[code]

<?php
$to = "[email protected]";
$subject = "$idea";
$from_header = "From: $from";

if (isset($subject && $from_header)) {

mail($to, $subject, $contents, $from_header);
    
    echo 'Thank You, we will be sure to get back to you as soon as possible!';

}

else {
    echo 'Please go back and fill out the form';
}

?>

[/code]

gives me the error

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]
Parse error: parse error, unexpected T_BOOLEAN_AND, expecting ',' or ')' in /hsphere/local/home/way2fr3s/2fr3sh.com/links/email.php on line 10

Try it like so:

[code]if (isset($subject) && ($from_header)) {[/code]

Assuming that the form that gathered the information used method="post":

[code]<?php
$subject = trim(strip_tags($_POST['idea']));
$from = trim(strip_tags($_POST['email']));
$contents = trim(strip_tags($_POST['contents']));

if (($from!="") && ($contents!="")) {
    $to = "[email protected]";
    $from_header = "From: ". $from;
    mail($to, $subject, $contents, $from_header);
    echo 'Thank You, we will be sure to get back to you as soon as possible!';
} else {
    echo "You forgot something";
}?>[/code]

it is gathered using post
but using the following code

[code]
<?php
    $subject = "$idea";


if (($from!="") && ($contents!="")) {
    $to = "[email protected]";
    $from_header = "From: $from";
    mail($to, $subject, $contents, $from_header);
    echo 'Thank You, we will be sure to get back to you as soon as possible!';
} else {
    echo "Please go back and fill the form out correctly";

?>[/code]

gives me the error message

[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]Parse error: parse error, unexpected $ in /hsphere/local/home/way2fr3s/2fr3sh.com/links/email.php on line 17
[/quote]

the code ended up working in the end
thank you to all for your help

[code]
<?php
$subject = trim(strip_tags($_POST['idea']));
$from_header = trim(strip_tags($_POST['from']));
$contents = trim(strip_tags($_POST['contents']));

if (($from!="") && ($contents!="")) {
    $to = "[email protected]";
    $from_header = "From: ". $from;
    mail($to, $subject, $contents, $from_header);
    echo 'Thank You, we will be sure to get back to you as soon as possible!';
