I'm new to programming, and I'm trying to call a function when the user inputs data and clicks submit button. I'm using Yii2 and I'm not familiar with Ajax. I tried developing a function, but my controller action isn't called.
Here is the example code I'm trying:
views/index.php:
<script>
function myFunction()
{
$.ajax({
url: '<?php echo Yii::$app->request->baseUrl. '/supermarkets/sample' ?>',
type: 'post',
data: {searchname: $("#searchname").val() , searchby:$("#searchby").val()},
success: function (data) {
alert(data);
}
});
}
</script>
<?php
use yii\helpers\Html;
use yii\widgets\LinkPager;
?>
<h1>Supermarkets</h1>
<ul>
<select id="searchby">
<option value="" disabled="disabled" selected="selected">Search by</option>
<option value="Name">Name</option>
<option value="Location">Location</option>
</select>
<input type="text" value ="" name="searchname", id="searchname">
<button onclick="myFunction()">Search</button>
<h3> </h3>
Controller:
public function actionSample(){
echo "ok";
}
My problem is that when I click on the Search button nothing happens, and when I try to debug it, the debugger runs no code!
This is sample you can modify according your need
public function actionSample()
{
if (Yii::$app->request->isAjax) {
$data = Yii::$app->request->post();
$searchname= explode(":", $data['searchname']);
$searchby= explode(":", $data['searchby']);
$searchname= $searchname[0];
$searchby= $searchby[0];
$search = // your logic;
\Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
return [
'search' => $search,
'code' => 100,
];
}
}
If this will success you will get data in Ajax success block. See browser console.
$.ajax({
url: '<?php echo Yii::$app->request->baseUrl. '/supermarkets/sample' ?>',
type: 'post',
data: {
searchname: $("#searchname").val() ,
searchby:$("#searchby").val() ,
_csrf : '<?=Yii::$app->request->getCsrfToken()?>'
},
success: function (data) {
console.log(data.search);
}
});
you have to pass _csrf tokin as a parameter
_csrf: yii.getCsrfToken()
or you can disable csrf valdation
