Only Numbers

Hello,

I'm pretty sure it was a function like this.

So, It check If the entered words contain only numbers, no words

PHP Code:


		
			
new szArg[192];
    read_args( szArg, charsmax( szArg ) );
    remove_quotes( szArg );
    new ids = str_to_num(szArg)
    
    if(ids == 0) {
        culoare(id, "!g[!tSYSTEM!g] !tWe Accept Only Numbers")
        return PLUGIN_HANDLED;
    }

If I write like 123456 it block me
But If I type 123456A, it allow him and pass next

Re: Only Numbers

Use is_str_num()

Re: Only Numbers

PHP Code:


		
			

stock bStringAreNumbers(const String[])
{
   for(new i, maxloop = strlen(String); i < maxloop; i++)
   {
      if( ! ( '0' <= String[ i ] <= '9' ) ) return false;
   }
   return true;
}

although listen for what bugsy told you, this example is just for clarification!

Re: Only Numbers

My bad, I wanted to say that If I type 123456 [Need to type regular numbers to pass] it let me go, but If I type 123456A it still pass me <-- [And this is what I want to block] [What I want to block it's that , If I type some numbers and in that numbers contain a words is should return ]

Re: Only Numbers

It lock like doing it negative it solved my problem

PHP Code:


		
			
if(!bStringAreNumbers(szArg)) {
        culoare(id, "!g[!tSYSTEM!g] !tWe Accept Only Numbers");
        return PLUGIN_HANDLED;
    }

Re: Only Numbers

Or:

PHP Code:


		
			
stock bool:xValidNumber(const xStr[])

{

    new const xNumbers[][] =

    {

        "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"

    }

    

    new xLen = strlen(xStr)

    new i, a, xValids

    

    for(i = 0; i < xLen; i++)

    {

        for(a = 0; a < sizeof(xNumbers); a++)

        {

            if(xStr[i] == xNumbers[a][0])

            {

                xValids ++

                break

            }

        }

    }

    

    if (xValids != xLen)

        return false

    

    return true

}

Re: Only Numbers

Beating this one to death guys..I'd just use the native is_str_num() and call it a day. Natsheh's function is better/more efficient than what you posted, loiraolhosazul.
