将PHP变量加载到Javascript变量中

Question

I'm building a batabase driven website which uses Javascript to play videos on my website using the YouTube API, but I can't load in the data I have extracted via PHP into the Javascript player.

My table is (Example codes only):

ID | One | Two
---------------
01 | 832 | 943

Here's the PHP code I use to get the data:

<?php
$code_sql = "SELECT * FROM codes WHERE id = '$url_id'";
$code_res = mysqli_query($con, $code_sql);
while($code = mysqli_fetch_assoc($code_res)){

    $code_1 = $code["one"];
    $code_2 = $code["two"];

};
?> 

And Here's the Javascript I'm trying to load it into:

var $vid1 = <?php echo json_encode("$code_1"); ?>;
var $vid2 = <?php echo json_encode("$code_2"); ?>;
var videoIDs = [
    '$vid1',
    '$vid2'
];

When I load the page it gives me a Invalid Paramiters in the video player. Any ideas where I'm going wrong?

Answer 1

Remove quotes from json_encode. Also remove single quote inside array

var $vid1 = <?php echo json_encode($code_1); ?>;
var $vid2 = <?php echo json_encode($code_2); ?>;
var videoIDs = [
    $vid1,
    $vid2
];
