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

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)), ));
<table width="100%" border="0" cellspacing="0" cellpadding="0"> <!--<tr> 这个tr移动到循环中 --> <?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 ?
