>im 尝试从 http://davidwalsh.name/php-calendar-controls 设置日历。 他提供了一些很棒的代码，在纸面上它似乎非常适合我的需要。 但是我对我的PHP有点生疏，并且我遇到了一些错误。 这是一篇古老的博客文章，所以我想我可能会在这里得到更快的回应。 这是代码：
<?php
/* draws a calendar */
function draw_calendar($month,$year){
/* draw table */
$calendar = '<table cellpadding="0" cellspacing="0" class="calendar">';
/* table headings */
$headings = array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
$calendar.= '<tr class="calendar-row"><td class="calendar-day-head">'.implode('</td><td class="calendar-day-head">',$headings).'</td></tr>';
/* days and weeks vars now ... */
$running_day = date('w',mktime(0,0,0,$month,1,$year));
$days_in_month = date('t',mktime(0,0,0,$month,1,$year));
$days_in_this_week = 1;
$day_counter = 0;
$dates_array = array();
/* row for week one */
$calendar.= '<tr class="calendar-row">';
/* print "blank" days until the first of the current week */
for($x = 0; $x < $running_day; $x++):
$calendar.= '<td class="calendar-day-np"> </td>';
$days_in_this_week++;
endfor;
/* keep going with days.... */
for($list_day = 1; $list_day <= $days_in_month; $list_day++):
$calendar.= '<td class="calendar-day">';
/* add in the day number */
$calendar.= '<div class="day-number">'.$list_day.'</div>';
/** QUERY THE DATABASE FOR AN ENTRY FOR THIS DAY !! IF MATCHES FOUND, PRINT THEM !! **/
$calendar.= str_repeat('<p> </p>',2);
$calendar.= '</td>';
if($running_day == 6):
$calendar.= '</tr>';
if(($day_counter+1) != $days_in_month):
$calendar.= '<tr class="calendar-row">';
endif;
$running_day = -1;
$days_in_this_week = 0;
endif;
$days_in_this_week++; $running_day++; $day_counter++;
endfor;
/* finish the rest of the days in the week */
if($days_in_this_week < 8):
for($x = 1; $x <= (8 - $days_in_this_week); $x++):
$calendar.= '<td class="calendar-day-np"> </td>';
endfor;
endif;
/* final row */
$calendar.= '</tr>';
/* end the table */
$calendar.= '</table>';
/* all done, return result */
return $calendar;
}
/* date settings */
$month = (int) ($_GET['month'] ? $_GET['month'] : date('m'));
$year = (int) ($_GET['year'] ? $_GET['year'] : date('Y'));
/* select month control */
$select_month_control = '<select name="month" id="month">';
for($x = 1; $x <= 12; $x++) {
$select_month_control.= '<option value="'.$x.'"'.($x != $month ? '' : ' selected="selected"').'>'.date('F',mktime(0,0,0,$x,1,$year)).'</option>';
}
$select_month_control.= '</select>';
/* select year control */
$year_range = 7;
$select_year_control = '<select name="year" id="year">';
for($x = ($year-floor($year_range/2)); $x <= ($year+floor($year_range/2)); $x++) {
$select_year_control.= '<option value="'.$x.'"'.($x != $year ? '' : ' selected="selected"').'>'.$x.'</option>';
}
$select_year_control.= '</select>';
/* "next month" control */
$next_month_link = '<a href="?month='.($month != 12 ? $month + 1 : 1).'&year='.($month != 12 ? $year : $year + 1).'" class="control">Next Month >></a>';
/* "previous month" control */
$previous_month_link = '<a href="?month='.($month != 1 ? $month - 1 : 12).'&year='. ($month != 1 ? $year : $year - 1).'" class="control"><< Previous Month</a>';
/* bringing the controls together */
$controls = '<form method="get">'.$select_month_control.$select_year_control.' <input type="submit" name="submit" value="Go" /> '.$previous_month_link.' '.$next_month_link.' </form>';
?>
首次加载日历时出现错误：注意：未定义的索引：C：\wamp\www\david walsh 日历中的月份\draw_calendar.php在第 70 行和年份在第 71 行。
我尝试做这样的事情：
if(!isset($month)){
$month = date(‘n’);
} else{
$month = (int) ($_GET['month'] ? $_GET['month'] : date(‘m’));
}
但这不起作用，它加载正确，但随后日历按钮停止工作以转到下个月或上个月。 无论如何，是否可以使日历加载当前月份和年份，并且仍然允许下个月和上个月按钮工作？
提前感谢任何可以阐明的人！
将第
70 行和第 71 行更改为：
/* date settings */
$month = (int) (isset($_GET['month']) ? $_GET['month'] : date('m'));
$year = (int) (isset($_GET['year']) ? $_GET['year'] : date('Y'));
并在文件末尾添加：
echo $controls;
echo draw_calendar($month,$year);
将此添加到代码末尾：
echo $controls; echo draw_calendar($month,$year);
<?php
echo $mth[$mo]." ".$yr;
?>
