Yii - How to upload a csv to save in database? - php

Question

i'm with some troubles figuring out how to read the CSV file that I upload, probably i'm missing something in my Controller code.
public function actionImport() {
$model = new Produtos;
$this->render('import', array('model' => $model) );
if( isset($_FILES['csv_file']) ) {
$handle = fopen($_FILES['csv_file']['tmp_name'], 'r');
if ($handle) {
while( ($line = fgetcsv($handle, 1000, ";")) != FALSE) {
$model->codigo = $line[0];
$model->nome = $line[1];
$model->descricao = $line[2];
$model->stock = $line[3];
$model->data_reposicao = $line[4];
$model->save();
}
}
fclose($handle);
}
}
This is only saving me the last line in the CSV... please some help!
Any help will be really appreciated.
Thank you

Answer 1

I think You missed the name of file, try $_FILES['csv_file']['tmp_name']
http://php.net/manual/en/features.file-upload.post-method.php for reference.
Also Yii does provide file handling, check http://www.yiiframework.com/doc/api/1.1/CUploadedFile for reference

Answer 2

Don't forget to check whether your data is successfully validated or not.
Insert this code between yours:
$model->data_reposicao = $line[4];
if (!$model->validate())
throw new Exception("Validation failed.");
$model->save();
So you can see what's going wrong.

Answer 3

$_FILES is an array, which contains ['element_name']-array. In your case $_FILES is an array of $_FILES['csv_file']['name'], $_FILES['csv_file']['type'], $_FILES['csv_file']['error'], $_FILES['csv_file']['size'] and $_FILES['csv_file']['tmp_name'].
So for short; $_FILES['csv_file'] is an array.

Answer 4

you are saving the same model instance again and again... that is why only the last line gets saved... you will have to create a new model for every line, i.e. in your while loop, add $model = new Produtos;

Answer 5

You need to initialise your model object every time when you need to insert your row into table. The code should be like:
public function actionImport() {
$model = new Produtos;
$this->render('import', array('model' => $model) );
if( isset($_FILES['csv_file']) ) {
$handle = fopen($_FILES['csv_file']['tmp_name'], 'r');
if ($handle) {
while( ($line = fgetcsv($handle, 1000, ";")) != FALSE) {
$modeln = new Produtos;
$modeln->codigo = $line[0];
$modeln->nome = $line[1];
$modeln->descricao = $line[2];
$modeln->stock = $line[3];
$modeln->data_reposicao = $line[4];
$modeln->save();
}
}
fclose($handle);
}
}

Answer 6

I know this is an old post, but I just came across this and just wanted to help someone who might be having the same issue (b/w issue is not with CSV or file upload)
Issue is with how Yii handles saving
You need to set isNewRecord attribute to true and primary key to NULL of model object before saving to save a new record everytime.
$model->PRIMARYKEYCOLUMN = NULL; //Replace PRIMARYKEYCOLUMN with the name of column
$model->isNewRecord = true;
$model->save();
You need to do above step whenever you are saving rows in loop.

$handle = fopen($_FILES['Userimportcsv']['tmp_name']['csv_file'], 'r');
if($handle) {
$row = 1;
while( ($line = fgetcsv($handle, 1000, ",")) != FALSE) {
if($row>1) {
$newModel = new Countries;
$newModel->countryName = $line[0];
$newModel->status = $line[1];
$newModel->save();
}
$row++;
}
}
fclose($handle);
