Losing Variables

[Cutty382]

I am creating a form that when you take the input information it emails it to me...now what I want to do is have a page between the form and the final script that is like a confirmation page so the user can go over the information they are going to submit before they submit it... I can get the information posted on the confirmation page but when I try to move from the confirmation page to the final thank you page where my email script lies I lose all the variables and I receive a blank email....what do i do? all help is appreciated. Thanks

one of two ways:

1.) You put a hidden form on the confirmation page that posts to the final page
2.) You store the information in a session and read the info from the session on the final page

I have been trying to do the Session thing but I cant seem to figure that out and how would I put a hidden form on the confimation page? can you point me in a direction where I can find out what I need to know? Thanks.

form1.html

<form action="form2.php" method="post">
  Name: <input type="text" name="name"><br>
  Age: <input type="text" name="age"><br>
  <br>
  Tag-Line: <input type="text" name="tag"><br>
  <input type="submit" name="submit" value="Submit">
</form>

form2.php

<?php
if(!empty($_POST))
{
  $hidden = '';
  echo '<form action="form3.php" method="post">';
  foreach($_POST as $var=>$val)
  {
    if($var != 'submit')
    {
      $hidden .= '<input type="hidden" name="'.$var.'" value="'.$val.'">';
      echo '<b>'.ucwords($var).':</b> '.$val.'<br>';
    }
  }
  echo $hidden.'<input type="submit" name="submit" value="Submit">
  </form>';
}
else
{
  echo 'You need to fill out the form before you get here.';
}

form3.php

<?php
if(!empty($_POST))
{
  // Now, deal with inputted info as a regular form post
  // and send the email
}
else
{
  echo 'There\'s nothing to send!!';
}

Parse error: syntax error, unexpected T_VARIABLE in D:\WEBSITES\davidhenryagency.com\wwwroot\htdocs\Salon\form2.php on line 4

I am getting that error when I try to process the original form

[bpat1434]

Fantastic!! What's your code? Did you copy & paste my post? Shouldn't do that. I didn't say it would work, just that it was a template to work from. Some starting code.

[Cutty382]

my code is pretty long dont know if i should try to post it here, my form.html code is just like yours but with my variables of course and then for the confirmation.php i have basically html code with php on certain lines calling the variables so I can see them where I want so what I did was take your form2.php code and put that before my html code and then I put your form3.php code on my script page with my other script that handles the email inside your script....I am obviously new to this and I can understand to a point whats going on with this code, your code on the other hand threw me for a loop haha didnt really know where to go with that. I am appreciating that you are trying to help me and please bear with me if you can. Thanks.

[bpat1434]

You get an error probably from a non-ending line. Search in your form2.php file for a line (most likely line 1) that doesn't have a terminator character (😉.

I just copied & pasted my code above into the proper files (form1.html, form2.php, form3.php) and tested. Works perfectly fine. So somewhere in your code, something is wrong. Post your code, and I'll take a glance at it.

[Cutty382]

I cant seem to find anything like that and the error keeps pointing me to the first time I try to introduce the $hidden variable

[bpat1434]

Then post the corresponding code... from that line and above....

[Cutty382]

<?
if(!empty($_POST))
{
**$hidden = '';

that is line 1 thru 4 and $hidden=''; is on line 4 where it is telling me that Parse error: syntax error, unexpected T_VARIABLE

[bpat1434]

so is "**" part of the code, or just noting the line?

I'm guessing there's something else.... what is the full code, from start to finish? Just go ahead and post it, I'll work through it....

[Cutty382]

<?
if(!empty($POST))
{
$hidden = '';
echo '<form action="formscript.php" method="post">';
foreach($POST as $var=>$val)
{
*if($var != 'submit')
{
**$hidden .= '<input type="hidden" name="'.$var.'" value="'.$val.'">';
echo '<b>'.ucwords($var).':</b> '.$val.'<br>';
*}
}
echo $hidden.= '<input type="submit" name="submit" value="Submit">
</form>';
}
?>

The is really only the first part of it it was way too long and alot underneath that is all just really html stuff that at this point is pointless i believe it has nothing to do with what I am trying to do with php and the form...

[bpat1434]

Does your server allow short open tags? Could be the cause, but I doubt it...

Not sure what is going on... what version of PHP are you running?

[Cutty382]

I have no clue like I said I am just new to this and when I need to use php usually I find a tutorial or a past written script and manipulate it to what I need I can kinda work it out that way then I just post it. I am trying to learn more but its basically learning on the fly here is there another way I can go about it? What about sessions? that seems like maybe a better way to do this type of thing anyway I just couldnt manipulate the code for that I dont really understand it.

[bpat1434]

well, for sessions you'd do this (in place of the code that isn't working right now):

<?php
if(!empty($_POST))
{
  session_start();
  foreach($_POST as $var=>$val)
  {
    if($var != 'submit')
    {
      $_SESSION[$var] = $val;
    }
  }
}

Then, in the third form, just loop through the session to get the values...

<?php
session_start();
foreach($_SESSION as $var=>$val)
{
  echo $var.' has a value of '.$val.'<br>';
}

You'd do that to first get output if you're not sure about what you're posting. Otherwise, just extract it like a normal post:

<?php
session_start();
$age = $_SESSION['age'];
$name = $_SESSION['name'];
$tag = $_SESSION['tag'];

[Cutty382]

why do you write if(!empty) when you start the code? what does !empty mean? I have never seen that before

[bpat1434]

well, ! is the operator for NOT so !TRUE = FALSE; !FALSE = TRUE.

empty() checks to see if a variable/array is in fact empty. Many things equate to empty, those being "0", Null, FALSE, and a var declared by a class but no value assigned yet.

So, by saying if(!empty($POST)) we check to see if the $POST array is not empty. If it's not empty, then values have been posted. Otherwise, you'll get errors in your code about non-existant keys.
