[RESOLVED] two part ereg within single condition

[BEFOR]

(must use ereg, knowing is it deprecated)

Looking to base the 2,5 parameters, on another $url variable value:

elseif((isset($_POST['ab'])) && (!ereg('^[1-9]+([\0-9\.,]{2,5})$', $Gformed)))

Have not had luck accomplishing this dynamically

if ($url=='12'){
$limits = "2,5";}
if ($url=='13'){
$limits = "1,3";}

Then of course placing $limits within the brackets.

Must this be done within a two part string? I am missing something obvious?

elseif((isset($_POST['ab']))&& (if($url==12)){!ereg('^[1-9]+([\0-9\.,]{2,5})$', $Gformed})))
if($url==13)){!ereg('^[1-9]+([\0-9\.,]{1,3})$', $Gformed))))

Well, you must use the " (double quote) to expand variables. Does that help?

[BEFOR]

I take it you mean within {2,5}

This is the best I can get it to take

$limits = "2,5";
{'.$limits.'}

Doing with the variable, the minimums work, but it doesn't always obey the maximum.

This is very strange, makes think it's getting corrupted. Maybe be the comma?
Is there a problem of checking numbers - which is what I'm doing?

Seperating the min and max vars out errors as well for the maximums.

$minL = "2";
$maxL = "5";
{'.$minL.','.$maxL.'}

Would it matter if this is preg match? (aside from being deprecated, it is php 4)

My point was that you have the regexp for your ereg() call written with single quotes:

ereg('^[1-9]+([\0-9\.,]$value)$');

Would it work with doubles?

ereg("^[1-9]+([\0-9\.,]$value)$");

I've a feeling I may have missed the point entirely.

I've a feeling I may have missed the point entirely.

I sincerely hope not, you're the only one to respond!

Anyway, the double quote gives the highly-coveted:

""Warning: ereg() [function.ereg]: REG_EBRACK

If you're putting it in double quotes, that may screw up back-slashes and the final "$". It might be simpler to stay with the single quotes and concatenate in the variable, or use sprintf() to build the regexp:

$regexp = '^[1-9]+([\0-9\.,]' . $value . ')$';
// ...or...
$regexp = sprintf('^[1-9]+([\0-9\.,]%s)$', $value);

// then:
ereg($regexp, $Gformed)

With double quotes, you'd have to do something like this to escape the back-slashes and the final "$":

$regexp = "^[1-9]+([\\0-9\\.,]$value)\$";

maybe its getting late, but I don't see where the $limits went.

I was extrapolating from dalescop's code. Presumably you would set the limit string within a variable, and use that variable where we put $value. If we go back to the original post where you set the variable $limits to be something like "2,3", then the regexp would be:

$regexp = '^[1-9]+([\0-9\.,]{' . $limits . '})$';

Does ereg have an inherent problem matching numbers?

I can't get the static {2,5} to even match correct. This is a bit insane for what it is.

[NogDog]

I don't know, I always use the preg_* functions, since they are (a) more powerful, (b) possibly a bit more efficient, and (c) not deprecated. 🙂

[BEFOR]

I see what you mean now NogDog. Though haven't had these difficulties with ereg previously (have it on another site without a problem & I haven't had the time to redo those) I don't feel entirely comfortable posting the preg_match since I said I had to use ereg -- but here it is:

$Gformed = str_replace(',','', $Gvar); // removing comma

!preg_match('/^(0|[1-9]\d{'.$limits.'})$/', $Gformed ) // periods simply denied

//then to render

$Gready = number_format($Gformed);

Much appreciate the help & understanding.
