Question

我有一个包含多行和多列的页面。

enter image description here

因此，当用户登录时，如果后端有任何条目，则应显示在前端。显示，如果后端表中的值为1，则如果0位于后端，则应取消选中。

                        {$i=0}
                        {foreach from=$last7days item=date}
                        <tr>

                             <td><b>&nbsp;&nbsp;{$date}</b><input type='hidden' name='date[]' value ='{$date}'></td>
                             <td><input type='checkbox' name='BREAKFAST[]' value='1' ><input type='hidden' name='BREAKFAST[]' value='0'></td>
                              <td><input type='checkbox' name= 'LUNCH[]' value='1'><input type='hidden' name= 'LUNCH[]' value='0'></td>
                             <td><input type='checkbox' name= 'EVENING[]' value='1'><input type='hidden' name= 'EVENING[]' value='0'></td>
                             <td><input type='checkbox' name= 'DINNER[]' value='1'><input type='hidden' name= 'DINNER[]' value='0'></td>
                              <td><input type='checkbox' name= 'MIDNIGHT[]' value='1'><input type='hidden' name= 'MIDNIGHT[]' value='0'></td>
                        </tr>
                        {/foreach}

对于php： -

   $show_details =   mysql_query("select id,user,date,BREAKFAST,LUNCH,EVENING,DINNER,MIDNIGHT,timeUpdate from phpgroupware_new.foodPlan
                        user='$name'");

表： -

mysql> select * from foodPlan;

Answer 1

试试这个，

<input type="checkbox" <?php
echo($breakfast == 1)? 'checked="checked"' : ''?> name="BREAKFAST[]" value="<?php echo $breakfast; ?>" >

$ breakfast是来自for循环的db的值。

Answer 2

我认为您应该删除定义不同值0的其他隐藏输入，并且只包含值为1的第一个输入。也许这可以帮助您启动，除非我误解了您的问题

if (isset($_POST['BREAKFAST'])
{
$breakfast = $_POST['BREAKFAST'];

foreach($breakfast as $item) 
if($item == 1) //that means box is checked
// what do you want to do
else
// what you want to do if box is not checked
}

你实际上并不需要使用数组作为输入，只需一个变量就可以了

复选框值将显示在同一页面中
