Inputtext empty condition - bigboy81 - 05.03.2015

how to make if inputtext are blank server return that..

I try in my ways but doesn't work fine..

Код:

if(strlen(inputtext) < 1)
		{
 		   	SCM(playerid, COLOR_GREY,"Eror");
			return 1;
		}

Код:

if(strfind(inputtext, "", true) != -1)return  SCM(playerid, COLOR_GREY, "Eror");

Код:

if(!response)
{
    SCM(playerid, COLOR_GREY,"Eror");
    return 1;
}

Also i try with sscanf but if are emty server say him eror, but if i type something again server say eror..

All of these not work i need if the imputtext emty server return that and send him message with eror.

pawn Код:

#define isnull(%1) \
((!(%1[0])) || (((%1[0]) == '\1') && (!(%1[1]))))

Example:

pawn Код:

if(isnull(inputtext)) return SendClientMessage(playerid, -1, "Inputted text is null.")
else return SendClientMessage(playerid, -1, "Inputted text isn't null.")

It must work, the code shows, shows how you do it.

If i define isnull it tells me that it is already defined, like

Код:

warning 201: redefinition of constant/macro

But if i put

Код:

if(isnull(inputtext))

I can continue and I have not typed anything
I will try in my other methods

Just change the name of the macro.

PHP код:



#define lenull(%1) \
    ((%1[0] == 0) || (%1[0] == 1 && %1[1] == 0))


if(lenull(inputtext))
{
    SendClientMessage(playerid, -1, "text is null, insert correct text.");
}
else if(!lenull(inputtext))
{
    if(strlen(inputtext) >= 1 && strlen(inputtext) < 145) // 1 - 144 characters in inpittext
    {
    /// bla bla text not is null, and range correct 1-144 characters.
    }
    else SendClientMessage(playerid, -1, "Text incorrect min 1 character, max 144.");
}

Oh, I forgot to tell you to undefine it first.

Just add this before you define "isnull", obviously:

pawn Код:

#undef isnull
