Insert Data within a loop and echo only once - php

Question

i have a php script with a sql query that is inside a foreach loop and if the query succeed to run it should echo "Success" but since its inside a loop it echo "success" multiple times but i wish to only echo "success" once. I have seen other similar threads here and i have looked at those and tried solve my problem from those threads but i have not been able to solve this problem from any other threads so please dont mark this as a duplicate.
Anyway, Here is my code
<?php
session_start();
include('../../config/dbconf.php');
foreach($_POST['entry'] as $entryid) {
$stmt = $authconn->prepare("UPDATE account SET dp = dp - ? WHERE username = ?");
$stmt->bind_param("is", $_POST['price'], $_SESSION['classicusr']);
if($stmt->execute()) {
echo "Success";
}else{
echo "Failed";
}
}
?>

Answer 1

You could try something like this?
Also, there is no need to prepare for each iteration of the loop.
<?php
session_start();
include('../../config/dbconf.php');
$bError = false;
$authconn->prepare("UPDATE account SET dp = dp - ? WHERE username = ?");
foreach($_POST['entry'] as $entryid) {
$stmt = $stmt->bind_param("is", $_POST['price'], $_SESSION['classicusr']);
try{
if(!$stmt->execute()) {
$bError = true;
// optional break and do not process further
// break;
$stmt = $stmt->errorInfo()
}
}catch (PDOException Exception){
$bError = true;
// additional erorr logging here. Could add to a delimetered string to report on later } }
echo ($bError ? 'Failure' : 'Success' );
?>

Seeing as you're not saying anything about the Failed statement, something like this might do the trick. All it requires is setting a simple flag.
<?php
session_start();
include('../../config/dbconf.php');
$feedbackGiven = FALSE;
foreach($_POST['entry'] as $entryid) {
$stmt = $authconn->prepare("UPDATE account SET dp = dp - ? WHERE username = ?");
$stmt->bind_param("is", $_POST['price'], $_SESSION['classicusr']);
if($stmt->execute()) {
if (!$feedbackGiven)
{
echo "Success";
$feedbackGiven = TRUE;
}
}else{
echo "Failed";
}
}
?>
