Javascript function with PHP throwing a "Illegally Formed XML Syntax" error
- by Joe
I'm trying to learn some javascript and i'm having trouble figuring out why my code is incorrect (i'm sure i'm doing something wrong lol), but anyways I am trying to create a login page so that when the form is submitted javascript will call a function that checks if the login is in a mysql database and then checks the validity of the password for the user if they exist. however I am getting an error (Illegally Formed XML Syntax) i cannot resolve. I'm really confused, mostly because netbeans is saying it is a xml syntax error and i'm not using xml. here is the code in question:
function validateLogin(login){
login.addEventListener("input", function() {
$value = login.value;
if (<?php
//connect to mysql
mysql_connect(host, user, pass) or die(mysql_error());
echo("<script type='text/javascript'>");
echo("alert('MYSQL Connected.');");
echo("</script>");
//select db
mysql_select_db() or die(mysql_error());
echo("<script type='text/javascript'>");
echo("alert('MYSQL Database Selected.');");
echo("</script>");
//query
$result = mysql_query("SELECT * FROM logins") or die(mysql_error());
//check results against given login
while($row = mysql_fetch_array($result)){
if($row[login] == $value){
echo("true");
exit(0);
}
}
echo("false");
exit(0);
?>) {
login.setCustomValidity("Invalid Login. Please Click 'Register' Below.")
} else {
login.setCustomValidity("")
}
});
}
the code is in an external js file and the error throws on the last line. Also from reading i understand best practices is to not mix js and php so how would i got about separating them but maintaining the functionality i need?
thanks!
