I'm following this article in order to validate my form
My problem is when I have to use the remote method, e.g. remote: "check-username.php"
Since the documentation for remote method is not so clear for me, I would know:
How I need to structure my json output in php script?
To use the default method for remote, the remote page must respond with a string value of "true" or "false".
Valid (success) Must be:
echo "true";
Invalid (failure):
echo "false"; // this can be any false. eg: 0 , "" , NULL.
The response will be evaluated as JSON.
To apply an error message, other than the default for a remote response of invalid ("false"), add the input name to the validator options messages object like so.
rules:{
username:{
remote: "check-username.php"
}
},
messages:{
username:{
remote: jQuery.format('{0} is already in use, please choose a different name')
}
}
You don't need JSON. You can put any text. For example you can
echo "success";
for passed validation, and enter validation message like:
echo "Username already exists.";
for failed validation.
In your callback do something like this:
remote: {
url: "check-username.php" ,
type: "post" ,
data: {
username: function() {
return $("#username").val();
},
complete: function(data){
if( data.responseText != "success" ) {
alert(data.responseText);
//handle failed validation
}
}
}
