PHP - Hidden Data.

I have created a form which allows people to add data to a database.  However, I want to replicate the form across several pages and give each page a category.

For example, if I have a website based on sport.  I have a page which enters information into the baseball category, a page which enters information into the ice hockey category, a page which enters information into the soccer category etc.

Can someone advise how I would do this?

Is there anything wrong (or insecure) with using hidden form fields?

I am working on a page where the user can choose one of 4 different subscription options.

The approach I was going to use is to have a separate form for each plan, and when the user chooses one, submit a hidden form value so my script knows which subscription plan to grab out of the database.

Thoughts?

Hi I have an index.php with three drop down boxes on, each drop down uses an SQL statement to pull seatNumber from 'seats' each seat number has a UI and a forgein key field called SrideID.

I have the buttons on the dorp down boxes going to dd-check.php, here the seat chosen is posted and a simple echo(just testing it works atm)

for me to do any queries I also need the SrideID within the dropdown box, i tried adding it within the <option></option> but it only made the drop down duplicate.
1
1
2
2
3
3
ect.....

what i would like is for the SrideID field to be included with in the dropdown box but hidden so i can post it to  the dd-check.php and then show the time and price of that particular ride.

here is the table and the code so far. Thanks for any help.



CREATE TABLE `ride` 
(
`RrideID` tinyint(1) default NULL,

INSERT INTO `ride` VALUES (3, 'Ice Blast', 4, '3.00');

CREATE TABLE `seats` 
(
`seatID` int(8) NOT NULL default '0',

INSERT INTO `seats` VALUES (72, 3, 4);
INSERT INTO `seats` VALUES (73, 3, 5);




code for index.php

<table width="200" border="1">
  <tr>
 <h1>Swinging Ship</h1>
<?php
echo '<form method="post" name="f1" action="dd-check.php">';

$result = mysql_query($query_r);  

echo"<select name='seatNumber'><option value=''>Select Seat</option>";
while( $row = mysql_fetch_array($result) )

}  
echo '</select>'; 
mysql_free_result( $result ); 
echo "<input type='submit' value='Submit'>";
echo "</form>";
?>
  </tr>
</table>



code for dd-check.php


<?php
$result=$_POST['seatNumber'];
echo " <p> the seat choosen is : $result <p> ";

//TEST PULL ALL QUERY
$testPullAll = mysql_query("SELECT * FROM ride");

echo "<table border='1'>
  <tr>
  <th>Name</th>
  <th>Duration</th>
  <th>Price</th>
    </tr>";

while($row = mysql_fetch_array($testPullAll))
  {
  echo "<tr>";
  echo "<td>" . $row['name'] . "</td>";
  echo "<td>" . $row['time'] . "</td>";
  echo "<td>" . $row['price'] . "</td>";
  echo "</tr>";
  }
echo "</table>";
?>



the end result will be a query in dd-check.php that says something like

if [hidden SrideID = 1]
echo 'the name, time and price of the ride'
if [hidden SrideID =2
echo name, time and price
if number 3 then echo the rest of the row.

any help would be great, i've been using trial and error so far (since yesterday afternoon) with no success  =(

ps sorry for the long post, i wanted to try and explain everything the best i can. =)

Hello,
My question is how to send values over and over without using forms or even hidden forums. I have tried to use sessions but it didn't work out for me. Any suggestions!

Hey all, i have a little problem.

I have a form, and when submitting, i need to use the ID that i put in the $_GET array earlier.

When you're entering my site, and clicks a certain link, the $_GET will store show=1, and when you're submitting the form on the page, the value of 'show' is needed on the redirect page.. I thought that it would be smart to transfer it with a hidden textfield, but somehow it fails?

<form id="comment-form" action="comment_profile.php" method="POST">
                                    <fieldset>
                                        <div class="field">
                                            <textarea name="comment-field" rows="2" cols="66"></textarea>
                                            <input type="hidden" name="pofileid-field" value="<?php echo $_GET['show']; ?>" /> // <--- Here is the hidden field.
                                            <input type="submit" name="submit-field" class="submit" value=""/><i> (HTML tags kan bruges)</i>
                                        </div>
                                    </fieldset>
                                </form>

Above you can see a piece of my code, and i marked the hidden field aswell.
What i do not understand is, why isn't the hidden fields value return the value of show when i check in comment_profile.php, as that is where it returns?

Thanks in advance

Hello everyone, I have a question.

I'm trying to figure out a way to make it so that when a user visits a page for a certain file, they are given the file to download but can't see the link to that file.

