Question

我有一个对象数组，我想插入数据库所以我用for循环遍历所有对象。

我正在发送带有ajax的$offer和$gameid $offer是包含10个项目的数组，$gameid只是integer

所有变量都有数据，因为它们是echo。

我正在使用localhost

开发xampp

include "../../inc/connect.php";

$offer = @$_POST['offer'];
$gameid = @$_POST['gameid'];

$query = $db->prepare("INSERT INTO items VALUES (id, gameid, assetid, name, icon, price, owner)");

for($i = 0; $i < count($offer) - 1; $i++) {
    $assetid = $offer[$i]['assetid'];
    $name = $offer[$i]['name'];
    $icon = $offer[$i]['icon'];
    $price = $offer[$i]['price'];

    $query_array = array('id' => '', 'gameid' => $gameid, 'assetid' => $assetid, 'name' => $name, 'icon' => $icon, 'price' => $price, 'owner' => $steamid);

    $query->execute($query_array);

echo "
<div class='item'>
    <div class='left'>
        <img src='$avatar' />
        <div class='names'>
            <p>$username</p>
            <p>$name</p>
        </div>
    </div>
    <div class='right'>
        <div class='price'>
            $" . $price . "
        </div>
        <div class='item-icon'>
            <img src='http://cdn.steamcommunity.com/economy/image/$icon' />
        </div>
    </div>
</div>  
";
}

连接

$user = "root";
$pass = "";

$db = new PDO('mysql:host=localhost;dbname=website', $user, $pass);

表

$query->execute($query_array)

时得到的结果

mysql_error.log或ajax数据中没有错误

Answer 1

您的占位符需要冒号，否则它会将值视为列名：

$query = $db->prepare("INSERT INTO items VALUES (:id, :gameid, :assetid, :name, :icon, :price, :owner)");

$query_array = array(':id' => '', ':gameid' => $gameid, ':assetid' => $assetid, ':name' => $name, ':icon' => $icon, ':price' => $price, ':owner' => $steamid);

问题在于您的查询。它应该是这样的：

'use strict';
var page = require('webpage').create(),
    system = require('system'),
    address, output, pixelRatio, width, height;
page.cookiesEnabled = true;

//i have added some of the cookies here which my page requires to load

var args = Array.prototype.slice.call(system.args, 1);

address = 'myurl';
output = 'd:/screenshots/11.png';
pixelRatio = 2;

page.onConsoleMessage = function(msg) {
    console.log(msg);
};

// Here we block the first (few) requests until we have set the correct window variables
var resources = [];
page.onResourceRequested = function(requestData, networkRequest) {
    if((requestData.url.match(/\.js/g) !== null || requestData.url.match(/\/js\//g) !== null)) {
        if(requestData.url.match(/_phantomLoadMe/g) === null && requestData.url.match(/typekit/gi) === null) {
            console.log('Temporarily blocking too soon request to ', requestData['url']);
            resources.push(requestData['url']);
            networkRequest.abort();
        }
    }

    var reqUrl = requestData.url;
    var newUrl = requestData.url.split(',%20')[0];

    if (newUrl != reqUrl) {
      networkRequest.changeUrl(newUrl);
    }
};

width = (1440*pixelRatio);
height = (900*pixelRatio);

page.viewportSize = { width: width, height: height };
page.settings.localToRemoteUrlAccessEnabled = true;
page.settings.userAgent = 'Chrome/55.0.2883.87 Mozilla/5.0 (Windows NT 5.1; rv:8.0) Gecko/20100101 Firefox/7.0';

page.open(address, function (status) {
    if (status !== 'success') {
        console.log('Unable to load the address!', address, status);
        phantom.exit();
    } else {
        // Manipulate the DOM
        page.evaluate(function (r, urls, width, height) {
            console.log('Setting window.devicePixelRatio to ' + r);
            window.devicePixelRatio = r;
            window.onload = false;
            window.innerWidth = (width/r);
            window.innerHeight = (height/r);
            document.documentElement.offsetWidth = (document.documentElement.offsetWidth/r);
            document.documentElement.offsetHeight = (document.documentElement.offsetHeight/r);
            document.documentElement.clientWidth = (document.documentElement.clientWidth/r);
            document.documentElement.clientHeight = (document.documentElement.clientHeight/r);
            screen.width = width;
            screen.height = height;
            document.body.style.webkitTransform = "scale(" + r + ")";
            document.body.style.webkitTransformOrigin = "0% 0%";
            document.body.style.width = (100 / r) + "%";

            // Now that we've set our window, let's get those scripts again
            var _phantomReexecute = [];
            var _phantomScripts = document.getElementsByTagName("script");
            _phantomScripts = Array.prototype.slice.call(_phantomScripts);
            if(_phantomScripts.length > 0) {
                _phantomScripts.forEach(function(v) {
                    if('src' in v && v.src !== "" && v.src.match(/typekit/gi) === null) {
                        urls.push(v.src);
                    }
                    else {
                        _phantomReexecute.push({'script': v.innerHTML});
                    }
                });
            }
            var _phantomAll = document.getElementsByTagName("script");
            for (var _phantomIndex = _phantomAll.length - 1; _phantomIndex >= 0; _phantomIndex--) {
                if(_phantomAll[_phantomIndex].src.match(/typekit/gi) === null) {
                    _phantomAll[_phantomIndex].parentNode.removeChild(_phantomAll[_phantomIndex]);
                }
            }
            var _phantomHead = document.getElementsByTagName("head")[0];
            if(urls.length > 0) {
                urls.forEach(function(u) {
                    var _phantomScript = document.createElement("script");
                    _phantomScript.type = "text/javascript";
                    _phantomScript.src = u + '?_phantomLoadMe';
                    _phantomHead.appendChild(_phantomScript);
                });
            }
            if(_phantomReexecute.length > 0) {
                _phantomReexecute.forEach(function(s) {
                    var _phantomScript = document.createElement("script");
                    _phantomScript.type = "text/javascript";
                    _phantomScript.innerHTML = s.script;
                    _phantomHead.appendChild(_phantomScript); 
                });
            }

            // Make sure to execute onload scripts
            var _phantomCount = 0;
            var _phantomIntVal = setInterval(function() {
                if(window.onload !== false && window.onload !== null) {
                    window.onload();
                    clearInterval(_phantomIntVal);
                }
                _phantomCount++;

                if(_phantomCount > 10) {
                    clearInterval(_phantomIntVal);
                }
            }, 100);
        }, pixelRatio, resources, width, height);

        // Make the screenshot
        window.setTimeout(function () {
            page.render(output);
            page.release();
            phantom.exit();
        }, 500000);
    }
