My HTML:
<h1>Upload image</h1>
<p>
<span class="notification">Use shift+click or ctrl+click to select multiple images at once. <br /></span>
</p>
<p>Only <span class="emp">*.png, *.jpeg, *.jpg, and *.gif</span> filetypes are allowed.<br /></p>
<form action= "<?PHP echo "upload.php?adr=" . $_POST["formFeast"]; ?>" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="userfile[]" id="userfile" multiple="multiple" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>
<p><a href="admin-dashboard">Back to admin dashboard</a></p>
Most of the time it works great. However, when uploading lots of files at the same time, I get "Wrong File Type" as an output. and only 1 "Wrong file type", not multiple.
Does this have to do with GD?
