I'll post a screen shot of the profile fields in the UserCP.
Let's say your user wants to add their band's YouTube video.. or anything for that matter.
They'll get their YouTube link. Example:
http://www.youtube.com/watch?v=0f9Q7VYnLJk
Then in the profile field, they would paste the 0f9Q7VYnLJk part into the field. Then to add more videos, they just have to repeat the same step as many times as they want for however many videos you allow them to have.
If you want to place the videos in the same spot I have them, you'll first have to install the Interactive Profiles mod here
https://vborg.vbsupport.ru/showthread.php?t=150028. After you have installed that, find the following code in your MEMBERINFO template:
Code:
<td class="alt1"><center><img src="$userinfo[profilepicurl]" $userinfo[profilepicsize] alt="<phrase 1="$userinfo[username]">$vbphrase[xs_picture]</phrase>" border="0" style="border:1px solid $stylevar[tborder_bgcolor]; border-top:none" /></center></td>
</tr>
</table>
</if>
<br />
And add the code below that. Note: I have edited the Profile Pic table script to my needs, so it may differ from yours slightly.
