Media Uploader Crunching Issue

by

Problem

WordPress has a bug.  When uploading an image (even a small,  1KB image) the Media uploader stalls and freezes in when Crunching is 100%.   This problem happens in both the flash and html uploader.  In the HTML uploader you can see a 500 Internal Server Error.

 

Solution

There are 2 different problems that can cause this issue.

One is your server or hosting provider.  GoDaddy has since said they have fixed this issue.  However, when I contacted support they said to disable Fast CGI for PHP.  I responded with a link to the article above.  They then helped me out by telling me to update my php5.ini or php.ini file.   You’ll find that this solution was found on the WordPress forums also where you set the memory_limit and max_execution_time higher.  So in your php.ini or php5.ini if you use php5 (that’s important!  trust me, I’ve been frustrated with that before) add the following lines:
max_execution_time = 600
memory_limit =128M
upload_max_filesize = 2M

Adjust as needed.  You may also have to End your Web Process to quickly see changes.  See godaddy support forums for this.

The 2nd issue with this bug is a more frustrating and disappointing one.  I found out that WordPress uses the delete_posts capability to determine whether a user can delete a media file or not.  Well, guess what, it also uses the edit_posts capability when it crunches the file too.  So if you have a problem where only the Administrator can upload media files fine, check your user’s capabilities.  On a side note, to delete media the user needs the delete_posts capability.

 

 

 

Creating a New Yii Application – Quick Reference

by

This post is here to remind me how to create a Web application using the Yii framework.   It will be updated from time to time.  This is assuming the yii framework is inside WebRoot

Here is how to create a new webapp named “sampleApp”.

Open your command prompt or Terminal
cd WebRoot
php YiiRoot/framework/yiic.php webapp sampleApp

configure the config files located at:
sampleApp/protected/config/main.php
sampleApp/protected/config/test.php

Now edit test.php and override your test database connection by entering info into the ‘db’ array item.

 

PHP ini overriding

by

On shared hosts, overriding the php.ini file can be frustrating.  Sometimes it works, sometimes it doesn’t.  It’s up to the host provider.   This post will keep a record of what hosts need what type of requirements and will be updated from time to time.  This overriding php.ini file can be a partial override like so:

[PHP]
; Maximum size of POST data that PHP will accept.
post_max_size = 20M
; Maximum allowed size for uploaded files.
upload_max_filesize = 20M

 

GoDaddy

The php.ini file needs to be named php5.ini if you are using PHP version 5.x.  Sometimes you’ll need to restart the web process in the control panel.  It is located under the “System Processes” icon.   Once in System Processes click on “End Web”.

get_permalink returning wrong link in excerpt

by

Problem

In WordPress, the default theme, twenty_eleven, has a function called twentyeleven_continue_reading_link.  This method is supposed to return the permalink for the current excerpt.  However if you use setup_postdata() and call the_excerpt() the permalink will return the current page’s permalink, not the excerpt’s permalink.

 

Solution

The reason it returns the current page’s permalink is because get_permalink() gets the permalink for $post which is the current page.  To resolve this, I looked in setup_postdata to see what it is doing.  setup_postdata is setting a global $id variable each time you call it.  This means that same $id variable is the excerpts id.  Which means in the twentyeleven_continue_reading_link method, instead of calling get_permalink(), you can declare the global $id variable and call get_permalink($id).  See the updated method below.

 

function twentyeleven_continue_reading_link() {
        global $id;
        return ' ' . __( 'Continue reading →', 'twentyeleven' ) . '';
}
