问题描述
我正在尝试在自定义woocommerce页面中添加文件上传以及广播输入；所有产品都在列表视图中显示的位置.
I am trying to add a file upload along with radio inputs in a custom woocommerce page; where all the products are showing in a list view.
自定义页面代码:
<?php /*

<th></th>

'orderby' => 'post__in',
//'order' => 'DESC',

$wp_query = new WP_Query( $args );

只有某些用户可以访问此页面，因此与单个产品页面对应的页面相比，它具有不同的输入字段，价格.客户不希望刷新此页面，因此，在我所掌握的知识很少的情况下，我不得不添加 AJAX .现在情况变得越来越复杂，请帮帮我.
This page is only accessible to certain users, so it has different input fields, price than the single product page counterpart. Client don't like this page to be refreshed so I had to add AJAX, with the little knowledge I have. Now it's getting more complicated so please help me out.

In your actual code, there is many mistakes as:
- 使用相同钩子的重复钩子函数，需要将其合并.
- 不建议使用的钩子函数.
- 没有用处或不需要的挂钩函数.
- 与文件上传相关的代码错误或缺少代码
- Repetitive hooked functions using the same hook, that need to be merged instead.
- Deprecated hooked functions.
- Not useful or not needed hooked functions.
- Wrong or missing code related to file upload
这是您重新访问的代码(更加轻巧，紧凑和完整):
Here is your revisited code (much more lighter, compact and complete):
// Display additional product fields (+ jQuery code)
add_action( 'woocommerce_before_add_to_cart_button', 'display_additional_product_fields', 9 );
function display_additional_product_fields(){
// Array of radio button options
$options = array( __("Front Side"), __("Back Side"), __("Both Sides") );
// Temporary styles
?>
<style>
.upload-logo a.button { padding: .3em .75em !important; }
.upload-logo a.button.on { background-color: #CC0000 !important; color: #FFFFFF !important; }
.upload-logo p span { display:inline-block; padding:0 8px 0 4px; }
</style><?php
// Html output ?>
<div class="upload-logo">
<p><strong><?php _e( "Add a Logo option"); ?>: </strong>
<a href="#" class="button"><?php _e( "Yes" ); ?></a>
<input type="hidden" name="upload_active" value="">
</p>
<div id="hidden-inputs" style="display:none">
<p><label for="radio_field"><?php
echo __( "Where you want the logo?" ) . ' <br>';
// Loop though each $options array
foreach( $options as $key => $option ) {
$atts = $key == 0 ? 'name="side_field" checked="checked"' : 'name="side_field"'; ?>
<input type="radio" <?php echo $atts; ?> value="<?php echo $option; ?>"><span> <?php echo $option . '</span> ';
}
?>
</label></p>
<p><label for="file_field"><?php echo __("Upload logo") . ': '; ?>
<input type='file' name='image' accept='image/*'>
