PHP - Wordpress $wpdb->num_rows() Help

Folks,

Having trouble here. Forgot how you use the COUNT. Not interested in the num_rows due to it being slow compared to COUNT.

I have users table like this:

id|username|sponsor_username

0|barand|requinix

1|phpsane|alison

2|mickey_mouse|requinix

Now, I want to check if a sponsor username exists or not. Such as does the entry "requinix" exists or not in one of the rows in the "sponsor_username" column.

In our example it does twice and so the variable $sponsor_username_count should hold the value "2". Else hold "0".

I get error:

Fatal error: Uncaught mysqli_sql_exception: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '?' at line 1 

 

My code:

	$stmt_1 = mysqli_prepare($conn,"SELECT COUNT(sponsor_username) from users = ?"); 
            mysqli_stmt_bind_param($stmt_1,'s',$sponsor_username_count); 
            mysqli_stmt_execute($stmt_1); 
            
            //Show error if 'users' tbl was not successfully queried". 
            if (!$stmt_1) 
            { 
                echo "ERROR 1: Sorry! Our system is currently experiencing a problem loading this page!"; 
                exit(); 
            } 
            else 
            { 
                mysqli_stmt_bind_result($stmt_1,$sponsor_username_count);     
                mysqli_stmt_fetch($stmt_1); 
                mysqli_stmt_close($stmt_1); 
                
                //Check if Sponsor Username in Url ($_GET) is already registered or not. If not then show "Invalid Url" or Link message. 
                if ($sponsor_username_count < 1) 
                { 
                    echo "<b>Invalid Url or Link!<br> Invalid Sponsor: \"$sponsor_username\"!</b><?php "; 
                    exit(); 
                } 
            } 
	

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.

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!

Hello nice php experts :-)

I've just changed the theme on my wordpress page but wish to add a couple of links to my non-wordpress pages to it.

This is the line of code where I wish to add some more links. I'm going to use the page-link class to format the links but I'm not sure where I would add the extra divs in amongst all of those commas and brackets.

<?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', '' ), 'after' => '</div>' ) ); ?>

Any help is gratefully accepted.

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.

Do you see anything wrong? How can I make this work in my page?   I hope you can help me. Thanks. Regards  

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

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">
