Can not update data with ajax on codeigniter - php

Question

I tried to update the data with ajax on php but it went wrong while ajax information has been successful but the data is not updated, I think the script is correct but do not want to update the data, what is wrong with my script ??
<input type="hidden" id="select_id" name="select_id" value="<?php echo $read_inbox['id_data']; ?>" />
$('[id^=delete_read_inbox]').click(function() {
if (confirm('You are sure to delete this message?')) {
var id = $("#select_id").val();
var url = base_url+'message/delete_inbox_read';
$.ajax({
url : url,
type: 'POST',
data: 'select_id='+id,
success: function(response) {
console.log('success');
},
error: function (request, jqXHR, textStatus, errorThrown) {
console.log(request.responseText);
}
});
} else {
}
});
Controllers
function delete_inbox_read() {
$this->Message->delete_ReadInbox();
redirect('user/message/inbox');
}
Models
function delete_ReadInbox() {
$update = $this->input->post('select_id');
$data = array(
'delete_pa_inbox' => 0
);
$this->db->where('id_Message', $update);
$this->db->update('tb_message', $data);
}

Answer 1

you are trying to POST 'id' from js and fetching 'select_id' on PHP side, hence its not working, change to:
...
var id = $("#select_id").val();
var url = base_url+'message/delete_inbox_read';
$.ajax({
url : url,
type: 'POST',
data: { 'id' : id },
success: function(response) {
console.log('success');
},
....
Controller:
function delete_inbox_read() {
//get the POST data
$select_id = $this->input->post('id'); //id not select_id
$this->Message->delete_ReadInbox($select_id);
//redirect('user/message/inbox'); //remove redirect
echo "done";
}
Model:
function delete_ReadInbox($select_id) {
$data = array(
'delete_pa_inbox' => 0
);
$this->db->where('id_Message', $select_id);
$this->db->update('tb_message', $data);
}
