如何获取对话框输入到PHP

Question

When a user wants to delete a row from a database via my webpage, I want to prompt a message-box asking, "Are you sure you want to delete?". Then in my php code, I want to track if the user press Ok or Cancel and execute the delete operation as shown bellow. I am new to web-programming and any help would be appreciated.

<?php
.
.
.

if (user wants to delete a row from database) 
{
    echo "<script type=\"text/javascript\"> confirm(\"Are you sure you want to delete?\"); </script>";
    if(user press OK to delete")//How can I get input from the dialog box?
    {
        $deleterow = "DELETE FROM ElectronicShop WHERE WorkOrder = $i";
        $datadelete = sqlsrv_query($connectString, $deleterow) or die(print_r(sqlsrv_errors(SQLSRV_ERR_ALL), true));
        if($datadelete)
            echo "<br>you have deleted: $i Successfully";       
        else 
            echo "<br>could not be deleted: $i";
    }
    else
        echo "User pressed Cancel";
}

?>

You can simply add the question to your onclick event

<a href="..." onclick="return confirm('are you sure?')">...</a>

or with jquery

<a href=".." class="delete-confirm">...</a>

$(".delete-confirm").click(function(e) {
    if (!confirm("are you sure"))
        e.preventDefault();
});
