我有一个注册表单，它使用AJAX将数据传递给PHP脚本并将其输入MySQL数据库。
然而，我遇到的问题是当有人输入这样的用户名时： “用户名测试”空间未正确解析，因此当您通过链接查看该用户的个人资料时，它将无法正常工作。
所以我的问题是如果你知道如何在Javascript和PHP中解析一个空间，但我很确定PHP的一面是好的。
Firebug在提交表单时输出：
参数application / x-www-form-urlencoded emailSignUp nickdimartino91@gmail.com passwordSignUp nidima10 usernameSignUp用户名测试 资源 usernameSignUp =用户名+测试与安培; passwordSignUp = nidima10＆安培; emailSignUp = nickdimartino91％40gmail.com
我在PHP脚本中回显了用户名字段的值，并在用户名中返回一个空格。然而，它并没有以这种方式进入数据库。有什么问题？
更新：不确定我做了什么，但现在一切正常！
注册表单：
<form action="<?php echo $_SERVER['PHP_SELF'];?>" id="signUpForm" method="post" name="signUpForm">
<input class="formInput" id="usernameSignUp" name="usernameSignUp" placeholder="Username" required="required" type="text" style="margin-right: 6px;">
<input class="formInput" id="passwordSignUp" name="passwordSignUp" placeholder="Password" required="required" type="password" /><br>
<input class="formInput" id="emailSignUp" name="emailSignUp" placeholder="Email" required="required" type="email" style="margin-bottom: 10px; margin-top: 10px; width: 326px;"><br>
<input class="formButton" id="signUpSubmit" name="signUpSubmit" type="submit" value="Sign Up">
<div id="signUpLoading" style="display: none; height: auto; margin-top: 10px; width: auto;"><img alt="Loading" src="/images/loading.gif"><span class="loadingMessage">Signing up...</span></div>
<div id="signUpResponse" style="display: none; height: auto; margin-top: 10px; width: auto;"></div>
</form>
JS位用于执行AJAX：
<script>
$(document).ready(function() {
$("#signUpForm").submit(function() {
$(document).ajaxStart(function() {
$("#signUpLoading" ).show();
});
$.ajax({
url:"/ajax/signUp.php", // Action of the form
data:$("#signUpForm").serialize(), // Send forms data to server
dataType:"JSON", // Take response as JSON
type:"POST", // Send form by post or get
complete:function(result) {
$(document).ajaxStop(function() {
$("#signUpLoading" ).hide();
});
$("#signUpResponse").html(result.responseText);
$("#signUpResponse").slideDown("slow");
}
});
return false; // Default submit return false
});
});
</script>
