<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>

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

$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>
$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)), ));
<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 ? '</tr>' : ''; //注意这里 ?></table>

有的[authflag] => 1

" name="view_[]" >报错
说这行也报错的

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
