Question

我创建了一个下拉列表，其中我在15分钟的间隙中显示所有时间。

我想禁用当前服务器时间之前的所有时隙。

<?php
// print date('H:i');
//$var="abc";
//$var = date('H:i');
 $time = date('G:i');
 echo $time;
    $start = "00:00"; 
    $end = "23:45";

    $tStart = strtotime($start);
    $tEnd = strtotime($end);
    $tNow = $tStart;
    echo '<select name="schedule_time">';
    //if($tt >= 12 && $tt <= 14){$dis = ' disabled';}else{$dis = ''}echo '<option value="wr"'.$dis.'>Washington Redskins</option>';
    while($tNow <= $tEnd)
    {
        //if($time < $start){$tNow = 'disabled';}else{$tNow = '';} echo '<option value="'.date("H:i",$tNow).'">'.date("H:i",$tNow).'</option>';
        echo '<option value="'.date("H:i",$tNow).'" disabled>'.date("H:i",$tNow).'</option>';
        $tNow = strtotime('+15 minutes',$tNow);
    }
    echo '</select>';

Answer 1

您应该将时间与服务器时间进行比较，如果较小则禁用该选项。它看起来像这样：

<?php
     $time = date('G:i');
     $start = "00:00"; 
     $end = "23:45";

     $serverTime = strtotime($time);
     $tStart = strtotime($start);
     $tEnd = strtotime($end);
     $tNow = $tStart;
     echo '<select name="schedule_time">';
     while($tNow <= $tEnd)
     {
        if($tNow < $serverTime) { $disable = 'disabled'; } else { $disable = ''; }
        echo '<option value="'.date("H:i",$tNow).' " '.$disable.'>'.date("H:i",$tNow).'</option>';
        $tNow = strtotime('+15 minutes',$tNow);
     }
     echo '</select>';

?>

我认为您只需要显示future时间下拉列表

循环value $tNow为smaller而不是current time strtotime(date('G:i'))意味着你需要disable这样。

<?php

 $time = date('G:i');
 echo $time;
    $start = "00:00"; 
    $end = "23:45";
    $tStart = strtotime($start);
    $tEnd = strtotime($end);
    $tNow = $tStart;
    echo '<select name="schedule_time">';
    while($tNow <= $tEnd)
    {

        if($tNow <= strtotime(date('G:i'))){ $prop ='disabled';  }else{ $prop='';  }
        echo '<option value="'.date("H:i",$tNow).'" '.$prop.'>'.date("H:i",$tNow).'</option>';
        $tNow = strtotime('+15 minutes',$tNow);
    }
    echo '</select>';

?>
