SyntaxError: identifier starts immediately after numeric literal in Firebug

Question

I\'m getting that error when I call this javascript function:

function kickUser(id_userChat){
$.post(\"chatFuncs.php\", { action: \"kick\", id_user: id_userC         


        

Answer 1

The resulting JavaScript code will be

kickUser(userName)

…and obviously there is no js variable userName. You want to pass a string instead:

kickUser('userName');

So add the quotes/apostrophes to the output, and don't forget to escape the $rowUsers['userName'] properly. It's quite the same for $rowUsers['id_user'], which seems to have output even an invalid identifier.

Answer 2

Identifiers in JavaScript can't begin with a number; they must begin with a letter, $ or _.

I'm guessing it's coming from this:

onclick="kick_user('.$rowUsers['id_user'].')">Kick</a>

If you mean to pass a string, then you need to quote the value being passed.

onclick="kick_user(\"'.$rowUsers['id_user'].'\")">Kick</a>

I don't know PHP, so maybe you need different escaping, but this should give you the idea.
