Javascript Php mysql用户评级系统对不同餐厅的评级存在问题

我的用户评级系统有问题。一旦我给一家餐馆打分，然后去了另一家餐馆，我就不能给那家餐馆打分了，它会被禁用

我在index.php

echo starBar（510316）中注意到了这一点中间的一个103是mediaId当我更改此id号并去投票时，出现问题，然后它就工作了，一旦我再次使用此媒体id评分，任何地方都无法评分

完整代码如下：

index.php

<?php
$getRest    = $_GET['sid'];

function starBar($numStar, $mediaId, $starWidth) { // function with arguments: number of stars, media ID, width of the star image
    global $bdd;
    $cookie_name = 'tcRatingSystem'.$mediaId; // Set up the cookie name
    $sid    = mysql_real_escape_string($_GET['sid']);
    // We get the rate average and number of rate from the database
    $query = $bdd->getOne('SELECT round(avg(rate), 2) AS average, count(rate) AS nbrRate, sr_id AS sr_id FROM rest_rating WHERE media='.$mediaId.' and sr_id = "'.$sid.'"');
    $avgCeil = round($query['average'], 0); // round above or below to show how many selected stars we display

    $getJSON = array('numStar' => $numStar, 'mediaId' => $mediaId); // We create a JSON with the number of stars and the media ID
    $getJSON = json_encode($getJSON);

    // We create the DIV block with selected stars and unselected stars depending of the rate
    $starBar = '<div id="'.$mediaId.'">';
    $starBar .= '<div class="';
    if( !isset($_COOKIE[$cookie_name]) ) $starBar .= 'star_bar';
    $starBar .= '" rel='.$getJSON.' style="width:'.($numStar*$starWidth).'px">';

    for ($i=1; $i<=$numStar; $i++) {
        $starBar .= '<div class="';
        if ($i <= $avgCeil) $starBar .= 'star_selected'; else $starBar .= 'star';
        $starBar .= '"></div>';
    }
    $starBar .= '</div>';
    $starBar .= '<div class="resultMedia'.$mediaId.'" style="font-size: small; color: grey">'; // We show the rate score and number of rates
    if ($query['nbrRate'] == 0) $starBar .= 'Not rated yet';
    else $starBar .= 'Rating: ' . $query['average'] . '/' . $numStar . ' (' . $query['nbrRate'] . ' votes)';
    $starBar .= '</div>';
    $starBar .= '<div class="box'.$mediaId.'"></div>'; // Return the text "Thank you for rating" when someone rate
    $starBar .= '</div>';

    return $starBar;
}

echo starBar(5, 103, 16); // We create star bar     
?>
