Little coding help for a form

I need this simple form script to require certain fields within the form to be filled out when sending. I'm not sure what needs to be edited. Here's the script I'm using:

$subject = 'Price/Quote Request';                // Subject of email sent to you.
$emailadd = 'email@yahoo.com';        // Your email address. This is where the form information will be sent.
$url = 'http://www.google.com/thanks.html';               // Where to redirect after form is processed.
$req = '1';                                  // Makes all fields required. If set to '1' no field can not be empty. If set to '0' any or all fields can be empty.

// --------------------------Do not edit below this line--------------------------
$text = "Results from form:\n\n";       
$space = '  ';
$line = '
';
foreach ($_POST as $key => $value)
{
	if ($req == '1')
	{
		if ($value == '')
		{echo "$key is empty";die;}
	}
	$j = strlen($key);
		if ($j >= 20)
		{echo "Name of form element $key cannot be longer than 120 characters";die;}
	$j = 20 - $j;
		for ($i = 1; $i <= $j; $i++)
		{$space .= ' ';}
	$value = str_replace('\n', "$line", $value);
	$conc = "{$key}:$space{$value}$line";
	$text .= $conc;
	$space = '  ';
}
mail($emailadd, $subject, $text, 'From: '.$emailadd.'');
echo '<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">';
?>

PHP:

 

So... What doesn't work? What's the error? Where does it go wrong?

 

It works great. But on line 4 from above, you can only choose to have all the fields required or none. I need to specify what fields are required.

 

Post the form, without it we won't be able to tell.

Seems like an ugly script to me, it just dies if something required isn't filled out, without a warning even. I'd get another script.

 

Here's the form. simplescript.php is the script from above. Nothing special...pretty basic -

                  <form name="form1" method="post" action="simplescript.php">
                    <table width="100%" border="0" cellspacing="0" cellpadding="3">
                      <tr> 
                        <td colspan="2"><div align="center"><img src="images/locator_image.gif" width="378" height="60"></div></td>
                      </tr>
                      <tr> 
                        <td width="43%"><div align="right" class="style2">First 
                            and Last Name<font color="#FF0000">*</font>:</div></td>
                        <td width="57%"><div align="left"> 
                            <input type="text" name="Name" size="30">

                          </div></td>
                      </tr>
                      <tr> 
                        <td><div align="right" class="style2">Home/Cell/Work Phone<font color="#FF0000">*</font>:</div></td>
                        <td><div align="left"> 
                            <input type="text" name="Phone" size="30">
                          </div></td>
                      </tr>

                      <tr> 
                        <td><div align="right" class="style2">E-mail Address<font color="#FF0000">*</font>:</div></td>
                        <td><div align="left"> 
                            <input type="text" name="Email" size="30">
                          </div></td>
                      </tr>
                      <tr> 
                        <td><div align="right" class="style2">Approximate Moving 
                            Date<font color="#FF0000">*</font>:</div></td>

                        <td><div align="left"> 
                            <input type="text" name="Moving_Date" size="30">
                          </div></td>
                      </tr>
                      <tr> 
                        <td><div align="right" class="style2">Price Range<font color="#FF0000">*</font>:</div></td>
                        <td><div align="left">
                            <input type="text" name="Price_Range" size="30">

                          </div></td>
                      </tr>
                      <tr> 
                        <td colspan="2"><div align="center"><font color="#FF0000" size="1">* Required</font></div></td>
                      </tr>
                      <tr> 
                        <td colspan="2"><div align="center"> 
                            <input type="submit" name="Submit" value="Submit for Apartments in Houston">
                          </div></td>
                      </tr>

                    </table>
                  </form>

PHP:

 

Change:

$req = '1';

PHP:

To:

$req_array = array('Name' => 1, 'Phone' => 1, 'Email' => 1, 'Moving_Date' => 1, 'Price_Range' => 1); //Change 1 to 0 if not required

PHP:

Then change line 13 and down:

if ($req == '1')
    {
        if ($value == '')
        {echo "$key is empty";die;}
    }

PHP:

To:

if ($req_array($value) == '1')
    {
        if ($value == '')
        {echo "$key is empty";die;}
    }

PHP:

OTTOMH that should do it.

 

ah, sweet! Thanks! I'll give that a try.
