split_text function (text_frame_decorator.cls.php) requires PHP > 5.2.6 for multibytes strings #35

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Use UTF-8 strings. 
2. When the line break offset is calculted to be after a word containing a
UTF8 special (like "é"), the strip_text function does not separate the html
tag correctly.

What is the expected output? What do you see instead?
The multibyte symbol is not displayed correctly and the rest of the line
(within the same html tag) is removed.

What version of the product are you using? On what operating system?
Works with PHP 5.2.9, doesn't with PHP <= 5.2.6

Please provide any additional information below.
see PHP Bug http://bugs.php.net/bug.php?id=46335

replace the strip_text function by this one :
function split_text($offset) {
  if ( $offset == 0 )
      return;

    //Bug for PHP <= 5.2.6  : http://bugs.php.net/bug.php?id=46335 
    //$split = $this->_frame->get_node()->splitText($offset);
    $node = $this->_frame->get_node();
    $clone = $node->cloneNode(true);

    //set new content of original $node
    $node->deleteData($offset, mb_strlen($node->textContent));

    //Add Node after with remaining text
    $clone->deleteData(0, $offset);
    $parent = $node->parentNode;
    $parent->appendChild($clone);

    $deco = $this->copy($clone);    

    $p = $this->get_parent();
    $p->insert_child_after($deco, $this, false);
    if ( $p instanceof Inline_Frame_Decorator )
      $p->split($deco);
}

Sorry the function name is split_text, not strip_text

This solution didn't solve my problem (i use PHP 5.3.2 on Ubuntu), after i 
replace that function DOMPDF continued breaking words very bad.
I tried with something somebody posted on the following link and it solved it 
all:
http://www.dashinteractive.net/dompdf/index.php?v=3153736

What tommylacroix proposes is:

function split_text($offset) {
    if ( $offset == 0 )
      return;

    $text = $this->_frame->get_node()->nodeValue;

    $split = $this->_frame->get_node()->splitText($offset);
    $this->_frame->get_node()->nodeValue = mb_substr($text,0,$offset);
    $split->nodeValue = mb_substr($text,$offset);
    $deco = $this->copy($split);
    $p = $this->get_parent();
    $p->insert_child_after($deco, $this, false);

    if ( $p instanceof Inline_Frame_Decorator )
      $p->split($deco);
}

PHP 5.3 doesn't have the bug in the splitText() method, so this patch is 
irrelevant.
