[RESOLVED] Self submit form with error messages

[ade234uk]

I can self submit a form no problems.

I would like to know if there are any tutorials that show you how to create a self submitting form with error checking. The error checking and message appears above the formwhen the field has been missed out.

If all is ok the form get mailed, which I can do.

Many Thanks

Ok to break it down. This is how I do a self submitting form.

<? if (!isset($_POST['submit'])) { ?>

<form method="post" action="testform.php">
<input name="first_name" type="text">
<input name="surname" type="text">
<input type="submit" name="submit" value="Send Enquiry">
<form>

<?
} else {

if ($first_name) { echo"Please enter first name"; exit(); }
if ($surname) { echo"Please enter surname"; exit(); }}

echo "Form submitted";
?>

how is that "self submitting" ???

your else clause makes no sense... the logic is backwards on the checks and could easily be re-written

<?php
$form = "<form method=\"post\" action=\"testform.php\">
<input name=\"first_name\" type=\"text\">
<input name=\"surname\" type=\"text\">
<input type=\"submit\" name=\"submit\" value=\"Send Enquiry\">
<form>";

if (!isset($_POST['submit'])) 
{ 
echo $form;
} 
elseif (empty($_POST['first_name']))
{
echo"Please enter first name"; 
echo $form;
exit();
}
elseif (empty($_POST['surname']))
{
echo"Please enter surname"; 
echo $form;
exit();
}
else
{
echo "Form submitted";
}
?>

Thats excellent. You have really managed to clean up the code. I will give this a go in a minute.

Still not the best way of handling errors, however, as if you had more than the two fields, the code could get very long and tedious.

Although in the meantime that should do you :p
