(SOLVED)readmore break on my site

Quote popularanky:

I have a website that is use to post information like blog. All I want is a code that will help me break from the second line of word and put the readmore link to a new page that shows the full details of the post. Like on blogs

  
$pattern = '/\n/';  
preg_match($pattern, $articles->article_text->GetValue(), $matches);  
$articles->article_text->SetValue($matches[0]);  
  
  
The above should shorten the label control to display the text up until the first line break.  The {article_id} link control should have static text "Read More..." and link to articles_detail.php passing the parameter article_id.  The detail page can then have a "record" which has a label showing the full article text.

Hmmm...this is off the top of my head, untested. How are you getting the articles? I assume you are storing them in a database. Let's say you have a table called "articles" consisting of article_id and article_text. The article_id is the primary key and article_text field is a blob or whatever. Now let's assume you have a page articles_summary.php and articles_detail.php. Place a grid on the summary page called articles, select * from articles table. Then on the grid populate two controls, one label control for {article_text} and one link control for {article_id}. Finally in the before show event for the {article_text}:

 $pattern = '/\n/'; preg_match($pattern, $articles->article_text->GetValue(), $matches); $articles->article_text->SetValue($matches[0]);

$pattern = '/\n/'; preg_match($pattern, $problem->pro_desc->GetValue(), $matches); $problem->pro_desc->SetValue($matches[0]);

and line 22 is

$problem->pro_desc->SetValue($matches[0]);

  
$pattern = '/\n/';  
$string = $problem->pro_desc->GetValue();  
if (preg_match($pattern, $string, $matches, PREG_OFFSET_CAPTURE)) {  
  //we found a line break, get the offset  
  $offset = $matches[0][1];  
  $chopstring = substr($string,0,$offset);  
} else {  
  //no line break, so just grab the first 100 characters;  
  $chopstring = substr($string,0,100);  
}  
$problem->pro_desc->SetValue($chopstring);

Hi clahti2 thanks for the code,
I was looking for some thing like this recently.
is there a simple piece of code which would allow me to chop at 100 characters for (sample) article-id and article-text ?

thanks again
