How Can I Call A Function With A Href?

I´m trying to call a function into a href, my function is on functions.php and my href is on views/something.php so, this is my function: function discount($connection, $us){

Solution 1:

You'll need to change this to use an ajax call or form post to call the PHP function.

Here's a really basic example which should point you in the right direction

discount.php

<?php// Load $connection from somewhere// Get user, it's better to get this from a cookie or session rather than GET$user = $_GET['user']

    $discount = $connection->prepare("UPDATE postule SET seen = 1 WHERE id = :user");
    $discount->bindParam(':user', $user);
    $result = $discount->execute();

    // Throw error if something went wrong with the update, this will cause $.ajax to use the error functionif (!$result) {
        http_response_code(500);
    }

html, assuming $notu[0] contains the user id

<?phpforeach ($total_notuas$notu) : ?><li><aonClick="return callDiscount('<?phpecho"$notu[0]"; ?>');"href="#"> Notificaciones <spanclass="badge "><?phpecho"$notu[0]"; ?></span></a></li><?phpendforeach; ?>

js, requires jquery

functioncallDiscount(user_id)
{
    // Perform ajax call to discount.php
    $.ajax({
        url: '/discount.php?user=' + user_id, 
        error: function() {
            alert('An error occurred');
        },
        success: function(data) {
            // Redirect user to notificaciones.phpdocument.location = '/notificaciones.php';
        }
    });

    // Prevent link click doing anythingreturnfalse;
}
