Question

我一直盯着这个页面待了一个多小时。我的更新功能似乎没有更新。当我通过SQL尝试它似乎没问题。我在此页面底部有一个表单，用于更新表格中的字段。谁能发现错误？

   <?php

// First of all initialise the user and check for permissions
require_once "/var/www/users/user.php";
$user = new CHUser(2);

// And create a cid object
    require_once "/var/www/Testing/DisplayWIPOnLocation.php";
$BundleProgress= new CHWIPProgress();


 if(isset($_GET['Reference'])){

 $todays_date = date("Y-m-d H:i:s");
 $content .= " <h3> Details for Bundle : $reference </h3> ";
 $bundle = $BundleProgress->GetBundle($_GET['Reference']);   
 $reference = $_GET['Reference'];

 // Now show the details

    foreach($bundle as $x){
        $content .= "

功能

    public function UpdateReason($reason, $bundlereference) {
                    $sql = "UPDATE `ArchiveBundle`
                                    SET `Issue` = " . $reason . "
                                    WHERE `BundleReference` = " . $bundlereference .    
                ";";
                    mysql_select_db(DB_DATABASE_NAME, $this->conn);
                    return mysql_query($sql, $this->conn);
            }

Answer 1

变化：

if($_GET['step'] == 2)

为：

if((int)$_GET['step'] === 2)

和

public function UpdateReason($reason, $bundlereference) {
    $sql = "UPDATE `ArchiveBundle`
        SET `Issue` = " . $reason . "
        WHERE `BundleReference` = " . $bundlereference .    
        ";";
    mysql_select_db(DB_DATABASE_NAME, $this->conn);
    return mysql_query($sql, $this->conn);
}

为：

public function UpdateReason($reason, $bundlereference) {
    mysql_select_db(DB_DATABASE_NAME, $this->conn);

    $_reason = mysql_real_escape_string($reason,$this->conn);
    $_bundlereference = mysql_real_escape_string($bundlereference,$this->conn);

    $sql = "UPDATE `ArchiveBundle`
            SET `Issue` = '" . $_reason . "'
            WHERE `BundleReference` = '" . $_bundlereference . "'";

    return mysql_query($sql, $this->conn);
}

试试吧。代码尚未经过测试，但它是一个很好的起点。

要尝试调试此处发生的事情，请执行以下操作：

public function UpdateReason($reason, $bundlereference) {
    error_reporting(E_ALL ^ E_NOTICE);

    $db_selected = mysql_select_db(DB_DATABASE_NAME, $this->conn);

    if (!$db_selected) {
        die("Can't use db : " . mysql_error());
    }

    $_reason = mysql_real_escape_string($reason,$this->conn);
    $_bundlereference = mysql_real_escape_string($bundlereference,$this->conn);

    $sql = "UPDATE `ArchiveBundle`
            SET `Issue` = '" . $_reason . "'
            WHERE `BundleReference` = '" . $_bundlereference . "'";

    mysql_query($sql, $this->conn);

    die(mysql_error());
}

此外，在您提交表单时，您似乎没有传入Reference参数，因此当您发布表单时，if（isset（$ _ GET ['Reference']））将失败。我已经更改了下面的表格和表单代码以使其更具可读性，在表单提交时传递Reference参数，并在获取数据集之前更新db记录，以便您在返回的表中看到更新的记录。 / p>

我可以建议您首先检查mysql_query返回的内容。也许这个特定的变量定义不正确。另请记住在查询中添加引号。

我在这做错了什么？
