[RESOLVED] Passing Form Variable

[obrienkev]

Hi all,

I have a variable inside a html form... $question_ID

The form uses post method.

Tried to pass the variable using this... $question = $_POST['question_ID'];

Doesn't work though. Any ideas?

Thanks.

I have a variable inside a html form... $question_ID

Exactly what do you mean by that? HTML has no concept of variables.

[obrienkev]

// 1) Perform Question Query
$query = "SELECT question_ID, question_text ".
                  "FROM questions where question_ID = '28'";
$result = mssql_query($query) or die('Select Query Error');

?>

<form action="view.php" name="frm" id="frm" method="post">

<fieldset>

<?php

// 1b) Display Results
while($row = mssql_fetch_array($result))
{
                 // set variable
                 $question_ID = $row['question_ID'];
                 echo '<h2>'.$row['question_text'].'</h2>';
}
....
</form> 

Processing code...

// declare variables
$ans = $_POST['ans'];
$question_ID = $_POST['question_ID'];
$submit = $_POST['submit'];

if(isset($submit))
{
echo '<p>ANS:'.$ans.'</p>';
echo '<p>ID:'.$question_ID.'</p>';
} 

So how do I use that variable once form has been submitted?

You need to create a form element to hold the data. eg;

<form action="foo" method="post">
  <input type="text" name="question_id" value="<?php echo $row['question_ID']; ?>">
</form>

Notice the form element has the name question_id.
