    <p>I have an article formatted in HTML. It contains a whole lot of jargon words that perhaps some people wouldn't understand.</p> <p>I also have a glossary of terms (MySQL Table) with definitions which would be helpful to there people.</p> <p>I want to go through the HTML of my article and find instances of these glossary terms and replace them with some nice JavaScript which will show a 'tooltip' with a definition for the term.</p> <p>I've done this nearly, but i'm still having some problems:</p> <ul> <li>terms are being found within words (ie: APS is in Perhaps)</li> <li>I have to make sure that it doesn't do this to alt, title, linked text, etc. So only text that doesn't have any formatting applied. BUT it needs to work in tables and paragraphs.</li> </ul> <p>Here is the code I have:</p> <pre><code>$query_glossary = "SELECT word FROM glossary_terms WHERE status = 1 ORDER BY LENGTH(word) DESC"; $result_glossary = mysql_query_run($query_glossary); //reset mysql via seek so we don't have to do the query again mysql_data_seek($result_glossary,0); while($glossary = mysql_fetch_array($result_glossary)) { //once done we can replace the words with a nice tip $glossary_word = $glossary['word']; $glossary_word = preg_quote($glossary_word,'/'); $article['content'] = preg_replace_callback('/[\s]('.$glossary_word.')[\s](.*?&gt;)/i','article_checkOpenTag',$article['content'],10); } </code></pre> <p>And here is the PHP function:</p> <pre><code>function article_checkOpenTag($matches) { if (strpos($matches[0], '&lt;') === false) { return $matches[0]; } else { $query_term = "SELECT word,glossary_term_id,info FROM glossary_terms WHERE word = '".escape($matches[1])."'"; $result_term = mysql_query_run($query_term); $term = mysql_fetch_array($result_term); # CREATING A RELEVENT LINK $glossary_id = $term['glossary_term_id']; $glossary_link = SITEURL.'/glossary/term/'.string_to_url($term['word']).'-'.$term['glossary_term_id']; # SOME DESCRIPTION STUFF FOR THE TOOLTIP if(strlen($term['info'])&gt;400) { $glossary_info = substr(strip_tags($term['info']),0,350).' ...&lt;br /&gt; &lt;a href="'.$glossary_link.'"&gt;Read More&lt;/a&gt;'; } else { $glossary_info = $term['info']; } return ' &lt;a href="javascript:;" onmouseout="UnTip();" class="article_jargon_highligher" onmouseover="'.tooltip_javascript('&lt;a href="'.$glossary_link.'"&gt;'.$term['word'].'&lt;/a&gt;',$glossary_info,400,1,0,1).'"&gt;'.$matches[1].'&lt;/a&gt; '.$matches[2]; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
