I am a new learner to php. I am trying to retrieve embeded information

  • 0

I am a new learner to php. I am trying to retrieve embeded information from youtube videos URLs. I was originally following the code from this SITE but unfortunately the author doesn’t provide access to actual code.

I am having difficulties extracting the php variable values so that i can get the embedded video code.

The htmlentities echo is returning this errorsyntax error, unexpected T_CONSTANT_ENCAPSED_STRING

source: SITE

<html>
    <form method="post" action="">
    URL:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
    <input type="text" value="<?php $vari ?>" name="yurl"> <!--$vari-->
    <br>
    <br>
    Height:&nbsp;
    <input type="text" value="<?php $hth ?>" name="yheight"> <!--$hth-->
    <br>
    <br>
    Width:&nbsp;&nbsp;
    <input type="text" value="<?php $wdth ?>" name="ywidth"> <!--$wdth-->
    <br>
    <br>
    Autoplay:&nbsp;
    <input type="checkbox" value="<?php $auto1; $auto2; ?>" name="yautop">  <!--$auto1 $auto2-->
    <br>
    <br>
    <input type="submit" value="Generate Embed Code" name="ysubmit">
    </form>
</html>

php code for getting youtube url info

<?php
$vari ='';
$step1 =explode ('v=', $vari);
$step2 =explode ('&amp;',$step1[1]);

$auto1='?autoplay=1';

$auto2='&autoplay=1';


//Iframe code with autoplay
echo htmlentities ('<iframe src="http://www.youtube.com/embed/'.$step2[0].$auto1'"
frameborder="0" width="'.$wdth.'" height="'.$hth.'"></iframe>';

//embed code with autoplay
echo htmlentities ('<embed width="'.$wdth.'" height="'.$hth.'"
type="application/x-shockwave-flash" src="http://www.youtube.com/v/'.$step2[0].$auto2'"
wmode="transparent" embed="" /></embed>');
?>

    Try Below Code… Should Work

    <?php
$vari ='';

if($_POST)
{
    $vari       = $_POST['yurl'];
    $hth        = $_POST['yheight'];
    $wdth       = $_POST['ywidth'];
    $is_auto    =   0;

    $step1 =explode ('v=', $vari);
    $step2 =explode ('&amp;',$step1[1]);

    if(isset($_POST['yautop'] ))
    {
        if($_POST['yautop'] == 1)
            $is_auto    =   1;
    }
    $auto1  = '?autoplay='.$is_auto;
    $auto2  = '&autoplay='.$is_auto;

//Iframe code with autoplay

echo htmlentities ('<iframe src="http://ww.youtube.com/embed/'.$step2[0].$auto1.'" frameborder="0" width="'.$wdth.'" height="'.$hth.'"></iframe>');

//embed code with autoplay
echo htmlentities ('<embed width="'.$wdth.'" height="'.$hth.'" type="application/x-shockwave-flash" src="http://www.youtube.com/v/'.$step2[0].$auto2.'" wmode="transparent" embed="" /></embed>');
}
?>

    Problems were

    1. concatenation operator (.) was missing
    2. variable name was invalid for “$atuo1”
    3. post block was missing.

    Updates

    please replace iframe line with below one (note : one “w” was missing in URL it was “ww”)

    echo htmlentities ('<iframe src="http://www.youtube.com/embed/'.$step2[0].$auto1.'" frameborder="0" width="'.$wdth.'" height="'.$hth.'"></iframe>');
