Question

我有一个表config_table，其中包含字段id，config_value。我要为config value

如下更新id ='6'

if($user->status_id=='1' && $user->reviewed!='0'){
    if($sl_flag==0 && $requestor_role->role_id==7){ 
        $status="Waiting for Review"; 
        $title="Waiting for Review";
    }elseif($sl_flag==0){ 
        $status="Waiting for dept.owner approval";
        $title="Waiting for Deptment owner approval ";
    }else{ 
        $status="Waiting for prac.owner approval";
        $title="Waiting for practice owner approval";
    }
}

我更新为

update config_table set config_value='     if($user->status_id=='1' && $user->reviewed!='0'){
if($sl_flag==0 && $requestor_role->role_id==7){ 
    $status="Waiting for Review"; 
    $title="Waiting for Review";
}elseif($sl_flag==0){ 
    $status="Waiting for dept.owner approval";
    $title="Waiting for Deptment owner approval ";
}else{ 
    $status="Waiting for prac.owner approval";
    $title="Waiting for practice owner approval";
}
}' where id='6';

我已经在腻子服务器中尝试过此操作，但是每行的}附近语法都出现错误。如何更新此

Answer 1

您正在''中使用config_value内的''。因此，它认为它到此结束，但是您只想分配一个值。此代码中有几个选项可修复它。首先：PHP是松散类型的，因此您可以将''中的config_value更新为""。

update config_table set config_value='     if($user->status_id=="1" && $user->reviewed!="0"){
 if($sl_flag==0 && $requestor_role->role_id==7)
 { $status="Waiting for Review"; 
 $title="Waiting for Review";
 } 
 elseif($sl_flag==0)
 { $status="Waiting for dept.owner approval";
 $title="Waiting for Deptment owner approval ";
 }
 else
 { $status="Waiting for prac.owner approval";
 $title="Waiting for practice owner approval";
 }
}' where id="6";

另一个选择是转义您使用''检查的值。这可以通过在\之前添加'来完成。

value = 'if($user->status_id==\'1\') { /*your code*/ }'

尝试使用类似这样的加号：

$value = <<< END
     if($user->status_id=='1' && $user->reviewed!='0'){
    if($sl_flag==0 && $requestor_role->role_id==7){ 
        $status="Waiting for Review"; 
        $title="Waiting for Review";
    }elseif($sl_flag==0){ 
        $status="Waiting for dept.owner approval";
        $title="Waiting for Deptment owner approval ";
    }else{ 
        $status="Waiting for prac.owner approval";
        $title="Waiting for practice owner approval";
    }
    }
END;

    update config_table set config_value=$value where id='6';
