str_replace not working

[ziycon]

I have this code below and its not working, the $title out puts the title fine but its not wrapping the $q (query word) with a <strong></strong>!???

$sql = mysql_query("SELECT id,title,body,date,time FROM ".$table." WHERE title LIKE '%".$q."%' ORDER BY date DESC, time DESC");
  while($row = mysql_fetch_array($sql))
  {
	$link_name = preg_replace('#[^a-zA-Z0-9]+#','-',$row['title']);
	$title = str_replace($q,'<strong>'.$q.'</strong>',$row['title']);
    echo '<div class="search_results_wrapper">
		<div class="search_results_link_name"><div class="search_results"><a href="'.$link.$row['id'].'-'.$link_name.'.htm">'.$title.'</a></div></div>
		<div class="search_datetime">'.strftime("%b %d, %Y", strtotime($row['date'])).' at '.wordwrap(substr($row['time'],0,5)).'</div>
		<div class="search_results_body">'.add_dots(format_article_2($row['body']),'|',150).'</div>
		<div class="search_results_url">www.ign.ie/'.$link.$row['id'].'-'.$link_name.'.htm</div>
    </div>
';
  }

where should this wrapping happen? I can't spot the place in your code.

Line 5:

$title = str_replace($q,'<strong>'.$q.'</strong>',$row['title']);

You don't define anywhere $q.

[ziycon]

Its being passed in as a parameter in the function that the code snippet above is from.

Just for interest sake to see what the problem is, can you try:

$x = "<strong>" . $q . "</strong>";
echo($x);
$title = str_replace($q , $x , $row['title']);

[ziycon]

That bit of code outputs the query string in <strong> tags but the title isn't changed!?!

[TheServant]

OK, what is an example value of $q and $row['title']?
Also, how do you output the $title? Is it just echo($title)?

[ziycon]

Yes $title is just being echoed.

Examples below:

$q = 'dog';
$row['title'] = 'The dog went to the park today';

[TheServant]

I have just tried:

	$q = "dog";
	$row['title'] = "the dog went to the park";
	$x = "<strong>" . $q . "</strong>";
	$title = str_replace($q , $x , $row['title']);
	echo($title);

And it worked fine. Also tried:

	$row = array("cat went home","dog was dead","mouse likes cheese");
	$q = "dog";
	$x = "<strong>" . $q . "</strong>";
	$title = str_replace($q , $x , $row[1]);
	echo($title);

Which also worked. If these are not working on yours then your PHP is not working properly. What version are you using?

[ziycon]

I don't understand, it's not working for my, PHP is working fine, been using it for over 3 years now!!

[TheServant]

OK, what about replacing <strong></strong> with <span style="font-weight: bold;"></span>. That will tell if it's the str_replace or <strong>. Are you sure you're not re-defining the font weight or properties somewhere else with another class or style? What is your search_results_ link_name class define?

[ziycon]

Turns out that it was working to some extent, if the search was test the it would only highlight test that was exactly the same like test but wouldn't highlight Test, it was case sensitive. Thanks for the help.

No worries, glad you got it sorted out.