Example:
There is a file on http://serverB.com/file.rar
A person goes to http://serverA.com/?file=file.rar
They can download http://serverB.com/file.rar without seeing the link to that file.

Is there any way to do this?

Thanks.

Hi Guys,

Appreciate any help here please...

Basically I want to hide some inputs on my registration page and populate them will default values.  Everything works okay, apart from the input below:

Code: [Select]
<input type="hidden" name="seek_location" value="Anywhere">
When I use the above, the MYSQL database field for seek_location is left empty...

I've noticed that the code below pulls the location into a dropdown list.  You know the kind of thing, Australia, UK, USA etc etc:

Code: [Select]
$seek_location = $wcr[$seek_location];
Code: [Select]
<? $p=0;asort($wcr);reset($wcr);
while (list ($p, $val) = each ($wcr)) {
echo '<option value="'.$p.'">'.$val;
}
?>
So, all I want to do is have:

Code: [Select]
<input type="hidden" name="seek_location" value="Anywhere">
Populate seek_location with Anywhere

Any help appreciated
Thanks
Rob

I know that it is possible to see what is sent by looking at livehttpheaders, but how do you know how hidden variables are generated?

I don't think that that's possible to see that from live httpheaders.

i have the following code:
            <li>Have you read the <?php echo link_to('FAQ','util/faq') ?> ?
                 <select id="yesnolist" onChange="getChoice(this.value)">
                    <option value="yes" selected="selected">Yes</option>
                    <option value="no">No</option>
                 </select>
            </li>   
             <input type="hidden" name="text" size=30 id="yesandno">
             <?php
                if ($_GET['yesandno'] == "no")
                {
                   echo "anything!!!!!!!!!!!!!!!!!!!";
                }
            ?>

then my java script for getCoice():
function getChoice(val)
  {
      yesNo = new Array("Yes", "No");
      var getsel = document.contactus.yesnolist.value;
      var e = document.getElementById("yesnolist");
      var strUser = e.options[e.selectedIndex].value;
     
      document.contactus.yesandno.value = strUser;
      alert(document.contactus.yesandno.value);
      return strUser;
  }

my alert will gove yes or no depending on what i chose in the dropdown
but HOWCOME it does not go into the if  ($_GET['yesandno'] == "no") ????

please help???

so I have this code:
Code: [Select]
<input type='checkbox' name='title8' value='$title8' /></td><td><strong>$title8</strong> <br /> $date8 <br />$ $price8<input type='hidden' name='price8' value='$price8'> how do I make is so that the hidden field is only going to submit if the checkbox is checked........

Hi

I am using Comet programming and the hidden iframe (the only real way to push data with php)

I have this working perfectly on one server but another it just shows a constant blank screen. I have both servers in the php.ini with output buffering to On, no set size but also the script itself outputs over 250 characters to compensate for some browsers buffers.

I just don't understand why it works on one server but not another! Just for note, it only does this when i use the sleep() function...but like I say this works on one of my servers.

Here is the example program to test the functionality. On this site is works : www.gookymedia.com/comet  but here, the exact same code does not : www.jointsocial.com/comet

This is one of the most baffling things I have come across in php programming so far, and believe me I have written some complex applications over the years! I could do with someone to point out whats going wrong (if anyone has ever done this before)

Hi
I've got a form that users enter an identification pin in for their first question  as well as clicking a radio button(Q1.php) . They click submit and the answers are put through a couple of multiplication function and then placed in a table (alongside the pin)  via Q2.php.

 On the Q2 page I want to place the 2nd question that the user needs to answer. 

Rather than making them retype the pin I was hoping to process it as a hidden field - being picked up from their Q1.php entry.
This 'hidden pin echo ' process will continue throughout Q2- Q10 pages.

However - I can't seem to include any php in the page after the Q1 form has been processed.  Have I got my php tags messed up?

<?php
$con = mysql_connect("localhost","ca","d");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("candango", $con);

$q1 =$_POST['q1'];
$pin =$_POST['pin'];


$ans1 = $q1 * 3;
$ans2 = $q1 * 5;
$ans3 = $q1 * 2;


$enter_sql= "INSERT INTO aapcm2 (pin,ans1, ans2, ans3)
VALUES ('$pin','$ans1','$ans2','$ans3')";
$enter_query =mysql_query($enter_sql) or die (mysql_error());
?>

<body>

<p>Thank you - You have successfully entered your answers.</p><form action="q2.php" method="post">
