服务器端验证入门 [英] Getting Started with Server-Side Validation
问题描述
好的，我正在尝试为我正在创建的网站创建一个php模型。 php脚本必须有一个验证脚本来检查表单，图像验证脚本以及向数据库提交信息。到目前为止，我已阅读了许多一半的书面教程，这些教程解释了一些事情，我要求个人一对一的帮助，要么就正确的方向指出如何实现这个目标。到目前为止，这是我的工作代码，它并不多，但我想它是一个开始。希望借助这个论坛来帮助我解决这些问题。非常感谢你。

//如果所有表单字段都已正确提交，开始处理
如果（$ valid_form == true）

我有表格的各种输入，包括确认密码。希望有人可以提供帮助。
Ok, i am trying to create a php model for a website I am creating. The php script must have a validation script to check form, a image verification script and a submission of the information to a database. So far, i have read many half written tutorials that explained things but not in detail. I am asking either for personal one on one help with this or a point in the right direction as to how to accomplish this. So far this is the code i have for my work, its not much but i suppose its a start. Would love the help of this forum to get me past these issues. Thank you very much.
[PHP]<? php
//Determine if the sumbit button has been clicked. If so, begin validating form data.
if ($_POST[''submitB''] == "Submit")
{
//Determine if a Name was entered
$valid_form = true;
if ($_POST[''name''] == "")
{
echo "Enter your name";
$valid_form = false;
}
else
{
$name = $_POST[''name''];
}
if ($_POST[''uname''] == "")
{
echo "Enter a user name";
$valid_form = false;
}
else
{
$username = $_POST[''uname''];
}
if ($_POST[''pass''] == "")
{
echo "Enter a password";
$valid_form = false;
}
elseif (strlen($_POST[''pass'']) < 4)
{
echo "Password must contain at least 4 characters";
$valid_form = false;
}
else
{
$password = $_POST[''pass''];
}
//if all form fields were submitted properly, begin processing
if($valid_form == true)
{
//form processing code goes here
}
}
?>
[/PHP]
I have all kinds of inputs for the form, including a confirm password. Hopefully someone can help.
