Fatal error: Call to undefined function imageftbbox() in /Users/[whatever]/Sites/phpmyadmin/libraries/chart/pChart/pChart.class on line 1118

From that point forward PMA was useless in any browse view. Reinstallation didn’t fix it either. The problem occurred because my PHP installation wasn’t compiled with Freetype support. Great… I don’t even want that, I just want PMA to work about in 5 mins time.

Fix: Turns out that clicking the box saves some data in a session cookie. Deleting the cookie named phpMyAdmin fixed the problem for me. If you use Firefox, Chrome or Safari this is easily done in Developer Tools / Element Inspector. If you use IE, get off my site!

Fix: Replace fuse 21.. simple but effective.

Fix: Adding this to your theme’s (or child-theme’s) functions.php removes the page and the menu link:

function nuke_menu_items(){
remove_menu_page( 'link-manager.php');
//remove_menu_page( 'upload.php'); //remove other items etc etc
}
add_action('admin_menu', 'nuke_menu_items', 999 );

Lid Fix: The loose lid can be fixed by liberally applying Petroleum Jelly around the lid. Vaseline the company make Petroleum jelly readily available in chemists and supermarkets, and it’s commonly used on babies apparently for some reason or other (no idea).

Baggy Grommet Fix: Place some PVC tape around the bottom tube of the airlock where it passes through the grommet. Use about 5-8CM of tape to start with, wrapped on in a cone moving towards the top of the trap so that it gets thicker. Then when the trap is re-inserted into the grommet, it will expand the rubber more and make a better seal.

Note: This has only been a problem with cheap kit that uses rubber grommets and press on lids. Better fermenting bins have screw tops and large rubber bungs to place the airtrap in.

Fix: Gmail is really powerful when the text search box is used. There are various advanced search operators but the ones that help here are ‘before:’ and ‘after:’. When twinned with ‘from:’ or ‘to:’ it returns exactly what you want.

Examples:
A certain date range:

after:2010/03/31 before:2011/04/01

The phrase “invoice” in a certain date range:

after:2010/03/31 before:2011/04/01 invoice

From an individual in a range:

after:2010/03/31 before:2011/04/01 from:wave@thesea.com

<?php if(shopp('category','hascategories')): ?>
  <?php while(shopp('category','subcategories')): ?>
    //display stuff
  <?php endwhile; ?>
<?php endif; ?>

…displays all subcast AND their subcats.

Fix: I decided to add a new tag, called shopp(‘subcategory’, ‘depth’) that would return the category depth. That way in the loop above this would show only immediate children:

<?php if(shopp('category','hascategories')): ?>
  <?php while(shopp('category','subcategories')):
    $depth = shopp('subcategory', 'depth', 'return=true');
    if($depth!=0):
      continue;
    endif; ?>
   //else display stuff
<?php endwhile; ?>
<?php endif; ?>

Adding the new tag: Open the theme’s functions.php file and add this:

add_filter('shopp_tag_category_depth','return_cat_depth',10, 3);
add_filter('shopp_tag_subcategory_depth','return_cat_depth',10, 3);
function return_cat_depth($result, $options, $Category) {return $Category->depth;}

…once that’s added, shopp(‘subcategory’, ‘depth’) can be used anywhere in the Shopp templates.

Note: In Shopp 1.2 the hook is created differently. Thanks to Jon Davies for pointing out that the hook would now be shopp_themeapi_{object name}_{property} and defined in defined in shopp/api/theme.php.

<?php while(shopp('category','subcategories')): ?>
    <?php shopp('subcategory','name'); ?> (<?php shopp('subcategory','total'); ?>)
<?php endwhile; ?>

Fix: For the products to be countable, the ‘hasproducts‘ tag has to be called with the ‘load’ option like so:

<?php while(shopp('category','subcategories')): ?>
    <?php if(shopp('subcategory','hasproducts','load=prices,images')): ?>
        <?php shopp('subcategory','name'); ?> (<?php shopp('subcategory','total'); ?>)
    <?php endif; ?>
<?php endwhile; ?>

Note: The docs refer to ‘category’ tags. Each category tag has an ideantical subcategory tag. For example and both work when used in the correct context.

<ul class="variations">
  <?php shopp('product', 'variations', 'mode=multiple&label=true&defaults=Select an option&before_menu=<li>&after_menu=</li>'); ?>
</ul>

And this outputs a list that shows options as “Option Label (price)”.

Fix: The code above can be replaced with this code to manually create the same thing, giving complete control over output:

<ul class="variations">
    <li>
    <label for="options-1">Quantity</label>
    <select name="products[<?php shopp('product', 'id'); ?>][options][]" class="category-catalog product<?php shopp('product', 'id'); ?> options" id="options-1">
    <option value="">Select an option</option>
    <?php
        $i=1;
        while (shopp('product', 'variations')): ?>
        <option value="<?php echo $i;$i++; ?>"><?php shopp('product', 'variation', 'label'); ?></option>
    <?php endwhile; ?>
    </select>
    </li>
</ul>

The $i;$i++ was a bit of a work-around as I couldn’t get it to work with variation ID, so if you know a better way, please tell us below!

Fix: There is however a breadcrumb template tag that stores the category name that a user us currently viewing, so that if they then click on a product, the hierarchical parent category can be displayed in the breadcrumb.

This functionality can be used in a new custom tag. Jon Davis the lead developer of Shopp helped me a lot today as I was barking up the wrong tree going about it the wrong way.

Add this to your theme’s functions.php:

add_filter('shopp_tag_catalog_lastcat','get_last_cat');
function get_last_cat ($result,$options,$Object) {
    $Storefront = ShoppStorefront();
    if (false === $Storefront) return false;
    $category = $Storefront->breadcrumb;
    return $category;
}

Then anywhere in your Shopp templates you can do this to return the category part of the current breadcrumb e.g “Smalls” in Home > Smalls > Purple Pants :

<?php
//echo it out straight away..
shopp('catalog','lastcat');
 
// return it for use..
$lastcat = shopp('catalog','lastcat','return=true');
?>

Hope that helps someone, props go to JD for getting it working!

Notice: unserialize() [function.unserialize]: Error at offset 111 of 118 bytes in /home/maxwell4/public_html/main/wp-content/plugins/shopp/core/model/Settings.php on line 228

…she had done a ‘find and replace’ in a SQL DB dump to change her domain name, boogered it up accidentally, and needed an explanation. The answer I gave applies any time that error occurs in PHP, so i thought it was worth posting here!

Reason: Arrays are often serialized so that they can be stored in a database text field. If you change the data within a serialized array, without changing the character count, you will get the error above.

For example, try this:

1
2
3
4

<?php
$thing = array('one','two');
echo serialize($thing);
?>

This will echo out the following: a:2:{i:0;s:3:”one”;i:1;s:3:”two”;}
Now… if you stored that in a database, you could then retrieve it later and unserialize() it to get your array back. wohoo!

In that serialized data, s:3:”one” means that the first element in the array is a string, and that it’s 3 characters long. Now.. if you manually changed “one” to “otherone” like this a:2:{i:0;s:3:”otherone”;i:1;s:3:”two”;} then when you ran it through unserialize() to retrieve your array, you would get the error were talking about.

Fix: To correct this you would need to update the string length also like so: a:2:{i:0;s:8:”otherone”;i:1;s:3:”two”;} because “otherone” is actually 8 characters long. See? Good!
