// Vendor string $vendor_string .= <<<EOVS $header_string <tr> <td colspan="4"><br> <br> <form method="POST" name="insert_url" action="week6.php?view=vendorq"> Select the vendor of your choice: <SELECT NAME="vendor2"> $option_block; </SELECT> <input type="hidden" name="vendor_select" value="v"> <INPUT TYPE="Submit" NAME="Submit" Value="Submit"> </FORM> EOVS; -----Original Message----- From: Kevin Stone [mailto:[EMAIL PROTECTED]] Sent: Friday, February 14, 2003 6:41 PM To: Php-General Subject: Re: [PHP] function problem Exactly where does $option_block get put into $string? -Kevin ----- Original Message ----- From: "Peter Gumbrell" <[EMAIL PROTECTED]> To: "Php-General" <[EMAIL PROTECTED]> Sent: Friday, February 14, 2003 4:11 PM Subject: [PHP] function problem > I have a function below which populates a select list, based on the query > string and the field name.
