我正在使用更新页面,其中我使用<select>
输入字段,我想从我的数据库中获取days
并使其成为输入字段的selected
值。它工作正常,但我的问题是当控制中的那些选定日期被设置为selected
时,其他日子正在重复。
例如:
<select name="day[]">
<option value=""></option>
<option>Monday</option>
<option>Tuesday</option>
<option>Wednesday</option>
<option>Thursday</option>
<option>Friday</option>
<option>Saturday</option>
<option>Sunday</option>
</select>
my_days = array('Monday','Wednesday','Friday');
因此,在此示例中,Monday
,Wednesday
,Friday
将被选中而不会重复
这是我的代码:
<?php
$day = $rows_load['day'];
$days = explode(',', $day);
$n = count($days);
$the_days = array(
'Monday' => 'Monday',
'Tuesday' => 'Tuesday',
'Wednesday' => 'Wednesday',
'Thursday' => 'Thursday',
'Friday' => 'Friday',
'Saturday' => 'Saturday',
'Sunday' => 'Sunday',
);
?>
<select data-placeholder="SELECT A DAY" multiple class="chosen-select chzn-select" tabindex="8" name="day[]" id="day" style="width:95%; " align="left" required>
<option value=""></option>
<?php
for($x = 0;$x < $n; $x ++){
echo "<option selected>".$the_days[ $days[ $x ] ] ."</option>";
}
?>
<option>Monday</option>
<option>Tuesday</option>
<option>Wednesday</option>
<option>Thursday</option>
<option>Friday</option>
<option>Saturday</option>
<option>Sunday</option>
</select>

答案 0 :(得分:0)
foreach ($the_days as $day_name) {
if (in_array($day_name, $days)) {
echo '<option selected>';
} else {
echo '<option>';
}
echo $day_name . '</option>';
}
