CodeIgniter: Delete data from MySQL DB using AJAX - php

Question

I am working on a project, where inside admin panel I have a table for enquiries and I want to allow admin to delete any of them.
My view code is as follows:
<button type="button" class="btn btn-danger delbtn" onclick="delenquiry(<?php echo $value->id;?>)">Delete this Enquiry</button>
My ajax code is:
function delenquiry(id) {
if (confirm("Are you sure?")) {
$.ajax({
url: base_url + 'loginc/delenq',
type: 'post',
data: id,
success: function () {
alert('ajax success');
},
error: function () {
alert('ajax failure');
}
});
} else {
alert(id + " not deleted");
}
}
Controller code is:
public function delenq() {
$id = $this->input->post('id');
$this->logins->delenqs($id);
}
And model code is:
public function delenqs($id) {
$this->db->where('id', $id);
$this->db->delete('enquiry');
}
I looked for answers, but didn't got any. Can anyone tell me what's wrong with my code. Thanks in advance...

Answer 1

You need to pass id from your ajax request change
data: id,
To
data: {id:id},
for data you must provide an array .
for example => data:{name_params:10}
you can get data in php $id = $this->input->post('name_params');
and the value $id will be = 10

Answer 2

The issue you have is that your ID is not an available key in your POST. You would need to define {id : id}. However, I think this makes more sense from an MVC approach:
$.ajax({
url: base_url + 'loginc/delenq/'+ id, //maintains the (controller/function/argument) logic in the MVC pattern
type: 'post',
success: function(data){
console.log(data);
},
error: function(a,b,c){
console.log(a,b,c);
}
});
Then you can expect an argument to your controller function:
public function delenq($id){
if($id)
return $this->logins->delenqs($id);
return false;
}
And finally, your model can get a little fixer upper so that it properly returns as well.
public function delenqs($id) {
$this->db->delete('enquiry', array('id' => $id));
return $this->db->affected_rows() > 1 ? true:false;
}
