$this->User->isAdmin

I'm trying to make a DCA customization very similar to what's here:
http://www.contao.org/custom-configurations.html

Code:

---

// system/config/dcaconfig.php
// Allow only admins to add articles
if (!$this->User->isAdmin)
{
$GLOBALS['TL_DCA']['tl_article']['config']['closed'] = true;
}

---

The IF statement is always returning false, even if I'm logged in as an admin. Has this changed since publication (I'm using 2.8.3)?

Please show us what is return isAdmin by
[code=php:b2sijnc0]<span class="syntaxdefault">
var_dump</span><span class="syntaxkeyword">(</span><span class="syntaxdefault">$this</span><span class="syntaxkeyword">-></span><span class="syntaxdefault">User</span><span class="syntaxkeyword">-></span><span class="syntaxdefault">isAdmin</span><span class="syntaxkeyword">);
</span><span class="syntaxdefault">*</span>[/code:b2sijnc0]
Is it false?

Have you imported the BackendUser?
[code=php:b2sijnc0]<span class="syntaxdefault">
$this</span><span class="syntaxkeyword">-></span><span class="syntaxdefault">import</span><span class="syntaxkeyword">(</span><span class="syntaxstring">'BackendUser'</span><span class="syntaxkeyword">,</span><span class="syntaxdefault">*</span><span class="syntaxstring">'User'</span><span class="syntaxkeyword">);
</span><span class="syntaxdefault">*</span>[/code:b2sijnc0]

Just to clarify, I've added that code directly into /system/config/dcaconfig.php -- as that's what the Developer's Guide recommends.

Inside dcaconfig.php, $this->User returns a valid BackendUser object (it's way too long to post). So I don't think I need to import anything here. I do see a protected variable, 'admin', which is set to "1/true".

Trying to var_dump $this->User->isAdmin in this file gets me a content encoding error, so I can't see directly what it is set to.

However, if I save it --

Code:

---

$GLOBALS['YOURMOM'] = $this->User->isAdmin;

---

And spit it out it in my be_main.tpl file --

Code:

---

echo( $GLOBALS['YOURMOM'] );

---

It shows blank/false, which it shouldn't, since I'm definitely logged in as an admin.

However, if I just put this into my be_main.tpl file --

Code:

---

        $this->import('BackendUser', 'User');
        echo($this->User->isAdmin);

---

It DOES return 1/true.

I have just tested this in Contao 2.9 beta1 and looks good:
[code=php:2rfww3q1]<span class="syntaxdefault">
</span><span class="syntaxcomment">//*system/config/dcaconfig.php
</span><span class="syntaxdefault">var_dump</span><span class="syntaxkeyword">(</span><span class="syntaxdefault">$this</span><span class="syntaxkeyword">-></span><span class="syntaxdefault">User</span><span class="syntaxkeyword">-></span><span class="syntaxdefault">isAdmin</span><span class="syntaxkeyword">);
</span><span class="syntaxdefault">*</span>[/code:2rfww3q1]
returns twice true and once null. I think it's either a bug or issue caused by a custom extension.

I hope more advanced developers will help you :)

Try this to see if it makes a difference... it probably won't but hey!

Code:

---

$this->import('BackendUser', 'User');
if ($this->User->isAdmin)
{
$GLOBALS['TL_DCA']['tl_article']['config']['closed'] = false;
}else
{
$GLOBALS['TL_DCA']['tl_article']['config']['closed'] = true;
}
