TYPO3 Core

The problem seems to be using " instead of ' in line 249.

if (ereg("^{[\$][a-zA-Z0-9\.]*}$",trim($fV),$reg)) { // Values entered from the constantsedit cannot be constants! 230502; removed \{ and set {

For me, it looks, as if somebody tried to check for a value of the form {something} but as PHP replaces escaped chars within " strings, the ereg never will get the \{, which was first tried. Replacing the " by ' and reinserting the \ in front of { and } removes the error message, but of course if have no idea, whether this is, what really was intended.

The same code you'll find in class.t3lib_tsparser_ext.php.

The attached patch should solve the problem, though I didn't check it. Please confirm.

At the moment I have no chance to check the patch because I can't reproduce the error. It appeared very seldom f.e. when installing extensions.

But AFAIK the ^ in the beginning should fall behind the / and the $ at the end should be before the /. With this changes the patch would do the same (AFAICS) as an if (ereg('^\{[\$][a-zA-Z0-9\.]*\}$',trim($fV),$reg)) which I tested positively, when the error appeared.

Anyway I have no clue when this test should happen. So if anybody can tell it, I'll perhaps be able to reproduce it.

Ouch! Of course you are right, I've changed that now.
What I find strange is that Kasper has added a comment on that line, stating the he changed the syntax from "\{" to "{". However, from a logical point of view, this seems to be a mistake.

Fixed in CVS
