This is my controller
function search($collg_id = '', $id = '') {
$courserecord = $this->front->get_data_wheree('tbl_course_offered');
$data['course_offrd_name'] = json_decode(json_encode($courserecord), True);

} else {
$courserecord = $this->front->get_data_wheree('tbl_course_offered');
$data['course_offrd_name'] = json_decode(json_encode($courserecord), True);
}
}
This is my model.php
function get_data_wheree($table) {
$this->db->select('course_offrd_name, collg_id');
$this->db->group_by('course_offrd_name');
return $this->db->get('tbl_course_offered')->result();
}
This is my source view page ie index.php dropdown page

</select>
</div>
</div>
</div>
</form>
<script>
$(document).ready(function () {
$("select.course").change(function () {
var selectedCourse = $(this).children("option:selected").val();
alert("You have selected the course - " + selectedCourse);
});
});
</script>
<--this is my second view page ie search.php where myselected option should display-->
<form class="form-horizontal well" action="<?php echo base_url(); ?>search" method="post" role="form">

echo "checked";
} else {

答案 0 :(得分：0)
我相信（*这里有很多代码，如果不是，请原谅我），但是我相信问题是因为您在做：
data: { course_name: 'course_name' },
何时应该做：
data: { course_name: selectedCourse },
您发送的是“ course_name”的文本/字符串，而不是您选择的下拉列表中的实际值。
