Hi All,
I am new user of yii,
I want to upload a file in to my server and files address have to save in a database.
please any one can help me how can i do step by step.Hi and welcome to the forum…
Since you are new… first thing (if you did not already done it) is to read the Definitive guide to Yii so that you get an overview of how Yii works…
For the upload check this wiki article - http://www.yiiframew…e-using-a-model
And note that you posted in the Yii 1.0 forum - this version is no more maintained.
ya but what about database…?
Please explain more… what you mean with "what about database?"
Have you read the wiki article… the filename is saved in the database with $model->save()… the file is saved wherever you decide with $model->image->saveAs()
Isn’t that what you asked for?
This is my controller file
<?php

This is my AR

and this is view code

I got this error:
Please fix the following input errors:
Image cannot be blank.
Image cannot be blank.When you post your code it would be good to use the code button ( <> in the editor toolbar) as this way the code is practically unreadable…
and please do not post so big portion of code… nobody has time to read all that code… you just need to post the relevant code…
as for the message there are already many threads on the forum about that… try to search the forum…
i did it
my controller code it works…
if(isset($_POST['Demo']))
{
$model->attributes=$_POST['Demo'];
$model->image=CUploadedFile::getInstance($model,'image');
$model->img=$model->image;
if($model->save())
{
$model->image->saveAs('/var/www/demo/images/'.$model->image);
$this->redirect(array('demo/create'));
}
}
