I am very new to Codeigniter. I m trying to create a form with some text input field along with two image upload field. The image uploading working fine but the text input field value are not coming. Can anyone please check my code and tell me where I am doing wrong Here is my Code:
前端
<body>
<div class="custom-container">
<div id="msg"></div>
<form id="product-upload" action="/index.php/uploadproduct/upload" method="POST" accept-charset="utf-8" enctype="multipart/form-data"">
<div class="form-group">
<label for="product-name">Product name</label>
<input type="text" name="product_name" class="form-control">
</div>
<div class="form-group">
<label for="product-name">Product Code</label>
<input type="text" name="product_code" class="form-control">
</div>
<div class="form-group">
<label for="product-name">Product Link</label>
<input type="text" name="product_link" class="form-control">
</div>
<div class="form-group">
<label for="product-image">Product image</label>
<input type="file" id="product-image" name="product_image" class="form-control">
</div>
<div class="form-group">
<label for="product-name">Product Screenshots</label>
<input type="file" id="product-screen" name="product_screen" class="form-control" multiple>
</div>
<div class="form-group">
<input id="add-product" type="Submit" class="btn btn-primary" value="Add new product">
</div>
</form>
</div>
</body>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('#add-product').click(function(e){
e.preventDefault();
var formData = new FormData();
//for product profile images
var productProfile = $('#product-image').prop('files')[0];
formData.append('file',productProfile);
// for product detail image
var imageCount = document.getElementById('product-screen').files.length;
for (var i = 0; i< imageCount; i++) {
formData.append("files[]", document.getElementById('product-screen').files[i]);
}
//AJAX Call
$.ajax({
url: 'http://localhost/ci/index.php/uploadproduct/upload/', // point to server-side controller method
dataType: 'text', // what to expect back from the server
cache: false,
contentType: false,
processData: false,
data: formData,
type: 'post',
beforeSend: function() {
// setting a timeout
$('#msg').html('Loading');
},
success: function (response) {
$('#msg').html(response); // display success response from the server
$('input').attr('value').html();
},
error: function (response) {
$('#msg').html("no response"); // display error response from the server
}
});
});
});
</script>
控制器脚本是这个
public function upload(){
$uploadData = "";
//Get the details
$productName = $_POST['product_name'];
$productCode = $this->input->post('product_code');
$productLink = $this->input->post('product_link');
$uploadData = $productName.','.$productCode.','.$productLink;
// setting cofig for image upload
$config['upload_path'] = 'uploads/profile/';
$config['allowed_types'] = '*';
$config['max_filename'] = '255';
$config['encrypt_name'] = TRUE;
//$config['max_size'] = '1024'; //1 MB
// Get the profile image
$errorMsg = "";
if (isset($_FILES['file']['name'])) {
if (0 < $_FILES['file']['error']) {
$errorMsg = 'Error during file upload' . $_FILES['file']['error'];
} else {
if (file_exists('uploads/profile/' . $_FILES['file']['name'])) {
$errorMsg = 'File already exists : uploads/profile/' . $_FILES['file']['name'];
} else {
$this->load->library('upload', $config);
if (!$this->upload->do_upload('file')) {
$errorMsg = $this->upload->display_errors();
} else {
$data = $this->upload->data();
$errorMsg = 'File successfully uploaded : uploads/profile/' . $_FILES['file']['name'];
$uploadData = $uploadData.','.$data['full_path'];
}
}
}
} else {
$errorMsg = 'Please choose a file';
}
//upload product screenshots
$config['upload_path'] = 'uploads/';
if (isset($_FILES['files']) && !empty($_FILES['files'])) {
$no_files = count($_FILES["files"]['name']);
$link="";
for ($i = 0; $i < $no_files; $i++) {
if ($_FILES["files"]["error"][$i] > 0) {
$errorMsg = "Error: " . $_FILES["files"]["error"][$i] . "<br>";
} else {
if (file_exists('uploads/' . $_FILES["files"]["name"][$i])) {
$errorMsg = 'File already exists : uploads/' . $_FILES["files"]["name"][$i];
} else {
$fileOriginalNmame = $_FILES["files"]["name"][$i];
$explodeFile = explode(".",$fileOriginalNmame);
$fileExtenstion = end($explodeFile);
$fileName = md5(md5(uniqid(rand(), true)).$_FILES["files"]["name"][$i]).'.'.$fileExtenstion;
move_uploaded_file($_FILES["files"]["tmp_name"][$i], 'uploads/' . $fileName);
$link= $link.$fileName.',';
}
}
}
$uploadData =$uploadData .','. $link;
$errorMsg = $uploadData;
} else {
$errorMsg = 'Please choose at least one file';
}
echo $errorMsg;
}
如果有人可以改进我的控制器代码那将非常有用的tnx。
And if anyone can improve my controller code that will be very helpful tnx.
