jeffreader Posted February 18, 2017 Share Posted February 18, 2017 I have an iMac OS 10.12.3 and FireFox browser 51.0.1. I also use a CodeReader 2.2.2. I also run on an XAMPP 7.0.13-1 which I turned on the "MySQL Database and Apache Web Server" only. Now, I am learning from your book as a beginner. HTML Forms and PHP on Chapter 3 and page 64. I submitted my feedback_form.php on the browser - page 64 and my result showed up like this. How can I fix this problem? Notice: Undefined index: title in /Applications/XAMPP/xamppfiles/htdocs/practice /handle_form.php on line 16 Notice: Undefined index: name in /Applications/XAMPP/xamppfiles/htdocs/practice /handle_form.php on line 17 Notice: Undefined index: response in /Applications/XAMPP/xamppfiles/htdocs/practice /handle_form.php on line 18 Notice: Undefined index: comments in /Applications/XAMPP/xamppfiles/htdocs/practice /handle_form.php on line 19 Thank you, , for your comments.You stated that you found this example to be '' and added: Link to comment Share on other sites More sharing options...
jeffreader Posted February 23, 2017 Author Share Posted February 23, 2017 On page 59, this is exact what I wrote down on my CodeRunner and saved the "handle_form.php." This is what happened above the previous comment that has the errors. I also wrote down the exact code on feedback.html that came out fine which is on page 56. I don't understand the errors for this handle_form.php. Larry, Can you help me with that problem? This is "handle_form.php": <!DOCTYPE html><html lang="en"><head> <meta charest="utf-8"> <title>Feedback Form</title></head><body> <?php // Script 3.3 handle_form.php // This page receives the data from feedback.html. // It will receive: title, name, email, response, comments, and submit in $_POST. // Create shorthand versions of the variables: $title = $_POST['title']; $name = $_POST['name']; $response = $_POST['response']; $comments = $_POST['comments']; // Print the received data: print "<p>Thank you, $title $name, for your comments.</p> <p>You stated that you found this example to be '$response' and added:<br>$comments</p>"; ?> </body></html> ------------------------------------------------------- ------------------------------------------------------- This is a "feedback.html": <!DOCTYPE html><html lang="en"><head> <meta charest="utf-8"> <title>Feedback Form</title></head><body> <!-- Script 3.2 - feedback.html --> <div><p>Please complete this form to submit your feedback:</p> <form action="handle_form.php" method="post"> <p>Name: <select name="title" required> <option value="Mr.">Mr.</option> <option value="Mrs.">Mrs.</option> <option value="Ms.">Ms.</option> </select> <input type="text" name="name" size="20" required></p> <p>Email Address: <input type="email" name="email" size="20" required></p> <p>Response: This is... <input type="radio" name="response" value="excellent" required> excellent <input type="radio" name="response" value="okay"> okay <input type="radio" name="response" value="boring"> boring</p> <p>Comments: <textarea name="comments" row="3" cols="30" required></textarea></p> <input type="submit" name="submit" value="Send My Feedback"> </form> </div></body></html> Link to comment Share on other sites More sharing options...
Larry Posted February 24, 2017 Share Posted February 24, 2017 Just to confirm, are you actually filling values into the form? Link to comment Share on other sites More sharing options...
Jaepee Posted February 24, 2017 Share Posted February 24, 2017 Notice: Undefined index This notice appears when you (or your PHP script) atempts to access an undefined index of an array. You can avoid these notices by, checking with your code to see if the index exists before you access it. For this you can use isset() or array_key_exists() Note that theses notices appear often when working with $_POST, $_GET or $_SESSION. It is good practice to make sure a variable exists and is set before you use it. Happy Coding! jp Link to comment Share on other sites More sharing options...
jeffreader Posted March 11, 2017 Author Share Posted March 11, 2017 I finally signed a hosting service in order for you to see my two images that I wanted to show you. Here is the link: http://brioservices.com (only two images on this link) The second picture that I don't understand why it asked me to download the handle_form.php. My book does not say about the download. I do not feel that I want to skip the chapter until it solves this problem first. I am sorry I have not read about the isset() and array_key_exits() yet because I am in the chapter 3 this time. I am currently use my CodeRunner to edit it. Any idea how to prevent this asking for the download? http://brioservices.com Link to comment Share on other sites More sharing options...
Larry Posted March 13, 2017 Share Posted March 13, 2017 You're being asked to download the form because you're not running the HTML form page through a URL. You need to load that page via http://something. Link to comment Share on other sites More sharing options...
jeffreader Posted March 14, 2017 Author Share Posted March 14, 2017 Hello Larry, First of all, I have an issue with two directories on my iMac. I created two folders which are "practice" and "My program files." Do you think that the XAMPP 7.0.13-1 confused with these directories? ...My XAMPP runs MySQL Database and Apaches Web Server but not ProFTPD. My friend from out of state told me that I put "practice" files in the Applications/XAMPP/xamppfiles/htdocs/practice. Is that normal? I put all original files in "My program files" folder because of your scripts such as Script 1.5 to Script 3.4... that I do not want them to be override. I do not have your email address but remember that I bought your book. Link to comment Share on other sites More sharing options...
Larry Posted March 14, 2017 Share Posted March 14, 2017 I don't think XAMPP is confused. There's a setting in XAMPP that says where the web root directory is, which is probably /Applications/XAMPP/xamppfiles/htdocs. The URL http://localhost should point there. So if you put something in /Applications/XAMPP/xamppfiles/htdocs/practice, that URL would be http://localhost/practice It's absolutely fine to use subfolders, but don't use anything in the name of the subfolders that couldn't go in a URL, like spaces.

