How to stop sending $_FILES['name'] if nobody provides thefile? - php

Question

I Have a multipart/form-data form but I not require from users to send me the picture. I am changing the name of the file to random number and the put the path to MySQL. Whenever somebody doesn't put the file, in my database a new recor is beeing created without an extension(obviesly). How to stop this from happening?
Sorry for my english.
Here is a a part from the code:
case 'Sleep Aid': {
?>
<section class="summarySection">
<div class="summaryHeadingDIV">
<h1 class="summaryH1">Please check the details below</h1>
</div>
<article class="summaryPage">
<p class="boldSummaryDescr">Brand:</p><p class="paraSummary"><?php echo $brand; ?></p><br>
<p class="boldSummaryDescr">Model:</p><p class="paraSummary"><?php echo $model; ?></p><br>
<p class="boldSummaryDescr">Colour:</p><p class="paraSummary"><?php echo $colour; ?></p><br>
<p class="boldSummaryDescr">Material:</p><p class="paraSummary"><?php echo $material; ?></p><br>
<p class="boldSummaryDescr">Suitable Age:</p><p class="paraSummary"><?php echo $suitable; ?></p><br>
<p class="boldSummaryDescr">Purchase date:</p><p class="paraSummary"><?php echo $month . '/' . $year; ?></p><br>
<p class="boldSummaryDescr">Condition:</p><p class="paraSummary"><?php echo $condition; ?></p><br>
<p class="boldSummaryDescr">Dimesions:</p><p class="paraSummary"><?php echo $width . ' cm <span class="smallcaps">x</span> ' . $height . ' cm <span class="smallcaps">x</span> ' . $depth . ' cm'; ?></p><br>
<p class="boldSummaryDescr">Weight:</p><p class="paraSummary"><?php echo $weight . ' kg'; ?></p>
</article>
<div class="imageg_container">
<figure class="img_figure_show">
<?php
if(empty($picture))
{

<img src="/_images/no-picture.png" alt="no picture added">

}
else
{
$random_id = rand_img_id();
add_file(db_user_connect(), $email, $random_id);
$arry = show_picture(db_user_connect(), $email, $random_id);

You need to check the $_FILES['error'] value:
if ($_FILES['name']['error'] === UPLOAD_ERR_OK) ...
The manual lists all possible values, which you could use to display different messages/do different things: https://secure.php.net/manual/en/features.file-upload.errors.php
