我认为您可以使用以下代码来执行此操作：

$content = get_the_content();
//write the begining of the shortcode
$shortcode = \'[gallery\';

$check = strpos($content,$shortcode);
if($check=== false) {
  //Code to execute if there isn\'t the shortcode
} else {
  //Code to execute if the shortcode is present
}

您可以创建自己的函数，

// check the current post for the existence of a short code
function has_shortcode( $shortcode = NULL ) {

    $post_to_check = get_post( get_the_ID() );

    // false because we have to search through the post content first
    $found = false;

    // if no short code was provided, return false
    if ( ! $shortcode ) {
        return $found;
    }
    // check the post content for the short code
    if ( stripos( $post_to_check->post_content, \'[\' . $shortcode) !== FALSE ) {
        // we have found the short code
        $found = TRUE;
    }

    // return our final results
    return $found;
}

if(has_shortcode(\'[gallery]\')) {  
    // perform actions here  
} 

在网上某处找到此文件并使用了一次或两次

//first we check for shortcode in the content
$tempContent = get_the_content();
$tempCheck = \'[gallery\';

$tempVerify = strpos($tempContent,$tempCheck);
if($tempVerify === false) {
  //Your Shortcode not found do nothing ? you choose
} else {
    echo do_shortcode(\'[gallery]\');
}

（我知道[画廊缺了]…就这样吧）

This should be used inside the loop..<希望这有帮助，萨吉夫

WordPress允许您检查是否存在短代码。

要检查它，您可以使用shortcode_exists() 作用如果短代码存在，则返回true。

<?php if ( shortcode_exists( $tag ) ) { } ?>

<?php
if ( shortcode_exists( \'latest_post\' ) ) {
    // The short code exists.
}
?>

我知道这是个老问题，但有些人可能仍然需要这个，特别是因为shortcode_exists() 可能不适用于某些插件短代码：

$shortcode_result = do_shortcode(\'[your_shortcode]\');

if ($shortcode_result != [your_shortcode]) && 
    !empty($shortcode_result))] {

    // do what you need

} else {
    // this is not valide shortcode
}

WP现在有一个内置功能：

<?php
 
if ( shortcode_exists( \'gallery\' ) ): ?>

    // The short code exists.

<?php else: ?>

   // It DOESN\'T EXIST

<?php endif;?>
