($y) 之间的来自数据库（$ending[0] && $starting[0], $ending[1] && $starting[1]等）的多个数组值。 ＆＃34; 如果＆＃34; $y介于其中echo "statement"之间。{/ 1}
我使用for循环以 30分钟间隔从上午9点 - 晚上7点递增下拉。
如果这些时间中的任何一个=我的数据库中保存的时间，它回应＆＃34; 不可用＆＃34;代替。
现在我需要看到＆＃34; 如果＆＃34;下拉时间为＆＃34; ＆＃34;数据库中的开始和结束时间，并使那些＆＃34;不可用＆＃34;同样。
如果我手动识别要比较的数组键，那么一切正常......但我的问题是：我可以针对数组中的所有值检查下拉值吗？
实施例： 开始下拉：09：00 am 09:30 am上午10:00等，直至07:30。结束下拉：上午09:30上午10:00上午10:30等，直到晚上08:00。如果上午9:00（开始）上午10:00（结束）的开始和结束时间保存在数据库中进行预约，则下拉列表将显示＆＃34;不可用＆＃34;对于相应的开始和结束时间，因此用户不能双重预约。我要问的是，如何识别＆＃34;之间的所有＆＃34;价值...例如09:30 am，如果已经预订了09:00 am-10：00am的话，则不能是开始时间或结束时间。

那怎么样？
$sql_slots = "SELECT * FROM XXXXX WHERE date = '$query_date' ORDER BY XXXXX ASC";
$result_slots = mysqli_query($connection, $sql_slots);
$open = strtotime("9:00am");
$close = strtotime("9:30am");
$reserved = array();
while($row_result_slots = mysqli_fetch_assoc($result_slots)){
$start = $row_result_slots['start_time'];
while ($start <= $row_result_slots['end_time']) {
$reserved[$start] = true;
$start = date("Y/m/d h:i:s", strtotime($start . "+30 minutes"));
}
}
echo '<select name="start_time">';
for($b = 0; $b <= 20; $b++){
$y = strtotime(($b*30) . " Minutes", $open);
$the_time = date("h:ia", $y);
if(isset($reserved[$the_time]){
echo "<option>Not Available<br></option>";
} else {
echo "<option>" . $the_time . "<br></option>";
}
}
echo'</select>';

以下是我的想法。这使用do while循环并创建一个reserved数组，该数组将填充约会中给出的所有时间。
我更新了数据以使用我自己的数组，但更新了mysqli工作的正确性。如果没有，我留在我的测试代码中供您查看是否需要。我还使用disabled attribute上的option <?php
$sql_slots = "SELECT * FROM XXXXX WHERE date = '$query_date' ORDER BY XXXXX ASC";
$result_slots = mysqli_query($connection, $sql_slots);
$open = strtotime("9:00am");
$close = strtotime("7:00pm");
$space = 900; //15min * 60 seconds space between?
//This seems more normal for people to see.
//Simulate these appoinments
/*
$query_results = array(
array(
"start_time" => "9:00am",
"end_time" => "9:30am"
),
array(
"start_time" => "10:30am",
"end_time" => "11:30am"
),
array(
"start_time" => "11:45am",
"end_time" => "12:30pm"
)
);
*/
$reserved = array();
while($row_result_slots = mysqli_fetch_assoc($result_slots)){
//**NOTE**: Make sure these are times or use strtotime()
$next_slot = $reserved[] = strtotime($row_result_slots['start_time']);
$end_time = strtotime($row_result_slots['end_time']);
while($next_slot < $end_time){
$next_slot += $space;
$reserved[] = $next_slot;
}
}
/*
foreach($query_results as $appoinment) {
$next_slot = $reserved[] = strtotime($appoinment['start_time']);
$end_time = strtotime($appoinment['end_time']);
while($next_slot < $end_time){
$next_slot += $space;
$reserved[] = $next_slot;
}
}
*/
echo'<select name="start_time">';
$current = $open;
do {
$disabled = in_array($current, $reserved) ? 'disabled' : '';
echo '<option ' . $disabled . '>' . date("h:ia", $current) . '</option>';
$current += $space;
} while($current <= $close);
echo'</select>';
输出了一些文字。
app.get('/profile', function(req, res){
var msg = req.flash('message');
var username1 = req.user.username;
Products.find({'username': username1}).sort('-date').exec(function(err, docs){
res.render('profile', { title: 'Products', products: docs, flashmsg: msg});
});
});
