在返回函数中添加php快捷代码

时间：2012-08-27 作者：agis

我有这部分代码：

return \'<img class="myimage \'.$text_color.\' \'.$horizontal.$slide_fitscreen.\'" src="\'.$image.\'" alt="" \'.$slide_desc.\' />\';
我想做的是返回一个php短代码，但不在img 元素，因为我的短代码生成a 元素，所以我需要在img之后返回它

这是我的短代码：

<?php echo do_shortcode(\'[daisy]\'); ?>
我试过这个：

return \'<img class="myimage \'.$text_color.\' \'.$horizontal.$slide_fitscreen.\'" src="\'.$image.\'" alt="" \'.$slide_desc.\' />\'.do_shortcode(\'[daisy]\');
但不起作用，我收到：

Error (Parseerror): Syntax Error Unexpected Token <
我该怎么做？谢谢稍后编辑：以下是整个脚本：

请勿致电do_shortcode(). 请改用关联的处理程序。

如果要调用不带参数的短代码，则必须在处理程序声明中使参数为可选的：

function custom_slidessc($atts = array(), $content = null)
因此，您需要的是：

return \'<img>\' . custom_slidessc();

SO网友:Edward Caissie

do_shortcode 需要回显以将其输出打印到屏幕上，因此您需要找到一种解决方法。这里有一个想法：

// Start an output buffer to capture the echo
ob_start();

echo do_shortcode( \'[daisy]\' );

//Put the output into a usable variable */
$daisy_output = ob_get_contents();

//End the output buffer capture
ob_end_clean();

return \'<img class="myimage \' . $text_color . \' \' . $horizontal . $slide_fitscreen . \'" src="\' . $image . \'" alt="" \' . $slide_desc . \' />\' . $daisy_output;
可能有更好的方法，但至少这应该为您试图获得的输出提供概念证明。

我有一个对性能至关重要的站点。在使用短代码时，我考虑了服务器解析和返回内容所需的时间，而不是允许一些HTML(<div class=\"redletter\">) 浏览TinyMCE编辑器。与此同时，我的代码是：// [redletter]Content[/redletter] add_shortcode(\'redletter\', \'redletter_do\'); function redletter_do($atts, $content = null) {
