Problem Using Data From Forms

Postby pjl2 » 24. August 2012 16:49

First, I am a beginner and I apologize if I have posted this question to the wrong forum. I would appreciate any guidance on finding a more appropriate forum to post to. I also apologize for the length of this post.

I am trying to learn PHP. My goal is to create a site that allows users to enter data into forms so that I can insert that data into a MySql database. But for now I would settle for being able to accept the user data and return a message to the user with PHP.

-I have installed XAMPP for Windows version 1.8.0 using the installer. (But note that I had all the same problem discussed below with the prior version installed).
-The Control Panel Version of XAMPP is v.3.0.12
-The XAMPP control panel says that I am running with administrator rights. I have to hold down shift and control to make this happen when I open XAMPP
-I did not check the services boxes when I installed XAMPP.
-I have Windows 7, but I get the same results (which I describe below) on a Windows XP machine.
-I tried turning off Windows Firewall and my Security Program but it didn't make any difference.

Following is an example that illustrates my problem using a very simple HTML file and a very simple PHP file.

First, the HTML code:

<title=ID Form>
Please fill out the form below:
<!--I just want to enter some integers into the text box-->
<br />
<br />
<form action= "IdForm2.php" method="POST">
Id Number:
<input type="text" name="idvar"/>
<br />
<br />
<input type="submit" value="Submit Form"/>&nbsp;<input type="reset" value="Reset Form"/></p>

Next, the PHP code:


echo 'All work and no play makes Jack a dull boy';
echo '<br><br>';

//I just want to capture the input to the form and then print it out

$Z = $_POST["idvar"];
echo $Z;

echo "<br><br>Rinse and Repeat";


And here is the output that I get:

All work and no play makes Jack a dull boy

Notice: Undefined index: idvar in C:\xampp\htdocs\practice\IdForm2.php on line 8

Rinse and Repeat

I still get this result when I substitute REQUEST for POST in both files.

I did a Google search for prior instances of this problem. I tried a couple of the suggested solutions. One thing that I did was to insert the following code:

if (isset($_POST['idvar'])) {
echo $_POST['idvar'];
} else {
echo 'The variable idvar is not set';

The result is that I get the message stating that the idvar is not set.

I can understand the idea that I can't use a variable that is not set. But that doesn't really help, because my whole purpose for learning this stuff is, as I mentioned, to send user entered data to a database.

Please note that I've just given a simple example of my problem. I get the same undefined index error with other code using forms. So maybe I need to know how to set variables?

I sent this code to my instructor at Big State University, and it runs fine on his machine with an old version of XAMPP installed. By runs fine, I mean that in place of the undefined index error it returns the integer that was submitted in the form. He has no idea why I am having this problem. This is not a degree seeking program and I am free to seek outside help.

I thank you in advance for any guidance you might be able to provide.

Sounds like your php error reporting is set to give NOTICEs. You could change your php.ini error reporting to "error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT"
