How To Install LAMP

how to install LAMPLAMP is an acronym which stands for Linux, Apache, MySQL and PHP. The letter P also stands for Perl and Python programming languages. LAMP is a free software stack which powers, primarily, web servers. Most GNU/Linux distributions bundle these packages in the install media and repositories. Let us take a look at how to install LAMP using Fedora. I will restrict the P in LAMP to PHP only for this article. Perl and Python fans, bear with me.

While installing Fedora you can choose to install "Web Sever" which contains these packages. You can install them later also. Let me walk you through the actual steps to get LAMP working on your computer. I assume you are running Fedora 8 on your computer.

1. Launch the terminal by clicking

How To Reset KWallet Password

The problem: You fire a KDE application, the application requires a password to continue, the KWallet window pops up asking for its password. You try your frequently used passwords. None of them work.

This happened to me when I tried to open a password protected PDF document with Okular. I knew I never set the KWallet password on this computer.

The solution: To reset your KWallet password, delete the kwalllet directory.
Type this in your command line:

rm -rf ~/.kde/share/apps/kwallet/

Adding * To Required Zend_Form Field Using CSS

You want to add an asterisk to required fields, huh?

add asterisk to zend form required element

There are many approaches to accomplish this. One among them is setting the requiredSuffix option to the label decorator of the form element. Assuming $element is your Zend_Form_Element object:

<?php
$element
->getDecorator('label')->setOption('requiredSuffix'' * ');
?>

Another option is to add the * while setting the label.

<?php
$element
->setLabel('My Label *')
?>

The third, which I am currently using in one of my Zend Framework powered applications is adding * using CSS. The default label decorator generates the following mark-up.

Autocomplete Example With Zend_Dojo_Form_Element_FilteringSelect And Zend_Dojo_Data

Zend Framework AutoComplete example with Zend_Dojo_Form_Element_FilteringSelect
Zend Framework brings lot of user interface goodies with Zend_Dojo family of classes. In this article let us explore how to build a form element with autocomplete feature.

As a prerequisite you must be familiar with

  • Zend_Controller_Action
  • Zend_Layout
  • Zend_Form

Would it be nice if I tell you that you don't need any JavaScript knowledge? Zend_Dojo empowers PHP programmers to build dynamic and appealing forms without writing a single line of JavaScript.

This example has been tested with Zend Framework 1.7.0.

In this example, we will build a text element where the visitor can either select the user from the drop down list or type the username. While typing the username, the form element generates a drop down list filtering the data from user input. Take a look at the filteringSelect Dijit example to understand the type of form element we will be building.

FilteringSelect differs from Combobox Dojo widget in that, the value of the form element must be provided in the list. Also, you could display the username on the screen and set the 'user id' as the element value.

We will use the autoCompleteDojo action helper to send JSON data.

Let's start coding.
