OpenCart product_form html-select 不会将值传递给数据库答案

【问题标题】：OpenCart product_form html-select won't pass the value to the databaseOpenCart product_form html-select 不会将值传递给数据库

【问题描述】：

我似乎找不到我做错了什么

<pre>
<?php
print_r($_POST); echo $parcel_type; 
?>
</pre>

打印给出：array() $parcel_type 给出：0

保存时不会传递选择值。其他 opencart 选择框的编码似乎相同，但确实传递了值。

有人知道我哪里出错了吗？

【问题讨论】：

点击添加到购物车按钮时触发的javascript函数怎么样？可以发一下吗？
它与添加到购物车按钮无关。此功能已添加到产品页面 (product_form) 的管理端。还添加了一些工作正常的复选框。只有选择框没有。这是用于其他 html 选择框的所有代码的精确副本。我在管理 product_form 页面中找不到任何 java 或 JQuiry。数据库字段 (parcel_type) 已添加到模型中。我以为我错过了 JQuiry 或其他东西，但我在产品表单中的其他 html 选择中找不到它。
如果您在点击提交时查看浏览器的开发者工具中的网络活动，您是否看到正在发送的值？
-----WebKitFormBoundarybU8ytNpb78nsswIE Content-Disposition: form-data; name="parcel_type" 6 发送。基值为 0 我检查了数据库。不用找了。前端没有变化。对于需要知道如何找到 $_post 值的任何人，请检查此网址 stackoverflow.com/questions/15603561/…
如果我删除 product.php 中的 (isset()) ，则会出现未定义索引 parcel_type 错误。我检查了数据库.. parcel_type 在那里。检查模型是否有错字。非。 paorduct_form.tpl 中的选择值在那里。所以这应该只在控制器 product.php 中留下一个错误。我检查了产品的数组 'parcel_type' => $result['parcel_type'],

【解决方案1】：

到目前为止，我在 product_form.tpl 中使用它

<?php
$parcel_option = array(
''  => 'Kies verzendvorm',
'0' => 'pakket' ,
'1' => 'brievenbuspakket',
'2' => 'brievenbuspakje <20gr',
'3' => 'brievenbuspakje <50gr', 
'4' => 'brievenbuspakje <100gr',
'5' => 'brievenbuspakje <250gr',
'6' => 'brievenbuspakje <2 KG',   
);

?>
<div class="form-group">
<label class="col-sm-2 control-label" for="input-parcel-type"><span data-toggle="tooltip" title="Kies verzendvorm"</span> 
<?php echo $entry_parcel_type; ?></label>
<div class="col-sm-10">
<select name="parcel_type" id="input-parcel-type" class="form-control">
<?php       

if (isset($data['parcel_type'])) { 
?>
<option value="<?php '.$parcel_type.'?>" ><?php echo  $parcel_type; ?></option>

<?php
foreach($parcel_option as $parcel_type => $parcel_text):
echo '<option value="'.$parcel_type.'">'.$parcel_text.'</option>'; 
endforeach;
?>

<?php } else { ?>
<option value="0" selected="selected"> Geen selectie - Standaard pakketkosten</option>
<?php }  ?>
</select>
</div>
</div>

我唯一不知道的是如何链接此代码

<option value="<?php '.$parcel_type.'?>" ><?php echo  $parcel_type; ?>

到数组，因此它显示属于 Parcel_type 的宗地文本。
