WordPress Blog Alphabetical Search Primer Tutorial
On a WordPress Blog such as this TwentyTen themed one, there are various mechanisms to search for information. We last talked about this functionality when we finished up a run of blog postings with WordPress Highlighted Search Primer Tutorial which you can link to, but, today, because of the methods used to do our Alphabetical Search it is more apt to show you WordPress Blog Oldest Link Primer Tutorial as shown below.
We changed the Oldest Link inspired PHP source code you could call gotoend.php (changed as per this link) and you will see in it the use of @file_get_contents PHP method where the @ suppresses immediate output, and so is useful, as is this link … thanks.
The place (WordPress Blog TwentyTen theme’s header.php) where the new functionality can be accessed …
formihis = document.getElementById('searchform').innerHTML.replace("</div>", tagselis + catselis + "<input style='display:none;' type='radio' name='stype' value=''><input style='margin-left:-2px;' onclick=\"radiocc('Search');\" type='radio' name='stype' value='Search'>Se<a title='Welcome to alphabetical search functionality ...' href='#searchform' onclick='alphabeticaltest();' onmouseover='getHighlightedSearch();' onmouseout='yehBut();' ontouchstart='getHighlightedSearch();' ontouchend='yehBut();'><font color=red>a</font></a>rc<a title='Welcome to highlighted search functionality ...' href='#searchform' onclick='highlighttest();' onmouseover='getHighlightedSearch();' onmouseout='yehBut();' ontouchstart='getHighlightedSearch();' ontouchend='yehBut();'><font color=orange>h</font></a> <input onclick=\"radiocc('Tag');\" type='radio' name='stype' value='Tag'> <a onclick=\"ovput('Tag');\" title=\"Overlay Tag dropdown ...\" href=\"#tagselis\">Tag</a> <input onclick=\"radiocc('Category');\" type='radio' name='stype' value='Category'> <a onclick=\"ovput('Category');\" title=\"Overlay Category dropdown ...\" href=\"#catselis\">Category</a>" + getalpha + "<select id='seltc' style='display:none;' onchange=\"window.open(this.value,'_blank');\" size='1'><option value=''>Blog Postings below ...</option></select></div>");
… and the PHP function helper method to display results …
<?php echo "\n var getalpha='" . getalphabetical() . "'; \n";
function getalphabetical() {
$aret = "";
if (file_exists("localsearch_" . my_t_d_server_remote_addr() . ".yzy")) {
$aret = file_get_contents("localsearch_" . my_t_d_server_remote_addr() . ".yzy");
if (isset($_GET['orbyder'])) unlink("localsearch_" . my_t_d_server_remote_addr() . ".yzy");
}
return $aret;
}
?>
… and the PHP onload event changes …
function muchlater() {
location.href=document.URL.replace("byorder=", "orbyder=");
}
function precc() { // wopenall= functionality
<?php
if ((isset($_GET['byorder']) || isset($_POST['byorder'])) && (isset($_GET['s']) || isset($_POST['s']))) {
if (isset($_GET['byorder'])) file_put_contents("localsearch_" . my_t_d_server_remote_addr() . ".qry", urldecode($_GET['byorder']));
if (isset($_POST['byorder'])) file_put_contents("localsearch_" . my_t_d_server_remote_addr() . ".qry", urldecode($_POST['byorder']));
echo "\n setTimeout(muchlater, 30000); \n";
} else if (file_exists("localsearch_" . my_t_d_server_remote_addr() . ".qry")) {
unlink("localsearch_" . my_t_d_server_remote_addr() . ".qry");
}
...
?>
… and the new HTML “a” (for the letter “a”) link’s onclick event logic (eventually leading to gotoend.php) …
function alphabeticaltest() {
if (document.getElementById('searchform').action.indexOf("byorder=") == -1) {
if (document.getElementById('searchform').action.indexOf("?") != -1) {
document.getElementById('searchform').action = document.getElementById('searchform').action.replace("/wordpress/", "/wordpress/gotoend.php").replace("/ITblog/", "/wordpress/gotoend.php") + "&max=256&step=1&byorder="; // + encodeURIComponent("ORDER BY post_title ASC ");
} else {
document.getElementById('searchform').action = document.getElementById('searchform').action.replace("/ITblog/", "/wordpress/") + "gotoend.php?max=256&step=1&byorder="; // + encodeURIComponent("ORDER BY post_title ASC ");
}
}
highlighttest();
}
There’s more to do here. We hope it helps you out in some way, or gets you thinking of possibilities.

Wordpress Blog Oldest Link Primer Tutorial
On a WordPress Blog such as this one there are various mechanisms to search for information. Three of the useful ones are to search by Category or Tag or by search words. This, by default, with the default behaviour of the underlying template software of the Twenty Ten theme of this WordPress Blog (the last similar posting being WordPress Blog Submenu Primer Tutorial as shown below), results in Blog Posting links that sort with the most recent postings first. For the most part this is a great decision, but there may be times when a user wants an overview of a big topic and start simply, and work up from there. In such circumstances it makes sense to be able to jump to the oldest, and usually the simplest relevant blog posting, and work from this the other way around.
