multiple image upload how to make it? - php

Question

I have a code which works fine if I want to upload one image into my MySQL and server.
PHP code:
if(isset($_POST['btnsave']))
{ foreach($_FILES['user_image']['tmp_name'] as $key => $tmp_name ){
$username = $_POST['user_name'];
$userjob = $_POST['user_job'];
$imgFile = $key.$_FILES['user_image']['name'][$key];
$tmp_dir = $_FILES['user_image']['tmp_name'][$key];
$imgSize = $_FILES['user_image']['size'][$key];
}
if(empty($username)){
$errMSG = "Please Enter Username.";
}
else if(empty($userjob)){
$errMSG = "Please Enter Your Job Work.";
}
else if(empty($imgFile)){
$errMSG = "Please Select Image File.";
}
else
{
$upload_dir = 'user_images/';
$imgExt = strtolower(pathinfo($imgFile,PATHINFO_EXTENSION));
$valid_extensions = array('jpeg', 'jpg', 'png', 'gif');
$userpic = rand(1000,1000000).".".$imgExt;
if(in_array($imgExt, $valid_extensions)){
if($imgSize < 5000000) {
move_uploaded_file($tmp_dir,$upload_dir.$userpic);
}
else{
$errMSG = "Sorry, your file is too large.";
}
}
else{
$errMSG = "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
}
}
if(!isset($errMSG))
{
$stmt = $DB_con->prepare('INSERT INTO tbl_users(userName,userProfession,userPic) VALUES(:uname, :ujob, :upic)');
$stmt->bindParam(':uname',$username);
$stmt->bindParam(':ujob',$userjob);
$stmt->bindParam(':upic',$userpic);
if($stmt->execute())
{
$successMSG = "new record successfully inserted ...";
header("refresh:5;index.php");
}
else
{
$errMSG = "error while inserting....";
}
}
}
Html code:
<?php
if(isset($errMSG)){
?>
<div class="alert alert-danger">
<span class="glyphicon glyphicon-info-sign"></span> <strong><?php echo $errMSG; ?></strong>
</div>
<?php
}
else if(isset($successMSG)){
?>
<div class="alert alert-success">
<strong><span class="glyphicon glyphicon-info-sign"></span> <?php echo $successMSG; ?></strong>
</div>
<?php
}
?>
<form method="post" enctype="multipart/form-data" class="form-horizontal">
<table class="table table-bordered table-responsive">
<tr>
<td><label class="control-label">Username.</label></td>
<td><input class="form-control" type="text" name="user_name" placeholder="Enter Username" value="<?php echo $username; ?>" /></td>
</tr>
<tr>
<td><label class="control-label">Profession(Job).</label></td>
<td><input class="form-control" type="text" name="user_job" placeholder="Your Profession" value="<?php echo $userjob; ?>" /></td>
</tr>
<tr>
<td><label class="control-label">Profile Img.</label></td>
<td><input class="input-group" type="file" name="user_image[]" accept="image/*" multiple /></td>
</tr>
<tr>
<td colspan="2"><button type="submit" name="btnsave" class="btn btn-default">
<span class="glyphicon glyphicon-save"></span> save
</button>
</td>
</tr>
</table>
</form>
How can I make it code to use for multiple upload? For all images which I would upload I would make the same values except 'userPic'- the same name for a file at my server. Can you help me out please?

Put everything inside the foreach block.
if(isset($_POST['btnsave']))
{ foreach($_FILES['user_image']['tmp_name'] as $key => $tmp_name ){
$username = $_POST['user_name'];
$userjob = $_POST['user_job'];
$imgFile = $key.$_FILES['user_image']['name'][$key];
$tmp_dir = $_FILES['user_image']['tmp_name'][$key];
$imgSize = $_FILES['user_image']['size'][$key];
if(empty($username)){
$errMSG = "Please Enter Username.";
}
else if(empty($userjob)){
$errMSG = "Please Enter Your Job Work.";
}
else if(empty($imgFile)){
$errMSG = "Please Select Image File.";
}
else
{
$upload_dir = 'user_images/';
$imgExt = strtolower(pathinfo($imgFile,PATHINFO_EXTENSION));
$valid_extensions = array('jpeg', 'jpg', 'png', 'gif');
$userpic = rand(1000,1000000).".".$imgExt;
if(in_array($imgExt, $valid_extensions)){
if($imgSize < 5000000) {
move_uploaded_file($tmp_dir,$upload_dir.$userpic);
}
else{
$errMSG = "Sorry, your file is too large.";
}
}
else{
$errMSG = "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
}
}
if(!isset($errMSG))
{
$stmt = $DB_con->prepare('INSERT INTO tbl_users(userName,userProfession,userPic) VALUES(:uname, :ujob, :upic)');
$stmt->bindParam(':uname',$username);
$stmt->bindParam(':ujob',$userjob);
$stmt->bindParam(':upic',$userpic);
if($stmt->execute())
{
$successMSG = "new record succesfully inserted ...";
header("refresh:5;index.php");
}
else
{
$errMSG = "error while inserting....";
}
}
}}
