preg_replace() Xtemplate question

[jenny]

Hello,

 

I'm getting an error with XTemplate class from:

http://sourceforge.net/project/showfiles.php?group_id=16714&package_id=14016&release_id=319432

 

 

the error message is:

 

preg_replace() [<a href='function.preg-replace'>function.preg-replace</a>]: Unknown

modifier '|'

 

the function that causes the error:

 

function parse ($bname) {

 

if (isset($this->preparsed_blocks[$bname])) {

 

$copy = $this->preparsed_blocks[$bname];

 

} elseif (isset($this->blocks[$bname])) {

 

$copy = $this->blocks[$bname];

 

} elseif ($this->_ignore_missing_blocks) {

// ------------------------------------------------------

// NW : 17 Oct 2002. Added default of ignore_missing_blocks

//      to allow for generalised processing where some

//      blocks may be removed from the HTML without the

//      processing code needing to be altered.

// ------------------------------------------------------

// JRC: 3/1/2003 added set error to ignore missing functionality

$this->_set_error("parse: blockname [$bname] does not exist");

return;

 

} else {

 

$this->_set_error("parse: blockname [$bname] does not exist");

}

 

/* from there we should have no more {FILE } directives */

if (!isset($copy)) {

die('Block: ' . $bname);

}

 

$copy = preg_replace($this->filevar_delim_nl, '', $copy);

 

$var_array = array();

 

/* find & replace variables+blocks */

preg_match_all("/" . $this->tag_start_delim . "([A-Za-z0-9\._]+? ?#?.*?)" . $this->tag_end_delim. "/", $copy, $var_array);

$var_array = $var_array[1];

 

foreach ($var_array as $k => $v) {

 

// Are there any comments in the tags {tag#a comment for documenting the template}

$any_comments = explode('#', $v);

$v = rtrim($any_comments[0]);

 

if (sizeof($any_comments) > 1) {

 

$comments = $any_comments[1];

} else {

 

$comments = '';

}

 

$sub = explode('.', $v);

 

if ($sub[0] == '_BLOCK_') {

 

unset($sub[0]);

 

$bname2 = implode('.', $sub);

 

// trinary operator eliminates assign error in E_ALL reporting

$var = isset($this->parsed_blocks[$bname2]) ? $this->parsed_blocks[$bname2] : null;

$copy = preg_replace("/" . $this->tag_start_delim . $v . $this->tag_end_delim . "/m", '', $copy);

 

} else {

 

$copy = preg_replace("/" . $this->tag_start_delim . $v . $this->tag_end_delim . "/", "$nul", $copy);

}

} else {

 

$var = trim($var);

// SF Bug no. 810773 - thanks anonymous

$var = str_replace('\\', '\\\\', $var);

foreach ($sub as $v1) {

 

// NW 4 Oct 2002 - Added isset and is_array check to avoid NOTICE messages

//                if (empty($var[$v1])) { // this line would think that zeros(0) were empty - which is not true

if (!isset($var[$v1]) || (!is_array($var[$v1]) && strlen($var[$v1]) == 0)) {

if (defined($v1)) {

if ($var == '') {

}

$var = str_replace('\\', '\\\\', $var);

// Ensure dollars in strings are not evaluated reported by SadGeezer 31/3/04

$var = str_replace('$', '\\$', $var);

// Replace str_replaces with preg_quote

//$var = preg_quote($var);

$var = str_replace('\\|', '|', $var);

$copy=preg_replace("|" . $this->tag_start_delim . $v . " ?#?" . $comments . $this->tag_end_delim . "|", "$var", $copy);

}

}

 

if (isset($this->parsed_blocks[$bname])) {

$this->parsed_blocks[$bname] .= $copy;

} else {

$this->parsed_blocks[$bname] = $copy;

}

 

/* reset sub-blocks */

if ($this->_autoreset && (!empty($this->sub_blocks[$bname]))) {

 

reset($this->sub_blocks[$bname]);

 

foreach ($this->sub_blocks[$bname] as $k => $v) {

$this->reset($v);

}

}

}

 

 

the error references this line:

 

  $copy=preg_replace("|\s*" . $this->tag_start_delim . $v . " ?#?" . $comments . $this->tag_end_delim . "\s*\n|m", '', $copy);

 

thanks in advance for you help!!

Your delimiter is a | and you're using a | somewhere in your pattern. I recommend quoting the pattern and changing the delimiter.
