How to insert and move multiple image using codeigniter?

Question

view:

<script>
    $(document).ready(function(){
        $("#submit").click(function(e){
            e.preventDefault();
            product_name = $("#product_name").val();
            color = $("#colorWell").val();
            $.ajax({
                type:"POST",
                data:{"product_name":product_name, "color":color},
                url:"<?php echo base_url(); ?>admin/products",
                success:function(data){
                    alert(data);
                }
            });
        });
    });
</script>

<input type="text" class="form-control" id="product_name" name="product_name">
<input type="color" id="colorWell" name="color">
<input type="file" id="product_image" name="product_image[]" multiple>
<input type="submit" class="btn btn-primary" id="submit" name="submit">

controller:

public function products()
{
    $product_name = $this->input->post('product_name');
    $color = $this->input->post('color');

    $dataInfo = array();
    $files = $_FILES;
    $cpt = count($_FILES['product_image']['name']);
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES['product_image']['name']= $files['product_image']['name'][$i];
        $_FILES['product_image']['type']= $files['product_image']['type'][$i];
        $_FILES['product_image']['tmp_name']= $files['product_image']['tmp_name'][$i];
        $_FILES['product_image']['error']= $files['product_image']['error'][$i];
        $_FILES['product_image']['size']= $files['product_image']['size'][$i];    

        $this->upload->initialize($this->set_upload_options());
        $this->upload->do_upload();
        $dataInfo[] = $this->upload->data();
    }
    $data = array(
            'product_name' => $product_name,
            'color' => $color,
            'product_image' => implode(",",$dataInfo['product_image']),
        );
    $result_set = $this->db->insert('add_product',$data);
    if($sql == true)
    {
        echo 'New Product Added';
    }
    else
    {
        echo 'Unable to Proceed!';
    }
}

private function set_upload_options()
{   
    $config = array();
    $config['upload_path'] = ''.base_url().'resource/product/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size']      = '0';
    $config['overwrite']     = FALSE;
    return $config;
}

In this code I am trying to insert and wants to move an image into a folder. But Now, problem is that when I click on submit button it throw an error as show in below:

Message: Undefined index: product_image

and query looks:

INSERT INTO `product` (`product_name`, `color`, `product_image`) VALUES ('men hoodies','#004080', NULL)

I don't know where am I doing wrong. So, How can I solve this issue? Please help me.

Thank You

You didn't submit the files data. Use formData to upload files data, and append any other input you like to add to formData :

<script>
    $(document).ready(function(){
        $("#submit").click(function(e){
            e.preventDefault();
            product_name = $("#product_name").val();
            color = $("#colorWell").val();
            var formData = new FormData();
            $.each($("#product_image"), function (i, obj) {
                $.each(obj.files, function (j, file) {                    
                    formData.append('product_image[' + i + ']', file);
                });
            });
            formData.append('product_name', product_name);
            formData.append('color', color);
            $.ajax({
                type:"POST",
                data:formData,
                processData: false,
                contentType: false,
                url:"<?php echo base_url(); ?>admin/products",
                success:function(data){
                    alert(data);
                }
            });
        });
    });
</script>

Send all formdata with file in your ajax.

HTML code like this...

<form method="POST" id="YourFormID" enctype="multipart/form-data">
<input type="text" class="form-control" id="product_name" name="product_name">
<input type="color" id="colorWell" name="color">
<input type="file" id="product_image" name="product_image[]" multiple>
<input type="submit" class="btn btn-primary" id="submit" name="submit">
</form>

Ajax code here....

<script type="text/javascript">
$(document).ready(function(){
    $("#submit").click(function(e){
        e.preventDefault();
        var formData = new FormData($('form#YourFormID')[0]);
        $.ajax({
            type:"POST",
            data:formData,
            url:"<?php echo base_url(); ?>admin/products",
            success:function(data){
                alert(data);
            }
        });
    });
});
</script>

You are not send file in your ajax request. therefore not found index product_image

Answer 3

use array_column like below to add get all product_image values

implode(",",array_column($dataInfo, 'product_image'))
