  1. I'm used to using $_POST to handle my form data. In chapter 2, Mr Ullman states to use $_REQUEST. I did look up $_REQUEST on php.net and it says that it contains data for $_GET, $_POST, and $_COOKIE. Does that mean I no longer need to bother with $_GET or $_POST and just use $_REQUEST going forward? Sorry for the amateur question. I've done some PHP programming in the past and I'm trying to get back into it (hopefully in the correct way). Thank, James
  2. I probably have some kind of visual/spacial related learning disability. I know that a form sends data to the server where php processes it and outputs it to the browser. Words alone don't always work for me. I have to draw things as if I were trying to explain it to someone else. Some times that helps me to see that my logic simply doesn't compute. Thought I was good to go with arrays... $var = array('dog', 'cat', '2', 'blue'); $var now contains all the values in the array. But, in the book, the syntax (using post) is: $title = $_POST['title']; $name= $_POST['name']; $email= $_POST['em
  3. Hello, This is a beginner's question regarding the "creating errors messages" (pp 381) and the "putting it all together" (pp 415). I'd appreciate if someone could clarify some of the code. In page 318, in the HTML after the paragraph "With that HTML, elem.parentNode refers to the DIV, so appending a new child results in: ..." 1) Shouldn't the span in this HTML have a class = 'error', which was assigned in step 4 ? 2) Why do we need to add a class = 'error' to the span and to the label anyway? I am assuming it is for changing the CSS but I don't see it used in the "Putting it a
  4. Hi there. I'm just having some trouble with the chapter 10 forms 'putting it all together' task. I created the register.js file as guided by the book, which has validation using regular expressions. However, when I load the form in a browser, and try to create some errors by incorrectly filling it in, I just get the generic HTML5 error messages, which say "Please fill out this field". I want the form to validate dynamically using the validateForm() function inside of register.js, not the standard HTML '<required>' validation. How can I make my form use these regular expression
  5. Hello, I have been trying to get my form to validate the radio button which allows my user to agree to the terms and conditions, however, it either prints at the top of the page or not at all. The other prompts print near the form input which is what I would like to happen for the radio button. Following is my code. if (isset($_POST['radio_Agree'])) { $Agree = mysqli_real_escape_string($connect, $_POST['Agree']); } else { $reg_errors['radio'] = 'Please agree to the user Terms and Conditions.'; } <p><label> <input type="r
  6. On the view_users.php page, when you click on the "Edit" link you are redirected to another page using the user_id being passed to next page within the URL. On page 260 we are told of the first method in which uses the hidden input type for forms, how can we apply this method to the "Edit" link hyperlink and what adjustments would need to be made to the view_users.php script to allow this ?
  7. Hello there! The thread referenced (at the bottom) covers how to display two forms on a single page. However . . . In the case referenced, both forms are visible on the page by default, and it is only *after* a submit has been detected that the script detects the form sent, and calls the appropriate code. It seems possible to display only one of the forms based on a user's site visit status. For example, assume a page contains code for both 'Form A' and 'Form B'. What I'm looking for is: 1) When the user visits the page for the first time, 'Form A' is displayed by d
  8. Page 108, version 0.5 The following sentence seems to jump over several points, each of which needs a more detailed explanation. Consequently, I cannot understand this sentence at all: "the form used to both create and edit a record is its own file, and that file can be included by both create.php and update.php (those two files start by changing the headings above the form)." Larry, can you break this down please? Thanks.
  9. Hello, I have been wrestling with textareas in one way or another for quite some time. I would like to add a text area within the Edit User form however, when I update the information from the data base does not appear in the text area. The information does appear in the other fields. This is the last piece of code that I tested: <p><strong>Description:</strong></p> <textarea name="description" rows="5" cols="40" value="' . $row[7] . '" /> </textarea></p> Thanks Marie
  10. I am going through chapter 10 and I have run into a problem with focus and blur events on multiple form elements. I have a function which adds multiple events and handlers to elements. function addPlaceholderHandlers(elem) { 'use strict'; elem.onfocus = setOpacity; elem.onkeydown = removePlaceholder; elem.onblur = addPlaceholder; } // end of addPlaceholderHandlers function Then I run the following code in window.onload window.onload = function() { 'use strict'; var elements = document.getElementById('caseEval').childNodes; for (var i = 0, count = elements.length; i < co
  11. First off, what a well written technical book! Thanks Larry. I'm working on a project that currently uses JavaScript validation. The page will have PHP functionality later, but after reading chapter 6's validation examples, I got to thinking . . . Can I have slicker AJAX style same page validation using PHP? This would put the error messages in the same page after form field completion but before submission. I saw an example elsewhere that essentially points the action to the same page, but it used a lot of "include" scripting. The validation scripting in the book is so simple, yet
  12. Great book. In the form examples throughout the book you recommend combining the form and validation and checking to see if the form has been submitted by using - if ($_SERVER['REQUEST_METHOD'] == 'POST') When I try that I get error messages telling me that the variables haven't been defined yet. That's because the form hasn't been submitted yet! I thought you said that the server function would just be empty if there was nothing to request (ie. before submission)? Am I missing something? Thanks, Arnie
