Question

我这里有一个使用php的购物车样本。我试着将它修改为我需要的东西。我在这里添加的是使用ajax / jquery的搜索功能。搜索引擎工作，但问题是添加按钮不起作用。为什么我无法在列表中添加项目？我在这里做的是将index.php中的表分成search.php，所以当我尝试只搜索项目时我需要在表格中显示的内容。任何帮助都会受到欢迎。

的search.php

<?php
session_start();
include_once("config.php");
    //current URL of the Page. cart_update.php redirects back to this URL
$current_url = base64_encode($url="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
if(isset($_POST['bid'])) {
$search = $mysqli->real_escape_string($_POST['bid']);
$search = preg_replace("/[^A-Za-z0-9 ]/", '', $search);
$search = $_POST['bid'];

    $results = $mysqli->query("SELECT * from app WHERE item_name LIKE '%$search%' ORDER BY item_name ASC");
        echo'<table id="tfhover" cellspacing="0" class="table-list" style="text-transform:uppercase;" border="1">
        <thead>
            <tr>
        <th></th>
            </tr>
        </thead>';
        echo'<tbody>';
if(($results->num_rows)>= 1){
        while($obj = $results->fetch_object())
        {
            echo '<form method="post" action="cart_update.php">';
            echo '<tr>
                    <td style="text-align:left;">'.$obj->item_name.'</td>
                    <td><button class="add_to_cart" style="font-size:9px;">Add</button></td>
                </tr>';
            echo '<input type="hidden" name="product_code" value="'.$obj->counter.'" />';
            echo '<input type="hidden" name="type" value="add" />';
            echo '<input type="hidden" name="return_url" value="'.$current_url.'" />';
            echo '</form>';
        }
    echo "</tbody></table>";
    }
if(($results->num_rows)<= 0){
echo '<div style="margin-left:360px;">No Results</div>';
}
}
?>

的index.php

<?php
session_start();
include_once("config.php");
    //current URL of the Page. cart_update.php redirects back to this URL
$current_url = base64_encode($url="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
?>
    <input type="text" name="bid" id="bid" placeholder="Search" style="text-transform:uppercase;width:300px;text-align:center;"/>
<div id="bid_result"></div>
    <script type="text/javascript">
$(document).ready(function () {
    function load(query) {
        $.post('search.php', {
            bid: query
        }, function (search_bid) {
            $('#bid_result').stop(true, true).fadeIn(200).html(search_bid);
        }); //End ajax call
    }

    load($("#bid").val());
    //Live search
    $("#bid").on('keyup', function () {
        //Input field value
        load($(this).val());
    }); //End on function
}); //End document.ready state
</script>

Cart_update.php

这是我的完整代码cart_update.php http://pastebin.com/1iDENLa0

<?php
session_start();
include_once("config.php");
if(isset($_POST["type"]) && $_POST["type"]=='add')
{
$product_code   = filter_var($_POST["product_code"], FILTER_SANITIZE_STRING); // product code
$return_url     = base64_decode($_POST["return_url"]); //return url
}
?>

好的，我更改了代码的某些部分，你可以查看这段代码吗？它应该提交。

<?php
    echo '
    <table id="tfhover" cellspacing="0" class="table-list" style="text-transform:uppercase;" border="1">
     <thead>
      <tr>
       <th></th>
      </tr>
     </thead>
    <tbody>
     <tr>
      <td>';
    if(($results->num_rows)>= 1) {
       while($obj = $results->fetch_object()) {
          echo '
                <form method="post" action="cart_update.php">
                 <input type="hidden" name="product_code" value="'.$obj->counter.'" />
                 <input type="hidden" name="type" value="add" />
                 <input type="hidden" name="return_url" value="'.$current_url.'" />
                 <input type="submit" class="add_to_cart" value="Add" style="font-size:9px;"/>
                </form>';
       }
       echo '</tr></td>';
    }
    echo "</tbody></table>";
?>
