Error in jquery return

Question

I’m using php + jquery

return is a string of type

[["local","pressão instantânea"],["Campo Grande",1010.6],["Campo Grande",1011.1],["Campo Grande",1010.2]]

Being that in the return comes some strange metadata. I’ve read something about CDATA. But, I didn’t understand how to solve this issue. Someone would know to give a help?

$.ajax({
    type: 'POST',
    url: link,
    data: {
        idAtt: attributes,
        idData: idData
    }
}).done(function(data) {

    alert(data);
    console.log(data);
}

Answer 1

I think the problem is due to an error that triggers the debugger of the framework you are using. With this, the debugger of this framework prints the information, which is a kind of backtrace of the debugger, along with the json result.

What you call "metadata" I assume is the backtrace of the framework debugger.

Fix the error pointed by the debugger and you probably won’t have the problem anymore.

According to debug, the error is this:

Undefined variable: cases in /var/www/html/dashboard_admin/models/eav-model.php on line 716

An undefined variable, called "cases" in the file /var/www/html/dashboard_admin/models/eav-model.php on line 716.
