Retrieve data from multiple select box in Slim framework

Hello friends, welcome to findnerd. Today I am going to tell you how to fetch data in array from multiple select box in Slim framework. Follow the steps below:

Step 1: Lets begin by marking your select box field as follows:

<form action="/admin/fetchdata">
<select name="city[]" class="form-control" id="city" multiple="multiple">
  <option value="">Select City</option>
   {% for value in cities %}
   {% if value.city_name !='' %} 
   <option value="{{ value.city_name }}">{{ value.city_name }}</option>
   {% endif %} 
   {% endfor %}
  </select>
</form>

Adding the attribute 'multiple' to the select box, it will allow the user to select more than 1 options. User will need to hold ctrl or shift command in order to select multiple options. You can set the 'size' attribute of the select box to show larger size , so that more options are visible to the user. So after adding the above html code, following html page will be displayed as shown:

***Note: For selecting multiple options at a time from select box, you need to add square brackets after the name.

Step 2: Now you can add the following code to the controller in order to fetch the data:

$app->post('/admin/fetchdata', function () use ($app) {
    echo "<pre>";
    print_r($app->request->params('city'));
    echo "</pre>";
}

Select the following options as shown below:

print_r($app->request->params('city')): This will show you the following output:

Array
(
    [0] => Bangalore
    [1] => Dehradun
    [2] => Delhi
)

All done!
