PHP SQL Form Entry??

How to put into a form so some fields are required and wont let the user enter the data into the database they will need certain fields filled in first. How do you do that with a form? Im using PHP with this form.

example I have set up a form that uses PHP to enter the data into MYSQL and if someone accidently hits enter before they are finished filling out form it submits it and saves the record, I dont want it to be able to do this.

thanks Nick

You'll need to run some validation code on the submitted data first.

eg.

PHP Code:


		
			
if (empty($form['name'])) {

  $err[] = "Name is required";

}

...



//display all the errors



//on submit data if ok, otherwise redisplay with errors



if (count($err)>0) {

  //redisplay

} else {

 //submit

}

PHP Code:


		
			
<?php include("Auth.php"); ?>

 

 <head>

 <title>CWD</title>

 </head>

 <body bgcolor="white">

</body>





 <?

 //------Database Login-----------//

$dbuser = 'root';

$dbhost = 'localhost';

$dbpass = 'pass';

$dbname = 'db';

$dbtable = 'record';



//------ DATABASE CONNECTION --------//

$conn = mysql_connect($dbhost, $dbuser, $dbpass);



//pick the database to use

mysql_select_db($dbname,$conn);



    $thedate = date('Y-m-d', strtotime($_POST[date]));

//create the SQL statement

$sql = "INSERT INTO $dbtable values ('', '$_POST[Counselor]', '$_POST[f_name]',

 '$_POST[l_name]', '$thedate', '$_POST[Meth]', '$_POST[Sex]', '$_POST[Facility]',

 '$_POST[SessType]', '$_POST[NoShow]', '$_POST[BAL]', '$_POST[Length]',

 '$_POST[LOC]', '$_POST[IndSess]', '$_POST[FileLoc]', '$_POST[GroupSess]',

 '$_POST[CD]', '$_POST[Comments]', '$_POST[InsMed]','$_POST[SlidingFee]',

  '$_POST[AmtPaid]', '$_POST[PayAgree]', '$_POST[NonPay]')";



//execute the SQL statement

if (mysql_query($sql, $conn)) {

    echo "<p>Record $_POST[f_name] $_POST[l_name] Added Successfully<br>";

    echo '<a href="new_form.php">Add Another Record</a>';



} else {

    echo "<p>Contact Administrator <strong>tech@tech.org</strong>, Error Saving Record";

}

?>

here is a example of the add record code. say I want to make it so if 'f_name' = Nick then it will not add the record. how do I get this to work, I cant seem to figure it out.

Before you run the SQL, check if $_POST[f_name] == "nick", if it does run the sql. If it doesn't display an error.

Code:

foreach ( ('f_name','l_name','Sex') as $field ) {
  if ( isempty($_POST[$field]) ) {
    $form_err[] = $field;
  }
}

if (isset($form_err)) {
  include(form.php);
  exit;
}

In your form.php, you can have:

Code:

if (isset($form_err)) {
  echo '<h3>There are errors in the form!</h3>';
  foreach ($form_err as $field) {
    echo "$field is not set.<br>";
  }
}

Or something like that... Warning: Off the top of my head, but I hope you get the idea...
