我有一个前端用户配置文件模板，我正在工作，一切都很好，除了上传配置文件图片。我创建了一个自定义用户字段，我正在尝试使用按钮文件类型上载图片并将URL存储在自定义字段中。

看一看-https://pastebin.com/rPErwCgU

我目前已经在使用此代码进行前端帖子上传，它允许多张图片。我需要找出如何为只有1张照片的用户执行此操作，并将其存储在附加到当前用户的自定义字段中--

if (!empty($_FILES[\'sightMulti\'][\'tmp_name\'][0])) {
    $i = 1;
    $files = $_FILES[\'sightMulti\'];
    foreach ($files[\'name\'] as $key => $value) {
        if ($files[\'name\'][$key]) {
            $file = array(
                \'name\' => $files[\'name\'][$key],
                \'type\' => $files[\'type\'][$key],
                \'tmp_name\' => $files[\'tmp_name\'][$key],
                \'error\' => $files[\'error\'][$key],
                \'size\' => $files[\'size\'][$key]
            );
            $_FILES = array("sight" . $i => $file);
            $newuploadMulti = sight("sight" . $i, $pid);
            if ($i == 1) {
                update_post_meta($pid, \'_thumbnail_id\', $newuploadMulti);
            }
            add_post_meta($pid, \'imic_property_sights\', $newuploadMulti, false);
        }
        $i++;
    }
}

表单中的字段--

<div class="col-md-12 col-sm-12">
        <label><?php _e(\'Upload Images\', \'framework\'); ?></label>
        <p><?php _e(\'Upload images that are best clicked for better appearance of your property\', \'framework\'); ?></p> 
</div>
<div class="row" id="multiplePhotos" style="margin-top:15px;">
    <div class="col-md-12 col-sm-12">
        <?php
        echo\'<div class="image-placeholder" id="photoList">\';
        if (!empty($property_sights_value)) {
            foreach ($property_sights_value as $property_sights) {
                $default_featured_image = get_post_meta($Property_Id, \'_thumbnail_id\', true);
                if ($default_featured_image == $property_sights) {
                    $def_class = \'default-feat-image\';
                } else {
                    $def_class = \'\';
                }
                echo \'<div class="col-md-2 col-sm-2">\';
                echo \'<div id="property-img"><div id="property-thumb" class="\' . $def_class . \'"><a id="feat-image" class="accent-color default-image" data-original-title="Set as default image" data-toggle="tooltip" style="text-decoration:none;" href="#"><div class="property-details" style="display:none;"><span class="property-id">\' . $Property_Id . \'</span><span class="thumb-id">\' . $property_sights . \'</span></div><img src="\' . wp_get_attachment_thumb_url($property_sights) . \'" class="image-placeholder" id="filePhoto2" alt=""/></a>\';
                if (get_query_var(\'site\')) {
                    echo \'<input rel="\' . $Property_Id . \'" type="button" id="\' . $property_sights . \'" value="Remove" class="btn btn-sm btn-default remove-image">\';
                }
                echo \'</div></div>\';
                echo \'</div>\';
            }
        }
        echo \'</div>\';
        ?>
        <input id="filePhotoMulti" type="file" name="sightMulti[]" multiple onChange="previewMultiPhotos();">
    </div>
</div>

UPDATE

这是我的右上方的字段，其他字段可以保存罚款-

if ( !empty( $_POST[\'agent-image\'] ) )
update_user_meta( $current_user->ID, \'agent_image\', esc_attr( $_POST[\'agent-image\'] ) );

if(!empty($_FILES)) {
$uploaddir = wp_upload_dir();

$file = $_FILES[agent-image];

$uploadfile = $uploaddir[\'path\'] . \'/\' . basename( $file[\'name\'] );

move_uploaded_file( $file[\'tmp_name\'] , $uploadfile );

$filename = basename( $uploadfile );

$wp_filetype = wp_check_filetype(basename($filename), null );

$attachment = array(
    \'post_mime_type\' => $wp_filetype[\'type\'],
    \'post_title\'     => preg_replace(\'/\\.[^.]+$/\', \'\', $filename),
);

$attach_id = wp_insert_attachment( $attachment, $uploadfile );
}

我的输入字段--

<input type="file" name="agent-image">

我是如何在作者身上使用它的。php模板--

<?php 
$author_pic = get_the_author_meta(\'agent-image\', $user->ID);
echo \'<div><img src="\'. $author_pic .\'" alt="\'. $userName .\'" class="img-thumbnail authppic"></div>\'; ?>

UPDATE 2

代码现在导致该页面出现HTTP 500错误--

if ( !empty( $_FILES[agent-image][name] )) {
$uploaddir = wp_upload_dir();

$file = $_FILES[agent-image];

$uploadfile = $uploaddir[\'path\'] . \'/\' . basename( $file[\'name\'] );

move_uploaded_file( $file[\'tmp_name\'] , $uploadfile );

$filename = basename( $uploadfile );

$wp_filetype = wp_check_filetype(basename($filename), null );

$attachment = array(
    \'post_mime_type\' => $wp_filetype[\'type\'],
    \'post_title\'     => preg_replace(\'/\\.[^.]+$/\', \'\', $filename),
);

$attach_id = wp_insert_attachment( $attachment, $uploadfile );
update_user_meta( $current_user->ID, \'agent_image\', $attach_id ));
}

                } else {

                    $attachment = array(
                        \'post_mime_type\' => $file_return[\'type\'],
                        \'post_title\'     => preg_replace( \'/\\.[^.]+$/\', \'\', basename( $filename ) ),

                    // Generate the metadata for the attachment, and update the database record.
                    $attachment_data = wp_generate_attachment_metadata( $attachment_id, $filename );
                    wp_update_attachment_metadata( $attachment_id, $attachment_data );

                    update_user_meta( $current_user->ID, \'agent_image\', $attachment_id ));

                }

            }
