I have this code:

PHP Code:

<?php

// function to output form and hold previously entered values.

function user_form() {
    
    //output the form HTML.
    echo '<p>Please fill in at least two fields.</p>';
    echo '<form action="'.htmlspecialchars($_SERVER['PHP_SELF']).'" method="post">';
    echo '<table border="0" cellspacing="4" cellpadding="0">';
    echo '<tr><td>Vertical Distance:</td><td><input type="text" name="VD" value="'.htmlspecialchars($_POST['VD']).'"></td></tr>';
    echo '<tr><td>Horizontal Distance:</td><td><input type="text" name="HD" value="'.htmlspecialchars($_POST['HD']).'"></td></tr>';
    echo '<tr><td>Throw Distance:</td><td><input type="text" name="TD" value="'.htmlspecialchars($_POST['TD']).'"></td></tr>';
    echo '<tr><td colspan="2"><input type="submit" value="submit" name="submit"></td></tr>';
    echo '</table>';
    echo '</form>';

}


// has the form been submitted?
if (isset($_POST['submit'])) {$error_str = '';
                                if( isset($_POST['VD'])) { if(!is_numeric($_POST['VD'])){$error_str .= '<li>VD must be a number</li>'; }
                                if( isset($_POST['HD']) ) { if( !is_numeric($_POST['HD'])){$error_str .= '<li>HD must be a number</li>'; }
                                if( isset($_POST['TD']) ) { if( !is_numeric($_POST['TD'])){$error_str .= '<li>TD must be a number</li>'; }
                                
                                 if (!empty($error_str)) {echo '<ul>'.$error_str.'</ul>';  user_form(); exit; }
                                 else {echo'Success!!';}                
                                
                                } else {user_form(); }
?>

And I'm getting this errer:

Parse error: parse error, unexpected $ in /home/.sites/22/site13/web/livexchange/tools/pc2.php on line 32

There is no dollar sign on line 32!

Any ideas?

Hehehe. Wanna know something else, there is no line 32.

So, what your actual error is, really on a line before the imaginary line 32.

I pasted the code into my editor and the page displays the same error. I thought it might have to do with some of your nested if statements and bracketing. Ask brandon, I am sure he can figure it out in a second or two.

I don't think its doing what you want since the script gives an error unless all 3 fields are filled in, but this will fix the parse error you're getting.

PHP Code:

<?php

// function to output form and hold previously entered values.

function user_form() {
    
    //output the form HTML.
    echo '<p>Please fill in at least two fields.</p>';
    echo '<form action="'.htmlspecialchars($_SERVER['PHP_SELF']).'" method="post">';
    echo '<table border="0" cellspacing="4" cellpadding="0">';
    echo '<tr><td>Vertical Distance:</td><td><input type="text" name="VD" value="'.htmlspecialchars($_POST['VD']).'"></td></tr>';
    echo '<tr><td>Horizontal Distance:</td><td><input type="text" name="HD" value="'.htmlspecialchars($_POST['HD']).'"></td></tr>';
    echo '<tr><td>Throw Distance:</td><td><input type="text" name="TD" value="'.htmlspecialchars($_POST['TD']).'"></td></tr>';
    echo '<tr><td colspan="2"><input type="submit" value="submit" name="submit"></td></tr>';
    echo '</table>';
    echo '</form>';

}


// has the form been submitted?
if (isset($_POST['submit'])) {$error_str = '';
                                if( isset($_POST['VD'])) { if(!is_numeric($_POST['VD'])){$error_str .= '<li>VD must be a number</li>'; } }
                                if( isset($_POST['HD']) ) { if( !is_numeric($_POST['HD'])){$error_str .= '<li>HD must be a number</li>'; } }
                                if( isset($_POST['TD']) ) { if( !is_numeric($_POST['TD'])){$error_str .= '<li>TD must be a number</li>'; } }
                                
                                 if (!empty($error_str)) {echo '<ul>'.$error_str.'</ul>';  user_form(); exit; }
                                 else {echo'Success!!';}                
                                
                                } else {user_form(); }
