PHP Themed Supervision Fifth Genericization Tutorial<\/p><\/div>\n

More than a week ago, now, we started off with HTML\/Javascript Themed Supervision Primer Tutorial<\/a> having a pretty hardcoded feel to it, as a web application gathering together other web applications under the concept of “ESL Ideas”. Then four days ago we started on our “genericization” drive involving the introduction of external Javascript and the address bar URL GET parameters, as dynamic controllers of web application content.<\/p>\n

Then three days ago on the continuation of our “genericization” drive we introduced some document.write<\/a>(prompt<\/a>([wording],[default]));<\/i> inspired web interactive functionality.<\/p>\n

Then two days ago on the continuation of our “genericization” drive, we were still only involving client side HTML and Javascript and CSS, and we introduced some HTML form<\/a><\/i> inspired web interactive functionality, using interim HTML input type=button click functionality to send messages internally back to the same HTML source code living within the parent web page within a child HTML iframe element, and introducing new callback functionality to be able to turn its parent’s cell content into the type of content “looking” (but “actually” slightly different) to what we’d been getting used to in earlier incarnations of the HTML and Javascript and CSS for this series of “ESL Ideas” blog postings.<\/p>\n

Yesterday we embarked on our PHP server side journey aspects to the genericization process when we presented PHP Themed Supervision Fourth Genericization Tutorial<\/a> as shown below, highlighting the great features of the HTML form method=post posting (perhaps large amounts of) data to a serverside language, ours here at our Apache web server being PHP.<\/p>\n

And so we come to today, and we’re showing PHP’s talent for dynamic modular development. Let me explain. We identified the biggest bugbear with the “form mode” information gathering is the filling in of URLs, so perhaps it would be good to help out this process, at least with regard to WordPress Blog Posting URLs, and lobbed onto the thought of channelling what tutorial_options.php<\/a> does in Landing Page Mobile Phone Crontab Curl Tutorial<\/a>. It gleans information about RJM Programming Blog Posting URLs from corresponding MySql databases, and some crontab\/curl dynamic “cc” magic turns this into some useful dropdown functionality on our Landing Page’s Iframe<\/a>. Why reinvent the wheel? Why not take most of that good functionality and “appropriate” it into our current work. For instance, a few lines of PHP code like …<\/p>\n


\n$selbit=\"\";
\n $lpage=@file_get_contents(\"http:\/\/www.rjmprogramming.com.au\/Welcome.html\");
\n $lbits=explode(\"<select\", str_replace(\"<\/select\", \"<select\", $lpage));
\n if (sizeof($lbits) > 1) {
\n $selbit=\"  <select\" . $lbits[sizeof($lbits) - 2<\/b>] . \"<\/select>\";
\n }
\n<\/code><\/p>\n

… can have an up to date and very useful dropdown (the last<\/b> such dropdown in whatever HTML you use as your starting point) of Blog Postings placed into our “ESL Ideas” “form interactive” and “post interactive” scenarios to aid with collecting some RJM Programming WordPress Blog Posting URL details via the use of the PHP $selbit<\/i> variable above. Does it feel a bit like “local home grown” data scraping? The rest of what we do today is to add three new buttons for each of the 8=(9 – 1) relevant cell “web application” members to map onto them, optionally, what was selected in this dropdown, placed the once up the top near the theme HTML input type=text element. On clicking a relevant such button the dropdown’s URLs and label get populated into the relevant fields, saving heaps of time, and avoiding some wrong keystrokes, we hope.<\/p>\n

Recap time … hats to the left of me, jokers to the right<\/a><\/font>. Take a skeg at our newer PHP source code you could call middle_interest.php<\/a> (changed from before as per this link<\/a>). Once again, have a look at our HTML and Javascript and CSS programming source code you could call middle_interest.html<\/a> (changed from before as per this link<\/a>) supervising the external Javascript you could call middle_interest.js<\/a> (unchanged from yesterday) and\/or try a …<\/p>\n
