Simple form validation

[jaArch]

I'm having trouble with this form. I can't seem to figure out the rest of what is required I have already done most of it...I'm just stuck on these parts:

 

Province Select : (AutoGeneration, Multiple Select, Memory)

 

    AutoGeneration using Provinces Array: The Province Select box is generated by PHP using this array: provinces.txt Cut and paste this array into your own code.

    Multiple Selections: Note that the province select box permits multiple values to be selected. View the HTML source to see the configuration details. Also note how $_POST delivers these multiple values as an array.

    Select Box Memory: The Province select box retains the user choices after a POST. For each province selected by the user, your code will generate the "selected" attribute in the <options> tag for that province. View the HTML source of the working solution to see how this works.

 

Status CheckBoxes (Multiple Select, Memory)

 

    Multiple Selections: Note that these checkboxes have been configured in the HTML to permit multiple selections. Also note that $_POST delivers these multiple selection values in an array.

    Status Box Memory:The Status Box retains the user choices after a POST. Your code will need to generate the "checked" attribute in the <input> tag for each item selected.

    Do not generate the checkboxes with an array.

 

Location Radio button:

 

    Do not generate the radio buttons with an array.

    The Location radio button retains the user choice after a POST.

 

Validation Success Message:

 

    Where does it go - The final success message is placed within the <div class="success"></div> tags at the top of the HTML.

    Use a Loop: Generate the success message with a single array loop that reads the $_POST array and prints out the success message as an ordered list.

    Form Variables List

        Un-Ordered List - The form variables are displayed in an unordered list . CSS removes the bullet.

        Names Capitolised - The names of the form variables are capitolised ( use strtoupper() function ) .

        Handle Empty Values - Print "---None supplied---" if the variable is empty.

        Province Long Names - Print the long names of the provinces selected as comma separated string

        Status Choices - Print the status choices as a comma separated string.

 

Functions I need to use:

 

    empty() - is the string empty. Unfortunately, a "0" value counts as an empty string.

    strlen() - returns the number of characters in a string.

    is_numeric() - is the string a number

    count() - how many rows in an array

    is_array() - is the variable an array

    isset() - does the variable or member of array exist

    in_array() -does this string exist in this array

    strtoupper() - convert string to upper case.

    join() - you'll want this one too. Converts an array of strings into a string with a delimiter.

    error_reporting(E_ALL ^ (E_NOTICE | E_WARNING)); - suppresses warning messages in your code. Place at top.

    foreach ($_POST as $KEY => $VAL) {} - walk through the $_POST array (or any array)

 

My code:

					"qc"=>"Quebec",
					"on"=>"Ontario",

  if ($_SERVER['REQUEST_METHOD'] == 'GET')
  {
  $dimwelcomeMsg = TRUE;
  }
  
  if ($_SERVER['REQUEST_METHOD'] == 'POST')
  {
  if ($_POST['uname'] == ''){

	$unameInError = true;
  }
  if (empty($_POST['year']) == TRUE){
	  $errMsgs['year'] = "Year must not be blank!!";
  }
  if (count($errMsg) > 0 ):
  	$dispErrorMsg = TRUE;
	else:

	foreach ($_POST as $key => $val):
	$key = strtoupper($key);
	$successMsg[$key] = $val;
	endforeach;

	$dispSuccessMsg = TRUE;

Bump...can anyone help?

[Pikachu2000]

We aren't here to do homework for people. What specifically are you having a problem with?

[jaArch]

I'm having trouble getting the values in the $PROVINCES array into the select box and I'm also having trouble getting the error messages to display whenever the user has left the field empty or whenever the user has entered invalid data.

    error_reporting(E_ALL ^ (E_NOTICE | E_WARNING)); - suppresses warning messages in your code. Place at top.

 

^^^ Whoever suggested suppressing error messages, gave you some bad advice, especially when trying to learn php, develop php code, and debug php code. Hiding those types of error messages will also hide the type of problems people make when first starting out learning a programming language. Not only will your code not work, but you won't get any error messages from php alerting your to where it found detectable problems in your code.

 

As stated in your other thread for this same code/problem, I found the incorrectly named variable that is preventing your validation error messages from being displayed through trying your code and getting an undefined variable message from the code that was referencing a variable that didn't exist.

 

I guess I repeat it here, since you didn't read, understand, or follow the advice given in your existing thread -

You should be developing and debugging your code on a system with error_reporting set to E_ALL and display_errors set to ON so that php will help you by reporting and displaying all the errors it detects. You will save a TON of time.

[jaArch]

I just think PHP is too hard for me and I've read what you've suggested...I just can't figure out how to do it

[jaArch]

The problem is that I just don't understand how to do this:

Can you explain how I can do it?

[jaArch]

Alright...I figured out the e-reporting thing. Thanks for the tip

[jaArch]

What does this mean and how do I fix it?

 

Notice: Undefined variable: displaySuccessMsg in /home/students/000136921/public_html/10065/php/3/formval.php on line 111

[awjudd]

By defining that variable? 

$displaySuccessMsg = NULL;

 

Or by checking if it is set before using it?

if(isset($displaySuccessMsg)
{
    echo $displaySuccessMsg;
}
