When I fill my Contact Form

 

1) select option TITLE (MR. MRS. MISS)

2)First Name

3)Last Name

4) E-mail

 

I make validation to all data, The question is when I select title e.g. MR and then fill first name, last name AND e-mail IS NOT right (info2company.com) validation said *Email invalid, then I write my e-mail right (info@company.com) and click SEND button then validation said * title not entered.

 

I wanna hold my option data please help, I fight 3 days now...

 

here is my code:

 

register.php

 

<?php
/**
* Register.php
* Last Updated: 5-9-2009
*/
include("include/session.php");
?>

<html>
<title>Registration Page</title>
<body>

<?php

if(isset($_SESSION['regsuccess'])){
   /* Registration was successful */
   if($_SESSION['regsuccess']){
      echo "<h1>Registered!</h1>";
      echo "<p>Thank you <b>".$_SESSION['reguname']."</b>, "
          ."go back to <a href=\"register.php\">register page</a>.</p>";
   }
   /* Registration failed */
   else{
      echo "<h1>Registration Failed</h1>";
      echo "<p>We're sorry, but an error has occurred
          ."<br>Please try again at a later time.</p>";
   }
   unset($_SESSION['regsuccess']);
   unset($_SESSION['reguname']);
}

else{
?>

<h1>Contact Form</h1>
<?php
if($form->num_errors > 0){
   echo "<td><font size=\"2\" color=\"#ff0000\">".$form->num_errors." error(s) found</font></td>";

}
?>
<form action="process.php" method="POST">
<table align="left" border="1" cellspacing="0" cellpadding="3">

<tr>

I think you are making this too complicated. You could have the form post to the same page, and process on top.

 

if($_POST)
{
     // do validation and output error or thank you message
}

if(!$_POST OR $error)
{
     // show form
    echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">';
     // form elements go here
   echo '</form>';
}

thank you for post, I make this to practice my knowlege about php clases functions and I think its simple, but my question is <option value validation and hold my select value.

 

I think the problem is here:

 

<tr>
<td>Title:</td>

<td>
<select name="title" value="<?php echo $form->value("title"); ?>">
<option value="">Select One</option>
<option value="Mr">Mr.</option>
<option value="Mrs">Mrs.</option>
<option value="Ms">Ms.</option>
</select>
</td>
<td><?php echo $form->error("title"); ?></td>
</tr>

 

 

I need something like get my select option value back, can somebody help  :facewall:

You don't set the value of selects that way. the value of a select form comes from the options tags that are its "children" if you want to it have a default option already selected, you have to add the selected attribute to that specific option. In you case you will probably have to have if statements check what the latest value was, and then either make the option selected or not.

mikesta707 thanks for post, did you run my form and undertand my question, if I undertand you mean something like this.

 

<select name="title" value="<?php echo $form->value("title"); ?>">
<option value="">Select One</option>
<option selected = "selected" value="Mr">Mr.</option>
<option value="Mrs">Mrs.</option>
<option value="Ms">Ms.</option>
</select>

 

this is not that I ask (selected = "selected")

 

read my question, play with script and ask me if you don't undertand.
