<table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <?php $i=0; foreach($info['list'] as $ent){ $ent = $ent['info']; $checked = $ent['flag']==1?"checked='checked'":""; }?> <td> <input id="view_<?php echo $i;?>" class="Sedd" type="checkbox" value="<?php echo $ent["code"];?>" name="view[]" <?php echo $checked;?>> <label for="view_<?php echo $i;?>"><?php echo $ent["name"];?></label> </td> <?php if(($i+1)%4==0){?></tr><tr><?php }?> <?php $i++; }?> </tr></table>

Copy after login

大虾：
为什么
$i++;
}?>
说这里多了一个} 我删除掉之后就报

$checked = $ent['flag']==1?"checked='checked'":""; 这一行代码错误

Copy after login

$i++;
}?>
说这里多了一个} 我删除掉之后就报

$checked = $ent['flag']==1?"checked='checked'":""; 这一行代码错误

一开始系统报多了一个括号｝说多一个｝，那么我删除掉 }.
可是接着又报$checked = $ent['flag']==1?"checked='checked'":""; 这行代码错误！

我写多了一个好像，最下面那个}号是foreach的结束。你试试下面这段：

<table width="100%" border="0" cellspacing="0" cellpadding="0"> <tr> <?php $i=0; foreach($info['list'] as $ent){ $ent = $ent['info']; $checked = $ent['flag']==1?"checked='checked'":""; ?> <td> <input id="view_<?php echo $i;?>" class="Sedd" type="checkbox" value="<?php echo $ent["code"];?>" name="view[]" <?php echo $checked;?>> <label for="view_<?php echo $i;?>"><?php echo $ent["name"];?></label> </td> <?php if(($i+1)%4==0){?></tr><tr><?php }?> <?php $i++; }?> </tr></table>

Copy after login

$checked = $ent['flag']==1?"checked='checked'":"";
说这行报错！

这段html没错的。我测试过了。检查你的info数组,是否有authflag这个key.
print_r($info);打印出来看看$info里面的数据的情况。
针对你的html，我给了一段模拟的数组：

$info=array('list'=>array( array('info'=>array('flag'=>1,'code'=>1,'name'=>1)), array('info'=>array('flag'=>0,'code'=>2,'name'=>2)), array('info'=>array('flag'=>1,'code'=>3,'name'=>3)), array('info'=>array('flag'=>0,'code'=>4,'name'=>4)), array('info'=>array('flag'=>0,'code'=>5,'name'=>5)), array('info'=>array('flag'=>0,'code'=>6,'name'=>6)), array('info'=>array('flag'=>0,'code'=>7,'name'=>7)), array('info'=>array('flag'=>0,'code'=>8,'name'=>8)), ));

Copy after login

<table width="100%" border="0" cellspacing="0" cellpadding="0">  <?php $i = 0; foreach($info['list'] as $ent){if($i % 4 == 0) echo '<tr>'; //注意这里 $ent = $ent['info']; $checked = $ent['flag']==1?"checked='checked'":""; echo '<td>'; echo '<input id="view_'.$i.'" class="Sedd" type="checkbox" value="'.$ent["code"].'" name="view[]" '.$checked.'>'; echo ' '; echo '<label for="view_'.$i.'">'.$ent["name"].'</label>'; echo ' '; echo '</td>'; $i ++;if($i % 4 == 0) echo '</tr>'; //注意这里 } ?> <?php echo $i % 4 ? '</tr>' : ''; //注意这里 ?></table>

Copy after login

有的[authflag] => 1
--------------------------------------------------
" name="view_[]" >报错

说这行也报错的

Copy after login
