    <p>I'm receiving the error above in the get_template() function of my class listed below. Does anyone know why I am receiveing this error? All of the other queries execute fine and $template_number is definitely returning an int which is expected at this point in the query so why am I receiving this error? Could it be because the return on this query is formatted as TEXT in MySQL (and appears as a BLOB in PHPMyAdmin?</p> <pre><code> class Page{ private $con; public function __construct(Connection $con) { $this-&gt;con = $con; if(isset($_GET['id'])){ $id = $_GET['id']; }else{ $id = 1; } $this-&gt;get_headers($id); $this-&gt;get_content($id); $this-&gt;get_footer($id); } private function get_headers($pageId){ $retrieveHead = $this-&gt;con-&gt;prepare("SELECT headers FROM pages WHERE page_id=?"); $retrieveHead-&gt;bind_param('i',$pageId); $retrieveHead-&gt;execute(); $retrieveHead-&gt;bind_result($header); $retrieveHead-&gt;fetch(); $retrieveHead-&gt;close(); echo $header; } private function get_footer($pageId){ $retrieveFooter = $this-&gt;con-&gt;prepare("SELECT footer FROM pages WHERE page_id=?"); $retrieveFooter-&gt;bind_param('i',$pageId); $retrieveFooter-&gt;execute(); $retrieveFooter-&gt;bind_result($footer); $retrieveFooter-&gt;fetch(); $retrieveFooter-&gt;close(); echo $footer; } private function get_content($pageId){ $retreiveContent = $this-&gt;con-&gt;prepare("SELECT template_id, section_title, i1, i2 FROM content WHERE page_id=?

    1. COmost of the time you can assume `Call to a member function bind_param() on a non-object` is because you are calling `->bind_param` on `false` because the prepare failed. I'm assuming it is because of `$this->con`. You should implement mysqli, not pass the class in.

    2. COIt works for all the other queries in the other functions so this is not the issue.

    3. COThe error includes a line number, which unfortunately you have not provided. Go to that line and `var_dump` whatever it is that you are calling `bind_param` on. The rest will debug itself.

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.

SQuiL has stopped working due to an internal error.

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