[solved] confirm and output

[lian00]

Hello,
I want to use the confirm() function to ask if I want to continue to run an script or stop it but I'm a little lost. When I put only msg confirm("Ok?"); I've got two messages, the second with the value of the choice. And how to use this value to make a test ?
Thanks for any help.

Code: Select all

    $result = confirm("Continue script?", , , 4);
    if ($result) {
        echo "You clicked the yes button";
    } else {
        echo "You clicked the no button";
    }

Maybe a leeettle bit more explanation would help.

Confirm dialogs by default have Yes and Cancel buttons. When your press Yes, confirm() returns 1, else it returns 0. More buttons can be added, and each button has different integer return values.
if ($return) is true as long as $return is not empty nor 0, meaning its true as long as Cancel/No was not pressed

So

Code: Select all

$result = confirm("Continue script?", , , 4);

will show the message AND save the value in $result automatically ?

yes

Complement: I found the end function.
So

Code: Select all

 end confirm ("Continue script ?") == 1; 
    blablabla (script to continue);

Actually that will end the script if you press OK.
You should use

Code: Select all

 end confirm ("Continue script ?") != 1; //end if anything but OK pressed
    blablabla (script to continue);

end stops running the script if the condition is true. When the condition is confirm ("Continue script ?") == 1; it really means: end if confirm() returns 1 (which occurs when pressing OK/Yes)

You are right - I made the test :-)
