How to verify data rules in laravel
return ['accepted' => '必须为yes,on,1,true', 'active_url' => '是否是一个合法的url,基于PHP的checkdnsrr函数,因此也可以用来验证邮箱地址是否存在', 'after:date' => '验证字段必须是给定日期后的值,比如required|date|after:tomorrow,通过PHP函数strtotime来验证', 'after_or_equal:date' => '大于等于', 'alpha' => '验证字段必须全是字母', 'alpha_dash' => '验证字段可能具有字母、数字、破折号、下划线', 'alpha_num' => '验证字段必须全是字母和数字', 'array' => '数组', 'before:date' => '小于', 'before_or_equal:date' => '小于等于', 'between:min,max' => '给定大小在min,max之间,字符串,数字,数组或者文件大小都用size函数评估', 'boolean' => '必须为能转化为布尔值的参数,比如:true,false,1,0,"1","0"', 'confirmed' => '字段必须与foo_confirmation字段值一致,比如,要验证的是password,输入中必须存在匹配的password_confirmation字段', 'date' => '通过strtotime校验的有效日期', 'date_equals:date' => '等于', 'date_format:format' => 'date和date_format不应该同时使用,按指定时间格式传值', 'different:field' => '验证的字段值必须与字段field的值相同', 'digits:value' => '必须是数字,并且有确切的值', 'digits_between:min,max' => '字段长度必须在min,max之间', 'dimensions' => '验证的文件是图片并且图片比例必须符合规则,比如dimensions:min_width=100,min_height=200,可用的规则有min_width,max_width,min_height,max_height,width,height,ratio', 'distinct' => '无重复值', 'email' => '符合e-mail地址格式', 'exists:table,column' => '必须存在于指定的数据库表中', 'file' => '成功上传的文件', 'filled' => '验证的字段存在时不能为空', 'image' => '验证的文件必须是图像,jpeg,png,bmp,gif,svg', 'in:foo,bar,...' => '验证的字段必须包含在给定的值列表中', 'in_array:anotherfield' => '验证的字段必须存在于另一个字段的值中', 'integer' => '整数', 'ip' => 'ip地址', 'ipv4' => 'ipv4地址', 'ipv6' => 'ipv6地址', 'json' => 'json字符串', 'max:value' => '大于', 'mimetypes:text/plain,...' => '验证的文件必须与给定的MIME类型匹配', 'mimes:foo,bar,...' => '验证的文件必须具有列出的其中一个扩展名对应的MIME类型', 'min:value' => '小于', 'nullable' => '可为null,可以包含空值的字符串和整数', 'not_in:foo,bar...' => '不包含', 'numeric' => '必须为数字', 'present' => '验证的字段必须存在于输入数据中,但可以为空', 'regex:pattern' => '验证的字段必须与给定正则表达式匹配', 'required' => '验证的字段必须存在于输入数据中,但不可以为空', //以下情况视为空:1.该值为null,2.空字符串,3.空数组或空的可数对象,4.没有路径的上传文件 'required_if:anotherfield,value,...' => '如果指定的anotherfield等于value时,被验证的字段必须存在且不为空', 'required_unless:anotherfield,value,...' => '如果指定的anotherfield等于value时,被验证的字段不必存在', 'required_with:foo,bar,...' => '只要指定的其它字段中有任意一个字段存在,被验证的字段就必须存在且不为空', 'required_with_all:foo,bar,...' => '当指定的其它字段必须全部存在时,被验证的字段才必须存在且不为空', 'required_without_all:foo,bar,...' => '当指定的其它字段必须全部不存在时,被验证的字段必须存在且不为空', 'required_without:foo,bar,...' => '当指定的其它字段有一个字段不存在,被验证的字段就必须存在且不为空', 'same:field' => '给定字段必须与验证字段匹配', 'size:value' => '验证字段必须具有与给定值匹配的大小,对字符串,value对应字符数;对数字,对应给定的整数值;对数组,对应count值;对文件,是文件大小(kb)', 'timezone' => '验证字段是有效的时区标识符,根据PHP函数timezone_identifiers_list判断', 'unique:table,column,except,idColumn' => '验证字段必须是数据库中唯一的', 'url' => '有效的url',];
Simple example
return [ 'title.required' => 'A title is required', 'body.required' => 'A message is required', 'avatar' => [ 'required', Rule::dimensions()->maxWidth(500)->maxHeight(250)->ratio(3/2), //限制图片大小和比例 ], 'foo.*.id' =>'distinct', //不允许重复 'state' =>'exists:states', //指定表 'state1' => 'exists:states,abbreviation', //指定表和字段 'email' => 'exists:connection.staff,email', //指定查询的数据库 'email1' => [ 'required', Rule::exists('staff')->where(function ($query){ $query->where('account_id',1); }), ], 'zones' => [ 'required', Rule::in(['first-zone','second-zone']), ], 'video' => 'mimetypes:video/avi,video/mpeg,video/quicktime', 'photo' => 'mimes:jpeg,bmp,png', //验证文件扩展名,规则上也会验证文件的MIME类型,通过读取文件的内容以猜测它的MIME类型 'toppings' => [ 'required', Rule::notIn(['sprinkles','cherries']), ], //当使用regex时,必须使用数组,而不是|分隔符,特别是正则中有|时 'email2' => 'unique:users,email_address', 'email3' => 'unique:connection.users,email_address', //指定数据库 'email4' => Rule::unique('users')->where(function ($query){ $query->where('account_id',1); }), 'custom' => [ 'person.*.email' => [ 'unique' => 'each person must have a unique e-mail address', ] ],];
Special example
//验证时忽视idValidator::make($data,[ 'email' => [ 'required', Rule::unique('users')->ignore($user->id,'user_id'), ] ]);//在某些情况下,只有在该字段存在于输入数组中时,才可以对字段执行验证检查$v = Validator::make($data,[ 'email' => 'sometimes|required|email',//email只有在data数组中时才会被验证]);$z = Validator::make($data,[ 'email' => 'required|email', 'games' => 'required|numeric',]);$z->sometimes('reason','required|max:500',function ($input){ return $input->games >= 100; //当值超过100时,reson才必填});$z->sometimes(['reson','cost'],'required',function ($input){ return $input->games >= 100; });$validator = Validator::make($request->all(),[ 'photos.profile' => 'required|image',//验证数组中的某个key的值]);$validator = Validator::make($request->all(),[ 'person.*.email' => 'email|unique:users', 'person.*.first_name' => 'required_with:person.*.last_name',]);//验证指定数组输入字段中的每一个email都是唯一的$request->validate([ 'name' => ['required', new Uppercase()],]);$validator = Validator::make($this->request,[ 'title' => 'required|unique:posts|max:255', 'body' => 'required',])->validate();$validator->after(function ($validator){ if ($this->somethingElseIsInvalid()) { $validator->errors()->add('field', 'Something is wrong with this field!'); } });if ($validator->fails()){ }$errors = $validator->errors();echo $errors->first('email');//以数组形式获取指定字段的所有错误消息foreach ($errors->get('email') as $message){ }//验证表单的数组字段,获取数组元素的所欲错误消息foreach ($errors->get('attachments.*') as $message){ }//查看所有字段的错误消息foreach ($errors->all() as $message){ }// 检测一个字段是否有错误消息if ($errors->has('email')){ }
