insert code question..

cowboysdude · January 29, 2011

I am showing Youtube videos on my site and am pulling the data in from an xml file... However this is the problem I'm having...

When I pull in the video the output is working correctly until you get the image file... it's HUGE... NOT what I wanted so I set about trying to figure out how to resize the image... I have tried many things but no luck. I don't have access to the google api to change the picture size sooooo... I"m trying to do so within the php I do have..here is what I have...

$videos[$i]['img'] = $matches[0];

That output shows the HUGE picture....

Here is what I've tried to do ...

$videos[$i]['img'] = $matches[0] "width=100px height=100px";

That is a no go... it crashes the site and I know it's a quote thing.. I do know that the first example outputs the image... or puts the img in a string to be output according to the video, I understand that. How do I resize the img to make it smaller?

Here is the entire code for the parsing of the xml file....

Thanks guys!! Again!

Why does

$videos[$i]['img'] = $matches[0] "width=100px height=100px";

Have no concatenation element?

$videos[$i]['img'] = $matches[0]."width=100px height=100px";

Does that help at all? Because running the first one through PHP will cause an error regardless.

It runs but does not return the results I was hoping. I guess I'm just not getting it because I cannot seem to resize that picture down to the size I want.. it just keeps returning with the huge picture from xml...

At least now it's returning this...

<img alt="" src="http://i.ytimg.com/vi/xxwxMX7doDU/0.jpg">width=100px height=100px

Which is getting the sizes in there, just not in the correct place to be recognized.

SO here is the line as it is now [Thank you for the help!] but I need to move the width, height into the brackets somehow ....

$videos[$i]['img'] = $matches[0]."width=100px height=100px";

WOW I am just brain dead on this one... I am having a rough time LOL

Would this help you at all.

instead of squishing the pic try this

$ratioh = $max_height/$height;
$ratiow = $max_width/$width;
$ratio = min($ratioh, $ratiow);
$width = intval($ratio*$width);
$height = intval($ratio*$height);

as for hyperlinking or displaying an image this way is easy

echo "<a href='$href_location'><img src='$img_src' WIDTH='$width' HEIGHT='$height' border='0'></a><br/>";

I agree with quickoldcar, in general I've found it better to just save the URL location of the image so you can format it however afterwards. Though for your case this would probably work as well:

$videos[$i]['img'] = str_replace(">", "width=100px height=100px", $matches[0]);

However, as width/height attributes in an img tag, pixels don't need to specified I believe, that's more of a css thing. I could be wrong though.

cowboysdude · January 29, 2011

Thank you both!! YES both would work!!

I can't still control the ratio either way.. instead of using 100px I can just use 50% or whatever number I choose!

You guys are live savers!!! I REALLY REALLY appreciate your help!!!

Thank you it's working!
