PHP foreach video in file

[JesseToxik]

Hello all,

 

I'm new to PHP and in a bit of a jam. I have a PHP script that scans a specified folder for all the files in it. All of the files are images. It uses a foreach statement to place them all inside of hyperlinks linked to lightbox to make an image gallery. This works perfectly. Now part two of my gallery project is scanning a different file for videos. I figured it would be pretty easy to edit my existing script and conform it to video. I was wrong. Halfway through rewriting the script I realized that every video has two formats. MP4 and OGG. This will cause every video to be displayed in the gallery twice. Does anyone know how to scan a file for videos and place them on a page without making an embeded video for each format?

 

Below is my code.

<?php
$videos= glob('videos/*');
natcasesort($videos);
foreach($videos as $video) {
   echo '<video controls tabindex="0">';
   echo '<source src="'.$video.'" type="video/mp4;" />';
   echo '<source src="'.$video." type="video/ogg;" />';
   echo '</video>';
}
?>

Scan a file? You mean directory. Really confusing otherwise.

 

Build an array beforehand of the names of files and their various extensions. Like

$rawvideos = glob('videos/*.*');
natcasesort($rawvideos);
$videos = array();
foreach ($rawvideos as $file) {
    $extension = substr($file, strrpos($file, '.') + 1);
    $filenoext = substr($file, 0, strlen($extension) + 1);
    if (!isset($videos[$filenoext])) {
        $videos[$filenoext] = array();
    }
    $videos[$filenoext][] = $extension;
}

Then do your normal loop over $videos but you can check for extensions. Or go fancy and use another loop.

$types = array(
    'mp4' => 'video/mp4',
    'ogg' => 'video/ogg'
);

foreach ($videos as $filenoext => $extensions) {
    echo '<video controls tabindex="0">';
    foreach ($extensions as $extension) {
        if (isset($types[$extension])) {
            echo '<source src="' . $filenoext . "." . $extension . '" type="' . $types[$extension] . '" />';
        }
    }
    echo '</video>';
}

EDITED - So far it works except for one problem. After running the page through wampserver to preview it I get a black box saying "No video with supported format and MIME type found."[Firefox].

 

After viewing the source code this is the video line that your code is generating.

<video controls tabindex="0"><source src="vide.mp4" type="video/mp4" /><source src="vide.ogg" type="video/ogg" /></video>

 

Any idea why the video souces are vide.mp4 and vide.ogg?

I have actually found the problem but not sure how to fix it.

 

This line:

$filenoext = substr($file, 0, strlen($extension) + 1);

 

It is only allowing so much added to the source.

If I were to change that 1 to a 10 the source would go from vide.mp4 and vide.ogg to videos/traile.mp4 and videos/traile.ogg.

Any ideas?

Ah, typo.

$filenoext = substr($file, 0, -strlen($extension) - 1);

Negative number. If the extension is "ogg" then it should act like substr($file, 0, -4) (-1 for the period).

[JesseToxik]

Changing the + 1 to a - 1 gives me this in my source code.

<video controls tabindex="0"><source src="vi.mp4" type="video/mp4" /><source src="vi.ogg" type="video/ogg" /></video>

I missed the other "-" you put in there.

Seems to work. Will add another video to the directory for testing.

Works like a charm

If I wanted to add more extensions would I just edit this line?

$types = array(
    'mp4' => 'video/mp4',
    'ogg' => 'video/ogg'

[requinix]

Yep.
