How do I dynamically changed a form result layout using php

I have a form using php. Depending on one of the fields entered, I want to add extra info on the form result. I am having trouble with the syntax. I only want the code below printed out in the form result when a the address field has "ny" or "nyc" or "manhattan" entered in it

      <tr><td> This is to certify that I am an authorized officer of</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtCompanyName'] . "</td></tr>


                        <tr><td> Date:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtSignatureDate'] . "</td></tr>
                        <tr><td> Name:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtCompanyOfficer'] . "</td></tr>
                        <tr><td> Title:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtCompanyOfficerTitle'] . "</td></tr><br />
<tr><td> Signature:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtSignature'] . "</td></tr>
                         <tr><td> Lien Amount $:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtExactOwed'] . "</td></tr>

                         <tr><td colspan=\"3\">Block:</td></tr>
                         <tr><td colspan=\"3\">Lot:</td></tr>

You have not shown us enough of the code to understand where to find ny or nyc, etc. However the usual design pattern is to use an if() statement.

Ray Paseur

Also, you might want to consider simplifying your programming life by learning about HEREDOC notation - it will make the syntax much easier to read.
http://www.php.net/manual/en/language.types.string.php

Example...

$str = <<<END_OF_STRING
<td>$var</td>
END_OF_STRING;

No concatenation, no quotes, just variable substitution on $var -- really easy to get right!

Try

if (preg_match("/(ny|nyc|manhattan)/i", $_POST['addressfieldname'])){
	echo "HTML goes here";
}

Thanks for yuour quiclk responeses. This is the filed I need to check for ny, nyc and manhattan. I
if ($_POST['ctl00$ContentPlaceHolder1$txtCompanyCity'] == "" )

If this field has any of those values, then I want to diplay the lines put above in the form result. If these any of those values are not entered, then the form result should not display those fields and text

Thanks

Greg Alexander

Try

<?
if (preg_match("/(ny|nyc|manhattan)/i",$_POST['ctl00$ContentPlaceHolder1$txtCompanyCity'])){
echo "<tr><td> This is to certify that I am an authorized officer of</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtCompanyName'] .  "</td></tr>
                        
                                    
                        <tr><td> Date:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtSignatureDate'] . "</td></tr>
                        <tr><td> Name:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtCompanyOfficer'] . "</td></tr>
                        <tr><td> Title:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtCompanyOfficerTitle'] . "</td></tr><br />
                <tr><td> Signature:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtSignature'] . "</td></tr>
                         <tr><td> Lien Amount $:</td><td width=\"" . $width . "\"></td><td>" . $_POST['ctl00$ContentPlaceHolder1$txtExactOwed'] . "</td></tr>
                         
                         <tr><td colspan=\"3\">Block:</td></tr>
                         <tr><td colspan=\"3\">Lot:</td></tr>";
}	
?>

Thanks - I put this code in and got a parsing error on the line below

Parse error: syntax error, unexpected '"' in /home3/speedyli/public_html/test-lien/formatEmail-field.php on line 330

if (preg_match("/(ny|nyc|manhattan)/i",$_POST['ctl00$ContentPlaceHolder1$txtCompanyCity'])){

Ray Paseur

If the error is on line 330, we may be missing a larger part of the picture. You have not posted more than a handful of lines of code, so we are guessing about where the error really might be. The if() with preg match above looks OK to me.

Should attach the whole php page. Thanks so much for your help

Thanks - I will try it

Have been away for a few hours, but I just got a look at that code. It looks very complex for what it appears to be doing -- providing sanity checks and error messages for an HTML form. I don't have time to rewrite it now, but I can help with a design pattern that might simplify things now, so when the time comes to modify the form you will have a more malleable script. See if this makes sense. It goes a little beyond the question of how to use preg_match in an if() statement, but hopefully it will stimulate your thinking about how the overall script structure can be simplified.

best regards, and good luck with the project, ~Ray
