Question

我正在尝试管理面板。我用PDO进行数据库连接。在面板中，我想更新网站标题，网站网址等。但我有一个问题。我确信我做的都是真的。

我需要你的帮助。

这是管理员代码：

<script>
var a = false;
function toggleBold(){
    a = !a;
    if(a){
        document.getElementById("entertext").style.fontWeight=700;
    }
    else{
        document.getElementById("entertext").style.fontWeight=200;
    }
}

var b = false;
function toggleitalic(){
    b = !b;
    if(b){
        document.getElementById("entertext").style.fontStyle="italic";
    }
    else {
        document.getElementById("entertext").style.fontStyle="normal";
    }
}

var c = false;
function toggleline() {
    c =!c;
    if(c){             
       document.getElementById("entertext").style.textDecoration="underline";
    }
    else {
        document.getElementById("entertext").style.textDecoration="none";
    }
}


var r = false;
function togglered() {
    console.log("clicked");
    r=!r;
    if(r){
        document.getElementById("entertext").style.color="red";
    }
    else{
        document.getElementById("entertext").style.color="black";
    }
}

var b = false;
function toggleblue() {
    console.log("clicked");

    b=!b;
    if(b){
        document.getElementById("entertext").style.color="blue";
    }
    else{
        document.getElementById("entertext").style.color="black";
    }
}

var g = false;
function togglegreen() {
    g=!g;
    if(g){
        document.getElementById("entertext").style.color="green";
    }
    else{
        document.getElementById("entertext").style.color="black";
    }
}

var imp = false;
function togglefontA(){
    imp = !imp;
    if(imp){
        document.getElementById("entertext").style.fontFamily= "Impact,Charcoal,sans-serif";
    }
}


var tim = false;
function togglebfontB(){
    tim=!tim;
    if(tim){
        document.getElementById("entertext").style.fontFamily = "Times New Roman, Times, serif";
    }
}

var age = false;
function togglefontC(){
    age=!age;
    if(age){
        document.getElementById("entertext").style.fontFamily = "Agency FB, verdana, helvetica, sans-serif";
    }
}

var nor = false;
function togglefontD(){
    nor=!nor;
    if(nor){
        document.getElementById("entertext").style.fontFamily = "Arial, Helvetica, sans-serif";
    }
}


function rgb(){
    if(check()){
        document.getElementById("entertext").style.backgroundColor =
            "rgb("+document.getElementById("red").value+","
            + document.getElementById("green").value+","
            + document.getElementById("blue").value+")";
    }
    else{
        document.getElementById("entertext").style.backgroundColor = "white";
    }
}

function check(){
    var red= document.getElementById("red").value;
    var green= document.getElementById("green").value;
    var blue= document.getElementById("blue").value;
    return red <= 255 && red >= 0 && green <= 255 && green >= 0 && blue <=    255 && blue >= 0; 
}

   </script>

这是islem.php：

   <?php
include 'config.php';
$ayarsor=$db->prepare("select * from ayar1 where ayar_id=?");
$ayarsor->execute(array(0));
$ayarcek=$ayarsor->fetch(PDO::FETCH_ASSOC);

?>
<html>
<head>
 <link rel="stylesheet" type="text/css" href="style.css" />
<title></title>
</head>
<body>
<div class="ust">
<h1><center>panel</center></h1>
</div>
<div class="container">
<h2>Send something</h2>
<p>  ADMİN PANELİ</p>
</div>
<div class="orta">
<table>
    <form action="islem.php" method="POST">
      <tr>
            <td><label>Site başlığı</label></td>
            <td><input type="text" name="ayar_title" /></td>
        </tr>
        <tr>
            <td><label>Duyuru</label></td>
            <td><input type="text" name="ayar_duyuru" value="<?php echo $ayarcek['ayar_duyuru']; ?>" /></td>
        </tr>
        <tr>
            <td><label>Düşman</label></td>
            <td><input type="text" name="ayar_dusman" /></td>
        </tr>
        <tr>
            <td></td>
            <td><button name="genelayarkaydet">Güncelle</button></td>
        </tr>
    </form>
</table>``

</div>

您需要绑定数据库查询的变量。

$ayarkaydet = $db->prepare("UPDATE ayar1 set ayar_title = :sitetitle,
                            ayar_duyuru = :duyuru,
                            ayar_dusman = :dusman 
                            WHERE ayar_id = 0");

$update = $ayarkaydet->execute(array(
    'sitetitle' => $_POST['ayar_title'],
    'duyuru' => $_POST['ayar_duyuru'],
    'dusman' => $_POST['ayar_dusman']
));

PHP PDO - 我无法更新变量
