Chapter 5 Page 118 - Please Select A Category!

Recommended Posts

I'm having problems figuring out how to fix my "category not found error" on my add_page.php. This is a repost I believe of the same error Posted 25 February 2016 - 9:39 PM. 

 

Here is book code:

8. Validate the category:
if (filter_var($_POST[‘category’], FILTER_VALIDATE_INT, array(‘min_range’ => 1))) {
$cat = $_POST[‘category’];
} else { // No category selected.
$add_page_errors[‘category’] = ‘Please select a category!’;
}
Each HTML page is in a single category. That association is made by
attaching to each page record a foreign key to the proper value in the
categories table. To confirm that the category value is an integer greater
than, or equal to, 1, I’m again turning to PHP’s Filter extension.

 

----------------------------------------------------------------------------------------------------------------------

The problem I'm having is following the logic of selecting a category in the pulldown on the page, going to the categories table, checking if category is a number between 1-5, going to the pages table, inserting a row with the categories_id number assigned.

 

To much going on. Categories, Category, Categories_id. Can't follow logic. Seems like if I rename something in the database it will work. My guess is this is a foreign key issue. I'm a student, how would I know. Category in categories table is trying to match to Categories_id in Pages table? Heck, I don't know.

 

Note: I got the code to work locally if I rem out the $cat parameter in a few places but I'd like the code to work the way it was designed!

 

Here is my MySQL database info. Note that for the pages table below I've manually added data for the five different categories (and it shows up fine in the page). I just can't add a page (row) through the add_page.php interface!

 

Here is a dump of my Categories and Pages tables:

Well, it's 3 days later and still no idea why your code isn't working. It's looking for an index called category when there isn't one. 

 

8.      Validate the category:

if (filter_var($_POST[‘category'], FILTER_VALIDATE_INT,

-array('min_range' => 1))) {

$cat = $_POST[‘category'];

} else { // No category selected.

$add_page_errors['category'] = 'Please select a category!';

}

What is the value of $_POST['category'] when the form is submitted (assuming at least one category has been selected)? And what is the HTML source of the category aspect of the HTML form?

Hi Larry!

Sorry, no idea what the value for category is. I'm a student. I'm not running an ide where I can trace stuff like in C++, just a text editor. Not sure how to run a trace for string or array variables in PHP. I tried to echo and print out the value of category but since it's an array value I get a you can't print out a string value from an array. Looked here also: http://stackoverflow.com/questions/4383914/how-to-get-single-value-from-php-array but not sure if that would work or what to plug in.

 

 

Any suggestion is helpful. As I said before if I remove the category validation stuff, and $cat, the page posts with a category id of 0 in the database (using phpMyAdmin to look), but it posts a row!

 

Not sure how the add_page.php select pulldown to select a category is suppose to interact with the table with the categories or pages tables. Not explained in the book. The database categories table lists the 5 categories and their related ids. 

 

 

Thanks, Joe

 

 

 

I've been playing with the add_page.php code.  Here is what I currently have:

<?php

// This page is used by an administrator to create a specific page of HTML content.
// This script is created in Chapter 5.

// Require the configuration before any PHP code as the configuration controls error reporting:
require('./includes/config.inc.php');

// If the user isn't logged in as an administrator, redirect them:
redirect_invalid_user('user_admin');

// Require the database connection:
require(MYSQL);

// Include the header file:
$page_title = 'Add a Site Content Page';
include('./includes/header.html');

// For storing errors:
$add_page_errors = array();

// Check for a form submission:
if ($_SERVER['REQUEST_METHOD'] === 'POST') {	
	
	// Check for a title:
	if (!empty($_POST['title'])) {
		$t = escape_data(strip_tags($_POST['title']), $dbc);
	} else {
		$add_page_errors['title'] = 'Please enter the title!';
	}
	
	/*
	// rem the lines below to get rid of category error.
	// Check for a category:
	if (filter_var($_POST['category'], FILTER_VALIDATE_INT, array('min_range' => 1))) {
		$cat = $_POST['category'];
	} else { // No category selected.
		$add_page_errors['category'] = 'Please select a category!';
	}

	*/
	
	// Check for a category (Ch 5 Pg 118):
	
	if (filter_var($_POST['category'], FILTER_VALIDATE_INT, array('min_range' => 1))) {
		$cat = $_POST['category'];
	} else { // No category selected.
		$add_page_errors['category'] = 'Please select a category!';
	}
	
	
	/*

	$cat = $_GET['category'];
		} else { // No category selected.
		$add_page_errors['category'] = 'Please select a category!';
	}
	*/
	
	/* Testing!!!!
	if (isset($_POST["category"]))
{
  $user = $_POST["category"];
  echo $user;
  echo " is your field name category";
} 
else 
{
  $user = null;
  echo "no field exists for category";
}
	*/
	
	// Check for a description:
	if (!empty($_POST['description'])) {
		$d = escape_data(strip_tags($_POST['description']), $dbc);
	} else {
		$add_page_errors['description'] = 'Please enter the description!';
	}
		
	// Check for the content:
	if (!empty($_POST['content'])) {
		$allowed = '<div><p><span><br><a><img><h1><h2><h3><h4><ul><ol><li><blockquote>';
		$c = escape_data(strip_tags($_POST['content'], $allowed), $dbc);
	} else {
		$add_page_errors['content'] = 'Please enter the content!';
	}
		
	if (empty($add_page_errors)) { // If everything's OK.

		// Add the page to the database:
		$q = "INSERT INTO pages (category, title, description, content) VALUES ($cat, '$t', '$d', '$c')";
		
		// TEST WITH NO CATEGORIES_ID - WORKS
		// $q = "INSERT INTO pages (title, description, content) VALUES ('$t', '$d', '$c')";
		
		$r = mysqli_query($dbc, $q);

Here is a dump of my sql.sql table. I've been messing with the categories and pages tables so the index and colums for categories, categories_id, category, are probably a little different than the book.

Ah! I see what the problem is. You're running both the regular add_page.php and the code that has the bonus material from Chapter 12. If you uncomment out lines 99-101 and comment out or remove lines 107-108 to make the code look like it does in Part 2 of the book, you should be fine. Sorry for the confusion!

Yea! You nailed it on the first try. Thanks for spending time looking over my code! I've been taking classes at the community college for 4 years (part time) while working full time and this is the first class I've had problems with. Thanks for the fix!!!!!!!

 

Category was trying to use array to pick up multiple categories and was dying. So, for anyone else here is what I did to go back to picking a single category and have the add_page.php work again:

 

Comment out the following lines in add_page.php to stop category trying to use an array:

echo '"><label for="category" class="control-label">Category</label>
<select name="category[]" class="form-control" multiple size="5">';

Comment in the following line (right above it) to have category go back to a single select:

echo '"><label for="category" class="control-label">Category</label>
<select name="category" class="form-control">
<option>Select One</option>';

Excellent. Glad it's working for you and that you understand why. Apologies again for the confusion (I spent some time trying to figure out how to best present two different versions of the script; perhaps inline comments were not sufficient). Let me know if you have any other questions or problems!

Hi everyone,

 

I created a php page which contains forms textfields and drop-down boxes. I can see my page when I try on localhost. But after I upload the page via ftp and call my site, I only see "51" on the page. Can anyone tell me why?

 

Thanks

Unfortunately you'll need to provide more information than that, like the code itself that you're using. Also if there's a URL where we can see this in action, that'd be helpful.
