Message:

Is it possible to implement the same thing than the jQuery code below in PHP?

I use it to hide errors made during importing products from wholesaler.

Here is the jQuery code I use:

jQuery(document).ready(function( $ ){

    $('.woocommerce-product-details__short-description:has(p:nth-of-type(2)) p').addClass('ukryj-klase-krotki');

});

How does it work:

jQuery checks if in product short description is more than one <p> element. If there is more - it adds class 'ukryj-klase-krotki' to all <p> elements. Then I add CSS class to hide first <p> element generated in product short description so the only one I want is visible:

CSS code:

.woocommerce-product-details__short-description .ukryj-klase-krotki{

    display: none;

}



.woocommerce-product-details__short-description .ukryj-klase-krotki ~ .ukryj-klase-krotki{

    display: block;

}

Any help?

My Answer:
paragraph element (p:nth-of-type(2)). If it finds more than one paragraph element, it adds a class 'ukryj-klase-krotki' to the paragraph elements.

In PHP, you can achieve a similar functionality by using DOMDocument and DOMXPath to parse the HTML content and add the class to the elements. Here is an example code snippet:

php
$html = '

Paragraph 1

Paragraph 2

';

$dom = new DOMDocument();
$dom->loadHTML($html);

$xpath = new DOMXPath($dom);

$paragraphs = $xpath->query('//div[contains(@class, "woocommerce-product-details__short-description")]/p');

if ($paragraphs->length > 1) {
foreach ($paragraphs as $paragraph) {
$paragraph->setAttribute('class', 'ukryj-klase-krotki');
}
}

$newHtml = $dom->saveHTML();

echo $newHtml;


This code snippet loads the HTML content into a DOMDocument, uses DOMXPath to query for paragraph elements within the specified class, and adds the class 'ukryj-klase-krotki' to the paragraph elements if there are more than one. Finally, it outputs the modified HTML content.
