Text brake on parts

BITRU

i use the fallowing code to brake my text on parts and show on different pages. First page work fine but after first page all gets mesed up.

<?php
//GOING THRUE START SIQUANCE
error_reporting(0);
Include ( "Pas.php" );
   mysql_connect($dbHost, $dbUser, $dbPas) or
       die("Could not connect: " . mysql_error());
   mysql_select_db($dbName);

$nid='25';

$querynew = "SELECT nid, ntitle, ntext from news where nid=$nid limit 1";
$resultnews = mysql_query($querynew);
list ($nid, $ttitle, $ttext) = mysql_fetch_row($resultnews);

function cut($text, $len = 800, $cutfrom = 677) { 
global $last_blank;
//cut string after one more character than allowed 
  $len++; 
  $cuttext = substr($text, $cutfrom, $len); 
  if (strlen($cuttext) == $len and $cuttext{$len - 1} != ' .') { 
  //last character is not a space so we have to cut off one more word 
    //position of last blank 
    $last_blank = strrpos($cuttext, '.'); 
    //remove last word 
    $cuttext = substr($cuttext, $cutfrom, $last_blank); 
  } 
  //trim output 
  return ($cuttext); 
}

?>

<html><head><title>TEST</title></head>
<div align='center'><? echo "$ttitle"; ?><br></div>
			  <? 

		  if ($cutfrom == ' ' )
		  		{
					$ttext = cut($ttext, '800');
					echo "$ttext <br> and: $last_blank"; 
		    	}
		  else
		  		{
		  			$ttext = cut($ttext, '800', $cutfrom); 
		  			echo "$ttext <br> and: $last_blank"; 
		  		}

$mainnews="<a href='index.php?nid=$nid&mag=$mag'><IMG SRC ='images/mainnews.jpg' BORDER=0></a>";

$pageb=$page;
$pagen=$page;

if 
	( $pageb == '' or $pageb == '0' ){}
else 
	{ $pageb=$pageb-'1';
	$backpage="<a href='test.php?nid=$nid&page=$pageb'><IMG SRC ='images/back.jpg' BORDER=0></a>";}

if ( $pagen == '' )
	{ $pagen=$pagen+'1';
	$nextpage="<a href='test.php?page=$pagen&cutfrom=$last_blank'><IMG SRC ='images/next.jpg' BORDER=0></a>";}
else 
	{ $pagen=$pagen+'1';
	$nextpage="<a href='test.php?page=$pagen&cutfrom=$last_blank'><IMG SRC ='images/next.jpg' BORDER=0></a>";}

?>

<table width='50%'>
<td width='33%'><? echo "$backpage"; ?></td>
<td width='33%'><? echo "$mainnews"; ?></td>
<td width='33%'><? echo "$nextpage"; ?><td></tr>

Sorry... I will try to explain.
I have a text in MySql text field (long article). On my page i wanna to show this text 🙂. But my text is for EXAMPLE 8000 characters long, but on my page i can show only 30 lines (800 cheracters).
SOOO, i want to brake my text on parts. On Page 1 char 0-800, Page 2 char 800-1600..........
I add some stuff (with help of guru member of this forum) because i dont want to brake words in midle.
So my pages might brake text as p1 = 0 - 790, p2 = 790 - 1567.....
But my function it does not work as i want. Firs page is ok 0-790 but 2nd is mesed up it shows something like 845-960 i cant even figure out.

It will be cool to make brakes after 30 lines but i dunno how to do it, so at least i want to make this stuff work

Hope this is more explanatory.

Thanks all in advance.

Hi,

I am not sure whether this:

function cut($text, $len = 800, $cutfrom = 677) {

shouldn't be this:
function cut($text, $len, $cutfrom) {

It's not easy t odebug this just by looking at it, but I have some questions for you:

Look at this line

if (strlen($cuttext) == $len and $cuttext{$len - 1} != ' .') {

I'm not terribly clear on what you are trying to achieve here, but I would imagine that those curly brackets (or braces) around "$len - 1" should probably be square brackets.

Also, you appear to be checking if a character is not equal to a string, which will always be true if that string contains more than one character. Your string ' .' contains two characters - "space dot".

Also:

$last_blank = strrpos($cuttext, '.');

doesn't locate the last blank, it locates the last full stop (or decimal point, or period, or "dot" in a web or email address).

//remove last word
$cuttext = substr($cuttext, $cutfrom, $last_blank);

Shouldn't this now be cutting only from the end? You're chopping off stuff at the start here as well. I would suggest that $cutfrom here should be replaced with 0.

Finally, I think your design is over complicated. You should just be able to achieve this by passing a news id and page number to your script. It should then be able to calculate the start and end points of the cut itself.

Best of luck!

I'm not sure BITRU wrote it; the comments are too well-written.

I do note this:

$cuttext{$len - 1} != ' .'

will always evaluate to true, because a one-character string could never be a two-character string.

$ttext = cut($ttext, '800', $cutfrom);

Since $cutfrom is presumably supposed to contain the value from the GET request (if there is one), then it may be a case of Newbies Forum FAQ Question One. It should also be given a default value in the event that it doesn't get one from the request (it should also be checked to make sure it's numeric).

'SELECT nid, ntitle, ntext from news where nid=$nid limit 1'

There's not a huge point in selecting a field for which you already know the value.

$nid='25';

I really don't know why some people feel it's necessary to quote their numbers like this.

But I'm nitpicking now.
