I'm looking how I can get <p id="test"></p> as number in PHP. I have select option and with code below I get my variation id selected as html paragraph <p id="test"></p> but I need it as number in PHP to run another PHP code to compere something how can I convert <p id="test"></p> to a number in php without using another java script I just need number form my code below as variable number in php.

I'm using woocommerce plugin in WordPress and I need new way of showing images based on user selected option in single product page instead of switching I need to overlay product image with variation images because of that I have user selected option with code below but I need it to work in php I don't know how to convert <p id="test"></p> this code to php to get number and do my other things I know how to do I just need to get <p id="test"></p> as number in php .

 <?php

 if ( $product->is_type('variable') ) {

      ?>
      <script>
      jQuery(document).ready(function($) {

         $('input.variation_id').change( function(){
            if( '' != $('input.variation_id').val() ) {

               var var_id = $('input.variation_id').val();
               document.getElementById('test').textContent = var_id;
            }
         });

      });
      </script>
      <?php

   }

  ?>

I need to get instead of this <p id="test"></p> a number in php .

  • So you have several p elements which each contain an image, and you want to identify the selected one ? – PHPnoob Jan 19 '20 at 15:10

First, make sure the server let you fetch the data.

Second, use a html parser instead to parse the data.

// Gets the webpage
$html = @file_get_contents('https://yourwebsite.com/yourpage');

//if no webpage found die and return an error
if (!$html) {
  die('can not get the content!');
}

//Create a new DOM Doc
$doc = new DOMDocument();

//Load the HTML of the page you fetch in the DOM Doc
$doc->loadHTML($html);

//Get the element with the ID test
$content = $doc->getElementById('test');

Note that if the element is empty, the Dom returns NULL

Don't use javascript for that.

You can learn more about DOMDocument on the PHP doc:

https://www.php.net/manual/en/class.domdocument.php

And here's more about the getElementById
