PHP

Hi, I am Sumaiya Javed PHP Web developer and this is my personal blog or collection of tutorials, scripts, tips and tricks used or created personally by me in my five years of web development. And yeh ... click here to view my online portfolio, for any freelancing projects.

Try this screencast for the calendar http://www.youtube.com/watch?v=qO4TeEydtMs

Use calendar popup to have the effect on the calendar view as well (you know what i mean when you have played with the calendar module once).

I wanted to display a block using views where the taxonomy parent and child needed to displayed in separate fields.

Eg Books Parent term: Adult and Child Term: Fiction

So block view should be such that

Book Title – Parent Term – Child Term ie Eclipse – Adult – Fiction

To achieve this Go to Views

• Add “Relationships”
  • Select “Taxonomy: Parent Term” (use the default settings)
• Add Fields
  • Select “Taxonomy: Term”
  • Relationship: Parent
• Add Fields
  • Again Select “Taxonomy Terms”
  • Relationship: Do not use a relationship

Now we have reached our goal … simple but takes some digging …

The function that displays the url of the current page

request_uri();

To use it in if statement; emplor strpos php function

$url = request_uri();
if (strpos($url, “contact”)) { print “this the contact page”; }

I have faced this horrible issue of transferring database from either my localhost to the server or transferring from one hosting server to another.

The even for small drupal sites the database gets so huge that transferring is not possible at times. There is a timeout error and when I tried to upload per table, life became unbearable.

So i came with this solution hoping to help whoever is stuck with dilemma.

The solution is just to import first the database structure and then the database data excluding all the cache tables and watchdog table. Probably it is an obvious solution but I literally sweated to get to it.

The opacity feature of css does not work on internet explorer IE, to overcome that use filter option.

Eg

.change_opacity {
  opacity: 0.5;
  filter: alpha(opacity = 50);
}

Note: The value of filter is different from opacity

When using the error reporting feature of drupal I faced my theme getting screwed up, the regions and block of left side went missing. After searching drupal posts etc I found the following solution for drupal 6:

Add the following function in your theme’s template.php file:

I wanted to the shopping cart to look more elegant so I used the sliding effect of jquery, css opacity transparency and reduce the summary to enable a one line heading “shopping cart” and when it is clicked a curtain or sliding effect is enabled showing a see through cart.

Sliding Effect:

1. Open file uc_cart_block.js located in modules/ubercart/uc_cart
2. Go to line 43 and replace
3. $(’#cart-block-contents’).toggle(’slow’);
   with
   $(’#cart-block-contents’).slideToggle(’slow’);

Transperancy

Open style.css of your theme and add the following:

#cart-block-contents  {
background:none repeat scroll 0 0 #FFFFFF;
border:3px solid black;
margin-top:-14px;
opacity:0.9;
position:absolute;
z-index:100000;
}

Reduce the cart summary

Open template.php in your theme (if the file is missing create it) and add the following function:

function myuniform_uc_cart_block_content($help_text, $items, $item_count, $item_text, $total, $summary_links) {
$output = ”;

// Add the help text if enabled.
if ($help_text) {
$output .= ‘<span>’. $help_text .’</span>’;
}

// Add a wrapper div for use when collapsing the block.
$output .= ‘<div id=”cart-block-contents”>’;

// Add a table of items in the cart or the empty message.
$output .= theme(’uc_cart_block_items’, $items);
$output .= theme(’uc_cart_block_summary’, $item_count, $item_text, $total, $summary_links);

$output .= ‘</div>’;

// Add the summary section beneath the items table.

return $output;
}

Note: myuniform is the name of my theme, so write just replace it with your theme name.

The option_image module which changes image when an attribute option is changed does not work on my theme but is working with garland.

The solution for that lies in the node.tpl file .. copy paste the node.tpl from garland to your theme and start customizing it. My error was because i had skipped id=”node-<?php print $node->nid; ?>” and i had removed the class=”content clear-block” from <div> printing the $content.

If you are using the grid layout override this function theme_uc_catalog_product_grid($products) and where it says $imagelink=”; give the path of your image.

Now how it goes is that you open the template.php (if it is not there create it) in your theme folder and enter the above function with your changes. Click here to view the list of other theamable ubercart functions.

Eg: Note: myuniform is the name of my theme

<?php
//theme the product image for the catalog basically to add a default image when product image not present
function myuniform_uc_catalog_product_grid($products) {
$product_table = ‘<div><table>’;
$count = 0;
$context = array(
‘revision’ => ‘themed’,
‘type’ => ‘product’,
);
foreach ($products as $nid) {
$product = node_load($nid);
$context['subject'] = array(’node’ => $product);

if ($count == 0) {
$product_table .= “<tr>”;
}
elseif ($count % variable_get(’uc_catalog_grid_display_width’, 3) == 0) {
$product_table .= “</tr><tr>”;
}

$titlelink = l($product->title, “node/$nid”, array(’html’ => TRUE));
if (module_exists(’imagecache’) && ($field = variable_get(’uc_image_’. $product->type, ”)) && isset($product->$field) && file_exists($product->{$field}[0]['filepath'])) {
$imagelink = l(theme(’imagecache’, ‘product_list’, $product->{$field}[0]['filepath'], $product->title, $product->title), “node/$nid”, array(’html’ => TRUE));
}
else {
$imagelink = ‘<img src=”/uniform/sites/default/files/default-small-uniform.jpg”>’;
}

$product_table .= ‘<td>’;
if (variable_get(’uc_catalog_grid_display_title’, TRUE)) {
$product_table .= ‘<span>’. $titlelink .’</span>’;
}
if (variable_get(’uc_catalog_grid_display_model’, TRUE)) {
$product_table .= ‘<span>’. $product->model .’</span>’;
}
$product_table .= ‘<span>’. $imagelink .’</span>’;
if (variable_get(’uc_catalog_grid_display_sell_price’, TRUE)) {
$product_table .= ‘<span>’. uc_price($product->sell_price, $context) .’</span>’;
}
if (module_exists(’uc_cart’) && variable_get(’uc_catalog_grid_display_add_to_cart’, TRUE)) {
if (variable_get(’uc_catalog_grid_display_attributes’, TRUE)) {
$product_table .= theme(’uc_product_add_to_cart’, $product);
}
else {
$product_table .= drupal_get_form(’uc_catalog_buy_it_now_form_’. $product->nid, $product);
}
}
$product_table .= ‘</td>’;

$count++;
}
$product_table .= “</tr></table></div>”;
return $product_table;
}

?>
