PHP Fatal error: Call to a member function find() on a non-object however my function work

php, simple-html-dom

Solution

Based on the information you’re providing the best and most practical solution is to simply do a check to see if `$html` and `$content` is empty or not.

9 times out of 10 when you get a “Call to a member function [whatever the function is] on a non-object” that basically means the object just doesn’t exist. Meaning the variable is empty. Here is your code reworked:

$url = "static/" . $cat_map[$cat]['url'];
if (!empty($url)) {
  $html = file_get_html($url);
  if (!empty($html)) {
    $content = $html->find('div#event-pane > div#e' . $event_id, 0);
    if (!empty($content)) {
      $content->find('a.openevent', 0)->innertext = '';
      $content->find('h3.lshtitle', 0)->onclick = '';
      $content->find('h3.lshtitle', 0)->tag = 'div';
      $content->find('div.lshtitle', 0)->class = 'ttl';
    }
  }
}

Also, I added a check to see if the `$url` is empty as well.

Problem

I am getting this error on Line 71 of my code, however the function of this line is executed correctly and it does what I expect it to do. However, I noticed that my error log is full of these lines: [09-Dec-2013 14:54:02 UTC] PHP Fatal error: Call to a member function find() on a non-object in /home/sportve/public_html/open_event_common.php on line 71 What I have checked for: `simple_html_dom_parser` is already included and this function that Line 71 intend to do is working. Here is Line 71 of my code: ``` $content->find('a.openevent', 0)->innertext = ''; ``` so its confusing as to what is causing this error to appear in my error log file? Edit: here is the full code: ``` <?php $url = "static/" . $cat_map[$cat]['url']; $html = file_get_html($url); $content = $html->find('div#event-pane > div#e' . $event_id, 0); $content->find('a.openevent', 0)->innertext = ''; $content->find('h3.lshtitle', 0)->onclick = ''; $content->find('h3.lshtitle', 0)->tag = 'div'; $content->find('div.lshtitle', 0)->class = 'ttl'; ?> ```
