zExtendedRegistration - throws errors - not working 2.11.4

Good morning:

I installed a copy of z Extended Registration extension which I think might help one of my clients with some of its features including "recommending" another person to register. The installation went smoothly, but when I clicked on the "member" link in the Account Manager Contao goes to a white screen of death.

Error log shows

Code:

---

[06-Jul-2012 16:50:53] PHP Parse error:  syntax error, unexpected ':' in /home/wavedev3/public_html/system/modules/zExtendedRegistration/dca/tl_module.php on line 228

---

Line 228 in Dreamweaver of the tl_module.php file has a red highlight on it for the error, and the line is in this block

Code:

---

// add additional fields from form to field list
                if($dc->activeRecord->extReg_addformfields)
                {
                        // get form fields selected
                        $objFormfields = $this->Database->prepare("SELECT * FROM tl_form_field WHERE pid=? AND invisible!=1 ORDER BY sorting")
                                                        ->execute($dc->activeRecord->extReg_form);
       
                        if(!$objFormfields->numRows)
                        {
                                return $return;
                        }
                       
                        while($objFormfields->next())
                        {
                                if(!strlen($objFormfields->label))
                                {
                                        $objFormfields->label = $objFormfields->name ?: $objFormfields->type . $objFormfields->id; //1 - LINE 228
                                }       
                                if(!strlen($objFormfields->name))
                                {
                                        $objFormfields->name = $objFormfields->type . $objFormfields->id;
                                }
                               
                                $return[$objFormfields->name] = $objFormfields->label . ' <span style="color:#b3b3b3">['.$objFormfields->name.':'.$objFormfields->type.']</span>';
                               
                        }
                }

---

If I take Line 228

Code:

---

$objFormfields->label = $objFormfields->name ?: $objFormfields->type . $objFormfields->id; //1

---

and modify it to

Code:

---

$objFormfields->label = $objFormfields->type . $objFormfields->id; //1

---

the error flag in Dreamweaver clears but then I get multiple errors when I click on the "Member" link. Errors thrown now are:

Code:

---

I went ahead and uninstalled the extension manually and ran the install tool to clear the database. Anybody have any ideas on this or already have a solution?

Ernest, I think this extension will only run on php 5.3
The author has used terniary shorthand in his code (recognised by php 5.3 and up) which means it is really only compatable with Contao 3 (which will also require php5.3) - as the system requirements for Contao 2.x.x are php 5.2.

Terniary shorthand is

Code:

---

$objFormfields->label = $objFormfields->name ?: $objFormfields->type . $objFormfields->id;

---

instead of

Code:

---

$objFormfields->label = ($objFormfields->name ?$objFormfields->name : $objFormfields->type . $objFormfields->id);

---

The author should change all instances of this if he wants it truly compatable with Contao 2.x.x
