我正在使用cordova和jquery移动项目.

我已经能够使用文件传输插件上传一个图像.现在我尝试上传2或3张图片.

这是html代码:

<label for="image">Pictures:</label>
<a href="" id="image1Button" class="ui-btn" onclick="getPhoto(pictureSource.PHOTOLIBRARY);">Get first picture</a><br>
<a href="" id="image2Button" class="ui-btn" onclick="getPhoto(pictureSource.PHOTOLIBRARY);" style="display:none;">Get second picture</a><br>
<a href="" id="image3Button" class="ui-btn" onclick="getPhoto(pictureSource.PHOTOLIBRARY);" style="display:none;">Get third picture</a><br>
<img id="image1" style="display:none;width:25%;">
<img id="image2" style="display:none;width:25%;">
<img id="image3" style="display:none;width:25%;">
<label for="title">Title</label>
<input data-clear-btn="true" name="title" id="title" value="" type="text">
<input value="Continue" type="submit" id="adButton">

这是jquery代码:

multi_upload(user_id);

function multi_upload(user_id) {

    var image1 = "image1";
    var image2 = "image2";
    var image3 = "image3";
    if($('#image2').prop('src') == ''){
        // upload one file
        upload(user_id, image1, "true");
    }
    if($('#image3').prop('src') == ''){ …

我从事cordova jquery 移动项目。

我想知道是否可以在触发 switchToLocationSettings() 函数后进行回调。

我想知道用户是否在他的设备上启用了 GPS。

我像这样使用它：

cordova.plugins.diagnostic.switchToLocationSettings();

但我想要这样的东西：

cordova.plugins.diagnostic.switchToLocationSettings(Success,Error);

是否可以？

我试图弄清楚如何将属性传递到 Wordpress 中基于 react 的插件中（使用 @wordpress/scripts）。

我的 main.php 文件：

<?php
defined( 'ABSPATH' ) or die( 'Direct script access disallowed.' );

define( 'ERW_WIDGET_PATH', plugin_dir_path( __FILE__ ) . '/widget' );
define( 'ERW_ASSET_MANIFEST', ERW_WIDGET_PATH . '/build/asset-manifest.json' );
define( 'ERW_INCLUDES', plugin_dir_path( __FILE__ ) . '/includes' );

add_shortcode( 'my_app', 'my_app' );
/**
 * Registers a shortcode that simply displays a placeholder for our React App.
 */
function my_app( $atts = array(), $content = null , $tag = 'my_app' ){
    ob_start();
    ?>
        <div id="app">Loading...</div>
        <?php wp_enqueue_script( …

我尝试使用查询来查找此查询的用户:

                Select id, username, lat, long,
                    acos(sin(0.761312289853)*sin(radians(lat)) + cos(0.761312289853)*cos(radians(lat))*cos(radians(long)-0.0676354285243)) * 6371 As D
                From (
                    Select id, username, lat, long,
                    From rcp_users
                    Where lat Between 43.4491099949 And 43.7908522051
                      And long Between 3.63919239657 And 4.11125680343
                ) As FirstCut
                Where acos(sin(0.761312289853)*sin(radians(lat)) + cos(0.761312289853)*cos(radians(lat))*cos(radians(long)-0.0676354285243)) * 6371 < 30
                Order by D

但我有这个错误:
