当我提交时我试图再次转到index.php？page=servers，但是当我提交表单时重定向是index.php？但实际上是index.php?page=servers 我该如何解决这个问题？
<form class="form-horizontal" action="index.php?page=servers">
<fieldset>
<legend>Add server</legend>
<div class="form-group">
<label for="inputEmail" class="col-lg-2 control-label">IP</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="ipserver" placeholder="IP Adress">
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="col-lg-2 control-label">Port</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="portserver" placeholder="Port">
</div>
</div>
<div class="form-group">
<label for="select" class="col-lg-2 control-label">Type</label>
<div class="col-lg-10">
<select class="form-control" id="select">
<option>Half-Life (Counter-Stricke)</option>
<option>Minecraft</option>
</select>
</div>
</div>
<div class="form-group">
<div class="col-lg-10 col-lg-offset-2">
<button class="btn btn-default">Cancel</button>
<button type="submit" id="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</fieldset>
</form>
And php
if(!empty($_POST['submit'])){
$ip_server = $_POST['ipserver'];
$port_server = $_POST['portserver'];
if ($ip_server == NULL || $port_server == NULL){
echo 'Моля попълнете всички полета.';
}else{
$type = "halflife";
$zone = 0;
$disabled = 0;
$status = 1;
$sql = ("INSERT INTO `lgsl` (type, ip, c_port, q_port, zone, disabled, status) VALUES ('$type', '$ip_server', '$port_server', '$port_server', '$zone', '$disabled', '$status')");
$result = mysql_query($sql);
echo 'Сървъра е успешно добавен!';
}
}
默认表单 HTTP 方法是什么？
您需要向表单标记添加一个属性，以根据您的代码将其转换为 POST。
<form method="POST">
$_POST 与 $_SERVER['REQUEST_METHOD'] == 'POST'
要验证请求，请使用：
if( $_SERVER["REQUEST_METHOD"] == "POST" ) // or GET, if appropriate
如果您打算使用 GET，则可以添加一个名为“page”和值“servers”的隐藏元素。
<input type="hidden" name="page" value="servers" />
