How to refresh a page in jquery file after updating certain values?

Question

I have populated a table from database using php and updating its values using js(ajax jquery) Record updates perfectly, I am calling page reload function to get updated values but reload() function is not working. Here is the code

I am calling model to update values in db. Loadfunction() populates the values in model and onclick() event invokes updatedata() function in item.js

<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-hidden="true"
                    data-backdrop="static" data-keyboard="false" id="modelEditItem">
                    <div class="modal-dialog modal-lg">
                    <div class="modal-content">
                        <div class="modal-header">
                            <h5 class="modal-title">Edit From</h5>
                            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                                <span aria-hidden="true">&times;</span>
                            </button>

    $id=$_POST["id"];
    $name=$_POST["name"];
    $query = mysqli_query($con, "UPDATE item SET ib_name = '$name' WHERE ib_id = ".$id);
    //$result= mysqli_query($con,$query);
    if ($query)
    {
        ?>  
        <script>
        console.log($query);
        window.location.replace('item_2.php');
       </script>
       <?php
    }
    mysqli_close($con);
    //echo "updated";
    ?>

Can you show us the HTML part and where you call updateItem() please ? Is console.log(result); working ? — Camille

is console.log('result') even running ? because window.location.reload() is right code to reload page problem seems like its not getting triggered by ajax your ajax is maybe failing — Amir Rahman

return a value from php done or failed according to $query state then read it in javascript and run code with matching condition

try this way

php

<?php
    include 'connection.php';
    $id=$_POST["id"];
    $name=$_POST["name"];
    $result = ""; // edited line
    $query = mysqli_query($con, "UPDATE item SET ib_name = '$name' WHERE ib_id = ".$id);
    //$result= mysqli_query($con,$query);
    if ($query){
        $result = "done"; // edited line
    }
    else{
        $result = "failed"; // edited line
    }
    mysqli_close($con);
    echo $result; // edited line
?>

js

function updateItem() {
    var id= document.getElementById("et_id").value;
    var name = document.getElementById("et_name").value;
    // console.log(id, name);
    $.ajax({
        url: "update_item.php",
        type: "POST",
        data: {id,name},
        success: function (result) { 
            console.log("working") // debuggin
            if(result == "done"){window.location.href="item2.php"}
        }
    });
}
