php - 如何在 wp bakery 中返回 vc_link

Question

我正在尝试在 wpbakery 构建器中创建自定义元素，我在其中添加文本字段、图像和 url。Evrything 工作正常，只是 url 中有一个问题。谁能帮我解决这个问题。

下面是我正在尝试的代码：

add_shortcode( 'expert', 'expert_func' );
function expert_func( $atts, $content = null ) { // New function parameter $content is added!
extract(
    shortcode_atts(
      array(
        'expert_image' => 'expert_image',
        'title'   => '',
      ),
      $atts
    )
  );

  $img_url = wp_get_attachment_image_src( $expert_image, "full");

  extract(
    shortcode_atts(
      array(
        'expert_exp_image' => 'expert_exp_image',
        'title'   => '',
      ),
      $atts
    )
  );

  $exp_img_url = wp_get_attachment_image_src( $expert_exp_image, "full");



$result .='<div class="inner__card">
            <div class="expert-img">
              <img src="'. $img_url[0] .'">
            </div>
            <div class="expert-details">
              <p class="name">'.$atts['expert_name'].'</p>
              <p class="designation">'.$atts['expert_designation'].'</p>
              <div class="expect-experience">
                <div class="expect-experience-no">
                  <img src="'. $exp_img_url[0] .'" alt="experience-10">
                </div>
                <div class="expect-experience-text">
                  <p>'.$atts['expert_short_desc'].'</span></p>
                </div>
              </div>
              <p class="details">'.$atts['expert_description'].'</p>
              <div class="expert-btn">';
if( !empty($url) ){
      $column_link_array = vc_build_link($url);
      $url = $column_link_array['url'];
      $result .= "<a href='$url' class='learn-btn'></a>";
  }
$result .=' </div>
            </div>
        </div>';

 //$result = $button;

 //print_r($atts);

 return $result;

 }

 //backend
 add_action( 'vc_before_init', 'expert_integrateWithVC' );
 function expert_integrateWithVC() {
 vc_map( array(
"name" => __( "Expert", "my-text-domain" ),
"base" => "expert",
"class" => "",
"category" => __( "Custom", "my-text-domain"),
"params" => array(
array(
"type" => "attach_image",
"holder" => "div",
"class" => "",
"heading" => __( "Choose Expert Image", "my-text-domain" ),
"param_name" => "expert_image",
"value" => __( "", "my-text-domain" )

),
array(
"type" => "textfield",
"holder" => "div",
"class" => "",
"heading" => __( "Expert Name", "my-text-domain" ),
"param_name" => "expert_name",
"value" => __( "", "my-text-domain" )
 ),
array(
"type" => "textfield",
"holder" => "div",
"class" => "",
"heading" => __( "Expert Designation", "my-text-domain" ),
"param_name" => "expert_designation",
"value" => __( "", "my-text-domain" )
),
array(
"type" => "attach_image",
"holder" => "div",
"class" => "",
"heading" => __( "Add Year of Expirience image", "my-text-domain" ),
"param_name" => "expert_exp_image",
"value" => __( "", "my-text-domain" )
 ),
 array(
 "type" => "textfield",
 "holder" => "div",
 "class" => "",
 "heading" => __( "Expert's Expirience Short Description", "my-text-domain" ),
 "param_name" => "expert_short_desc",
 "value" => __( "", "my-text-domain" )
 ),
 array(
"type" => "textarea",
"holder" => "div",
"class" => "",
"heading" => __( "Short Description of Expert", "my-text-domain" ),
"param_name" => "expert_description",
"value" => __( "", "my-text-domain" )
),
 array(
 "type" => "vc_link",
 "holder" => "div",
 "class" => "",
 "heading" => __( "Choose Rediect URL", "my-text-domain" ),
 "param_name" => "url",
 "value" => __( "", "my-text-domain" ),
 "description" => __( "Add Short Description", "my-text-domain" )
 )

 )
 ) );
 }

我想要的只是返回选定的 URL。我是 wordpress 的新手。先感谢您。

Answer 1

您没有提取 URL，因此if( !empty($url) ) {不会触发，您应该将所有变量添加到提取代码中。

function expert_func( $atts ) {

  extract( shortcode_atts( array(
    'expert_image'  => '',
    'expert_name'  => '',
    'expert_designation' => '',
    'expert_exp_image' => '',
    'expert_short_desc' => '',
    'expert_description'  => '',
    'url' => '',
  ), $atts ) );

  $img_url = wp_get_attachment_image_src( $expert_image, "full");

  $url_link = vc_build_link($url);

  your code...

  if (isset($url_link['url'])) {

    $result .= '<a href="'.esc_url($url_link['url']).'" class="learn-btn">'.$url_link['title'].'</a>';

  }

  your code etc...

}

可以查（附截图）
