How to fix Upload image using php and mysqli - php

Question

I tried replacing mysql to mysqli, but I encountered an error in this code, it worked on mysql before. What is wrong?
Php:
<?php include "../../../_includes/config.php"; ?>
<?php
session_start();
if(!empty($_FILES['userAvatar']['name'])){
$uploadedFile = "";
if(!empty($_FILES["userAvatar"]["type"])){
$filename = $_FILES['userAvatar']['name'];
$valid_extensions = array("jpeg", "jpg", "png");
$temporary = explode(".", $_FILES["userAvatar"]["name"]);
$file_extension = end($temporary);
if((($_FILES["userAvatar"]["type"] == "image/png") || ($_FILES["userAvatar"]["type"] == "image/jpg") || ($_FILES["userAvatar"]["type"] == "image/jpeg")) && in_array($file_extension, $valid_extensions)){
$sourcePath = $_FILES['userAvatar']['tmp_name'];
$targetPath = "../../../uploads/image/".$filename;
if(move_uploaded_file($sourcePath, $targetPath)){
$uploadedFile = $filename;
}
}
}
$display_name = $_POST['display_name'];
$biography = $_POST['biography'];
$sql = mysqli_query($connect, "UPDATE tb_users SET userDisplayName = '$display_name', userBiography = '$biography', userAvatar = '$uploadedFile' WHERE userLogin = '".$_SESSION['is_logged_in']['userLogin']."'") or die(mysqli_error());
if($sql){
echo "ok";
}else{
echo "err";
}
}else{
echo "err";
}
?>
Result always "err".

Answer 1

try this code:-
$sql = mysqli_query($connect, "UPDATE tb_users SET userDisplayName = '$display_name', userBiography = '$biography', userAvatar = '$uploadedFile' WHERE userLogin = '".$_SESSION['is_logged_in']['userLogin']."'") or die(mysqli_error($connect));
// no need of this
if($sql){
echo "ok";
}else{
echo "err";
}

Try this code below
<?php
$dbhost = 'localhost:3306';
$dbuser = 'root';
$dbpass = '';
$dbname = 'your db';
$conn = mysqli_connect($dbhost, $dbuser, $dbpass,$dbname);
if(! $conn ) {
die('Could not connect: ' . mysqli_error());
}
echo 'Connected successfully<br>';
session_start();
if(!empty($_FILES['userAvatar']['name'])){
$uploadedFile = "";
if(!empty($_FILES["userAvatar"]["type"])){
$filename = $_FILES['userAvatar']['name'];
$valid_extensions = array("jpeg", "jpg", "png");
$temporary = explode(".", $_FILES["userAvatar"]["name"]);
$file_extension = end($temporary);
if((($_FILES["userAvatar"]["type"] == "image/png") || ($_FILES["userAvatar"]["type"] == "image/jpg") || ($_FILES["userAvatar"]["type"] == "image/jpeg")) && in_array($file_extension, $valid_extensions)){
$sourcePath = $_FILES['userAvatar']['tmp_name'];
$targetPath = "../../../uploads/image/".$filename;
if(move_uploaded_file($sourcePath, $targetPath)){
$uploadedFile = $filename;
}
}
}
$display_name = $_POST['display_name'];
$biography = $_POST['biography'];
$sql ="UPDATE tb_users SET userDisplayName = '$display_name', userBiography = '$biography', userAvatar = '$uploadedFile' WHERE userLogin = '".$_SESSION['is_logged_in']['userLogin']."'";
if (mysqli_query($conn, $sql)) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . mysqli_error($conn);
}
mysqli_close($conn);
}else{
//echo "err";
}
?>
