<label>Artist </label>
<input type="text" id="ByArtist" name="ByArtist" placeholder="artist name…">
<label>Musical Group</label>
<input type="text" id="GroupName" name="GroupName" placeholder="Type something…">
<label>Poster link</label>
<input type="text" id="URL" name="URL" placeholder="Type something…">
</fieldset><br>
<input type="submit" class="btn btn-success" value="Post video">
</form>

Answer 1

Its a couple of problems, maybe more:
You have isset($_POST['VideoDate']) in your if condition which will always be false since VideoDate is not in your form. You should take this out since you seem to want to set it using CURDATE() in your insert script.
your insert statement is incorrect. mysql inserts typically look like INSERT INTO TABLE_NAME (COL1, COL2) values('VALUE1', 'VALUE2'); so you should change your insert code to look like
$sql = 'INSERT INTO videoclip (VideoTITLE, ByArtist, GroupName, URL, VideoDate) values (:VideoTITLE, :ByArtist, :GroupName, :URL, CURDATE())';

Answer 2

Your syntax is incorrect for INSERT. It should be something like:
$sql = 'INSERT INTO videoclip (VideoTITLE, ByArtist, GroupName, URL, VideoDate)
VALUES (:VideoTITLE, :ByArtist, :GroupName, :URL, CURDATE())';
In addition, $_POST['VideoDate'] is not valid as you do not have it in your form.

Answer 3

You're doing the if statements wrong.
if (isset($_POST['VideoTITLE']) && isset($_POST['ByArtist']) && isset($_POST['GroupName'])
&& isset($_POST['URL']) && isset($_POST['VideoDate'])) {
....
}
This is basic programming stuff, so you might want to get a good introductory book to programming or PHP.
