I usually use joomla and no problem with this...I've searched for something like this but i could'n undertsand anything of what i found....
can someone please explain me how to make the changes and look at them in the browser?

I have a field where users decide what address they want thier profile to be under for example: www.mysite.com/users choice here

I can't seem to find a field that will stop them from using bad characters and spaces, can anyone help?

Thanks

So I'm installing Drupal 7.10 manually on iPage. I'd rather not use their automated tool b/c I prefer to have maximum control and am concerned with customization issues afterward. I will, though, if it turns out doing this manually is too much of a pain. Anyway, I'm on the database settings page, and here are my settings:

database name: drupaldata
user: myusername
pass: mypass
host: custsql-ipg17.eigbox.net (I got this from phpmyadmin)
port: 3307
prefix: N/A

I am getting the following error:

I'm completely new to Drupal and I would greatly appreciate any advice you would be willing to give me to fix this issue.

I was installing Ubercart and all the modules necessary to run it. After I tried to enable the modules, I received the following:

"Fatal error: Class 'RulesCondition' not found in C:\xampp\htdocs\drupal7.10\sites\all\modules\rules\rules.module on line 272"

Since I'm really new to Drupal and still learning, I'm quite unsure of how to resolve this issue. I would appreciate any help. Thank you very much.

I've been struggling a bit to understand the relationship between custom widgets that apply to fields (via hook_field_widget_info()) and regular form API elements (via hook_element_info()) - is there any way these interoperate, or are they completely separate worlds?

Hi,
is there any "hello world" example code how to integrate custom entity to views?

I have achieved creating new view with "Show" set to my entity. But when I want to edit my view, I don't see any filter criteria or fields to add. The View Format I have set as follows:

Format:Unformatted list
Show: Entity

When I create some entity content, the view does display each content as "Unlabeled". So at least it registers my entity content.

I have this implementation of hook_entoty_property_info:

<?php
function upozornenia_entity_property_info() {
     $info = array();
  $properties = & $info['upozornenie']['properties'];

  $properties['nid'] = array(
    'label' => t("Node ID"),
    'type' => 'integer',
    'description' => t("The unique ID of the node."),
    'schema field' => 'nid',
  );
  $properties['up_id'] = array(
    'label' => t("ID upozornenia"),
    'description' => t("ID upozornenia"),
     'type' => 'integer',
    'schema field' => 'up_id',
  );
  $properties['author'] = array(
    'label' => t("Author"),
    'type' => 'user',
    'description' => t("The author of the upozornenie."),
    'required' => TRUE,
    'schema field' => 'uid',
  );

  return $info;
 }
?>

As I understand, array items in hook_entity_property_info should automatically show in views as filters ad fields. Am I correct?