To enable such functionality involves a bit of work and it is PHP work in our favourite header.php to establish this link and PHP coding to display that “oldest” blog posting as the underlying functionality.
Let’s start with the header.php changes as shown in bold below ( and if there is no course functionality use <body onload=” checkpt(); “> ) …
function checkpt() {
var du=document.URL, ih;
var abit=" <a target='myccor' onclick=" document.getElementById('myccor').style.width='100%'; document.getElementById('myccor').style.height='1200'; " title=' ... welcome to the long hover functionality that shows oldest Blog Posts within a category or tag or normal search' ontouchend=' yehBut(); ' onmouseover=' getOldestPost(); ' ontouchstart=' getOldestPost(); ' onmouseout=' yehBut(); ' href='http://www.rjmprogramming.com.au/wordpress/gotoend.php?";
var h1s;
if (du.indexOf("&paged=") == -1) {
if (du.indexOf("?cat=") != -1 || du.indexOf("?tag=") != -1 || du.indexOf("?s=") != -1) {
if (document.body.innerHTML.indexOf("Older posts") != -1) {
h1s=document.getElementsByTagName("h1");
for (ih=0; ih<h1s.length; ih++) {
if (h1s[ih].className == "page-title") {
if (h1s[ih].innerHTML.indexOf("</span>") != -1) {
abit = abit + location.search.substring(1) + "&max=256&step=256'>(oldest)</a>";
h1s[ih].innerHTML = h1s[ih].innerHTML.replace("</span>", abit + "</span>");
}
}
}
}
}
}
}
function courseCookies() {
checkpt(); // category and tag "oldest"
rptwo(); // Recent Post images
...
}
The new standalone PHP source code you could call gotoend.php and you will see in it the use of @file_get_contents PHP method where the @ suppresses immediate output, and so is useful, as is this link … thanks.
Our contextual help Javascript source code (all in the one place) can be downloaded by wajax.js which changed as per wajax.js for these modifications today.

Wordpress Blog Submenu Primer Tutorial
Lots of websites have a menu of options somewhere near to the top of their landing pages (and the others that follow), to put the navigable parts of the website close to the user’s attention. So you definitely see those major options up above the “fold” (in web design parlance) … and that is great. The other thing people who surf the net (on laptops or desktops, and even though the hover event is not a mobile device thing, the innards of WordPress are helping it work for mobile devices as well) often instinctively do, is to hover over those menus looking to see if there are any submenus coming off those menus, and “gettable toable” without having clicked (or touched) anything yet. These submenus are a win-win for everybody in a lot of ways, because the user may be interested in that functionality, and the web designer can fit more functionality in without overcrowding the look of the web design.
In WordPress, and here we are specifically exemplifying the “Twenty Ten” theme used for this WordPress Blog website, it is a pretty simple procedure to add a submenu (or dropdown menu) …
- Log on as the Administrator using the Meta Menu option “Site Admin” over to the right (of the WordPress “Twenty Ten” theme, anyway) and down the bottom
- Hover over Page icon and pick “Add New Page” option (this type of work is the essence of CMS (Content Management System) … your easier way of “uploading” content to your blog (or forum or whatever))
- Make sure the viewing option tag is set to “HTML”, rather than “Visual” … it’s easier to learn some HTML
- Enter in a good submenu webpage Title … after a bit you get underneath that title a message from WordPress … example for our pictured “Ephemeral” submenu is “Permalink: http://www.rjmprogramming.com.au/wordpress/?page_id=11781”
- At right in Page Attributes section with the Parent dropdown we pick “One Image Site” as the parent menu under which we want to see “Ephemeral” … by the way, the order of this versus the next step is not important …
- Now you have the job of putting in content, which is up to you, but for “Ephemeral” we want to navigate directly to “Ephemeral” webpages with a popup window, so we use blog page code (note how the 11781 is used) like …
<script>
if ((document.URL + "*").indexOf("?page_id=11781*") != -1) {
window.open("http://www.rjmprogramming.com.au/ephemeral", "_blank", "left=100,top=100,width=900,height=800");
}
</script>
- Click or touch the Publish button … and voila, “Ephemeral” appears as a workable submenu (or dropdown menu)
In a way, personally, dropdowns are good for this same basic reason of maximising information for the least amount of space. Whether overcrowding is not your “scene” will determine your feelings on this subject … perhaps you’d like to read about diagonally cut sandwiches while you think about it?
Hope you get something out of our tutorial today, and please note that any self-respecting CMS platform (or other WordPress theme other than “Twenty Ten”) will be able to do this same functionality, as it is commonly asked for by the web design community.