jeffreader Posted March 15, 2017 Author Share Posted March 15, 2017 On page 61 and 64. I created two files for Script 3.3 and 3.4. My original result showed an error for Script 3.3 - The error stated: Undefined index... /handle_form.php on line 17. It is almost perfect result. So, I created the Script 3.4 below of two images - "2nd result with deleted code lines." The Script 3.4 looks perfect because I removed two code lines that eliminated the errors. However, I realized that the ini_set is supposed to show me the problem first. What is the problem or what did I missed in the coding? Please look at the two codings: http://brioservices.com/index2.html Link to comment Share on other sites More sharing options...

jeffreader Posted March 18, 2017 Author Share Posted March 18, 2017 Oh well. I forgot to add " = " between name and "comments on line 28 (feedback.html) which is on page 51. This is how I get so mad because it does not tell me the specific error. I wasted my time to figure it out. I looked up my phpinfo.php... "display_errors => STDOUT => STDOUT" I have no idea what does that mean. I thought that it would say on or off (See page 63). ---- I am currently on page 70 - it does not show up a bold name. It showed up a normal text. What did I missed probably on line 22? Also, I am curious about the Greeting! Is it supposed to show up another bold Greeting! ? <!DOCTYPE html><html lang="en"> <head> <meta charset="UTF-8"> <title>Greetings!</title> <style type="text/css"> .bold { font-weight: bolder; } </style> </head> <body> <?php // Script 3.7 - hello.php ini_set('display_errors', 1); // Let me learn my mistakes! error_reporting(E_ALL); // Show all possible problems! // This page should receive a name value in the URL. // Say "Hello": $name = $_GET['name']; print "<p>Hello, <span class=\"bold\">$name</span>!</p>"; ?> </body></html> Link to comment Share on other sites More sharing options...
jeffreader Posted March 19, 2017 Author Share Posted March 19, 2017 Also, how can I turn on the display_errors on my iMac (macOS Sierra)? If I want to turn it off, what should I do next? Does it has to do with the Terminal? I am not familiar with the Terminal app. Link to comment Share on other sites More sharing options...
Larry Posted March 20, 2017 Share Posted March 20, 2017 STDOUT stands for "Standard Output": https://en.wikipedia.org/wiki/Standard_streams#Standard_output_.28stdout.29 If you look in the appendix, you'll see how to configure your PHP installation. It does require the Terminal, so you may want to also look online for the basics of using the Teriminal on Macs. As for the bold issue, I'd start by checking the source code of the page in the browser. It looks right to me as is (i.e., that it should be in bold).

Larry Posted April 3, 2017 Share Posted April 3, 2017 Just to confirm, you are actually filling out the form--providing all those values--and yet you still see those error messages? Link to comment Share on other sites More sharing options...
jeffreader Posted April 3, 2017 Author Share Posted April 3, 2017 No, I typed it on my Firefox browser - http://localhost/practice/handle_post.php"as long as XAMPP is running. Then I entered this address and came up the statement errors on the browser - without seeing the form. On Script 5.1 was fine which is on page 94 because I see the form on my browser. Also on page 99, it was fine for both A and B in the pictures. On page 102, this is a problem. Maybe, there are two problems on line 17 and 20. (I saved the handle_post file for PHP and posting file for HTML.) Link to comment Share on other sites More sharing options...
Larry Posted April 3, 2017 Share Posted April 3, 2017 Okay, that's totally fine and to be expected if you run the handle_post.php script directly (as opposed to using the form). If you keep reading, you'll learn more about what's going on. Link to comment Share on other sites More sharing options...

jeffreader Posted April 13, 2017 Author Share Posted April 13, 2017 Could you elaborate on what you're lost on and what you'd like me to rephrase? I can't fresh my mind. The var1 to var3 have different and also empty(). It is same thing for isset(). Actually, I thought that there is only one var that something to clear out for one example but it has three examples (i.e. var1, var2, var3). I am not sure why do I have to know about them.

Larry Posted April 19, 2017 Share Posted April 19, 2017 So the examples are just trying to demonstrate what it means to be "set", "empty", and "numeric" and uses a couple of different values--represented by variables--to do so. Link to comment Share on other sites More sharing options...
