How Can I Keep Dropdown Selections Persistent After Form Submission in WordPress?

Keeping Selections Persistent on Form Submission in WordPress

When submitting forms, maintaining the selected values in dropdowns is crucial for user-friendliness. This becomes especially relevant in WordPress, where forms often reside within complex themes and plugins.

Consider the following form:

<form method="get" action="">
   <select name="name">
      <option value="a">a</option>
      <option value="b">b</option>
   </select>
   <select name="location">
      <option value="x">x</option>
      <option value="y">y</option>
   </select>
   <input type="submit" value="Submit">

For example, if a user selects "a" and "x" in the name and location dropdowns, we want these selections to persist even after submitting the form. To achieve this in WordPress, we can harness the power of JavaScript:

<select name="name">

This code assigns the selected values to the corresponding dropdown elements using JavaScript. By leveraging PHP, we retrieve the GET parameters submitted by the form, allowing us to dynamically update the dropdown values.

This solution eliminates the need for complex if-else statements and ensures that the selected values remain intact after form submission, enhancing the user experience.
