View Full Version : Very simple Writer example?

14 Aug 2012, 2:28 AM
Hey guys,

I am looking for a very simple example for using a writer, to write data into a server-side file. Maybe, just one textbox, which text is loaded into the file. Does anyone know such a simple example? I just want to understand the function to write the data.

All examples I found, including the Sencha example 'Writer', are very long.I am new to Extjs and this code very complicated.

Please help me, if possible. I really need this code for an important project.

Thanks, Victoria

ExtJs Writer classes don't actually 'write files' on the server-side, they just enforce that the submitted data is formatted in a particular manner. Your server-side code is responsible for writing the submitted data to a file on its local filesystem.

I know that a server-side-code is needed to write the data to the file, but I does'nt understand how this all works together and with a large example it's really hard to find out how it works.

the 2 examples are greate, but do I need a mysql database to test the examples?

Your examples are great, thank you very much !! :D

I fixed the problem with the database, but I still get this error:

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\example2\save_product.php on line 71

This is the code:

while($rec = mysql_fetch_array($result,MYSQL_ASSOC)){
$arr[] = $rec; };

The data is loaded into the database, but the grid is not automatically actualized.

Can you tell me, what is wrong?

These are based on mysql, but you can replace with any DB and change the syntax as needed.

What is the value of $result. It should be a valid result from the above line.
You may have to eval each var to see what is return. The result set $data should be populated.
