Loop / insertion image - php

Question

I'm trying to insert images into mysql. The script currently insert one image.
I have put that in the form: name="uploadImage[]" (to make an array).
I understand something is wrong in my code.
I appreciate any help and thank you in advance! :)
<?php
if (isset($_POST['btnSubmit']))
{
$uploaded_images = array();
foreach($_FILES['uploadImage']['name'] as $key=>$val)
{
$upload_dir = "uploads/";
$upload_file = $upload_dir . $_FILES['uploadImage']['name'][$key];
$filename = $_FILES['uploadImage']['name'][$key];
if (move_uploaded_file($_FILES['uploadImage']['tmp_name'][$key], $upload_file))
{
$uploaded_images[] = $upload_file;
$img0 = $filename[0];
$img1 = $filename[1];
$img2 = $filename[2];
$img3 = $filename[3];
$img4 = $filename[4];
echo $filename."<br />";
$created = date("Y:m:d h:i:s");
global $bdd;
$stmt= $bdd->prepare("INSERT INTO annonces_pro(id,ref_member,titre,intro,texte,activite,country,favorite,valid,is_ribbon,date_inserted)
VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");
$inserted = $stmt->execute(array('',$ref_member,$titre,$intro,$texte,$activite,$country,'','',$is_ribbon,$created));
$lastId = $bdd->lastInsertId();
global $bdd;
$stmt2 = $bdd->prepare("INSERT INTO annonces_pro_images(id,ref_member,image,is_cover,weight_image,date_published)
VALUES(?,?,?,?,?,?)");
$inserted2 =$stmt2->execute(array($lastId,$ref_member,$filename,'','',$created));
if ($inserted)
{
?>
<div class="alert alert-success" role="alert">
ok<br />
Insert another ad<br />
Back to homepage<br />
</div>
<?php
} else
{
?>
<div class="alert alert-danger" role="alert">Database error</div>
<?php
}
}
}
}
?>

Answer 1

removed global $bdd; as we are already in global scope, we don't need them
moved prepare statements out of the loop, as they only need to be prepared once.
added is_uploaded_file check to check if it's actually an uploaded file.
removed $img..=$filename[..]
changed foreach($_FILES['uploadImage']['name'] as $key => $file to foreach($_FILES['uploadImage'] as $file
for a better and secure version
<?php
if (isset($_POST['btnSubmit']))
{
$stmt= $bdd->prepare("INSERT INTO annonces_pro(id,ref_member,titre,intro,texte,activite,country,favorite,valid,is_ribbon,date_inserted) VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");
$stmt2 = $bdd->prepare("INSERT INTO annonces_pro_images(id,ref_member,image,is_cover,weight_image,date_published)
VALUES(?,?,?,?,?,?)");
$uploaded_images = array();
foreach($_FILES['uploadImage'] as $image)
{
$filename = $image['name'];
if (!is_uploaded_file($filename)) continue;
$upload_dir = "uploads/";
$upload_file = $upload_dir . $image['name'];
if (move_uploaded_file($image['tmp_name'], $upload_file))
{
$uploaded_images[] = $upload_file;
echo $filename."<br />";
$created = date("Y:m:d h:i:s");
$inserted = $stmt->execute(array('',$ref_member,$titre,$intro,$texte,$activite,$country,'','',$is_ribbon,$created));
$lastId = $bdd->lastInsertId();
$inserted2 =$stmt2->execute(array($lastId,$ref_member,$filename,'','',$created));
if ($inserted)
{
?>
<div class="alert alert-success" role="alert">
