将PHP合并到HTML表格中

我想知道是否有人能够帮助我。将PHP合并到HTML表格中

我试图把功能，它允许管理员使用电子邮件地址作为搜索条件在mySQL数据库中搜索用户的详细信息。一旦搜索结果发生，我希望我的表单中的“第一”和“姓氏”字段在检索到的记录中完成。

我认为搜索工作的形式刷新，但它不检索任何可见的信息。

我只是想知道是否有人可能会看看我的代码，并让我知道我哪里出了问题。

非常感谢

您应经常检查或将其连接到查询之前santize你输入什么？如果有人要输入''; DROP TABLE userdetails; - 作为电子邮件？ –

@KileyNaro如果你正在尝试注册某些东西，我会说这相当适得其反：V – sg3s

严肃的一面，你没有告诉我们这个代码出了什么问题。你也可以用'$ email = mysql_real_escape_string（$ _ POST ['email']，$ connection）';'来代替当前的'$ email'声明来清理你的电子邮件。 – sg3s

只是在看你的代码breifly，我不认为你的电子邮件的价值正确地传递到您的SQL查询。

尝试使用此。

$result = mysql_query("SELECT * FROM userdetails WHERE emailaddress like '%" . $email . "%'");

PHP允许你在字符串中间使用变量，所以我不认为这是问题。 –

嗯，不知道，你的代码是用PHP做的，我来自C＃背景，所以对我来说看起来像是一个重大的错误。我应该保留我的答案还是删除它？ – alykhalid

嗨，我敢肯定，问题不在于电子邮件的价值不被传递，因为我已经尝试了这个作为一个单独的代码片，它工作正常。我发现一个挣扎是将表单和php结合在一起。非常感谢。 – IRHM

你不缺少的步骤，其中在实际运行针对您的查询mysql_fetch_assoc功能？只需将mysql_query的结果分配给变量$result是不够的！

您的来电后，加入这样的事情mysql_query：

if($result) 
{ 
    $row = mysql_fetch_assoc($result)); 
}

要获得所有的行导致与查询你需要使用MySQL取功能（有是几个）。

的优先停留方法是definitly mysql_fetch_assoc

你的代码的相关部分将是这个样子：

$email = mysql_real_escape_string($_POST['email']); // make the value safe for in the query 
$result = mysql_query("SELECT * FROM userdetails WHERE emailaddress like '%$email%'"); 
$rows = array(); 

while ($row = mysql_fetch_assoc($result)) { 
    $rows[] = $row; 
} 

// $rows is now a multi dimensional array with values found by the query

嗨，非常感谢您花时间帮助我解决这个问题。我对此很新，所以请原谅我对此采取的缓慢行动。我修改了我的代码以包含您的文本。表单呈现，我键入搜索条件，但唯一发生的是页面刷新。我已将更新的代码添加到我的原始帖子中。你能告诉我哪里出错了吗？问候 – IRHM

将结果放入数组后，您仍然必须使用'$ rows'做些事情。尝试'print_r（$ rows，true）;'查看从数据库获得的结果。如果它没有产生任何结果，那可能是因为没有任何结果。要重新检查一下，只需尝试在phpmyadmin中用您的输入电子邮件地址执行该查询并查看会发生什么。基本的PHP调试真的。阅读一些教程:) – sg3s
