我有一个贷款计算器插件，它有以下代码块。 它将变量设置为$calcHTML，然后将其返回以将其发布到屏幕。 它看起来像很多代码，但它实际上只是将一堆 html 放入变量然后返回它。
我想将另一个插件中的社交按钮放在$calcHTML中间，以便我的社交按钮输出到计算器上。
输出我的社交按钮的代码是：
社交插件代码
if ( function_exists( 'rtsocial' ) ) { echo rtsocial(); }
如何使用上述函数并将其组合在一起，以便将输出放置在下面的$calcHTML变量中？
下面的计算器代码
add_shortcode('clc_car_loan_calculator', 'clc_car_loan_calculator');
function clc_car_loan_calculator($atts) {
$queryString = '';
if(isset($atts['currency'])) {empty($queryString)?$queryString .= '?':$queryString .= '&'; $queryString .= 'currency='.urlencode($atts['currency']);}
if(isset($atts['theme'])) {empty($queryString)?$queryString .= '?':$queryString .= '&'; $queryString .= 'theme='.urlencode($atts['theme']);}
$calcHTML = '<div class="clc-widget clc-fp-widget">

return $calcHTML;
}
if ( function_exists( 'rtsocial' ) ) { $calcvalue = rtsocial(); }
在您的函数中
function clc_car_loan_calculator($atts) {
global $calcvalue;
..
....
......
return $calcHTML.''.$calcvalue;
}
您需要阅读有关字符串运算符的信息
如果你想把一些内容放在中间，你需要这样做，
如下if ( function_exists( 'rtsocial' ) ) {
$calcHTML .= rtsocial();
}
.运算器用于串联。您的整个函数现在将如下所示
<?php
function clc_car_loan_calculator($atts) {
$queryString = '';
if(isset($atts['currency'])) {empty($queryString)?$queryString .= '?':$queryString .= '&'; $queryString .= 'currency='.urlencode($atts['currency']);}
if(isset($atts['theme'])) {empty($queryString)?$queryString .= '?':$queryString .= '&'; $queryString .= 'theme='.urlencode($atts['theme']);}
