display thumbnails of products on shop page.

Question

My code has many lines, hence im not going to paste everything , just the important parts.

I dont feel confident as to the way i achieved the task of displaying the thumbnail on the shop page. Hence , can someone let me know if how i did what i did is okay or not?

I have a simple form :

<center>
<form method="POST" action="" enctype="multipart/form-data">
<center>
<label>Thumbnail:</label><br><input type="file" name="thumbnail"><br><br>
<input type="submit" name="submitThumbnail" value="upload thumbnail" formaction="shop.php">
</form>

Then i have the following php in my shop page:

<?php

if(isset($_POST['submitThumbnail'])){
$file = $_FILES['thumbnail'];

$fileName = $_FILES['thumbnail']['name'];
$fileTmpName = $_FILES['thumbnail']['tmp_name'];
$fileSize = $_FILES['thumbnail']['size'];
$fileError = $_FILES['thumbnail']['error'];
$fileType = $_FILES['thumbnail']['type'];

$fileExt = explode('.',$fileName);
$fileActualExt = strtolower(end($fileExt));

$allowed = array('jpg' , 'jpeg' , 'png' , 'pdf');

if(in_array($fileActualExt,$allowed)){
if($fileError === 0){
if($fileSize<1000000){
$fileNameNew = uniqid('',true).".".$fileActualExt;
$fileDestination = 'uploads/'.$fileNameNew;
move_uploaded_file($fileTmpName, $fileDestination);

}else{
echo "Your file is too big!";
}
}else{
echo "There was an error uploading the file";
}
}else{
echo "You cannot upload files of this type!";
}
}

?>

<?php $myFile = fopen('shop.php','a+'); //open shop file and allows me to add code to it through php
$newsneakerImage = "<a"." "."href='https://www.sololearn.com/Discuss?ordering=MostRecent'>"."<img"." "."id=newSneaker"." "."src=".$fileDestination." "."height=250"." "."width=250>"."</a>";
fwrite($myFile,$newsneakerImage);
fclose($myFile);
?>

I just want to add, the code does display the images but its has some defects which i am looking into solve with jquery etc. Is my code okay?

Answer 1

Could you publish the code on the Code Editor so we see how it runs??
