Substr get_post_meta数据？

问题描述：

How can I limit the text to say 100 characters from the get_post_meta tag?

I need to grab the text in this style:

<?php echo get_post_meta($relationship->ID, 'company_description', true ); ?>

This is how I would normally limit the text but I don't know how to combine it with the syntax above:

<?php echo substr($fields->company_description,0,100) . "..."; ?>

如何将文本限制为从get_post_meta标记中说出100个字符？ p>

 ＆lt;？php echo get_post_meta（$ relationship-＆gt; ID，'company_description'，true）;  ？＆GT;  
  code>  pre> 
 
 这就是我通常限制文本的方法，但我不知道如何将其与上述语法结合起来： p> 
 
  ＆lt;？php echo substr（$ fields-＆gt; company_description，0,100）。  “......”;  ？＆gt; 
  code>  pre> 
  div>

答

The most readable way:

$text = get_post_meta($relationship->ID, 'company_description', true);
echo substr($text, 0, 100) . "...";

Then of course, you could also nest the function calls, which probably sucks in terms of readability:

echo substr(get_post_meta($relationship->ID, 'company_description', true), 0, 100) . "...";

By the way: If company_description might contain raw HTML, you'll probably want to run strip_tags() over it before getting a substring – not stripping HTML would get you in trouble in the long run otherwise.

$text = strip_tags(get_post_meta($relationship->ID, 'company_description', true));
echo substr($text, 0, 100) . "...";
