PHP - Wordpress Style Shortcode Function

I have a php tutorial that I followed for creating, inserting, selecting and updating a MySQL database with php.  Everything works fine so I wanted to put it into Wordpress.  I took the code and placed it into the wordpress page and everything worked just fine except the update function. 

Here is the tutorial I used. http://www.phpsimple.net/mysql_insert_record.html  It is also the part I am having trouble with.  I am able to create a record and I am also able to select a record but when I choose "update" the form doesn't load the data.  It will outside the website but not inside wordpress.  I am hoping this is not vague but because of my inexperience I am not sure what else to say.  I will be more than happy to provide any other information you need.

onkeydown="this.style.fontStyle='normal';"

How can I add color: #000; to this?

Thanks,  

Background:
I'm comparing 2 styles of Ajax:
1.) "jquery style"
2.) "ActiveXObject Microsoft.XMLHTTP style"

Question:
Is one better (faster, more cross-browser compliant) than the other?

My experience:
Both seem equally fast. The Microsoft style is a bit longer, but I don't have to load jquery.js to my page!

Code Examples:

Jquery style on my PHP page:

function getInfo(ProductNumber){
$.ajax({
url:'Ajax-PHP-Page.php?ProductNumber='+ProductNumber,
success: function(html) {
document.getElementById("my_div").value = '';
document.getElementById("my_div").value = html;
}
});
}

Microsoft style on my PHP page:

function getInfo(ProductNumber) {
        if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        } else {
            // code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }
        xmlhttp.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                document.getElementById("my_div").value = this.responseText;
            }
        };
    xmlhttp.open("GET","Ajax-PHP-Page.php?ProductNumber="+ProductNumber,true);
  xmlhttp.send();
}

Thank you!!

I am new here I dont know if I am breaching any policy by posting questions.   Are there any Tutorials that can give me input for wordpress basics such as listed here   -  http://codex.wordpress.org/Plugin_API http://codex.wordpre...Class_Reference   I would be indebted if you can help me with that.   Looking Forward. Cheers!

I've been trying to use an example I got off of this forum.
The PHP file works fine as a separate PHP file.
When it's adding into a wp page the following results occur;

Page will access db and display the list of people.
Columns can be sorted by either the id or name.
Existing names can be modified

However;
Can not add new players or delete players

ANY suggestions are appreciated!

Hi Everybody.   Apologies if I've not posted this in the correct forum, but the following line of WordPress code displays the ‘Title’ of my individual blog posts in the Sidebar.   <a href="<?php the_permalink(); ?>"><?php get_the_title() ? the_title() : the_ID(); ?></a>   Can somebody please help me tweak it so it displays both the ‘Title’ and ‘Subtitle’ of each post please? So far I’ve tried adding the ‘Subtitle’ at the end, like this:   <a href="<?php the_permalink(); ?>"><?php get_the_title() ? the_title() : the_ID(); ?><span class="subtitle"><?php the_subtitle(); ?></span></a>   This works in the sense that both the ‘Title’ and ‘Subtitle’ are displayed (both of which are styled in slightly different colours using a separate CSS file), but while the ‘Title’ changes font colour on mouse-hover, the ‘Subtitle’ doesn’t (I’m guessing because I’ve wrapped it in a span class). What I’m really hoping to do is have the ‘Title’ displayed in one colour and the ‘Subtitle’ in a slightly different colour, but for both ‘Title’ and ‘Subtitle’ to change to the same colour when the mouse hovers over either one of them. I’m still building my site, but you can see the Sidebar as it stands, here http://www.retelevise.com.   I don’t know if this is even possible and have not had any feedback on the WordPress support forum, so was really hoping one of the PHP experts here might be able to help me please? Bear in mind I'm a complete PHP novice.   Thanks, SN.

Hi - I'm using the WP Job Boards plugin for Wordpress.  I've been given this code to create a quick search form to place in a widget.  I've tried to paste the code in a sidebar widget and apparently after somebody inputs the keyword and location they should be sent to the results page which will show their results, however, it's not doing that, just showing me a 'page cannot be found' result.   Can anybody help me out with correcting the code?   <form action="<?php esc_attr_e(wpjb_link_to("http://www.littlefox...k/etsgroup/jobs")) ?>" method="GET">

Greetings all,   Been trying to make a plugin in wordpress and ran into an issue with the way wordpress makes use of ajax in the administration menu. The problem is that I completely don't understand it. I've read all the docs on it and even tried messing with a variety of tutorials on the matter to no avail.   What I am trying to do is a simple task outside of wordpress. The form has two select fields, the first field populates the second selection field. While this works fine on a standard html page, trying to do it in wordpress is another story.   Form.php:

<div id="wrapper">
<h1>Second dropdown selection based </h1>
<form action="" method="post">
<p><label>Main Menu :</label>
<select name="main_menu_id" id="main_menu_id">
<option value="">Select</option>
<?php
// Connect to database.
	$connect = mysqli_connect('<!--DB connection info-->");
$q = mysqli_query($connect, "SELECT cfid,cfname FROM categoryfiles ORDER BY cfid");
while($row = mysqli_fetch_array($q)) {
	echo '<option value="' . $row['cfname'] . '">' . $row['cfname'] . '</option>';
}
?>
</select>
</p>
<p><label>Sub Menu:   </label>
<select name="sub_menu_id" id="sub_menu_id"></select>
</p>
</form>
</div>

The script.js

$(function() {
	$("#main_menu_id").bind("change", function() {
		$.ajax({
			type: "GET",
			url: "scripts/get_sub_category.php",
			data: "main_menu_id="+$("#main_menu_id").val(),
			success: function(html) {
				$("#sub_menu_id").html(html);
			}
		});
	});
});

The get_sub_category.php

<?php

	// Connect to database.
	$connect = mysqli_connect('<!--My connection info-->);
							  
	$id = $_GET['main_menu_id'];
	$q = mysqli_query($connect, "SELECT sfid, sfname FROM subjectfiles WHERE sfcategory='" . $id . "' ORDER BY sfname");
	while($row = mysqli_fetch_array($q)) {
		
	echo '<option value="' . $row['sfname'] . '">' . $row['sfname'] . '</option>';
	
	}
?>

Like I said, it works just fine outside of wordpress so really I just need help getting it to work in wordpress. I just don't understand it. Thanks to anyone that takes the time to look this over.   Best Regards, Nightasy

I placed car-dealer-website, a web application from car-dealer-website.org , in a subdirectory on my host mysite.com/car. Wordpress is public_html (mysite.com).

What I am trying to do is embed mysite.com/car in Wordpress. I tried iframe and it is ugly. I looked for a php css options,using a code I found online, it didnt work but I saw hope and think php and css is the solution.

What I am asking for is direction on using php and css to embed in Wordpress. I want to write code no plugins. I hope to learn some php coding. Thank you in advance for your suggestions, tutorials, different methods.

What I remember from my college days is that isset check whether the variable has a value set or not and return true or false value.   However I encountered a code in wordpress -  // Set up the content width value based on the theme's design and stylesheet.

How to work with frameworks ??? from where whould I start learning this topics ??

How do I incorporate wordpress php usage withing standard php? For example, this is typically the template used for the title in wordpress:

Code: [Select]
<?php the_title(); ?>
How would I show that in php, like:

Code: [Select]
$title = the_title(); //this doesn't work by the way
