[SOLVED] passing variables through a form

aebstract · March 14, 2007

Hello again,

I have a setup where I am displaying lots of information, all of it comes from contact forms and is stored in a database. Then can be viewed on one page, through the scripts. One feature is that you can click on an email address to send an email to that specific user. When you click their email, the form comes up fine, and I have been playing with this for awhile.. I am having trouble getting the variables passed through so that I can send the email and update the database. If anyone could take a look at my code that would be great.

<?php
header("Cache-control: private");
?>
<html>
<head>
<link href="stylesheet.css" rel="stylesheet" type=text/css title=default />
</head>
<body>
<div id="concon">
<?php

mysql_connect("localhost","hmg","hillpass"); 
mysql_select_db("hmg"); 


if (isset ($_POST['submit'])) {
$msg = $_POST['msg'];
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];
$mail = $_POST['mail'];


$query = "UPDATE contact SET readc='1' WHERE id=$mail;";
mysql_query($query);


mail ($email, 'Reply from HMG', $msg, 'From: [email protected]');
header ("Location: readmail.php");

}


$mark = $_GET['mark'];
if (isset($mark)) {
$query = "UPDATE contact SET readc='1' WHERE id=$mark;";
mysql_query($query);

header("Location: readmail.php");
}



$mail = $_GET['mail'];
if (isset($mail)) {

$result = mysql_query("SELECT * FROM contact WHERE id=$mail") or DIE(mysql_error());
while($r=mysql_fetch_array($result))

+ What would be the easiest way to get those variables through when I click the link? I can go through url if I have to, I just thought I could do hidden fields?

utherwun · March 15, 2007

As far as I know, albeit only a little, but the only way you can send hidden items and keep them hidden is by submitting them via a form and using $_POST. I've had to do this for several pages utilizing Javascript as presubmit verification and recalling a PHP script to basically display another page.

I know it's basic but possibly something overlooked... hope it helps some.

edit: And apparently I can't read for comprehension either. :embarassed:

Does the readmail.php use $_POST data to get the information or is it just reloading the same page? I'm getting a little lost in the code. Also, is it giving you any specific error?

aebstract · March 15, 2007

See, that is what I am trying to do, is pass them through a form.. though I am coming up short. I'll try and post the bits that are dealing with that here to make it easier to see:

This part is after you click send on the form, ( the if submit comes in to play )

if (isset ($_POST['submit'])) {
$msg = $_POST['msg'];
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['email'];
$mail = $_POST['mail'];


$query = "UPDATE contact SET readc='1' WHERE id=$mail;";
mysql_query($query);


mail ($email, 'Reply from HMG', $msg, 'From: [email protected]');
header ("Location: readmail.php");

}


$mark = $_GET['mark'];
if (isset($mark)) {
$query = "UPDATE contact SET readc='1' WHERE id=$mark;";
mysql_query($query);

header("Location: readmail.php");
}

Okay, here is the part where, when you click an email address on the main section, you get this form:

$mail = $_GET['mail'];
if (isset($mail)) {

$result = mysql_query("SELECT * FROM contact WHERE id=$mail") or DIE(mysql_error());
while($r=mysql_fetch_array($result)) 
{ 
$id=$r["id"];
$firstname=$r["firstname"];
$lastname=$r["lastname"];
$email=$r["email"];
$body=$r["body"];

echo "
<div id=uploadform>
<table>
<tr>
<td align=right>To:</td><td width=5></td><td>$firstname $lastname</td>
</tr><tr>
<td></td><td></td><td>$email</td>
</tr><tr>
<td></td><td></td><td>
<form action=readmail.php method=post>
<input name=$mail type=hidden value=$mail>
<input name=$firstname type=hidden value=$firstname>
<input name=$lastname type=hidden value=$lastname>
<input name=$email type=hidden value=$email>
<textarea name=msg rows=5 cols=60></textarea><br />
<input type=submit name=submit value=Send />
</form>
</td>
</tr>
</table>
<div align=right><a href=readmail.php>back</a></div>
</div>
";

}

} else {

I closed that bit of code off at the else, because the first part you go to when visiting this page is in that else.

Hope this helps out so that I can get some help

ok lets try this approach,,, what are you expecting to have happen and what is actually happening??

aebstract · March 15, 2007

I'm expecting that when you fill out the form, it should send an email to the person. It should also update the database, it should update the row with the specific unique id and change readc to 1. Neither of which it is doing.

O.o
