简码不起作用。返回错误信息

Question

我有用于编写自定义短代码的代码。但是它返回此错误消息。如何克服这个错误。

[注意：我也尝试过在启动html之前关闭php标签，并在结束html之后再次启动它]

错误是因为您尝试在php块中输出html。您必须使用php end / start标记

// Add Shortcode
    function custom_shortcode() {
ob_start();
?>

<div class=intro> ... </div> //... exactly the code you got now 

<?php

return ob_get_clean();  //ob_get_clean() is returning everything you echoed or rendered since ob_start()
}
add_shortcode( 'kollol', 'custom_shortcode' );
