isset undefined variable

Posted on 16th Feb 2014 07:03 pm by admin

Hi all,

Hope someone can point out the obvious. I've a log in script, if you dont enter a username or pw, you get a red asterix show by the field and a pop up.

If you enter an email but not the pw, it says Undefined variable: email_error .

This is the code:

// Validate the email address.
if (!empty($_POST['email'])) {
$e = escape_data($_POST['email']);
} else {
echo '<script type="text/javascript">alert("You forgot to enter your email address!");</script>';
#echo '<p class="error">You forgot to enter your email address!</p>';
$e = FALSE;
$email_error = '<span class="required"><img src="images/star.gif" /></span>';
}

// Validate the password.
if (!empty($_POST['pass'])) {
$p = escape_data($_POST['pass']);
} else {
$p = FALSE;
echo '<script type="text/javascript">alert("You forgot to enter your password!");</script>';
$pw_error = '<span class="required"><img src="images/star.gif" /></span>';
#echo '<p class="error">You forgot to enter your password!</p>';
}

My form looks like:

<form action="login.php" method="post">
<table border="0" width="310">
<tr>
<td><img src="images/email_address.gif" /></td>
<td><div class="myBoxLh"></div><input type="text" name="email" style="width:150px;" maxlength="90" value="<?php if (isset($_POST['email'])) echo $_POST['email']; ?>" /><div class="myBoxRh"></div><?php if (isset($_POST['submitted'])) { echo $email_error; }?></td>
</tr>
<tr>
<td><img src="images/password.gif" /></td>
<td><div class="myBoxLh"></div><input type="password" name="pass" style="width:150px;" maxlength="20" /><div class="myBoxRh"></div><?php if (isset($_POST['submitted'])) { echo $pw_error; }?></td>
</tr>
<tr>
<td colspan="2"><div align="left"><?php if (isset($_POST['submitted'])) { echo $error_message; }?></div><div align="right"><input type="image" src="images/submit.jpg" name="submit" value="Login" class="submit_small" /></div>
<input type="hidden" name="submitted" value="TRUE" /></td>
</tr>
</table>
</form>


How can I stop this error as I thought I'd coded the correct way?

Thanks in advance
