I've made as script using file_get_html. I'm now transfering it to a Wordpress site, and it doesn't seem to work.

Just trying to use it in a admin plugin.

Snippet below:

require('includes/simple_html_dom.php');

if (isset($_POST['submit_updateColors'])) {

        $qGetBrands = $mysqli->query("SELECT ... ");

        while ($rowBrands = $qGetBrands->fetch_assoc()) {



            $brandId = $rowBrands['cl_brand_Id'];

            $url =  "https://www.url.com". $rowBrands['cl_brand_url'];

            $html = file_get_html($url);

            $html->find('div[class=col-md-1p5]');



            foreach($html->find('div[class=col-md-1p5]') as $brandColors) {

                foreach ($brandColors->find('h3') as $brandColor) {

                    $p_brandColor = $brandColor->innertext;

                }



                foreach ($brandColors->find('img') as $ColorImg) {

                    $p_ColorImg = $ColorImg->src;

                }                   

                    echo $p_brandColor ." <br />";

                    echo $imgName['basename'] ." <br /> <br />";

            }

        }

    }

After while have started:
echo "I'm here!!!"
Results: "I'm here!!!"

After first foreach:
echo "I'm here!!!"
Results: Nothing

After $html = file_get_html($url);:
echo "Result: ".$html;
Results: Nothing, not even showing "Result"

Error messages:

I have no idea how to proceed, and would love to get some help!
Outside wordpress, it works perfectly.

I hope I havent removed too much informaton.

Thanks in advance!

Moving my earlier comment and some more hints here.

A good start would be to enable error reporting with

error_reporting(E_ALL);

ini_set('display_errors', 1);

Start from there.. I suspect that some includes are missing and you have to use the global $db object to access the DB in WP.

Looking at your errors - apparently, $html variable is boolean and not a htmlDOM object. According to this, file_get_html() returns false, if fetched content is empty or exceeds MAX_FILE_SIZE.

Check if the URL you are retrieving really exists, you have rights to access it, and MAX_FILE_SIZE is set correctly

I was able to solve this by looking at file_get_contents(): stream does not support seeking ／ When was PHP behavior about this changed?

On line 75 of simple_html_dom.php:

$contents = file_get_contents($url, $use_include_path, $context, $offset);
I removed the reference to $offset:

$contents = file_get_contents($url, $use_include_path, $context);
No my page works fine. Not taking liability for anything else it breaks! :)
