How to explode in 2 places.

http://www.youtube.com/watch?v=BTPTrOfaN0U&feature=related

How can I explode the parts in red?

All I want is the video id.

Also, what happens if there is no &feature=related ?

Will adding code to remove it break?

 

Removing "&feature=related" will not effect it at all.

 

I can code a script for you that will extract the video ID. Drop me a PM.

 

This is what I have so far:

<?php
$str = "http://www.youtube.com/watch?v=BTPTrOfaN0U&feature=related";
print_r (explode("v=",$str));
print_r (explode("&",$str));
?> 		

Code (markup):

How can I remove the part before v= and the part after & ?

Can I say like explode <= or explode =>

How does that work?

 

Kind of sloppy, but here you go:

$str = 'http://www.youtube.com/watch?v=BTPTrOfaN0U&feature=related';
$str_temp = explode('v=',$str);
$str_temp = explode('&feature',$str_temp[1]);
$str = $str_temp[0];

Code (markup):

Not tested.

 

I actually figured it out by searching on google for:

"remove domain and string from a url"

Then I found:

http://www.astahost.com/index.php?showtopic=15518&view=findpost&p=102612

Then I modified it for myself

Then I wrote:

<?php
$original_url = "http://www.youtube.com/watch?v=BTPTrOfaN0U&feature=related";
$split_url = explode('v=', $original_url);
$split_url_again = explode('&', $split_url[1]);
$youtube_video_id = $split_url_again[0];
echo $youtube_video_id;
?> 		

Code (markup):

The code I made is very similar to yours -- but longer and sloppier - lol

Thanks Kimochi

 

No problem. Please add to my reputation if I was at all helpful

 

oh.. okies

 

I am looking everywhere for a reputation link -- where is it?

 

I found it!

 

I have one problem..

I need to detect whether $original_url contains youtube.com -- as it is not coded into the site, $original_url actually comes from a form.

How do I go about saying something like (and don't laugh at my explanation)...

if ( url contains youtube.com ) {
I put my regular code here
}
else {
ENTER A YOUTUBE URL!
}

?

 

Why PM? Are you gonna charge him for one line of code?

Anyway, forget these ugly explodes. This will do all in one...

if (preg_match('~^http://(?:[a-z]{2,3}\.)?youtube\.com/watch\?v=([\w-]+)~', $original_url, $match))
{
    echo $match[1];
}
else
{
    echo 'Invalid URL.';
}

thanks nico_swd

I kinda have to stick with what I made, because look - it's already such a mess lol

Code (markup):

Yeah -- as you can tell, programming isn't my forte

Nope, I am "the" MrLeN online. I own the dot com -- so there you go lol.

 

I know I could probably do some fancy loop or something, but I am lucky to be able creating what I am creating with what skills I have lol. I will post a link to the script I am making just as soon as I am a little bit more happy with it. It might be coded like a dogs breakfast (and I'm not even joking).. but it's a way cool script Does the job!

 

Oh my... haha.

Use arrays!!! Name your input fields like this:

<input type="text" name="v[]" />

Code (markup):

... rather than the number things. And then use a loop in your PHP code:

foreach ((array)$_POST['v'] AS $v)
{
    echo $v;
    // Split $v or whatever you want to do with it.
}

PHP:

... that'd make it slightly shorter lol.

 

wow..

go with nico_swd's suggestion, and put it in a loop...

$numFields    = 20;
$originalUrls = array();

for ($i = 0; $i < $numFields; $i++) {
    $field = "v{$i}";
    
    if (preg_match('~^http://(?:[a-z]{2,3}\.)?youtube\.com/watch\?v=([\w-]+)~', $_POST[$field], $match)) {
        $originalUrl[$field] = $_POST[$field];    
    } else {
        $originalUrl[$field] = 'EMPTY';
    }
}

PHP:

 

Do I have to put something inside v[HERE] ?

 

No, just put it as 'v[]'.

<form>
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
    <input type='text' name='v[]' />
</form>

PHP:

Once the form posts, you will have this array.

$_POST['v'][0] = 'some_url';
$_POST['v'][1] = 'some_url';
$_POST['v'][2] = 'some_url';
$_POST['v'][3] = 'some_url';
etc...

PHP:

$numFields    = 20;
$originalUrls = array();

for ($i = 0; $i < $numFields; $i++) {
    if (preg_match('~^http://(?:[a-z]{2,3}\.)?youtube\.com/watch\?v=([\w-]+)~', $_POST['v'][$i], $match)) {
        $originalUrl[$i] = $match[1];
    } else {
        $originalUrl[$i] = 'EMPTY';
    }
}

PHP:

However, I would not do a foreach loop on $_POST['v'] as nico's code above does, as it is not very secure.
A user could copy the form to their own server, and create thousands of fields, and post it back to your script which will get stuck parsing it all =)

Specifying the expected field count (as in my reply above) will prevent that situation.

 

okies, that does look a lot cleaner.. I'll have a play around and see if I can get it working that way.. I'll come back and let you know how I go. Thanks heaps for the explanation.

I just registered the domain for this script right now

I'll upload it and you can see what it does. It's pretty cool

 

I personally would use regex if I were you, Nico already gave you a pattern for it, saves many lines of code and a headache if you have to look back on it.
