Filter list items with jQuery

Sometimes while working with list items or contents, we need to filter out the list items or contents for some matching records. We can implement this using jQuery with ease. Here is a little jQuery code snippet to implement local search.

  <script type="text/javascript" 
  <script type="text/javascript">
  $(document).ready(function(e) {
    var val = $(this).val();
      ($(this).text().search(new RegExp(val, "i")) === -1) 
             ? $(this).hide() : $(this).show();

  <input type="text" id="search" />
  <ul class="list">
    <li>New Zealand</li>
    <li>South Africa</li>
    <li>Sri Lanka</li>
    <li>West Indies</li>


  • Australia

Problems and solutions during installing Magento

Different types of issues are found during installing Magento. Here are some compilation of Magento installation problems and their solutions.

Problem 1 : Database server does not support the InnoDB storage engine while installing magento

Solution 1 :

Go To Line 59 of the file app/code/core/Mage/Install/Model/Installer/Db/Mysql4.php
Change this function

    public function supportEngine()
        $variables  = $this->_getConnection()
            ->fetchPairs('SHOW VARIABLES');
        return (!isset($variables['have_innodb']) || $variables['have_innodb'] != 'YES') ? false : true;

With this

    public function supportEngine()
        $variables  = $this->_getConnection()
            ->fetchPairs('SHOW ENGINES');
        return (isset($variables['InnoDB']) && $variables['InnoDB'] != 'NO');

Problem 2: 404 Not Found Error After Installation

Sometimes after installing magento, clicking on any link results in 404 not found error. This happens because the rewrite module of the server is not enabled. Just enable the mod_rewrite and it will work.

Solution 2:

Enable rewrite_module (mod_rewrite) of your Apache Server

List all files of a directory in php

Listing all files of a directory in php is quite easy with php DirectoryIterator class. This class provides a simple interface for viewing the contents of filesystem directories.

Here is a simple php function to list all files of a directory. This is a recursive function so that it will list files of all of its subdirectories too.

   function list_directory_contents($dir){
     $dh = new DirectoryIterator($dir);    
     foreach ($dh as $item) {
         if (!$item->isDot()) {
            if ($item->isDir()) {
            } else {
                echo $dir . "/" . $item->getFilename();
                echo "<br>";

  # Call function

Using MySql replace function

MySql has a very useful function replace() which allows you to replace substring or characters. It is really useful while working with huge database table where you want to update certain values with another value. Its syntax is quite simple.

   REPLACE ( field_name, 'find_string', 'replacement_string' );

To update some values in database table use query as follows using replace function.

   UPDATE tutorials SET topic = REPLACE (topic, 'Php', 'Php MySql');

You can also run a select query using this function if you don't want to update table but want to fetch data as replaced. This will only output replaced values and there will be no changes in database.

   SELECT REPLACE (topic, 'Php', 'Php MySql') as new_topic 
   FROM tutorials 
   WHERE topic = 'Php';
