Open Browser in Bash

Here’s a nice little command to open a browser from Bash.

#!/bin/bash
open https://domain.com/path/to/web/page/index.html

You can use this command to open a web page from your script.

Ajax Live Search

Just implemented an Ajax live search on a website.

Here’s the search page. Results are displayed in div output.

<script src="https://code.jquery.com/jquery-3.4.1.js"></script>
<script type="text/javascript">
$(document).ready(function(){
    $("#search").keyup(function(){
        var query = $(this).val();
        if (query != "") {
        $.ajax({
            url: 'links-ajax.php',
            method: 'POST',
            data: {query:query},
            success: function(data){
            $('#output').html(data);
            $('#output').css('display', 'block');
            $("#output a").on("click", function(){
                $("#output").val($(this).html());
            });
            $("#search").focusout(function(){
                window.setTimeout(function() {
                $('#output').css('display', 'none');
                }, 500);
            });
            $("#search").focusin(function(){
                $('#output').css('display', 'block');
            });
            }
        });
        } else {
        $('#output').css('display', 'none');
    }
    });
});
</script>
 
<div class="form-row">
    <div class="col">
        <input type="text" name="search" id="search" autocomplete="off" placeholder="Search here...." class="form-control form-control-success">
    </div>
</div>
<div id="output"></div>

Here’s the links-ajax.php which display the search results with links.

<?php
$servername='localhost';
$username='';
$password='';
$dbname = "";
$conn=mysqli_connect($servername,$username,$password,"$dbname");
if(!$conn) { die('Could not Connect MySql Server:' .mysql_error()); }
if (isset($_POST['query'])) {
    $query = <<<"SQL
                 SELECT * FROM links WHERE `name` LIKE '%{$_POST['query']}%' 
                 OR `url` LIKE '%{$_POST['query']}%' 
                 OR `tag` LIKE '%{$_POST['query']}%' 
                 ORDER BY name ASC, url ASC"
             SQL;
    $result = mysqli_query($conn, $query);
    if (mysqli_num_rows($result) > 0) {
        while ($user = mysqli_fetch_array($result)) {
            echo "<a target='_blank' rel="noopener">".$user['name']."</a><br/>";
        }
    } else {
        echo "<p style='color:red'>No results found...</p>";
    }
}
?>

I couldn’t get the links working, until I added the 500ms of timeout in .focusout.

Markdown Language

Style your text using markdown. If you use GitHub, markdown will come in handy.

Examples:

# This is an <h1> tag
## This is an <h2> tag
###### This is an <h6> tag

Here are more markdown examples.

Gutenberg Youtube Embed

The Gutenberg Youtube embed lacks a few things. The alignment doesn’t seem to be working, at least in the theme I’m using. I’m using Generate-Pro, a Genesis child theme. By default, it’s left-aligned. I have to add this div to make it centered.

<div style="text-align:center">
</div>

If you want right aligned, use this div.

<div style="text-align:right">
</div>

TLK.IO Embed

tlk.io is a simple chat page that you can embed on your site. If all you are seeing is a blank screen, I may have a fix for it. I don’t think it’s documented anywhere. I did not see it on tlk.io’s website. Here’s the code that they want you to embed. Of course, you have to use your own data-channel instead of the default “hey.”

<div id="tlkio" data-channel="hey" style="width:100%;height:400px;"></div>
<script async="" src="http://tlk.io/embed.js" type="text/javascript"></script>

The above code will not work if your site is secured via SSL. You’ll need to change the embed.js reference to https. In this case, it would be something like this. 

<div id="tlkio" data-channel="hey" style="width:100%;height:400px;"></div>
<script async="" src="https://tlk.io/embed.js" type="text/javascript"></script>

The code will work in WordPress as well.
