PHP-Script- and function

translate

Since the release of r282 it is possible to process an own PHP function between the action “submit” and “sending the E-Mail”. This function can read all the form input, modify, and return it. See: PHP function include

In this function, the e-mail address can not be manipulated. If we need this possibility, we have to resort to another method.

A simple script in “template/inc_script/frontend_init/” -folder is processed before the PHP function call from the form.

Processing order:

1. Deliver the form to the browser
2. Submit: receiving the form with the user input
3. Processing the /frontend_init/ -Scripts
4. Processing PHP function call from the form

There are several regions, each is assigned an email address to contact the right person for this region.

• The region is one of many and can be selected in a pull-down menu. The email address of the contact person is assigned.
• It often happens that several regions will be managed by one person, thus stored identical email addresses.
• In the text of the initial email the selected region are shown.

The last requirement excludes the use of the form from PHP function because we can not relate in a typical building a response to the selected region. ($postvar['email'] ⇒ test@example.com) if e.g.

[select email menu] Name: email

Bitte wählen -|-
Babaorum -|- obelix@lokal.arpa
Laudanum -|- obelix@lokal.arpa 
Kleinbonum -|- asterix@lokal.arpa
Aquarium -|- idefix@lokal.arpa

If the user selects one of the first two places e.g. “Laudanum”, an identical e-mail address is returned to us, we do not know which location the user selects. (Obelix is responsible for both places).

Extended Version:

Bitte wählen -|-
Babaorum -|- <Babaorum>obelix@lokal.arpa
Laudanum -|- <Laudanum>obelix@lokal.arpa 
Kleinbonum -|- <Kleinbonum>asterix@lokal.arpa
Aquarium -|- <Aquarium>idefix@lokal.arpa

The form PHP function would provide in “$postvar['email'] ⇒ obelix@lokal.arpa”, thus also here no localisation would be possible. (<Laudanum> is filtered by the form Script).

The variable “$_POST['email']” in an frontend_init-Script supplies against it e.g. ” obelix@lokal.arpa”. We can determine the place.

To fix the location in the output text, we place a hidden field “location” with the word “nix” (nothing) into the form. This field can also be used to identify the form, the frontend_init script is executed on every page request!

Z.B.

 if(isset($_POST['email']) AND $_POST['email'] == 'nix') { ...

So kann das Formular zumindest rudimentär identifiziert werden. Dies kann bei mehreren Formularen in der Site wichtig sein.

Der letzte Schritt ist die Filterung des Ortes und Zuweisung zur Variablen “$_POST['ort']”.
Das ist mit einem einfachen preg_replace möglich, je nach Gusto.

    if (!defined('PHPWCMS_ROOT')) {
        die("You Cannot Access This Script Directly, Have a Nice Day."); }
// -------------------------------------------------------------------------------------------
 
if( isset($_POST['ort']) AND $_POST['ort'] == 'nix' )  // The right form?
{
    $email = trim($_POST['email']);
 
    $_POST['ort']   = preg_replace('/\<(.*)\>(.*)/is','$1', $email); // Cutting out the location
    $_POST['email'] = preg_replace('/\<(.*)\>(.*)/is','$2', $email); //Only for completeness. Is not necessarily needed
 
} // ---- END if( $_POST['ort']
 
 
?>

In der Formular PHP-Funktion wird in der Variablen “$postvar['ort'] der Text “Laudanum” stehen und somit auch in den Text der Ausgangs-eMail im Platzhalter ”{ort}” übernommen.
