【问题描述】：

几个月前，我解决了从两个表中获取数据并制作事件日历的问题。你可以在这里看到：original question。 现在我想要更多：我想同时为每个用户宣传一个活动。假设是一个假期（比如圣诞节），我想为所有用户添加这个事件。我使用两个查询，首先是选择假期，其次是选择用户是否在场。如果存在tip_id = 0，如果不是tip_id = 1。比我把所有东西都放在一个表中。如果当天是星期六或星期日，则颜色为灰色（使用 css1），如果用户在场，则单元格颜色为白色，如果用户不在，则颜色为红色。 我需要的？如果我在那个月有假期，我需要单元格颜色也为灰色（如周六和周日）。我尝试了不同的想法，但或者我只能在第一个假期变灰，或者只有最后一天变灰，或者当那个月没有假期时我得到了错误。 代码（只提取我需要帮助的部分）是这样的：

$db_luna=11;
$db_an=2013;
$days_in_month = 31;

mysql_select_db($database_dbconfig, $dbconfig);
$query_Holidays = "SELECT substring(data,9,2) AS zile_sarbatoare, data FROM sarbatori WHERE sarbatori.`data` LIKE '".$db_an."-".$db_luna."-%' ORDER BY zile_sarbatoare";
$Holidays = mysql_query($query_Holidays, $dbconfig) or die(mysql_error());
$row_Holidays = mysql_fetch_assoc($Holidays);
$totalRows_Holidays = mysql_num_rows($Holidays);

mysql_select_db($database_dbconfig, $dbconfig);
$query_Presence = "SELECT c.full_name, c.id_personal, COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-01') BETWEEN start_date AND end_date THEN tip_id END),0) '1', COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-02') BETWEEN start_date AND end_date THEN tip_id END),0) '2', COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-03') BETWEEN start_date AND end_date THEN tip_id END),0) '3', COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-04') BETWEEN start_date AND end_date THEN tip_id END),0) '4', COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-05') BETWEEN start_date AND end_date THEN tip_id END),0) '5' FROM calendar c";
$Presence = mysql_query($query_Presence, $dbconfig) or die(mysql_error());
$row_Presence = mysql_fetch_assoc($Presence);
$totalRows_Presence = mysql_num_rows($Presence);



<?php do  ?>
        <tr>
            <td><?php echo $nr_crt, '. ' , $row_Presence['full_name']; ?></td>
                <?php           
                $css1 = 'white';
                $trim = ''; 
                    for ($a = 1; $a <= $days_in_month; $a++)
                        $data_calculata = date("Y-m-d",mktime(0,0,0, $db_luna, $b, $db_an ));
                            if ($row_Presence[$a] == 0) $legend = $row_Presence['full_name']."".$a;
                                                         $day_of_week = date("N",mktime(0,0,0, $db_luna,$a ,$db_an));
                                                         if ($day_of_week == 6 OR $day_of_week == 7) $css1 = 'grey';
                                                         else $css1 = 'white';
                            if ($row_Presence[$a] == 1) $css1 = 'red'; $legend = $row_Presence['full_name']." - Absent";
                        echo '<td " title= "'.htmlspecialchars($legend).'" class='.$css1.'></td>';
                        $nr_crt = $nr_crt + 1;
                ?>          
        </tr>            
    <?php  while ($row_Presence = mysql_fetch_assoc($Presence)); ?>
  </table>

【问题讨论】：

最好在事件表中指定一个类型并将其设置为“全部”，而不是为每个用户输入一个条目。选择时，您可以通过 WHERE type = 'ALL' OR user_id = 10 之类的条件来获取它。这只是一个建议，请根据您的要求进行验证

【参考方案1】：

我找到的解决方法是这样的：

$db_luna=11;
$db_an=2013;
$days_in_month = 31;

mysql_select_db($database_dbconfig, $dbconfig);
$query_Holidays = "SELECT substring(data,9,2) AS zile_sarbatoare, data FROM sarbatori WHERE sarbatori.`data` LIKE '".$db_an."-".$db_luna."-%' ORDER BY zile_sarbatoare";
$Holidays = mysql_query($query_Holidays, $dbconfig) or die(mysql_error());
$totalRows_Holidays = mysql_num_rows($Holidays);
$days_holidays = array();
while ($row_Holidays = mysql_fetch_array($Holidays))
 
     $days_holidays[] = $row_Holidays['zile_sarbatoare'];
 
// so, now I have an array with all the days I need

mysql_select_db($database_dbconfig, $dbconfig);
$query_Presence = "SELECT c.full_name, c.id_personal, COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-01') BETWEEN start_date AND end_date THEN tip_id END),0) '1', COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-02') BETWEEN start_date AND end_date THEN tip_id END),0) '2', COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-03') BETWEEN start_date AND end_date THEN tip_id END),0) '3', COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-04') BETWEEN start_date AND end_date THEN tip_id END),0) '4', COALESCE(MIN(CASE WHEN CONCAT($db_an, '-', $db_luna, '-05') BETWEEN start_date AND end_date THEN tip_id END),0) '5' FROM calendar c";
$Presence = mysql_query($query_Presence, $dbconfig) or die(mysql_error());
$row_Presence = mysql_fetch_assoc($Presence);
$totalRows_Presence = mysql_num_rows($Presence);



<?php do  ?>
    <tr>
        <td><?php echo $nr_crt, '. ' , $row_Presence['full_name']; ?></td>
            <?php           
            $css1 = 'white';
            $trim = ''; 
                for ($a = 1; $a <= $days_in_month; $a++)
                    $data_calculata = date("Y-m-d",mktime(0,0,0, $db_luna, $b, $db_an ));
                     if ($row_Presence[$a] == 0) $legend = $row_Presence['full_name']."".$a;
                                                     $day_of_week = date("N",mktime(0,0,0, $db_luna,$a ,$db_an));
                           $css1 = 'white';                                                         
                        if ($day_of_week == 6 OR $day_of_week == 7) $css1 = 'grey';
                        if (in_array($a, $days_holidays)) $css1 = 'grey'; //here I compare each day if it is in the array
                     if ($row_Presence[$a] == 1) $css1 = 'red'; $legend = $row_Presence['full_name']." - Absent";
                    echo '<td " title= "'.htmlspecialchars($legend).'" class='.$css1.'></td>';
                    $nr_crt = $nr_crt + 1;
            ?>          
    </tr>            
<?php  while ($row_Presence = mysql_fetch_assoc($Presence)); ?>

对我来说它正在工作！使用函数“in_array”的想法来自该站点的另一个问题。谢谢*** :)
