Change form data before I store it

[refiking]

I am working on allowing my users to paste a code snippet from You Tube on my site and store it as their "viedopic".  I already have the "videopic" coded.  What I need help with is changing the code they input before I store it to fit my parameters.  For example, here is a snippet of code from a You Tube video:

 

<object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/CoiFGva_JoY&rel=0&color1=0x5d1719&color2=0xcd311b&border=0"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/CoiFGva_JoY&rel=0&color1=0x5d1719&color2=0xcd311b&border=0" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object>

 

I'd like to change to make the following changes on the fly (before I add it to the db):

 

1) Change width to 400

2) Change height to 400

3) Replace everything from the "&" to the quotes with this:

 

&autoplay=1&rel=0&color1="black"&color2="black"

you can use str_replace or preg_replace

what you should do is just have the user post the url instead of the the hole <object> that why you are in control of everything that happens in the object parameter, then all you need to do is call the url

 

$url = $row['url'];

<object value='$url'></object>

OK.  Thanks!
