I am attempting to read an Excel File using PHPExcel Lib through an ajax call. However, the read attempt is causing an error of PHPExcel_Reader_Exception: Could not open for reading! File does not exist.
My index.php is as follows:-
<?php
ob_start();
ini_set("xdebug.var_display_max_children", -1);

A screenshot of the error displayed is this
Where is the error? Or is it that PHPExcel cannot be used with ajax?
general advice
you could use browser debug console (F12 if chrome) to see if file actually got upload
you could var_dump($_FILES) to see actually what server got
this has nothing to do with begin ajax vs PHPExcel, I think you got it wrong at the basic level of how to handle form data in PHP
and on your question, since your file input is like this
<input type="file" id="uploadfile" name="uploadfile"
variable name must be
$_FILES["uploadfile"]
and "name" is just name, for actual file you'll have to use
$_FILES["uploadfile"]["tmp_name"]
read this for more info on $_FILES array structure
Array
(
[file1] => Array
(
[name] => MyFile.txt (comes from the browser, so treat as tainted)
[type] => text/plain (not sure where it gets this from - assume the browser, so treat as tainted)
[tmp_name] => /tmp/php/php1h4j1o (could be anywhere on your system, depending on your config settings, but the user has no control, so this isn't tainted)
[error] => UPLOAD_ERR_OK (= 0)
[size] => 123 (the size in bytes)
)
)
When I type in my select box the result always show "The result cannot be load". I am using CodeIgniter for my framework and select2 in my select box and am a newbie in CodeIgniter and Select2. I have already search it through all articles that can be related to my problem but it still can't work. I think I messed my ajax but I don't know how and where I should fix it.
Here is my controller
<?php
class Admin extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('admin_model');
}
function search_book(){
$booksClue = $this->input->get('booksClue');
$data_book = $this->admin_model->get_book($booksClue, 'id_book');
echo json_encode($data_book);
}
}
?>
Here is my model
<?php
class Admin_model extends CI_Model{
function get_book($booksClue, $column){
$this->db->select($column);
$this->db->like('id_book', $booksClue);
$data = $this->db->from('book')->get();
return $data->result_array();
}
}
?>

Big thanks for your help!
Update your model function like below:
function get_book($booksClue, $column){
$this->db->select($column);
$this->db->from('book');
$this->db->like('id_book', $booksClue);
return $this->db->get()->result_array();
}

$("#email").val('');
$("#img").val('');

Am trying to upload image using ajax php and jquery what am i doing wrong here. the image should be uploaded without refreshing the page. i have tried the above code. if your see any prolem, help!!
The thing is i want to move the uploaded file to the upload folder and insert the image name to the database as a BLOB.
You can use FormData objects but you need to write the code in plain Javascript because I think JQuery doesn't support it yet. Please read this for more information https://developer.mozilla.org/en-US/docs/Web/API/FormData/Using_FormData_Objects

Please any one help me
The problem is very small.
This line:
$("cart_quantity_input").val(data.qty);
just you forgot to add . before cart_quantity_input
So change it to be :
$(".cart_quantity_input").val(data.qty);
