[英]POST method doesn't work in Yii2 using PHP
My application is using Yii2. 我的应用程序使用Yii2。 I had insert this code into one of the page: 我已将此代码插入页面之一:
Multiple Selection: <input name="multi" type="checkbox" value="selected" /> ';
I want to know whether this checkbox
is been selected a not. 我想知道是否未选中此checkbox
。 Any idea how can i do it? 知道我该怎么办吗? I had tried this method but it doesn't work: 我已经尝试过这种方法,但是它不起作用:
if($_POST['multi'] == 'selected')
{ //do sth
}
If the checkbox has been checked, it will be sent in the POST
. 如果该复选框已被选中,它将在POST
发送。 Otherwise, it will be not. 否则,事实并非如此。 So: 所以:
if (isset($_POST['multi'])) {
//do stuff
}
You can use ArrayHelper 您可以使用ArrayHelper
$multi = \yii\helpers\ArrayHelper::getValue($_POST ,'multi' , null);
if($multi === 'selected'){
//do something
}
Try this 尝试这个
if (isset($_POST['multi']) && 'selected' == $_POST['multi']) {
//do stuff
}
