    <p>I have a script that parses certain elements from a webpage and stores them in a mysql db. Everything works fine until I try to split an element and store the resulting data into the db. Any ideas what might be wrong? Here's the page I'm parsing: <a href="http://www.ratemyprofessors.com/SelectTeacher.jsp?sid=953" rel="nofollow">http://www.ratemyprofessors.com/SelectTeacher.jsp?sid=953</a></p> <p>Here's my code:</p> <pre><code>&lt;?php include('simple_html_dom.php'); //connect to db (code emitted) prof_List("http://www.ratemyprofessors.com/SelectTeacher.jsp?sid=953"); function prof_name($url) { // collect data echo $url; $data = new simple_html_dom(); $data-&gt;load_file($url); $profName = $data-&gt;find("//*[@id=profName]", 0); $profName = strip_tags($profName); echo "Full Name: " . $profName = trim($profName); list($first, $last) = explode("&amp;nbsp;", $profName); echo "fname: " . $first; echo "lname: " . $last; //call mysql function insert_row($profName, $first, $last); } function insert_row($profName, $first, $last) { $sql1="INSERT INTO PROFESSOR(name, firstname, lastname) VALUES('$profName','$first', '$last')"; $sql1=strip_tags($sql1); echo $sql1; mysql_query($sql1) or die(mysql_error()); echo "Data Inserted!"; } function prof_List($mainURL) { $list = new simple_html_dom(); $list-&gt;load_file($mainURL); $profLinks = $list-&gt;find("//*[@class=profName]/a"); foreach($profLinks as $profLink) { $profU=$profLink-&gt;href; echo $profURL = "http://www.ratemyprofessors.com/" . $profU; prof_name($profURL); } } ?&gt; </code></pre> <p>Here's my output: </p> <pre><code>Connected to MySQL Connected to Databasehttp://www.ratemyprofessors.com/SelectTeacher.jsp?the_dept=All&amp;sid=953&amp;orderby=TLName&amp;toggel=truehttp://www.ratemyprofessors.com/SelectTeacher.jsp?the_dept=All&amp;sid=953&amp;orderby=TLName&amp;toggel=trueFull Name: fname: lname: INSERT INTO PROFESSOR1(name, firstname, lastname) VALUES('','', '')Data Inserted!http://www.ratemyprofessors.com/ShowRatings.jsp?tid=861228http://www.ratemyprofessors.com/ShowRatings.jsp?tid=861228 Fatal error: Call to a member function find() on a non-object in /Users/user1/Sites/simple_html_dom.php on line 879 </code></pre>

    1. COTry this: $data->file_get_html($url); instead of $data->load_file($url);

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
