For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

email with required fields

Posted by bschultz (bschultz), 1 October 2004

I'm having a problem getting this to work. Here's the php code:

Code:

<?php
if ((!$name) || (!$address) || (!$city) || (!$state) || (!$country) || (!$email) || (!$RadioGroup1) || (!$RadioGroup2) || (!$RadioGroup3) || (!$question))
{

Print "You forgot something. Please use your back buton!";

} else {

$mailto = "me@myaddress.com";
$msgSubject = "my subject here";
$msgBody = "
Name: $name\n
Address: $address\n
City: $city\n
State: $state\n
Country: $country\n

Computer Type?: $RadioGroup1\n

Connect Speed?: $RadioGroup2\n

Computer Knowledge?: $RadioGroup3\n

Question: $question";

mail($mailto, $msgSubject, $msgBody, "From: $email");

}

?>

Even if every field is filled, I still get the error message to echo. Can someone give me a shove in the right direction? Thanks.

a) Do you still get the problem if you reduce the fields in the test to just one or two? First thing I would do is to experiment with reducing the test and seeing if the problem remains or goes away as a further clue.

b) How are the variables set up? If they're coming from a form, have you recently switched to a newer version of PHP with register_globals set off?

c) in ANY case, modify your message / check system so that it tells the user WHICH field(s) are wrong ... it will help them know how to correct the form and it will tell you more about the problem during development

Hi, Brian ... I've got back and been having a play ... written a little demo (I needed one anyway) to show how I would tackle an application like yours. Try it out at http://www.wellho.net/demo/niceform.php4

Code:

<?php

$fields = array (youremail => "Your email address",
youraddress => "Your Street address",
city => "Your city, state/country zipcode/postcode",
name => "Your name",
what => "Your comment ...");

$aok = 1;

if ($_SERVER[REQUEST_METHOD] == "GET") {
$oopsmsg = "";
$form = "Please complete this form<br>";
} else {
$oopsmsg = "<BR>INFORMATION NEEDED";
$form = "PLEASE PROVIDE ALL FIELDS ... you missed some!<br>";
}

$form .= "<form method=post><table border=1>";
$email = "";
foreach (array_keys($fields) as $f) {
if ($_POST[$f] != "") {
$oopsie = "";
$email .= "$f : $_POST[$f]\n";
} else {
$oopsie = $oopsmsg;
$aok = 0;
}
$form .= "<tr><td>$fields[$f] $oopsie</td>";
$form .= "<td><input name=$f value='".htmlspecialchars($_POST[$f])."'></td></tr>";
}
$form .= "<tr><td> </td><td><input type=submit></td></tr></table></form>";

if ($aok == 1) {
mail ("graham@wellho.net","Form Demo",$email);
$form = "The information you entered has been emailed. Please follow ";
$form .= "<a href=/>this link</a> to return to our home page<br>";
}
?>
<html>
<head><title>Demonstration - form to email</title></head>
<body>
<h1>This is a form to email demo in PHP.</h1>
<?php print $form;?>
<hr>On this demo, all fields must be complete<br>
Copyright, Well House Consultants, <?php print (date("Y")); ?>
</body>
</html>

Sorry I haven't posted back sooner...I've been out of town. I eliminated all but one of the fields...and I still get the same error / results. It still echo's the error message.

The variables are coming in on a form. Here's the code:

Code:

<form method="post" action="web_feedback3.php">

<br>
State:
<input name="state" type="text" id="state" />
<br>
Country:
<input name="country" type="text" id="country" />
<br>

I'll edit your sample code to suit my needs, and I'll post back tomorrow.

Thanks.

Thanks Graham,

I got your code to work, but I had radio buttons in my original form. How can I get those to work in your code. Would I need a second array just for the three radio button categories like I had here:

http://kkbjam.com/pages.php?page=listen.php

Thanks again, Graham.

Brian

Posted by admin (Graham Ellis), 3 October 2004

Nah - I wouldn't bother with another array - simply code something into the existing array that flags a different type of input. I did an example of this with a "select" ... I know very well you do radio programs so wanted radio buttons

but I was having a senior moment ... anyhow, I'm sure you can adapt / adopt.

New demo at: http://www.wellho.net/demo/veryniceform.php4

Code changes: Initial array setup now reads:

Code:

$fields = array (youremail => "Your email address",
youraddress => "Your Street address",
city => "Your city, state/country zipcode/postcode",
name => "Your name",
agegroup => "Age Group|under 21|21 to 39|40 to 64|65 and over",
what => "Your comment ...");

and interpretaion of it is expanded:

Code:

foreach (array_keys($fields) as $f) {
if ($_POST[$f] != "") {
$oopsie = "";
$email .= "$f : $_POST[$f]\n";
} else {
$oopsie = $oopsmsg;
$aok = 0;
}
$options = explode("|",$fields[$f]);
if (count($options) < 2) {
$form .= "<tr><td>$fields[$f] $oopsie</td>";
$form .= "<td><input name=$f value='".htmlspecialchars($_POST[$f])."'></td></tr>";
} else {
$form .= "<tr><td>$options[0] $oopsie</td>";
array_shift($options);
$form .= "<td><select name=$f><option value=''> -- Please Choose --";
foreach ($options as $maybe) {
$yes = ($maybe == $_POST[$f]) ? " SELECTED":"";
$form .= "<option value='$maybe'$yes>$maybe<br>";
}
$form .= "</select>";
}

}
$form .= "<tr><td> </td><td><input type=submit></td></tr></table></form>";

(I've given you a bit more there to put it in context)
