Question

I use simplehtmldom for parsing a website to get all images.

Everytime i add a link the error occurs:

Fatal error: Call to a member function find() on a non-object

Code:

<form method="post">
Link <input type="text" name="link" size="50"/>
<input type="submit" />
</form>


<?php


if($link != "")
{
    include_once('simple_html_dom.php');
        $html = $_POST[link]

    // Find all images 
    foreach($html->find('img') as $element)
    {
        echo $element->src . '<br>';
    }
}
?>

<form method="post">
Link <input type="text" name="link" size="50"/>
<input type="submit" />
</form>


<?php


if($link != "")
{
    include_once('simple_html_dom.php');
        $html = file_get_html($_POST['link']);

    // Find all images 
    foreach($html->find('img') as $element)
    {
        echo $element->src . '<br>';
    }
}
?>

You must use constructor for its member functions $html = file_get_html($_POST['link']);

$html = $_POST['link'] String

$html = file_get_html($_POST['link']); Class
