PHP Sticky fields

[overflo]

Hi.I have the following code (a function) to display and process a html form. What I need is for it to have "sticky fields" so that if there is an error and the message is displayed, when they are returned to the form the details that were correctly input are still there.

function show_page1(){
$action = $_SERVER['PHP_SELF']."?chall=page1";;
		
if(!isset($_POST['submit'])){
$content = "<div id='form'>
			 <form id='form1' name='form1' method='post' action=$action>
			  <table width='303' height='181' border='0'>
			   <tr>
			    <th width='105'>Name:</th>
				<td width='196'><input name='name' type='text' id='name' size='30'  /></td>
			  </tr>
			  <tr>
			   <th width='105'>Suburb:</th>
			   <td width='196'><input name='suburb' type='text' id='suburb' size='30'  /></td>
			  </tr>
			  <tr>
			   <th scope='row'><div align='left'></div></th>
				<td><div align='left'>
				 <input name='submit' type='submit' value='Submit'>
			    </div></td>
			   </tr>
										
			 </table>
			</form>
		   </div>";
}else{
	if($_POST['name']==""){
		$message .="<p>Please enter a name</p>";
	}else{
		$name = mysql_real_escape_string($_POST['name']);
					}
	if($_POST['suburb']==""){
		$message .="<p>Please enter a Suburb</p>";
	}else{
		$name = mysql_real_escape_string($_POST['suburb']);
	}
					
	if(!$message==""){
		$content .=  $message . "<p>Please click <a href=$action>here</a> to go back and try again</p>" ;
	}else{
		//sql insert queries go here
	}
						
}
}

any suggestions greatly appreciated

sorry - duplicated post....

Here's what you need to do:

* put the main PHP above the form so you can check all the variables etc first - so change if the code to be more like:

if(!isset($_POST['submit'])){
// do something
} else {
// do something else
}

to

if(isset($_POST['submit'])){
// process the post variables

// if all is fine...
$sucess = true;
}

* if it's sucessful and no errors , you no longer need to show the form, otherwise you need to still show the form.

* In the form, change the fields so they read like this:

<input name='name' type='text' id='name' size='30'  value='<?= $name ?>' />

This puts the posted value into the field if we're still showing the form.

Hope that helps and is not too confusing.

Here's a script I use which also includes some basic anti-spambot functions - you'll need to set your own mailing routine, but otherwise, this works great:

<?php

$_POST = array_merge($_POST, $_GET);
$error = "";
$name = isset($_POST["name"]) ? htmlspecialchars($_POST["name"]) : null;
$company = isset($_POST["company"]) ?  htmlspecialchars($_POST["company"]): null;
$title = isset($_POST["title"]) ? htmlspecialchars($_POST["title"]) : null;
$country = isset($_POST["country"]) ? htmlspecialchars($_POST["country"]) : null;
$email = isset($_POST["email"]) ?  htmlspecialchars($_POST["email"]): null;
$message = isset($_POST["message"]) ?  htmlspecialchars($_POST["message"]): null;
	 
	 
if(!empty($_POST["submited"])){



// check if any of the SPAMBOT criteria are true

	if(preg_match("/bcc:|cc:|multipart|url|Content-Type:/i", implode($_POST))) {
		$spam=true;
	}
	if (preg_match_all("/<a|http:/i", implode($_POST), $out) > 3) {
		$spam=true;
	}
	if(!empty($_POST['emailagain'])){
		$spam = true;
	}
	if(empty($_POST['name'])){
			$error = true ;
	}
		if(empty($_POST['company'])){
			$error = true ;
	}
		
		if(empty($_POST['country'])){
			$error = true ;
	}
	
	// if e-mail is not formatted correctly, show error message
	if(!eregi("^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$", $_POST['email'])) {
			$error = true ;
	}
	
	
	if(empty($_POST['message'])){
		$error = true ;
	}
	if($_POST['formtime'] < time()-3600)  {
		$spam=true;
	}


$errorMessage = "Please fill in all the fields.";


if(empty($error) and empty($spam)){
// create and send the email

$emailMessage = "";

$emailMessage .= '<b>Company:</b>' . $company. '<br>';
$emailMessage .= '<b>Name:</b>' . $name. '<br>';
$emailMessage .= '<b>Title:</b>' . $title. '<br>';
$emailMessage .= '<b>Email:</b>' . $email. '<br>';
$emailMessage .= '<b>Country:</b>' . $country. '<br>';


$emailMessage .= '<b>Enquiry:</b>' . $message. '<br><br>';
$newlines   = array("\r\n", "\n", "\r");
$replace = '<br>';
$emailMessage = str_replace($newlines, $replace, $emailMessage);		


	$mail = new PHPMailer();
	$mail->IsHTML(true);
	
	$mail->From     = "my name";
	$mail->FromName = "Some Website";
	$mail->Subject = "Enquiry from Some Website";
	$mail->AddAddress("some@email", "Some Person");
	
	$mail->Body = $emailMessage;
	$mail->Body   = eregi_replace("[\]",'',$mail->Body);
	$mail->AltBody= strip_tags($mail->Body);
	
	if(!$mail->Send()) {
	
		  echo 'Failed to send mail';
	
	} else {
	
		$sentemail = true;
	
	}
}

I usually just do something like this........

<?

//check the submit button has been pressed
if($_POST)
{

//check fields arent blank
if($_POST['name']!="" &&
$_POST['telephone']!="")
{

//do further validation and upon success, mail
etc etc
mail();
unset($_POST);
$msg = 'Thank you, your details have been submitted';

}
else
{
$msg = 'Please ensure fields arent blank';
}


}
?>

<html>

<?=$msg?>

<form method="post" action="<?=$_SERVER['REQUEST_URI'];?>">

<input type="text" name="name" id="name" value="<?=$_POST['name']?>" /><br />
<input type="text" name="telephone" id="telephone" value="<?=$_POST['telephone']?>" /><br />
<input type="submit" name="submit" value="Submit" />

</form>

</html>
