[RESOLVED] .= in a mail function

stuartbrown20

Hey everyone...

I have a mail script where $message is the content for the email and calls a bunch of $_POST vars and then emails them to me... There's one section where i need an if statement to go thru a bunch of similarly named vars and put them in the mail just for nice formatting reasons (instead of calling each one individually, but i found that u can't have an IF statement inside $message...

So i'm trying to use .= instead and i now have this...

$message .= 
for ($i = 1; $i <= 29; $i++) {
if ( $_POST['option$i'] != NULL)
<br>" . $_POST['option$i'] . " (" . $_POST['$i']. ")
}

I know it's jst meant to drop in there somehow when $message is called but doesn't seem to work. Am i not understanding how it's meant to work???

Please help. :queasy:

$message = "";
for ($i = 1; $i <= 29; $i++) { 
	if ( $_POST["option{$i}"] != NULL) 
		$message.= $_POST["option{$i}"] . " ({$_POST[$i]})<br />";
}

U need to understand what is the difference between a string encapsulate in double quote and simple quote is and how to concatenate strings ...
U should look into foreach too..

To make life much easier on your porcessing page (the one you are posting to, or the one named in the action='whatever.php) create short variables.

<?php
$username = $_POST['username'];
$firstname = $_POST['firstname'];
$lastname =$_POST['lastname'];
$email= $_POST['email'];
...
...
?>

This will allow the use of a regular variable in a string without worrying about using Double quotes;

echo "Hello $first $last, <br />The e-mail you entered was $email. Is this correct?";
blah blah blah

Is there somewhere i can goto on the net with a good reference for syntax and stuff like that? I find that my biggest problem writing php is getting the syntax correct so big appologiest to my errors with that.

Ok also one last thing... the $message .= works great now thanks for the help bogu 😃😃

Now in the $message it calls some variables here and there but i would really like the information within $message .= to be at the top of the email rather than at the end. Is this possible to do?

Then add the for loop at the beginning of the script where u create your mail message.
".=" means concatenation ...

/* declare $message variable */
$message = ""; 
for ($i = 1; $i <= 29; $i++) { 
    if ( $_POST["option{$i}"] != NULL) 
        /* if the value on post is not null concatenation post values to the message */
        $message.= $_POST["option{$i}"] . " ({$_POST[$i]})<br />"; 
}
/* from here we add the rest of the message */
$message.= "Some other stuff here...<br />";
$message.= "More other stuff here...<br />";
$message.= "--------------------------------<br />";
$message.= "Something like,<br />";
$message.= "a signature here<br />";
$message.= "http://www.php-core.com<br />";
/* this body is a html format */
echo $message;    // to see how your mail body will look like ...
