[SOLVED] Eregi_Replace - replaces needle with ?

MCrosbie · January 14, 2008

I have a function for sending email using email templates. This is for transactional emails. Inside these email templates are variables, e.g. {var customer.id}.

This is the function:

// TRANSACTIONAL EMAILS SEND
function transaction_email($tag,$var = array(),$sendto){
$res_template = mysql_query("Select * from DM_email_templates where tag='".$tag."'");
$row['template'] = mysql_fetch_array($res_template);
$message = $row['template']['content'];
$subject = $row['template']['subject'];
foreach ($var as $tags => $data) {
        $message = eregi_replace("{" . $tags . "}", $data, $message);
	$subject = eregi_replace("{" . $tags . "}", $data, $subject);
}
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: '.DM_site('website_name').' <'.DM_site('admin_email').'>' . "\r\n";
mail($sendto['name']."<".$sendto['email'].">",$subject,$message, $headers);
}

This is a call to the function for it to send:

$sendto['name'] = $form['billed_to'];
$sendto['email'] = $row['custid']['email'];
transaction_email('new_invoice',array(
        "var invoice.total" => $calc[0],
"var invoice.id" => $invoice_id,
"var customer.id" => $row['custid']['id'],
"var customer.company" => $calc[4]['company'],
"var customer.fname" => $calc[4]['fname'],
"var customer.lname" => $calc[4]['lname'],
"var customer.address" => $calc[4]['address'],
"var customer.address2" => $calc[4]['address2'],
"var customer.city" => $calc[4]['city'],
"var customer.state" => $calc[4]['state'],
"var customer.country" => $calc[9], 
"var customer.telephone" => $calc[4]['telephone'],
"var customer.email" => $calc[4]['email'],
"var invoice.created" => $calc[5]['created'],
"var invoice.due" => $calc[5]['due'],
"var invoice.paid" => $calc[5]['paid'],
        "var invoice.statement" => $calc[10],
"var site.name" => DM_SITE('website_name'),
"var site.addr" =>  "http://".$_ENV['SERVER_NAME'].""
),$sendto);

Now the problem I have, and it has only happened with the above example, is that both var invoice.total and var invoice.id don't come through.

var invoice.total simply replaces the tag with nothing. I have checked and the value ($calc[0], lets say it is 28 for now), and it is passed all the way till eregi_replace, and even afterwards, but for some reason it doesn't replace it with the value, rather it replaces it with " " - nothing.

var invoice.id is a similar situation, but instead of replacing it with nothing it replaces it with a "?". I can think of no logical reason for why it would be doing this.

I have tried to change the names of the variable and change the values, but nothing seems to change the outcome.

Please help!

So, I assume your templates are something like this:

This is Invoice # {var invoice.id} for customer id # {var customer.id}

Well, your template might be wrong.

Show us your 'new_invoice' template, and the values of $calc[0] and $invoice_id.

</html>

The values are as follows:

$calc[0] = 28

$invoice_id = 101067

Type cast the values as string or format the number in the case of the total. Example:

transaction_email('new_invoice',array(

"var invoice.total" => number_format($calc[0], 2, '.', ','),

"var invoice.id" => (string) $invoice_id,

.

Worked like a charm!

Can you explain the difference that that has made and why it worked?

toplay · January 15, 2008

Not really sure since I don't work with ereg_xxx functions too much.

If you use preg_replace() instead you won't have that problem.

This:

$message = preg_replace("/{" . $tags . "}/i", $data, $message);

will work fine with what you already have:

transaction_email('new_invoice',array(

"var invoice.total" => $calc[0],

"var invoice.id" => $invoice_id,

.

Brilliant. Thanks for all your help, it's greatly appreciated.
