如果从数据库中单击“确定更新2”行，则发出警报，否则不执行任何操作

Question

i have a problem, i have a script that when i click a button it update data on database, but also display an alert. what im trying to do is, if i click "OK" on the alert it must update or insert (if there is no data) new data (on row statuscomanda and statuscomandatapiterii = "EXPEDIAT"). if i click cancel do nothing

this is what i got, i got the connection to the database.

<script>
function loaded()
{
if (confirm('A fost livrata comanda?')) { 
// Save it!
} else {
// Do nothing!
}
window.setTimeout(CloseMe, 200);
}

function CloseMe() 
{
window.close();
}
</script>

i have tryed this:

<script>
function loaded()
{
if (confirm('A fost livrata comanda?')) <?php $sql = "UPDATE $table SET 
statuscomanda='expediat' statuscomandatapiterii='expediat' WHERE id=$id"; 
?> { 
// Save it!
} else {
// Do nothing!
}
window.setTimeout(CloseMe, 200);
}

function CloseMe() 
{
window.close();
}
</script>

i tought if i add this, it should do the job

if i click ok just update or add (if there is no data in the specific row) , the data updated should be "expediat" if i click cancel do nothing :)

EDITED!!

i have tried this ,

function confirmDelete() {
    if (confirm('Doresti sa schimbi in expediat?')) {
        //Make ajax call
        $.ajax({
            url: "test2.php",
            type: "POST",
            data: {id : 5},
            dataType: "html", 
            success: function() {
                alert("A fost schimbat in expediat");
            }
        });

    }
}

used external php file nammed test2.php , that file change the data into database, but still not working if i press the yes button

Answer 1

First off PHP will always get executed before the page load, so in other words you can't call PHP from javascript functions.

That said you can call PHP routes from javascript functions using AJAX. Either that or you use javascript to submit a form to a php script.

Those are really your 2 options.
