Ereg problem: string beginning with

[Anon]

When the user name begins with 'string' like 'string-1' or 'string2' etc, the user get 'not available' message.
but error occured when a user name not beginning with 'string' like 'theuser', it also shows the 'not available' message.

$eregstr2="^{string[0-9_-]{0,}$";}
if(!ereg($eregstr2,$str)){
echo "The user name is not available.";
exit;

Thanks

Hello,
Try this:

$eregstr2="^{(string[0-9_-]*)$";}
if(!ereg($eregstr2,$str)){
echo "The user name is not available.";
exit;
} //endif

If that doesn't work, remove the caret (⁾ or the $ and try that. If that doesn't work, strip your pattern down to its most simple level and build it up slowly from there. In this case, make your pattern "string2" and make sure that's working. Then go to "string[0-9]" and make sure that works. Add more restrictions as you go, that way you can debug along the way.
