为什么我的订阅页面没有将字段放在MySQL数据库中？

Question

I'm with a doubt,

I'm trying sending data to my database but it doesn't insert it them. How can i put them to send it?

index.php (script part):

<div id="wel">
        <p id="title-call">Junta-te <font color="gray">a n&oacute;s!</font></p><hr color="#c96308"  noshadow />
        <p id="subx">Percorre este mundo e torna-te o treinador n&uacute;mero <font color="#c96308">UM</font>!</p> 
    </div>  
    <div id="loading"><br /></div>
    <div id="warn2"><br /></div>
    <div id="success"><br /></div>
    <div id="subscribe">

            <input type="text" name="username" id="username" placeholder="Escreve aqui o teu Nome..." /><br />
            <br />
            <input type="text" name="email" id="email" placeholder="Escreve aqui o teu E-mail..." /><br /><br />

What can I do to this thing work guys?

Answer 1

You need to be checking for mysql errors, that would give you a big clue.

$query = "INSERT INTO subscribers VALUES('','$username','$email','$date')";
$sql = mysql_query($query) or throw new Exception("Query Failed: {$query}. Error: ".mysql_error());

Your code is open to SQL Injection, you should really be using MySQLi or PDO at this point, and if you're going to stick with mysql, escape your data.
