To pass multiple values, you need to create multiple checkbox with the same name (as an array)
<input type="checkbox" name="check[]" class="chk_val" value="value1"/>
<input type="checkbox" name="check[]" class="chk_val" value="value2"/>
<input type="checkbox" name="check[]" class="chk_val" value="value3"/>
<input type="checkbox" name="check[]" class="chk_val" value="value4"/>
In your controller,
$values = $request->check; //the array of checked inputs.
Then you can loop through it
foreach($values as $value) {
...
}
Update
Accodring to the chat discussion you want to send 2 different fields per checkbox. In your checkboxes, put both fields like this
#foreach($courses as $course)
<input type="checkbox"
name="check[]"
class="chk_val"
value="{{ $course->id }}-{{ $course->section }}"/>
#endforeach
Pay attention to the value here. I added a delimiter - that will be useful in the controller. In controller now
public function selectedCourses(Request $request)
{
... //whatever you do for validation
//loop through selected courses
foreach( $request->check as $values ) {
$values = explode("-", $values); //split where we added the dash
$id = $values[0]; //the course ID
$section = $values[1]; // the course section
... do what you want here with that information
}
}
And voila!
