php中的while循環和數組
[英]While loop and array in php
問題描述
我有一個 while 循環，它將循環 2 次（星期一和星期二）。 在while循環中，我有一個條件來檢查第一個循環是否是“星期一”，如果是星期一，它將檢查該值並檢查相應的復選框。
該代碼在星期一完美運行。 但是星期二的復選框根本沒有回聲。

當您檢查變量$rowTime ，您的while循環會更改變量$rowDay 。 您可能需要仔細檢查一下。

使用此代碼：
<div class="form-group">
<table>
<tr>
<td style="width: 10%"> </td>
<?php
//Get the list of time
$sqlTime="SELECT timeDesc FROM time";
$resultTime=mysql_query($sqlTime);
while($rowTime=mysql_fetch_array($resultTime))
{
?>
<td style="text-align: center"><?php echo $rowTime['timeDesc'];?></td>
<?php
}
?>
</tr>
<?php
//Get the list of day
$sqlDay="SELECT dayDesc FROM day";
$resultDay=mysql_query($sqlDay);
while($rowDay=mysql_fetch_array($resultDay))
{
?>
<tr>
<td><?php echo $rowDay['dayDesc'];?></td>
<?php
//Get the list of time
$sqlTime="SELECT * FROM time";
$resultTime=mysql_query($sqlTime);
$preferences = array('Monday' => 'tutorPreferencesMon',
'Tuesday' => 'tutorPreferencesTues',
'Wednesday' => 'tutorPreferencesWed',
'Thursday' => 'tutorPreferencesThurs',
'Friday' => 'tutorPreferencesFri',
'Saturday' => 'tutorPreferencesSat',
'Sunday' => 'tutorPreferencesSun');
while($rowTime=mysql_fetch_array($resultTime))
{
$preferences = $preferences[$rowDay['dayDesc']];
$sqlGetMonday = mysql_query("SELECT ".$preferences." FROM tutorpreferences WHERE tutorID='$showTutorID'");
$resultGetMonday = mysql_fetch_array($sqlGetMonday);
$tutorGetMonday = $resultGetMonday[$preferences];
$showMonday = $tutorGetMonday;
$mondayArray = explode(',', $showMonday);
while($rowTimeList=mysql_fetch_array($resultTimeList))
{
$checkedMonday = "";
foreach($mondayArray as $monday_Array)
