WordPress Recent Posts Korn Shell Tutorial<\/p><\/div>\n

Today we’re rearranging how our WordPress<\/a>.org blog Recent Posts widget images are created via crontab<\/a> and curl<\/a> in a scheduled way on this newer Apache\/PHP\/MySql Linux web server, as we talked about with WordPress Recent Posts Navigation Issue Tutorial<\/a> too.<\/p>\n

For a reason still unclear to us the recent-posts-2.php exec<\/a> call of ImageMagick<\/a> convert creation of thumbnails failed, after a failure creating zero length non-thumbnail images (fixed now using PHP copy<\/a> rather than file_put_contents<\/a>), though it works on the command line in a Linux environment with that same priviledged username.<\/p>\n

Especially given that thumbnail usage is optional in the WordPress Recent Posts functionality, rather than spend more time unhappy<\/sup>, we’re happy if a beginning to Korn Shell<\/a> (which the PHP now writes in a way so that the execution of the Korn Shell causes it’s self destruction<\/a>) involvement …<\/p>\n

<\/img><\/p>\n

… within the crontab purview.<\/p>\n

Hopefully we’ll have good news tomorrow that it worked as a new approach.<\/p>\n

WordPress Recent Posts Navigation Issue Tutorial<\/p><\/div>\n

Back to the topic of “WordPress Blog Recent Posts” (and its relationship to the RJM Programming Landing Page) last referenced at WordPress Recent Posts Widget Caching Issues Tutorial<\/a>, is today’s fix to an iPhone usage hashtag navigational annoyance that would leave the Blog Title lose a bit of its visibility up the top when navigated to via the RJM Programming Landing Page<\/a> top left “Recent Posts” thumbnail images.<\/p>\n

The fix saw us add to the existant “#post-” prefixed hashtag navigation with our “#andabit=-70” “double hashtagging” as mentioned in WordPress Blog Hashtag Navigation Return Onmouseover Tutorial<\/a>. It took us a while to track down where to intervene to achieve this, and we eventually cottoned onto the way that if that RJM Programming Landing Page top left “Recent Posts” iframe container (ie. zero.html<\/b><\/a>) of those thumbnail images could involve URLs suffixed by “#andabit=-70” we would rid the hashtag navigation of that annoyance<\/font> …<\/p>\n

<?php
\n
\n file_put_contents(dirname(__FILE__) . \"\/zero.html<\/b>\",
\n str_replace(\" href='\", ' href=\"',
\n str_replace(\"#andabit=-7x' title='\",\"#andabit=-70' title='\",
\n str_replace(\"0' title='\",\"0#andabit=-7x' title='\",
\n str_replace(\"1' title='\",\"1#andabit=-7x' title='\",
\n str_replace(\"2' title='\",\"2#andabit=-7x' title='\",
\n str_replace(\"3' title='\",\"3#andabit=-7x' title='\",
\n str_replace(\"4' title='\",\"4#andabit=-7x' title='\",
\n str_replace(\"5' title='\",\"5#andabit=-7x' title='\",
\n str_replace(\"6' title='\",\"6#andabit=-7x' title='\",
\n str_replace(\"7' title='\",\"7#andabit=-7x' title='\",
\n str_replace(\"8' title='\",\"8#andabit=-7x' title='\",
\n str_replace(\"9' title='\",\"9#andabit=-7x' title='\",<\/font> str_replace(\"\/wordpress\/\", \"\/ITblog\/\", $htmlis))
\n ))))))))))))<\/font>;
\n<\/code>
\n?><\/p>\n

… reflected by a changed<\/a> recent-posts-2.php<\/a> WordPress “Recent Posts” PHP processing codeset.<\/p>\n

Then that “#andabit=-70” propagates through to a “double hashtagging” scenario you can see with today’s tutorial picture<\/a>.<\/p>\n

WordPress Recent Posts Widget Caching Issues Tutorial<\/p><\/div>\n

The WordPress blog you are reading, with the TwentyTen theme, has a useful “widget” (contained unit of functionality on the webpage that WordPress knows about) called “Recent Posts”, which we’ve had a lot of fun over the years, working with, but “working against”, a tad (because the issue is not exactly mission critical<\/a>, and)<\/font> if you are not careful, are the combination of …<\/p>\n
