使用AJAX和重定向将表单值传递给PHP变量

Question

Is it possible for a user to enter a value into a form and then, on submit, have the page redirect to a new one with the value entered into the form stored in a PHP variable?

This if my form code;

<form id="loc-search" method="post">

    <input type="text" id="search-by-location" name="custom-location" value="" placeholder="Sheffield, UK"/>

    <input type="submit" id="submit" value=""/>

</form>

Once the user has entered a value in #search-by-location the page needs to redirect to weather.php with the value stored in a PHP variable called $location

AJAX / JS aren't my strong suits so if someone could point me in the right direction that would be great

Answer 1

Add the argument action="weather.php" to your form tag. Then, when clicked on the submit button, you will get redirected to that page. Depending on your method, in your case POST, the input values will be available in the superglobal $_POST array in PHP.

In your example, $location = $_POST["custom-location"]; will suffice. Note that the name, not the ID, determines the array key in the target PHP document.

Javascript or AJAX are not needed to achieve this.
