我有一个显示某些信息的角色数据库。当我点击“更新信息”时,它会将我带到一个HTML表单,我可以在其中更新当前信息。当我填写新信息并点击“更新”时,我收到以下错误:
警告:mysqli_stmt :: bind_param():类型定义字符串中的元素数与第59行/home3/tarb89/public_html/aususrpg.net/charbase/updated.php中的绑定变量数不匹配 绑定参数失败:(0)
这是我的update.php代码:
<?php
// Create connection
$con=mysqli_connect("xxx","xxx","xxx","xxx");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$id = $_GET['id'];
$result = mysqli_query($con, "SELECT * FROM characters WHERE id = '$id'");
$row=mysqli_fetch_array($result, MYSQLI_ASSOC);
?>

我是PHP的新手,所以我不太确定这里有什么问题。谢谢你的帮助!

查看您传递给bind_param()
的值与prepare()
中的问号。我可以一眼看出$id
在错误的地方。错误消息表明计数也是错误的。
<?php
// Your database info
$db_host = 'xxx';
$db_user = 'xxx';
$db_pass = 'xxx';
$db_name = 'xxx';
try {
$conn = new PDO("mysql:host=$db_host;dbname=$db_name", $db_user, $db_pass);
} catch(PDOException $e) {
echo $e->getMessage();
exit;
}
$expected_posts = array(
"id", "name", "picture", "breed", "gender", "height", "age", "sire", "dam", "children",
"status", "player", "bodytype", "genetics", "basecolor", "eyes", "mane", "tail", "patterns",
"face", "legs", "bodymark", "extras", "trait1", "trait2", "trait3", "trait4", "trait5",
"trait6", "defect1", "defect2", "defect3", "defect4", "defect5", "defect6", "notes"
);
$posts = array();
foreach ($_POST as $k=>$v) {
if (in_array($k, $expected_posts)) {
$posts[$k] = trim($v);
}
}
$sql = "UPDATE characters SET name=:name, picture=:picture, breed=:breed, gender=:gender, height=:height,
age=:age, sire=:sire, dam=:dam, children=:children, status=:status, player=:player, bodytype=:bodytype,
genetics=:genetics, basecolor=:basecolor, eyes=:eyes, mane=:mane, tail=:tail, patterns=:patterns,
face=:face, legs=:legs, bodymark=:bodymark, extras=:extras, trait1=:trait1, trait2=:trait2,

defect3=:defect3, defect4=:defect4, defect5=:defect5, defect6=:defect6, notes=:notes WHERE id=:id";
$stmt = $conn->prepare($sql);
$stmt->execute($posts);
?>
答案 1 :(得分:0)
$result->bind_param('sssssssssssssssssssssssssssssssssssi', $name, $picture, $breed,
$gender, $height, $age, $sire, $dam, $children, $status, $player, $bodytype, $genetics,
$basecolor, $eyes, $mane, $tail, $patterns, $face, $legs, $bodymark, $extras, $trait1,
$trait2, $trait3, $trait4, $trait5, $trait6, $defect1, $defect2, $defect3, $defect4,
$defect5, $defect6, $notes, $id)
对于要绑定的每个字符串,添加s
,对于每个整数,您应添加i
。我不确定我的类型是否正确检查它们并修改任何s
到i
,如果它实际上是您正在更新的整数。
