The yii framework form model submits form data in the form of an array

According to the description in the Yii documentation, the general process of Yii processing forms is: Create a model class corresponding to the form and set field validation rules Create an action corresponding to form submission and process the submitted content Create a form in the view In a small project just now, I wanted to use ajax to submit form information and verify and save it, but I didn’t want to use a hidden iframe for non-refresh submission, and the verification method of the model class could be used in the action, so I thought of using the form array submission method. . Example, form code:

<form action='' method='post' name='form_test'>
 <input type='text' name='arr[]' value='1'>
 &lt ;input type='text' name='arr[]' value='2'>
 <input type='text' name='arr[]' value='3'>
</form>

After submission, you can directly use $_POST['arr'] to get the submitted data. $_POST['arr'] is: Array ( [0] => a [1] => b [2] => c )

Similarly, if you use the following form to submit:

<form action='' method='post' name='form_test'>
 <input type='text' name='arr[3]' value='a'>
 <input type='text' name='arr[6]' value='b'>
 <input type='text' name='arr[8]' value='c'>
< /form>

$_POST['arr'] as: Array ( [3] => a [6] => b [8] => c )

Of course you can also submit a two-dimensional array:

<form action='http://127.0.0.1/zhaobolu/test.php' method='post' name='form_test'>
 <input type='text' name=' arr[][name1]' value='a'>
 <input type='text' name='arr[][name2]' value='b'>
 <input type='text' name ='arr[][name3]' value='c'>
</form>

$_POST['arr'] is: Array ( [0] => Array ( [name1] => a ) [1] => Array ( [name2] => b ) [2] => Array ( [name3] => c ) ) There is a problem here. If you do not set the key of the first sub-array, each value will be added to arr sequentially when generating the array. If you want to save the information in an array, just add a key value, as follows:

<form action='http://127.0.0.1/zhaobolu/test.php' method='post' name='form_test'>
 <input type='text' name=' arr[a][name1]' value='a1'>
 <input type='text' name='arr[a][value1]' value='a2'>
 <input type='text ' name='arr[b][name2]' value='b1'>
 <input type='text' name='arr[b][value2]' value='b2'>
</ form>

$_POST['arr'] is: Array ( [a] => Array ( [name1] => a1 [value1] => a2 ) => Array ( [name2] => b1 [value2] => b2 ) )

An example of using ajax to submit a form and verifying it using the yii form model. The first is the model class part, which has only the simplest verification method:

<?php
class LandingForm extends CFormModel
{
 public $landing_title;
 public $landing_content;
 public $landing_position;
 public function rules()
 {
 return array(
 array('landing_title, landing_content', 'required'),
 array('landing_position', 'default', 'value'=>''),
 );
 }
}

The model class is setting parameters When verifying the method, you need to set rules for each public parameter. If there are parameters without set rules, after assigning values ​​to the model using the form value in $_POST, the parameter values ​​without set rules will be empty. Get the parameters submitted by the form in the action and verify:

$model = new LandingForm;
$model->attributes = $_POST['form'];
if($model->validate()){
 $info = $model-> attributes;
 ...
}

The last is the code for the front-end submission form part, using jquery:

var info = new Object();
info = { 'form[landing_title]': landing_title,
 'form[landing_content]': landing_content,
 'form[landing_position]': landing_position,
 };
var url = "...";
$.post(url, info, function(rst){
 ...
});
