Coding help (preg_match, preg_replace)

[masterross]

Hi guys,

I'm trying to update some vB 3.8 hack to vB 4.0
But I stacked on preg_match, preg_replace.
Can you give a hand?

Here is the vb 3.8 code:

PHP Code:

$score     = fetch_reppower($vbulletin->userinfo, $permissions);
$neg_score = intval($score / 2);

$posrepdd = '';
for($i = $score; $i >= 0; --$i) {
  $repdd .= "<option value=\"$i\">$i</option>";
}

$negrepdd = '';
for ($i = $neg_score; $i >= 0; --$i) {
  $negrepdd .= "<option value=\"$i\">$i</option>";
}

$match = "<tr>\s*<td>\s*\\\x24vbphrase\[your_comments_on_this_post\]:";

$m = preg_match("/$match/i", $vbulletin->templatecache['reputationbit'], $matches, PREG_OFFSET_CAPTURE);

if ($m) {
  if ($score == 0) {
    $custom_rep = "<tr><td><input type=\"hidden\" name=\"rep2give\" value=\"0\" /></td></tr>\n";
  } else {
    $custom_rep = "<tr><td><div><label for=\"rb_reputation_give_$postid\"><span id=\"give_rep\">Give <select name=\"rep2give\" id=\"give_$postid\">$repdd</select></span><span id=\"take_rep\" style=\"display: none\">Take <select name=\"rep2take\" id=\"take_$postid\">$negrepdd</select></span> points</label></div></td></tr>\n";
  }
  
  $custom_rep = addslashes($custom_rep);
  $insert     = $matches[0][1];
  $beginning  = substr($vbulletin->templatecache['reputationbit'], 0, $insert);
  $ending     = substr($vbulletin->templatecache['reputationbit'], $insert);

  $vbulletin->templatecache['reputationbit'] = $beginning . $custom_rep . $ending;
  
  if ($score > 0) {
    $find_pos = 'value=..pos';
    $vbulletin->templatecache['reputationbit'] = preg_replace("/$find_pos/", "onclick=\\\"document.getElementById('give_rep').style.display = ''; document.getElementById('take_rep').style.display = 'none'; this.blur();\\\" value=\\\"pos", $vbulletin->templatecache['reputationbit']);
    
    $find_neg = 'value=..neg';
    $vbulletin->templatecache['reputationbit'] = preg_replace("/$find_neg/", "onclick=\\\"document.getElementById('give_rep').style.display = 'none'; document.getElementById('take_rep').style.display = ''; this.blur();\\\" value=\\\"neg", $vbulletin->templatecache['reputationbit']);
  }
} 

And here is the modified mine:

PHP Code:

$score     = fetch_reppower($vbulletin->userinfo, $permissions);
$neg_score = intval($score / 2);

$posrepdd = '';
for($i = $score; $i >= 0; --$i) {
  $repdd .= "<option value=\"$i\">$i</option>";
}

$negrepdd = '';
for ($i = $neg_score; $i >= 0; --$i) {
  $negrepdd .= "<option value=\"$i\">$i</option>";
}

$match = "<div class=\"blockrow\">\s*<label for=\"reason\">\{vb:rawphrase your_comments_on_this_post\}:";

$m = preg_match("/$match/i", $vbulletin->templatecache['reputationbit'], $matches, PREG_OFFSET_CAPTURE);

if ($m) {
  if ($score == 0) {
    $custom_rep = "<input type=\"hidden\" name=\"rep2give\" value=\"0\" />\n";
  } else {
    $custom_rep = "<li><label for=\"rb_reputation_give_$postid\"><span id=\"give_rep\">Give <select name=\"rep2give\" id=\"give_$postid\">$repdd</select></span><span id=\"take_rep\" style=\"display: none\">Take <select name=\"rep2take\" id=\"take_$postid\">$negrepdd</select></span> points</label></li>\n";
  }
  
  $custom_rep = addslashes($custom_rep);
  $insert     = $matches[0][1];
  $beginning  = substr($vbulletin->templatecache['reputationbit'], 0, $insert);
  $ending     = substr($vbulletin->templatecache['reputationbit'], $insert);

  $vbulletin->templatecache['reputationbit'] = $beginning . $custom_rep . $ending;
  
  if ($score > 0) {
    $find_pos = 'value=..pos';
    $vbulletin->templatecache['reputationbit'] = preg_replace("/$find_pos/", "onclick=\\\"document.getElementById('give_rep').style.display = ''; document.getElementById('take_rep').style.display = 'none'; this.blur();\\\" value=\\\"pos", $vbulletin->templatecache['reputationbit']);
    
    $find_neg = 'value=..neg';
    $vbulletin->templatecache['reputationbit'] = preg_replace("/$find_neg/", "onclick=\\\"document.getElementById('give_rep').style.display = 'none'; document.getElementById('take_rep').style.display = ''; this.blur();\\\" value=\\\"neg", $vbulletin->templatecache['reputationbit']);
  }
} 

Thanks in advance!

What is your actual problem ?

[masterross]

hi,

it seems the preg_match doesnt find matches.
If I remove if ($m), $custom_rep is appear in template.

[masterross]

Hmmm...
I think template cannot be called! That's why preg_match doesnt find anything!

Plz give me some hint!
