Help with constant

[lingo5]

Hi,

Please can someone tell me why the text in my constant is not displaying?

if($totalRows_checkdup_RS==1)
{
$errorMsg =  '.CNT_TXT_WARNING_EMAILEXISTE.'; // I want this constant to print a warning message but all I get printed is the constant!!!
}

else{

Don't quote the constant.

 

$errorMsg = CNT_TXT_WARNING_EMAILEXISTE;

Thanks Pikachu, that worked..even though I don't uderstand the logic of it :-)

Anything within single quotes is interpreted as a string literal. Anything within double quotes is interpreted as a string unless prefixed with $ which makes it a variable. There's no way to tell the difference between what should be interpreted as a string literal and what should be interpreted as a constant within double quotes because there is no prefix to indicate that the value is a constant. Look at the quoting, and paste this code into a script to see how each is handled.

 

<?php
define( 'error', 'There has been an error!' );
$error = 'Something cratered';

echo 'error<br>';
echo '$error<br><br>';

echo "error<br>";
echo "$error<br><br>";

echo $error . '<br>';
echo error;
