我在视图中有这个表单:
<form method="POST" action="<?php echo Yii::$app->request->baseUrl;?>/telephone/addnow/" role="form" enctype="multipart/form-data">
<label>Upload your photo:</label><input type="file" name="image" ><br>
<input type="name" name="name" id="name" placeholder="Name" required><br><br>
<input type="text" name="address" placeholder="Address"><br><br>
<input type="text" name="telephone" placeholder="Telephone number" required>
<br><br>
<div id="dynamicInput">
<br><input type="text" name="myinputs[]" placeholder="Secondary Phone #1">
<span class="glyphicon glyphicon-plus" onClick="addInput('dynamicInput');"></span>
<br><br>
</div>
<input type="text" name="mobile" placeholder="Mobile number" > <br><br>
<input type="email" name="email" placeholder="Email">
<input type="email" name="altemail" placeholder="Alternative Email"><br><BR>
<input type="text" name="company_name" placeholder="Company Name"><br><BR>
<input type="text" name="company_address" placeholder="Company Address"><br><br>
<input type="text" name="company_phone_primary" placeholder="Company Telephone">
<input type="text" name="company_phone_secondary" placeholder="Telephone Secondary "><br><br>
<input type="text" name="company_email" placeholder="Company Email Address"><br><BR>
<button type="submit" class="btn btn-default">Submit</button><BR><BR>
</form>
允许用户插入我使用此javascript代码的任意数量的辅助电话:
<script>
var counter = 1;
var limit = 10;
function addInput(divName) {
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
} else {
var newdiv = document.createElement('div');
newdiv.innerHTML = "Seconday Phone # " + (counter + 1) + " <br><input type='text' name='myinputs[]' placeholder='Secondary Phone '>";
document.getElementById(divName).appendChild(newdiv);
counter++;
}
}
</script>
我有这个控制器代码:
public function actionAddnow()
{
$request = Yii::$app->request;
$add=new telephone();
$add->Name=$request->post('name');
$add->Email=$request->post('email');
$add->Mobile=$request->post('mobile');
$add->Address=$request->post('address');
$add->Telephone=$request->post('telephone');
$add->altemail=$request->post('altemail');
$add->company_name=$request->post('company_name');
$add->company_address=$request->post('company_address');
$add->company_phone_primary=$request->post('company_phone_primary');
$add->company_phone_secondary=$request->post('company_phone_secondary');
$add->company_email=$request->post('company_email');
$add->save();
$getlast=Yii::$app->db->getLastInsertId();
$myinputs=$request->post('myinputs');
$totalinputs=sizeof('$myinputs');
for ($i=0; $i<=$totalinputs; $i++) {
$inputs=$myinputs[$i];
$phones=new phone();
$phones->secondary_phones=$inputs;
$phones->id=$getlast;
$phones->save();
}
return $this->redirect(Yii::$app->request->baseUrl.'/telephone/index');
}
但只有$myinputs
的前两个值插入数据库中。
答案 0 :(得分:1)
将变量$ myinputs放在单引号(&#39; $ myinputs&#39;)之间,您将变量转换为字符串。 this article是count函数的别名,但是当你将参数作为字符串给出时,你总是得到结果为1.你将循环使用条件($ i = 0; $ i&lt; = $ totalinputs; $ i ++)意味着这个循环当$ i为0且$ i为1时,将运行2次。
而不是:
$totalinputs=sizeof('$myinputs');
您应该使用
$totalinputs=sizeof($myinputs);
另一个错误是你的周期状况。
for ($i=0; $i<=$totalinputs; $i++)
应
for ($i=0; $i<$totalinputs; $i++)
或者你可以用foreach替换循环
foreach($myinputs as $inputs)
{
$phones=new phone();
$phones->secondary_phones=$inputs;
$phones->id=$getlast;
$phones->save();
}
改善方面
1.对于表单,您可以使用sizeof小部件
$form = \yii\widgets\ActiveForm::begin([
'options' => [
"role" => "form",
"enctype"=> "multipart/form-data",
], ]);
echo $form->field($add, 'Name');
//etc
$form->end();
2.如果您使用ActiveField在视图中创建输入字段或以ModelClassName [ModelFieldName]等格式手动添加字段名称,那么您将能够使用模型加载来分配值 例如:
$add=new telephone();
if ($add->load(Yii::$app->request->post()))
{
if ($add->save())
{//saved
}
else
{//error
}
}
else
{//no post data
}
3.对于url,可能不需要添加请求baseUrl属性。 ActiveForm中的示例您只需使用
即可$this->redirect('/telephone/index');
4.当数据库中存在一些将创建其他行的触发器时,使用方法getLastInsertId()可能会导致错误。所以使用它可能更明智:
$getlast=$add->id;//assuming model autoincrement field name is "id"
