hi guys,
i'm created a form mail script, doing quite good.
just that, after i enter certain value and hit submit button, it checks for error. if error found, it returns to the page but a blank page. i'll have to start keying in the value again.
is there a way to retain the value after error checking?
it's a one page form mail.
appreciate if you could help me out, thanks.
PHP Code:
<?php
session_start();
// Function to display form
function showForm($errorName=false,$errorEmail=false,$errorSubj=false,$errorMesg=false,$errorSec=false) {
if ($errorName) $errorTextName = 'Please enter a valid name.';
if ($errorEmail) $errorTextEmail = "Please enter a valid email address.";
if ($errorSubj) $errorTextSubj = "Please enter a valid subject.";
if ($errorMesg) $errorTextMesg = "Please leave a longer message.";
if ($errorSec) $errorTextSec = "Wrong security code.";
require("top.php");
echo '<title>Wanna contact me??</title>';
require("header.php");
echo '</head><body><div id="maincontent"><form action="contact.php" method="post">';
// Display name field an error if needed
echo 'Name : <input type="text" name="name" /><br />';
if ($errorName) echo "$errorTextName<br />";
// Display email field an error if needed
echo 'Email Address : <input type="text" name="email" /><br />';
if ($errorEmail) echo "$errorTextEmail<br />";
// Display subject field an error if needed
echo 'Subject : <input type="text" name="subj" /><br />';
if ($errorSubj) echo "$errorTextSubj<br />";
// Display message field an error if needed
echo 'Message : <textarea name="mesg" rows="5" cols="20"></textarea><br />';
if ($errorMesg) echo "$errorTextMesg<br />";
echo '<p><img src="contact/CaptchaSecurityImages.php" width="120" height="40" alt="security code" /></p><p><input type="text" name="security_code" /></p>';