推荐答案
FormData（）方法：
根据我们的定义 .FormData（）在<$ c中提交元素数据$ c>键/值表单。 Form元素必须具有name属性。 FormData（）的一个优点是，您现在可以在下一页上发布文件。
As per our definition .FormData() submit a element data in a Key/Value form. The Form element must have a name attribute. One advantage of FormData() is now you can post a files on next page.
简单语法：
var formData = new FormData(form);
精彩积分：
-
此方法会发布文件。
This method does post files.
此方法使用Get& amp;发布方法包括文件。
This method post complete form using Get & Post method including files.
var formData = new FormData（）;
var formData = new FormData();
formData.append（'username' ，'joe'）;
formData.append('username', 'joe');
此外，您可以使用 FormData.append 。
所以你的代码坏了，因为你需要传递输入值作为你的密钥/对格式错过了文件。
So your code broke because you need to pass value of input as key/pair format that you missed except for file.
希望这会对你有帮助。
请找到下面的解决方案。
$(document).ready(function(){
$('#add-product').click(function(e){
e.preventDefault();
var formData = new FormData();
//for product profile images
var productProfile = $('#product-image').prop('files')[0];
formData.append('file',productProfile);
// for product detail image
var imageCount = document.getElementById('product-screen').files.length;
for (var i = 0; i< imageCount; i++) {
formData.append("files[]", document.getElementById('product-screen').files[i]);
}
var inputs = $('#product-upload input[type="text"],input[type="email"]');
$.each(inputs, function(obj, v) {
var name = $(v).attr("name");
var value = $(v).val();
formData.append(name, value);
});
//AJAX Call
$.ajax({
url: 'http://localhost/ci/index.php/uploadproduct/upload/', // point to server-side controller method
dataType: 'text', // what to expect back from the server
cache: false,
contentType: false,
processData: false,
data: formData,
type: 'post',
beforeSend: function() {
// setting a timeout
$('#msg').html('Loading');
},
success: function (response) {
$('#msg').html(response); // display success response from the server
$('input').attr('value').html();
},
error: function (response) {
$('#msg').html("no response"); // display error response from the server
}
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="custom-container">
<div id="msg"></div>
<form id="product-upload" action="/index.php/uploadproduct/upload" method="POST" accept-charset="utf-8" enctype="multipart/form-data">
<div class="form-group">
<label for="product-name">Product name</label>
<input type="text" name="product_name" class="form-control">
</div>
<div class="form-group">
<label for="product-name">Product Code</label>
<input type="text" name="product_code" class="form-control">
</div>
<div class="form-group">
<label for="product-name">Product Link</label>
<input type="text" name="product_link" class="form-control">
</div>
<div class="form-group">
<label for="product-image">Product image</label>
<input type="file" id="product-image" name="product_image" class="form-control">
</div>
<div class="form-group">

<input type="file" id="product-screen" name="product_screen" class="form-control" multiple>
</div>
<div class="form-group">
<input id="add-product" type="Submit" class="btn btn-primary" value="Add new product">
</div>
</form>
</div>
