我想从我的用户注册页面（signin_up.php）通过我的确认页面（confirm_validation.php）传递变量'region_name'，最后到我的区域首页（regional_head_page.php），我可以在那里查询从我的数据库引用变量（region_name）。这是我各自页面的代码：
signin_up.php
<form id="form1" name="form1" class="form-signin" method='post' action="confirm_validation.php">
<div class="">
<label for="inputFirstName" class="sr-only">First Name</label>
<input name="fname" type="name" id="inputfname" class="form-control" placeholder="First Name" required autofocus>
</div>
<div class="">
<label for="inputMiddleName" class="sr-only">Middle Name</label>
<input name="mname" type="name" id="inputmname" class="form-control" placeholder="Middle Name">
</div>
<div class="">
<label for="inputLastName" class="sr-only">Last Name</label>
<input name="lname" type="name" id="inputname" class="form-control" placeholder="Last Name" required>
</div>
<div class="">
<label for="inputDistrict" class="sr-only">District</label>
<input name="district_name" type="name" id="inputdistrict" class="form-control" placeholder="District" required>
</div>
<div class="">
<label for="inputEmail" class="sr-only">Email</label>
<input name="eemail" type="email" id="inputEmail" class="form-control" placeholder="Email" required>
</div>
<div class="">
<select name="access_level" class="form-control" placeholder="Position" id="access_level" required>
<option>Please Select your Position</option>
<option value="regional_head">Regional Head</option>
<option value="general_user">General User</option>
</select>
</div>
<div class="">
<select name="region_name" class="form-control" placeholder="Region" id="region_name" required>
<option>Please Select your Region</option>
<option>Greater Accra Region</option>
<option>Eastern Region</option>
<option>Western Region</option>
<option>Central Region</option>
<option>Ashanti Region</option>
<option>Volta Region</option>
<option>Brong Ahafo Region</option>

</select>
</div>
<div class="">

您已使用session_start();。所以在会话中传递数据。
ob_start();
session_start();
if(isset($_POST['signup'])){
$con=mysqli_connect("localhost","root","myspace4199","car_sales");
// Check connection
if (mysqli_connect_errno()) {echo "Failed to connect to MySQL: " . mysqli_connect_error();}
$user_signup = "user_signup";
$fname = mysqli_real_escape_string($con, $_POST['fname']);
$mname = mysqli_real_escape_string($con, $_POST['mname']);
$lname = mysqli_real_escape_string($con, $_POST['lname']);
$district_name = mysqli_real_escape_string($con, $_POST['district_name']);
$eemail = mysqli_real_escape_string($con, $_POST['eemail']);
$access_level= mysqli_real_escape_string($con, $_POST['access_level']);
$region_name = mysqli_real_escape_string($con, $_POST['region_name']);
$district_pass = mysqli_real_escape_string($con, $_POST['district_pass']);
$_SESSION['region_name'] = $region_name;
//If user is a regional head
if($access_level == 'regional_head'){
$sql="INSERT INTO user_signup (eemail,mobile_number,fname,mname,lname,access_level,district_name,district_pass) VALUES ('$eemail','$mobile_number','$fname','$mname','$lname','$access_level','$district_name','$district_pass')";
$_SESSION['eemail'] = $eemail;
header('Location: regional_head_page.php');
}
else if ($access_level == 'car_company'){
$sql="INSERT INTO user_signup (eemail,mobile_number,fname,mname,lname,access_level,district_name,district_pass) VALUES ('$eemail','$mobile_number','$fname','$mname','$lname','$access_level','$district_name','$district_pass')";
$_SESSION['eemail'] = $eemail;
header('Location: car_company_page.php');
}
if (!mysqli_query($con,$sql)) {
die('Error: ' . mysqli_error($con));
}
echo "";
mysqli_close($con);
}
?>
在regional_head_page.php中
<?php
session_start();
$con=mysqli_connect("localhost","root","myspace4199","car_sales");
// Check connection
if (mysqli_connect_errno()) {echo "Failed to connect to MySQL: " . mysqli_connect_error();}
if ( isset($_SESSION['region_name']) ) {
$region_name = $_SESSION['region_name'];
} else {
// got a problem, deal with it here
}
$sql="SELECT * FROM general_reservation WHERE region_name = '$region_name'";
$records=mysqli_query($con,$sql);
?>

在我看到您的代码之后，首先是您为什么不在<?php $currentwidth中使用<script>代码。
现在你也可以这样做：
在文件</script>中：
改变regional_head_page.php
到confirm_validation.php
答案 2 :(得分：0)
尝试使用会话，或者您可以在查询字符串中传递该变量值。
查询字符串：标题（'位置：regional_head_page.php？region_name ='。$ region_name）;
OR
Session = $ _SESSION ['region_name'];
