How to disable specific JS file for a specific PHP file?

Opting for the conditional loading of a script is preferable to unloading it after it has been loaded.

Conditional loading goes like this:

1. Check for the existence of a function that may cause conflict.
2. Load the script into if there are no conflicts detected.

To check for the existence of an opposing script, verify if any of its functions are activated. For instance, if your conflicting code contains a function called naughtyFn() , it will load jQuery unless naughtyFn() is already present.

// load jQuery, unless conflicting script exists function loadJQ(conflictFName) < if (typeof window[conflictFName] === 'function') < return alert(`can't load jQuery, conflicts with $`); > // create script tag and load into const jqScript = document.createElement('script'); jqScript.src = 'https://code.jquery.com/jquery-3.5.1.slim.min.js'; document.body.appendChild(jqScript); setTimeout(() => < console.log(`window.jQuery: $`); >, 1000); >// load a conflicting script function loadConflict() < const conflictScript = document.createElement('script'); conflictScript.innerHTML = 'function naughtyFn() <>'; document.body.appendChild(conflictScript); setTimeout(() => < console.log(`window.naughtyFn: $`); >, 1000);>

 Load conflicting script Try to load jQuery 

To ensure the conflict test functions properly, the naughtyFn should be pre-loaded. Waiting until window.onload to execute the conflict test would be a wise decision.

Как добавить код php в скрипт jquery?

Extremo,
PHP здесь не нужен, селектор #payment_method срабатывает по клику, значит и при изменении значения на rbspayment у поля е-мейл будет атрибут required, для стальных значений атрибута required не будет.
Вы будете по клику на #payment_method подгружать php ?

Либо делайте тогда всё на PHP, либо на jquery

Extremo,
Через php вам придется перезагружать страницу при изменении способа оплаты, чтобы добавить атрибут required, через jquery перезагрузка не понадобится, атрибут required добавится или уберётся в зависимости от способа оплаты!

P/S: если через php то jquery код вам вообще не нужен, скрывайте и отображайте поле e-mail также через php 🙂

Spartak (Web-StyleStudio), интересная картина получилась. Код работает, с поля снимается атрибут requared при выборе метода. Но функционал woocommerce игнорирует прописанный js и либо для всех ставит email обязательным, либо наоборот.

Если у вас на сайте селекторов с таким идентификатором #billing_email более чем один, то jquery сработает только у первого найденного, так как идентификатор по правилам должен быть только один (в вашем случае это «#billing_email»). Чтобы jquery код работал только для формы оплаты вам в самой этой форме оплаты надо сделать уникальные идентификаторы для поля e-mail, например «#billing_email_new». Ну и соответственно в коде jquery заменить на «#billing_email_new».
Для более полной картины не хватает html кода формы оплаты!

Как и писал выше, либо на php всё делать либо на jquery

Spartak (Web-StyleStudio), По коду видно, что при смене метода оплаты добавляется и удаляется атрибут requared, но форма работает через woocomerce и проверку введенных полей проверяет тоже woocommerce
