executed only when data are submitted. When a user comes to this page, no submission is made, so he will be presented the submission form. When he presses the submit button, because the action=$PHP_SELF (the same file), the file will run again only this time it detects there has been a submission, and hence the top portion script will be executed. If you have some sort of check like matt did, it will comb through the data. When some data are not entered or not in the write format, an error message will apprear, and the form will also appear with data already entered. When it passes the check, it will register the user by inserting data into database and do other things you want it to do.
