How to Customize the Block Search Form

Drupal 7

Add the following code snippet to template.php in your theme and you can:

change the submit button to an image

change the text of the submit button to 'Go!' (just remove the // in front of that line of code, and delete the image_button code below it)

add default 'Search this site' text in the input form and make it disappear when users click in the input form

<?phpfunction YOURTHEME_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == 'search_block_form') {
    $form['search_block_form']['#title'] = t('Search'); // Change the text on the label element
    $form['search_block_form']['#title_display'] = 'invisible'; // Toggle label visibilty
    $form['search_block_form']['#size'] = 40;  // define size of the textfield
    $form['search_block_form']['#default_value'] = t('Search'); // Set a default value for the textfield
    $form['actions']['submit']['#value'] = t('GO!'); // Change the text on the submit button
    $form['actions']['submit'] = array('#type' => 'image_button', '#src' => base_path() . path_to_theme() . '/images/search-button.png');

    // Add extra attributes to the text box
    $form['search_block_form']['#attributes']['onblur'] = "if (this.value == '') {this.value = 'Search';}";
    $form['search_block_form']['#attributes']['onfocus'] = "if (this.value == 'Search') {this.value = '';}";
    // Prevent user from searching the default text
    $form['#attributes']['onsubmit'] = "if(this.search_block_form.value=='Search'){ alert('Please enter a search'); return false; }";

    // Alternative (HTML5) placeholder attribute instead of using the javascript
    $form['search_block_form']['#attributes']['placeholder'] = t('Search');
  }
} ?>

Note: When you copy the above snippet to an existing template.php in your theme - you need to replace YOURTHEME with the name of your theme (sure - it's obvious ...). You also have to pay attention to the use of the php brackets - <?php and ?>. The first one <?php should already be at the top of an existing template.php file and the closing one might not be useful if you later add more snippets, etc.
Alternatively and probably better practice is to add the brackets to each snippet individually - this would mean you may have to add a closing bracket ?> to an existing template.php file before adding the above snippet.

Change drupal default search input type Format:

type="text" to type="search"

It's works well in D6 and D7:

/**
* Changes the search form to use the "search" input element of HTML5.
*/
function YOURTHEME_preprocess_search_block_form(&$vars) {
$vars['search_form'] = str_replace('type="text"', 'type="search"', $vars['search_form']);
}

This snippet goes into the template.php file of your theme. In my case it's tao, that is why the function starts with "tao_". You have to rename it to match it your theme name.

Copy folder and files by Command prompt

Copies files and directory trees.

XCOPY source [destination] [/A | /M] [/D[:date]] [/P] [/S [/E]] [/V] [/W]
                           [/C] [/I] [/Q] [/F] [/L] [/H] [/R] [/T] [/U]
                           [/K] [/N] [/O] [/X] [/Y] [/-Y] [/Z]
                           [/EXCLUDE:file1[+file2][+file3]...]

Example---

 xcopy "E:\xampp\htdocs" "D:\xampp\htdocs\sumit /O/E/H/K

 /A           Copies only files with the archive attribute set,
               doesn't change the attribute.
  /M           Copies only files with the archive attribute set,
               turns off the archive attribute.
  /D:m-d-y     Copies files changed on or after the specified date.
               If no date is given, copies only those files whose
               source time is newer than the destination time.
  /EXCLUDE:file1[+file2][+file3]...
               Specifies a list of files containing strings.  When any of the
               strings match any part of the absolute path of the file to be
               copied, that file will be excluded from being copied.  For
               example, specifying a string like \obj\ or .obj will exclude
               all files underneath the directory obj or all files with the
               .obj extension respectively.
  /P           Prompts you before creating each destination file.
  /S           Copies directories and subdirectories except empty ones.
  /E           Copies directories and subdirectories, including empty ones.
               Same as /S /E. May be used to modify /T.
  /V           Verifies each new file.
  /W           Prompts you to press a key before copying.
  /C           Continues copying even if errors occur.
  /I           If destination does not exist and copying more than one file,
               assumes that destination must be a directory.
  /Q           Does not display file names while copying.
  /F           Displays full source and destination file names while copying.
  /L           Displays files that would be copied.
  /H           Copies hidden and system files also.
  /R           Overwrites read-only files.
  /T           Creates directory structure, but does not copy files. Does not
               include empty directories or subdirectories. /T /E includes
               empty directories and subdirectories.
  /U           Copies only files that already exist in destination.
  /K           Copies attributes. Normal Xcopy will reset read-only attributes.
  /N           Copies using the generated short names.
  /O           Copies file ownership and ACL information.
  /X           Copies file audit settings (implies /O).
  /Y           Suppresses prompting to confirm you want to overwrite an
               existing destination file.
  /-Y          Causes prompting to confirm you want to overwrite an
               existing destination file.
  /Z           Copies networked files in restartable mode.
