First Paragraph Limiter

[Fran]

Is there any way to limit the text just to the first paragraph of the body lets say? Thanks very much guys.

In a hurry, so, quick answer. Assuming that you want to limit this to echo a summary on the site (as opposed to limit the editing to only one paragraph), a quick google search returned this http://www.webdevdoor.com/php/php-get-first-paragraph-function

Thanks Diogo

I tried this:

<?php
      $lotes = $pages->get(1025)->children();
      function getFirstPara($string) {
      $string = substr($string,0, strpos($string, "</p>")+4);
      return $string;
      }
      foreach ($lotes as $lote) {
      echo getFirstPara($lote->body);
      }
?>

And it worked great !!!

Great!

You might want to move that function to a file that is called by all the others, so you have it available averywhere, like _func.php or even the head file if you prefer.

In the latest 3.x version, there's also some nice additions that will let you easily do this.

Nice. Funny that there is a regex example that seems to do what ts wants.

<?php

// render the first found paragraph only

if(preg_match('!(<p>.+?</p>)!', $value, $matches)) {

echo $matches[1];

}

Regex is basically voodoo to me so i don't quite understand the exclamation marks but i'm sure Ryan has a better grasp

[BitPoet]

The exclamation marks are simply pattern delimiters. Normally, this is "/", but PHP looks for the first character in a pattern string and treats it as the delimiter. This comes in handy whenever you have a pattern containing a forward slash, as you'd otherwise have to escape it to tell PHP that it's part of the pattern and not its end.

As a follow up question to the first paragraphy solutions provided. Is there a way to get "the rest of the text" output? A way to exclude the first paragraph?

The result I am looking for is to output the first paragraph from a body text field, then an image from an image field, and then the rest of the text from the body text field. So there might be other solutions?
