通过HTML更新PHP变量

标签： php html mysql

我希望能够使用HTML表单更改下面代码中的PHP变量$dispname和$banstat。

<?php
if (isset($_GET['p']) && $_GET['p'] == "login") {
$servername = "localhost";
$username = "foo";
$password = "bar";
$dbname = "wordpress";
$banstat = '1';
$dispname = "Brendan";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
} 

$sql = "UPDATE wp_oxygenpurchaseusers SET user_url=$banstat WHERE    display_name=$dispname";

if ($conn->query($sql) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $conn->error;
}

$conn->close();
}
?>

你需要获得$ _POST并设置变量

$dispname = $_POST['name'];

代码中的错误：

您打开两个表单，然后关闭一个

如果您想使用帖子，请检查 $ _ POST 

<?php
if (isset($_GET['p']) && $_GET['p'] == "login") {
   if ($_POST) {
      //update variables and update bd
   }
}
?>

您的代码中存在多个问题。

尝试

<?php
if (isset($_GET['p']) && $_GET['p'] == "login")
{
    /* Database Connection Info */
    $servername = "localhost";
    $username = "foo";
    $password = "bar";
    $dbname = "wordpress";

    // Create connection
    $conn = new mysqli($servername, $username, $password, $dbname);

    // Check connection
    if ($conn->connect_error)
    {
        die("Connection failed: " . $conn->connect_error);
    } 

    /* getting form values */
    $banstat = mysqli_real_escape_string($conn, $_GET['banstat']);//'1';
    $dispname = mysqli_real_escape_string($conn, $_GET['dispname']);

    $sql = "UPDATE wp_oxygenpurchaseusers SET user_url='$banstat' WHERE display_name='$dispname'";

    if ($conn->query($sql) === TRUE)
    {
        echo "Record updated successfully";
    }
    else
    {
        echo "Error updating record: " . $conn->error;
    }

    $conn->close();
}
?>

<input type="submit">

代码中的错误

  • 您打开两个表单。
  • 您在表单中使用post method，但在php代码中使用get method。
  • 您的变量未更新。

好的，所以我接受了@javi和@Hassan提供的其他答案并用它们重新编写它，我从Hassan获取了大部分代码然后用Javi改变了一些东西并将它们组合在一起。我想也许其他人可以使用它。再次感谢你们。

<?php
if (isset($_GET['p']) && $_GET['p'] == "login") {
if ($_POST) {
$servername = "localhost";
$username = "foo";
$password = "bar";
$dbname = "wordpress";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
} 
$banstat = $_POST['banstat'];
$dispname = $_POST['dispname'];
$sql = "UPDATE wp_oxygenpurchaseusers SET user_url=$banstat WHERE user_login='$dispname'";

if ($conn->query($sql) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $conn->error;
}

$conn->close();
}
}
?>
