Prestashop 1.6.1助手表单字段未定义索引

我为此挣扎了好几个小时： 我正在尝试为自定义模块在Prestashop中使用HelpPerform类生成的表单添加新字段

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

我尝试在

getContent（）

函数中对模块的配置页面执行此操作

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

以下字段已被接受且有效：

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

它给出了以下错误：

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

Notice on line 387 in file D:\wamp\www\qmart.ro\tools\smarty\sysplugins\smarty_internal_templatebase.php(157) : eval()'d code
[8] Undefined index: CROSSSELLING_NBR

但是，仍然会生成输入，如下所示：

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

array(
    'type' => 'text',
    'label' => $this->l('Number of displayed products'),
    'name' => 'CROSSSELLING_NBR',
    'desc' => $this->l('Set the number of products displayed in this block.'
)

<input type="text" name="CROSSSELLING_NBR" id="CROSSSELLING_NBR" value="" class="">

我尝试的是：

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

• 例如，将输入类型从文本更改为颜色，会产生相同的错误
• 更改标签内容和名称内容时，仍会出现错误

我没有更改核心文件中的任何内容

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

因此，正在为这些输入构建表单，但这种“未定义索引”的情况仍然存在。

因此，它们显然迫使您为输入选择一些默认值

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

我通过添加以下行解决了此问题：

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

$helper->fields_value['CROSSSELLING_NBR'] = '';

根据你的密码

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

array(
    'type' => 'text',
    'label' => $this->l('Number of displayed products'),
    'name' => 'CROSSSELLING_NBR',
    'desc' => $this->l('Set the number of products displayed in this block.'
)

“desc”中有错误，需要关闭最后一个括号，这应该可以

array(
    'type' => 'file',
    'label' => $this->l('Button image'),
    'id' => 'button_image_path',
    'name' => 'button_image_path',
    'image' => '<img src="'._MODULE_DIR_.$this->name.'\\img\\'.basename($buttonImage["setting_value"]).'" class="button-image-preview" width="30">'
)

array(
    'type' => 'text',
    'label' => $this->l('Number of displayed products'),
    'name' => 'CROSSSELLING_NBR',
    'desc' => $this->l('Set the number of products displayed in this block.')
)

另见下文评论。
